Definitions

  • the invention relates to a slider needle with a slider which serves to open and close the thread space.
  • the slider needle has an elongated body, which merges into a hook at one end. At a position opposite the open side of the hook, a slide slot begins, in which the slide is arranged.
  • the slider has two slide springs which lie flat against each other and are slidable together in the slot on the hook and away from it. The two slider springs are bent away from each other at their hook-facing corners to form a funnel for receiving the hook tip.
  • the slider needle for a flat knitting machine.
  • the slider needle has a slider with two slide springs. These are rounded at their end facing the hook, wherein the measured parallel to the flat side of the needle needle height of the end of the slider spring decreases towards the end of the spring down.
  • a needle is known whose slide is also made of two slide springs. These form a funnel with each other at their free ends and are otherwise bent away from each other in a bulbous manner. The lateral bulging of the slide springs serves to center them in the slide slot, so that the funnel formed by the slide springs can be pushed well centered over the hook tip.
  • a slider needle with a slider which has a mesh support shoulder. From the mesh support shoulder, a slider portion extends in the direction of the hook. The height of the slide section decreases to its tip, so that the slide tapers to its tip.
  • the slider needle according to the invention has a slider with two slide springs.
  • the slider may be formed in one piece or from a plurality of individual pieces (slide springs, slider body), which are detachably or permanently connected to each other.
  • the ends of the slide springs are tapered.
  • the thickness of the slider springs continuously decreases in a taper region limited to the funnel portion toward the ends of the slider springs.
  • this results in a larger inner funnel width so that the safety with which the slide is pushed over the hook also increases under difficult conditions and with advanced wear.
  • the outer contour of the funnel is not widened, this is not bought by increased friction.
  • the outer width of the funnel can be reduced, at the same time obtaining a funnel with a funnel width, as was the case with conventional slide needles.
  • the slider springs may be convenient to provide only one of the slider springs with a taper and form the other in a conventional manner with a non-tapered end. This is particularly useful in cases where the slide is exposed to a previously known lateral stitch or other lateral force. In general, however, a symmetrical (mirror-image) design of the slide springs is preferred, so that the accuracy of the slider and the hook is generally increased.
  • the taper of the slider springs manifests itself in a decrease in the thickness of the slider spring, measured transversely to the direction of movement and at right angles to the side surfaces of the slider needle.
  • the thickness decrease is continuous.
  • the free ends of the slide springs are preferably rounded with a very small radius of curvature. However, sharp edges are preferably not present at the free end of the slider spring. This avoids Damage or injury to the fabric and / or thread.
  • the tapering region is preferably shorter than the funnel.
  • the taper of the slider springs is limited to the area thereof in which they are spread apart from each other.
  • the slide springs may have an approximately rectangular cross-section in their tapering region. This is achieved by a simple flattening of the mutually bent slide springs. It is alternatively possible to restrict the taper to, for example, a central part of the slider spring, so that it is then provided on its inside with a recess for receiving the hook, which recesses and widened towards the free ends of the slide springs. Also, this measure can improve the properties of the needle, as stated above, in addition, an increased stability of the slide springs is achieved.
  • FIG. 1 a slider needle 1 is illustrated, on the base body 2 at one end a hook 3 is formed. This has with its tip 5 on a slide slot 4, which is limited in the transverse direction Q of two slot walls 6, 7. In the slide slot 4, a slide 8 is guided, to which two slide springs 11, 12 belong. These are held on a slider body 14.
  • the slider is displaceable in a longitudinal direction L on the hook 3 and away from it.
  • FIG. 3 the needle body is visible in plan view.
  • the hook 3 is flattened laterally. Its side edges 16, 17 are in FIG. 3 arched inward arcuately in plan view.
  • the slider 8 is separated FIG. 4 seen. Its two slide springs 11, 12 are substantially flat against each other. Optionally, they may be bulged outwards in a region 19 remote from the slider end 18.
