Abstract: A packaging tape applicator for automatically applying packaging tape to groups of juxtaposed containers travelling along a conveyor comprises a gate mechanism movable between a holding position and a delivery position, for apportioning a continuous supply of individual containers into consecutive groups. Indexing means move along the conveyor in synchronized relation to the gate mechanism such that the indexing means are disposed in separating relation one between each consecutive pair of groups of juxtaposed containers. First and second packaging tape applicator mechanisms are positioned on opposite sides of the packaging tape applicator to apply first and second lengths of packaging tape to the groups of juxtaposed containers. First and second cutting mechanisms move in synchronized relation to the indexing means to cut the packaging tape, thereby separating the taped groups of juxtaposed containers one from another.
