Abstract
A plastic bag removal method and apparatus in which the bag is stored on a large, tightly compressed roll. In the described preferred embodiment, the method and apparatus provide for opening the mouth of the leading bag on the roll, clamping the inside and outside surfaces of each of the opposite side edges of the mouth, pulling the bag out, away from the roll, while still clamping, in order to expose the next bag in the roll, holding the mouth of the next bag in the roll while twisting the leading bag and continuing to pull on the leading bag until the sealed bottom of the bag separates from the next bag held in the roll, and placing that leading open bag onto a filling spout.
