ABSTRACT:
An apparatus is provided for handling a web of material fed from a roll. When the roll is larger than a selected amount, a roll contacting belt contacts the outer surface of the roll to aid in rotating the roll. The roll contacting belt is speed-responsive to a tension sensing means. Once the roll decreases to the selected amount, the roll contacting belt is disengaged from the roll and a positive drive controls the speed of the roll. This arrangement reduces web upsets caused by out of round new large rolls and eliminates telescoping due to the action of the belt against small diameter rolls.
