  • Fig. 11 is a'n enlarged detail elevation of change-speed mechanism also illustrated in Fig. 8.
  • the method of winding will best be underas applied l stood by concrete examples practiced by apparatus of familiar types modified 1n accordance with the invention, for examplefor rewinding individual yarns singly, or in multiples of only two or more, from the large multiple package; or for. sk eining singly, doubly or in triples; or rewinding, inspecting and piecing-in in a multiple yarnk sheet or run itself rewound in multiple.
  • FIGs. 1 to 5 a well-known and typical Winder forwinding cross-,wound cheeses 34 of single or double or triple yarns at constant but adjustable surface speed by driving contact of each winding package with a tractor roll 1 is illustrated in Figs. 1, 2 and 3.
  • a winder of the Foster type selected for illustration, comprises a series of aligned tractor rolls 1 for driving the winding cheeses 34, said rolls being concentric with a shaft 2 in turn driven byv a main shaft 3, which receives its motion from a constant speed pulley 4, driven by a belt 5, all as best shown in Figs. 1 and 3.
  • the machine is provided with ⁇ , a supplementary frame 6 and a gear train 7 which is driven by a sprocket 8, and a chain 17 presently referred to, for the purpose of providing a positive drive for the unwinding yarn mass at a i speedl related to the speed of the main shaft 3.
  • the gear train 7 transmits motion from'the sprocket '8 to the shaft 9, which extends' .lengthwise of the Winder frame and which is journaled at intervals yin frame members 10.
  • the frame members are disposed in pairs (but one pair being illustrated) and are furnished with upright slots such as 10a for the reception vrespectively of the opposite ends of the spindle 11 central in a dresser spool 12.
  • the dresser spools may be of any usual ⁇ form, comprising the shaft or spindle 11, or a hole for such a spindle, and the spaced heads 13 and 14 between which the yarn is wound under tension, the several yarns being in a series of llaterall thin masses 15, usually cross-wound, a ⁇ n in close lateral contact.
  • the weight of the dresser spool is'supported by a tractor roll 16 fast on the shaft 9 between the frame members 10. This roll turns the dresser spool by contact with the general surface of the winding comprised of the several yarnl masses 15.
  • the chain 17 for driving the sprocket wheel 8 and positively rotating the unwinding mass 15 receives its motion from a sprocket wheel 18 secured to the shaft 3, which is driven by pulley 4.
  • a cone pulley 19 is also secured to the shaft 3 and transmits motion by means of a belt 20 to a cone pulley'21 mounted upon a countershaft 22'.
  • the winding tractor roll shaft 2 receives its motion from the countershaft 22 by means of a belt 22a trained about pulleys upon the respective shafts.
  • the speed of shaft 2 is adjustable in relation to that of shafts 3 and 9 by change of thel position of belt 20.
  • the belt 20 may be shifted upon the cones 19 and I21 for varying the speed of countersliaft22 for this urpose by a sliding belt shifter 23, as usua which may be actuated, Fig. 5, by a link 24 connected to a crank pin 25 carried by a toothed disk 26. This disk may be turned by means of a worm 27 actuated b a hand wheel 28.
  • Eac of the several yarns from the dresser spool passes up through pig-tail guides 29 and 30, mounted upon rails 31 and 32 respectively, on its way to the winding yarn masses 34. These yarn masses are formed upon spindlesA 35 and are supported and driven by engagement with the tractor roll 1.
  • the dresser spool spindle is driven at a constant surface speed by contact with the unwinding tractor roll 16, while the individual yarns are Wound upon their respective yarn masses by contact with the tractor rolls 1, at a speed set at a slightly greaterrate than the unwinding speed by adjustment of the hand wheel 28.
  • the surface speeds of the unwinding and winding yarn packages are thus so related as to maintain a constant and predetermined tension upon the yarns, which tension is measured by the increment or ratio of winding to unwinding speed.
  • Any desired number of unwinding spools may be arranged upon the shaft 9, in accordance with the length of the Winder and the number of ends wound upon each unwindmg spool.
  • the multiple or parallel-wound unwinding package may have its yarn individually re-wound in skeins by the application of the same priny ciples.
  • a frame A may be provided with pairs of supports or brackets 46, 47, of which but one pair is illustrated. Each of these brackets 1s furnished with a guide slot 48 for the reception of an end 11 of the spindle of an unwindlng multiple wound yarn package, such as a dresser spool 13, 14, 15.
  • the weight of this spool is supported by a tractor' roll 50 so disposed that the yarn mass 15 upon the spool contacts directly with its peripheral surface.
  • the tractor roll 50 is mounted upon a shaft 49 parallel to the shaft 42 and turning in bearings in the frame members 46, 47 and in a bearing 11 at its out-board end.
  • the shaft 49 is provided with a cone pulley 52 and the shaft 42 is provided with a complementa] cone pulley 53.
  • a belt 54 encircles the cone pulleys and transmits motion from the shaft 2 to the shaft 49.
  • the position of the belt 54 is controlled. by a sliding belt shifter 55 adjustable by a hand wheel and screw 55.
