摘要： A method and apparatus for transferring a web to a mandrel to form a coreless, convolutely wound roll which includes an enveloping roller, first and second mandrels, a transfer roller and a cutoff mechanism in the path of travel of a web to be wound, advancing a web in partial enveloping relation with the enveloping roller and toward the first mandrel, moving the second mandrel to a position adjacent the web, orienting the enveloping roller and transfer roller to positions defining a pocket with the second mandrel in the pocket to define a nip between the second mandrel and enveloping roller, rotating the transfer roller in a direction opposite to the direction of advance of the web, and severing the web to provide a leading edge portion.

摘要： A method and apparatus for sealing the tail of a convolutely wound log which includes the steps of providing a turret rotatably mounted in a frame and having a plurality of circumferentially spaced apart three-roll clusters, feeding a log into a first cluster while positioning an immediately previously fed log with a draped tail in another cluster adjacent glue apparatus and while ejecting an even earlier fed log now rewound from still another cluster, and providing a log infeed mechanism adjacent the turret and including a pair of relatively movable rollers, feeding logs sequentially into the pair of said rollers, rotating the infeed rollers to orient the log tail in a predetermined position, by providing a mark on said log prior to the feeding step, and detecting said mark to orient the tail in a predetermined position.
