Abstract: A rotary punch includes an upper die plate, a lower die plate, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway. The lower die plate is connected to the support frame for movement in a linear horizontal direction only. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods attached to the upper die plate that extend down through bushings provided in the lower die plate. In operation, the lower die plate horizontally follows the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper plate moves towards and away from the lower plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

Abstract: A roll forming apparatus includes at least one convertible roller assembly. The convertible roller assembly includes a support plate rotatably mounted on a shaft. The support plate includes at least one roller. The support plate may be toggled by an actuator from a first position for forming C shaped members to a second position for forming Z shaped members.
