  • Patent number: 4821973
    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 core brake 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. In the illustrative form of the invention, the apparatus provides a continuous supply of web material by handling a first roll from which web material is being fed through an infeed roller and a nip roller, and a second roll from which web material is fed after the web material of the first roll has expired.

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.
