Definitions
- the present invention comprises a novel twisting or plying device for textile strands.
- the new device has a high output per unit floor space, is simple and economical to manufacture and to operate and produces yarn of uniform quality and twist.
- the new twister or plyer may be advantageously employed for twisting or plying both fine and coarse yarns.
- the new device may be generally described as an upright inflow two-for-one twister. It comprises essentially a vertically disposed driven spindle, a take-up device and support platform therefor mounted on the spindle and magnetically stabilized against rotation therewith and a fiyer secured to and rotating with the spindle for causing yarn introduced into an axial passage in the lower end of the spindle and led out through an aperture in the side thereof to balloon about the take-up device before being delivered downwardly thereto.
- the fiyer is preferably a disk type fiyer and has associated therewith a Wraparound or storage device for the yarn issuing from the spindle aperture.
- a balloon confining ring or band positioned substantially at the level where the diameter of a free balloon about the take-up device would be maximum provides, with the storage device, tension control stabilization of the balloon shape.
- the above briefly described device inserts two twists into the yarn with each rotation of the spindle.
- the device When a single yarn is fed into the lower end of the spindle the device operates as a simple two-for-one twister.
- the yarns When two or more yarns are fed thereto, the yarns are twisted together and hence the device operates as a plyer twister.
- Fig. l is a side view partly in section of a two-for-one twister embodying the invention
- Fig. 2 is a horizontal sectional view of the device of Fig. 1 taken on the line 2-2 thereof
- Pig. 3 is a top plan view of the device of Fig. l
- Fig. 4 is a diagrammatic side View showing the device of Fig. 1 arranged for plying of two separately twisted single yarns.
- the new twister includes a spindle 2 which is rotatably mounted by means of upper and lower bearings 4 and 6 on a post 8 carried by a spindle rail it). Secured, as by welding, to the spindle 2 is a disk fiyer 12 with which is associated a wrap-around device 14 having an annular skirt 16.
- the post 8 has an axial passage 18 which communicates with an orifice 26 in the side wall of the spindle.
- the orifice 20 is substantially at the level of the skirt 16 of the storage device and of a yarn guide slot 22 therein.
- a support frame or platform 24 is carried by the spindie 2 above the fiyer 12 by means of a suitable bearing.
- Magnetic means as for example, a small permanent magnet 26 carried by the frame and a fixed magnet 28 supported from the rail 16 by a bracket 39, serve to prevent rotation of the frame with the spindle.
- journaled in the vertical walls 24 'of theframe is the axle of a spirally grooved traverse roll 32 of conventional construction.
- the roll 32 is driven by a belt 34 from a pulley 36 fixed to the shaft of a gear 38, gear 38 being driven by a pinion gear 40 on the upper end of the spindle 2.
- a pair of idler pulleys 42 and 44 are provided for guiding the belt 3d in its passage between the pulley 36 and roll 32.
- the side walls 24 of the frame 24 are provided with V-shaped slots 46 for reception of the ends of the axle 48 carrying a cylindrical bobbin form 49 for a package 50, the package being wound by surface engagement with the spirally grooved traverse roll 32 in conventional manner.
- the package is illustrated as being almost completely wound and therefore the axle 48 is above the bottom of the slot 46.
- a ring 52 is secured as by screws 54 to the frame 24 adjacent the top thereof to serve as an inner limit for the yarn balloon.
- An apex yarn guide 56 is supported by an arm 5 mounted on the frame in the neighborhood of the magnet 26, arm 55 being hinged to permit the guide to be retracted for removal of the package 50.
- Mounted in upwardly extending portions 66 of the side walls 24' of the frame is a yarn guide pin 62 over which the yarn Y passes from the guide 5'6 to the grooved roll 32.
- a ring or band 54 Secured to the bracket 30 at a level substantially midway between the guide 56 and the base of the frame 24 is a ring or band 54 which engages the yarn in its path from the disk fiyer 12 to the guide 56 and, together with the wrap-around device 14, insures proper stability of the balloon shape.
- Rotation of the spindle 2 causes rotation of the roll 32 and of the bobbin-axle unit, the bobbin-axle unit being rotated through surface engagement with the roll.
- the rotation of the roll 32 and form 49 causes travel of the yarn through the spindle passage and over the under surface of the flyer, up to the guide 56 and down over guide 62 to the package and rotation of the fiyer causes the yarn in its passage to guide 56 to balloon about the frame and parts carried thereby, the frame and the elements thereon being prevented from rotating as a unit by the magnetic attraction between the poles of magnets 26 and 28.
- a balloon confining ring such as ring 64
- the functioning of a balloon confining ring, such as ring 64 when used in conjunction with a wrap-around or storage disk such as device 14 is described with reference to two-for-one twisters of the outflow type.
- the twister of Figs. 1 to 3 inserts two twists into the yarn at each revolution of the spindle, one twist at exit from the spindle orifice and one at passage through the guide 56.
- the twister is particularly adapted for use in plying as it requires but relatively small gauge for a high rate of twist insertion.
- Fig. 4 the device of Figs. 1 to 3 is shown arranged for plying two yarns each separately pretwisted on twisters which may be, and preferably are, twisters of the type disclosed and claimed in the said pending applications.
- a unit of a two-deck frame is diagrammatically illustrated as including upper and lower spindle rails 76 and 78, respectively, with the spindles 3% of two outflow two-for-one twisters 82 mounted on the lower rail 78.
- Each of the twisters 82 which are preferably of the type disclosed in Serial No.
- 179,069 includes a supply of yarn 84 supported from a platform 86 rotatably mounted on the spindle 80 and magnetically stabilized against rotation therewith, suitable pretensioning means 88 axially positioned above the yarn supply, a disk flyer and storage device 90 secured to the spindle 80 beneath the platform 86 and a balloon confining ring 92.
- a yarn guide 94 suspended from the upper rail 76 at the apex of the yarn balloon formed about the supply package serves to guide the yarn to the axial passage 18 of spindle 2.
- the supply packages 84 and tension device 88 are preferably enclosed by suitable covers 96 of plastic or the like.
- the take-up unit of the plying device does not need to be enclosed as appreciable tension in the yarn between guide 56 and roll 32 (see Fig. 1) prevents -it from being carried out into the balloon path.
- a cover is omitted threading-up is simplified.
- the arrangement of Fig. 4 has a substantially greater production rate per foot of spindle rail.
- the ply twister can be designed for gauge of 8 inches, can wind a package of 1.7 lbs. of yarn between dofiing, and can operate at 10,000 R. P. M. Thus, a rate of twist insertion in the neighborhood of 30,000 twists per minute per lineal foot of rail is achieved.
- 179,069 means are disclosed for preventing continued feed of yarn through the spindle orifice after a break has occurred in the yarn balloon and for trapping the tail of yarn extending from the spindle under such circumstances.
- These means have not been illustrated herein as forming no part of the present invention but it will be understood that the spindle 2 of the ply twister, as well as the spindles of the twisters supplying yarn to be plied, could, and preferably would, be provided with such means.
- the twister of the present invention when supplied with yam from a single two-for-one twister, whether of the type of that disclosed in Serial No. 133,047 and Serial No. 176,069 or of any other type, operates together therewith as a four-for-one twister.
