Suitable for rolling thin, medium-thick aluminum plates or stainless steel plates. Any cylinders in full circle or in varying radiuses can be done easily.
Initial Pinch Plate Rolls PRA
PRA 3 roll initial pinch plate rolls generally are for light-capacity applications and are electromechanical or hydraulic, they ensure you get excellent results with a single operator thanks to their ease of use feature, with a familiar asymmetrical construction, providing a simple and inexpensive approach for thin sheet metal bends.
The PRA 3-roll plate bending machine is the best solution for bending plates with thicknesses between 1 mm and 9 mm and widths from 1000 mm to 3000 mm.
The PBA Initial Pinch Plate Rolls work by pinching the metal plate between two vertically opposed rolls while the third bending roll—moves upward to contact and then bends the plate. When the rotation of the rollers is activated, the plate 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 shape that can then be welded at the seam to produce a closed cylinder.
