4 Roll

Our 4 roll plate roller machines are advanced bending and rolling machines as they are more precise, productive, versatile, faster, safer and easier to operate than our three roll machines as they are less dependent on operator competence. They are ideal for rolling metal plate from 10 gauge steel all the way up to up to whopping 6” thick metal plates. The fastest and most accurate bends are made on our four roll plate rollers. The plate is held securely in place between the top and bottom induction hardened rolls while the side rolls move vertically to create an accurate bend easily, intuitively and quickly. All of our 4 roll plate rolling machines can roll sheet metal as fast as 21 feet per minute, bringing you the most high-tech in high productive mid range to heavy plate rollers on the market. SANCO is proud to say that all of the plate roller machines we produce are high quality production machines that comply with the tight ISO 9001:2008 certification standards which are a MUST in today’s competitive environments.

Why Should You Consider A 4 Roll Plate Roller Over A 3 Roll Machine? 

    With our 4 roll machines the bottom roll moves up to hold the plate edge securely against the top roll while the side roll is raised to form an accurate pre-bend, minimizing the flat zone on the plate edge. Pre-bending on a three roll machine requires that plates be tilted down as they are being fed. In contrast, plates are loaded horizontally at the feed level for pre-bending on our four roll machine, which allows the use of horizontal motorized roller tables to help feed the plate. Plate feeding can take place on either side of our four roll machine. If fed from only one side, they can even be placed up against a wall to save floor space. The side rolls are positioned to the right and left of the bottom roll and are on their own axes. The independent axis of each roll helps make a perfect bend. The “back” side roll (at the far side of the feeding point) also functions as a back gauge to square the plate for proper alignment. This eliminates the need for someone to assist the operator. The plate is kept square without slipping during both pre-bending and rolling because of the constant secure clamping of the top and bottom rolls.

 

4 Roll Plate Rollers Create A Greater ROI With Efficiency And Time Savings!

   The four-roller does not need to be disassembled by the operator, flip, and then try to square and re-position the plate a second time after pre-bending, as is the case with three roll initial pinch roller machines. Being able to keep the material in the machine makes our four roll machines 50% more efficient than three roll initial pinch machines, and allows a cylinder to be rolled to the required diameter immediately following pre-bending. Bending the back edge takes place after the cylinder is rolled, for a one direction, single pass operation.

 

Roll Cones With Ease With Our 4 Roll Plate Roller Machine! 

   Cone rolling is easier on a four roll machine. The side rolls can be tilted to establish the cone angle and the bottom roll can also be tilted to clamp and drive the plate. Plate rolls with rollers 17 inch in diameter or smaller are designed to utilize planetary guides. Plate rolls with rollers larger than 17" diameter are controlled by rectilinear guides that provide the controlled movement required to create accurate bends and this design increases the longevity of the machines life. This system allows bending of as small as 1.1 times the diameter of the top roll, providing the tightest bend radius in the industry. Through superior construction and design, a massive heavy weight body and the ability to angle bottom and side rolls our 4 roll plate roller can bend wide angle and small diameter conical parts with ease, with minimal effort from the operator. While most machines on the market can conically bend three times the diameter of the top roll, ours can conically bend 1.5 times the diameter of the top roll and frequently smaller diameters than that.
