Abstract
Abstract A remote controlled apparatus for automatically starting a web winding around a core, comprising a first and second winding drum, a rider roll nipping the core against the winding drums. A pair of plates positionable into contact with the rider roll and the winding drums, thereby enclosing the pocket between said winding drums and said rider roll. A web holding means located underneath the winding drums and engageable with the first winding drum, thereby preventing the leading end of a severed web from falling down between the winding drums. With the web nipped between the first winding drum and the core, the first plate diverts the web into the nip between the rider roll and the core, passing through the nip, the second plate diverts the web into the nip between the second winding drum and the core, passing through the nip, the web holding means diverts the web upward into the nip between the first winding drum and the core, thereby completing one full web wrap about the core and the web winding thereon, without the use of adhesives on the core.
