Definitions

  • a yarn-twisting apparatus for formation of multiple-ply thread has a nonrotatable spindle carrying at least one spool from which two strands are drawn. The strands or threads pass down through the hollow interior of the spindle and out a radial opening in a rotating storage disk, thence up around the spool or spools to a bobbin.
  • a first brake comprising a ball received in a conical or funnel-shaped seat is provided in the top or inlet end of the spindle and a second brake in the form of a compressible body with semispherical ends received between two conical seats is provided in the lower or yarn-outlet region of the spindle.
  • the upper seat of the lower brake is formed on the end of a hollow element threaded into the spindle and provided with a scale so that the axial position of its seat can be read off and set according to how much tension is to be imparted to the United tates Patent [191 [111' 42,693 Greive et al. [45] July 3,1973
  • the present invention relates to a yarn-spinning or yarn-twisting apparatus. More particularly this invention concerns an arrangement for drawing a pair of strands or threads off at least one spool and tensioning these strands or threads in the twining of them to form yarn.
  • a major problem in such devices lies in the difficulty of drawing the same amount of yarn off'each spool.
  • Various devices have been mounted atop the spindle to overcome this difficulty.
  • a flexible disk is provided which is bent to tension the frictionally engaged threads upstream of the thread brake.
  • Such an arrangement has been found to work as long as both threads are being pulled off the spools at approximately the same axial distance from the disk, and as long as the spool diameters correspond somewhat to the disk diameter.
  • the spools are mainly empty or when the yarn is being pulled off the upper region of the upper spool, such a device is almost completely ineffective.
  • a spring is provided which is fitted over the upper end of the spindle and which is shaped as a cone or a mushroom. Such a spring can deflect to the side to make up for changing tension in the yarns, but like the above-mentioned arrangement, is only effective under certain conditions.
  • 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 having a pair of rounded ends 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, the upper 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.
  • the spinning apparatus shown in the FIGURE (see the commonly assigned copending application Ser. No. 34,007 filed May 4, 1970, now US. Pat. No. 3,648,449) has a motor 3 driving a shaft 2 on which is mounted a storage drum 4 and a storage disk 6.
  • a rectangular orifice 8 opens radially from the drum and communicates with the interior of the device.
  • Rotatably mounted on the shaft is a sleeve 22 to which is secured a disk 10.
  • a rotationally fixed cylindrical sleeve 84 surrounds the disk 10 and carries magnets 12 which coact with magnets 12 in the disk 10 to prevent this latter from rotating.
  • Two yarn spools 14 and 14', one above the other and wound on respective sleeves l5 and 15, are received on a synthetic-resin sleeve 16 surrounding a tube in turn formed with an end region of enlarged diameter in which are fitted the sleeve 22 and a ring 28.
  • the upper end of the ring 28 is formed as a conical seat 30 and the lower end 32 engages the support sleeve 22.
  • An upright rod 18 supports a horizontal wire ring 20 which surrounds the upper edge of spool 14'.
  • a thread 34 is formed in the upper end of the guide tube terminating in a semicircular shoulder 36 in which O-ring is mounted.
  • a threaded portion 38 of a ho]- low spindle or sleeve 40 is received in the threaded region 34.
  • the lower end of the spindle or sleeve 40 carries a ring 42 formed with a downwardly directed conical seat 44.
  • a bullet-shaped braking element 46 comprising two telescoping cylindrical shells 48 and 48 with rounded ends 50 and 50' and a compression spring 52 is compressed between the two seats 44 and 30.
  • the O-ring 60 frictionally retains the spindle o sleeve 40 relative to the sleeve 26.
  • An adjustment ring 54 is fixed on the spindle or sleeve 40 above the sleeve 26 and is provided with a scale 56 registering with similar indicia 58 on the sleeve 26 to allow accurate setting of the braking effect of the element 46 as will be described hereinbelow.
  • a further metal sleeve 62 is formed with a central internal shoulder 70 that defines in its interior two opposite axially opening cylindrical recesses 68, the former receiving a ring 72 formed with an upwardly open conical seat 74 and the latter fitting over the upper end 64 of the spindle or sleeve 40.
  • the recess is formed at its mouth with threads 80 in which is screwed a guide ring 78.
  • a steel ball 76 of greater diameter than the axial hole 79 through the ring 78 is received in the recess between the rings 72 and 78.
  • a guide eye 86 Directly above the spindle or sleeve 40 is a guide eye 86 along with a motor-driven takeup spool 88. Virtually all of the elements described above are coaxial on the rotation axis A.
  • filaments 82 and 82 are drawn off their respective spools l4 and 14' and threaded longitudinally through the sleeves 62, 40 and 22 and passed outwardly through the port 8 and then up through the sleeve 84, through the eye 86, and onto the spool 88.
  • the motor-driven spool 88 is started rotating and the motor 3 is actuated to rotate the conical disk 6 and the storage drum 4, the remaining structure being prevented from rotating by the magnets 12 and 12'.
  • the two filaments 82 and 82 are drawn off their spools l4 and 14' they form a first balloon whose shape is limited by the ring 20.
  • the ring 78 can be removed and the ball 76 replaced with another ball of different weight.
  • the prebraking carried out at the upper end of tube 40 permits the yarns to feed at a uniform rate into the lower brake. If no such upper brake were provided the lower brake 46 would have to make up for the varying resistances of the filaments as they pull off their spools and would therefore do only a mediocre job at braking the throughpassage velocity so that the proper amount of tension is present in the yarn as it is twisted.
  • An apparatus for twisting a pair of yarns comprisan upright hollow spindle;
  • a rotatable disk at the base of said spindle having a radial opening communicating with the interior thereof, said yarns passing longitudinally upwardly to the top of said spindle along the exterior thereof, in through the top of said spindle, downwardly through said spindle and outwardly through said opening;
  • a first thread brake at said top of said spindle comprising a downwardly converging ball seat, a ball received in said seat, and an annulace having rounded ribs retaining said ball and guiding said yarns between said ball and said seat;
  • a second thread brake in said hollow spindle axially spaced from said first thread brake and close to said base, said second thread brake comprising a pair of axially open conical seats converging away from one another and a compressible body engaged between said seats of said second thread brake and pressing said yarns thereagainst, said body being formed with a pair of telescoping cylindrical sleeves having hemispherical end surfaces contacting the respective seats, and a compression spring axially urging said sleeves apart, said spindle including a tubular base portion receiving said second thread brake and an inner portion threaded into said base portion at the top thereof and carrying said first thread brake, said inner portion bearing axially against one of the seats of said second thread brake;
