Definitions

  • the invention relates to a method for producing a knitted fabric on a flat knitting machine with at least one Needle bed with several needles that can be moved lengthways, between which boards can be moved in the longitudinal direction of the needle are arranged.
  • DE 32 47 767 A1 already includes a knitting machine Stitching boards that can be moved parallel to the plane of needle movement known, the stitch formation boards in the first phase of the expulsion movement of the knitting needles in moving in the same direction but at a slower speed to reduce the speed of the needle tongues lessen their opening process.
  • EP-A-0 672 769 also describes a flat knitting machine with slidably controllable in the longitudinal direction of the needle Boards according to the preamble of claim 4.
  • the present invention is based on the object Stitching on a flat knitting machine with the help of Sinkers prevent the knitting thread from advancing the needle jumps out of the needle hook, even if the knitting thread is a has high inherent rigidity, formed from several threads or if several tuck handles are inserted in the needle hook Need to become.
  • the mesh legs are always kept taut, so that the knitting thread does not pop out the needle hook can come.
  • the boards can be controlled individually, so that if necessary only the boards of those Needles that have a correspondingly stiff knitting thread or Process multiple knitting threads simultaneously, be activated have to. With the help of the boards, however, more can be done Achieve advantages. So you can generate at least one enlarged stitch before pulling in the knitting thread Form this stitch by pulling the needle into the needle bed the two boards adjacent to the needle accordingly the desired stitch enlargement are driven out and the needle only up to a standard feed depth for everyone Needles of the needle bed are retracted. So here is the Mesh size no longer solely through a corresponding depth the needle, but by taking one additional expulsion position through the boards.
  • Processes are made with a hole through which extends over the entire length of the needle bed and a tapping wire forming a tapping edge is guided, used and by moving the Circuit boards the position of the tee wire and thus the tee edge for those to be formed with the needle in question Stitch accordingly with respect to the apex of the needle base the desired stitch size and the properties of the knitting thread optimized.
  • By optimizing the knitting will be the most convenient time for the old stitch to slide open depending on the stitch legs of the new stitch the stitch size and material type of the knitting thread.
  • the flat knitting machine according to the invention for performing the Method according to the invention according to one of claims 1 to 3 is the subject of claim 4.
  • the boards can at the same time take on the function of stitch patterns. It However, a mesh pattern can also be arranged next to each board be, the effective surfaces of the stitch patterns and the Boards are identical. Should also be the tee adjustable for the stitches, so the Boards must be provided with a hole through which a extending along the needle bed, serving as a tapping edge Towing wire is guided. The position of this wire can be adjusted by placing the board parallel to the longitudinal direction of the needle is moved.
  • Fig. 1 shows a top view of a needle bed with several Knitting needles 5, 6 stitch patterns and in the longitudinal direction of Needles 5 movable sinkers 3.
  • Fig. 1 a) are the knitting needles in the lowest feed position for the one to be manufactured Mesh size.
  • 1 b) shows three knitting needles 5, which are driven out to the same extent in the direction of the comb are.
  • the boards 3 are in accordance with the propulsion of the Knitting needles 5 also differ in their initial position expelled.
  • Fig. 1 c) is the one State shown in which all needles 5 in comb and the boards 3 are back in the starting position in which they are at the same height as the stitch patterns 6.
  • Fig. 2 1 denotes a needle bed web, the one Has groove 2, in which the board 3 parallel to the needle sliding plane arranged and laterally through the shaft of the needle 5 is fixed.
  • the active surface 4 on the board breast has the same Geometry like the active surface 7 of the dashed line Stitcher 6 on the side of the board 3 lies.
  • the board 3 is by a not shown Cam track on one moved over the needle bed Sled controlled.
  • the cam track exercises one Force K1, which causes the active surface 4 of the circuit board 3 lies in a plane to the active surface 7 of the stitch former 6.
  • the needle 5 is in a needle lock curve of the carriage in In the direction of arrow NE drawn into the needle bed, whereby a stitch loop 9 inserted into the needle hook 8 Knitting thread simultaneously on the knitting surfaces 4 and 7 supported.
  • the previously formed stitch 10 lies with its arch 11 over the legs of the loop 9 and transmits thereby a pull-off force AK one on the loop 9 Knitting device not shown.
  • the needle 5 is in Fig. 2 at the lowest feed position, which is necessary to create the desired mesh size.
  • the needle 5 with the needle lock curve an outward force NV and thus after driven out at the front.
  • the board 3 through the associated control curve with the force K2 at the same speed like the needle 5 driven out.
  • This shifts the active surface 4 of the circuit board 3 is opposite the active surface 7 of the stitch former 6 to the front and holds the legs of the Mesh loop 9 stretched during the forward movement of the needle 5.
  • the board 3 is driven out only until the acceleration jerk the knitting needle 5 by the action of Knitted fabric deduction is compensated and thus the loop 9 solely by the forces of the knitted fabric in the needle hook 8 is held.
  • Fig. 4 it is shown how the needle 5 by the force NV continue to drive out until the ridge equilibrium is reached becomes.
  • the board 3 is by the force K3 assigned board lock curve already retracted, after the knitted fabric trigger ensures that the stitch loop 9 is held securely in the needle hook 8.
  • the feed movement is continued until the front active surface 4 of the Board 3 again in one plane with the active surface 7 of the stitch former 6 lies and the board 3 thus again its starting position has reached. This completes the stitch formation.
  • the in the Fig. 2 to 4 steps performed again.
  • FIG. 5 shows a second embodiment of a circuit board 30 in the same position as the board 3 in FIG. 2.
  • the board 30 is here both mesh patterns and tensioning elements for a loop 90.
  • the board 30 is stored again in a groove 20 of a needle bed web 12.
  • the geometry of the frontal active surface 40 of the board 30 is also identical to the geometry of the active surface 4 of the circuit board 3 Movements of the circuit board 30 and the knitting needle 50 are identical to those of the board 3 and the needle 5.
  • the board 30 is thicker than the board 3, preferably as thick as the board 3 and the stitch patterns 6 together.
  • the mesh size cannot only by a corresponding retraction depth of the knitting needles 5 or 50 can be influenced, but also by sprouting of the boards 3 and 30 would be the board 3 in Fig. 1 something expelled further forward, so that would become larger Form stitches because the knitting thread around the sinkers 3 must be drawn in. So with a constant feed depth the needles 5 and 50 by a corresponding expulsion position the sinker 3 or 30 affects the mesh size become.
  • Fig. 6 shows a further variant of a circuit board 3 ', which again is stored in a groove 2 'of a needle bed web 1'.
  • the Chest surface 4 'of the board 3' serves as a mesh.
  • the board 3 ' has a bore near the chest surface 4', through which a tapping wire 14 is passed.
  • the tee wire 14 extends over the entire length of the needle bed and forms a teeing edge.
  • the foot 15 of the board 3 ' is again acted upon by a circuit board lock curve.
  • Shown in Board position is the foot 15 so acted that the stripping wire 14 is in a basic position GP, the for the machine fineness in question for the Production of meshes of normal size with an average Knitting thread an ideal distance from the apex of the Of the needle base SNG.
  • the position of the tapping wire 14 can be adjusted accordingly Move the board 3 'in the direction of the arrow + or in Arrow direction - can be changed to create ideal conditions for knitting.
  • the adjustment can the position of the knock-off wire 14 take place with pinpoint accuracy. This is important when knitting within a knitted fabric Sections of mesh of different size or different Knitting yarn is used.
