Abstract
A method for separating a pair of plastic bags, connected together at a transversely disposed parting line, comprises the steps of intermittently moving the pair of bags along a path disposed in a horizontal plane, stopping the bags and placing the parting line over an opening extending transversely relative to the path and positioned between a pair of platens, clamping the pair of bags to the platens and severing the parting line to separate the pair of bags from each other by moving a cutting blade in a horizontal direction and transversely through the opening.
