Abstract

A punch press is provided with a tool bearing a workpiece-deforming roller, the tool being received in an aperture in the press for movement between a lower position in which the roller comes into deforming contact with a workpiece supported on a surface and a raised position out of deforming contact with the workpiece. Elongated deformations may be formed in a workpiece by translating the workpiece horizontally along the surface while the roller is in its lower position. A coacting roller may be provided beneath the workpiece so that the rollers come into deforming contact with opposite sides of the workpiece to deform it as the workpiece is translated between the rollers.
