Our plate rolls are available in over 60 sizes with capacities from 16 gauge to 6 inches . Carell's range of standard models provides unmatched flexibility and coverage of most any plate rolling requirement. They can be built to handle a wide range of specific rolling requirements that includes shorter or longer lengths from 20 inches to 24 feet, custom roll cambers, slotted rolls for plate with flanges-lips-ribs, patterns for corrugated material, vertical rolling applications and more! 4ROLL PLATE ROLL MODELS 4 ROLL 3 Roll Double Initial Pinch Plate Roll 3 Roll Double Pinch Manufacturing Range 1' to 26' Long - .05" to 6" thick also known as: 3 Roll Double I nitial Pinch BACK TO TOP They are available from light to extremely heavy capacities and sometimes referred to as "double pinch pyramid plate rolls’"or "double initial pinch plate rolls". Three roll styles have fixed position top rolls and two offset rollers or "lateral rolls", one on each side and include drop end yokes for easy extraction of the work-piece .Three Roll machines generally require pre-bending the leading end, running the sheet through the machine to pre-bend the trailing end then switching roll rotation direction to roll the cylinder body. 3ROLL PLATE ROLL MODELS 3 ROLL VARIABLE GEOMETRY 3 Roll Variable Translating Geometry Plate Rolls 3 Roll Translating Geometry Manufacturing Range: 3' to 26' Long - 1/4" to 12" thick (also known as 3 Roll Variable Translating Geometry) BACK TO TOP Variable Translating Geometry Plate Rolls are built for medium, heavy to extremely thick plate applications. The top roll moves up/down and the lower two rolls each move horizontally . This lower roll movement allows increasing the offset distance from the top roll and commensurately increasing mechanical advantage in bending. By adjusting the geometry they can be used similar to single pinch, double pinch and pyramid style machines and require minimal sheet movement during the pre-bend operations. 3ROLL VARIABLE TRANSLATING GEOMETRY MODELS 3 Roll Initial Pinch or Single Initial Pinch Plate Rolls Initial Pinch-Hydraulic & Mechanical 3' to 12' Long - 1/2" to 26Ga Capacites (also known as 3 Roll Single Initial Pinch or I.P. Rolls or Slip Rolls) BACK TO TOP Initial Pinch or Single Initial Pinch Plate Rolls are generally for lighter capacity applications and may be electro-mechanical or hydraulic. The upper roll is in a fixed position; the lower pinch roll can move up/down to pinch the material. The third roll (the forming roll) is also adjustable. They are cost effective but in contrast may be more labor intensive in a production setting. 3ROLL INTIAL PINCH PLATE ROLL MODELS INITIAL PINCH Vertical Format Plate Rolls Vertical Rolls BACK TO TOP Vertical Format Plate Rolls can be of nearly any geometry, double pinch, single pinch or pyramid.

The TBH Series with capacities to 6” coupled with a selection of over 55 standard models provide unmatched flexibility and coverage of most any plate rolling requirement. Our 3 Roll as well as 4 Roll Plate Rolls can be designed and built to handle a wide range of specific rolling requirements to include shorter or longer lengths from 20 inches to 24 feet, custom roll cambers, slotted rolls for plate with flanges-lips-ribs, corrugated patterns for corrugated material, vertical rolling applications and more. TBH SERIES TBH Series Full Hydraulic 3 Roll Plate Roll BACK TO TOP TBH Overview The TBH is a double pinch design plate roll with independent adjustment of the two lower rolls on inclined sliding guides. This allows to pre-bend and roll both plate edges with only one insertion (no need to remove and turn the plate). The three rolls drive assures the best plate feeding also when rolling thin plates and the large opening between the top and lower rolls increases machine flexibility. The TBH bending machines are equipped with the exclusive Parmigiani Parallelism System (PPS) for rolls parallelism control (closed ring type). The PPS assures the max precision in rolls positioning also after several years of intensive work. Linear sliding guides with anti-friction material (AVG System).(No maintenance; High loading and carrying capacity; Smooth and stable positioning).All rolls, mounted on spherical roller bearings, are driven by separate hydraulic motor for each roll. The TBH bending machines are equipped with the multi-bearing system that guarantees the highest reliability even for intensive productions and cone bending. With the TBH Series we exceed your expectations. How do we exceed your expectations? It’s simple: The all-new VBH Series was created from the belief that every feature, every innovation, must be focused on helping you grow your bottom line. This led our engineers to design the next generation of plate rolls, concentrating on four key areas of machine performance: STRENGTH: Linear sliding guides and multiple bearing rolls support system. POWER: High torque reduction unit for reduced number of rolling passes. PRECISION : Digital control of the roll parallelism with proportional valves. CONTROLS: Infinitely variable roll adjustment speeds, Infinitely variable central lower roll pinching pressure, shell calibration working modes, extended i-diagnostic system... are only some of the features that you can control directly from the operator mobile panel, just moving a finger. FEATURES TBH Features