Abstract:
A reciprocable feeder arm (10) includes a projecting portion (12) for engaging an edge of a collapsed carton (C) in a hopper (1) and with the aid of a suction cup (13) removes the collapsed carton (C) from the hopper (1) and into a position adjacent but spaced from fixed suction cup means (3) into engagement with which one side wall (A1) of the carton is driven by movable suction cup means (4) which engages the opposite side wall (A) of the carton so that subsequent movement of the movable suction cup means (4) away from the fixed suction cup means (3) moves the carton side walls apart and tends to manipulate the carton into set-up condition during which movement a pair of spaced guides (6) engage end wall panels (B,D,B1,D1) at each end of the carrier and aid further in setting the carrier up while an arcuate fixed guide (6a) disposed adjacent the path of movement of the carton engages its bottom wall (E) so as to hold a pair of end flaps (F,G) foldably joined to the ends of the bottom wall are moved into approximately coplanar relation with the bottom wall so that a pair of fixed adhesive applicators (7) may apply adhesive to the inner surfaces of the end flaps (F,G) following which movement a reciprocable pusher element (8) engages the set-up carton (C4) along its upper edges and moves the carton between a pair of spaced plates (9) which engage the carton end flaps and force such flaps (F,G) into firm flat face contacting engagement with the end panels (B,D,B1,D1) at each end of the carton.
