Definitions

  • the innovation relates to a punched knitting tool for textile machines, in particular knitting and warp knitting machines, with a shaft which carries at least one foot and has at least one space filled with a vibration-damping plastic, the plastic filling of which is firmly connected to the shaft.
  • knitting tools are latch needles, point needles, sliding needles, needles without tongues, sinkers and the like. To understand.
  • DE-PS 28 20 925 At least one coupled to the foot, to provide a slightly flexible bridge in the shaft and thus to convert the impact energy introduced into the foot through the lock parts of the machine into bending work.
  • This narrow web has a maximum height of 1.1 mm and is therefore highly elastic with a length of more than 8 mm, for example.
  • the innovation is based on the object of further improving a knitting tool of the type mentioned at the outset, which is set up for high knitting speeds in the sense that it maintains the described advantageous properties in mass production, simpler conditions with regard to the anchoring of the respective free space in the shaft filling plastic.
  • the knitting tool is characterized in accordance with the innovation that the shaft, starting from the upper and / or lower edge of the shaft in its longitudinal direction, is at least partially provided in its longitudinal direction with at least one slit-like depression, through which the free space filled with the plastic is formed.
  • the plastic is held on all sides in this slot-like depression, so that an excellent anchoring to the metallic shaft is easily ensured.
  • the depressions forming the free spaces can be designed accordingly Slot cutters can be easily manufactured.
  • the depression is delimited on both sides by relatively thin cheekpieces which hold the knitting tool elastically, so that in conjunction with the vibration-damping plastic filling the depression, the advantageous properties explained at the outset, ie low hook or head breakage frequency and long service life maintain high knitting speed or even further improve it.
  • the shaft can advantageously have at least one free space, at least in some areas continuous from the upper edge of the shaft to the lower edge, which, for example, has at least one projecting or recessed area on at least one side, so that there is additionally a positive anchoring of the plastic material. Pressing the plastic into such a continuous slot-like depression is also particularly simple. Basically, however, embodiments are also conceivable in which the shaft has at least one free space closed at the bottom, which is then only filled with the plastic from its opening on the upper or lower edge of the shaft.
  • the shaft of which has at least two guide parts which are continuous from the upper edge of the shaft to the lower edge of the shaft and which are connected to one another by narrow webs, through which a free space filled with the plastic is limited together with the guide parts, the arrangement is advantageously made such that a slot-like depression of the type described is arranged in the area of at least one web, the free space thus formed is also filled with plastic.
  • the height of the web can depend on the shaft dimensions, taking into account the damped vibration behavior to be achieved; however, in the preferred embodiments it is at most 1.1 mm.
  • the knitting tool shown in FIGS. 1 and 5 in two different embodiments, punched out of a steel band, only the shaft 1 is illustrated, which in each case carries a molded foot 2 in both embodiments.
  • the knitting tool is, for example, a latch needle, the neck and head part (not shown) of which is formed in a manner known per se.
  • the shaft 1 is designed as a so-called full shaft. It is provided in the area in front of the foot 2 with at least one slot-like recesses 3 which extend in the longitudinal direction of the shaft and which is limited to the area of the shaft shown in FIG. 1.
  • the slit-like depression 3 extends from the upper edge 4 of the shaft to the lower edge (back of the shaft) 5; it is arranged symmetrically to the longitudinal central plane of the shaft 1 indicated at 6 in FIG. 2 and, as can be seen in FIGS. 1, 3, was milled in with suitable slot cutters, starting from the upper shaft edge 4 and the lower shaft edge 5.
  • the slot-like recess 3 is delimited on its two end faces by gusset-like material projections 7 which protrude into the free space formed by the recess 3 in the shaft 1.
  • This free space is completely filled with a plastic material designated by 8 in FIGS. 3, 4, which just ends with the upper edge 4 and the lower edge 5 of the shaft and which is firmly connected to the shaft material delimiting the free space.
  • the remaining cheek pieces 9 which delimit the free space formed on the broad side by the slot-like depression 3 are relatively thin, so that there is a high elastic flexibility of the shaft 1, which is damped by the plastic material 8 filling the free space.
  • a slot-like depression 3 is shown.
  • several such depressions 3 are provided, which can also be arranged in front of and behind the foot.
  • the shaft 1 has continuous guide parts 10, 11, 12 from the upper shaft edge 4 to the lower shaft edge 5, which are each connected to one another by two parallel, opposing narrow webs 13, 14 from which are the webs 13 on the upper shaft edge 4 and the webs 14 on the lower shaft edge 5.
  • the plastic 80 is firmly connected on the edge to the edge of the opening 15 or 16; it fills the breakthrough formed free space completely.
  • two slot-like depressions 30 are formed in the shaft 1 in the region of the two openings 15, 16, which also extend in the longitudinal direction of the shaft and are arranged symmetrically to the longitudinal center plane 6 (FIG. 6) of the shaft.
  • the two slot-like depressions 30 penetrate the upper webs 13 and run through the lower webs 14 without them emerging from the shaft 1 in the region of the lower shaft edge 5. Their outline is indicated by dashed lines in FIG. 5 and its exact shape can be seen in FIG. 7.
  • the slot-like depressions 30 are in turn filled with the plastic 80, which merges into the plastic filling of the openings 15, 16. As can be seen from FIG.
  • the slot-like depressions are profiled on the end face again in such a way that protruding gusset-like areas 7 and undercut areas 17 are present in the free space formed in each case by the depressions 30, which bring about a positive anchoring of the entire plastic filling.
  • At least one of the slot-like depressions 30 could also extend through the lower web 14 and thus open in the region of the lower shaft edge 5.
  • Each of the slot-like depressions 30 extends essentially over the entire length of the web 13 penetrated by it. It is milled into the shaft 1 with a slot cutter and thus at least partially curved in a circular manner in the region of its lateral edges.
  • a typical shaft thickness for the knitting tools described is approximately 0.4 mm.
  • the width of the slot-like recess 3 or 30 is approximately one third of the shaft thickness, although other width / thickness ratios are naturally also conceivable.
  • a polyamide is particularly suitable as the plastic for the plastic filling 8 or 80.
