Definitions

  • This invention relates to apparatus for spinning cellulose solutions whether by the viscose, cuprammonium or any other method.
  • An object of the invention is to enable rapid 5 replacement and quick locking of the parts of the spinning apparatus to be effected.
  • Spinning apparatus in accordance with the invention essentially comprises a spinning cylinder and a separate spinning jet head adapted to close to one end of the cylinder, and is characterized by the provision of means whereby, during the spinning operation, the pressure of the incoming spinning solution is utilised automatically to press the head to tight sealing position against the cylinder.
  • a perforated plate is disposed in the spinning jet head to offer such resistance to the incoming spinning solution that, under the pressure to which the plate is thereby subjected, it urges the head into fluid-tight engagement with '20 the cylinder.
  • the spinning jet head is so connected with the supply pipe for the spinning solution that it has limited universal movement ensuring correct seating of the head against the 2! cylinder end.
  • the head may be slidably mounted on a tubular piece, coupled to the supply pipe, the mating ends of the two being constructed after the manner of a ball joint.
  • a filter may be disposed directly in advance of the jet or rose carried'by the head.
  • the seating and sealing flange of the latter may be equipped with a yielding gasket of rubber or the like.
  • a distributor ring having a lateral inlet and a series of distributing ports opening into the spinning cylinder, balls of glass or 40 the like being heaped over the said ports to trap undesirable floating particles and to serve as quieting means for the precipitating liquid.
  • the cylinder is or may be furnished internally with a conical funnel constituting the spinning cham her, the precipitating liquid after rising through the balls overflowing into the funnel.
  • the spinning jet head may have a valve orcock to serve as an air-relief valve, and if desired as an additional precipitating liquid admission valve.
  • l5 denotes the spinning cylinder, and 4 the spinning jet head which, by means of its flange 9 balls 14 are heaped.
  • a rubber gasket I0 is adapted to seal the upper end of the cylinder.
  • the jet head 4 is slidably mouted in fluidtight manner on a tubular piece I connected to the supply pipe 2 for the spinning solution, the ,mating ends ,3 of these members being spherical so that the piece I and accordingly the head 4 are capable of being rocked in various directions.
  • a fixing screw 5 is provided, so that the members I and 4 may be locked in relative positions.
  • a pressure plate 6 is fixedly or loosely disposed within the jet head 4 and has a number of ports I for the passage of the spinning solution. Without departing from the scope of the invention the pressure plate 6 may also comprise a pressure ring with a single port.
  • a filter 8 is disposed in the widened jet space beyond the plate 6 and in advance of the spinning jet or rose H.
  • the jet head is provided with a cock I I, which may serve the purpose of air evacuation or for the admission of additional precipitating liquid.
  • the main supply for precipitating liquid is indicated as being at l2 in a distributor ring 2i closin: the lower end of the cylinder 15 and having an annular series of distributor ports l3 above which l6 denotes a spinning funnel seated in the ring 2
  • the jet head 4 with its flange 9 is firmly pressed on to the spinning cylinder l5 by the pressure plate 6, whereby a rapid, automatic and fluid-tight seal is provided.
  • the spinning solution passing under pressure through the supply pipe 2 and tubular piece I reaches the pressure plate 5, which offers a resistance in that the spinning solution can only pass through the restricted openings 1 of the pressure plate.
  • jet head are subjected to downward pressure derived from the pressure of the spinning solution and the flange 9 is accordingly firmly pressed'on to the spinning cylinder which is thus automatically sealed in fluid-tight manner.
  • the supply of spinning solution is opened first, whereupon the precipitating liquid is admitted, which carries with it the extruding filaments.
  • the conduit for the precipitating liquid is closed first, whereupon the supply pipe for the spinning solution is closed.
  • the jet head 4 may then be immediately removed to give access to the spinning cylinder I5 and funnel l6.
  • the invention permits rapid dismantling,
  • Spinning apparatus for cellulose solutions comprising a supply pipe for spinning solution, a tubular piece coupled to the supply pipe for rocking movement in various directions, a spinning cylinder open at one end to afford access to its interior, a spinning jet head slidably mounted on the tubular piece and adapted to bear on and close said open end of the cylinder, and a per forated plate disposed in the head to offer resistance to the passage of spinning solution -ada mitted to the head and thereby automatically:-
