Definitions

  • the invention relates to a device for fastening a pinstrip in a U-shaped needle carrier in needle-bearing textile machines.
  • textile machines are, for example, stretching machines, combing machines, panting machines, fibrillation machines, perforating machines, spreader bars and open-end spools and the like.
  • the needles are subject to extremely high loads, so that they often break off and the pinstripes have to be replaced by new strips.
  • the pinstripes are either soldered or glued into the groove-shaped cavities of the U-shaped needle carriers. This type of fastening is also subject to considerable stresses, for example in the form of vibrations transmitted to the material, so that the fastening is occasionally destroyed, which leads to considerable interruptions in operation.
  • the known attachment of such pinstripes also complicates the replacement of the pinstrip because the binder must be completely removed from the very narrow grooves before a new pinstrip can be used.
  • pinstripes Another type of attachment of pinstripes consists in pressing them onto the one wall of the U-shaped needle carrier by means of wedge-shaped clamping strips. This requires a considerable size, so that such attachment can not be considered in all machines. In addition, additional components such as screws and the like are in this type of fixation. necessary to give the terminal strips the required pressure and to hold them themselves. Finally, extended cavities of the needle carriers are also used at their foot end, into which the pin strip, which likewise has a widened foot, is inserted from the side. This type of attachment requires certain tolerances, which makes it difficult to reliably fix the pinstrip in the needle carrier. Above all, however, the space required for the lateral insertion of the pinstripes is rarely available in such machines.
  • the object of the invention is a simplified method of attachment of N pinstripe in a needle carrier when the needle carrying textile machines in a way that no additional auxiliary elements fixed and the static requirements of these machines causes corresponding mechanical connection at the lowest possible expenditure of time, so that a total replacement of Pinstripes can be simplified significantly.
  • the cost of replacing pinstripes should be reduced to a minimum.
  • At least one U-leg of the needle carrier is spaced apart from one another by a plurality of parallel grooves which start from the U-interior and which open out at the free leg end and which are at least at their inner end at an acute angle to the U-web extend, the pin strip laterally having cams corresponding to the distance of the grooves, which engage when the pin strip is inserted into the grooves.
  • the individual pinstrip can be easily inserted with its cams into the corresponding grooves of the needle carrier, and it receives its intended tight fit at the end of the groove.
  • the number of grooves required for the U-shaped needle carrier and cams of the pinstrip depends on the strength requirements of the individual case .
  • the cams can be attached by deep drawing during the manufacture of the pinstrip. However, it is also possible to integrally form the cams on the pinstrip if it consists of a synthetic resin molded body.
  • the grooves can have a section extending from the leg end, approximately perpendicular to the U-web of the needle carrier, and an adjoining end section running at an acute angle to the U-web.
  • Another embodiment provides that the vertical section is followed by an end section running parallel to the U-web of the needle carrier.
  • transition from the approximately perpendicular section into the acute-angled or parallel end section is arched or angled, preferably then at right angles.
  • Another modification of the invention is that at least two end sections arranged parallel to one another extend from the section of the groove which runs approximately perpendicular to the U-web.
  • the invention provides for the depth of the groove to decrease increasingly in its end section.
  • the groove thus becomes flatter towards the end.
  • the cam guided in the groove thus experiences an increasing tightening which presses the pinstripe against the opposite wall side of the U-shaped needle carrier.
  • the same effect also arises when the width of the groove decreases increasingly in its end section, so that the cam of the needle strip guided in the groove, when it is pushed forward in the groove, increasingly lifts off the groove base and thus a lateral displacement of the pinstripe.
  • the groove has a cross section approximately corresponding to the cam profile.
  • the cam cross section and / or the cam profile are preferably approximately semicircular or triangular.
  • cams can also be arranged on both sides of the pinstrip and grooves can be arranged on both U-legs of the machine element referred to as the needle carrier. These cams or grooves arranged on both sides are expediently offset from one another.
  • the invention naturally also includes the reversal of the arrangement in that the cams are arranged in machine elements, ie the needle carrier, and the cams receiving grooves in the pinstripe without this changing the basic principle of the invention.
  • the invention provides that the needle carrier has a window in the U-legs opposite the grooves for each groove. In this way, the milling process required to produce the grooves can be carried out easily even in the most confined spaces. Of course, access to the U-cavity from the opening side is also possible.
  • needle carrier 2 In the textile machine equipped with a large number of needles 1, machine elements are stored in a number corresponding to the rows of needles, here referred to as needle carrier 2, which have a U-shaped cross-section and are made from the two U-legs 3 u. 4 and the U-web 5 connecting them.
  • the cavity 6 of the needle carrier 2 serves to receive a needle strip 7, in which a certain number of needles 1 are fixed at a precisely predetermined distance from one another.
  • a pinstripe 7 can have a very different design. It is prefabricated and is inserted in its entirety into the needle carrier 2 fastened in the textile machine and in turn firmly anchored therein.
  • the needle strip 7 has cams 8 which are arranged at a distance x from one another and at the same height and which have an approximately conical shape.
  • the pinstripe 7 is formed using an angular rail 9 or a U-shaped rail 10, the cams 8 can be shaped, for example, by deep drawing in the corresponding rail 9 or 10. If, on the other hand, the pinstripe 7, as in the embodiment according to FIG. 9, has a synthetic resin or plastic body 11, the cams 8 "are integrally formed on it.
  • the U-shaped needle carrier 2 has, in a number corresponding to the number of cams 8 of the needle strip 7 and a distance x used there between the cams 8, a series of grooves 12 which are milled into the inside of the leg 4 of the needle carrier 2.
  • These grooves 12 consist of a section 14 opening at the free end 13 of the leg 4, which, with the exception of the embodiment according to FIG. 14, extends approximately perpendicular to the U-web 5.
  • This section 14 is then connected via an arch 15 (see Fig. 12) or at a right angle 16 or at an obtuse angle 17 (see FIG. 13) to an end section 18 which, in the embodiments according to FIGS. 12 runs approximately parallel to the U-web 5 of the needle carrier 2. In the embodiment according to FIG. 13, this end section extends at an acute angle to it.
  • the embodiment according to FIG. 14 reveals a solution in which the entire groove 12 ′ extends from the free end 13 of the U-leg 4 in a straight line and at an acute angle y to the U-web 5. Apart from certain tolerances, the cross section of these grooves 12 corresponds to that of the cams 8 of the pinstrip 7.
  • FIG. 8 of the pinstrip 7, each with two cams 8 located one above the other corresponds to an embodiment of the needle carrier 2 according to FIG. 13, in which the section 14 of the groove 12 is adjoined by two obliquely running end sections 18 arranged parallel one above the other, each of which pick up one of the cams 8 '.
  • FIG. 9 shows an embodiment with cams 8 ′′ arranged obliquely one above the other, which, which is not reproduced in detail, but is self-evident, requires a corresponding groove formation of the associated pin strip 7.
  • Fig. 5 shows that the arc 19 of the end portion 18 of the groove 12 decreases towards the end, i.e. the groove becomes increasingly flat.
