  • the continuous moldings of the plurality of extrusion openings are in the conventional methods and devices by a deflection device merged and bundled. Since the stations for post-processing the EndlosformMech not usually lie in the extrusion direction, the EndlosformMech by the deflecting device for further post-processing steps, For example, washing, pressing, drying, diverted.
  • the invention is therefore based on the object, the quality of the continuous molded article without Loss in the economy of the process or the device and without one to increase additional design effort, and the flow characteristics in the Improve area between the extrusion opening and the deflection.
  • this object is achieved in that the deflection is arranged in a precipitation bath, in which immerse the continuous molded body.
  • the spinning quality is improved by that according to the invention the extrusion openings are arranged in series and the continuous moldings coming out of the extrusion openings exit, form a curtain.
  • the extrusion openings are arranged in series and the continuous moldings coming out of the extrusion openings exit, form a curtain.
  • the continuous moldings Due to the arrangement of the deflection in the precipitation bath, in which the extruded Continuous moldings are passed, the continuous moldings are then redirected, if they are solidified and mechanically loadable. This ensures that the continuous moldings not be damaged by the deflection.

  • a blowing can take place transversely to the extrusion direction to the Dry continuously molded articles immediately after extrusion.
  • the invention Method and device according to the invention can work with or without blowing.
  • the spinning system modular be built: Through the extrusion openings of an extrusion head are individual Curtains are formed, which are further processed together. Therefore, the To increase manufacturing capacity of an existing device, only need more Extrusion heads or curtains are added. This expansion option will inventively facilitated by the fact that the extrusion openings of a Extrusion head are arranged substantially in rows. To increase the Manufacturing capacity, the extrusion heads in series or in each case be arranged parallel, so that additional extrusion heads only to the existing series of extrusion heads connected or parallel to the already existing extrusion heads are added. These are Receiving devices provided in which additional extrusion heads detachable can be used or reinserted removed.
