Abstract
An apparatus for a wrapping machine in which a length of packing material is wound around a cylindrical object, especially a roll of paper, said apparatus comprising endless members, such as belts or cords, led over rollers, said endless members being in contact with the applied length of packing material in the circumferential direction of the roll during winding and serving to tighten the length of packing material around the cylindrical object. Three endless members are positioned consecutively in the circumferential direction of the cylindrical object and guided over rollers, said endless members being springbiased to lie against the length of packing material, the inner side of the outwardly-facing running section of the middle endless member passing over a stationary roller, and the breast rollers for all of the endless members being supported by arms in a power-operated pivotal arm system having a common, stationary pivot point on a line through the center of the cylindrical object and the center of the stationary roller.
