Abstract
Erected cartons are fed downstream on a dead plate by the various flight bars of a flight bar conveyor system, and between upper and lower pairs of side guides which are adjustable both laterally to accommodate cartons of various widths. Plows associated with the side guides preposition the closure flaps of the cartons so that each of these flaps is received in a slot of an adhesive applying head so that bands or strips of adhesive are applied to these flaps. The adhesive applying heads are uniquely mounted in that they are conveniently prepositioned for accommodating the flaps when the side guides are adjusted to the width of the carton. Two such heads are pivotally mounted in a block provided on the longitudinal center line of the machine, with a link being provided between each adhesive applying head and the side guide structure. In one version this link is slidably received in its associated adhesive applying head so as to permit movement of the head along the link in order to automatically vary the angle of the head to accommodate cartons of various widths.
