ABSTRACT:
A punching station for a web includes a web transport system that operates to advance the web in a first direction at a first rate. A clamp intermittently grips a portion of the web to advance the portion in the first direction at a second rate. A punch is coupled to the clamp such that the punch moves in the first direction together with the clamp. A punch block cooperates with the punch. The punch block is coupled to the clamp such that the punch block moves in the first direction in unison with the clamp. A punch actuator causes the punch to penetrate the web and then to be withdrawn from the web while the web is gripped by the clamp.
