Definitions

  • FIG. 4 APPARATUS FOR MANUFACTURING A CRIMPE ID CREPE YARN Filed Oct. 31, 1966 3 Sheets-Sheet 2 FIG. 4
  • FIG. 7 AEPARATUS FOR MANUFACTURING A CRIMPED CREPE YARN Filed Oct. 31. 1966 Y 5 Sheets-Sheet 3 FIG. 7
  • the invention relates to means for manufacturing a crimped crepe yarn, especially of wholly synthetic thread, and, more particularly, to means of this type which employ at least one twisting tube disposed on a pivotally mounted base plate in conjunction with driving and supporting means, and an endless belt to provide the drive.
  • the false twisting spindle also known as a twisting tube, rotates at a high speed of a few hundreds of thousands of revolutions per minute.
  • these high speed twisting tubes are, with a few exceptions, no longer driven directly by belts as were the lower speed spindles, i.e., those having an upper limit of around 120,000 r.p.m. Rather, these high speed twisting tubes utilize driving and supporting means in the form of friction discs, or the like, which are disposed between the driving belt and the twisting tube.
  • These known friction discs when mounted on a base plate, form a constructional unit which is generally known as a false twisting spindle assembly.
  • These assemblies can be in the form of single or double spindle assemblies, depending on whether the assembly is adapted to drive one or two twisting tubes, respectively.
  • the production of two left-hand or two right-hand twisted crimped yarns is achieved, according to the present invention, by use of a pin serving as a pivotable bearing and being rigidly connected to a support having two 3,385,047 Patented May 28, 1968 spaced limbs which are displaceable against the action of a spring, but not rotatable, along a carrier member.
  • the spring is adapted to be inserted between one or the other of the two limbs and a pin that can be inserted in the bar, and in either position, urges at least one driving whorl against the belt, the whorls to be used depending on the direction of twist desired. This allows conversion to one or the other direction of rotation in a particularly simple manner without the direction of travel of the belt having to be altered.
  • a pin secured on the support can be arranged to engage in a hole provided in the base plate of the assembly with substantial play.
  • a locating arm is spaced from the bar and arranged rigidly on the support and is adapted to engage in a hole provided in th carrier to secure the support against rotation about the bar.
  • the support can be secured on the bar by means of pins in such a position that, after the base plate is turned to its operative position, one driving whorl engages one side of the belt and another driving whorl engages the other side of the belt.
  • FIG. 1 is a plan view of the double spindle assembly of the present invention in which the driving whorls engage against the belt in such a manner that both twisting tubes rotate in the same direction to produce two righthand twists;
  • FIG. 2 is a side elevational view of FIG. 1, partly sectioned on the line II in FIG. 1;
  • FIG. 3 is a partial side elevational View looking in the direction 11 in FIG. 1, and rotated counterclockwise from the position shown in FIG. 2, the displaced position of a disengaging lever being indicated by the broken line;
  • FIG. 4 is a plan view of the double spindle assembly of the present invention in which the driving whorls engage against the belt in such a manner that both twisting tubes rotate in the same direction to produce two lefthand twists;
  • FIG. 5 is a side elevational view of FIG. 4, partly sectioned on the line IIIIII in FIG. 4;
  • FIG. 6 is a partial side elevational view looking in the direction IV in FIG. 4 and rotated 90 counterclockwise from the position shown in FIG. 5, the displaced position of the disengaging lever being indicated by the broken lines;
  • FIG. 7 is a plan view of the double spindle assembly of the present invention in which the driving whorls engage the belt in such a manner that the twisting tubes rotate in opposite directions to produce one left-hand and one right-hand twist;
  • FIG. 8 is a side elevational view of FIG. 7, partly sectioned on the line VV in FIG. 7;
  • FIG. 9 is a partial side elevational view looking in the direction VI in FIG. 7 and displaced 90 counterclockwise from the position shown in FIG. 8, the displaced position of the disengaging lever being indicated in broken lines.
  • a driving roller 2 and a supporting roller 3 are shown rotatably mounted by means of shafts 2a and 3a respectively, on a base plate 1.
  • Shafts 2a and 3a extend through the base plate to carry whorls 19 on their free ends, and magnets 4 are provided for holding in place the two twisting tubes 5 through which the threads extend during operation.
  • the base plate 1 together with the components mounted on it, forms a complete constructional unit which is mounted for limited pivotal movement about a pin 6 fixed to support 7.
  • a peg 8 secured in the support 7 serves to limit the pivotal movement of the base plate 1 by projecting into a hole 9 in the base plate.
  • the diameter of the hole 9 is a slightly greater diameter than the diameter of the peg 8, thereby limiting the range of pivotal movement of the base plate 1 with respect to support 7.
  • Limbs 18 and 18 extend from support 7 and are displacable along a bar 10, support 7 being prevented from rotating about the bar by a locating arm 11 extending from bar 18 and guided in a carrier 12 to which the bar is secured.
  • the carrier 12 has its lower end formed appropriately for the mounting of a roller support 13 carrying a back-up roller 14.