DISCOVER THE EXCLUSIVE FEATURES OF THE TBH SERIES! BACK TO TOP ​ • No friction - less than swing design • Direct load to the plate • Less vertical power on top roll • Lower bending diameter Get more with linear guides ALG System Anti-friction Linear Guides The linear guide design is the only system that can grant the necessary machine stiffness and the perfect geometry for all kind of bending operations. The linear design allows a compact geometry of the machine ("minimum centerline distance between the two side rolls", impossible to obtain with the swinging design) that is essential for bending precision and accuracy. The linear design allows you to work in the best and ideal geometrical conditions when rolling high yield strength materials, reducing the shell spring back reopening effect and obtain a much smaller bending diameter when compared with the swinging design Built For Heavy Work HMB System Heavy Multiple Bearings ​ Each bending roll is supported by 4 heavy-duty self-aligning spherical roller bearings (double raw type). Each bearing is oversized in order to withstand the whole bending load. Thanks to the HMB exclusive design, with four oversized bearings fitted into a swiveling housing, the roll can freely deflects along it’s full width during the rolling process. This guarantees an optimal distribution of the load on the supports even during the cone rolling process and increases the machine's reliability and life. Moreover, the multi bearing system with swiveling housing design greatly reduces the maintenance and the need for lubrication (permanent lubrication). The Powerful and Reliable Choice Full Frame Extended Design Parmigiani plate rolls have the most heavily sized frame you can find in the market. Unlikely slim frames covered with thin thickness plates that you can find on all machines in the market, makes our frame design look definitively oversized.The exclusive full frame design withstands all bending forces and guarantees stiffness and performance throughout years of service.This unique machine frame, with extended design for added rigidity and strength, are welded fabrication. After welding all frames are stress relieved and then machined on CNC milling machines Friction free - Maintenance free AST System Anti-friction sliding technology Each Rolls support is machined with anti-friction material in the sliding area. This system drastically reduces the maintenance and sliding friction, less than in a planetary machine. More power - More torque HTT System High transmitted torque The rolls driving is realized by independent hydraulic motors via planetary gear transmission directly coupled to each driven roll. The independent rolls hydraulic drive assures and automatic speed compensation between the top and lower rolls and an optimal distribution of the torque on each roll during the working phase. The HTT system allows the best plate feeding and the highest driving torque of any competitive machine. A winning combination for those looking for performance of the highest level. TBH Technology TBH Technology BACK TO TOP Everything is under control Are you loosing production hours and days checking around the machine for which connection wire, PLC card, push-button or fuse are faulty? Forget these kind of problems with PARMIGIANI's i-Diagnostic system for immediate fault detection. The i-Diagnostic is a revolutionary diagnostic system that supervises all the main functions of the machine, with an easy to use and intuitive control panel interface. From the touch-screen you can control almost all electrical connections around the machine; all PLC modules; all micro-switches (You can check also if they are engaged /energized or not) and more.... i-Diagnostic: a revolution in customer support Instantaneous fault detection instead of troubleshooting Detailed information on type and location of the fault TBH Technology ACTIVE EXTENDED DIAGNOSTIC PARMIGIANI PARALLELISM SYSTEM The PPS is the most advanced parallelism system available on the market today. The rolls parallelism in a plate bending machine is a key factor for production accuracy. The capability to maintain precision over years of performance is also another critical point. For this reason we employ the best of today's available technology with digital control systems and hydraulic flow control via proportional valves. We have designed a system resistant to wear that will give you years and years of trouble free performance, keeping the machine positioning precision just like your first day of operation! The top and bottoms rolls parallelism is fully controlled by a digital “high speed” FIELD BUS system. The package includes a set of hydraulic proportional valves with high performance digital control cards, matching the high speed of the FIELD BUS system. This digital technology (the loop control is 20 times faster than PLC-based electronic controls) joined with the hydraulic proportional valves, provides a parallelism precision of about 0.1 mm. Lifetime precision Digital control technology with hydraulic proportional valves Parallelism precision 0.1 mm ADVANCED WIRING SYSTEM Plug and play technology Do It by yourself "Assemble and plug in – that’s all!" Quick and simple plug connections replace elaborate wiring. • Avoids wiring errors • Shortens start-up time • Quick swapping of cables  The wiring of the machine is