ABSTRACT:
A continuous winder for web material includes two pairs of turret arms mounted for rotation with respect to each other on a common axis, and also includes a lay-on roll mounted for lateral movement toward and away from the axis of the turret arms. The lay-on roll maintains pressure engagement with the winding roll until the interval of actual roll changing, when it moves from the wound roll into pressure engagement with the new core with the web running therebetween, whereupon the web is cut between the two rolls to complete the roll change. The knife assembly for cutting the web is carried by another pair of pivotally mounted arms and includes a clamp mechanism on each arm which effects rotatable clamping engagement with the adjacent turret arm carrying the new core so that the knife arms and the core-carrying turret arms travel together throughout the actual operation of roll changing and thereby assure that the knife is held in proper relation with the core before the roll change is made and while it is being made.
