Definitions

  • This invention relates to an improved construction of a nozzle head for the artificial silk stretch-spinning process.
  • the spinnerette is directly attached to the so-called nozzle head which carries the supply pipe for the solution to be spun and a stop-cock and at the same time serves as the upper or rear closure member for the spinning vessel.
  • the supply pipe is usually widened to a flow-chamber just before the spinnerette so as to supply the spinning solution to the spinnerette in a uniform current.
  • the spinnerette provided with a flanged-over margin is firmly mounted on the end of the nozzle head.
  • the spinning solution has the property of hardening owing to evaporation of the solvent. If the spinning devices are stopped, adhering, encrusted layers of hardened spinning solution are formed where the spinning solution comes into contact with th air and, therefore, more particularly at the spinnerette. These layers are the more extensive the greater the surface of contact between the spinning solution and the air.
  • the nozzle head according to the present invention consists of two parts which are screwed together, the lower of said parts, i. e., the front portion, constructed as a spinnerette holder, holding the spinnerette, and the upper or rear part having .a narrow bore.
  • the arrangement of the special spinnerette holder enables the flow chamber for the nozzle to be arranged in the spinnerette holder. It is just this widening which, owing to the residual solution remaining behind, most readily leads to contamination of the spinning solution and must, therefore, be carefully cleaned. Hitherto this could only be carried out with the necessary care with difiiculty, since it had to be effected on the machine itself.
  • the spinnerette holder according to the invention can be cleaned in the simplest possible manner after unscrewing by treatment with suitable solvents.
  • the cleaning can be carried out not on the spinning machine but apart from this while in storage, the spinning machines are, as a result, better utilized since the time necessary for cleaning is dispensed with. It is only necessary to screw the already cleaned spinnerette holder on to the nozzle head after the contaminated spinnerette holder, or a special closure cap provided for when the machine is not in operation, has been removed.
  • Figure 1 shows in elevation a nozzle head having a screwed-on spinnerette holder.
  • Figure 2 shows a section along the line A B of Figure 1.
  • the nozzle head consists of an upper or rear so I portion 3 attached to the spinning machine and the nozzle holder 10 capable of being screwed thereon.
  • the upper or rear portion 3 is provided with a bore 1 for conducting the spinning solution to the nozzle, and a conical bore 5 vertical thereto for accommodating the stop cock 2.
  • the lower end 6 of the portion 3 of the nozzle is made of chemically resistant material, e. g. of non-rusting steel.
  • the spinnerette '7 provided with flanged-over edge 8 is firmly drawn on to the spinnerette holder 10-, so that'a flow chamber 12 is formed which is closed-in on *all sidesl
  • the spinnerette holder 10' issc'rew'ed'on toth'e' nozzle head 3 and at" the same'tirne"abuts tightly againstthe seal-- i'r'ig surface'13 thus"prevnting entrance of spinning"s'oluti'on which 'can pass through the'bore chamber 12.
  • the spinnerette holder 10 is provided with nose members 9 for the purpose of firmly drawing on the same by means of a key.
  • NVhat I claim is: i r
  • a nozzle head for extruding artificial products comprising, a unit for supplying the solution to be extruded, a unit detachably secured to said first unit, said second unit comprising a disc perforated to form the artificial-products, and a third unit which may be -substituted for said second unit to stop the flow of the solution when said second unit is removed.
  • nozzle-head for a stretch-spinning apparatus comprising, in combination, an upper orrear portion provided with a narrow supply duct, a spinnerette holder adapted to be screwed thereon, said holder being connected to the supplymduct through a narrow bore, the abutting surfaces of the upper or rear portion and the spinnerette holder being in- 'such tight'contact that thepa'ssage of spinning-solution is-prevented, and a spinneretteprovided 'with perforations.