achieved by Plug and Play connectors and digital distributors. The cabling system with connectors is more reliable over time, resistant to environmental contamination and vibration and allows for quick and easy maintenance. With our FACILE® Plug and Play system you can change a wiring connection (to the hydraulic valves or the encoders or potentiometers, to a micro-switch etc…) with pin plug connector, without unscrewing any electrical wire. Same procedure for all PLC modules! Without the need of a skilled electrician! With the purpose of increasing your independence from third parties all software are loaded in static memory cards, (like the ones used in digital video cameras) and not in volatile Eprom! This means that you will almost never lose the software, even when you need to change the PLC unit. Our plug-play system is a military approved technology! Digital control technology with hydraulic proportional valves Parallelism precision 0.1 mm Infinitely variable adjusting speeds Infinitely variable bending pressure The hydraulic system is the operative core of your VBH: it runs everything from the bending rolls drive to the bending rolls movement, tilting and all other machine attachments. This is why we invested a lot in research and development to give you a smooth, precise and highly responsive system. Through digital controls the system is managed by dedicated hydraulic proportional valves (pressure and flow) that allows you to select the most convenient speed during each production step (vs. other brands machines that give you only one or two selectable speeds) and the maximum central lower roll pinching force in order to adapt it to the characteristics of the plate being worked. The possibility to select low pressures for thin plates widely extends the range of the machine. With infinitely variable pressure and speed adjustment the operator will have full control of the process in any bending situation. ADVANCED HYDRAULIC SYSTEM TBH Controls TBH Controls BACK TO TOP Everything is under control Dedicated controls from PARMIGIANI for plate rolling cover an entire range of applications. All software is developed in-house by Parmigiani technicians with great experience in plate rolling. From the simple, compact DIGIMATIC control to the STRADIVARI (unlimited number of axis) there's a PARMIGIANI control for nearly every application. Parmigiani NC and CNC controls are 100% in house developed . Controls are an essential requirement for executing precision rolling applications. Select the "SAVE&BEND" with its 10.4” display or the "FAST" with a 15” display or the "STRADIVARI" with a 19" display.

Today many plate rolls have CNCs with data tables that draw from decades of rolling experience, which has made the process much more predictable. With predictability also comes automation. Some plate roll operations now have automated the loading, rolling, and unloading, producing precisely rolled workpieces time after time. QUICK LINKS Quick Links by subject: Plate Roll Manufacturers Machine Capacity Pre-Bending vs. Rolling Ratings Pre-Bending Ratings Rolling Ratings Automation Three Roll Initial Pinch Double Pinch Automatic NC or CNC Controls Variable Geometry Plate Rolls True Pyramid Machines Two Roll Machines Vertical Format Plate Rolls Optional Equipment & Accessories Cone Rolling Devices Lateral & Overhead Supports Extended Roll Shafts Roll Movement Up/Down Roll Balancing Plate roll manufacturers Plate roll manufacturers commonly rate machines according to baseline material yields between 36 to 38,000 psi. When choosing a roll you must refer to your mill delivery certificates, to your proposed supplier or to the Internet to specifically verify the average yields of the plate you need to roll. In our current manufacturing environment, the term “A36 Steel” has little correlation to the actual yield since the A36 generalization encompasses many specific sub-denominations. Some of these may have yields strengths of 70,000psi or more. The old common term “Mild Steel” will generally represent steels with yields of 45,000 to 55,000 psi. Machine capacity must be commensurate to your material yield. Most roll manufacturers can provide tables or graphs that allow you to match machine capacity to the material yield. Pre-Bending vs. Rolling Ratings will often be presented in numerous formats and tied to a minimum shell diameter at a given thickness for each Plate Roll model. The Pre-Bending operation is performed at the leading and trailing edge of the sheet (in most cases, the eventual seam). Sheets cannot physically be bent completely to the leading edge and will thus leave what is referred to as an ‘Unbent Flat’. As a rule of thumb, the minimum you should expect for an unbent flat length is 1.5 times the material thickness. This may approach 2.5 to 3.5 times the material thickness for thicker plate. It is this pre-bending operation which attempts to reduce the unbent flat to the minimum possible length which requires the most power from the machine. This operation is also very critical as care must taken to ensure that the sheet does not disengage from between the rolls. Because of this “safety factor” claims of unbent flats equal to 1.1 times the material thickness should be thoroughly investigated as it is rare that this can be achieved. Pre-bending ratings with the shortest possible unbent flats are