ABSTRACT:
Apparatus for adhesively bonding a clam-shell type carton formed from a paperboard blank includes a carton forming die for receiving the paperboard blank, a movable frame for transferring the carton blank from a stack into registration over the die and a reciprocating plunger mounted above the die for forcing the carton blank into the die to fold and erect the carton. The movable frame includes a number of vacuum assisted suction cups for lifting the carton blank from the stack and a plurality of spring-loaded adhesive applicators, connected to a pressurized source of adhesive, for applying a spot of adhesive to selected portions of the carton blank when the blank, carried by the movable frame, is pressed into registration over the forming die. A stacking cage is disposed beneath the carton forming die to receive and retain the erected and folded cartons in a vertically stacked, nested arrangement, with adjacent cartons bearing against one another so that the adhesive coated portions of each nested carton are retained in contact with adjacent panels of the carton for a time sufficient to allow an adhesive bond to form therebetween.
