ABSTRACT:
To cinch a web end portion onto a web-free core, the core is driven by a core drive mechanism at an outer surface speed in excess of the speed at which the web end portion is fed to and threaded around the core. The core drive mechanism slips but continues to drive the core after the web end portion is cinched onto the core. After the web is wound to form a roll of predetermined diameter, the core drive mechanism is disengaged from the core to terminate the core drive. The outer surface of the partially built up roll further substantially simultaneously engages a builder roller which surface drives the roll.
The core drive mechanism further comprises a gudgeon for engaging and rotatably driving the core, and a rotatably mounted drive wheel which is driven by the builder roller. The drive wheel is coupled to the gudgeon by a bearing for driving the web-free core at an outer core surface speed greater than the web speed.
