Abstract
A bag machine includes a hole forming apparatus with a pair of adjustably mounted hole punches and a wicketing apparatus including a pair of wicket pins. Both the punches and pins are separately adjustably mounted on a slide mechanism for establishing corresponding location in spacing of the punched holes in the receiving wicket pins. Each slide mechanism or assembly includes fixed elongated track having equi-spaced locking elements in the form of spaced recesses in the base of the track. The recesses are equi-spaced. A separate slide element is provided for each of the paired devices for adjustably mounting of the device on the related track. Each slide includes a spring loaded detent plunger aligned with the series of locking recesses. The punch slides are located in alignment with the recesses on the punched track and the plunger released to lock the punches in predetermined hole spacing. The wicket pins are correspondingly adjusted to locate the wicketing pins of each stack unit with corresponding hole-to-hole spacing. In each slide assembly, a single pair of simple detent units control the proper spacing of the punches and the pins.
