Definitions

  • the invention relates to a yarn guide for a flat knitting machine which is along a yarn guide rail by a bolt arranged on the machine slide yarn guide driver longitudinally displaceable and the one by the bolt of the yarn guide driver from its working position in at least one out-of-service position and back movable yarn guide arm having a nut.
  • Such a yarn guide is for example from the DE 42 22 934 or from the DE 43 00 027 known.
  • These yarn guides are by electromagnetically acted yarn guide-driver, as for example from the DE 39 22 513 C2 are known, taken during the knitting process and parked at any position of the carriage travel.
  • the thread guide arm In the rest position of the thread guide, the thread guide arm can execute a defined movement with the nut against the previous thread guide movement, ie the thread guide arm with the nut is brought from a working position into an off-mode position. In the out-of-action position, the nut is raised relative to the working position and offset horizontally. Instead of the superimposition of two linear movements, the nut can also be brought into its out-of-action position by pivoting the thread guide arm.
  • the known thread guides have despite constructive differences following commonality:
  • the yarn guide arm with the nutlets can only during movement of the machine carriage opposite to the direction in which he was brought from the working position into the non-action position, be moved back to its working position from the addition of activity Position ,
  • the known yarn guides are suitable for the production of intarsia knits, in which the yarn guide only has to be activated again after reversing the carriage direction, but not z.
  • the thread guide must be activated in the same carriage direction in which he was disabled.
  • EP 0 872 587 discloses a yarn guide device, wherein the yarn guide is taken by a yarn guide driver with the carriage. After switching off the thread guide, the nut is lifted by spring force. The required horizontal movement of the nut to reach its non-operative position is effected by the displacement of the entire yarn guide by an additional drive device.
  • the additional drive device consists of a longitudinally movable on the yarn guide rail steel strip to which the yarn guide is magnetically fastened. The steel strip is connected at one end to a rack on which an electric motor attacks.
  • this thread guide allows the adjustment of the nutshell in its working position in a carriage movement in the same direction in which the adjustment is made in the off-mode position, but the possibility of this adjustment is due to a high design effort.

  • the thread guide can thus be operated only by specially designed for him thread guide driver.
  • the present invention is based on the object, a yarn guide of the type mentioned in such a way that it can be brought in a structurally simple manner in the same carriage direction from its non-operative position in working position in which he was brought from its working position to the off-mode position, and thereby remains movable by standard thread guide driver.
  • the resetting of the yarn guide arm is easy in its working position in the same carriage direction as in its movement into the off-mode position possible with the thread guide driver. Additional drive devices for the yarn guide arm or even for the entire yarn guide can therefore be omitted here.
  • the yarn guide arm as known in marquetry yarn guides, are brought into two arranged in mirror image to the working position off-work positions.
  • the Nüsschen arranged on the yarn guide arm is moved back horizontally relative to the carriage direction, so that in Intarsia crocheted at the beginning of a new color field, the Nüsschen the use of a new Thread guide not hindered.
  • the nut With two mirror-image off-mode positions, the nut can thus be moved back in both carriage directions in order to make way for the new thread guide.
  • the yarn guide arm can be brought not only in one of the direction of movement of the machine carriage trailing, but also in a leading out of action position. In fact, in some applications, it may be necessary to place the yarn guide arm in an off-axis position horizontally offset forward in the carriage direction.
  • the yarn guide arm can be brought in principle by two different movements in its off-mode position. Thus, once the thread guide arm can be brought by a vertical movement and a horizontal movement in the machine longitudinal direction from the working position in the at least one out-of-action position. In the alternative embodiment of the yarn guide arm can be brought by a pivoting movement from its working position in the at least one out-of-action position.
  • the yarn guide has at least one adjusting element for the yarn guide arm on which a pin of the yarn guide driver can engage.
  • the yarn guide according to the invention can thus be adjusted by standard yarn guide drivers who take the thread guide by bolts.
