ABSTRACT:
A tape applying apparatus (10) includes a plurality of pairs of vacuum heads (120, 122) extending axially at circumferentially spaced intervals on a disc (24) rotated about an axis by the extension of a cylinder (48) which is operatively connected by a cam follower (60) to a cam (40) rotatably fixed to the disc (24). The vacuum head (120) adjacent the free end of the tape includes a trough (126) including vacuum bleed holes (128) for drawing the tape segment extending over the trough (126) into the trough (126) to form a tab when desired. A slide (66) is reciprocated between retracted and extended positions by a further cylinder (72). A knife (98) is movably connected to the slide (66) for cutting the tape when the knife (98) reaches a cutting position, with the knife (98) stopping at the cutting position before the slide (66) reaches the extended position. The first ends of first and second arms (74) are pivotably mounted to the slide (66) about spaced pivot axes (76), and rollers (78) are rotatably mounted to the second ends of the arms (74). In the retracted position, the rollers (78) are spaced from the tape segment removably held by the last pair of vacuum heads (120, 122) and from the carton. As the slide (66) moves towards the extended position, the rollers (78) engage the tape and sandwich it against the carton and then roll on the sides of the corner to adhere the tape segment to the corner, with the tape segment being cut and then pulled from the vacuum heads (120, 122) after the rollers (78) are in their engagement position.
