Definitions

  • a wide web is first woven on a weaving machine, in which several label tapes are produced in adjacent web zones connected at the edges. Then the wide web between the individual web zones is cut into individual bands by cutters.
  • cutters e.g. B. a stationary arranged in the wide web heated wire which produces a fusion cut and at the same time the cut thread ends melts together so that the cut edges cannot fray.
  • melting edges on the bands These melting edges are relatively hard and have a rough profile if they are not post-treated. If such untreated labels are attached to items of clothing, the rough edges of the tape are uncomfortable when wearing such items of clothing.
  • the edge areas of the two bands are still in a plastic state at the effective pressure zone of the spring.
  • the heat of the heated cutting element can affect the spring arranged closely next to it, namely through thermal radiation or through convection currents. This applies in particular if the spring is designed as a leaf spring with an opening, because the leaf spring serves as a collector for the heat which emanates from the heated cutting element passing through its opening.
  • the device according to the invention can be integrated into a weaving machine on which the broad web is woven.
  • the weft thread density of the resulting wide web fabric is determined by a draw-off roller, which not only provides for the weaving feed during the production of the wide web, but also generates the necessary high weaving tension of the warp threads.
  • a warp thread is under a relatively high thread tension of 25 to 40 g per warp thread.
  • the cutting link is always arranged in front of the draw-off roller.
  • the invention has recognized that significantly better results are achieved at the band edges if the cutting, pressure and Stutzgheder, according to claim 17, behind the take-off roller of the loom arranges, so in that fabric section that is no longer below that for weaving required high thread tension.
  • the bad results according to the state of the art are evidently because the subsequently treated melting edges develop cracks during their hardening due to the high weaving tension, which again produce roughness at the strip edges.
  • This finding of the invention has independent inventive significance, even without the measures of claim 1 or 2. Further measures and advantages of the invention result from the subclaims, the following description and the drawings.
  • the invention is shown in several exemplary embodiments. Show it:
  • FIG. 1 shows a schematic representation of a cross section through a weaving machine, where the special position of the device according to the invention is illustrated
  • the broad web fabric is in frictional engagement with the circumference of the draw-off roller 17, which thereby absorbs the high yarn tension.
  • the deflection rollers 18 arranged behind the take-off roller 17 transport the fabric section 40 there with a significantly lower tension of a maximum of 20 g per warp thread to a fabric beam 19 .

  • two electrical connections 31, 32 protrude, which here consist of angular metal sheets, one of which 21 is located above and the other 32 below the broad web 10.
  • the lower plate 32 carries the support member 33, which has a wedge-shaped cross-sectional profile.
  • the wedge tip 34 of the support member 33 is directed downwardly to facilitate assembly of the block 35 to the wide web 10, which is done from the top of the web.
  • the trowel surface 36 opposite the wedge tip 34 is flat, is in surface contact with the underside of the broad web 10 and serves as an abutment for the leaf spring 22 which is supported on it under spring pressure lower end of the wire 21.
  • the upper plate 31 is provided with a thickened head 38 at the end, which also has a fastening means 39 for the other end of the wire 21.
  • An electrical cable 43 is brought out at the upper end of the block 35, which has electrical supply lines for the heating current of the wire 21, which, which cannot be seen in any more detail, are in electrical connection with the aforementioned angular metal sheets 31, 32.
  • the electrical cable 43 can also contain electrical control lines.
  • the electric Lines of the cable 43 are contacted with electrical components 44 which are arranged inside the block 35 and are used to control the heating of the wire 21 .

  • the block 35 is braced like a sandwich between the two side plates 51, 52 by fastening screws, which protrude through bores 55 in the block 35 and are anchored in the side plates 51, 52 at both ends.
  • the structural unit 30 is fastened by means of the housing 50 to the support 41 already mentioned, which here consists of a support rail 41 running transversely across the fabric.
  • the mounting rail 41 has an upper and a lower profile strip 48, 49.

  • the housing 50 can then be tilted away from the mounting rail 41 in the direction of the pivoting arrow 65 in order to be able to dismantle it from the mounting rail 41 .
  • the pivot point for this pivoting movement 65 is then in the region of the plate cutouts 58 described on the lower profile strip 48. After pivoting away 65, the housing 50 can also be pulled off the lower profile strip 48 and thus easily removed from the support rail 41.

Abstract

L'invention concerne un dispositif de fabrication de bandes (10') textiles de préférence à motifs, réalisées à partir d'une large bande (10) comprenant un matériau fusible. Ledit dispositif comprend un élément de coupe (21) chauffé pouvant être constitué d'un fil chauffé électriquement. Afin de développer un dispositif économique et compact, l'invention propose d'associer un ressort, de préférence, un ressort à lames au fil chauffé pour former un élément de pression. Le ressort à lames (22) possède un passage traversé par le fil chauffé (21). Le ressort à lames (22) n'est pas directement chauffé mais sa zone de pression passe si près du fil (21) qu'elle agit également sur les bordures des bandes rendues plastiques lors de l'opération de découpe.
