ABSTRACT:
A wrapping machine for wrapping a palletized load is provided with a film carriage having a spool of film. A means for unwinding the film from the spool from an upstream winding position to a downstream position in accordance with a selected path where it is applied to the load is also provided. Prestretching rollers for prestretching the film before it is applied to the load are contained on the film carriage. Cutting blades are used to pierce the film, downstream of the prestretching rollers, into longitudinally extending strips. The strips are then separated into longitudinally extending bands by a separating roller. The bands are applied to a load by the carriage which slidably moves up and down along a support column in combination with a turntable upon which the load rotates.
