Definitions

  • the invention relates to a needle holder with pin strips for textile machines, for example for needle bar sections, gill spinning machines, combing machines or the like.
  • needle holders with pin strips a large number of needles are arranged in series and the needles are each fixed with their blunt ends in a plastic strip.
  • the plastic strip in turn is fastened in the groove of a needle holder, usually glued or melted.
  • the plastic strip usually consists of a more or less flexible thermoplastic, which has the advantage that it can be easily fitted into the groove of the needle holder.
  • a device for fastening a pinstrip in a U-shaped needle carrier in needle-bearing textile machines is known.
  • This device is based on the idea of arranging, in at least one U-leg of the needle carrier at a distance from one another, a plurality of parallel grooves starting from the U-interior and opening at the free leg end, at least at their inner end at an acute angle to the U-web run.
  • the pinstripes in turn have correspondingly arranged side cams which engage in the grooves when the pinstrip is inserted and lock the pinstrip in the manner of a bayonet catch.
  • the invention has for its object to simplify the attachment of the pinstrip in the needle holder even further.
  • a needle holder with a pinstrip of the conventional type which, however, is characterized in that the pinstrip is fastened in the groove of the needle holder by a mere interference fit.
  • the dimensions of both the needle strip and the groove of the needle holder are matched to one another, so that when the needle strip is pressed into the groove of the needle holder, a sufficiently firm clamping is achieved.
  • protrusions are formed on at least one side surface of the pinstrip, between which there are spaces of such a size that they can accommodate the material displaced when the pinstrip is pressed into the groove of the needle holder.
  • the elevations may take the form of stripes, ribs, bucca or the like. exhibit.
  • the volume of the elevations is preferably designed so that an adequate press connection is achieved, taking into account the tolerances of the groove of the needle holder. It is proposed to be particularly advantageous that the inner surfaces of the grooves of the needle holder are roughened, so that the flowing material that deforms when the needle strip is pressed in can claw in the roughening.
  • Pressing the pinstrip into the groove of the needle holder is very simple using the proposed measures.
  • the needle holder is inserted with the groove facing upwards in a fastening device under an appropriately dimensioned press.
  • the press contains the pin strip provided in a holding tool in such a way that the plastic strip of this pin strip arrives in the groove of the needle holder when the press is lowered.
  • the press then presses on the end face of the needle strip facing the needles and pushes the plastic strip into the groove with deformation.
  • the process is completed in a few seconds; additional heating is not required, and there is no need to manipulate with adhesive or wait until the adhesive has hardened.
  • needle holder designated 1. It consists of a narrow, elongated central part 2, into which a groove 3 open to one side is incorporated.
  • the two end jaws 4 and 5, which serve to transport the needle holder in the textile machine, are molded onto the central part 2 of the needle holder.
  • the pinstrip 6 is used in the groove 3 for use.
  • This pinstripe consists of a plurality of needles 7, which are arranged in a row and fastened with their blunt ends in a plastic strip 8.
  • Fig. 1 only some of the needles arranged in series are shown; in fact, almost the entire length of the plastic strip 8 is filled with needles.
  • the pinstrip 6 is fastened in the groove 3 of the needle holder 1 by a mere interference fit.
  • elevations 11 are formed on at least one side surface 9; 10 of the pinstrip, between which there are gaps 12 of such size that they can accommodate the material displaced when the pinstrip is pressed into the groove of the needle holder.
  • the elevations can have the form of ribs 13, humps 14 (FIG. 6) or also elongate formations 15 which, according to FIGS. 4 or 5, are arranged in different directions on one or both side surfaces.
  • the plastic strip 8 is preferably equipped with a cover strip 16, which serves to make it easier to grip the pressing tool and which serves as a stop for the needle strip and ensures that all the needles comply with the prescribed requirements have free needle length.
