Definitions

  • the invention relates to a thread guide, in particular for a flat knitting machine, with a thread guide arm.
  • Thread guides for flat knitting machines with a thread guide arm are known from DE-C 31 29 512 and DE-C 33 10 723. Since several thread guide arms or the nuts attached to them at the lower end have to be moved past one another as space-saving as possible, the thread guide arms are designed to be elastically resilient so that they cannot get caught in one another when driving past other thread guide arms.
  • the thread guide arms are integrally formed and attached to the thread guide box.
  • the invention is therefore based on the object of providing a thread guide with a thread guide arm which has a simple structure, is elastic at defined points and the arms of which have a predetermined elasticity regardless of the shape or orientation.
  • the object is achieved in a thread guide with a thread guide arm in that the thread guide arm has an upper and a lower arm part, which are connected to one another via an elastic connecting element.
  • the thread guide arm according to the invention is formed in two parts.
  • the two parts are connected to one another via an elastic connecting element, in order to ensure the elastic suspension required for the thread guide arms to dodge one another.
  • the elastic connecting element can be selected depending on the machine conditions or the wishes of the user, so that the optimal elasticity can only be selected by choosing the material or the dimensions of the connecting element.
  • one-piece thread guide arms in which the elasticity is determined by the material of the thread guide arm and the elasticity cannot be defined in a defined manner over the entire free length of the thread guide arm and thus uncontrolled reverberation of the thread guide arms is possible with the thread guide arm according to the invention Avoid swinging or uncontrolled springing of the thread guide arm. This increases the operational safety of the machine and reduces downtimes.
  • the thread guide arm according to the invention is also very inexpensive to manufacture.
  • the elastic connecting element is an elastic steel plate, which is chosen in terms of its strength, dimensions and / or choice of material in such a way that optimum elasticity or suspension results without reverberation.
  • the elastic connecting element is preferably fastened to both the upper and the lower arm part, again by the distance of the lower and the upper arm part to each other the elasticity of the elastic connecting element is adjustable or selectable.
  • a rigid holding plate is provided on a flat side of the upper and lower arm part, which is fixedly attached to the upper arm part, for example with screws.
  • the holding plate has at least one pin bearing in a complementary hole in the lower arm part.
  • the elastic connecting element is provided which is fixedly attached to the upper arm part. The upper end of the lower arm part is thus held in a sandwich-like manner between the holding plate and the elastic connecting element without a rigid connection to the holding plate, while the lower end of the upper arm part is firmly connected to both the rigid holding plate and the elastic connecting element.
  • the deflection is preferably only to one side, preferably to the outside, so that it is only necessary to provide a deflection or elasticity of the lower arm part on one side, namely on the side facing away from the rigid holding plate.
  • the pin projecting into a complementary hole of the lower arm part should preferably be so long that even with the greatest elastic deflection of the lower arm part this pin does not emerge from the complementary hole of the lower arm part.
  • a hole is provided in the elastic connecting element for the pin and the pin is designed so long that it also with elastic deflection of the elastic connecting element and thus the lower one Arm part still protrudes further into the hole in the lower arm part complementary to the pin.
  • the rigid holding plate has lateral guide legs, so that the lower end of the upper arm part and / or the upper end of the lower arm part lies in an inner surface of the rigid holding plate delimited by the lateral guide legs.
  • the lateral guide legs preferably protrude so far from the inner surface against which the lower end of the upper arm part and the upper end of the lower arm part rests that the guide legs also give lateral support to the elastic connecting element on the other side of the arm parts.
  • the rigid holding plate or its inner surface is preferably formed by milling.
  • the dimensions of the inner surface essentially correspond to the dimensions of the lower end of the upper arm part and the upper end of the lower arm part in any case insofar as these ends lie on the inner surface of the rigid holding plate.
  • fasteners for fastening the elastic connecting element and / or the rigid holding plate to the upper arm part anyway, it is provided according to an advantageous embodiment of the invention to use these fasteners at the same time for attaching a thread guide part, for example, eyelets for deflecting or guiding them threads to be fed to the nut.
  • a thread guide arm 1 is fastened to a thread guide box 3 with a screw 2.
  • the thread guide arm 1 consists of an upper arm part 4 and a lower arm part 5.
  • the upper end 10 of the lower arm part 5 is arranged in a sandwich-like manner between the parts of the rigid holding plate 7 and the elastic connecting element 8 projecting downwards and projecting over the lower end 6 of the upper arm part 4.
  • a pin 11 protruding from the rigid holding plate 7 protrudes toward the lower arm part 5 and protrudes through a complementary hole 12 in the upper end 10 of the lower arm part 5 and into a corresponding hole 13 in the elastic connecting element 8 provided on the other side.
  • the lower arm part 5 is thus held between the rigid holding plate 7 and the elastic connecting element 8 by the pin 11.
  • the rigid holding plate 7 has lateral guide legs 14, 15 which protrude on the sides of the rigid holding plate 7, so that there is a delimited inner surface for the lower end 6 of the upper arm part 4 and the upper end 10 of the lower arm part 5 results.
  • the elastic connecting element 8 is rigidly connected to the upper arm part 4 via the two fastening elements 9, lateral guidance or mounting of the elastic connecting element 8 is not necessary per se.
  • the lateral guide legs 14, 15 also contribute to the guidance and lateral fixation of the elastic connecting element 8 if the lateral guide legs 14, 15 protrude sufficiently from the inner surface.
  • the lower end 6 of the upper arm part 4 and the upper end 10 of the lower arm part 5 are placed in the inner surface of the rigid holding plate 7 delimited by the lateral guide legs 14, 15, the pin 11 being inserted into the complementary hole of the lower arm part 5 protrudes.
  • the elastic connecting element 8 is placed.
  • the rigid holding plate 7 and the elastic connecting element 8 are then simultaneously rigidly fixed on the upper arm part 4 with fastening elements 9, for example with screws or bolts. Due to the elasticity of the connecting element 8, it is now possible for the lower arm part 5 to be elastically deflected away from the rigid holding plate 7.
  • the attachment of the elastic connecting element and / or the rigid holding plate 7 to the arm parts 4, 5 is not limited to the exemplary embodiment shown.
  • the rigid attachment can also be carried out on the lower arm part 5 and the sandwich attachment on the upper arm part 4.
