Definitions

  • the invention relates to a pinstrip holder for textile machines, in particular for combing machines, open-end spinning machines and intersecting machines with a pinstrip comprising a plurality of needles fixed to a plastic strip, the pinstrip being positively attachable to the needle holder.
  • the object of the invention is to make pin strips with a plastic strip in a pin strip carrier, in particular made of metal, easily and securely fixable and detachable.
  • plastic strip is fixed to recesses in the pinstrip support in that the plastic of the plastic strip is thermally or chemically dissolved or melted to form a projection which projects into or out of the recess.
  • the invention is therefore based on the idea of combining a purely mechanical, form-fitting fastening with a fastening by chemical or thermal deformation of the plastic strip, with a very slight deformation of the plastic strip being sufficient to achieve an unusually tight fit of the pin strip due to the form-fitting basic connection , such a slight deformation is in turn easily canceled.
  • the plastic strip has lateral projections which laterally positively penetrate corresponding recesses in the pinstripe support, their free ends emerging on the outside of the recesses being thermally or chemically deformed to form a retaining head which overlaps the edges of the recess.
  • the pin strips are already in the radial direction due to the positive connection, i.e. in the direction of the centrifugal force acting on the pinstrip during operation.
  • the thermal or chemical deformation of the side lugs also ensures that, even in the tangential direction, an absolutely secure fit is ensured against forces which act on the pinstrip in the opposite direction to the combing direction.
  • the free ends of the lugs be deformed by painting over with a heating element or a heating gun.
  • a pinstripe defined in this way can easily be removed by machining the holding heads, e.g. by drilling out.
  • the pinstripe support is essentially J-shaped in cross-section, that a holding groove for the pinstrip is formed on the inside of the J-profile, that in the foot region of the holding groove at least in sections Undercuts are provided and that corresponding holding projections are arranged in the foot region of the plastic strip of the pinstrip, at least in sections.
  • This embodiment is particularly suitable, for example, for chain drafting systems.
  • the pinstripe support is U-shaped in cross section, that the plastic strip of the pinstrip is inserted into the inside of the U-profile serving as a holding groove, that the side walls of the Plastic strips are essentially smooth, and that the side walls of the plastic strip are melted or dissolved chemically or thermally through recesses in the U-profile.
  • plastic pins are melted onto the plastic strips of the pin strips from the outside through the recesses of the pin strip holder to fix the pin strips.
  • a solvent dissolving the plastic of the plastic strip is applied through the recesses.
  • a solvent dissolving the plastic of the plastic strip is applied through the recesses.
  • the loosening of the pinstripes can be done by mechanical cutting, e.g. by boring.
  • 1 to 5 show an embodiment of the type which is suitable, for example, for chain drafting systems.
  • FIG. 1 and 2 show a pinstrip 1 which comprises a plastic strip 2 and a plurality of needles 3 which are inserted into a groove 4 of the plastic strip 2 which is U-shaped in cross section.
  • the needles 3 can be fixed by overmolding with the plastic strip 2 or in a mechanical manner.
  • lugs 6 On one side wall 5 of the plastic strip 2, a plurality of lugs 6 are formed, which are cone-shaped.
  • lugs 6 On the foot 7 of the pinstrip 1, a web-like, longitudinal holding projection 7 'is formed on the side facing away from the lugs 6.
  • a pinstripe support 8 which has a J-shaped cross section in the embodiment.
  • a holding groove 9 is formed on the inside of the J, an undercut 10 running in the region of the bottom of the holding groove 9, which corresponds in cross section approximately to the holding projection 7 '.
  • a plurality of recesses 12 extend through the upwardly extending section 11 of the pinstripe support 8 and correspond in diameter and position to the projections 6. Accordingly, the plastic strip 2 of the pinstrip 1 can be inserted obliquely in the direction of arrow 13 in FIG.
  • FIGS. 6 to 12 The embodiment shown in FIGS. 6 to 12 is suitable, for example, for drafting systems with a cam drive.
  • FIG. 6 shows a pinstrip 1 ', the base part of which is designed as a plastic strip 2', the needles 3 'being mechanically fixed to the plastic strip 2'.
  • a pinstrip support 8 'shown in FIGS. 8 to 10 is U-shaped in cross-section, with a holding groove 9' for receiving in the interior of the U-profile the plastic strip 2 'is used.
  • the plastic strip 2 'of a pinstrip 1' is pressed into this groove 9 'in a form-fitting manner, as is shown in FIG. 8.
  • the side walls 11 'of the pinstripe support 8' have recesses 12 '.
  • pin-shaped plastic parts 6 ' are melted by means of a commercially available heating gun, not shown in the drawing, and inserted in the melted state through the recesses 12', so that the plastic of the plastic strip 2 'of the pinstrip 1 'is melted and the plastic parts 6' enter into a connection with it.
  • the plastic parts 6 ' will preferably be selected from a plastic which corresponds to the plastic of the plastic strip 2' or is at least chemically similar to it so that the two plastics can fuse.
  • the side wall 11 'of the pinstrip support 8' has one or more elongated holes 12 '' instead of a plurality of round recesses 12 '.
  • the attachment can take place in this embodiment in such a way that the plastic strip 2 'is melted directly through the elongated hole 12''with a type of soldering iron or a type of soldering gun, so that it partially engages in the recess 12''so that it is solvent-treated is chemically dissolved or that, as described in connection with FIGS. 8 to 10, melted Plastic parts are used as a kind of retaining bolt.
  • FIG. 12 shows how simply a pinstrip 1 'can be fixed chemically in a pinstrip holder 8' by applying a solvent 18 in the form of drops 19 into the side recesses 12 'by means of a metering device 17, which Plastic of the plastic strip 2 'loosens. If, for example, polystyrene is used as the plastic for the plastic strip 2 ', a solvent based on benzene or toluene is suitable. With such a material combination, very high holding forces were achieved in tests. Nonetheless, drilling, milling or grinding makes it easy to loosen the connection thus produced.
