ABSTRACT:
Apparatus and methods for winding an element on a pair of rotatable axially aligned drums and discharging the element therefrom between an element supply and an element processing unit. A pair of switch stations are located such that the element received from its supply and being discharged to the processing unit lie in axial alignment. The first station discharges the element onto a freely rotatable drum mounted on a rotatable element. A second axially spaced, freely rotatable drum is mounted on the element for discharging the element to the second station. Between the drums and carried for rotation with the member are a receipt and delivery station carrying a pair of rollers, respectively, overlying the first and second drums. The first and second stations are movable in an axial direction away from one another when the device winds more of the element onto the drums than discharge therefrom and are movable toward one another when the drums discharge more of the element therefrom than being wound thereon.
