1 Claim.
This invention relates to methods and apparatus for spinning and/or packaging yarn for filling shuttles and its object is to provide a novel method and apparatus which increase by as much as 30% or more-the amount of yarn that can be carried by the conventional shuttle. I have achieved that result by winding the yarn on the bobbin in apparatus which presents the combination of a spindleless driving mechanism and abobbin to be used therein that is solid rather than axially bored as heretofore, and thereby is of considerably smaller external diameter and of larger capacity than prior hollow bobbins used on spindles. To increase further the amount of yarn on the bobbin I wind it under strong tension and where the yarn is a spun yarn,
such as cotton or the like, I complete the spin-'- ning before winding the bobbin so that during such winding the yarn has suflicient strength to withstand the tension without breaking.
In the drawing:
Fig. 1 is a diagrammatic representation of a spinning frame;
Fig. 2 is a diagrammatic view of winding apparatus suitable for my purposes;
Fig. 3 is a side view of my novel bobbin; and
neighborhood of of an inch or less, as contrasted with an external diameter of of an III Fig. 4 is a section on the line 4-4 of Fig. 3'. v
I have illustrated in Figs. 3 and 4 a bobbin of novel construction embodying my invention by which; in part, I am able to increase considerably the amount of yarn that can be carried by a filling shuttle. :The principle of myv bobbin may be embodied in bobbins of various shapes and sizes for packaging cotton, rayon or other yarns. For purposes of illustration only, I have.
shown a cotton bobbin approximately 8% inches long. It has a head 42 which may be of usual size, shape and construction (approximately 1 inch external diameter) and with the conventional rings IIIIL. The tip 52 at which the opposite end of the bobbin terminates being enlarged ,modates' the usual devices on the lathe in which the'bobbin is turned. As a .result of this solid shank construction, the external diameter of the inch or more in a conventional bobbin of this size and shape. This substantial reduction in size of the major portion of the bobbin shank eil'ects a very substantial increase in the length of yarn that may be carried by the bobbin and yet readily received within the cavity of the con ventional shuttle.
The bobbin illustrated is of the type adapted for an automatic shuttle changing loom having the conventional feeler mechanism which detects a depleted package by feeling the package adjacent the head end portion of the shank designated IIII. To coordinate with that type of feeler mechanism; 1 enlarge the portion III! of the shank to the necessary size, about of an inch in diameter in the bobbin shown. The portion I III may be conveniently an inch and a half long .in a bobbin of the type illustrated and merges,
' entire length, or it may taper slightly as is conformed, preferably employing my novel bobbin I above described. It the yarn is of a type that does not require spinning, such as filament rayon, the method steps of my invention will pertain only to winding on the bobbin, as illustrated in Fig. 2, but for spun yarns of cotton, rayon and the like my method provides preferred steps of spinning and bobbin winding.
In Fig. 1 I have diagrammatically illustrated a machine of suitable type for spinning yarn in accordance with the method aspect of my inven-;
tion. It, according to the system conventionally employed for spinning the given type of.
yarn, there is more than one spinning operation,
such as an initial spinning on a roving frame and a final spinning on a ring spinning frame, the apparatus of Fig. 1 is the machine on which the last spinning operation is effected and it may be a roving frame or, as illustrated. a ring spinning major portion I08 of the shank may be in the 55 frame. The creell has a large number of bobbins 4, of yarn or roving tobe spun. At 6 are indicated the drafting rolls to draft the filaments I which pass thence through a pi'gtail eye II and the core of the package I4 is mounted;
All of the foregoing details may be of conventional construction'except that the package I4 is preferably two, three or more times as large as could be received within the filling shuttle. The package may conveniently conform to the size of the usual warp bobbin and; indeed, the spinning frame it may be a warp spinning frame.
.The package I4 of spun yarn is removed from the spinning frame and is rewound as illustrated in Fig. 2. The creel 30 carries spindles 32 on which preferably several packages l4 are placed and the yarn from each package is wound on a bobbin 40 of the construction above described. 'I'hehead 41 of the bobbin is received within a cup 44 secured to shaft'46 power rotated from a suitable power source, as indicated by the pulley Yarn drawn off the end of. bobbin I4 is threaded through the guide 10 and through the friction disks l2 and 14. These friction disks may be of conventional construction, composed of pairs of convex disks spring pressed against each other as indicated. After passing through guides "II the yarn is threaded through the eye It ofa plate carried on rotating screw 1| operated to effect a traverse motion 'as the yarn is wound on the bobbin to form the package represented at It. The external diameter of the portion I of the shank is nogreater than one-half the external 4|. Within the cup 44 is a layer of resilient material ill against which the bobbin is pressed from its opposite end 52. The tip 52 is received within a second cup 54 carried on a shaft 56 having a free sliding fit in an orifice '58, drilled in the frame. A spring 60 interposed between a sleeve 42, secured to shaft 56, and frame 64, yieldingly urges the cup 64 in the direction of. cup 44 to diameter of the package.
It will be noted' that the driving means for the bobbin in the winder eliminates the use of a spindle, thereby eflectively utilizing a bobbin with solid shank and hence of unusually small external diameter and large yarn capacity. The tension devices 12 and." further increase this quantity of yarn and as the spinning of the yarn,
if any, is completed before winding on to the'bob bin the yarn has sufllcient strength to withstand 7 this tension.
I claim:
In apparatus shuttles, the combination of a yarn receiving core having a head of predetermined diameter. a spindleless driver engaging the head to rotate the core to wind yarn thereon, a shank forming a por tion of said core, which, throughout the major portion of its length, is solid in cross section and of a thickness less than approximately one-half the diameter of the head, a tip, on the opposite press= bobbin head 42 firmly against the resilient layer II. Suitable means, suchas a collar 66 or the like, fixed to the end of shaft '56 projecting outside of frame 64, prevents the withdrawal of the shaft from the frame.
To insert the bobbin the cup '54 is retracted against. the pressure of spring to. the head 42 of the bobbin is inserted in cup 44 and-cup i4 is released against the bobbin. Asa result of the pressure of head 42 on the material 50, there is sufficient friction to drive the bobbin without slippage. A thrust bearing 61 having plat 80 concaved'to receive the tip 52 of the bobbin freely permits such rotation.
end of the shank from the head, of a thickness exceeding that of. the shank to present a shoulder for minimizing flu-mng ofl of the yarn over the tip, a cup adapted to support said tip, and means.
for guiding yarn into direct engagement with the shank throughout its entire length to form a packagewhich directly engages the shank and which throughout the major portion of its length" has an internal diameter less than approximately one-half the external diameter of the head.
