ABSTRACT 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) coveyor line of the pre- sent invention. The conveyor line comprises a pair of con- tinuously 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 open- ings 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.
