Definitions

  • a row of fastener elements for a slide fastener comprises a continuous spiral-shaped thread having a varying pitch, each whorl of the spiral thread having two.
  • the connecting sections between the suc- I cessive whorls, opposite the teeth each have a respective bend facing towards the teeth and the totality of said bends forms a series of notches along the corresponding longitudinal edge of the row of fastener elements.
  • the stitching consists of two parallel longitudinal rows, one of said rows being at an intermediate point in the space between the teeth and the connecting sections, preferably close to the connecting sections, and the other being along the edge of the row of fastener elements opposite to the teeth and disposed inside the notches.
  • the stitching is double chain-stitchmade with two needles, the chains being positioned over the end of the whorls opposite to the teeth.
  • the teeth of the fastener elements in each row generally consist of a deformation at the end of each whorl of the spiral, on the side facing the other row of fastener elements.
  • This deformation may with advantage consist of a flattening of the section of the thread.
  • Another solution used to ensure the firm fixing of each spiral consists of making the whorlsin a special shape, so that they cannot come loose by slipping under the stitches.
  • the whorls can then be flattened at the place where the stitching is, and be of a certain height on the side of the sentially characterized in that, on the side opposite to the teeth, the connecting sections between the successive whorls each have a bend pointing towards the teeth, these bends forming a series of notches along the corresponding longitudinal edge of this row of fastener elements.
  • notches enable the latter to be fixed by means of an extra row of stitching, the stitches of which are positioned inside the said notches and thus on the outside of the connecting sections between the different whorls. This enables the spiral to be firmly fixed because, additionally, a row of stitching is provided in the other side.
  • This invention also concerns a slide fastener unit consisting of a row of fastener elements as defined above and which is fixed on to its backing tape means of two rows of stitching so positioned.
  • FIG. 1 is a diagrammatic view from above of a fastener unit in accordance with the invention
  • FIG. 2 is a cross-sectional view of the row of fastener elements forming part of this fastener unit
  • FIG. 3 is a diagrammatic perspective view of a par ticular embodiment of this unit.
  • the row of fastener elements included in this fastener unit is made up, in the known way, of a continuous thread 1, made forvexample of synthetic resin, which is spiral-shaped.
  • the latter has a varying pitch, so that the two legs 2a and 2b of each whorl are substantially superimposed in the same plane perpendicular to that of the tape 5 on which this spiral is to be fixed.
  • the teeth of the linking components consist, in known manner, of a flattening 3 formed at the end of each whorl and designed to be turned towards the other row of fastener elements.
  • connecting sections 4 are of course at an angle in relation to the plane of the backing tape 5 on which the spiral is to be fixed.
  • each of these connecting sections 4 comprises a bend 6 projecting towards the teeth 3.
  • These different bends thus form, on the opposite side, a series of notches 7 positioned between the various successive whorls. These notches are thus positioned along the longitudinal edge of the spiral which is on the side opposite to the teeth.
  • the row of fastener elements so formed is fixed on to a backing tape 5 by stitching.
  • this fixing is effected by two separate rows of stitching, the positioning of which is shown by the dot-and-dash lines A and B.
  • the first of these, -i.e., row of stitching A, is positioned in the usual place, thus at an intermediate point in the width of the spiral, between the teeth 3 and the As regards the second row of stitching B, it is positioned in a quite unusual place, which is in fact an important innovation in the invention.
  • This row in fact goes over the ends of the whorls on the side opposite to the teeth 3. This is made possible by the presence of the notches 7 formed by the bends 6 provided in the connecting sections between the whorls.
  • the sewing needle can then be inserted inside each of these notches.
  • two needle insertion points 9 through the tape are provided inside each notch 7.
  • this second row of stitching prevents the spiral from slipping sideways in the direction of the arrow F
  • the loops formed by this row 'of stitching are in fact positioned over the end of the whorls opposite the teeth 3, while the insertion points 9 going through the tape 5 areon the outside of the spiral, inside the notches 7.
  • these can consist of a double chain-stitch 10, achieved by means of two needles.
  • This chain-stitch is obtained by providing for the insertion points of the two needles to be positioned along two parallel lines A and B, so that the positioning is the same as the insertion points 8 and 9 shown in the diagrammatic view in FIG. 1.
  • fastener unit in accordance with the invention is not limited to the constructional examples which have been described above by way of example.
  • the stitches used to fix the spiral could be of a different kind, providing their position remainsthe same. It would thus be possible to use a zigzag stitch.
  • This fastener unit is of course designed to be associated with an identical unit to form a slide fastener fitted with a slide and the usual stops at the two ends.
  • the fastener so obtained has the advantage of being very strong, since the two rows of fastener elements cannot under any circumstances come loose by slipping sideways under the stitches of the fixing seam.
  • ThIS fastener also has the advantage of being very neat since the whorls formed by the two rows of fastener elements can be completely flattened over the whole of their width.
  • a row of slide fastener elements to be secured to a backing tape of soft material comprising a continuous spiral-shaped thread having a varying pitch, each convolution of the spiral threadhaving two legs which are substantially super-imposed, and each convolution being separated from each other convolution, each convolution having at a'first end portion thereof a deformation to serve as a tooth of a fastener element, connecting sections between the successive convolutions opposite the teeth each have a respective bend facing towards the teeth, the totality of said bends forming a series of notches along the corresponding longitudinal edge of the row of fastener elements, means to secure said row of slide fastener elements, by stitching, onto said backing tape, said stitching comprising two parallel longitudinal rows of stitches, a first said row of stitches being located close to said connect, ing sections of said convolutions and being disposed at an intermediate point in the space between the teeth and the connecting sections, and a second said row of stitches being disposed along the edge of the row of fastener elements opposite the teeth, the stitches of said second row
