Definitions

  • the invention relates to a punched knitting tool for textile machines, in particular knitting and warp knitting machines with a shaft in which at least one free space is formed is on its edge, at least in places, lined with at least one area of reduced shaft thickness and filled with a heterogeneous material is that is firmly connected to the shaft and in the area reduced shaft thickness protrudes.
  • tongue needles Under “knitting tools” are tongue needles, point needles, Pushpins, needles without tongue, for example plush hooks for the production of plush goods and boards and to understand the like.
  • punched knitting tools are known in their shank at least one free space, for example in the form of an elongated hole is formed, the longitudinal axis of which is parallel or coaxial is aligned to the longitudinal axis of the shaft.
  • This freedom is with a vibration damping heterogeneous material filled in, which is firmly connected to the needle shaft.
  • this material is an elastic plastic material with high damping properties, but the Use of other materials is not excluded is.
  • the object of the invention is to remedy this and a To create knitting tools of the type mentioned at the beginning, that with perfect, positive anchoring of the respective free space in the shaft, heterogeneous material due to high dimensional accuracy and simple Manufacturing possibilities distinguished.
  • the knitting tool according to the invention the features of claim 1.
  • This knitting tool is at least on the edge of a free space, at least in places, the area reduced shaft thickness provided that a cross-sectional shape with a starting from an area minimal thickness on the side of the shaft, closer to one area of maximum thickness increasing in the free space Has thickness dimension.
  • the cross-sectional shape of the edge area with reduced Shaft thickness is usually at least approximate trapezoidal, but are also other cross-sectional profile shapes conceivable.
  • the marginal area of reduced shaft thickness is advantageously stamped into the shaft, whereby it be profiled tooth-like at least in sections can.
  • the edge area of reduced shaft thickness at least is profiled in sections, tooth-like.
  • the latch needle shown in FIGS. 1, 2 has a needle shaft 1, which is usually made of steel strip is punched out and two molded on top Feet 2 carries and on one side a needle head 3 with a needle hook 4. The one with the needle hook 4 interacting needle tongue is indicated at 5.
  • the needle shaft 1 are in the illustrated embodiment 4 spaced apart in the axial direction, continuous slots 6 punched, each of which forms a free space, which with a heterogeneous Material 8 is filled out.
  • the heterogeneous material is with the shaft 1 along the edge of each slot 6 firmly connected.
  • It s usually made of a plastic, preferably a polyamide -12, polyurethane, polyethylene or polytetrafluoroethylene or the like, but are including in principle non-organic substances, e.g. understood metallic type.
  • Each slot 6 is through on its long sides two mutually parallel webs 9, 10 and on the end face by two from the upper edge 11 of the shaft to the lower edge 12 continuous guide parts 13 limited.
  • Each foot is 2 each supported by one of the guide parts 13.
  • the both on the upper needle shaft edge 11 and on the lower needle shaft edge 12 lying webs 9, 10 have a low height of preferably about 1.1 mm and less. Their length is advantageously more than 8 mm. The invention however is not on knitting tools with these dimensions limited.
  • the outline is each slot 6 on the two webs 9, 10th adjacent long sides by essentially straight Lines 14, 15 delimited by two at the end faces approximately elliptically curved lines 16, 17 connected to one another are.
  • each of one of the elongated holes 6 formed free space is the shaft 1 in the area of the two webs 9, 10 on both sides with one narrow, strip-shaped edge area of reduced shaft thickness provided, which is designated 20.
  • the edge area shows from FIGS 20 reduced shaft thickness a cross-sectional shape based on an area 21 of minimal thickness on the side of the shaft 1 to a closer to that of the Elongated hole 6 formed area 22 maximum Thickness increases in its thickness dimension.
  • the illustrated embodiment is the cross-sectional shape of the edge region 20 of reduced shaft thickness apparently approximated trapezoidal, with the respective Bridge 9 or 10, followed by a shorter baseline.
  • the size this bevel angle 24 of the edge region 20 "Negative puncture" thus formed depends on the requirements and the geometric conditions of each Knitting tool. The angle is usually 24 in a range of approx. 5 ° to 60 °.
  • Thickness dimension is the one shown Embodiment at about 60% of the shaft thickness 26. In the Practice has depended on the circumstances of each Knitting tool, a minimum thickness range of about 20 to 80% and more of the shaft thickness 26 as appropriate proved.
  • the thickness (FIG. 5) in the area 22 of the largest thickness dimension is about 70% of the Shank thickness 26.
  • the thickness dimension in this area is 22 maximum Thickness preferably between about 40% and 95% of the shaft thickness 26. In any case, the maximum thickness is 22 smaller than the shaft thickness 26, so that a safe anchoring of the plastic material filling 8 in the edge regions 20 remains guaranteed.
  • the marginal areas 20 of reduced thickness protrude into the Plastic filling 8, in which they are embedded, wherein the projecting retaining teeth 19 an additional positive Anchoring.
  • edge regions 20 described are reduced Shaft thickness is used in the manufacture of the latch needle stamped the shaft 1. This happens practically in the Way that from the band steel at each latch needle first the elongated holes 6 with the through the holding teeth 19th given contour are punched out. These elongated holes 6 are, as already explained, on their two opposite Long sides through the essentially straight Lines 14 and 15 (with the projecting retaining teeth 19) and at the end by one of the two straight lines 14, 15 interconnecting, essentially elliptical Outline 16 or 17 limited.
  • FIG Embossing tool consisting of a die 29 and one of these assigned stamp 30 there.
  • the die 29 and the embossing stamp 30 have mutually facing embossing surfaces 29a or 30a, which are recessed in a roof shape and consist of two flat surface sections, each enclose an obtuse angle 31, the Size results from the bevel angle 24 ( Figure 5).
  • the axial length of the die 30 (and die 29) is shorter than the length of the associated elongated hole 6. It extends in the longitudinal direction only between the two semicircular arches entered with dashed lines in FIG. 3 28. This means that those in the shaft 1 embossed areas 20 of reduced shaft thickness only on the opposite long sides of the Elongated hole 6 between the two designated 32 Boundary lines that lie approximately at the point that of the respective end stop tooth 19 in the elliptical arch 16 or 17 merges.
  • the tongue needle blank punched out of the strip steel and its other Processing supplied in the course of which Plastic filling 8 is introduced into the elongated holes 6. Since the areas 20 of reduced wall thickness do not overlap the ellipse arches 28 on the end faces of the elongated holes 6 extend, the plastic is not on these end faces positively connected to the shaft 1. This has been in particular on the oblong hole end faces facing a foot 2 proven to be useful.
  • the one measured perpendicular to the longitudinal axis 34 of the shaft Width of one of the areas 20 of reduced shaft thickness is typically about 0.1 to 0.5 mm, preferably about 0.2 mm.
  • the invention is not limited to but on open spaces with any, each Appropriate outline shape of the edge applicable. "Open spaces” also includes open-cut sections etc. understood in shaft 1.
