ABSTRACT:
In the manufacture of a link plate for a silent chain, a band of sheet steel is intermittently forwarded to string of punching dies and shaving dies. The band tends to follow a slightly curved path, which causes alignment errors in a conventional punching and shaving operation. However, in this case, each shaving die and its corresponding punching die are disposed in symmetrical relationship with respect to an intermediate position along the path of movement of the band, and the intermediate position coincides with the location at which the deviation of the band. As a result, the shaving dies are more accurately aligned with the punched surfaces produced by the corresponding punching dies.
