发明名称 METHOD AND APPARATUS FOR WINDING CORELESS ROLLS
摘要 A method and apparatus for transferring a web (W) to a mandrel to form a coreless, convolutely wound roll which includes an enveloping roller (28), first and second mandrels (29, 30), a transfer roller (40) and a cutoff mechanism (36, 37) 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 (50) with the second mandrel in the pocket to define a nip between the second mandrel and enveloping roller, applying a steady force to the web downstream of the second mandrel by 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.
