Definitions

  • a further object of the present invention is to provide apparatus for producing commercially acceptable natural fiber yarns of the textured types described characterized by their lengthwise uniformity and having a uniform set in which the individual fibers of the yarn exhibit a permanent inherent tendency to assume a formation conforming to the configuration of the permanent set of the fibers.
  • An additional object of the present invention is to provide apparatus for producing textured yarns from natural fibers wherein said fibers are impregnated during their continuous travel with a heat-reactive material whereafter said fibers are twisted and passed through a zone of relatively high temperature for rapid removal of the excess particles of said material, the fibers thereafter passing through a zone of relatively lower temperature while in said twisted state to permanently set the twisted fibers in a twisted or deformed configuration.

  • FIG. 3 is an enlarged fragmentary view of a portion of the false twist spindle and showing the lint removal means therefor;
  • FIG. 4 is a sectional view of the heater of the present invention taken along lines IVIV of FIG. 1.
  • the preferred apparatus for carryingout the present invention comprises a multistation machine, each station including a separate yarn supply, afurnishing roll, a bath into which the yarn is immersed, spaced tension devices for applying a preselected tension to the yarn after immersion, a two-stage heating zone and a false twist spindle for the tensioned yarn intermediate the spaced tension'devices, feed rolls and a take-up.
  • the yarn supplies are disposed in rows along the apparatus, and the drives for the respective furnishing rolls, false twist spindles and the take-ups are coordinated by conventional drive means (not shown) to correlate the linear speed of travel of the yarn with the rotational speed of the false twist spindle to insert the desired twist into the yarn.
  • the heated zones are likewise correlated to the linear travel of the yarn to supply sufficient heat thereto United States Patent 0 3,257,7% Patented June 28, 1966 at a first zone to vaporize or burn off any excess of material received by the yarn from the bath and, similarly, to supply sufiicient heat at a second zone to effect yarn setting in a twisted state.
  • the present invention has particular utility in practicing the methods disclosed in commonly assigned U.S. patent application of Fred B. Shippee, et al., Serial No. 320,030, filed October 30, 1963.
  • the apparatus is supported on a framework extending upwardly from a base 10 resting on the floor.
  • An upright standard 12 is affixed at its lower end in base 10, this standard serving as mount for certain of the instrumentalities of the present invention. It will, of course, be appreciated that standards of the type depicted herein will be positioned at spaced intervals along the machine, each standard being arranged in a base similar to base 10. These additional standards act as further supporting members for the multistation machine.
  • T he central region of standard 12 has a horizontal bracket 13 clamped thereto. Further, the upper end of standard 12 has another relatively heavy horizontal bracket 14 affixed thereto.
  • Bracket 14 in turn, supports a yarn creel constituted as an upright rod 16 having spaced apart horizontally extending bars 18 and 20, which run lengthwise'of the machine, attached thereto.
  • Each of the bars has a plurality of spaced pins 22 attached thereto, each pin providing the support for a supply package P of natural fiber yarn Y such as cotton, linen, wool or the like.
  • a supply package P of natural fiber yarn Y such as cotton, linen, wool or the like.
  • each of the packages P is disposed in generally a horizontal plane for over-end delivery of the yarn Y therefrom.
  • tension device 24 Upon withdrawal from its package P each supply yarn Y is conducted through a snubber-type tension device 24.
  • This tension device is aifixed to a rigid rod 26 in a suitable notch of an upright member 28 which is carried on the outer end of an arm 29. The distal or inner end of arm 29 is firmly bracketed to rod 16.
  • tension device 24 comprises a plurality of staggered fingers presenting a tortuous course to the yarn passing therethrough. Therefore, by virtue of the drag exerted by tension device 24 theyarn on package P is constrained from inadvertent removal as might otherwise occur, for example, by the inherent weight of the yarn strand suspended from the tension device.
  • each furnishing roll is provided with an annulus 36' of frictional material, such as rubber, against which the yarn is caused to bear.
  • Furnishing roll 36 is operated at a constant speed and acts to assist in presenting the yarn downstream, that is to say, beyond the furnishing roll in a condition of little or no tension in the yarn.
  • the roll plays only a very small role in furnishing the yarn therebeyond.
