Definitions

  • the present variable feed means operates to produce variations in the bulkiness along the length of fluid jet textured yarns.
  • the apparatus includes spaced apart first and second yarn feed rolls positioned between the yarn supply source and the fluid jet with the first yarn feed roll being operable to feed the yarn at a relatively slow speed and the second yarn feed roll being operable to feed the yarn at a second relatively fast speed.
  • Feed control means is provided for alternately moving the yarn into driving engagement with the first and second feed rolls to thereby vary the speed at which the yarn is fed to the jet and to produce variations in the bulkiness along the length of the yarn.
  • This invention relates generally to a variable feed device for a jet texturing apparatus for producing varia' tions in the bulkiness along the length of fluid jet textured yarns.
  • the present variable feed includes spaced apart first and second yarn feed rolls positioned between the yarn supply source and the fluid jet with the first feed roll being operable to feed the yarn to the jet at a first relatively slow speed and the secondyarn feed roll being operable to feed the yarn to the jet at a second relatively fast speed.
  • Feed control means is provided for al ternately moving the yarn into driving engagement with the first and second feed rolls to thereby vary the speed at which the yarn is fed to the jet and to produce variations in the bulkiness along the length of the yarn.
  • the difference in relative speeds of the first and second feed rolls may be varied as desired to produce any desired degree of intermittent bulkiness or thick and thin places along the length of the yarn and to form neps or slubs in the yarn at variously spaced intervals.
  • FIG. 1 is a somewhat schematic isometric view of one I station of a jet texturing apparatus and illustrating the variable feed means of the present invention associated therewith;
  • FIG. 2 is an enlarged side elevational view of the variable feed means of the present invention; with the cover housing removed;
  • FIG. 3 is a plan view of the variable feed means shown in FIG. 2;
  • FIG. 4 is a vertical sectional view taken along line 4-4 in FIG. 2;
  • FIG. 5 is an end elevation view looking at the righthand end of FIG. 2 and with parts in section;
  • FIG. 6 is a vertical sectional view taken along line 6-6 in FIG. 2.
  • the variable feed means of the present invention is illustrated in FIG. 1 as being associated with a particular type of jet texturing apparatus, however, it is to be understood that the variable feed means may be associated with other types of jet texturing devices and machines.
  • the jet texturing apparatus includes a yarn supply source in the form of a yarn supply package or bobbin 10 from which the yarn Y is withdrawn.
  • the yarn Y passes through a conventional type of tension device in the form of a tension disc 11, passes through the variable feed means of the present invention and in a manner to be presently described, and is fed thereby into a fluid jet 12.
  • the yarn Y passes through a tension device in the form of a tension fork 14, passes over a roll where a suitable lubricant is applied to the yarn.
  • the yarn Y is then wound onto a suitable take-up package, indicated at 16., and'is guided onto the yarn take-up package 16 by a yarn traversing guide 17.
  • the yarn take-up package 16 is rotated by a suitable drive roll 18.
  • the variable feed means of the present invention includes a first yarn feed roll 20 and a second yarn feed roll 21, both of which are positioned between the yarn supply package 10 and the jet 12.
  • the yarn Y is directed above the upper peripheral surface of feed roll 20 by suitable yarn guide means in the form of yarn guide eye 22 and a guide roller 23 supported on the outer end of a spring wire 24.
  • the inner end of the spring wire 24 is fixed on a bracket 25 which supports a separator roll 26.
  • the resilientlysupported guide roller 23 may be referred to as a yarn inventory roller as it is lowered to immediately provide yarn when the yarn is driven at the fast speed by the feed roll 21, in a manner to be presently described.
  • Thefirst feed roll 20 is fixed on the end of a drive shaft27 which is rotated at a relatively slow speed to feed the yarn to the jet 12 at a first relatively slow speed when the yarn is drivinglyengaged by the roll 20.
  • the second yarn feed roll 21 is operable to feed the yarn to the jet 12 at a second relatively fast speed and in a manner to be presently described.
  • the feed roll 21 may be driven at different peripheral speeds by means of a drive belt 28, which may engage different diameters of a drive pulley 29 fixed on the feed roll 21.
  • the feed roll 21 and pulley 29 are-fixed on a shaft 30 (FIG. 5) suitably supported for rotation in the lower end of a support plate 31.
  • the upper end of the plate 31 is clamped in position on a non-rotating collar 32 by a screw 33.
  • the drive belt 28 is driven by a pulley 34 fixed on a drive shaft 35 (FIG. 1).
  • the differential in speed between the feed roll 20 and the feed roll 21 may be varied by changing the position of the drive belt 28 on the pulley 29. Also, the speed differential may be changed by changing the relative speeds of the drive shafts 27 and 35. Thus, the variation in speed of the yarn feed rolls 20, 21 may be varied as desired. It has been found that a satisfactory slub yarn can be produced by driving the first feed roll 20 at a speed to move the yarn at a rate of 100 yards per minute while the second feed roll 21 is rotated at a speed sufficient to move the yarn at a speed of 500 yards per minute.
