` z claims. lol. 57-15z) *n This invention relates to the textile art, espe- .cially to anv elastic novelty yarn which is formed of separate elastic and inelastic threads, yarns, cords, or strands.
A general object of the present invention is to provide a novel type of elastic yarn, which has desirable properties, and a method of making Same.
A further object ofthe invention is to provide an elastic novelty yarn which producesv unusual effects when fabricated to article form,
The foregoing and otherobjects will be manifest from the following specification which is described with particular reference to the accompanying drawing -of whichz Figure 1 is an elevation of a slightly tensioned elastic yarn embodying the invention, which yarn is stranded out at one end to show the components thereof;
Figure 2 isan elevation of the yarn 'of Figure 1 when it is relaxed; andv Figure 3 is a diagrammatic elevation of apparatus for forming the yarn of Figure 1. lReferring in detail to the drawing, an elastic yarn I is shown, which yarn includes a rubber thread IIwhich is twisted together with a' core thread I2. A yarn I3 is loosely wrapped around the two threads II and I2 as a unit in the same direction as the twist of the threads Il and'l2'.
Note that the convolutions of the yarn I3 around n' the elastic thread are drawn into substantially abutting relation when the/yarn I0 is relaxed as the yarn I3 is wound upon the threads II and I2 when the rubber thread II is tensioned. A binder thread I4'is wrapped around the unit formed of the elastic thread II, core thread I2 and yarn I3 to 'retain vthe yarn and thread together and form a finished yarn therefrom, the binder thread being' wound in the opposite direction to the 'yarn I3, as shown.
' The binder -thread I4, the core thread I2, and the yarn I3 all may be made from cotton, wool or other suitable materials. Note that loops and/or convolutions of the yarn I3 extend radially outwardly of the elastic yarn I0 between the yarn I0 may be tensioned any desired amount,
` 'or else completely relaxed to bring such loops or convolutions of the yarn I3 into the desired relationship and vary the appearance of the yarn. In all events, the yarn ,I0 presents an attractive appearance and is adaptedto befabricatedin eitherl tensioned or relaxed'form.. Obviously the ,elasticity of the `yarn adapts it for new and desir-I l lable'uses over ordinary novelty yarns. i l
A Theyarn I0 maybe made upon apparatus including rollers 20 and 20a between which the core thread I2 and elastic thread II are drawn, the elastic thread being held under tension as the vyarn I0 is produced. The core. thread I2 is wound upon a bobbin 2'I and drawn' therefrom over a guide 22 while the elastic thread II is carried by`a flanged roll 23 which-,is supported .on
a roll- 24y driven'by a chain 25. The outer surface of the thread II carried by the roll 23 rests directly upon the roll k2,4 so that, by driving the roll 24 at a uniform speed, the elastic thread is unwrapped from the roll'23- at a uniform rate. The
elastic thread II should be placed upon the roll 23 under uniform tension to aid in removing it `therefrom. at a uniform rate.
The elastic thread and core thread arearranged in ,parallel and pass over a guide roll 26 the bobbin 30 over a guide 35 by driven rolls 33 after passing through the rolls 20 and 20a and then overa faller bar 211. The yarn I3, carried on a bobbin 30, is fed in to the elastic thread and co're .thread faster than the threads are -drawn through lthe rolls 23 and 20a and at an,
appreciably angle to their axes to facilitate wrap- Y ping it therearound. The yarn I3 is drawn from and 34. Thecomposite yarn passes through a guide 28, a ring traveler 29 ,and then is wrapped around a bobbin 3|. The elastic thread and the y core thread are twisted together and the yarn I3 'is twisted therearound by rotating the bobbin through a driven pulley 32.l The ring traveler 29 is slidably mounted for rotationon a vertically movable bar 36 so that the ring traveler can move lup and down withrelation to the bobbin 3l to aid in distributing the yarn thereover.
The yarn III is completed by passing the unit formed from the' core 'thread I2, elastic threadJ II and yarn I3 through the apparatus a second time. Il, Vthe second step of forming the yarn I0, the bbin 3| is substituted for the bobbin 2I and the yarn thereon is led therefrom through the rolls 20 and 20a and over the guide 26 and failer bar 21, after which the binder thread vIl n the convolutions of the binder thread Il and that is led to the yarn in a manner similar to that in which the yarn I3 is fed. The binder thread I4 is twisted. onto the Yunit formed by the elastic thread, core .thread'and yarn by leading the 'n composite yarn through the guide 28 and 'ring' traveler' 29 to a rotating bobbin substituted for the bobbin 3i. Of course, the bobbin. in this case will be driven in the opposite direction from the bobbin 3| to wind the binder thread oppositely to the yarn I 3.
It will be'appreclated that the yarn lo may be produced with the elastic thread I I under any desired tension. Usually both the core thread I2 and the binder thread I4 are wrapped around the elastic thread II when it is under substantially the same tension and about equal lengths of the binder and the core thread are so vpositioned whereby both threads limit the extensibility of the yarn I0.
It will be seen that novel and unusual effects can be produced by coloring any of the threads I2 or I4, or, especially, the yarn I3, which color- L ing may vary in different sections of the thread or yarn colored.
In some cases, it may be desirable to feed the unit formed ofthe elastic thread II, core thread I2, and yarn I3 to the rolls 20 and 20a by a positive feed when completing the yarn I0. That is,
y the bobbin 3| could be provided with end flanges.
in, it will be apparent that modification thereof 'may he made without departing from the scope of the invention as defined in the appended claims.
What is claimed is:
1. 'An elastic novelty yarn comprising an e1astic thread, a core thread wrapped around said elastic thread to form a unit which lies along the axis of the novelty yarn when it is tensioned, a yarn loosely wrapped around said unit in a direction similarto the twist thereof to form a plurality of loose closely adjacent convolutions therearound when the novelty yarn is relaxed,
and a binder thread wrapped around the unit formed of said elastic thread and said yarn in the direction' opposite to the direction inwhich said yarn is wrapped around said elastic thread to form elastic novelty yarn. w
2. An elastic novelty yarn comprising an elastic thread llying along the axis of the novelty yar-n, a yarn loosely wrapped around said elastic thread to form a plurality 'of loose closely adjacent convolutions therearound when the novelty yarn is relaxed, and abinder thread wrapped around the unit formed of said elastic thread and said yarn in the direction opposite to the direction in which said yarn is wrapped around said elastic core thread to form elastic novelty yarn. r STERLING W.
