Description:

My invention relates to a novelty yarn and a novel process of making the same and more particularly my invention relates to a yarn comprising a multiplicity of decorative threads twisted over a core in such a fashion that each decorative thread forms a multiplicity of adjacent knops, the multiplicity of decorative threads forming a distinct set of knops with a repeat pattern along said yarn.

The most important considerations in the manufacture of the novelty yarn are to obtain distinct novelty effects and at the same time to get a reasonably light yarn so that it is not too costly and so that it can be used in a variety of fabrics.

In the novelty yarn of my present invention I obtain variegated effects in the form of a repeat pattern which is made up of a multiplicity of knops, as for example two adjacent knops, formed from a single decorative thread and a multiplicity of decorative threads, such as for example five, being used to form a series of 10 knops for each repeat pattern, the ten knops being formed two each from the five different decorative threads.

The method of making my novelty yarn is such that an extremely light decorative yarn is obtained especially with regard to the variegated decorative effect obtained by the use of a multiplicity of decorative threads.

It is the object of my invention to provide a novelty yarn having variegated effects in a repeat pattern.

It is a further object of my invention to provide a novelty yarn made up of a series of different and distinct decorative threads.

It is a further object of my invention to provide a novelty yarn which has as its primarily decorative motif a series of a plurality of knops of a multiplicity of decorative threads.

It is a further object of my invention to provide a novel method of twisting about a core a plurality of decorative threads so that each decorative thread forms two adjacent knops, the decorative thread being then twisted about the yarn until the knop pattern is repeated.

These and further objects of my present in vention will be apparent from a consideratior of the drawing and the specific description there of which here follows: Figure 1 is a perspective of the novelty yar of my invention.

Figure 2 is a side view of the apparatus em ployed in forming the novelty yarn of my in vention.

Figure 3 is a front view of the apparatus which illustrates the method of forming the novelty yarn of my invention.

Figure 4 is a detail showing the stage in the j process of the manufacture of my novelty yarn next after that shown in Figure 2.

Referring now more specifically to the drawing, in Figure 1 I show a novelty yarn generally denoted as 10, which comprises two knops II and u 12 formed from a thread of decorative material 13 which may, for example, be rayon. Immediately adjacent the two knops 11 and 12 of decorative material 13, are knops 15 and 16 formed from a second decorative material 11, 1 which knops may be, for example, of worsted.

Knops 19 and 20 formed from decorative material 21 are positioned adjacent knops 15 and 16. After knops 19 and 20 come knops 22 and 23 which are formed from still another thread of decorative material 24 which may be, for example, worsted. Seen at the extreme right of Figure 1 are knops 26 and 27 formed from a thread of decorative material 28 which may be, for example, worsted.

The knops aforementioned are twisted over a suitable core which, as shown, is made up of two threads 42 and 43, of, for example, cotton or the like. The novelty yarn is bound back with the binder 31.

The various decorative threads employed preferably are distinct and different from one another and particularly the respective sets of adjacent knops, such as knops 15 and 16 are distinct in appearance and in contrast with knops 19 and 20. It. will be recognized that the knops II and 12 are similar to one another and are formed from the same thread of decorative material 3, and similarly knops 15 and 16 are formed from the same thread of decorative material 17.

The threads of decorative material employed may be rayon, worsted, wool, silk, mohair or any suitable decorative material, and the pattern in which five different decorative threads S45 are employed as shown in Figure 1 is repeated along the yarn as will be more particularly pointed out hereinafter.

In Figure 2 I have shown an apparatus comprising suitably mounted reels 40 and 41 from which are drawn core threads 42 and 43. The core threads 42 and 43 are drawn between idler roll 45 and the driven roll 46. Roll 46 has a sprocket 41 shown in dotted line mounted on one end thereof and this sprocket 41 is driven by pins 48, 49 etc. mounted on the driven whee 50.

By means of this driven pin and idler sprockel arrangement, an intermittent motion is effectec in the roll 46. Core 42, 43 moves downwardly and about this core are twisted the decorative threads 13, 17, 21, 24 and 28 which are drawn from suitable mounted rols 57, 58, 59, 60 and 61.