necessarily lower than the overall rolling capacity rating for any given machine. You must be mindful when reviewing machine ratings since the maximum total rolling capacity is generally expressed with the intrinsic requirement of multiple rolling passes, longer un-bent flats and larger minimum shell diameters, even if not entirely clear from reading a simple roll specification. Un-bent flat lengths for any given sheet are a function of thickness, width, cylinder diameter, machine geometry, material yield, top roll size, operator proficiency and other factors. Rolling ratings anticipate that the plate is in motion, translating through the machine. This is called “dynamic” as opposed to the “static” pre-bending operation when the sheet is held between the rollers and one or more rolls move upward to “curl” the leading edge. Dynamic rolling mode will always allow a greater thickness to be rolled than can be bent during static pre-bending. Automation in the workplace is becoming more common as pressure increases to reduce labor costs. Most all CNC and NC controlled machines are 4 roll types. Automated controls are recommended for high volume or significantly repetitive cylinder or shell production or to roll complex shapes that are not easily reproduced by using manual machine controls. Multiple bends, variable radius bends, ovals and the like are some examples. Over automation on a roll when the production volume is not significant can be a costly mistake. Three Roll Initial Pinch or Single Initial Pinch Plate Rolls are generally for lighter capacity applications and may be electro-mechanical or hydraulic. They work by "pinching" the flat sheet between two counter-opposed rolls while the third offset roll or ‘bending roll’ moves upward to contact and then bend the sheet. When rotation of the rollers is activated, the sheet exits at a given radius. With the sheet cut to the developed length and the bending roll properly positioned; the part is rolled into a cylindrical form, where it can then be welded at the seam to produce a cylinder. The upper roll is in a fixed position; the lower pinch roll can move up/down to pinch the material. The third roll (the forming roll) is also adjustable. To remove a rolled cylinder, it must be extracted from off of the top roll. Machines are generally equipped with some type of release mechanism on the top roll to allow extraction of the cylinder. Typical methods are either a forward tilting or releasing top roll or a removable end yoke. In most applications, these machines require removal and re-insertion of the sheet in order to pre-bend both ends. They are cost effective but in contrast may be more labor intensive in a production setting. There were many large mechanical initial pinch machines built during the 1930’s, 40’s & 50’s and can be found on the used market. All have cast frames as modern alloys and welding techniques had yet to be invented. Double Pinch Plate Rolls are available from light to extremely heavy capacities and may have three or four rolls. The terminology can be confusing as these units may sometimes be referred to as ‘double pinch pyramid plate rolls’ or ‘double initial pinch plate rolls’. Both three and four roll styles have fixed position top rolls and two offset rollers or ‘lateral rolls’, one on each side. The 4 Roll styles have an additional roller directly underneath the top roll, which constantly pinches the plate during rolling. Double Pinch Rolls can pre-bend both ends of the plate without removal as is required with single pinch rolls. Three Roll machines generally require pre-bending the leading end, running the sheet through the machine to pre-bend the trailing end then switching roll rotation direction to roll the cylinder body. Four Roll Plate Rolls have a slight advantage in cycle time since t hey permit pre-bending of the leading edge, rolling the cylinder body and finishing off of the trailing edge all while rolling in the same direction. High volume products can be produced faster when using a four roll machine. Smaller machines can be mechanical but most modern machines are hydraulic and include drop end yokes for easy extraction of the work-piece. Automatic NC or CNC Controls and Four Roll Plate Rolls: Automatic cycle systems are generally used only on four roll plate rolls because there is minimal chance for slippage since the sheet is constantly pinched between the top roll and the 4th roll or “pinching roll”. Automatic controls use an encoder to track movement of the plate through the machine. If the plate slips, the bending roll movements will be out of sync with the material’s translation through the machine. Variable Geometry Three Roll Plate Rolls are not new but are gaining in popularity around the world. They are built for medium, heavy to extremely thick plate applications. The top roll moves up/down and the lower two rolls each move horizontally. This lower roll movement allows increasing the offset distance from the top roll and commensurately increasing mechanical advantage in bending. A machine of this type works well over a wide range of material thickness. By adjusting the geometry they can be used similar to single pinch, double pinch and pyramid style machines and require minimal sheet movement during the pre-bend operations. In the past these machines were commonly found in shipyards but now