Abstract
A piston-cylinder unit causes a web of closure tape material to be withdrawn from a supply reel in steps equal to the width of each closure tape required for closing the folded-over flattened mouth end of a large sack. Each tape is severed from the leading web end by a knife and engaged by a suction bar which is swung together with two welding bars onto an inclined support for the folded-over mouth end.
