Method and apparatus for placing inner headers onto the ends of paper rolls

Abstract

A method and apparatus for placing headers onto the ends of paper or paperboard rolls by inserting the headers into the tubular cavity formed by the overlapping rim of the roll wrapper to the roll end. The roll to be packaged is transferred to the header inserter station, a header of desired type for the roll is fetched from a header support shelf and delivered to a header inserter grabber of a header inserter assembly waiting in its delivery position. Next, the header is transferred by movement of the header inserter grabber into the tube formed by the wrapper overlap, and subsequently, the header is transferred against the end of the roll. The header is transferred into the wrapper tube by means of rotating the header inserter grabber about a shaft, which is offset from the transfer path of the roll and is aligned orthogonal to the longitudinal axis of the roll. The header is made to advance into the wrapper tube in a tilted position so that the edge of the header situated closer to the shaft enters the wrapper tube before the entry of the trailing edge of the header into the same.
