7 Claims.
This invention relates to the manufacture of round-section chenille yarn from chenille yarn having radial tufts.
I An object of this invention is to provide an improvedmethod and means for curling the radially positioned threads of chenille yarn by first mechanically compacting the threads into a curled form of much smaller diameter, and then subjecting the round chenille to an ironing treat- Another object of this invention is to provide means for continuously imparting a partially compacted and spirally curled form to a chenille yarn, comprising an elongated tube having a cc-nicalinlet end and having a conical thread in said inlet end, the said elongated tube having aninner diameter corresponding to the smallest.
diameter of the conical inlet and in providing -rueans torn-eating the saidtube and meansfor rotating the heated tube.
Another object of this invention is to provide f means for frictionally restraining and tcnsioning chenillelyarn against rotation at the entrance into said conical inlet and in providing means for pullfeeding the chenille yarn at the exit end of the .said tube, the said tensioning and feeding With the above and. other objects in view, the
invention will be hereinafter more particularly described, andthe combination and arrangement of parts will be shown inthe accompanying drawing and pointed out in the claims which form part of this specification.
' Reference will now be had to the drawing, I
wherein like numerals of reference designate cor responding parts throughout the several views, in
Figure 1 treatment. I
Figure 2 is an end view of the chenille yarn after treatment, the figure be'lng on an enlarged is an end view of chenille yarn before scale. i I
Figure 3 is a side elevationof apparatus for carrying out my method of treatment of the chenille. I I
Figures is a central cross-sectional View of; the
apparatus shown in Figure 3. I
FigureS is a cross-sectional view of amodified.
a feeding movement tube having a portion of its length threaded, the thread being a continuation of the thread in the conical inlet to the tube.
In the illustrated embodiment of the invention, the numeral it indicates an elongated tube having an integral conical inlet. I I. The inlet I i has a conical thread I2 throughout its length. I
The tube ill has been rotatably mounted in ball bearings it carried in bearing supports M. A pulley it fixed to the tube It is driven by a belt It and causes rotation of the tube.
The rotatably mounted tube Ill is enclosed by a. stationary electrical heating unit I? having a l:1ighresistance wire It; An electric current passing through thehigh-resistance wire causes the wire to get hot and to heat the heating unit ii and the tube it. I
The bearing supports I4 and the heating unit Il may be secured to a base I9. Secured to the base are spaced supports 20 having eyelets 2i in alinement with the axis of the tube Ill.
Secured to the base at the outlet end of the tube i0 is a bearing. 22 having a shaft 23 rotatably mounted therein. A roller 2% has been fixed t0 the shaft 23. Supported by an extension 25 of the bearing 22 is a carrier 26 having an elongated vertical slot 2'l. A roller 28 has an integral axle 29 journalled in the slot 27 and is thus adapted for vertical motion to and from the roller 24. v
A gear Ell fixed to theshaft 23 and driven in any suitable manner in direction of the arrow,
causes rotation of the roller 24 and the superposed therethrough. I
The yarn 3! after being passed through the eye'- lets is pulled through the conical inlet I I and out of the tube l-EI and around the rollers 24 and 289 The roller 28' has considerable weight and causes a frictional drag tobe exerted on the yarn passing therebetween. When the gearilll rotates the shaft23 and the attached roller 24, a pullfeeding action takes place and the yarn is congagement with the radial threads 33 and gradually curls the said threads in spiral form and compresses them to a much smaller diameter corresponding to the internal diameter of the tube H]. The partially compacted and curled yarn in passing through the heated portion of the tube it] is ironed and assumes a permanent set and so that the chenille yarn in the said form 34 is of the same diameter throughout and has finely curled threads. 7
It is to be noted that the rotation of the threaded tube I0 must be in the direction of the,
twisting of the core 32 of the chenille yarn 3|.
The temperature of the heating unit I! is regulated to suit the particular yarn worked upon.
It is essential that the pull-feeding mechanism shall be geared to pull through the tube a length of curled chenille yarn exactly corresponding to the length of tufted chenillebeing curled and fed by the screw threaded conical inlet I I.
In accordance with the patent statutes I have described and illustrated the preferred embodiments of my invention, but it will be understood that various changes and modifications can be made'therein without departing from the spirit of the invention as defined by the appended claims.
I may utilize the modified heating or ironing tube shown in Figure 5, the said tube having an internal screw thread 35 for a portion of its length and forming a continuation of the thread in the conical inlet to the tube.
