U-shaped closing staple for bags and flexible tubes

摘要

In U-shaped closing stables for bags and flexible tubes, which staples are made of strip material and consist of a crosspiece (7) and two legs (4) and in which the leg ends of the staple have been bent off outwardly to constitute a connecting web (2), by which the staple is severably included in a train (1), the severing of each staple from the train (1) will result at the severing location in the formation of burrs, which protrude beyond the strip width of the staple and may result in damage to the closed wrapper and to other wrappers. In order to avoid that, the width of the strip adjacent to the leg ends (6) over a portion (3) of the legs (4) and over the connecting web (2) is reduced approximately parallel on both sides so that the leg ends (6) which have been bent off outwardly uniformly engage the legs (4) on the outside within the width of the strip and there is no burr protruding beyond the width of the strip. An apparatus for closing such staples is also provided.
