Definitions

  • This invention relates to apparatus for producing artificial textiles. More particularly, it relates to new and improved spinnerettes and the mountingthereof in spinning machines for producing artificial textiles.
  • the spinning solution is fed through pipelines from the tanks in which it has been stored to a distributing pipe running the lengthof the spinning machine. From this feed line, manifold lateral branches lead to the spinning pumps whichdeliver a constant and unvarying amount of solution through the spinnerettes per unit of time. Normally, the pumps force the solution through a filter, from which thesolution passes through a glass tube, commonly termed a gooseneck,
  • male member appropriately secured to the gooseneck and. was secured in position by a flange at the top. of a nut (female member) which threadedly cooperated with v the male member.
  • spinnerettes having several thousand orifices such as, for example, 5000 to 10,000 or even more, are used.
  • spinnerettes are of greater dimensions but, in order to utilize them to a maximum, it is necessary that the orifices v extend almost to the edge of the skirt.
  • An object of this invention is to provide a new and improved spinnerette.
  • Another object of this invention is to provides. more economical spinnerette.
  • a further object of this invention is to provide a new and improved means for mounting the spinnerettes in position on the gooseneck.
  • a spinnerette in the form of a perforated plate having an annular depending skirt and disposing said skirt on an exteriorly threaded portion of a holder which, in turn, is removably (threadedly) secured adjacent the bottom thereof onto a support appropriately secured to the gooseneck.
  • a locking ring which binds the skirt to the threads of the holder, secures the spinnerettein position on the holder.
  • the holder and support are hollow, and the holder together with the spinnerette mounted thereon can be removed from the support as a single unit.
  • the holder is also provided with means whereby a protectivecap can be removably secured thereto when the spinnerette mounted on the holder is n ot in use, such as after the spinnerette has been cleaned.
  • a protectivecap can be removably secured thereto when the spinnerette mounted on the holder is n ot in use, such as after the spinnerette has been cleaned.
  • the holder 9 is interiorly threaded adjacent the bottom thereof whereby it is threadedly secured on the support 4.
  • the holder 9 is provided with spurs l0 and H and a milled surface l2, for reasons which will hereafter appear.
  • the spinnerette holder 9 is formed at the top thereof withan ,extension [3- which is threaded on the exterior surface thereof, as indicated by the reference numeral l5.
  • the spinnerette generally indicated by the reference numeral 14 is provided with a multiplicity of spaced orifices 20 and-an annular depending. skirt 2].
  • the depending skirt 2! of the spinnerette l4 is'tlisposed on the threaded portion l5 of the extension KB.
  • a locking ring l6 cooperating with the skirt 21 causes the metal of the skirt 2! to .bindwith the threads l5 whereby its "immobility'and the tightness of the joint are insured.
  • Ashoulder 22 limits the downward movement of the looking ringlBwhenitisapplied.
  • extension I3 flares outwardly in the direction toward the spinner ette so that the spinning solution will;:beI-fed to all of the orifices including those adjacent the skirt.
  • the holder 9 is provided with a second shoulder 23 which cooperates with the top of the sup-y port 4.
  • the spinnerette holder 9 When :for any reason the-spinnerette has to be replaced, such as when it becomes clogged, the spinnerette holder 9 is gripped at the mille'dportion l2 and manually manipulated so as tounposition-thereon from the support 4.. .Afteiremoval, another assemly. of the spinnerette' holder with the spinnerette secured in position thereon is screwed into position on the support 4. I The spinnerette can be cleaned. while it is mounted on the support. Generally, aftera spinnerette is cleaned, it is not immediately .restored to -use. Since the spinnerette orifices must be kept clean, the instant invention provides means,
  • the protectivecap I! is preferably ,made of any suitable material, such aslaluminum, and .of the form and .shape generally shownflin Figure 2.
  • the cap-ll is formed with a shoulder I81;
  • the innerdiamete'r of thetop ofthecap above the shoulder 18 is substantially the same as the top of the spinnerette, and the dia-meterof the skirt of the cap below the shoulder is such that,
  • the peripheral wall of the ,cap l! is .provided with a p'airiof oppositely disposed bayonet slots 19 designed to cooperate with the spurs l0 and II of the holder 9.
  • the protecting cap 11 is secured on the outside 'of. the holder .9 and protectsthe spinnerette so that no access thereto canbe had by dirt, and particularly .dust. .When the assembly is desired tobe used, theprotective cap I] is removed.
  • the skirt of the spinnerette is bound to ,the threads [5 of the extension 13. This requiresthe skirt tobe made of a sufiicient thickness to withstand such action- Theincreasein the metal requiredby' this is minorcompared-to the fact that the sp'innerette does not require, and is therefore not formed with, a bottom [outwardly extending flange as was necessary with the prior art spinnerettes.
  • the support and holder can be made of any appropriate material, such as metal, for example Monel metal, or'of plastic.
  • the holder 9 is made of metal.
  • the invention provides a spinner'ettewhich does not have a-bottom flange, which'characterized the-prior art spinnerettes. As a consequence;
  • the holder and spinnerette can be removed from and quickly replaced as a single unit on the support carried by the gooseneck.
  • a feed tube for the spinning solution an annular support attached to the end of said tube, an annular spinnerette holder threaded onto said support and having an internal shoulder engaging the end of said support for positioning said holder, said holder having an inwardly offset, upwardly extending flange forming an external shoulder, a spinnerette comprising a plate formed of a metal semovable closure cap having a depending skirt extending over said ring and said holder and removably secured to said holder.
  • a spinnerette comprising a plate formed of a metal selected from the group consisting of platinum and platinum alloys, said plate having a flat top wall provided with a plurality of holes for the extrusion of the spinning solution and a depending interiorly threaded unfianged skirt, a hollow 'spinnerette holder having an externally threaded extension adjacent the .top thereof on which said skirt is screwed and a clamping ring disposed around the skirt and exertingpressure to bind said skirt with i the threads on said extension, said holder being 1 interiorly threaded adjacent the bottom thereof,
