With increasing increases in rotational speeds in circular knitting machines and simultaneous multiplication of the knitting systems, however, the described advantage proves to be a weak point for production safety.
  • the advantages of the reed needles technology as a functional unit with the advantages of the needles and at the same time to avoid the disadvantage of having to use an extra controlled complementary element in user-friendly size in the machine is in the DE 10 2007 039 973 .
  • a vibrating-needle technology is provided in which the long shaft of the slider element is transformed into a mini-board member reciprocating within the needle. This is moved in phases along with the needle and on the other hand by the Machine controlled phased stopped. From the point of view of implementation, the longitudinal guide is always more complex than the fulcrum bearing of a component.
  • the board should have a leadership approach and be secured with tongue and groove laterally against falling out of the needle shaft smoothly, which limits the fineness of execution in addition to these difficulties in mass production.

  • the needle body 41 can either be offset on both sides in front, so that the mesh section 42 introduced above is laterally flat, or as shown, are placed on the shaft of the needle body 41 adapted to the interior of the U-shaped mesh section 42. It is then expedient to provide a small U-bracket in the region of the foot in order to stabilize the weaker shaft of the needle body 41 as it moves in the needle channel.
  • Fig. 39 is the representation of the needle body 41 and the small stabilizing U-bracket for the needle foot for movement in the needle channel of the textile machine, wherein just in the needle body 41, a recess for receiving the transmission tongue 43 is provided.
  • Fig. 40 is the side view of the U-shaped bracket of the mesh section 42, in which the two-sided course of the flat sides merges forward into the chest and hook halves (polished steel surfaces instead of milled surfaces).
  • the lower edges are welded to the lower edge of the needle body 41 by laser technology. In this case, in particular a laser weld seam can be formed for connection.
  • Fig. 41 is the side view of the transmission tongue 43, which has just the transmission finger 12 and the shaft below the retaining tooth 45.
  • Fig. 42 is the view of the development of only flat board of the U-shaped bracket of the mesh section 42 in Fig. 40 with stop breakthrough 44 for the holding tooth 45. From there above and below, a narrow zone of the central axis is soft annealed by laser technology, so that the U-bend to the mesh section 42 can be performed.
  • the stop breakthrough 44 may be formed so that it the relative movement of the transmission member or the transmission tongue 43 to the base body upwards or forwards, ie in the direction of the needle hook, and / or down or back, ie in the direction of the needle foot , limited. This limitation is achieved by an interaction of the Antschticians 44 with the holding tooth 45th
  • Fig. 43 Below shows the view from the front of the split needle head, which was welded in the base area and in the area of the transfer finger 12 a this adapted having a bent bed and Fig. 43 Above shows the view of the split side surfaces of the mesh section 42, which are welded together unifying front and just, not visible, form the receiving bed for the transfer finger 12.
  • the needle hook thus has two halves, the two halves being separated by a gap.
  • FIGS. 44 to 47 is the mesh transfer to a needle of the other needle bed of a flat knitting machine, without having to make complicated effort on the needle, can be seen.
  • the two needle beds are brought to each other in the alignment position of the needle channels and in the Fig. 44 the donor and the accepting needle are shown in the starting position, each with a loop in the needle hook.
  • Figures 48 to 50 show the representation of the stitch forming center of the significant pulp production of a warp knitting machine.
  • the needles are not housed individually movable in needle beds, but firmly clamped in so-called needle bar in a certain division. To stitch, all needles move together. Patterns that are based on the basic functions of knitting, non-knitting and tufting are not possible here.
  • Parallel to the needle bars, the needle closing elements are provided in a second bar system in the machine. This requires many functional parts in a confined space.
  • the use of laser technology based function needle with two-piece hook after the FIGS. 38 to 43 avoids the second ingot. Instead of this occurs over the bar length provided holding rocker 50, which the effect of in FIGS. 16 and 17 shown retaining projection 18 on the bump 14 takes over. Instead of the recesses in the holding projections 18, the pivoting of the holding rocker 50 occurs.
  • the Fig. 48 shows the needle bar B in the upper position.
  • the recorded in a fixedly connected to the machine bearing rail 51 holding rocker 50 is pivoted and its retaining projection 18 is located under the bump 14 of the transmission tongue 43rd
  • the holding rocker 50 can be provided continuously over the entire length over which the needles are arranged.
  • the pivoting movement of the holding rocker 50 is synchronized with the up-and-down movement of the needles.
  • Fig. 49 the needle bar B was swung back and thereby closed by stopping the hump 14 on the transfer member 43 of the needle hooks. Thereafter, the holding rocker 50 is swung out, so that in the further downward movement of the bump 14 on the retaining projection 18 is moved past how the Fig. 50 in the lower needle bar position represents.
