Definitions

  • the variation in extrusion may beefiected by suitably varyingth'e speed at whichthe spinning :pump is driven, or'by constructing the pump to ive, a variable. output. Itis important that the spinning solution follows 'a. short path from the pumps to thejets or nozzles, and that the conduit conducting the solution to each jet or nozzle is of a rigid character, in order to preventthe damping or absorption of the pulsations before the solution reaches the jet or nozzle;
  • All the jetsor nozzles, whetherin a. single metier or machine or in a seriesxof such, which are requiredto produce the same quality of filament are supplied with-spinning solution bysimilarly operating pumps lwhich produce thesame variable extrusionirom all'the jets or nozzles.
  • the variationsindenierproduced according to the invention may appear at regular short or regular long intervals of length or'at'regularly varying intervals, and variations of different degree or extent, or both, mayappear at any desired intervals. Orone or more groups of irregularities may appear in regular sequence Orin: any desired order; or at any desired intervals. Thus, for, example one ormore short variations may alternate'with one or more longer variations, on
  • groups of short and long variations may alternate with shorter long variations or with other groups of shortand long variations, always with the object of producing a regular or systematic efiect from the alternating on periodically recurring irregularities: of denier of the filaments, yarns or threads.
  • periodical irregularities forming groups of, for example, '2, '3, 4, 6" or 10 or more variations may occur on the filaments, yarns or threads, the groups alternating with each other or appearing in any desired order according to the efiect to beproduced.
  • the Jyarns or-threads which "have received the regular irregularities as above described may be wound or twisted and-wound, for example -by means of p-spinninggdevices, .or centrifugal boxesre l U l
  • the filaments of varying denier . may be formed into yarns, either alone orwtwisted or doubled with threads of other natural or'artificial filaments or fibres. Or they may be cut or reduced doubled with the same or.:ot her yarns to form any desired type of thread.
  • the pump Showncon- 'sists' of'a plurality of plungers 4O sliding in cylinders 4
  • Projections 44 on the stems 45 of the plungerslfl engage a cam groove 46 formed round
  • the camgroove 46 is given an irregular outline considered with respect to the axial direction of the pump; so' th'at the plungers are caused to move irregularly in.
  • the nozzles supplied by each pump should be few in number --in order to; provides. short path for the spinning solution Pumps.
  • ayaryingoutput such as are described above may be usedain conjunction with pumps supplying spinning'solution to the jets at 'a regular rate, the variations injdenier being produced by the-superposition of the varying "output-from one pump upon the regular output :of the other pump.
  • two or ;more pumpsi'some or all offwhich'have a varying output may operate to supply spinning solution to oneorinorejetsr f ltwill' be understo'od that apparatus for the supply of spinning solution-such as described above is applicable to'both the dry-spinning and the wet-spinning processes of producing artificial filamentsorithre'ads.
