Definitions

  • the invention relates to a device for melt spinning, drawing and winding a plurality of multifilament yarns according to the preamble of claim 1.
  • the multifilament yarns are spun after melting and wetted to merge, on the one hand, the plurality of fine filaments within the yarn and, on the other hand, to produce an antistatic state Filament bond of the thread safely over guide elements and godets to lead. Therefore, it is customary to perform such wetting of the filaments immediately after a first cooling of the filament strands.
  • the wetting liquid introduced into the thread composite also has the disadvantage that, in particular in the case of heat treatments, the wetting liquid also has to be heated or vaporized, depending on the type and composition, in order to heat the thread material to specific treatment temperatures. In the prior art, therefore, different methods and apparatus are known to be able to supply a wetting liquid to the threads.
  • a device in which the preparation device is formed by two separate preparation stations In a first preparation station, which is arranged upstream of a drawing device, a pre-preparation of the thread takes place. In this case, a preparation quantity of a wetting liquid, which is adapted to the subsequent heat treatment, is fed to the yarn. After the heat treatment and the stretching takes place in a second preparation station, a post-preparation to the required for the further treatment amount of a wetting liquid in the Thread to bring.
  • Each of the preparation stations thus supplies a fixed predetermined subset of the wetting liquid to the threads.
  • the preparation device is formed by a preparation station, which is assigned directly to the cooling device, such as from DE 103 09 966 A1 is known.
  • the preparation station of the cooling device is assigned and formed controllable for applying a wetting liquid.
  • the preparation station can be operated between a process speed for producing the threads and an application state at the start of the process. In that regard, a predetermined predetermined amount of wetting liquid is supplied to the threads in each operating state.
  • the threads are already wound into coils, which are treated as yarn waste.
  • bobbin changes are therefore carried out in order to avoid thread mixing in the bobbins.
  • operating conditions are to be taken into account in which the threads are preferably severed in front of the drawing device due to yarn breakages and continuously fed to a waste via a stationary suction device.
  • the object of the invention to provide a device of the generic type, with which a flexible wetting of the threads in dependence on the respective requirements and operating conditions is possible.
  • the invention is characterized in that at least one of the preparation stations can be used to one on the respective Operating condition adapted wetting of the threads to get. In this case, alternatively, only the delivered amount of wetting liquid can be changed or a complete shutdown and connection of the preparation station can be realized. Whereby, in the switched-on state, a change of the wetting amount to be dispensed is also possible.
  • at least one of the preparation stations for setting a thread wetting is controllable and / or switchable.
  • the first preparation station is formed with a movable wetting agent, so that the wetting agent can be guided either into an operating position with thread contact and into a rest position without thread contact. For threading and applying the threads they are guided with thread contact to the wetting agent. During the production of the threads, however, this thread contact can be avoided by placing the wetting agent in the rest position.
  • the development of the invention is preferably used, in which the first preparation station is selectively switchable to an operating state with thread wetting or a resting state without thread wetting.
  • the first preparation station is selectively switchable to an operating state with thread wetting or a resting state without thread wetting.
  • the first preparation station is set to a quiescent state for the withdrawal of dry threads.
  • the threads for threading could be wetted directly by the first preparation station, so that they can be safely applied against static inflation to the processing units and discharged to a waste container.
  • the thread closure during threading of the threads can preferably be improved by the wetting agent of the first preparation station being formed by a plurality of pin lubricators which are held on a common movable support. So everyone can be in a spinning position extruded threads simultaneously through the wetting agent.
  • each of the threads on the outlet side of the drafting device is wetted by the second preparation station.
  • the preparation station preferably has a stationary wetting agent with a fine-pored contact surface on which the threads can be guided in parallel together at high speeds. It is essential here that a partial wrap around the fine-pored contact surface is achieved so that adequate wetting of the threads takes place even at very high yarn speeds.
  • the preparation device is preferably formed with two separate supply units, which are assigned to the preparation stations.
  • the supply units can be connected together with a tank or preferably separated with two tanks.
  • different wetting liquids can be supplied to the threads in the first preparation station and in the second preparation station.
