ABSTRACT:
The disclosure concerns a double-drum winder for winding and for then ejecting a wound roll of web material and transferring the same to a delivery table. Adjacent to the double-drums on which the roll is wound there is a transfer table which is movable between a horizontal position where it can receive the wound roll from the double drums and a vertical position where the upstanding table blocks undesired movement of the wound roll past the transfer table. An ejecting device moves the wound roll to the transfer table. The transfer table is on a swivel mount so placed that the transfer table pivots away from the drums as it swivels up from its horizontal to its vertical positions. The swivel axis of the transfer table is on a swivel mount that is supported for limited vertical movement. A lock holds the swivel mount vertically up and it is spring-biased down against the lock. A fluid operated linear actuator moves the transfer table between its horizontal and vertical orientations and also pulls up the swivel mount.
