Definitions

  • the invention relates to a device for manufacturing artificial silk, in which the threads freshly spun are for the purpose of being consolidated conducted througha hardening liquid.
  • a device in which the hardening liquid is in a trough which isfixed in place and which extends throughout the entirelength of the spinning machine, and vwhich is provided in both side walls with narrow slots open above, through which the artificial threads are passed. A portion of the hardening liquid in the trough flows away continuously through these slots and is continually replaced by a suitable injux.
  • the trough may either be provided with transverse partition walls or better still be subdivided into a number of individual troughs, each of which suitably extends over only one bundle of threads and' accordingly possesses only one narrow entrance slot and exit slot for the bundle of threads in question.
  • Thissubdivision intoindividual troughs provided with narrow passage-slots has in addition to the well-known advantages of the trough and ofits slots the still further advantage that the mass to be reciprocated during the/ passage of the thread, particularly the 246,565, and in Germany February '1, 1927.
  • the hardening liquid passing out of the trough slots may moreover suitably be further utilized by being conducted after leaving the trough on to the reel or on to the threads of artificial silk situated thereon.
  • the whole width of the wound up artificial threads is thereby sprinkled.
  • the slot-edges may consist of acid-resisting steel, but the employment of glass, porcelain, and other hard acid-resisting materials has proved suitable.
  • the employment of glass, porcelain and the like is particularly advantageous when the slot-edges consist of the same material as the. trough itself or even form an integral part of the trough.
  • the trough-slots themselves may serve as thread-guides in which case care must be taken that sharp corners which might possibly injure the thread are avoided at the slots.
  • the trough is made with slot-edges of porcelain or glass this end, as canbe readily be seen, can beattained in a, simple and perfeet manner.
  • v Fig, 1 shows a vertical cross-section through the essential parts of the spinning device in the plane of the thread
  • Fig. 2 an elevation from the. side of the Figs. 3 and 4 show the construction of the trough and of the return channels appertainin thereto in a single piece.
  • 1g. 5 shows a vertical longitudinal section through a trough extending across the by these means the level of the liquid in the trough is kept at'about the height indicated by the mark m.
  • a a narrow slot 0 which is bordered by the two shanks of an upright U-shaped piece e which in its turn is located in the wall of the trough d.
  • the troughitself consists for its part advantageously of glass, porcelain or other acidresistin material; likewise the piece e serving to orm. the edges of the slot.
  • Said piece may nevertheless consist advantageously of acid resisting steel or of other suitable elastic material, and by virtue of its elasticity may be connected with the troughin such a manner as to be capable of being exchanged.
  • the edges ofthe slot may be formeddirectly by the trough I wall, the special piece 6 being dispensed with.
  • the slots 0 serve for'the passage of the thread I) while simultaneously also a portion of the hardening liquid flows away outwards through these slots.
  • the trough is provided at each end with a beak-shapedoutlet 17 by means of which the escaping hardenin liquid is conducted into a sloping channel which is situated under said outlets and which is embedded in the beam 9, and from the latter on to the reel f or on to the thread wound thereon, so that there takes place an additional after-treatment of the thread on the reel.
  • 'I'he beam g is mounted at its ends,with the aid of a roller 9, on a fixed support 7- and is connected with a driving-cam h by means of which it can be reciprocated transversely with regard to the threads in a horizontal plane, in order thereby to effect with the aid of the trough-slots which serve as thread-guides the ordinary cross-winding of the threads on the reel.
  • Fig. 5 shows a trough m extending throughout the entire length of the spinning machine, subdivided into a number of individual troughs by means of transverse walls y, parallel with the threads. It will readily be understood that by subdividing the trough like this, an overflow of the hardening liquid at the ends of the trough, owing to the movement of the liquid in the directions indicated by the arrows, will be prevented. -It is not necessary that the subdivisions of the trough should be separated from each other entirely, but merely as much as is needed to calm down the movement of the liquid, and to prevent it from overflowing. Thesubdivisions may communicate, as shown, thereby assuring .for the liquid the same level in all parts of the trough.
  • a reciprocable trough for holding the hardening liquid adapted for horizontal reci' rocation cross-wise of the thread travel, t e front and rear cross-walls of the trough having slots for the overflow and discharge of the hardening liquid and serving also as' guides for the thread or threads, and means for reciprocating said trough.
  • a reciprocable trough for holding the hardening liquid adapted for horizontal reciprocation crosswise of the thread travel, the front and rear cross-walls of the trough presenting combined thread slots and overflow gutters, means for feeding hardener to the trough, means for reciprocating the trou h, and artition walls in the trough arranged cross-wise of the thread travel.
  • the reciprocable hardening trough is subdivided into a series of individual troughs, each one of which presents combined thread slots and overflows in its end walls, and cross walls throughout the series guides o acid-resisting material.
  • a reciprocatory trough for holding the hardener adapted for horizontal reciprocation III transversely to the threadtravel, the inner U and outer end cross-walls of the trough presenting combined thread and overflow slots of less depth than the depth of the trough,
