Definitions

  • the invention relates to a latch needle for a stitch-forming machine, in particular for a knitting machine for producing textile surfaces.
  • latch needles are used in machines, in particular in knitting machines, which are moved back and forth in rapid succession during operation.
  • the provided on such a latch needle tongue opens and closes in rapid succession and at high speed a receiving space for the thread.
  • the tongue head When changing the tongue from closed position to reserve describes the tongue head a circular arc-shaped swinging motion.
  • the tongue beats in rapid succession alternately on the hook to form the closed position and on the Shaft of the latch needle, to form the open position or reserve.
  • the receiving space of the thread is bounded by a needle body and its one-end hook in cooperation with the opening and closing tongue.
  • tongue-glazed needles are used to form the stitch
  • the tip of the hook plunges into a depression in the tongue head.
  • the tip of the hook is almost completely covered by the tongue head. This facilitates the knocking off of half stitches over the tongue head and thus the stitch formation.
  • knocking off the semi-mesh slides from the top of the needle over the tongue shaft and then over the tongue head.
  • the relatively wide tongue head facilitates the interaction of tongue and hook by the tongue head hits the hook safely even with greater tongue bearing tolerance.
  • the latch needles are slidably held in a needle carrier while being reciprocated in the longitudinal direction by cams for loop formation.
  • the shaft width of a latch needle is slightly smaller than the width of a needle channel associated with it. Due to the existing manufacturing tolerance of the needle channels and the needle shank width, it is possible that a latch needle, influenced by the rotation of the needle carrier of a circular knitting machine, with respect to the center axis of a guide channel, inclined thereto.
  • the knitting machine needle and its tongue each undergo a deflection relative to their ideal position. These tolerances increase due to wear with increasing duration of use of the knitting needle, with the result that also increases the lateral deflection of the tongue.
  • knitting machines which have little space between the needles and boards for the passage of the tongue in their swinging motion, it may thus lead to contact between the tongue head and a board adjacent to him. Both the board and the tongue head experience wear, which is disadvantageous.
  • hook-pointed latch needles have been proposed. So revealed the DE OS 28 34 558 a knitting needle whose hook has a relatively deep trough in the area of the tip. This trough receives a portion of the tongue spoon, being bounded by two side surfaces arranged at an acute angle to each other, which partially overlap the tongue spoon of the tongue when the tongue is in the closed position.
  • the width of the tongue is less than the width of the hook and thus substantially less than the width of the needle shank.
  • this has the consequence that the half-stitch during stripping on the part of the hook tip, which is not covered by the tongue head, strips and gets stuck in the worst case, whereby the tee-off process is interrupted. This in turn has a negative effect on the stitch formation.
  • a solution for this will be in the DE 100 57 765 disclosed.
  • This solution is used in many cases, with the increased due to the projection increased mass of the tongue, especially in high-speed knitting machines, as disadvantageous.
  • an object of the invention to provide an improved latch needle for a stitch-forming machine having a tongue with a tongue shaft which is pivotally mounted on a bearing means and carries a tongue head, which is provided with a receiving space for receiving the tip of the hook.
  • Such needles are in the WO 02/08506 A , of the US 3,728,874 A or the EP 0 077 022 A shown graphically with a width of the tongue head, which is smaller than the width of the needle shaft.
  • latch needle which has the smallest possible tongue spoon whose tongue head has a width smaller than 95% of the width of the needle shank. This allows the half-stitch to experience minimal expansion when knocked off as it slides over the relatively narrow tongue head.
  • the distance to the adjacent part (board) due to the reduced compared to known latch needles width of the tongue head, the distance to the adjacent part (board) and thus reduces the risk of contact between the board and the tongue head.
  • the formation of sharp-edged edges on the tongue head is avoided. There are no sharp edges that could damage threads used to form stitches. In particular, the otherwise possible worst case severing of filaments, i. the generation of a faulty goods, with appropriate fault lines avoided.
  • the latch needle according to the invention combines the advantages of the hook-toothed needle with the advantages of the tongue-stained needle.
  • the latch needle according to the invention has a tongue whose tongue head is delimited by two surface areas arranged parallel to one another, in the form of facets. The distance of these side surfaces forms the width of the tongue head.
  • the side surfaces are arranged in parallel to an imaginary by the central axis of the tongue or the knitting machine needle level extending in the tongue longitudinal direction.
  • the transition of the side surfaces in the tongue head back is edge-free, ie formed rounded. This ensures a smooth sliding of the half stitch over the closed tongue back.
  • Opposite the back of the Tongue's head is formed a hollow, a so-called Zasche.
  • This zipper receives at least a portion of the tip of the hook of the latch needle and is preferably adapted to its geometry.
  • the zapping of the tongue head is a Image, for example, in the sense of an inverse or negative shape of the tip of the hook.
  • the transition from the relatively narrow tongue shaft to the tongue head is formed by two facets. These are arranged divergently in the tongue longitudinal direction as in a conventional latch needle. In addition, further facets may be arranged at the transition region from the tongue shaft to the tongue head, which allow a special design of a receiving hopper in the tongue shaft.
  • the tongue shaft is limited in its width by two side surfaces which are oriented parallel to each other.
  • the tongue shaft is mounted on a bearing device in the tongue slot of the knitting machine needle.
