  • HRB3V Variable Geometry Roll Diagram

The new HRB 3V variable geometry plate roll come standard with a very capable PLC 7 axis machine controller. This control makes simple the setup and operation of this multi-movement plate roll. The controller not only displays all three roll locations at any one time, it also shows the rotational speed as well as the upper roll rotational speed on the screen, seen as a reproduction of a clock face. X,Y,and Z axis are constantly displayed on the operational screen reporting actual location by the one tenth of a millimeter.

Bending Thicknesses: 1″ – 6″
Variable geometry plate rolls are more versatile than single or double pinch 3 rolls
because of the way they are built. They are suitable for medium and thick plate
Unlike the standard 3-roll, the lower rolls move horizontally to right and left and the
upper roll moves up and down.
Similar to 4-roll machines, the material is loaded parallel to the floor, so putting the
machine in a pit is an option.
The current system design allows the roll to be used as a traditional pressing roll in
addition to standard rolling.
