Definitions

  • the invention relates to a method for the thermal cutting of a continuously moving, meltable textile web according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 6.
  • meltable textile web is cut by means of a hot cutting wire, the cutting wire being inclined transversely to the cutting direction at an angle of 90 ° to the textile web.
  • the object of the invention is to provide a method and a device for the thermal cutting of a running meltable textile web with which the disadvantages mentioned above are avoided, i.e. in particular the cutting edges of the textile web are to be improved.
  • the arrangement of the active part of the cutting wire which is inclined at an angle 90 °> ⁇ > 0 ° transversely to the direction of movement of the textile web relative to the guide plane, makes it easy oblique cut, which on the one hand assigns part of the melt mass to a waste strip and on the other hand the melt edge lies on the back of the textile web and is therefore not noticeable.
  • the edges of the cut surface are quasi rounded and have practically no scratching properties. Due to the extended cutting surface of the oblique cut instead of the vertical cut the threads of the textile web melted better together, which also improves the cut edge of the textile web. Thanks to the sloping cut surface, the cut textile web can be bent by significantly smaller radii without breaking than is possible with vertical cut surfaces.
  • the cutting process can take place along a straight line and / or any path.
  • the cut can be carried out using a single straight cutting wire, which is accordingly inclined.
  • An embodiment according to claim 2 is particularly advantageous since two material webs can then be cut with one cut at the same time, the part of the material web that lies within the V can be removed as waste waste. With this waste waste, part of the melt mass created by the cut is already removed.
  • a cut which has a wedge-shaped cross section can be produced by means of an X-shaped cutting wire.
  • An embodiment of the method according to claim 4 is particularly advantageous, in which case the greater part of the melt mass lies on the back of the textile web and is therefore not noticeable on the good side.
  • the cut is made through the homogeneous base fabric.
  • the edge is quasi rounded and has practically no scratching properties.
  • the cut is divided visually into the cut through the base fabric and the cut through the figure fabric or the figure threads lying on the back of the fabric.
  • the cut through the base fabric proves to be very homogeneous in the density and in the colors of the base fabric.
  • the front edge does not have the usual visible mixed color effects as with the known vertical straight cut. Due to the longer cutting length of the oblique cut, the figure threads in particular are also better fused to one another. Pulling out the threads is hardly possible without destroying the label.
  • the sloping cut surfaces can be optimally pressed together by rollers.
  • the material on the rear hinge side lies well against the middle of the hinge side. This results in a very fine, thin, non-scratching band edge.
  • An embodiment of the method according to claim 5 is also particularly advantageous.
  • the warp thread with the higher temperature resistance inserted in the complementary cutting method provides an optimal guiding possibility for the V-shaped or X-shaped cutting wire. The latter is thus guided along the cutting direction on such a warp thread, so that an extremely straight, thread-precise cut is produced.
  • FIG. 1 shows a cutting head which is suitable for cutting a wide variety of textile webs and for a wide variety of uses. It is particularly suitable for a device for producing a patterned label tape according to EP-A-0389793.
  • the cutting head contains a holder 2, which can be attached to any support of a textile web production system. Angled support arms 4, 6, 8 are arranged on the holder, the free ends of which point against the running direction of a textile web.
  • a cutting member 10 is attached, which consists of a cutting wire 12, which is arranged in a V-shape.
  • one end of the cutting wire 12 is fastened to a support arm 4, looped over a lower support arm 8 and further fastened to the second support arm 6 located at the top.
  • the current required to heat the cutting wire 12 is supplied via the support arms 4, 6.
  • FIG. 2 shows the cutting wire 12 in use on a meltable textile web 14.
  • the legs 16, 18 of the cutting wire 12 are each inclined at an angle ⁇ transverse to the cutting direction to the surface 20 of the textile web 14.
  • the arrangement is such that the cutting wire 12 with its crossing point 22 of the legs 16, 18 lies just below the textile web 14 and separates it by melting the textile threads.
  • the textile web 14 is provided with a warp thread 24 along the cutting line, which has a higher temperature resistance than the neighboring textile threads. This cuts the cutting wire 12 along the warp 24, i.e. guided along the cutting line.
  • molten cut surfaces 26, 28 are formed, which are arranged in a V-shape in accordance with the cutting wire 12.
  • the melting surface at the cutting surfaces 26, 28 is reduced, as a result of which the formation of burrs is suppressed.
  • the oblique position of the cut surfaces 26, 28 results in a larger melting surface, which improves the fixation of the threads of the textile web.
  • the protruding edge 32 is assigned to the good side 34 of the textile web 14, and accordingly the rear edge 36 lies on the back 38 of the textile web, the cut surface 26, 28 practically does not appear on the good side 34 of the textile web .
  • the inclination of the cut surface also prevents the formation of beads or brows on the cut surface or in particular on the good side, i.e. prevented at the viewing area. This improves the appearance of the cut textile web and results in a softer, practically non-scratchy interface.
  • FIG. 3 shows a V-shaped cutting wire according to FIGS. 1 and 2 on a textile web 40, but without one Warp thread 24 according to Figure 3, which would serve to guide along the cutting line. In the cutting process according to FIG. 3 there is practically no waste waste between the legs 16, 18.
  • FIG. 4 shows a further cutting wire 42 which is X-shaped.
  • the arrangement is such that the point of intersection 46 of the cutting wire 42 lies within the textile web 44, so that an angled cutting surface 48 is formed which has edges 50, 52 set back on both sides of the textile web.
  • any waste waste 54 that arises is removed after the cutting.
  • FIG. 5 shows a further cutting element 56 which is designed in the form of a single cutting wire 58 which is inclined at an angle ⁇ transversely to the cutting direction to the textile web 60. Since the cut surfaces 62, 64 are complementary, the two textile web sections 60a, 60b either have to be used with different upper sides or the textile web section 60a, on the good side of which the edge 66 is set back, has to be cut again with a cutting wire 56 which is opposite is inclined to the cutting wire of Figure 5.
  • the cutting wires are each made of round material. However, it is also possible to form the cutting wires from a flat material, the narrow side of which forms the cutting edge.
  • FIG. 6 shows a weaving machine with a device for thermal cutting according to one of FIGS. 1 to 5.
  • the weaving machine is used to produce patterned label tapes by thermal cutting of a broadly woven textile web.
  • the weaving machine contains a weaving area 68 with warp threads 72 of meltable material guided on strands 70, as a result of which they form a weaving shed 74 into which a weft thread 76 is inserted and struck on a selvedge 80 by means of a weaving reed 78.
  • a fabric hold-down device 82 is used to guide the woven textile web 84 to a thermal cutting device 86, on which the textile web 84 is cut into ribbons, which are pulled off by a goods take-off device 88 and fed to a goods tree (not shown in more detail).
  • the goods take-off device 88 contains a first deflection roller 90, a removal roller 92 and further deflection rollers 94, 96. It is also equipped with a heat-fixing device 98. The latter contains a shoe 102 heated by means of a heater 100.
  • the cutting device 86 has a cooler 106 arranged on a carrier 104 which overlaps the textile web 84 and each contains support arms 108, 110, which carry the cutting member 112 at their front end region which points against the running direction of the textile web.