  • the carrier 12 thus forms the carrier for the complete double spindle assembly and is secured to a profiled section rail (spindle frame) of a crimped yarn machine through which a driving belt 15 travels along a predetermined line.
  • a compression spring 16 is carried on the bar 10, and abuts against pin 17 inserted in the bar. In this manner the spring 16 presses against the limb 18 of the support 7, and thereby shifts the latter until the whorl 19 of the driving roller 2 engages against the driving belt 15.
  • the spring 16 is arranged to have a working range such that whorl 19 is pressed against the belt with sufiicient force to be driven by it without slip.
  • a disengaging lever 20 which urges the driving whorls 19 away from the belt a sufficient distance to bring them out of contact with the belt.
  • lever 20 is pivotally mounted on a pin 21 on the bar 10, and has, in addition to the engaging earns 22, fiat surfaces 23 which come into engagement with the limb 18 of the support 7 on pivotal movement of the lever from its horizontal position of FIG. 2, into the position shown by the broken line of FIG. 3.
  • FIGS. 4 to 6 are views similar to FIGS. 1 to 3, but show the device converted so that the direction of rotation of the twisting tubes is reversed.
  • the opposite pair of whorls come into engagement with the belt 15 so that rollers 3 act as driving rollers, and rollers 2 act as supports for the twisting tubes 5.
  • the backup roller 14 is shifted on the roller mounting 13 to match the displacement of the base plate, the relative position between lines 18-18 and bar 10 is changed, and compression spring 16 is shifted so that it acts between pin 17 and the other limb 18' of the support to provide the engaging force.
  • the double spindle assembly is positioned on the bar 10, and the base plate 1 is turned on the pin 6 so that two diagonally opposite whorls come into engagement with opposite sides of the belt 15, causing the two twisting tubes to rotate in mutually opposite directions.
  • the base plate does not have to make any translatory movement, but only a pivotal movement necessary for causing engagement of the whorls.
  • the base plate 1 is secured against linear movement on bar 10 by means of pin 17 which now passes through a hole 24 in support 7 and engages in a hole 25 in bar 10.
  • peg 8 engages in a slot 26 adjacent to the hole 9 in order to allow the larger pivotal movement necessary for engagement of the whorls.
  • the engaging force for the whorls 19 is provided by a tension spring 27 which is hooked onto a peg 28 on the carrier 12, and a peg 29 on the base plate 1.
  • the double spindle assembly is brought into and out of action by the disengaging lever 20 which, in contrast to the previous arrangements, now also carries a roller 30 secured by means of a screw 31, as shown in FIG. 9.
  • This roller 30 engages against an abutment 32 which is displaced through the distance S by moving lever 20 to the position indicated by the broken lines in FIG. 9.
  • base plate 1 is initially removed, and pin 17 is removed from its original position in bar 10. Then support 7 is moved upward with respect to bar 10 so that hole 24 in the support 7 and hole 25 in the bar 10 are aligned. Pin 17 is then inserted through these holes and base plate 1 is replaced on the pin 6 in an angular position with peg 8 extending into the slot 26. This latter engagement permits the upper whorl on one side of base plate 1 and the lower whorl on the other side to engage the belt 15.
  • tension spring 27 is mounted on the pegs 28 and 29 to urge the whorls 19 into engagement with the belt to provide a sufiicient force to drive the above-mentioned whorls and, hence the twisting tubes 5, in opposite directions.
  • the false twisting spindle assembly according to the invention thus permits simple change-over operations to be effected according to whether two right-hand twists, two left-hand twists, or simultaneous rightand left-hand twists in the yarn are desired.
  • the present invention is not limited to the use of magnetic means for retaining the twisting tube against the friction discs.
  • the driving and supporting means for one or two twisting tubes of other known constructions could be arranged on the base plate 1, provided such arrangements permit, without the use of a magnet, the rotation of a twisting tube at high speeds of a few hundreds of thousands of revolutions a minute.
  • An apparatus for producing a crimped yarn comprising a support frame, a support plate mounted on said frame, at least one twisting tube for said yarn rotatably mounted on said plate, a pair of shafts for each twisting tube, said shafts being rotatably mounted on said plate, a roller member fixed to one end of each of said shafts and engaging said twisting tube to rotatably drive said tube, a whorl fixed to the other end of each of said shafts, a driving belt extending between said whorls, a carrier member extending immediately adjacent said frame, means resiliently connecting said carrier mem ber to said frame to urge one of at least one pair of said whorls against said belt to drive their corresponding tube, the positions of said carrier member and said support plate being adjustable with respect to said frame to permit combinations of whorls to engage said belt according to the desired direction of tube rotation.
  • said connecting means comprises a pin detachably located in said carrier member, and a spring adapted to be inserted between said pin and either end of said frame, depending on the desired position of said carrier with respect to said frame.
  • said connecting means comprises a pin extending through holes in said carrier and said frame and a spring attached at one end to said plate and at the other end to said carrier.