  • This bearing device may be formed as a separate axle by means of an axle pin or as a pin or half-pin, which is formed from the sheep cheeks. So that the necessary ease of the tongue is ensured in the tongue slot, the side surfaces of the tongue shaft can be arranged at an acute angle to each other in the direction of the tongue.
  • the tongue shaft can thus be slightly wedge-shaped. Its width then decreases in the direction of the tongue-head. The reduction of the width is limited to a few thousandths of a millimeter.
  • the side surfaces of the tongue shaft are then arranged at an acute angle to each other, wherein the opening direction of the angle is oriented away from the tongue head.
  • the side surfaces of the tongue head are arranged only in the vertical direction parallel to the side surfaces of the tongue shaft.
  • the imaginary extension of the side surface of the tongue head then forms with the adjacent side surface of the tongue shaft, an acute angle greater than zero degrees.
  • the opening direction of the angle is oriented in the direction of the tongue head.
  • the side surface of the tongue head encloses an obtuse angle smaller than 180 ° with the side surface of the tongue shaft.
  • the tongue slot in which the tongue shaft is movably mounted, is arranged in the longitudinal direction of the knitting machine needle and is preferably located in the center of the needle shaft with respect to the needle width, which is measured in the needle transverse direction. It is bounded by two mutually facing side surfaces which are formed on the shaft walls of the needle shaft and between which the slot width is to be measured. Between the shaft walls of the tongue slot is arranged.
  • the width of the needle shank is measured perpendicular to its side surfaces. This shank width substantially coincides with the width of the needle receptacle in the knitting machine or is slightly smaller, so that the longitudinal displacement of the knitting machine needle is ensured.
  • the width of the tongue head is preferably substantially smaller than the width of the needle shaft.
  • the width of the latch head is 80% of the width of the needle shank, with the reduction in travel already afforded by the reduction of 5% of the tab head width from the width of the needle shank.
  • the tongue tongue width is between 70 and 90% of the width of the needle shank. This ensures that there is sufficient space between the side surface which delimits the tongue head and the part of a knitting machine adjacent to the side surface during the oscillating movement of the tongue.
  • a tongue head according to the invention is due to its shape.
  • the mutually parallel side surfaces of the tongue head provide in the case of contact with another part of a knitting machine a planar system. This is less susceptible to wear compared to a punctiform contact point and any wear is less. Thus, the risk that sharp edges arise in the area of the tongue head is considerably reduced.
  • the needle hook has a tapered tip. This is formed in the shape of a tapered cone. This cone tapers from the hook cross section to the tip. The tip is rounded so that contact with the thread on the latter leaves no damage.
  • FIG. 1 a latch needle 1 is illustrated, which has a needle body 2 with a stitch-forming part 3 at the end a hook 4 is formed.
  • the hook 4 ends in a tip 14.
  • the needle body 2 has at its stitch-forming part 3 a tongue slot 5, in which a tongue 7 projects with one end 15.
  • the tongue 7 is held in the tongue slot 5 on a bearing device 6 and pivotally mounted.
  • the storage device 6 is z. B. formed by a tongue slot 5 by cross-bearing axis. This bearing axis may be formed in the form of a bearing pin or preferably in the form of a one-piece or multi-part with the needle body 2 seamlessly connected pin.
  • To this storage device 6 is the tongue 7, from the in FIG. 1 Closing position illustrated on the left, in a reserve in FIG. 1 illustrated on the right side, hinged. When changing from the shooting position to the open position, a hook interior 10 is closed or opened.
  • the tongue 7 has a narrow, preferably parallelflankig limited shaft 8, the width of which is slightly smaller than that of the tongue slot 5.
  • the length of the tongue 7 is dimensioned so that it can reach the top of the hook 4 with its end 23 and partially overlaps ,
  • the end 23 is provided on the hook 4 side facing a concave molding surface 25, according to the embodiment of FIG. 1 a trough 12 for receiving at least a portion of the hook 4 forms.
  • the mold surface 25 may correspond to the shape of the top 17 of the hook tip 14 and be adapted.
  • the overall configuration is such that the trough 12 exclusively a portion of the conical tip, but not other sections of the hook 4 receives.
  • the formation of the end 23 of the tongue 7 is further from the Figures 2 . 3 and 4 out.
  • the end 23 has a back surface 24, which forms the back of a end formed on the tongue 7 spoon. This spoon marks the end 23 of the tongue 7.
  • Its width 16 exceeds the width BS of the substantially parallel flank tongue shaft 8 (FIG. FIG. 3 ).
  • the tongue head width 16 is determined by the distance between a first side surface 21 and a second side surface 22 of the tongue head 9 and measured perpendicular to this. It exceeds the width BS of the tongue shaft 8.
  • the width BS of the tongue shaft 8 which is measured perpendicular to the flat sides 27, 28, increases steadily in the transition region until the width 16 of the tongue head 9 is reached.

  • the tongue head 9 has a trough or a receiving space 12, which, when the tongue 7 is in the closed position, at least part of the tip 14 of the hook 4 receives.
  • the receiving space 12 and the hook tip 14 are adapted to each other so that the front portion of the hook tip 14 almost completely immersed in the receiving space 12. This makes it possible that a thread without obstacle in the hook interior 10, slides under the hook tip.
  • the lower part of the hook tip 14 does not form, with respect to the lower edge of the tongue head 9, protruding edge when the tongue is in the closed position ( FIG. 2 ). This makes it possible that a thread can slide without resistance into the hook interior under the hook tip and does not get caught on one edge.