  • Feed control means is provided for alternately moving the yarn into driving engagement with the first and second feed rolls 20, 21 to thereby vary the speed at which the yarn is fed to the jet 12 and to produce variations in the bulkiness along the length of the yarn.
  • the feed control means includes actuator means in the form of a rocker bracket 41 which is pivotally supported intermediate its ends as at 42 on the medial portion of a support arm 43.
  • the l support arm 43 is fixed at one end to the support plate 31 and its other end supports a bracket 44.
  • First and second idler rolls 45, 46 are rotatably supported on the respective upper and lower ends of the rocker bracket 41.
  • the rocker bracket 41 is normally urged to the position shown in FIG. 2 by resilient means in the form of a torsion spring 50, one end of which bears against the rocker bracket 41.
  • the medial portion of the spring 50 extends around a screw 51 and the other end is supported against a pin 52.
  • the rocker bracket 41 is normally urged'in a clockwise direction in FIG. 2 so that the idler roller 45 engages the yarn Y and moves the same into driving engagement with the first feed roll 20 so that the yarn is fed to the jet 12 at the relatively slow rate and the jet 12 thus imparts a predetermined bulkiness to the yarn.
  • the idler roller 46 is normally maintained out of engagement with the feed roll 21 and the yarn Y.
  • a solenoid 55 is adjustably connected to the upper end of the rocker bracket 41 and an electric wire 56 connects the solenoid 55 to a suitable program device, indicated at 57 in FIG. 1.
  • the program device 57 operates at the desired intervals to energize the solenoid 55 and move the rocker bracket 41 in a counterclockwise direction so that the idler roller 46 engages and moves the yarn Y into driven engagement with the lower feed roll 21 to drive the yarn at the faster rate.
  • the yarn is driven by the fast feed roll 21 for a very short time and the spring 50 then moves the rocker bracket 41 so that the yarn Y is then fed to the jet 12 by the first feed roll 20 and at the relatively slow speed.
  • the spacing between the neps or slubs may be varied as desired and the length of the slubs may be controlled as desired.
  • the length of the slubs may be very short and they may be formed very close together.
  • the solenoid 55 is supported for longitudinal adjustment on the upper end of the bracket 44 by means of a base 60 to which the solenoid 55 is fixed.
  • the lower end of the base 60 is supported for sliding adjustment in a groove in the upper end of the bracket 44 and is held in adjusted position by set screws 61.
  • the position of the solenoid may be adjusted by a screw 62 extending through the upper portion of the bracket 44 (FIG. 2). If desired, a
  • cover housing 63 (FIG. 1) may be provided to extend over and protect the solenoid 55.
  • the relative speed between the first and second feed rolls 20, 21 may be varied as desired.
  • This type of yarn would thus have no texturing in certain sections which are interrupted by sections of textured yarn.
  • yarn Y it may be desirable, in certain cases, to feed one or more additional yarns with the yarn Y.
  • core yarn it is the general practice to feed two or more yarns to the jet while feeding the core yarn at a slower rate than the effect yarn.
  • effect yarn is textured by the air jet and entangled with the core yarn to produce the desired type of novelty effect.
  • the core yarn as indicated at Y in FIG. 1, is withdrawn from a separate supply package and is passed around only the first feed roll and the separator roll 26 before it passes into the jet 12.
  • This core yarn will thus be fed at a constant rate to be textured to the desired degree throughout its length and will be devoid of neps or slubs.
  • the additional or effect yarn Y follows the path shown in FIG. 1 and the idler roller 46 may be maintained against the yarn and the fast feed roll 21 so that it is constantly fed at a faster rate than the core yarn;
  • the effect yarn Y may be alternately fed at fast and slow rates while the core yarn Y is fed at a constant slow rate. In either case, both the core and effect yarns will leave the jet 12 together and will be wound onto the take-up package 16.
  • an apparatus for producing variations in the bulkiness along the length of fluid jet textured yarn comprising a yarn supply source, a fluid jet spaced from said supply source, and yarn take-up means for collecting the textured yarn; the combina tion therewith of a. a first yarn feed roll positioned between said yarn supply source and said fluid jet and being operable to feed the yarn to said jet at a first relatively slow speed,
  • a second yarn feed roll spaced from said first yarn feed roll and positioned between said yarn supply source and said fluid jet, said second yarn feed roll being operable to feed the yarn to said jet at a second relatively fast speed
  • first and second idler rolls supported on said opposed ends of said rocker bracket, said first and second idler rolls being axially aligned with said corresponding first and second yarn feed rolls and with the spacing between the rotational centers of said idler rolls being the same as the spacing between the rotational centers of said yarn feed rolls, and
  • actuator means for moving said rocker bracket to selectively move said first and second idler rolls into engagement with the yarn to press the same directly into driving engagement with the corresponding feed roll and to thereby vary the speed at which the yarn is fed to said jet so as to produce sharp variations in the bulkiness along the length of
