Zusammenfassung:	In manufacturing a link plate for a roller chain, a band of sheet steel is intermittently forwarded along a path past series of dies, including rough punching dies and shaving dies. The punching dies and corresponding shaving dies are located symmetrically on opposite sides of an intermediate location along the path. The intermediate location coincides with a location at which the lateral deviation of the band reverses. Consequently, the outer peripheral surfaces of the plate and the inner peripheral surfaces of the connecting pin holes, both being formed by rough punching, are brought into very close alignment with the shaving dies.
