machine for carrying out my process of mak ing such yarns.
A core yarn comprises a core which usually consists. of a spun or twisted, substantially finished yarn of smaller size than'the complete core yarn, and arelatively thick cover or exterior which'more or less envelops the core. Where the cover is relativelythin, it is sometimes called a covered yarn.
The exterior has been made of undrawn,
untwi-sted fiber such as the film from a card,-
- it has been made of sliver, of spun or twisted yarn, and of a ribbon of filaments, such as of silk or artificial silk. v The exterior may-be twined or wound around the core in which case it will be of greater length than the core. They may be .twisted together in which case they are.
the core, to a' great degree, sinks in .out of v sight, it shows in spots and of course is not in the axial center of the finished yarn. To clearly understand my invention, it is necessaryto have clearly in mind the meaning of the terms used, and I therefore now state that the lap or sheet of fiber which is fedto a card, emerges as a film. This film, as on a woolen card, may be divided into roping or'sliver, or it may, without being divided, be condensed into a sliver. case, the sliver has no twist, its fibers are not parallel, and it is uneven. This sliver is' doubled and drawn an finally given a slight twist by suitable machinery when it becomes slubbing and roving. Roving is more even and its fibers are more parallel than is the case with a film, or sliver.
Such roving may be twisted into yarn without further drawing, or it may be'spun on suitable spinning-machinery whereby it is drawn out and then revolved about its longitudinal axis to form spun yarn.
a use as an exterior, a fiber which is so short In either The'principal purposes of my invention are to utilize well known machines Without complicatedattachments, and their products, to produce, by unskilled labor,- as cheaply as possible, a stronger core yarn which is uni-; formly even, in which the core is at the axial center and is not spiraled, and in which the exterior and core are so spun together that each helps to strengthen the other.
With my inventlon, T can use unskilled labox, and economize floor space by" using compact machines, such as ring spinning frames of high relative production.
Another purpose of my invention is to r that as a sliver or roving, it ,will not support its own weight. except when in very short lengths or of very large size. It is especially useful for short'china cotton, but I may use a fiber of long staple such as cotton, wool, jute or other similar material.
l[ have discovered that where the film or sliver from a card is rubbed onto a core, so as to surround it, and the product is wound onto a spool, the core will separate from its coveringin spots-and will also cut into the inside coils so that it will not unwind.
T have also discovered that if the cover and core are run together any distance without or before they are revolved, they will sep-.
arate and the resulting yarn will beuneven,
but that if the cover consists of roving which is flattened out by pressure devices, preferably rolls, and the core yarn is so guided as to engage it at a substantially laterally central position in the outside of the roving as both pass through such devices, the core is forced into the cover and if both are at once revolved as they leave such devices, a spun core yarn of the character described is produced. .1
In such core yarn,- the roving is wrapped. or spun around the-core, not twisted nor wound thereon, and-the whole mass is so homogeneous, that it all breaks together instead of the core breaking' first when put under a strain. F v 1 With my invention, ll use roving which has been doubled and drawn to inake it even and its fibers parallel. This is wound as usual upon bobbins, which are revolubly mounted. ina creel so as to be unwound by/ the pull of the roving as it passes through the drawing rolls. I prefer to pass this rov ing through a plurality of sets of drawing rolls, the speed of which can be varied, whereby the amount of cover can be regulated.
traversing type, and of-the special form suitable guiding devices. A
I use a guide or guides, preferably of the shown, to so guide the yarn as to unite it with, preferably the center of, the roving as it enters between the delivery'rolls, and as a means for revolving the yarn and roving as they leave the delivery rolls, I use the well known ring and traveler of the ring spinning frame.
