ABSTRACT:
A preferred embodiment of a corrugated carton sealing apparatus 10 is illustrated in the Figs. having tape application heads 32 and 34 for applying adhesive tape strips 36 to the top and bottom surfaces of the carton to seal the carton. Each of the tape application heads 32 and 34 have a leading application roller 62 and a trailing application roller 68 that are moved in unison with each other from extended positions as illustrated in FIGS. 1 and 2, to retracted positions as illustrated in FIGS. 4 and 5. The leading application roller 62 travels in a path shown by the curve illustrated in FIG. 7 to apply pressure to a beginning leading edge 38 of the tape to firmly affix the tape edge 38 to the leading surface 14 of the carton. The tape application head 32 includes a tape feed 84 for feeding adhesive tape through the tape application head for application to the container. The tape feed 84 includes a tape stop means 86 that is responsive to the movement of the rollers 62 and 68 between their extended positions and their retracted positions in which the tape stop means 86 automatically prevents further feeding of the tape through the tape application head when the rollers move from their retracted positions to their extended positions.
