  • the Fadenrisonarm has a stop surface which has a directed away from a free end of the Faden concernedarms angle to the longitudinal axis of the Faden concernedarms ⁇ 90 °.
  • the thread eye is automatically or accidentally removed in the direction of a needle bed from the Fadenhostarm.
  • the thread eyelet is securely held in the direction of the needle bed on the thread guide arm.
  • the change of a thread eyelet is particularly simple when the thread guide arm has two expandable legs at its free end, between which the thread eyelet is arranged. By widening the legs creates an extended slot into which the thread eye can be inserted. In particular, the legs can be widened by means of the tool. In this connection, the bevel provided on the thread guide arm can serve to cause the legs to widen by moving the thread eye along the slope.
  • a tool engagement on Fadenfadenarm and a tool engagement is arranged on the thread eyelet.
  • the tool engagement on the thread guide arm and the tool engagement on the thread eye preferably lie on a longitudinal axis of the thread guide arm.
  • two tool engagements are provided on the yarn guide arm, in particular on each one leg of the yarn guide arm.
  • the legs can be widened by means of the tool which acts on the tool engagement, so that a thread eyelet can be inserted or removed.
  • the tool engagements may allow power transmission in at least one direction.
  • the direction of the power transmission can be dependent on the tool used.
  • the tool engagements may include a guide portion for the tool. This can prevent the tool from slipping off.
  • the tool engagements may be formed like a blind hole or as through holes.
  • the scope of the invention also includes a flat knitting machine with a yarn guide according to the invention.
  • the Fig. 1a shows a section 100 of a flat knitting machine not shown with yarn guide units 1, which are mounted on a plurality of yarn guide rails 10 in the longitudinal direction of the yarn guide rails 10 slidably.
  • the thread guide units 1 on self-powered thread guide which are driven in particular motor-driven without the influence of the carriage, not shown here.
  • the invention can also be used with thread guides, soft z. B. be moved by the carriage by means of corresponding driving devices.
  • the Fig. 1b shows an enlarged view of two of the yarn guide units 1 of Fig. 1a , On a yarn guide box 2, which is attached to a yarn guide rail 10, a yarn guide arm 3 is arranged, which extends from the yarn guide box 2 down. In the following, only the Fadenizatarm 3 will be further described.
  • the Faden necessarilyarm 3 has a rod 4, which is guided vertically movable, so that up and down movements at a free end of the Faden concernedarms 3 in the region of a thread eye 5 are possible.
  • the rod 4 is fork-shaped at its free end with legs 6 a, 6 b formed.
  • the elastically deformable legs 6a, 6b close the thread eyelet 5 between them.
  • the up-down movement is not mandatory. If no up-down movement is provided, the thread eye 5 is in the arm third
  • the Fig. 2a shows the insertion of a thread eye 5 in a mounting position on Faden ownedarm 3.
  • a first tool engagement 7a is shown on the rod 4 of the Faden concernedarms 3.
  • Another tool engagement 7b is arranged on the thread eye 5.
  • a tool in the form of a circlip pliers 30 can engage in the tool engagements 7a, 7b by means of its lugs 31, 32, which are arranged on legs 33, 34 of the circlip pliers 30.
  • the thread eye 5 is inserted into the recess 6 between the legs 6a, 6b.
