ABSTRACT:
An apparatus for folding and filling a plurality of cartons erected from a plurality of collapsed carton tubes includes an end flap alignment device attached to the conveying and folding mechanism of the apparatus. The end flap alignment device folds one of the bottom end flaps of the collapsed carton tube inwardly and in the same motion folds the top end flap which is also provided on the bottom of the carton tube outwardly so that the bottom end flap and the top end flap are aligned in the same plane. The end flap alignment device comprises a generally U-shaped fork comprising a base attached to a plate and two rods each connected at one end thereof to the base. The plate is attached to a reciprocable slide of the apparatus by a pivot rod. One end of the pivot rod is connected to a cam, which rides in a cam track. As the slide is reciprocated, the plate, including fork, is pivoted about the pivot rod. By this motion, the fork aligns the bottom end flap and the top end flap of the bottom of the carton tube in the same plane so that glue may be applied thereto in one motion.
