Patent number: 4599131Abstract: A plastic bottle delabeling apparatus in which a series of heated rolls that are driven at increasingly greater peripheral velocity engage the plastic bottles to flatten and stretch the bottles. While flattening the bottles, the apparatus heats the plastic bottle surface by the contact with the heated rolls, effectively softening the bond of any label to the bottle. The flattened bottle is then passed through a pair of opposed rotating brush rolls which strip the loosened label from the bottle. The rolls are in vertically opposed sets with the peripheral velocity of the sets of rolls being successively greater in the direction of movement of the bottles therebetween.Type: GrantFiled: June 10, 1985Date of Patent: July 8, 1986Assignee: Owens-Illinois, Inc.Inventor: John J.