The decorative threads which, as above, may be threads of rayon, worsted, wool, silk, mohair or any suitable decorative material are drawn by the continuously moving set of rolls made up of idler roll 64 and driven roll 65. The threads 13, 17, 21, 24 and 28 of decorative material pass over faller bars 70, 71, 72, 73 and 74, respectively, and form knops over the core 42, 43. The knopped yarn 10 which is formed then passes through the guide 76 and through the traveller 77 and thence is wrapped around the driven bobbin 78.

The method of my invention is as follows: The core 42, 43 is moved downwardly in intermittent motion by the pins 49 on the wheel 50 so that the core stops in front of the faller bars 70-74 and after a predetermined period during which knops 11 , 15, 19, 22 and 26 are formed on the core by the threads of decorative material 13, 17, 21, 24 and 28, the core: again moves down a short space at which time, as shown more particularly in Figure 4, the knops 12, 16,20, 23 and 27 are formed adjacent to the first formed knops, so that a pattern of ten knops, each two of which are similar and formed from the same decorative thread, are formed over the core 42, 43. The two adjacent knops being of the same e decorative material and therefore the same color and appearance form a novely yarn having a multicolor effect in which, for example, areas of blue, gold, red, green and white forming a repeat pattern, occur in regular sequence.

After the two knops such as II and 12 are 4 formed from the thread of decorative material 13, and similarly the other knops are formed from other threads of decorative material, the pins 48 48 etc. by reason of the rotation of the wheel 50 engage the sprocket 47 and turn the roll 46 for 4 a sufficient length of time to move the knopped yarn down completely beyond the faller bars and to bring a new portion of th e core 42-43 into position by the faller bars 70-74 so that another set of knops can be formed on that portion of 5( the yarn.

By means of the process above set forth, I employ a minimum of decorative thread material and the decorative thread may be light in weight because of the combination of threads involved 56 so that I obtain a distinctive novelty yarn which is extremely light in weight, reeling as for example in the case of the use of four decorative threads of worsted and one decorative thread of rayon, about 962 yards of novelty yarn to the pound. It will be realized that this is light weight novelty yarn and hence of definite value.

It is to be understood that it is within the purview of my invention to form a multiplicity of adjacent knops of the same decorative material. That is, in lieu of the two knops of the same decl orative material, as shown in the present specific example of my invention, I may employ three, or four or even more adjacent knops of the 5 same material. I may also employ more or less than the five decorative threads shown and I intend to include such variants in the decorative threads employed in the present invention.

The sets of adjacent knops formed of the same decorative thread, and therefore presenting the same appearance characteristics, make for a general color patch appearance in the novelty yarn.

Certain variations in the method of manufacture will be apparent to those skilled in the art. It is my intention, therefore, not to be limited by the particular examples of the yarn and method of making the same which I have set forth by way of specific example of my invention, but only by the claims hereto appended.

I claim: 1. A novelty yarn comprising a multiplicity of threads of decorative material twisted about each other, a multiplicity of knops formed from each thread of decorative material, at least two knops formed from the same decorative material being positioned adjacent one another.

2. A novelty yarn comprising a multiplicity of threads of decorative material twisted about a core, and a multiplicity of knops formed from each thread of decorative material, at least two knops formed from the same decorative material being positioned adjacent one another.

3. A novelty yarn comprising a multiplicity of threads of decorative material twisted about a core, at least two adjacent knops being formed in said yarnfrom each thread of decorative material, said yarn being characterized therefore by a multiplicity of sets of knops of decorative material along its length.

o 4.. A noveltyyarn comprising a multiplicity of threads of decorative material twisted about a core, at least two adjacent knops being formed in said yarn from each thread of, decorative material, said yarn being characterized therefore r, by a multiplicity of sets of knops of decorative material along its length, each set of knops contrasting in appearance with the next adjacent set of knops. , 5. The method of:forming a novelty knop yarn. Scomprising advancing a core, stopping said core, twisting a multiplicity of spaced threads of decorative material about said core to form knops thereon, advancing said core again a relatively: short distance, again stopping said core, twisting S the same multiplicity of spaced threads of decorative material.about said core to form a second set of knops about said core adjacent ,to but spaced from said first set of knops, said second set of knops being formed from the same threads of decorative material respectively as said first set of knops, and moving said core a relatively longer distance so that said multiplicity of spaced threads of decorative material can form sets of knops about another area of said core.
