The web of the packaging material on the first grooved roller are transported in the direction generally parallel to the grooves by powering the first grooved roller. The web of the packaging material spanning the nonprojecting portions of the first grooved roller is impinged by the tips of the projecting portions of an idling second grooved roller to stretch the sheet between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the sheet is transported. The web is preferably separated from second grooved surface either before or simultaneous with its separation from the first grooved roller.