  • the machine may be provided with the usual traverse rail 56 having the pig-tail or other guides 57 through which the yarn i/ passes on its way to the reel ⁇ The yarn is guided from the unwinding mass 15 to the guides 57 by other guides 58 carried by a stationary rail 59.
  • the spood 13, 14 and yarnl mass 15 rests by gravity against the surface of the tractor roll 50.
  • the drive belt when on the fast pulley 44 turns the reel 3 at substantially uniform speed, and drives the shaft 49 and tractor roll 50 at a related speed according to the position of belt 54..
  • the position of the belt 54 is so adjusted that the surface speed of the unwinding mass spool is a little less than that of the reel, to maintain a slight and uniform tension upon the yarn between the dresser spool and the reel.
  • the reinspection of yarn is commonly accomplished by mounting one or more dresser spools in the inspecting spooler, drawing off yarnsI from the several spools to form a sheet or run before which the operator sits, and rewinding the yarns after inspection -upon a dresser spool, section beams, or one or more warp beams.
  • the inspecting spooler must be adapted to be instantly and frequently stopped and started during the inspecting operation. In starting an added burden is put upon the yarns due to the inertia of the unwinding spool, while the momentum of the latter causes it to overrun when the machine stops, thus slackeningr the yarn tension and sometimes tangling the yarns.
  • the end frame members B of a Asuitable spooler, Fig. 8, are each provided with a downwardly and forwardly inclined rail 62, and these rails are furnished respectively with journal openings for the reception of the opposite ends of two series 63,
  • a bracket is mounted upon each of the members 62 adjacent to each of the bearings forthe shafts 63. Similar brackets 65 are also mounted on member 62 in association with the bearings for each of the shafts 64.

  • the slots 67 constitute guides to position the opposite ends 11 of the spindles of unwinding yarn mass 15 on dresser rolls 13, 14, such as above described.
  • the slots 68 receive the opposite ends of the spindles 11 of similar winding dresser rolls for the winding yarn mass 15.
  • the slots 67 are open at the top and bottom so that the weight of the unwinding dresser rolls is permitted to rest upon the traction rolls 75 carried by the shafts 63 and disposed immediately be ow the respective dresser rolls. In the same manner the weight of the winding dresser rolls is' borne by the tractor rolls 76 mounted on the shafts 64. By this arrangement, rotation of the tractor rolls is frictionally transmitted to the dresser rolls by contact with the surface of the-thread mass.
  • Each of the shafts 63 is provided with a bevel gear 77 which meshes with a bevel gear 7 8' on a drive shaft 79.
  • each shaft 64 is provided with a bevel gear 8O meshing with a gear 81 upon a drive shaft 82.
  • ⁇ A gear 83 is secured to the forward end of the drive shaft 82 and meshes with a-gear upon the drive shaft d of the machine which is driven at substantially constant speed by means of a pulley p and belt, (not shown).
  • Suitable change-speed 'adjustment is provided between the drive for rolls 76 and the drive for rolls 75.
  • the forward end of the shaft 79 may be furnished, for example, with a gear 84 which meshes with a gear 85 carried by a counter-shaft 86 mounted in a bracket 87.
  • a cone pulley 88 is secured to the countershaft 86 and a complemental cone pulley 89 is mounted on the rear end of the shaft 82.
  • a belt 89a is interposed between the cone pulleys 88 and 89 and transmits movement from the latter to the former.
  • This belt may be shifted to vary the speed of the pulley 88 relatively to the pulley 89 by means of a belt shifting fork 90 carried b v a slide melliber 91.
  • the position of the latter is determined by a screw threaded rod 92 actuated by a hand wheel 93.
  • Each of the brackets 66 is provided with a supplemental bracket 94 having a bearing for the shaft of a traverse guide roll 95, Figs. 8 and 10. Theserolls have cam slots 95a for distributing the yarn upon the winding diessver S9001. nach 'braeka 94. is row/1aed wah a guide eye 96 through which t e yarn passes on its way to the cam slots 35.
  • the unwinding dresser spoolsthe4 yarn Y passes overv uide rolls 97, 98 and 99 andpthen downwar ly to form the vertical sheet 100 before which the' operator is' positioneld. At the lower edge of this sheet the yarns pass about guide roll 101, thence over guide rolls 102 and thence to the guide eyes
  • the winding tractor rolls 7 6 are slightly larger than the unwinding tractor rolls 75 so that'when the transmission at 88, 89 is neutral a constant increment of tension, depending on the length between winding and unwinding masses, is exerted upon the yarn between said masses.
  • a variable effect of tension may be obtained by adjusting the belt 89, since by this means the speed of the drive shaft T9 may be varied relatively to that of the drive shaft 82.
  • the relative speeds of these shafts is so deter ⁇ mined as to maintaina constant and predetermined tension upon the yarn, and the degree of tension may readily be variedin accordance With'the typeof yarn being wound and the impressed or ori inal tension.
  • That method of tensioning yarn while winding it from one package to another which comprises positively driving both the winding and unwinding packages, the surface speed of the winding package being greater than that of the unwinding package.