  • this condition causes the yarn to be drawn increasingly tighter onto the furnishing roll whereupon this roll is operative to advance the yarn.
  • furnishing roll 36 is rotated at a surface speed in excess of the normal rate of flow of the yarn therepast so that it can, in effect, overfeed the yarn beyond said furnishing roll in a substantially relaxed state.
  • Centering guide 35 serves to conduct the yarn onto the annulus of the furnishing roll.
  • the yarn is directed through loops at the opposite upright legs of yarn guide 46 by means of which the yarn is caused to pass in a path traversing substantially the width of the trough below the normal level of the bath to insure immersion of the strand and consequential impregnation thereof with the treating materials.
  • this yarn guide may be rocked as by means of its handle portion 46 clockwise, see FIG. 1, out of the bath and thereupon re-entered into the bottom of trough 44.
  • This arrangement is particularly advantageous when threading up the machine.
  • the yarn After impregnation in trough 44 the yarn is passed through an adjustable tension 50 of any well known type capable of imparting a predetermined amount of tension uniformly to the yarn, aflixed on the upper surface of a forwardly inclined flat plate or panel 52 running lengthwise of the machine.
  • the inner end of this panel is folded to form an elongated basin-like receptacle at 54, the function of which is to capture the excess treating material expelled from the yarn as it passes along its upcentralize the yarn path of yarn Y through said tension.
  • Heater 60 includes a tube 62 having a narrow longitudinal slot extending along the full length of the tube for the reception of a strand of yarn.
  • the lower section of tube 62 is heated by a heating plate 63 of a well known type.
  • the upper section of tube 62 is heated by a similar but independent heating plate 64.
  • a thick wall of thermal insulation 66 such as fiber glass or the like is employed to encase substantially all of the heating plates 63 and 64, the forward portions of the two heating plates, of course, being in contact with tube 62.
  • Electrical heating elements 67 and 68 which are energized by electrical conductors (not shown) are connected to heater plates 63, 64 and are covered by insulation 66 and are connected to a source of electric current. As is apparent in FIG. 1 heating elements 67 provide the heat source for plate 63 and, similarly, heating elements 68 heat plate 64.
  • heating plate 63 contacts but a minor portion of the length of tube 62 at the lower region thereof, the major, upper part of the tube being heated by heating plate 64.
  • the lower section of tube 62 is heated to a temperature in the order of approximately 500 F. to about 900 F. by heating plate 63 depending on the type of yarn being processed, the amount of treating material impregnated into the yarn, and the additional consideration of the speed at which the yarn is being advanced through the apparatus.
  • the upper part of tube 62 is similarly heated by heating plate 64 to a temperature of between 450 F. and 700 F.
  • the particular temperature required within the stated range will depend on the type of yarn being processed correlated with its rate of advancement, the heavy count yarns requiring proportionately more heat than yarns of correspondingly lighter counts. Moreover, it will also be appreciated that temperatures must be increased in the heating zone as the rate of yarn advancement through the apparatus is increased.
  • Separate heating plates 63, 64 are employed because it has been found that the lower portionof tube 62 must be heated to a temperature sufficiently high to vaporize or burn off any excess of the treating materials which may be discharged from the yarn by centrifugal force. If this is not done, the excess of treating material discharged from the yarn soon builds up on the interior surface of tube 62 to the extent that practical operating efficiency of the apparatus is substantially reduced.
  • the upper portion of tube 62 serves as a heating zone to effect the chemical reactions between the molecules of the yarn and the treating solution as described in the prior mentioned U.S. patent application 320,030.
  • a yarn guide 69 attached to the top of the heating device and serving to direct the yarn leaving the heating device to a false twist spindle 70 of the high speed type capable of operating with speeds up to 180,000 rpm.
  • the false twist spindle may be of the conventional type well known in the art employing an endless driving belt 72, hearing against the blade 76 of the spindle and thereby driving it.
  • the driving belt is guided by spaced pulleys, one of which is shown at 74.
  • the spindle is supported on a swing arm 78 so that the spindle may be swung from the operative position against belt 72 as shown in FIG. 1 to an inoperative position rocked away from the driving belt.

