Abstract

In a method and apparatus for automatically feeding sleeves in roll cutting machines of the support roller type, a wide web (12) of paper or the like is unwound at an unwinding station (10). At a cutting station (20) the wide web (12) is slit lengthwise into at least two narrower, partial-width webs (24). The narrower, partial-width webs (24) are wound up using winding sleeves (44, 54) at two winding stations (40, 50) arranged either side of the support roller(s) (30) and each comprising at least one winding device (41, 51) so that adjacent partial-width webs (24) are wound at different winding stations (40, 50 respectively). The winding sleeves (44, 54) are pushed in a feeding device (60) into a transfer position oriented parallel to the support roll or rollers (30) in a row one after the other in order to the winding devices to be loaded, distributed from their transfer positions to both sides of the support roller(s) and transported to the loading positions in the winding devices (41, 51), in order to be loaded there for the purpose of later receiving their partial-width webs. The winding sleeves (44, 54) which are in their transfer positions and distributed to both sides of the…
