Definitions

  • This invention relates to spinning apparatus. More particularly the invention relates to apparatus adapted to the simultaneous spinning and twisting of a plurality of yarns under similar conditions, the apparatus being particularly adapted in a process where the plurality of spun filaments having a twist are brought together to form a strand which is then subsequently advanced in the form of a helix or a plurality of sequentially formed helices which are subjected to various processing treatments then separated prior to collection.
  • Rotating seals irrespective of construction, generally eventually develop leaks resulting in solution losses and possible contamination of the solutions. Rotating seals also generally require separate or additional driving means to the driving means for a spin pump.
  • This invention advantageously provides for a multiple yarn spinning apparatus of compact and simple construction where a minimum of seals against the escape of a spinning solution are provided, where each rotating extruding device has its own pump, and where each is subject to the same constant conditions, and all pumps being commonly driven and supplied with a spinning solution from a common source.
  • the solution to be extruded by each spinneret and formed into yarns is passed through a path leading through a solution gear measuring means within the body of the apparatus; the path, for a portion of its length, extends through the core or shaft of one of the measuring gears of a gear pump, thence through a conduit joining the path to a spinneret that is mounted on the extension of such conduit.
  • the conduit Since the conduit is joined to the core of one of the gear pumps it rotates with the gear to which it is joined.
  • the seal is therefore in the pump housing.
  • a plurality of such rotating spinnerets can be positioned in each pump block, and the pumps are combined in a manner so that each of said plurality of pumps and spinnerets is driven by the same power source, and the yarn solution to be extruded is fed to each spinneret from the same internal solution supply source to each gear pump and through each gear rotated spinneret.
  • the entire 2,715,753 Patented Aug. 23, 1955 "ice assembly may be advantageously mounted relative to a trough containing a filament coagulating liquid in which the plurality of spinnerets are positioned. Further, when the spinnerets are positioned in the coagulating liquid they are all adapted to be rotated at a similarly constant predetermined rate during spinning to impart the same twist into the spun yarns to facilitate their separation from a previously formed bundle or strand.
  • Figure 1 represents in schematic form a multiple-end spinning and processing apparatus
  • Figure 2 represents the multiple-end twisting and spinning unit of the apparatus
  • Figure 3 is a section taken across line 33 of Figure 2 of the multiple-end twisting and spinning unit.
  • a plurality of rotating spinning nozzles 12, 13, 14 mounted in a housing 15.
  • the housing 15 is pivotally supported on a shaft 17 to permit the removal of the rotating spinning nozzles for inspection ptuposes or for replacement reasons.
  • the spinning nozzles are rotated at nominal rates so as to impart a twist of about one turn for every 70-200 inches of running length of yarn.
  • the power for rotation of the gear pumps within the housing is supplied by a drive shaft 18.
  • the formed yarns 19, 20, 21 are passed about a roller 22 positioned in the bath 11.
  • the yarns are combined into a strand or bundle 23 at about the point of contact with the take-up reel 24. While on the reel 24 the strand 23 is formed into a helix and advanced therethrough. From the reel 24 the strand is led to a subsequent reel 25 over which it also is advanced as a helix, and from this reel the strand is led to other similar reels, if desired, and finally to a drier reel 26 whereupon it is subjected to heat.
  • the dried strand 23, formed of three twisted yarns 19, 2%, 21 is led through a guide 28 positioned beyond the drier reel 26 and separated. The individual yarns are then led through the guides 31, 32, 33 to nip-rolls 34, thence through guides 35, 36, 37 onto take-up apparatuses 38, 39, 40.
  • the separation of the strand 23 is advantageously efiected by a backing up of the twist in each yarn through the insertion of a pointed instrument into the travelling strand so that the twist will group the filaments forming such yarn.
  • the yarns thus identified and separated are then led to their corresponding take-up apparatuses.
  • the spinning and twisting apparatus advantageously is formed of a plurality of gear pump units having integrated or joined with one of its pumping gears a mass tube having mounted thereon a spinning nozzle.
  • the housing 15 contains three individual, identical gear pump units 42, 43, 44.
  • the units advantageously may be of the type generally commercially used and known under the trade name as Zenith pumps.
  • Such units generally comprise two rotating gears in meshing are in turn driven by a common drive 18 (only generally shown 1n Figure 1) having mounted thereon gears 56, 57, 58 w1th which they mesh when in driving relation;
  • the spinning solution follows a tortuous path through each pump .unit and through each pair of measuring and forwarding gears of each pump unit;
  • the several solution passages or paths are joined with a common solution source as the manifold orconduit 63.
  • Conduit 63 is joined to the initial supply source 59 through passage62 and header 60 within thehousing 15.
  • the solution path encompasses the supply header 60, passage 62,
  • header 6 the path to and about each pair of pumping gears and therefrom through passages65, 66, 67, through the core; of shaft of pumping gears 46, 48,50 into the l respective ,outlets, conduits or mass tubes 69, 70, 71 to the spinning nozzles 72, 73, 74.
  • Each pair of pumping gears is supplied by itspassage oining the'header 63.
  • Gears 45, 46 are supplied by passage 65;
  • gears 47, 48' are supplied by passage 66; and
  • gears 49, 50 are supplied by passage 67. After passing through the gears of each pump the solution is forced through outlet passages or mass tubes 69, 7G, 71 respectively.
  • the flow path of each passage 65, 66, 67 is generally reversible and their outlets pass through the core or shaft of the pump gears 46, 48, 50.
  • the core or hollow shaft of each gear 46, 48 and is joined with the mass tubes 69, 7t), 71 respectively, and each mass tube having at its end spinnerets 72, 73, 74 respectively.

  • the viscose spinning solution is .suppliedto :the header 61 by the supply inlet 59, thence it flows through passage .62 to the short interconnecting passage 64 into general header 63.
  • the header 63 is tapped by the tortuous path 66which supplies the spinning solution to the gears 47, 48,
  • the path passes through the gears reversing itself to an extent, as shown, underneath the pump gear 48, and then through the core or shaft 55 of the gear into the mass tube 70.
