Plate Roller Machines

Plate rolls are the ideal machine for metal sheet pre-bending and rolling. A plate rolling machine creates a mechanical advantage by pressing a metal sheet between a top roll and two side rolls. The mechanical advantage allows the machine to press the sheet firmly against the rolls, bending it into a conical or spherical shape. Throughout the process, a pinch roll is typically used to hold the metal plate in the correct position.

There are two types of plate bending processes. Static pre-bending is where the metal sheet is held stationary while a roll runs upward along the sheet, bending the leading edge. Dynamic bending, on the other hand, is where the plate or sheet is in motion while running through the machine. The motion of the sheet allows the machine to work more efficiently, thus increasing the sheet bending thickness.

Plate rolling machines are extremely powerful and able to bend metal sheets of varying thicknesses (typically between ½ to 2 inches). Plate rolls come in 3-roll or 4-roll models. 4-roll models are nearly always CNC automated and specifically designed for large-scale, high-volume plate bending needs.
