Abstract: A carton flap hold down apparatus (25) for use in seating an open-ended sleeve-type carton (40) on a carton transport conveyor (27) is disclosed. The carton flap hold down apparatus has a plurality of aligned carton flap hold down rollers (61) disposed along a common longitudinal axis and extending in the direction of a path of travel, each support roller being supported for rotation on an elongate roller support bar (65). A mounting block (67) is fastened on a framework of the carton transport conveyor with respect to a carton flap score rail (31) thereof, the mounting block being spaced from the roller support bar, and an elongate intermediate member (66) is fastened to one end of the mounting block, and fastened at the other of its ends to the roller support bar. The rollers are inclined toward the mounting block in the direction of the path of travel at an angle of 5.degree.

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.
