ring size on the rod and tubular woven around snapping and a certain tension. Thus, on the circumference of the cylinder has a resistance f cloth every place, and let the cloth around the barrel try to balance the force that produces woven around the elastic elongation equal as possible. Second, the folds of cloth roller and disposal site (1) of fold rollers roll portion (2) of the folding rollers roll analyze the reason for tubular fabric is folded into flat woven, woven and flat sides and is surrounded and enclosed parcels conditioning friction rod passes. If one side of the web, including woven and conditioning without snapping lever in the force of the pulling roll to enhance both ends, and on the other side due to friction, so that both ends and the other side of the woven edges in the elastic range is elongated, and including but not conditioning lever contact side of the web, no frictional resistance or friction intermediate portion is small, so the intermediate woven fabric is not
