Apparatus for applying tape to a forwardly traveling carton includes a first projecting tape applicator which lies in the path of carton travel. As the carton strikes the first applicator, tape is applied to the carton front panel, the traveling carton depressing the applicator to allow it to apply and wipe tape around the corner formed by the front panel and onto a horizontal panel. A push finger carried on the tape applicator engages for a time with a tape cutter. On engagement of the push finger with a cam near completion of unit depression travel, the finger disengages the cutter and releases it to sever a tape length from the tape supply. A roller in the depressed applicator unit wipes the severed tape length along the horizontal panel for the length that the tape extends along the panel. A second tape applicator unit which moves from projecting to depressed position in tandem with the first unit is located downstream of the first applicator. As the traveling carton moves beyond the first applicator, the depression constraint releases so that the second unit tends to project, and tape from a second supply roll is applied to the carton horizontal panel a distance spaced from where the first tape length ends. This last applied tape is applied around the corner formed by the carton's horizontal and rear panels. A second cutter severs this second tape length from its supply with roller means employed to wipe tape against the carton horizontal and rear panels. |
