ABSTRACT:
A machine for continuously punching, shearing and forming sheet material comprises a frame and punching, shearing, and forming stations. Rollers are provided for continuously feeding sheet material through the stations. A cam periodically engages the tools of the respective punching and shearing stations to actuate the respective punching and shearing operations and simultaneously to advance the respective punching and shearing stations in unison with the direction of feed of the sheet material. The forming station includes adjustable rollers which permit adjustment of the space between the rollers. The method of the present invention comprises continuously feeding the sheet material through the punching, shearing, and forming stations. At the punching and shearing stations, the tools for punching and shearing the sheet material move in unison with the sheet material during the time that they are performing their punching and shearing operations, respectively.
