ABSTRACT:
An apparatus is useful for wrapping a wrapping film over an elongate load, which has a generally cylindrical exterior and two generally circular or generally annular ends. Two blocker rollers cradle the load with its axis extending horizontally and are arranged for rotating the load about the load axis. A dispenser mounts a roll of the wrapping film with its axis extending vertically. The dispenser is mounted on a rotatable arm, which is rotatable about a vertical axis. A carriage is provided for mounting the dispenser and for carrying the dispenser and the roll back and forth along the cradled load. Thus, the roll is moved along an oblong path, whereby the film pulled from the roll is wrapped over the near side of the load, one end of the load, the far side of the load, and the other end of the load, as the load is rotated. The roll remains at an elevation above a central portion of the load so as to permit the central portion to remain unwrapped.
