Abstract: A bending apparatus for corrugating a sheet-like material can comprise a support member, a feed mechanism, a bending member, a hold-down member, and a driving mechanism. The support member can comprise a support surface with corrugations. The feed mechanism can be configured to feed the support member in increments of one pitch of the support member corrugations. The bending member can be configured to reciprocate between a retracted position and an actuated position mating with a corrugation on the support surface so material laying on the support surface is bent along the support member corrugation. The hold-down member can be configured to be reciprocated between a retracted position and an actuated position holding the material against the support surface. The drive mechanism can be configured to sequentially reciprocate the bending member and the hold-down member so the hold-down member presses down the material and the bending member bends the material.

Abstract: A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die 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 pressing tool having a drive unit, a piston-cylinder unit with a fork-like receiver and an actual clamping pincer. The clamping pincer has a T-shaped mounting which, with a retaining bolt and a retaining bolt receiver, is connected to a fork-like receiver. In the fork-like receiver, a roller holder with two rollers is located. The fork-like receiver is part of the piston-cylinder unit. On actuation of the pressing tool, the piston-cylinder unit is pulled back and thus the roller holder with the rollers is moved forward relative thereto in an axial direction towards the clamping pincer. Thus, the rollers roll on roll flanks of the clamping jaws of the clamping pincer. The clamping pincer is pressed together by the rollers pressing apart the clamping jaws at the rear. Thus, the rollers are supported on a bearing block with sliding bearing surfaces.

Abstract: A portable cam and lever actuated press which utilizes the substantial force available from an air spring to actuate one or more lever arms. The substantial force available from an air spring and the specialty cam system provided allows the device to perform clinching, crimping, punching, stenciling, riveting, stamping, holding, or other operations which would normally be performed with much larger and heavier equipment when the proper punches and dies are installed onto the lever arms. The unit operates pneumatically without the need for hydraulics or hydraulically assisted components.
