ABSTRACT:
A mechanism for folding end tabs over and against the end walls of a partially completed carton. The mechanism is designed to handle cartons of two different lengths fed at random through the machine. It includes kicker elements to inwardly compress the carton and its contents so as to assure proper final carton formation when the end tabs are sealed. The end tabs are folded and sealed while the carton moves continuously along a longitudinal path. They are folded by transverse folding elements mounted across the working flight of an upper conveyor assembly along the carton path. Each tab is folded and sealed against the respective carton end walls as the carton progresses between the infeed and discharge ends of the conveyor assembly. Selected folding elements are activated dependent upon the length of a particular carton being handled.
