摘要： In U-shaped closing staples 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. An apparatus for closing bags and flexible tubes by means of such closing staples comprises a closing punch (9), which acts on a die (8) and is formed in its active surface (29) with a groove (10), which has the same width as the closing staple and has a depth which is smaller than the total thickness in which the legs are subjected to the closing operation. During the closing operation the side wall faces of the groove (10) guide the leg ends (6) and ensure that the staple leg ends (6) firmly engaging the staple legs (4) on the outside will be embossed without a formation of a burr.

摘要： In a plastic clip which serves to close sausage casings, bags or the like and consists of two interlockable parts (1, 10), at least one part (1) consists of an elongate frame, which has side bars (2), which have a large height in relation to their wall thickness. The side bars (2) are provided with central recesses (4), into which the end of the wrapper, which end has been gathered to form a tip, can be inserted. The other part (1; 10) together with the first part encloses the wrapper and that has been gathered to form a tip. At least the other part (1; 10) is provided with a projection, which consists of a rib (13), which extends parallel to the side bars and protrudes into the interior (5) of the frame. That projection deflects the tip in wave shape and applies pressure to the tip at the same time. For this reason, the clip will have a maximum elastic yieldability and, as a result, a maximum adaptability to different tip thicknesses or different pressures in the closed interior space in conjunction with a strong and uniform seal whereas the firm detent connection is not adversely connected. In a first embodiment the two clip parts are identical. In a second embodiment the first part encloses the tip by a U-shaped recesses, which are formed in the side walls and closed by the second part.
