Definitions

  • the most common way of producing a twine is that in a first stage of work using suitable spinning units, e.g. Rotor spinning or friction spinning devices are made from dissolved fiber material or ring spinning devices, which are spun in a subsequent work step by means of twisting devices, e.g. Double wire twisting devices to be processed into a twine.
  • suitable spinning units e.g. Rotor spinning or friction spinning devices are made from dissolved fiber material or ring spinning devices, which are spun in a subsequent work step by means of twisting devices, e.g. Double wire twisting devices to be processed into a twine.
  • twisting devices e.g. Double wire twisting devices to be processed into a twine.
  • independent spinning machines acting on the one hand and threading machines on the other hand are required, which is complex both in terms of machine and in terms of the workflow.
  • the invention is concerned in advance with the idea of creating a method for producing a thread in an integrated spinning-twisting process, which works on the double-wire principle.
  • thread balloon An essential element in the double wire twisting process is the thread balloon, in which the thread forms an envelope around the stationary bobbin of the thread spindle, which was previously regarded as impenetrable in order to allow material flows, e.g. also fiber material to feed into the space enclosed by the thread balloon.
  • DE-OS 1 785 366 dating from 1972, deals with a spinning process, which at this time is still referred to as "element spinning", in which fiber material is arranged into a fiber band, which is brought into the form of a rotating balloon, in which is given to the sliver at least two turns per revolution of the balloon and the resulting yarn is drawn off.
  • the device for carrying out this known spinning process has a spinning chamber which is arranged on a spindle and into which the fiber material is introduced through a fiber inlet tube which runs coaxially to the spindle axis and a channel which runs radially through the spindle rotor. Inside the spinning chamber there is a collecting ring for the fiber material, which is formed into a fuse there.
  • the stretched fiber sliver is guided through a channel lying in the spindle axis, in which it receives a first rotation and from which it emerges in the radial direction and enters a rotating balloon surrounding the spinning chamber, in which it receives the second rotation.
  • the thread drawn off from the spinning rotor is returned to the common axis of the spinning rotor and the double-wire rotor by a draw-off channel arranged in the double-wire rotor and running in an arc around the outside of the spinning rotor, and is discharged upwards through the drive device of the double-wire rotor.
  • a second turn is applied to the thread.
  • the fiber material is fed to the spinning rotor through a feed channel in the double-wire rotor, the receiving opening of which is symmetrical and the discharge opening of which is eccentric to the axis of the double-wire rotor.
  • the invention has for its object to provide a method for producing a thread from at least two yarn components, in which only twisted fiber material is fed to the twisting spindle and the finished twisted thread is withdrawn from the spindle.
  • the basic idea of the invention in particular in terms of the design of the device, is to use the fiber material introduced into the twisting spindle through the rotating thread balloon directly for the production of a twist from at least two spun threads and this fiber material so that it does not disturb the balloon on the one hand and on the other hand there is enough space to accommodate several spinning units within the space defined by the thread balloon, to which the fiber material is fed in separate streams, while the spinning threads drawn off by the spinning devices together through the hollow spindle axis and Thread balloon are guided.
  • the space previously occupied by the necessary supply spools is available to the spinning units and their drive mechanism.
  • the spinning and twisting technology process in the open-end spinning-twisting system according to the invention is as follows:
  • Dissolved fiber material is preferably fed through the thread balloon to the interior of the spindle just above or in the preferably upper region of a thread guide element that rotates with the thread balloon - balloon limiter or thread guide tube.
  • the thread is preferably guided through a thread guide element attached to the rotating thread guide element.
  • Each fiber stream supplies a spinning unit, for example a spinning rotor.
  • the spinning rotors are driven by an electric motor in the opposite direction to the direction of rotation of the double-twisted spindle.
  • a spinning thread is pulled up from each spinning rotor and fed to the spindle center, that is to say the hollow axis of the double-wire twisting spindle.
  • the trade association is created, which is directly followed by the first twisting zone of the double-wire twisting spindle connects.
  • the thread is then conveyed radially outwards through the usual thread guide channel and deflected upwards along the thread guide element which also rotates with the spindle rotor, whereby it is guided in the area of the fiber feed or fiber feed through the thread guide element which also rotates before it is in the extension of the hollow spindle axis Centering point, for example a balloon thread guide eyelet, passes through.
  • a positively driven take-off unit which is fixed to the frame and which is followed by a conventional thread winding unit. Between the take-off unit and the take-up unit, a conventional thread length compensation unit is arranged, which has a certain thread storage function.
  • the feeding or feeding of the dissolved fiber material to or into the spinning units is preferably carried out by means of negative pressure, which is built up in the area of the spinning units by a suction pipe running in the area of the spindle axis, which is connected at its outer end to a suction source, while to the Connect the inner end of this suction tube air channels, which are guided so that they are able to build up a negative pressure gradient in the direction of the fiber feed, causing the fiber feed to the spinning units, in the fiber material feed tubes of the spinning units.
  • FIG. 1 shows a schematic representation of the process sequence of the open-end spinning-twisting method according to the invention within a space of a double-wire twisting spindle enclosed by a thread balloon.
  • FIG. 2 shows, partly in section, a perspective view of a double-wire twisting spindle with an upstream fiber-dissolving unit and a downstream thread winding unit.
  • FIG. 3 shows a sectional view of a double-wire twisting spindle with integrated spinning units in the form of spinning rotors.
  • the schematic representation according to FIG. 1 shows two rotor spinning devices R1 and R2 which are arranged directly adjacent to one another and driven by a motor M, and which have fiber material dissolved in the direction of arrows f1 and f2 through fiber material supply tubes 3 and 4 and directly in the spinning rotors 1 and 2 outgoing fiber material feed pipes 5 and 6 are supplied.
  • the spun threads F1 and F2 produced within the spinning rotors 1 and 2 according to the usual open-end process are drawn upwards from the spinning rotors 1 and 2 open at the top and brought together at a union point P, from where they form a twine in accordance with the double-wire principle F3 can be combined by axially along the axial wire in the usual way through the double-wire twisting spindle shown schematically in FIG.
  • the spindle axis is withdrawn and, after exiting the radial thread storage channel, forming a thread balloon up to the centering point defined in the extension of the spindle hollow axis, defined by the two roller bodies a and b , and from there it is carried on in the usual way to a thread winding unit.
  • the spinning rotors 1 and 2 rotate in the same direction in one direction of rotation, while the spindle rotor, not shown, of the double-wire twisting spindle in the direction of the arrow f5 opposite to the two spinning rotors circulates.

  • the two spinning threads drawn off from the spinning rotors 1 and 2 are combined with one another in the region of the upper inlet opening 11a of the hollow spindle axis 11, they pass through the hollow spindle axis in the direction of the arrow f6 downward, and are then drawn off radially outward in the direction of the arrow f7 before they are drawn off essentially upwards in the direction of arrow f8 along the inner surface of the balloon limiter 7 and are guided to a delivery mechanism 16, 17 through a thread outlet opening located coaxially to the spindle hollow axis on the upper side of the outer housing 10.
