Abstract
An apparatus for winding a flexible web continuously moving in a longitudinal travel direction as rolls onto sleeves has a winding station for holding a sleeve and rotating it about an axis for winding the web onto the sleeve. Upstream of the winding station at a changeover station a fresh sleeve is held adjacent the continuously moving web. A shell juxtaposed with the fresh sleeve in the changeover station forms therewith a gap. A cross-cutter for the web is provided adjacent an end of the gap and can form on the web a trailing end and a leading end so that the trailing end travels to the winding station for winding on the sleeve therein. Air is drawn air into the end of the gap to aspirate the leading end into the gap. This leading end is electrostatically adhered to the fresh sleeve in the changeover station.
