ABSTRACT:
A roll former line for forming different shapes including a first roll stand attached to a bed which provides vertical adjustable movement. The roll stand includes three spindles in vertical alignment with each other, the forming rolls on the top and bottom spindles working against opposite sides of the middle forming roll, so as to provide reverse shapes between the top and middle forming roll and the middle and bottom forming roll. Linear actuators are connected to the bed of the first roll stand for moving the first roll stand vertically on the bed. Opposite the first roll stand on the line is a second roll stand attached to a second bed including two spindles in vertical alignment and corresponding forming rolls thereon. The first roll stand can be raised or lowered by the linear actuators so as to use reverse forming rolls on the first roll stand in conjunction with the forming rolls on the second roll stand to form a reverse shape on one edge of the sheet being formed.
