ABSTRACT:
Folded and tied newspapers are delivered in a stream to an infeed conveyor which moves the newspapers in succession toward an inserting station where a stack of flimsy plastic bags are waiting. Just prior to reaching the inserting station, the newspaper is gripped by high-speed accelerating rollers which fire the newspaper into the open mouth of the inflated top bag in the stack. High-speed ejector rollers then clamp onto the bagged newspaper and pull it off the holding wicket for movement on down the line. A special, transverse, bag supply shuttle has two separate bag holding zones along its length so that one zone containing an adequate supply of bags may be presented to the inserting station while the other, empty zone is restocked with a new supply. During shifting of the shuttle, the incoming stream of newspapers is diverted temporarily so that no newspapers are presented to the inserting station during manipulation of the shuttle.
