  • Patent number: 8141809
    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.

    Abstract: An apparatus and method of winding a continuously moving web, and for splicing and transferring the web from a first core to a second core with no-fold-back or wrinkling of the web material during the splice. The web is fed through a first nip point and thereby applied to a lay-on roll, the lay-on roll further applying the web material onto first and second cores alternatively. An electrostatic charging bar positioned downstream from the nip point emits an electrostatic charge onto the web to temporarily adhere the web to the lay-on roll. A rotatable cutting knife cooperatively engageable with the lay-on roll cuts the web at a point downstream from the electrostatic charging bar but upstream from the first and second cores to produce a tail and new leading edge. The tail continues to be wound about the first roll, and the new leading edge is affixed to the second roll and the web is thereafter wound about the second core.
