Work Principle of PRA Pre Pinching Plate Rolling Machine

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.
