ABSTRACT:
Method and apparatus adapted for use on a conveyor line to form a rolled tab in the tail end portion of a roll of plastic film wound on a core. The tail end portion initially extends around the surface of the roll to which the tail end portion adheres and terminates at a tail edge. The apparatus includes a bucket which is connected to the conveyor line for movement thereon and has a floor and wall extending therefrom. The floor of the bucket has a tractional surface supporting the roll and the wall has a substantially frictionless surface pushing the roll in the direction of the conveyor line. The apparatus further includes a drive, extending in stationary position substantially parallel to the conveyor line and having a resilient tractional surface being compressed into rotational contact with the roll, for rotating the roll. The drive rotates the roll to rub the surface of the roll against the tractional surface of the floor which separates the tail end portion from the surface of the roll and rolls the tail edge back on the tail end portion to form a rolled tab containing the tail edge.
