Definitions

  • the invention relates to a slider needle, in particular for stitch-forming textile machines.
  • a needle is known. This has an elongated body, the on one end into a hook. At one of the open Two sides of the hook start opposite each other spaced parallel slot walls and extend along the shaft. Between Slot walls is formed a slide slot.
  • Slide slot is a longitudinally movable slider arranged, consisting of two flat against each other Slide springs exists. These are in side view approximately rectangular. With an upper corner area, the slider can touch the hook or at least the point of the hook, if the slider is moved on the hook.
  • the two Slide springs are in their corresponding upper Corner slightly bent away from each other, so to to form a funnel for receiving the hook tip. This funnel opens in a direction oblique to the direction of movement of the slider.
  • the slider needs a force to move it which overcomes the slider friction in the slider slot.
  • the slider friction is for example of the Funnel size dependent. Are the slider springs at theirs free ends spread far apart from each other, so that one large funnel is formed, which is also lateral Thread pull safely hits the hook, resulting in a increased slider friction.
  • the slider needle according to the invention has at least one two slide springs having slide on which runs in a slider slot.
  • the slider can in one piece or from several individual pieces (slider spring, Slider body) formed with each other are detachably or permanently connected.
  • the slide slot is at its hooked end in a first Management area narrower than in the rest of the area.
  • the wide or (synonymously) width of the slider slot is in the second Leadership area larger than in the first guidance area, when measured at the same height above the needle back becomes. If both measuring points M1, M2 by a imaginary line G connected with each other, this is Straight G parallel to the needle back (Fig. 4).
  • the first Leadership area is narrower than its entire height the second, in needle longitudinal direction to the first Leadership area subsequent leadership area.
  • the slide springs are each belly-like curved outside.
  • the slider slot is in its width formed stepped in the longitudinal direction. At his entrance (a longitudinally forward position) he is tight, and from the entrance (one in the longitudinal direction behind He is in a second leadership area far, i. near his hook directly It is narrower at the opposite entrance than otherwise. Both management areas may partially overlap. It is also conceivable that the slide slot or at least the second guide area partially or a stepped or one of its length over its entire length U-shape deviating embodiment occupies.
  • the lateral bulging of the slide springs is preferably set so that they are in the narrowed Slider area is located when the free ends of the Slide springs, which form a funnel, over the tip of the hook pushed.
  • the length of the narrowed area and the position of the bulged areas of the Slide springs are set so that when the slide pushed on the hook, the bulging Areas of the slider springs in the narrowed slot area enter before the funnel the tip of the hook reached. This will close the funnel just before it reaches the Hook tip arrives, precisely centered, so he is very can be kept tight and despite lateral thread train hits the hook in the middle.
  • the slider friction generally low, because as soon as the slider withdrawn from the hook, the laterally advised bulging slide spring areas in the extended Slit by using low spring tension against the slot walls or even with play.
  • the slider needle according to the invention is thus less susceptible to contamination.
  • a particularly narrow design of the funnel has the effect that the Funnel forming free ends of the slide springs from each other spread away as soon as the bulbous area of the Slide springs enters the narrowed slot area.
  • the bulbous areas of the slide springs moved towards each other (compressed), bringing the free ends of the slider springs to a width from each other spread that exceeds the slot width. This can be a particularly safe work of Slider needle to be ensured.
  • the bending of the slider springs is preferably so measured that the funnel outer width is about as large like the slit width of the slider slot when the bulbous areas of the slider springs in the extended Area of the slide slot stand. This ensures one low slide friction, because the slide springs can relax in the slide slot.
  • the bulbous Areas are preferably without bias in the widened slot.
  • the slider needle has a device which when slide retraction the immersion of the same in the Slider slot causes.
  • the slide slot as it is known per se (for example from WO 01/31101) his entrance a ground-guiding surface to guide the Slide parts on. This forms an outsole for the Slider clips. Following this outsole is a Lowered floor area provided a smaller distance to the needle back, as the bottom guide surface. With the same diaphragm wall height results thereby a depression of the slide slot.
  • the rest Slot serves as a guide space in which the slide can withdraw and with little friction or with play running.
  • the slider receives the precise guidance in each case only when he with his funnel-forming slide springs emerges from the slide slot, i. if his bulging areas in the first wegfedernden Guide area to the entrance.
  • a slotted guide be provided in the corresponding curved areas the slider springs engage when the slider is retracted becomes.
  • the slide guide becomes, for example provided by two on the needle body obliquely to the Needle back arranged guide surfaces formed, which aligned at the same angle guide surfaces of Slider spring are assigned.
  • FIG. 1 shows a slider needle 1, the one needle body 2 with an end formed Hook 3 has.
  • the hook 3 opposite begins a slide slot 4, which consists of two parallel, For example, from Figure 5 apparent slot walls 6, 7 is limited.
  • a slider 8 is arranged, which, as FIG. 2 illustrates, on the hook 3 and, as Figure 1 illustrates, can be moved away from the hook 3.
  • the slider 8 has two slide springs 11, 12, which separately illustrated in FIG. 6 and on a slider body 14 are caught.
  • the formation of the slide slot 4 is in particular from Figures 3 to 5. Then run the slide slot 4 limiting slot walls 6, 7th at a location 15 close to the hook 3 flat out.
  • the position 15 represents the beginning of the slide slot 4 at the point 15 begins one in Figure 3 dashed lines, essentially plane, Bottom guide surface 16, which forms the slot bottom.
  • the slide slot 4 has a width Wl ( Figure 5).
