  • the lock parts doing for each of the possible needle movements to stitch or Form tuck handles, to pass stitches, to take stitches and for the simultaneous transfer of stitches and take over one separate control curve for optimal positioning of the associated Form the circuit board. So there are a total of four separate ones Control curves for the boards exist, depending on the associated one Needle movement can be selected. So that can be Manufacture knitted pieces in a quality that was previously hardly possible was achieved.
  • lock parts can have one or more additional ones Cam tracks for board opening movements that are not due to needle movements but for other items like Thread guides or engagement elements are required. Such opening movements of the boards are, for example necessary to avoid collisions with thread guides.
  • the knitting machine can use selection elements for selective Activate only those boards that are needed exhibit. With the previous flat knitting machines however, all boards moved together.
  • the boards can be pivoted in a manner known per se be arranged, where they are also continuously between a maximum Open position and a maximum closed position can be pivoted.
  • a maximum Open position For proper functioning of the boards it is also advantageous if the boards held in their maximum open position by springs if their control surfaces are not through the cam tracks be charged. This ensures that the boards are always in a defined rest position are.
  • the springs can be made in one piece with the boards, preferably be designed as spiral springs.
  • the boards of the front and rear needle bed can be identical trained and can be brought into identical closed positions his. But it is also possible to remove the boards from the front and to design the rear needle bed differently and / or them to move into different closing positions.
  • the shape of the hold-down boards can be selected differently become.
  • the boards can have an effective area that consists of several sectors composed, one sector on the mesh of the associated Needle bed and a sector on the stitches below the Tact wires acts.
  • the board can also be a sector have on the stitches of the opposite needle bed acts.
  • Fig. 1 In the sectional view in Fig. 1 are the front needle bed 1 and the rear needle bed 2 of a flat knitting machine in the Mesh formation area shown. Next to the needles 4 are stitch patterns 3 and hold-down boards 10 are arranged. Along the needle beds 1 and 2 are also tapping wires 5 for the Mesh tensioned.
  • the hold-down boards 10 have a selection element 20 a selection slider 23 on in the direction of the double arrow 50 is movable.
  • a movement device not shown can create different cam tracks of a cam track set 30, the effective area of the selection element 20 act on the board 10 in the direction of the double arrow 40, are adjusted so that they can be selected via the selection element 20 the hold-down board 10 in different closing and Can pivot opening positions.
  • the selection element 20 is in the selection position in Fig. 1, so that the cam set 30 can act on the hold-down board 10. Via a selection device, not shown, the element 20 via the selection slider 23 in this position a rest position shown in FIG. 4 shifted out.
  • the Hold-down plate 10 is pivotally mounted about an axis 6. The pivotal movement is by a round rod 7, the leads through a curved slot 12, limited.
  • the largest possible Opening position of the hold-down board 10 is by the stop surface 13 of the elongated hole 12 is limited and the largest possible Closed position through the stop surface 14.
  • Die Hold-down plate 10 forms a leg spring 11 with a Unit.
  • the leg spring 11 lies with a contact surface 11.1 under tension on a round rod 8, whereby the Surface 13 of the elongated hole 12 held in contact with the round rod 7 the hold-down board is in its maximum opening position is fixed.
  • the connected to the hold-down board 10 longitudinally displaceable Selection element 20 is through the selection slider 23, the by a selection device, not shown, in the direction of the arrow 51 was applied, moved to the selection position that is, within the sphere of influence of the cam track set 30 on a control surface 21 of the selection element 20 rests.
  • the control set 30 consists of cam tracks 31, 33, 35 and 37 together, which cause the closing movement of the circuit board 10. Are located between the cam tracks 31, 33, 35 and 37 there are boundary tracks 32, 34 and 36 that define the board opening limit.
  • the cam track 31 can be the optimal one Movement of the board 10 in the formation of stitches and Catch handles, the cam track 33 the optimal movement for Pass stitches, pass cam 35 for stitches and takeover and take the cam 37 for stitches cause.
  • the limiting path 32 is the control curve path 31 assigned, the limiting path 34 of the cam path 33 and the boundary track 36 of the cam track 35.
  • a further cam track 40 is also shown, which by a compression spring 41 in the direction of arrow 42 is applied.
  • This cam track 40 causes a board opening movement, which are not in the functional context of The needle movement path is available and how it is made possible, for example a thread insert by the thread guide is required is.
  • FIG. 3 shows a sectional view corresponding to FIG. 2 the action of the control curve path 31 and the limiting path 32 on the control surface 21 of the selection element 20.
  • the control curve path 31 and the associated boundary path 32 are by a device not shown in FIG Arrow directions 41 and 42 have been moved. This leads the Circuit board 10 pivots about axis 6 until the Surface 14 of the elongated hole 12 comes into contact with the round rod 7, the board 10 in its maximum closed position located.
  • the limiting path 32 serves the opening movement the board 10 as detailed in FIG. 8 is shown. Both the control curves 31 and the limitation curves 32 can be moved continuously, which means always generate the optimal trajectory for the boards 10 leaves.
  • FIG. 4 shows a representation corresponding to FIG. 2 the board 10 in its rest position.
  • the selection element 20 is in the idle position via the selector slide 23 in the direction of arrow 52 been postponed.
  • the control surface 21 is no longer under control curve set 30, so control cams 31, 33, 35 and 37 no longer the board 10 can influence.
  • the control cam track 40 can also now do not act on the circuit board 10, since the associated Effective surface 22 of the selection element 20 also downwards has been postponed.
  • circuit board 10 is an active surface 15, which consists of several sectors 16, 17 and 18 composed.
  • the active surface 16 acts on the mesh of the rear needle bed 2, to which the hold-down plate 10 belongs, on.
  • Section 18 acts on the stitches are located below the tapping wires 5.
  • Sector 17 on the The tip of the board 10 acts on the mesh of the opposite Needle bed 1 on.
  • the cam track 31 is also like this molded that also concerns that are not directly related to stitch formation related, can be fulfilled. So be in sector 70 the hold-down boards are only in the closed position for this reason brought with it threads that are floated over several needles in the needle hook of the first needle, which forms stitches from this thread, can be inserted. In Sector 80 'initiates a closing movement for this and in Sector 90 'an opening movement.
  • FIG. 7 shows the example of a needle cam track 60 and one associated cam track 33 for passing stitches on the needles of the opposite needle bed.
  • the direction of movement the curved tracks 60 and 33 again run in Arrow direction 55.
  • the center axis of the system is designated by 65.
  • the hold-down boards moved by the cam track 33 10 only have to meet the requirements of passing the stitch. Therefore, the sector 70 in which the hold-down boards are located must be optimally designed in the closed position.
  • sector 80 in which the closing movement is initiated.
  • sector 90 the opening movement initiated. 6 and 7 are superimposed in such a way that the central axes 65 are congruent is clear the shift of sectors 70 (circuit board closed), 80 (initiation of the closing movement) and 90 (initiation of the Opening movement) of the control curve 31 compared to the sectors 70, 80 and 90 of the control curve 33.
  • FIG. 8 shows the interaction using the example of the cam track 31 this cam track with a limiting track 32 for the board opening movement.
  • a not shown Movement device is the cam track 31 in the direction the arrow 41 brought into the working position. Because of their contours the sequence of the board control is rigidly specified.
  • the closing depth of the circuit board 10 is determined by how far the cam track 31 is moved in the direction of arrow 41.
  • the boundary track 32 is parallel to it in the direction of Arrow 42 by the movement device, not shown in Position brought. She limits with her Area 32 'the largest possible opening movement 31' 'as they actually allowed according to the contour of the cam track 31 would.
