An apparatus for forming a shipping and display box of the type having diverter tabs that extend outwardly from the box walls is provided that has a guide plate for supporting a blank used for forming the shipping and display box, a catcher plate used for holding the blank on the forming apparatus, a diverter tab lever for extending the diverter tabs outwardly from the box walls, and an actuator for urging the diverter tab lever against the diverter tabs, the actuator allows the catcher plate to be released after the diverter tabs have been extended from the box walls so that the blank can be removed from the forming apparatus. A method of forming the blank into the shipping and display box is also described.

Shipping and display box former

Apparatus for continuously feeding and controlling wraparound carrier for packaging a plurality of articles or containers is disclosed. The carriers are of the type having at least two draw-down and feed openings, one opening formed on each side thereof. Each carrier is initially partially wrapped about a plurality of containers. The carrier and container assemblies move along a guide track to the entrance of the carton draw-down (tightening) conveyor line of the present invention. The conveyor line comprises a pair of continuously moving timing chains having a plurality of draw-down lugs pivotally attached to and spaced apart along the chain. Each lug includes a tongue portion adapted for insertion through the openings to feed and to draw down the side walls, and also to control the positioning and movement of the containers. As the partially assembled carrier and containers enter between the moving chains, a cam follower portion of the lugs contact the camming rails, causing the lugs to sequentially pivot downwardly and into contact with the openings formed in the carrier. The carrier is moved along the conveyor line with the lugs engaging the containers through the carrier apertures for positive control. Downward pressure is applied by the lugs to the carrier, causing the carrier to be pulled down and tightened about the containers. The lugs are pivoted out of contact with the carrier as the carrier exits the conveyor line to complete the assembly process.
