ABSTRACT:
A machine for dispensing thick plastic film has two cradle rollers which carry a heavy roll of thick plastic film, two nipper rolls which draw film from the roll of plastic film, a timer regulated motor which drives the nipper rolls to dispense a pre-selected length of film and a knife to cut the film. The use of the knife reactivates the machanism to dispense a second given length of film and the process is infinitely repeated. The heavy plastic film dispensed is used to cover the sharp jagged edges of bones of primal or subprimal cuts of meat prior to the cuts being placed in plastic bags or wrapped in plastic film. The heavy plastic film protects the plastic bag or wrapping film from puncture by the jagged edges of the bones.
