ABSTRACT:
Apparatus for transferring a web moving in a guided and supported web feeding course traversing around a rotary frame and passing therefrom to and winding as a web stock on a first core at a winding station proximal a rotary frame periphery is provided with a rotary circular cutter on the rotary frame that cuts the moving web crosswise of the web travel. Prior to cutting the web the first core is moved away from the winding station and replaced thereat with an empty takeup core. The rotary frame is then rotationally speeded up so that its periphery at which a frame carried web contact shoe and rotary cutter can be positioned move in tandem with the web. The web contact shoe can then be brought into contact with the web to hold it and the circular cutter is operated to cut the feeding web. A trailing end of a part of the web downstream of the cut continues on to windup on the first core. A leading end of the part of the web upstream remains held by the contact shoe. The contact shoe following web cutting is stroked outwardly slightly of the rotary frame periphery so that as the contact shoe passes proximal a periphery of the empty core, the leading end of the web contacts the empty core periphery and starts to wind on the core periphery, this thereby accomplishing transfer of the feeding web to the core winding operation.
