Abstract
A winder for winding process webs on roll cores may include a first winding position configured for rotatably securing a first roll core and rotating the first roll core in a first rotational direction. The winder may also include a second winding position configured for rotatably securing a second roll core parallel to the first roll core and rotating the second roll core in the first rotational direction. The winder may also include a roll positioning assembly configured to move a portion of the web upstream of the second winding position from a first side of the first winding position to a second side of the first winding position.
