ABSTRACT:
A tape perforating head assembly for scoring a perforated tear line in a piece of packaging tape joining article carriers together includes a headpiece, a plurality of perforating blades supported on the headpiece parallel to and adjacent one another, each perforating blade having a series of serrated teeth constructed and arranged to score the perforated tear line in the packaging tape. Each perforating blade is supported on the headpiece for reciprocal movement with respect to one another into a normally extended position away from the headpiece, and into a retracted position on the headpiece. The tape perforating head assembly also includes a spring positioned within a bore in which a guide pin is received, a pair of guide pins, and a pair of bores being provided for each perforating blade. The tape perforating head assembly scores a perforated tear line in the packaging tape by moving the headpiece in timed relationship with the movement of the carrier along a path of travel extending through a packaging machine, moving the perforating blades into contact with the packaging tape, and scoring the perforated tear line in the packaging tape with at least one of the perforating blades as the carriers move along the path of travel.