I can .use my invention with a ring spinning frame as described, with a roving frame, intermediate, fly frame or a cotton mule, or with. any spinning machine as distinguished from a twister, by employing In the drawings 1 show my invention ap plied to a well knownform of ring spinning frame. 7
'fview of part of-a ring spinning frame show- -In the drawings Figure'l is an elevation showing part of a ring spinning frame from the side. Fig. 2 is a sectional side elevation showing the details of the drawing rolls and adjacent parts, together with one form of traversing guide. .Fig. 3 is a back elevation ofsuchguide. Fig. yis aside elevation of another form of guide. f Fig. 5 is a front ing the roving from the bobbins, yarn spools, and spindles. Fig. .6 is'a front elevation of part of a ring spinning frame -A representsa two storied creel upon the upper part of which are mounted the rovbobbins 10 in staggered relation infa well known manner, whereby .each is myolub le by the pull of its roving as 11, which,"
showing'the-guide eyes, drawing rolls and spindles in the relation in which they are on, some types of machines. Y
" passes vover a guide .rail 12 thence dowm through-traversing guideB, and through thedrawling rolls 20, 21, 22, 23, -24, 25,.jasi" will be described, InFigs-l, 2 and 4" t he roving from one spool only is shown'jfor the s'ake of clearness, Q i I also mount on the lower uidq rail 32,- and. thencefpas'ses" throng one ofjthe'bottom eyes of guide B,"
thence under the lower back and middle drawing rolls and up between the front drawing rolls as shown.
The drawing rolls are'of the well known type, and may be set in the usual manner in accordance with the amount of draft on the roving desired, and the thickness of the cover for the core yarn which is wanted. They are arranged in sets, of which. 2225 are the feed or back rolls; 2124 the intermediate or middle rolls, and 2023 the delivery or front rolls. These sets of rolls are of successively increasing speed, from the feed to the delivery rolls. The bottom rolls are preferably of metal and fluted, While the top rolls are preferably covered with padding and leather.
The guides B of which, as shown, there is one for each two spindles, are carried by the traverse bar 34, which moves back and forth from side to side of the frame behind the drawin rolls in a Well known manner, and by w'el known mechanism. Each is shown as having at the top, trumpet guide eyes 35 and 86, each of a size to allow the passage of the undrawn roving, and at the bottom, each directly underneath, a top guide eye, the bottom trumpet guide eyes 37 and 38, each of a size to permit the passage of the core. yarn from a spool 30.
The roving 11 passesdirectly through all the sets of drawing rolls and is drawn out to the extent desired, while directly underneath it and so guided by an eye, such as 37 M38, the core yarn 31 passes below the bottom, back and middle rolls and joins the flattened out roving, preferably directly at the center thereof, as it enters between the front or delivery rolls As soon as it emerges, it is revolved by the action of its spindle 40 and bobbin 41, and is spun andlaid upon the bobbin in the usual manner by the action of the ring 43 and traveler 44. In Fig. sum uide wires 46 are shown as directly in line with, or in the same plane with the middle oint of. the traverse ofa guide-anda s indie, and for the best .results I prefer suc an arrangement.
, On some frames however, as shown in Fig. 6, on'account of the length of the draw-- in}; rolls and their arrangement, the distance between ad'oining guide eyes, such' as 60 and '61, is less 1; an that between'spindles 62 and 63,- and theguide wires 64'and 65. This has a tendency to pull thecore yarn away; from the cover and to counteract this I may use a" guide such as shown in Fig. 4, which con- I sistsof a wire 71' having a loop 72. atthe I I art of creel A, spools: 30, 30 on each-of w ich is wound, -spulnf'or'twiste'd yarn 31, and each of. which j-is fsof'fmounted asto'be' rev'oluble'by the pullz "thereof; .J. Theyarn 31 may be guided by end of an arm 73bent upwardly at one end and havinganother 1 arm 74 bent upwardly at the-other end and fastened directly underneath a roving guide eye-75;. carried by traverse"bar34. .With this type of guide, the core yarn may be guidedal-l'nost directly into the roving as it enter'sthe delivery rolls, and
inseam i As the roving on spools 10 may be of any desired size, very short stock can be used,
and this can be drawn down by the drawing rolls to be ver fine by regulating the speed,
by using smal sized intermediate and delivery rolls, and setting them closely 'to-' gether. The roving will thus hold together, and its longer fibers will tend to move toward the center, so that as the core yarn is directly in the center and both are revolved at once as they leave the delivery rolls,- a
7 very strong-even yarn is produced, having the core at the center and next-thereto the long fibers, while the short fibers are on the outside.
It is evident that it makes no difference which way the yarn is revolved.
