  • FIG 1 there is shown the right hand side of a two-sided tube spinning machine of the type having one hundred forty-four spinning positions.
  • the illustrated right hand side of the machine comprises a spinning side 10, groups 11 of aftertreating tubes and a finishing and warp lforming section 12.
  • the unillustrated side is similarly constituted and for that reason, this description is confined to one side of Athe machine with the understanding that the machine on the other side of the center catwalk is, in eieet, the mirror image of the illustrated apparatus.
  • the spinning side 10 of the machine of Figure 1 includes an elongated spinning bath 13 which extends for the full length of the machine and which accommodates seventy-two spinnerets. Yarn issuing from each spinneret is led around one of the godets of the pair 14 to a hot water bath 15, back to the other of the godets of the pair 14 and then to the tube group 11 in which aftertreating is eliected in accordance with the principles of Griset application Serial No. 122,560, filed October 20, 1949, now Patent No. 2,725,276, issued on November 29, 1955.
  • Yarn issuing from the last aftertreating tube of a group 11 is discharged into the end of a large diameter drain tube 17 from which it is discharged into an elongated V trough 16 extending for the full length of the machine on the finishing side thereof.
  • the enlarged tubes 17 are ⁇ shown to small scale in Figure l.
  • the velocity at which the yarn is propelled through the treating tubes is, inter alia, a function of the length and diameter of those tubes and the speed at which the propelling and treating liquid is introduced.
  • the last sheet out of the yarn issuing from all the tubes, it is desirable that the last tube of each group near the upper end of the machine, where the warp sheet is relatively narrow, be progressively longer. Conversely, near the lower end of the machine, where the warp sheet is broader,
  • the last tube in each group needs to be' successively shorter.
  • the problem is solved by having the last tube of cach group 11 discharge into asloping tube.17 of very large cross Asection in comparison to an aftertreating tube.
  • the tube 17, which has no pressure-velocity eect on propulsion rate in the group 11 and ⁇ yet serves 'as a duct to deliver the treating liquid'and the yarn from the last aftertreating tube to the trough 16, maybe of varying length depending ⁇ on its position along .the length of the machine.
  • the shape ⁇ and position ofthe trough 15 can best ⁇ be understood by 'concurrent reference to FiguresZ to 6, iinclusive.
  • the finishing side or warp forming section 12 of -the machine includes a group of spaced vertical standards 1S and, in a row parallel'to them, Vanother group ofl vertical standards Athese standards .are positioned opposite one another six spinning p'ositions'apart.
  • the trough '16 is 'supported at spaced points along the machine fromstandards 13 and 19 in aman'ner which can best be understood by reference to Figure 6.
  • the trough is made in the form of Va Viw'ith one ventical side and "one sloping Iside. The vertical.
  • the trough is Very shallow and very narrow at :itsupSre'am end as can beuappreciated from Figures 2, 3' 1and ⁇ v6. It extends the full width of the space between standardslS and 19 at the downstream end.
  • the trough derives lfinishing liquid not only from the spout at 2d but also from th'e various tubes 17 which discharge both'the yarn and the treating liquid therein- Since the-treating liquid is llowing down hill fromthe upstream 'to the downstream end of the trough, it is .a'pparent that yarn discharged into the stream will be carried thereby to the downstream end of the machine. This is ⁇ illustrated in v Figures 3 ⁇ and 5. The slope of'the trough is calculated to be enough to make the liquid .flow therein at a speed in excess ⁇ of the speed of propulsion of ⁇ the yarns through spinning ⁇ and aftertreating.
  • the box has a screen-28 at its bottom so that the nishing liquid can go-through while the yarn will not.
  • combs such as combsn29 'and-30, are held inbrackets so that the operatormay raise manually the bundle of yarns running inkthe bottom of the trough, put thecombs in position. and then drop the yarns into the combs 'to align the warp.
  • the brackets which. support the combs are affixed lrespectively to standards18 and 19.
  • the standards 19 are provided with U-.channel brackets 31 bolted ⁇ to the .standards Aby Ibolts 32.
  • the standards 18 are similarly equipped with oppositelyfacing brackets 33 heldby bolts-34.
  • a tube such as tube 3,5.of Fgure7, is provided with flats 36 a-t Iopposite sides at bioth endstomake ⁇ a nonrotatable ⁇ tit in the brackets 3 1 and 33.
  • Apin 37 is passed through the tube 35. and the bracket 31 to lock tube 35 against axial slippage.
  • the tube 35 .has .seven holes drilled through' it to accounnof date Iseven comb teeth 38. These teeth comprise the ,side walls of a' .comb for six yarns while the bottom or bearing surface .of the comb is defined by a tube' 3.9 overlying arod 40.
  • the rod 40 is threaded at bothends and fitted with a pair of nuts at each end, Voneofwwhich shows at 41'1'11 .
  • Figure 8. ⁇ Brackets 42 and w43 are held by sctews from the tube 35 'and these brackets enc'ase the nuts at the endsof the rod ⁇ 40 whereby the rod Y40 is held in fixed position relative to the tube 35 and the tube 39 is .held tangentto theteeth 38.
  • chine the operator begins at the upstream end and raises the bundle of yarns out of the trough.
  • This bundle at the position of the upstream comb, is comprised of only six yarns. These six yarns are lifted above the level of the brackets 31 and 33, and tube 35 is slipped under them to position.
  • the operator drops each yarn between a pair of teeth so that the yarns assume the position shown in Figures 2 and 7. At this stage six ends are combed outand sixty-six ends are not.
  • the operator then takes the next comb downstream, raises the six combed yarns and the uncombed bundle of six to a position above the brackets, inserts the comb and puts the yarns between the comb teeth.
