Definitions

  • ABSTRACT A thread-twisting apparatus has a hollow stem through [30] Foreign Application Priority Data June 21, 1971 which the threads to be twisted together are drawn axially.
  • a pair of axially spaced thread brakes are pro- Germany 0 71 23 827.2 1 vided in the stem, and a hub carrying a thread guide, is [521 (LS. 57/58.52, 57/58.86, 57/106, ro ationally mounted on the. stem.
  • This guide is a bent wire having a C-shaped central portion embracing the Int. Cl « hub and formed with an inwardly directed finger en- [58] gaging in a radially open hole in the hub for rotational coupling of the hub and guide.
  • a rotation brake acts v on the hub and the adjustment for this brake and for one of the thread brakes can be carried out in a single References Cited UNITED STATES PATENTS 12/1922 operation whereby both braking effects'are eitherincreased or decreased simultaneously.
  • the present invention relates to an appartus for twisting yarns. More specifically this invention concerns a yarn guiding and tensioning arrangement for a double spool, two-thread yarn twisting arrangement of the type in which two threads are passed through a central tube.
  • a second independent thread brake in the upper end of the spindle.
  • a brake comprises a gravity-loaded ball resting in a conical seat to pinch and tension the yarns as they are pulled between the ball and the seat.
  • the yarns are further tensioned in the lower region of the spindle by a second thread brake comprising a bullet-shaped body which has a pair of rounded ends and which is compressed between two opposite and axially directed conical seats, the yarns being pinched at each end of the body between it and the seats.
  • the compressed body comprises a pair of telescoping cylindrical sleeves with hemispherical ends and a compression spring received between these sleeves to urge them outwardly toward their respective seats.
  • the upper seat is formed on the lower end of an elongated element threaded into the nonrotatable spindle, theupper end of the element being provided with markings cooperating with a scale.
  • the element is threaded in the spindle so that rotation of it relative to the spindle moves the upper seat axially relative to the lower seat, compressing the spring in the brake body more or less to vary the braking effect.
  • the upper brake' is mounted on this adjustment element, which itself is hollow.
  • an apparatus which hollow spindle is provided with a hub that can rotate relative to the spindle, a brake being provided between the rotatable hub and the nonrotatable spindle.
  • a thread guide is removably mounted on this hub so that the device may be used for twisting a single filament or for twisting two or more filaments, depending on how-many eyes are provided in this guide.
  • Such an apparatus is especially advantageous in installations where sometimes one and sometimes several yarns are to be twisted since simple removal or mounting of the guide allows the changeover to be executed in seconds.
  • Such a guide is necessary to keep the two filaments apart until theyenter the upright axial passage through the stem since if they touch each other just as they are being pulled from their respective bobbins it is almost inevitable that they will foul and completely upset the twisting operation.
  • the hub is formed with a circumferential outwardly open groove and with a radial notch opening intothis groove.
  • the flyer is a bent wire having a pair of arms each formed at the end with a thread-guiding eye-and both joined together at the center by a C-shaped region which snaps into the groove in the hub.
  • this C-shaped central region is formed with an inwardly directed spike-like portion which is received in the notch and rotationally couples the flyer to its hub.
  • the hub is carried on a hollow upright tube through which the filament passes.
  • a friction member rotationally coupled to the tube engages the upper side of the hub and another such member mounted below the hub engages its bottom.
  • a nut is threaded in the lower member and is nonrotatable relative to the tube which itself is displaceable axially between two positions in be called its adjustment position in which it is rotatable relative to the lower support member, its rotation will screw the nut in the lower member, displacing it therein.
  • a cartridge-type thread brake comprising an'axially resiliently compressible body bears in one direction on a seat formed in the lower member and in the other direction on a seat formed on the lower end of the tube which is downwardly biased by a spring engaging the above mentioned nut.
  • Another spring is provided between the upper member and the friction ring bearing against the top of the hub. Since the pressure exerted on the cartridge by its spring determines how far into the lower member the tube projects, the compression of the spring bearing on the hub is affected as the thread brake is adjusted. As the thread brake is loosened the tube rises in the lower member, which decompresses the spring bearing on the hub. On original assembly a specific ratio is established between these two springs, with this ratio remaining essentially constant on adjustment of the device.
  • FIG. 1A is a vertical section through a first embodiment of the apparatus, according to the present invention, in the operative position;
  • FIG. 1B is a similar section showing another embodiment of the device in the adjustment position
  • FIG. 2 is a section taken along line II-II of FIG. 1A;
  • FIG. 3 is a perspective view illustating how the apparatus according to the present invention is employed.