  • the two facing each other inner surfaces 17, 18 of the slot walls 6, 7 have the distance here Wl from each other and thus form side guide surfaces.
  • the of the ground guide surface 16 and the inner surfaces 17, 18 limited area 4a of the slide slot 4 forms thus a first management area.
  • the rest of the area 4b of the slide slot 4 forms a second Guidance or running area or clearance area in which the slider 8 with less guidance, but reduced Friction can run.
  • the running area 4b is on widened whole height.
  • the slot walls 6, 7 point here inner surfaces 21, 22, whose distance W2 is greater as the distance W1.
  • in the running area 4b lowered the slot floor.
  • the Slide slot 4 at the entrance at full height narrow (W1) and otherwise at full height (W2).
  • the current in the slide slot 4 slide springs 11, 12 are shown separately in FIG. she have free ends 26, 27 which are bent away from each other are and thus form a funnel 28.
  • the funnel 28 is open on the hook 3 out.
  • the opening direction runs approximately parallel to the needle back 25, and the Ground guide surface 16.
  • the Slide springs 11, 12 turn laterally bulbous from each other bent away.
  • the bulge is something like this large, that the distance of the flanks 31, 32 from each other approximately coincides with the funnel outer width W.
  • the Flanks 31, 32 represent those points of the outer surfaces the slide springs 11, 12, which in relaxed State are furthest apart.
  • the outline of the slide springs 11, 12, located in Side view shows is, in particular from Figure 4 can be seen. Both slide springs 11, 12 are at least in their recognizable in Figure 4 area symmetrical to each other educated.
  • the slide springs 11, 12 have a front thread receiving portion 33 which both for opening and closing the thread space as well as for Mesh transfer serves.
  • the length of the thread receiving section 33 agrees approximately with the distance between the Hook tip and the beginning of the slide slot 4 (place 15) match.
  • the point 29 is in the thread receiving portion 33 arranged, the funnel 28 is thus short and the flanks 31, 32 can be found with the thread space closed in the guide region 4a of the slide slot 4.
  • the slide springs 11, 12 are in exactly this area provided with a lower sliding edge 34, which when the Funnel 28 is pushed over the top of the hook, on the bottom guide surface 16 abuts. Starting from this, Rising lower edges 35 gradually to the Schieberfederspitze 39 towards, which in Figure 4 by the measure T2 is indicated. T2 indicates the distance from the ground guide surface to the point 29 at the two free ends 26, 27 of the slide springs 11, 12 touch. The distance between the slider spring tip 39 and the Floor guide surface 16 is designated in Figure 4 with T. This distance is greater than the height T1 of the slot walls 6, 7 in the guide area 4a. That's it possible that the slider tips of the funnel 28 at Slider retraction only in the second further slot area be confiscated.
  • the ends 26, 27 of the slide springs 11, 12 flattened towards the tip 39 ( Figure 6). This ensures the inclusion of the hook tip 3 between the Ends 26, 27 even with advanced wear.
  • the thread receiving portion 33 is followed by a Shoulder 36, which serves for mesh positioning.
  • the Slide springs 11, 12 are following the shoulder 36, as indicated in FIGS. 1 and 2, bent slightly outward, so that corresponding sections with guide surfaces 37, 38 protrude laterally beyond the slide slot 4.
  • the Guide surfaces 37, 38 are oblique to the needle back 25th arranged. Your inclination is about the inclination of the Transition from the bottom guide surface 16 to the sinking bottom area 24 match.
  • Corresponding guide surfaces 41, 42 are as mating surfaces with the same slope Projections of the slot walls 6, 7 formed.
  • the projections form a guide slot for the slide 8, to this in the running area 4b down to the extent lead, that, as Figure 3 illustrates, the thread receiving portion 33, under the slot top edge of the slider slot 4 disappears. This is the distance between the sink bottom region 24 and the top edge of the slot walls 6, 7 greater than the corresponding height of the slide springs 11, 12.
  • the needle 1 is in a needle channel used a knitting machine and leads there reciprocating motion along its needle back 25 out.
  • the Slide 8 moves accordingly against the needle body 2. If the slider 8 is pulled completely into the slide slot 4, to release the hook 3 completely leaves the Slider 8 the guide portion 4a and thus passes completely in the running area 4b, in which he with lower Friction can be shifted.
  • the dimension W ( Figure 6) is smaller or at most only slightly larger than the dimension W2 ( Figure 5). Both needle wear and wear a drive device for the slide 8 is thus minimized.
  • the flared funnel 28 thus hits the hook 3 with great certainty so that the hook 3 finds itself in the hopper 28 without abutting. Also strong lateral acting on the slide 8 Train can not affect the function.
  • the slider springs 11, 12 act in conjunction with the guidance area 4a like a pair of tweezers moving forward of the slide 8 for receiving the hook opens when Pulling back, however, closes again, leaving the slider 8 runs a total of low friction in the slide slot 4.
  • a slider needle 1 is provided with a slider 8, of the two slide springs 11, 12 has. These are in a directly to their insertion funnel 28 arched adjacent area away from each other.
  • the Slider needle has a slide slot 4, the on his entrance 15 is initially relatively narrow, so here a guide area 4a is set. In the connection widens the slide slot 4, so that a running area 4b is fixed.
  • the lateral bulging of the slide springs 11, 12 is dimensioned such that the slide 8 in the running area 4b runs freely and in the guide area 4a is performed without lateral play.
  • the slider needle 1 also works laterally on the slider. 8 acting tensile forces precisely and requires only one small opening width of its funnel 28.
