Definitions

  • the invention relates to a device for forming a leno selvedge, in particular in the case of weaving machines without protection, a stationary guide frame being provided, through which a warp thread holder and a thread guiding device for the leno thread are guided.
  • a device for forming a leno selvedge wherein mutually moving heald frames are provided, and wherein a plurality of warp thread holders, preferably held by means of a frame, are arranged on one heald frame for guiding the warp threads, and a thread guide device is arranged on the other heald frame, which device is arranged by the Frame is guided.
  • the thread guide device and the frame with the warp thread holders arranged thereon are moved relative to one another.
  • the mass of the thread guide device is negligibly small compared to the frame with the warp thread holders, so that the forces for deflection can be correspondingly small even at higher stroke rates.
  • the mass of the frame with the warp thread holders is extremely large; this requires a large drive power and ultimately also large restoring forces, especially at high stroke rates.
  • Patent Specification 1 369 686 in which a frame is provided which has a plate in which the warp thread holder on the one hand and the thread guide frame for the leno threads on the other hand are guided.
  • the warp thread holder is driven with the aid of an eccentric drive, and the thread guide device for the leno thread is driven with the aid of an eccentric device.
  • the invention is therefore based on the object of providing a device for forming a leno edge which manages with small moving masses and in which the frictional forces are also extremely low.
  • the guide frame for the warp thread holder and for the thread guiding device consists of two frame parts, each consisting of two stationary U-shaped opposing frame rails and the thread guiding device and the warp thread holder at one end each with a heald frame or with harness cords are connected to a jacquard machine and that the thread guide device and the warp thread holder are each held at their other end by springs which bring about the return movement.
  • the construction of the device for forming a leno edge according to the invention means that it is no longer necessary, as in the prior art, to move the entire guide frame including the warp thread holder, but only the warp thread holder itself, that is to say in principle only the needles.
  • the energy required for resetting and accelerating can also be considerably reduced.
  • the result of this is that far higher numbers of shots and thus strokes per minute can be realized than before.
  • the springs that cause the return movement of the warp thread holder can be dimensioned smaller.
  • This device can be used not only in connection with a loom equipped with heald frames, but also in a loom in which a jacquard machine or an eccentric device is provided.
  • the warp thread holder has a guide part which is guided in the guide frame, the guide part its length corresponds approximately to the sum of the length of the opposite needles of the warp thread holder.
  • the guide part in the guide frame is made by a friction reducing bearing, e.g. passed through two needle bearing blocks. This results in a reduction in the frictional heat generated, so that it is ensured that the guide part does not get stuck in the guide frame even at a high number of strokes.
  • stroke limits for the warp thread holder are provided in the guide frame.
  • the warp thread holder has eyelets at both ends of the guide part for guiding the warp threads.
  • Separate guides in the frame rails are therefore no longer required in this type of device for forming a leno edge. This further reduces the risk of thread breaks, since the warp thread is no longer deflected as often.
  • the device for forming a leno selvedge consists of two mutually moving heald frames 1 and 2, the thread guide device 3 being fastened to the heald frame 1 and the warp thread holder, denoted overall by 4, to the heald frame 2.
  • the thread guide device 3 and the warp thread holder 4 are guided in the fixed guide frame designated 5.
  • the guide frame 5 consists of two frame parts 6 and 7, which are each formed from two oppositely arranged U-shaped rails 6a and 6b or 7a and 7b (FIG. 2), the thread guide element 3 in the rails 6a, 6b of the frame part 6 is performed.
  • the warp thread holder 4 which carries the needles 10 and 11, has a guide part 8 which is guided in the two oppositely arranged U-shaped rails 7a and 7b of the frame part 7.
  • the length of the guide part corresponds approximately to the sum of the length of the opposing needles.
  • needle bearing strips which are designated by 9a and 9b, are arranged in the end faces of the rails.
  • the warp thread holder 4 also has the eyelets 12 and 13, which serve to guide the warp threads to the eyelets 10a, 11a of the needles 10, 11 (warp thread not shown).
  • the mutually moving heald frames 1 and 2 move the thread guiding device 3 and the warp thread holder, generally designated 4, relative to one another in the fixed guide frame 5.
  • the return movement, both of the thread guiding device and of the warp thread holder, takes place through the springs 14 and 15 attached to it.
  • stroke limits 16a, 16b are provided, which preferably consist of an elastic material, for example hard rubber.