  • the slider end 18 is defined by two legs 21, 22 of the slide springs 11, 12, which are bent away from each other.
  • the slide springs 11, 12 terminate in ends 23, 24 which are spread apart from each other and held at a distance T from each other.
  • the legs 21, 22 begin at a contact point 25, in which the slide springs 11, 12 just just abut each other and begin to diverge to form a funnel 30.
  • FIG. 5 As can be seen, the legs 21, 22 taper starting from a thickness D in a tapering region 29 towards their ends 23, 24.
  • the rejuvenation manifests itself in one. Decrease in width, which in FIG. 5 is to measure vertically (in the transverse direction Q). It starts at the contact point 25 or at a closer to the ends 23, 24 location.
  • the rejuvenation recorded in the illustrated embodiment, the entire height of the respective slider spring 11, 12 completely. This is from the FIGS. 6 to 8 out.
  • the thickness of the slide springs 11, 12 is slightly larger (see section VII-VII, FIG. 7 ).
  • the slide springs 11, 12 have already reached their usual thickness, as the section VIII-VIII (FIG. FIG. 8 ) shows.
  • the slider needle 1 described so far operates as follows:
  • the needle body 2 and the slider 8 perform longitudinal movement in the longitudinal direction L with respect to each other so that a thread space 28 defined by the hook 3 and the slider springs 11, 12 opens and closes.
  • the thread space is closed, the ends 23, 24 of the slide springs 11, 12 spread apart from one another are pushed over the hook 3 on both sides. It is important that the ends 23, 24 not at the Toast hook tip 15. This is achieved by the ends 23, 24 defining the width W, which is large compared to the width of the hook tip 5.
  • the distance T which defines the outer width of the slider 8 at the ends 23, 24, not or not substantially wider than the slide slot 4.
  • the funnel 30 can move laterally slightly by the existing game and / or elastic deformation of the slide springs 11, 12. He is thus no longer completely centered to the needle tip 5. Due to the large width W of the opening of the funnel 30, however, the hook tip 5 can be found between the legs 21, 22, even at the most unfavorable conditions, without abutting the ends 23, 24.
  • the needle 1 is therefore resistant to wear and reliable operation even under unfavorable conditions. The reliability is not paid for by an increase in the friction of the legs 21, 22 in the slide slot 4, because the distance T is not increased despite increasing the width W compared to the conventional funnel width W1. With only a moderate enlargement of the width W, the distance T can even be reduced.
  • FIG. 9 illustrates a modified embodiment of the slider 8.
  • the legs 21, 22 of the slide springs 11, 12 are flattened only at their ends in the tapering region 29.
  • the tapering region 29 is shorter than the length of the legs 21, 22, which begin approximately at the contact point 25.
  • the flattening in the Rejuvenation region 29 may be formed as a flat surface.
  • FIG. 10 shows the leg 22, which contains a trough 31 approximately in its center.
  • FIG. 11 which shows a cross section through the leg 22 at the position XI-XI and a corresponding cross section through the symmetrically shaped leg 21, the taper is limited to the region of the trough 31, which recesses towards the end 23 or 24 (FIG. FIG. 10 ).
  • the trough 31 is arranged at a height corresponding to the height of the hook tip 5. In addition, their direction coincides with the direction of the hook 3.
  • the slide spring 11, 12, as well as the slide springs 11, 12 of the embodiments described above runs in a blunt edge 32. Their rounding prevents thread damage.
  • a slider 8 is provided with two slide springs 11, 12, the ends of which form an open to the hook 3 indicative funnel.
  • the funnel forming ends or legs 21, 22 are flattened.
  • the material thickness of the slide springs 11, 12 thus decreases, starting from an initial point, in the tapering region 29 towards the ends of the slide springs 11, 12.
  • a proper function of the needle is achieved even if the slider 8 is not completely centered.
  • the ease of movement of the slider 8 can be improved in the slide slot by narrowing the funnel formed by the legs 21, 22 at a constant width can be formed as without tapering of the slide springs 11, 12th
