Definitions

  • the invention relates to a device for fastening a pinstrip in a cross-sectionally U-shaped needle carrier in the case of needle-bearing textile machines, wherein several cams are arranged next to one another at a distance on the inside of at least one U-leg of the needle carrier and the pinstrip is arranged laterally at a distance between the cams Corresponding distance parallel grooves are assigned for the engagement of the cams, which open out at the foot of the needle strip and which run at least at their inner end at an acute angle or parallel to the U-web of the needle carrier.
  • the task of such a device is a simplified way of fastening pinstripes in a U-shaped needle carrier in needle-bearing textile machines, such as stretching machines, combing machines, pike machines, fibrillation machines, Perforating machines, spreaders and so-called open-end spools and the like.
  • the type of attachment is intended to bring about a fixed mechanical connection between the pinstrip and the needle carrier, which corresponds to the static requirements of this machine, without additional complex auxiliary elements, so that in particular the replacement of pinstrips is simplified by reducing the time required for this and the cost is reduced to the lowest possible extent can.
  • the invention according to the earlier patent application solves this by the engagement of cams attached to one element in corresponding grooves on the other element, a tight fit possibly being achieved in the final stage of the engagement of the two elements with one another.
  • the cams are generally provided on the pinstrip, the grooves, on the other hand, are provided on the machine-side needle carrier, although the reversal of this arrangement has also been included in the scope of the invention.
  • the present application which is characterized according to the invention in a further embodiment of the subject of the earlier patent application, is characterized in that the grooves on the side face of a pin strip at least on one side and on the end face bearing the needles, with the pin strip in insert the needle carrier . cash holding strip are arranged.
  • the further development according to the invention requires an additional component in the form of a hat strip, but this measure considerably simplifies the process, since the pin strips themselves need not have any additional configuration with cams or corresponding grooves.
  • the retaining strip is in turn anchored in the U interior of the needle carrier, and it overlaps the outer end face of the pinstrip with an angle leg, which undergoes no changes compared to those for conventional machines. It is sufficient if the retaining strip only partially overlaps the end face of the pinstrip, but to such an extent that the pinstrip is held reliably. This becomes particularly important when the needles of the pinstrip are very close apart.
  • the invention provides in a further embodiment that the retaining bar is U-shaped in cross section and rests on one side and the two opposite end faces of the pinstrip.
  • This retaining strip takes up the pinstrip in the recess that is open on one side so that its needle shafts with the needle tips protrude on the end.
  • the leg of the holding strip which bears against the end face of the needle strip bearing the needles preferably has recesses for the passage of the needle shafts. According to another alternative, these can be open towards the end of the retaining strip leg.
  • a further embodiment of the invention provides that holding pins are arranged on the leg of the holding strip which lies against the end face of the pinstrip which can be locked in openings in the U-web of the needle carrier.
  • Such attachment complements that by the engagement of the cams of one element in the grooves of the other element in contact with it and thus represents a further safeguard without, however, making it difficult to loosen the pinstrip.
  • openings can have an extension for the passage of an enlarged head of the holding pins and a slot which laterally adjoins in the opposite direction to the course of the inner end of the grooves in the holding strip, for receiving the shaft of the holding pins.
  • a wedge-shaped tightening between retaining pins and openings or slots in the U-web can also be brought about here by appropriate shaping when the pin strips are moved laterally.
  • cams consist of pins inserted into the bores of a U-leg of the needle carrier and their tips protrude into the interior of the U. This measure considerably simplifies the manufacture of the device.
  • the pinstripe 1 which is shown essentially schematically, carries a plurality of needles 2 next to one another at a more or less large, but regular, distance.
  • the needle shafts not shown in detail are in the body 3 of the pinstrip 1, for example by soldering, gluing or the like. fixed. If the needles 2 are worn out appropriately, the pin strips 1 are replaced, with the lowest possible downtimes of the machine.
  • the needle carriers 4 which here have a U-shaped cross section and from the U legs 5 u. 6 and the U-web 7 exist.
  • the interior 8 of this needle carrier 4 is used to fasten one pinstrip 1 each.
  • the device uses an additional holding strip 9, which is angular in the embodiment shown in FIG. 1.
  • the L-leg 10 is intended to rest on the side surface 11 of the pinstrip 1.
  • the angled short leg 12 engages over the end face 13 of the pinstrip 1, which carries the needles 2.
  • recesses 14 which are open on one side are provided on the leg 12, each of which receives a needle.
  • these recesses 14 can also be arranged in the form of closed bores in the leg 12.
  • the retaining strip 9 is pushed onto the tips of the needles 2 from above during assembly. In the embodiment shown in FIG. 1, however, the retaining bar 9 can be pushed laterally onto the pinstrip 1.
  • grooves 16 are provided at the same distance and parallel to one another and consist of a section 17 running approximately perpendicular to the U-web 7 of the needle carrier 4 and an end section 18 running approximately parallel to this U-web 7 consist.
  • the transition between the sections 17 and 18 of the groove 16 can be arched or angled, expediently at an obtuse angle.
  • bores 19 are provided at a distance from one another corresponding to the spacing of the grooves 6, and a pin 20 is captively inserted into each, the tip 21 of which projects into the U interior 8 of the needle carrier 4.
  • the retaining strip 9 is provided with a further leg 22 which bears against the foot 23 of the needle bar 1, so that this from the recess between the legs 10 u. 12 and 22 is included.
  • the leg 22 of the holding strip 9 has holding pins 24 on its underside, which have a head 26 widened relative to the shaft 25. These holding pins 24 correspond to openings 27 arranged in the U-web 7 of the needle carrier 4, which have an extension 28 for the passage of the head 26 and a subsequent slot 29 for receiving the shaft 25.
  • the head 26 of the holding pins 24 engages through the widening 28 of the opening 27 as long as the corresponding cams 21 still run in the groove section 17.
  • the cams 21 are laterally displaced in the end section 18 of FIG Grooves 16 of the holding strips 9 then slide the shaft 25 of the holding pins 24 into the slot 29, which causes the holding strip 9 ′′ to be further anchored with the respective pinstrip 1 relative to the needle carrier 4.
