Definitions

  • the invention relates to a device for transferring needle stitches in flat knitting machines, in particular when the knitwear width is reduced or increased.
  • the stitch-transfer device according to the invention should have a particularly simple construction and a safe mode of operation.
  • the two neck combs are displaceable in their longitudinal direction independently of one another, they can be selected with their neck fingers as desired for the stitching and accordingly in Stitch delivery position raised needles are set, even if they are asymmetrical to the center of the needle bed.
  • the two, swung-over neck combs are then advanced together in the direction of the needle bed, their neck fingers, which lie opposite the needles raised in the stitch-dispensing position, reaching through the loops carried by these needles.
  • the raised needles are then lowered and thereby transfer their stitches to the neck fingers.
  • the two neck combs are then swiveled up, thereby lifted out of the needle bed and then adjusted with their stitch-carrying neck fingers with respect to the needles which are still lowered and which are supposed to take up the neck-and-loop stitches.
  • the neck combs are then pivoted away and advanced towards the needle bed so far that the stitches they carry come to lie in the path of movement of the needles intended to take up the stitches. Then these needles are driven out and remove the stitches from the shoulder fingers.
  • the swung neck combs are then pulled back from the needle bed into their starting position, in which a new stitching can be initiated.
  • the movements of the neck combs of the mesh neck device according to the invention can be achieved with the aid of any guide and drive means.
  • An embodiment with a particularly simple structure and trouble-free mode of operation can be achieved in a further development of the inventive idea by the two capes Combs are slidably mounted in their longitudinal direction in a common slide which is movable transversely to the capes from and to the needle bed and is supported by a guide which extends over the length of the needle bed and which is pivotable up and down about a pivot axis parallel to the needle bed.
  • each shoulder finger consists of two finger halves lying vertically next to one another and punched out of sheet metal material and which are releasably clamped between the strips forming the comb body with their rear ends facing away from the needle bed.
  • FA and FP are the two needle beds of a two-contour flat knitting machine which are inclined towards each other in a roof shape and with the associated latch needles AT1 and AT2.
  • this flat knitting machine reductions and increases in a manner known per se can only be achieved by moving the needle stitches of one e.g. of the rear needle bed FP, regardless of whether the knitted fabric is produced with the aid of a single needle bed or with the aid of the two needle beds FA, FP.
  • the stitch transfer device according to the invention used in the exemplary embodiment shown as a reducing and increasing device is arranged, for example, over the front needle bed FA and interacts with the opposite, ie rear, needle bed FP.
  • This guide 1 consists of an upper guide bar 101 and attached lower guide brackets 201 and is pivotally mounted on a machine frame 3 up and down about a pivot axis 2 parallel to the needle bed FA or FP.
  • the guide 1 is supported on an underlying stop bar 4.
  • the stop bar 4 is pivotally mounted on the machine frame 3 about an axis 104 parallel to the pivot axis 2 of the guide 1 and is firmly connected at one end to a lever arm 5 which cooperates with a cam disk 6 fastened on the shaft 7.
  • 1, 4 and 5 shown in full lines, swiveled, approximately horizontal angular position of the stop bar 4, the guide 1 supported thereon also assumes its swiveled position.
  • the stop bar 4 is pivoted upward about the pivot axis 104 with the aid of the cam 6 and the lever arm 5, it also lifts the guide 1 into its position pivoted upward about the pivot axis 2, as shown in broken lines in FIG. 4.
  • a slide 8 is mounted in the guide 1, which extends parallel to the needle bed FP along its length and can be moved transversely to its longitudinal direction from and to the needle bed FP.
  • the carriage 8 is mounted suspended on the underside of the guide bar 101 with the aid of a transverse dovetail guide or the like.
  • a rocker arm 18 is pivotally mounted in the machine frame about an axis 19 parallel to the needle bed FP, as is shown in particular in FIG. 2.
  • One end of this rocker arm 18 interacts with a cam disk 20 fastened on the shaft 7, while a driver pin 17, which projects laterally from the relevant end of the slide 8, engages in the other fork-shaped end of the rocker arm 18.
  • neck combs 9 and 9 'are mounted for longitudinal displacement.
  • each individual neck comb 9 or 9 takes place with the aid of a drum curve 23, in which one end of a rocker arm 21 engages.
  • the same drive arrangement is of course also provided for the other neck comb 9 'on the right in FIG. 2, but is not shown in the drawing.
  • the articulated connection between the rocker arm 21 and the associated neck comb 9 is required in order to enable the transverse displacement of the neck combs 9, 9 'directed to and from the needle bed FP together with the carriage 8.
  • the intermediate joint piece 24 can be replaced by any other joint connection.
  • each needle AT2 of the needle bed FP or every second or third needle AT2 of the needle bed FP can be assigned a transfer finger P of the relevant transfer comb 9 or 9 '.
  • the neck fingers P of the two neck combs 9 and 9 ' can only be used in certain areas e.g. be provided at the end regions of the needle bed FP and be assigned to each individual needle AT2 or every second or third needle AT2 in these regions.
  • each neck comb 9 and 9 ' consists of two superimposed comb strips 11 and 12, which are firmly connected to one another by means of screws 13, between which the individual ones Neck fingers P are releasably clamped with their rear ends, ie ends remote from the needle bed FP.
  • the two finger halves P1 and P2 each have a V-shaped notch'10 in the upper edge of their rear ends.
  • a continuous, V-shaped groove 14 is provided in the underside of the overlying comb strip 12.
  • a wire 15 made of relatively easily deformable metal, such as copper or plastic with similar strength or elastic properties.
  • the rear ends of the shoulder fingers P or the finger halves P1, P2 are pressed between the two comb strips 11 and 12 with the interposition of this copper wire 15 or the like and thereby clamped.
  • One finger half P1 of each shoulder finger P is made of thicker sheet metal than the other finger half P2 and has a side indentation 16 in its front, tapered end facing the needle bed FP, into which the front, also tapered and laterally inward bent end of the thinner finger half P2 engages, as shown in particular in Fig. 3.
  • the bent front end of the thinner and therefore also more elastically deformable finger half P2 can be resilient laterally swung out of the recess 16 of the other, stronger and therefore also more rigid finger half P1 and thus moved away from the latter so far that a needle AT2 can be passed between the temporarily separated front ends of the two finger halves P1 and P2.
  • the needles AT2 lying in the needle bed FP are raised into the transfer position shown in FIG.
  • the needles AT1 of the needle bed FA are all lowered, i.e. withdrawn into the needle bed FA.
  • the carriage 8 with the two neck combs 9 and 9 ' is retracted in the pivoted guide 1 from the needle bed FP.
  • there is one transfer finger P of the assigned transfer comb 9 or 9 '. This initial position of the stitch-transfer device is shown in FIG. 1.
  • the guide 1 is then pivoted together with the carriage 8 and the two neck combs 9, 9 ', so that the neck fingers P engage again in the upper ends of the needle beds FA, FB.
  • both needle beds can each have a stitch cape according to the invention direction can be assigned.
  • electromechanical, pneumatic or hydraulic drive means can also be provided for the drive.
  • the inventive mesh wrap not only needs to be used as a reducing and / or increasing device, but can also be used for other purposes, for example for the manufacture of openwork knitted fabrics.
