ABSTRACT:
A winder for winding pliable material into coreless rolls includes a conveyor for bringing the material into proximity with a turret. The turret includes a plurality of spindles upon which the material is to be wound. Transfer of the material to the spindle is accomplished by a cluster of rollers which surround an individual spindle at the time of transfer. Ropes or belts pass around the rollers to assist in guiding the pliable material. An air blast also assists in the transfer. At least one of the rollers is pivotable from a first position to a second position. An empty spindle is brought into the transfer position during turret indexing. The system of the present invention also includes a collapsible spindle to facilitate removal of the finished roll. The diameter of the spindle is decreased as a push-off palm removes the roll from the spindle and is increased during retraction of the palm to prepare the spindle for attachment of the leading edge of the next roll.
