Abstract
A blank for forming a wrap-around carton is delivered to a moving support carriage which is moved to a station where the moving carriage receives a predetermined number of articles to be packaged. The carriage, with the articles resting on the bottom portion of the blank, is moved downstream while cams actuate tucker fingers which pivot up to fold the tuck flaps of the blank toward each other, causing the end and side panels to be elevated. Another cam actuates a pusher bar which pivots up to push the articles. The carton blank and the articles are thus positively moved through subsequent flap folding and gluing stations, avoiding the problems which can arise due to the use of separate means for moving the articles and the carton blank. A cam operated hinged plate is used to segregate the leading articles at the entry to the machine.
