ABSTRACT:
The tail gap winder transfers a web from a first wind-up spindle to a second wind-up spindle by, immediately after the web is cut, pivoting the idler roller to lengthen the distance between the idler roller and the rotating drum to create a gap between the cut ends of the web; moving the first wind-up spindle away from the rotating drum surface as the gap passes under the first wind-up spindle location; moving the second wind-up spindle into contact with the rotating drum surface as the first wind-up spindle moves away; and winding the incoming cut edge around the second wind-up spindle. The idler roller pivots toward the rotating drum to decrease the distance between the idler roller and rotating drum and to take up the extra length of web during the winding portion of the operating cycle.