  • a pair of bobbins 47 and 48 of yarn are mounted one above the other on a common stem 11 and their respective filaments 47' and 48 are drawn through eyes in the end of a guide 49 carried on a hub 39 rotatable on this stem 11. Thence the two filaments 47 and 48 are drawn through this stem 11 and pass out through a hole 50 in a flyer 50 which is driven by a motor 51. This twists the two filaments together. Thereafter they pass up around the entire assembly forming a ballon and through an eyelet 52 to a takeup spool 53 driven by a motor 54.
  • the amount of twist imparted to the two filaments is determined by the rotation rate of the flyer 50 and the takeup speed of the spool 53.
  • the spindle 11 is prevented by magnets or the like from rotating and contains two thread brakes which maintain a predetermined amount of tension in the filaments to ensure even twisting and to prevent the balloon from becoming excessively large.
  • the stem 11 is mounted on a support rod 12 which is carried on the flyer 50 and carries a lower sleeve member 13 and a seat 14 with a conical surface for a cartridge brake 15.
  • This brake 15 is an axially elongatable cartridge formed by two telescoping sleeves 15 and 15" between which is provided a compression spring 15", each sleeve and sleeve 15' having a hemispherical end bearing on its respective conical seat.
  • a tube 17 has its lower end received in the lower member 13 and passes through a cover 19 into the lower end of an upper sleeve member 29 to which it is rotationally secured by a set screw 30.
  • This tube 17 is provided with a snap ring 20 which prevents it from being pulled axially out of the lower member 13 by engagement with the screwed-on cover cap 19.
  • an axial groove 21 is formed in the tube 17 into which fits a tongue on an adjustment nut 24 which is threaded into the lower member 13 and surrounds the tube 17.
  • the tube 17 carries on its lower end a seat 16 for the upper hemispherical end of the braking body 15 and a ring 22 which is rotationally coupled to this seat element 16 and which is formed with axially extending fins fitting into complementary grooves 46 formed on the inside of the lower member 13.
  • These grooves 46 only extend part of the way up in the member 13 so that in the FIG. 1A position the ring 22 fits into them and is 7 therefore rotationally coupled to them whereas in the FIG. 1B position (adjustment position) they do not engage each other and therefore the tube 17 can rotate relative to the element 13.
  • FIG. 1A shows how a ball brake 31 as described in the abov e iiieiifioned Ser. No. 1881335 application can be used here.
  • a cartridge brake 32 identical to the brake 15 may be employed,
  • a seat 28 is provided at the upper end of the tube 17 for the brake. All of the seats 14, 16, 28, and even 33 can be made of a synthetic-resin material or a particular metal whose friction characteristics are especially adapted to the particular needs.
  • the hub 39 for the wire guide 49 (FIG. 2) is carried between the elements 13 and 29.
  • This hub is a short sleeve which is rotatable relative to the tube. 17 and which rides on the cap 19 via a friction washer 38 and against whose top another washer 35 bears.
  • the member 29 receives the upper end of the hub 39 at 34.
  • the inner walls of this member 29 are once again formed with grooves 37 which interfit with the washer 35 so that the washer 35 is rotationally coupled to it.
  • a spring 36 is braced between the washer 35 and the member 29 to urge this washer 35 against the hub and thereby brake its rotation relative to the member 29.
  • a radially inwardly extending projector 43 of the wire guide extends into a radially outwardly open hole 43' of the hub.
  • the eye 33 is removed and a heavier or lighter ball is exchanged with the existing ball.
  • the brake 32 is adjusted by screwing the eye 33 in or out.
  • the brake 15 is adjusted by grasping the upper member 29 and lifting it until the ring 22 is pulled out of engagement with the grooves 46 in the lower member 13. Then, while holding the device in this adjustment position as shown in FIG. 13 with the spring 23 compressed, the upper member 29 is rotated relative to the lower member 13 to screw the nut 24 in the lower member 13. Screwing the nut 24 down in this lower member 13 will compress the cartridge 15 more and thereby increase the braking effect and vice versa.
  • a guiding and braking arrangement for a threadtwisting apparatus comprising:
  • a thread guide removably mounted on and rotationally fixed to said hub; and means for braking rotation of said hub relative to said stem, said guide being a bent wire having a C- shaped central portion snugly embracing said hub.
  • said one of said thread brake comprises a pair of axially open conical seats and a compressible body engaged there between.
  • said braking means includes a first spring bearing axially against said hub.
  • a guiding and braking arrangement for a threadtwisting apparatus comprising:
  • said thread brakes interconnecting one of said thread brakes with said braking means for simultaneous adjustment of both, said one of said thread brakes comprising a pair of axially open conical seats and a compressible body engaged there between.
  • said braking means includes a first spring bearing axially against said hub.
