Requirements then the coupling elements are functional. In the figures, a zipper strip or can be securely set. Because now a section of it can be kept short, with the legs of the coupling elements engaging in openings 1 in proportion to a conductor support band 2, so that a larger row of 20 links, e.g. helical spring, is shown, the bending stability of which and thus higher security against breaking coupling elements 3 are included Transverse tensile stress also result.

This prevents the legs 6 of the coupling elements 3 from being displaced between the speed of the coupling elements or rows of links in the conductor support strip 2 and the coupling surfaces 5 of the copper conductor support strips themselves, and there remain 30 pelglieder formations or fusions. in the case of bending loads, the coupling elements are firmly engaged. In fact, the over-measured height of the coupling elements 3 must be greater than seeing that the claimed measures suffice the width of the through-holes measured in the same direction in order to break the bending stability and security against breaking 1. This increases the number of links with the waiver otherwise required for 35 ladder support tape 2 connected. The legs 6 of the connecting and filling means held derlich.

Claims (1)

1 2 Patent claim * knows, in which the conductor support tape as a woven ^p 'carrying tape is executed, its perforations Zipper strips are formed with openings in areas free of warp threads. As a result of a ladder support belt engaging, continuously, the coupling elements of the rows of links reach through those of the row of links, e.g. B. helical spring, whose 5 warp thread-free areas or openings between coupling elements see the remaining weft threads in the event of transverse tensile stress. These wefts with rear connecting parts on between threads, however, do not lie against the rear webs remaining with the perforations - connecting parts of the coupling links or link supports, with the between the perforation rows, but against the link rows and the supporting tape inner edge formed supporting fillers. In this respect, the Glicderbandstrips are folded outwards and thus only line up by the width of the filler cores covered by the row of links on their rear side through the passage, furthermore the legs of the coupling elements see interruptions or warp-free areas between the conductor support band and the coupling surface tucked through the weft threads. The roofs of the coupling elements projections or projections formed by carrier tape strips have fusions to the outside, and they are folded over the projections so that the rows of links are covered on their back side measured by their formations or fused areas. In order to fasten the rows of links at the height of the coupling elements greater than those in the same such ladder support tapes, sewing seams measured in the direction of the width of the openings are provided, which are the support tape strips and thereby run through the row of links with the conductor and filler cores. Therefore, in the course of the supporting tape. is connected, according to the main patent manufacturing relatively complicated sewing operation 1610390, characterized, NEN required. - Another known Ausfühdaß the legs (6) of the coupling links in such a manner approximately requires no sewing connection, since are chosen that the coupling surfaces (5) but for specially designed rows of links, and coupled rows of links as support tape threads 35 as toothed strips, in which the Teeth alternating (8) designed webs in the area of the rearwardly from further and narrower, serpentine connecting parts (7a) or these connecting arcs are formed. The departure. touch the fertilizer parts (7 a) yourself. security of zippers from such zippers the closure strip is so small that such - Hardly any conclusions, at least in the clothing industry let use. In addition, zipper strips are known The invention relates to a zip fastener strip in which the rows of links are sewn to conventional ■ with one in perforations of a conductor carrier tape and by a continuous row of links up to engaging, z. B. screw handle line of the coupling surfaces of their coupling elements verbenfeder, the coupling elements are covered when Querzugbean- running, open carrier tape folds, the stress with rear connecting parts on vertices are facing the coupling surfaces. In order to prevent the sewing seams from slipping on the coupling elements between the openings, avoiding the opening between the openings, these have 40 notches formed in the area of their leg openings and the inner edge of the carrying tape to accommodate the sewing seams. In this respect ■ the tape strips folded outwards and thus the row of links can also be covered on their rear side in these known zip fasteners. strip on sewing seams and thus sewing operations. The main patent teaches that the legs of the dome for attaching the rows of links to the support band members between the conductor support band and the couplers are not dispensed with. In addition, surface areas of the coupling elements must be formed or the coupling elements must have several, namely corresponding fusions, as well as the notches or fusions required over the required number of sewing seams, so that such zipper strips must also have coupling elements larger than the same Direction is not satisfactory in terms of manufacturing technology,

The invention solves this problem according to a In principle, it is known to provide continuous link zipper strips according to the main patent to connect with conductor support straps in such a way that the legs of the coupling elements that in each case the row of links are chosen long by openings, that the coupling surfaces with gekupdes relevant conductor support tape pushed through pelten link cleanliness which is used as support tape threads. In doing so, the tape strips are either placed in the area of the rear connectors inside in the direction of the inner edge of the belt 60 manure parts or these connecting parts themselves touch or vice versa outwards, i.e. backwards. At ren. However, these known zipper strips are. The advantages achieved by the invention are always cumbersome and time-consuming measures are essentially to be seen in the fact that, according to the teaching of the Required to the rows of links on the ladder support invention extremely high security against breaking to secure tapes, so that the tension and 65 coupled rows of links occurring according to the invention Transverse stresses with unchangeable position of the zipper strip is achieved, although the Rows of links in the ladder support straps recorded - rows of links on the one hand without additional acceptance can be.
