Definitions

  • the invention relates to a intermingling nozzle for threads or yarns, with a plurality of plates arranged side by side in a reed-like manner, in which parallel thread ducts and cross-flow openings into the thread ducts, to which a blowing medium can be applied, are formed, with the axes of the thread ducts in one of the plates vertical plane.
  • a swirling nozzle of this type is known from DE-A-3019302.
  • the plates form a block-shaped arrangement in which the thread channels are formed by leaving a straight gap of rectangular cross-section between an upper and a separate lower plate part.
  • the threads must be threaded individually; inserting or adding threads is not possible.
  • the division, i.e. the distance between the thread channels perpendicular to the thread running direction is comparatively large.
  • a swirling nozzle which consists of two blocks abutting one another in a horizontal plane.
  • the blocks are provided with grooves serving as thread channels on the abutting contact surfaces.
  • the threads can then be inserted into the thread channels by lifting off the upper block, for example by swiveling the upper block upwards Free access to the thread channels is impeded even when open.
  • a swirl nozzle in which a tubular body containing the thread channel is rotatably mounted about its longitudinal axis in cylindrical bores, namely between an open position in which the thread channel is freely accessible and a closed position in the thread channel is closed to the outside.
  • the invention has for its object to develop a swirling nozzle of the type specified in such a way that the threads or yarns can be inserted during the run despite a low air consumption and the narrowest possible division of the thread channels.
  • a swirling nozzle with the features specified at the outset in that two adjacent plates each consist of a fixed thread channel plate and a movable closing plate, of which the thread channel plate provides a groove serving as a thread channel on its side adjacent to the closing plate and the closing plate can be moved parallel to the plate planes between an open position releasing the thread channel and a closing position covering the thread channel.
  • the "closed position” represents the working position of the swirling nozzle.
  • the thread channels are in the open position the swirl nozzle freely accessible from one side.
  • the threads or yarns can therefore be inserted during the run, for example by moving the entire intermingling nozzle in the direction of the threads. Since the thread channels are closed in the closed position, the consumption of blowing medium, in particular air, can be kept low.
  • the division of the swirling nozzle depends solely on the thickness of the plates, so that the division can be chosen to be comparatively small.
  • the division of the intermingling nozzle can be kept very narrow.
  • the manufacturing outlay remains comparatively low. Nevertheless, the swirling nozzle designed according to the invention can produce a high swirling performance.
  • the intermingling nozzle designed according to the invention is particularly suitable for intermingling sheets of coarse-titer yarns such as are used for reinforcing fabrics or tires (tire cord).
  • the swirling nozzle shown in the figures has a carrier 10.
  • a group of flat thread channel plates 12 is fixedly attached to the carrier 10, which are arranged side by side and alternately to flat closing plates 14.
  • the closing plates 14 are rotatably attached by a wedge 20 on a shaft 18 which is rotatably mounted in bores in the thread channel plates 12.
  • the shaft 18 is provided at one end with a contact head 21 and at its other end with a thread 22 onto which a nut 23 is screwed.
  • the shaft 18 and the nut 23 hold the thread channel plates 12 and the closing plates 14 in contact with one another under a given pretension with the aid of a plate spring 24, but without hindering movement of the closing plates 14 in planes parallel to the thread channel plates 12.
  • At least one, and preferably two, of the locking plates 14 are provided with a toothed segment 26 which is in engagement with a toothed wheel 28 driven by a compressed air motor (not shown).
  • the closing plates 14 are rotatable about the longitudinal axis of the shaft 18.
  • the rotational movement of the closing plates 14 is limited to 90 °, specifically through recesses 30, which are formed in the thread channel plates 12 and extend through 90 ° and into which the wedge 20 engages. In this way, the locking plates 14 between a closed position and a 90 ° offset to this, in the figures 1 and 2 shown open position adjustable.
  • the thread channel plates 12 are each provided on their sides abutting the closing plates 14 with a straight, continuous groove 32 of rectangular cross section, which serves as a thread channel. From each thread channel groove 32 there is a straight groove 34, 36 at right angles thereto and on opposite sides, which acts as a blowing channel for blowing in a swirling medium, in particular air, is used in the thread channel.
  • the blow channel grooves 34 and 36 formed in the sides of the thread channel plates 12 each open into a bore 38 or 40 running perpendicularly through the thread channel plate 12.
  • Corresponding bores 44 and 46 are formed in the closing plates 14, which in the closed position of the closing plates 14 are aligned with the bores 38 and 40 of the thread channel plates 12 and thus form feed channels 48 and 50 for feeding the blowing medium.
  • the supply channels 48 and 50 are supplied with the blowing medium from the external thread channel plates 12 via a device (not shown) which automatically interrupts the supply of the blowing medium when the swirl nozzle is opened.
  • the closing plates 14 are provided with a rectilinear outer edge 51, which in the open position of the closing plates 14 run parallel to the thread channel grooves 32.
  • the arrangement and design of the thread channel plates 12 and closing plates 14 is such that the closing plates 12 in the open position release the thread channel grooves 32 completely in the thread running direction, but only partially perpendicular to the thread running direction, so that the threads F are inserted into the thread channels can be, but have a certain hold in them.
  • the outer edges 51 of the closing plates 14 are provided with roof-shaped bevels 52 which are inclined towards the thread channels in the open position of the closing plates in order to facilitate the insertion of the threads F.
  • the adjacent sides of the thread channel plates 12 and the closing plates 14 are honed or lapped to achieve a high surface quality, so that a perfect mutual contact of the thread channel and closing plates is guaranteed.
  • the entire intermingling nozzle is moved out of the area of the threads with the aid of the displaceable carrier 10.
  • the locking plates 14 are in their open position (shown in the figures).
  • the swirling nozzle is moved in the direction of the running threads F (upwards in FIGS. 1 and 2).
  • the threads F slide over the bevels 52 in this case the thread channel grooves 32 without their running having to be interrupted, whereupon the closing plates 14 are pivoted via the pinion 26, 28 into their closed position, in which they close the thread channels and the blowing channels with the holes 38, 44 and 40, respectively , 46 formed feed channels 48, 50.
  • the supply of the blowing medium preferably air
  • the blowing medium is initiated automatically in order to swirl the threads F running through the thread channels.
  • thread channel and closing plates can also be found in larger groups of e.g. 20 to 25 plates can be combined.
  • the intermingling nozzle described can be used in particular when stretching sheets of coarse-titer yarns, such as are used for reinforcing fabrics or tires.
  • These are yarns with a yarn titer of approximately 500 to 2500 dtex, mostly between 1000 and 1700 dtex, with a single titer of 3 to 15 dtex, preferably from 5 to 8 dtex.
  • the drawing of these yarns and thus the intermingling takes place mostly at speeds of 100 to 500 m / min on so-called belt roads.
  • the yarn tension in the intermingling zone is usually between 0.01 and 0.1 cN / dtex.
  • the interlacing nozzle shown allows a very narrow division of the thread channels, for example from 4 to 6 mm, but also up to 2 mm. This allows tight yarn guidance and thus good utilization of the godets and heating elements of the drawing systems.
  • a tire cord with a titer of 1440 dtex, a running speed of 220 m / min, a pitch of 1 thread / 4.8 mm, a thread tension of 40 cN / 1440 dtex and an air throughput of 3.5 resulted Nm3 / h a needle test value (Rothschild Entanglement Tester R2040) from 120 to 200 mm.
