is aligned with the actuator 38 because the first punch 14 is retracted the linear actuator 38 is capable of sliding the key 36 between the first position of the key 36 and the second position of the key 36 the actuator 38 is also capable at all positions of the punch 14 of pivoting the catch 30 between its non engaged position and its engaged position a guiding member 40 for receipt of the key 36 is located on the linear actuator 38 a guided member 42 is on the key 36 the guiding member 40 includes a funnel or cone shaped guide for alignment of the key 36 into contact with the linear actuator 38 as the first punch 14 and the punch block 22 move away from the direction of primary punch motion i e the direction of retraction the guided member 42 docks against and into the guiding member 40 thus the guided member 42 becomes docked on retraction and is guided by the key 36 while docked for transverse motion both punches 14 16 operate simultaneously when the key 36 is in the first position limiting movement of the second punch relative to the punch block member 22 and the catch 30 is in the non engaged position the.
