Wrapped cotton bales transported from a cotton harvest area to a receiver at the gin are moved intact to a position generally above a receiver upstream of the ginning equipment. As the bales are supported and conveyed, knife or similar cutting structure severs a portion of the wrap allowing egress of the cotton from the wrap into the receiver. Wrap removal structure prevents the wrap from entering the ginning equipment. In one embodiment of the invention, the wrap is conveyed to a wrap processor after the cotton falls into the receiver. The bale handler can include transversely adjustable cantilever supports to tension wrap for efficient cutting.

A system wherein plastic wrap on round bales of cotton is partially slit starting at one end of the bale and continuing to a location offset from the opposite end of the bale.