are being placed in general job shop and manufacturing applications. True Pyramid Machines are not generally manufactured by modern roll builders. They may be found on the used market and are more common in developing countries. They have 3 rolls, both lower rolls fixed in position with the top roll moving up/down. In general they leave very long un-bent flats and have only one or two rolls motorized in rotation. Some special application machines are still produced on a custom build basis and are mostly found in shipyards. They will have the lower two rolls spaced closely together and be of small diameter with midpoint support trunnion rollers. Two Roll Machines are designed for thin or light gauge material rolled to reasonably small diameters. They use a large diameter urethane coated pinch roller which moves up with extreme pressure against a small diameter steel top roller. A mandrel or drum, very close in OD to the desired ID of the part is fitted over the top roll. Two roll sheet rolls are extremely fast and will roll round cylinders or shells even if the blank has large cutouts, voids or holes. Since they require a mandrel for each different part diameter and material thickness they are not as versatile as some other machines. For dedicated high speed production of light gauge cylinders they can be an optimal solution. Vertical Format Plate Rolls can be of nearly any geometry, double pinch, single pinch or pyramid. Vertical rolls are most often used for rolling large diameters and can be advantageous when used in the field for storage tank production. Carell offers automated Vertical Tank Production Systems which are fed from coil stock and can include vertical sheet cutoff and automatic vertical seam welding among other options. These Systems can be used in-house or in the field and increase production output while reducing labor input Optional Equipment and Accessories are offered for most Plate Rolling Machines. The most important items to consider are hardened roll surfaces and cone rolling devices. With today’s harder materials and laser/plasma cutting techniques it is imperative to have a hardened outer surface on the rollers. Look for hardness ratings in the range of 52 to 55 Rockwell C Scale and also for the indication that the hardening process used is “induction hardening”. Hardness in the 52 to 55 RCS range will have a reasonable hardness penetration depth to provide long lasting protection against roll surface wear. Hardness exceeding 58 RCS will have a shallow penetration and a more brittle outer surface which can result in cracking or crazing. Cone rolling devices permit the operator to roll a conical shape and are standard on some machines. Some machine brands require a machine to be pre-disposed at the time of purchase if cones will be rolled in the future. This important point should not be overlooked. Lateral as well as Central Overhead Supports are optional on nearly all Double Pinch Plate Rolling Machines. Some rolls may require pre-disposition for the eventual addition of hydraulic powered supports. Overhead supports prevent lighter materials from collapsing when rolled to large diameters and must be sized according to plate thickness and shell diameter. An overhead support is not a crane and it is designed to sustain nominally only 40 to 60% of the total shell or cylinder weight. A side support can also assist in this function to prevent light materials from re-curving toward the floor if the radius is very large. Some plate rolls are designed with Extended Roll Shafts that protrude through the machine frame at the yoke end. Section or Pipe Dies can be fitted on these ‘stub’ or extended shafts. Some machines are designed with collars inside the machine frame that can be used for profile rolling but when rolling a complete 360 degree hoop it will be impossible to remove from the machine. It is also not possible to coil with inboard collars. It is not practical to anticipate rolling angle iron on a plate roll. Angle will always twist when being rolled. Plate rolls do not have outboard adjustable lateral profile guides to prevent this inherent twist. You should consider using a section rolling machine or double pinch angle roll instead for these applications. In general, section dies on plate rolls are good for bending flat bar the hard way, rods or small pipe. Roll Translation or Roll Movement Up/Down is accomplished either by using inclined linear guides or via swing arms. Direct rectilinear guides direct the thrust of the roll directly toward the top roll and have the fewest moving parts. Rectilinear guides are found on small as well as extremely high capacity rolls. Swing arm designs are not common on large machines and have more moving parts, pins, and bushings. Roll Balancing can be achieved in a variety of methods. Maintaining the bending roll or rolls parallel to the top roll is necessary in order to produce a good true cylinder. Volumetric type and electronic type balancing are the most trouble free for general job shop use. They have up to 80% fewer moving parts than swing arm balancing systems and thus significantly lower maintenance costs in the long run General Note: Roll Bending Machines are very dangerous if used carelessly. It is the responsibility of the owner to ensure the installation and proper use of point of operation safety guards or devices.
