ABSTRACT:
There is provided an apparatus for wrapping a film around a palletized load, in which the main operative portions are suspended above the load, in order to save space. A central driven shaft extends downwardly from a frame which is supported above the wrapping location, and the shaft supports and rotates a radially extending arm from the distal end of which a downward member extends. A vertically reciprocating carriage mounted on the downward member carries a roll of film, which is dispensed as the roll is carried in a circular path to orbit around the load. Where the width of the film is less than the height of the load, the carriage is reciprocated while orbiting, so that a helical wrapping procedure can be accomplished. A similar but non-reciprocating carriage permits the wrapping to be performed using a film width equal to the height of the load as an alternative embodiment.
