ABSTRACT:
In a machine for sealing forwardly traveling cartons with adhering tape lapping folded stacked flaps as top and/or bottom closure means to prevent normally projecting tape applicator means from applying to such closure means of each carton excessive inward pressure which may cause such deflection thereof as to catch into and break back out an edge portion of the carton back end wall. Movable mounted tape applicator means is projectable into a defined path of forward travel of a folded stacked flap closure of an advancing carton for depression by the latter as it travels forwad thereover for application of tape to such forwadly traveling closure. Mechanism that is alternately projectable and depressible of the tape applicator means is located initially in the path of forward travel of each such carton for depressive manipulation of this projecting applicator means upon contact by the advancing carton. Releasable latch means which is manipulated by that mechanism is provided to hold the tape applicator means depressed while the advancing carton and its closure are traveling past the tape applicator means. There is also provided means to release the latch means for restoring the projection of the tape applicator means into the carton travel path after passage of this carton.