  • the resilient roller 80' is rotatably supported on a heavy, rigid arm 82 mounted in position on a rod 84, the resilient roller bearing on companion shaft 80 under the weight of arm 82 so that the portion of the roller which is in contact with the shaft 80 is pressed tightly and steadily thereagainst to actually wrap itself partially around the periphery of the roller and thereby afford an area contact between these two elements comprising the feed rolls.
  • the yarn Y is guided by guide 81 to the respective take-up rolls and 92 for the left and right hand yarns of the particular processing station.
  • Guide 81 also serves to maintain the yarn on the feed rolls during starting of the machine.
  • the take-up rolls are positioned in front of the machine respectively above and below top feed rolls 80, 80' thereby avoiding inter ference of the operation of one take-up by the other.
  • a guide rod 94 is positioned upstream of each of the take-up rolls 90, 92.
  • the yarn runs against and is guided by said guide rods 94 in its passage to the respective take-up rolls.
  • a reciprocating traverse guide 96 affixed on an elongated traverse bar 98 engages the yarn passing over the guide rod 94 to position it on one of the respective take-up rolls 90 and 92 so as to provide a level wind thereon.
  • the traverse bar 98 may be moved to and fro by any conventional means such as .a traversing cam not illustrated herein.
  • the takeaup rolls 90, 92 are driven by surface contact from drive rolls 102, 103, respectively.

  • Take-up rolls 90, 92 are supported for rockable movement through a limited are, respectively, on rigid arms 106 and 107.
  • arm 106 is rotatably supported on one end of a shaft 108, and, similarly arm 107 is carried on shaft 109.
  • This movement permits ready doffing and donning of packages on the take-ups as well as to afford movement of the packages as they increase in diameter.
  • the opposing ends of the shaft 100 are secured in a bracket 110 extending forwardly for this purpose from its anchoring point on standard 12.
  • a similar bracket 111 is provided for mounting haft 109.
  • Handles 112 and 113 are provided for rocking arms 106,
  • a segment 114 fixed to shaft 108 provides a guide and stop means for the motion of arm 106.
  • a pair of spaced, parallel ducts, 122 and 124 are connected to the bracket 13 and a web 14' depending from bracket 14 of the machine.
  • Said ducts 122, 124 extend the full length of the machine and are joined with a suitable suction source (not illustrated herein).
  • duct 124 lies in a plane below duct 122.
  • Said duct 124 is formed as an inverted U-shaped member having its normally open bottom wall enclosed by a plate 128. This plate, in turn, has a series of apertures 130 therethrough along the medial line thereof. As seen in FIG.
  • bafiie 132 extends forwardly over the major width of heating device 60. This baffle 132 projects rearwardly on a slight upward incline, see FIG. 1, and is connected at its rearward longitudinal edge to the forward edge of slot 126. In this fashion fumes which float upwardly from heater device 60 are directed to suction duct 124 to be sucked inwardly and vented off through said duct.
  • the opposing duct 122 is disposed rearwardly of and in horizontal alignment with the upper section of false twist spindle 70.

  • An elongated flexible belt 136 is positioned in opposed track 137, 138 to lay closely against the wall of ducts 122 having the aforementioned ports 134.
  • Belt 136 is engaged on pulleys (not illustrated) at each end of the machine, at least one of these pulleys being suitably driven to move the belt longitudinally of duct 122.
  • Said belt 136 has one or more openings through its side as at 140 of generally the same area as ports 134 and arranged to move into register with these ports as belt 136 is moved along the length of the duct.
  • a suction is created in the zone of the head of spindle 70 to clear away lint, fly and other particles which may be undesirably deposited about the spindle as the cellulosic fiber yarn is twisted.

  • the yarn is drawn off of package P by feed rolls 80, 80 and guided down to furnishing roll 36 as already described.
  • Furnishing roll 36 assists in overfeeding the yarn to the bath in trough 44, that is to say, the yarn is advanced from the furnishing roll to the bath in a relaxed state under minimum tension. Thereby, the relaxed yarn is free to pick up the maximum amount of treating materials. In consequence thereof, the yarn is thoroughly impregnated with the treating material. In this condition the yarn is passed through gate tension where some of the treating solution is pressed out of the yarn to flow along panel 52 back into the bath.
  • tension 50 establishes a predetermined tension in the yarn in the zone between said tension and spindle so that, as the yarn is twisted by false twist spindle 70, and the twist runs back along the strand through the zone of heating device 60, the yarn will be uniformly twisted at a desired uniform tension.
  • the movement of the yarn is continuous and that the yarn moves at a constant selected linear speed from the supply package P to said feed rolls 80, under the influence of top feed rools 80, 80'.
  • the yarn is passed from tension 50 to the bottom guide 58, through tube 62, through guide 69 to spindle 70.
