SHEETZUFZ INVEN'TOR CLARENCE W. ANDER ON ATTORNEYS TEXTILE YARN CARRIER WITII IMPROVED STARTING MEANS This invention relates to a textile yarn carrier for use in winding yarn packages and more particularly to a textile yarn carrier including improved means to facilitate the starting of the winding of a yarn package.

In the production of yarn, it is customary practice to wind the finished yarn on spools,.bobbins or other type textile yam carriers to form a package suitable for storage, shipment or subsequent use. The winding of the package is usually started by rotating the carrier at a relatively high speed and frictionally engaging the yarn with the rotating carrier so as to cause incipient winding of the yarn onto the carrier.

It is readily apparent that the design of the textile yarn carrier is an important factor to be considered in how effectively the yarn may be started on the carrier. Numerous carrier designs have been provided including carriers having a circumferential yarn-receiving groove and carriers having an adhesive disposed thereon. These types of textile yarn carriers have not proven to be satisfactory in many instances because they provide erratic results due to moisture and other variables influencing paper stability, provide inconsistant frictional contact between the yarn and the carrier to start winding of the yarn and in the case of adhesives, the adhesives damage a portion of the yarn wound on the package.

Accordingly, it is the object of the present invention to provide a textile yarn carrier having improved means for frictionally engaging and holding yarn brought into contact therewith to facilitate the starting of the winding of a yarn package and which means does not otherwise damage the yarn wound on the package.

By this invention the above object and others are accom plished by providing a textile yarn carrier which comprises an elongate core having a supporting surface and a yarn-receiving groove disposed in the supporting surface and extending at least partially around the core, and yarn catch insert means mounted within the groove for catching the yarn to facilitate the starting of the winding of a package.

Preferably, the insert means includes a base secured within the groove to the core and a plurality of yam-catching fingers extending outwardly from the base at an acute angle and terminating within the groove to define a yarn pinch area between the base and the fingers for frictionally engaging and grasping the yarn as it is brought within the groove. In addition, the insert means preferably includes a plurality of barbs extending outwardly from the base at an acute angle and upwardly of the groove and engaging the core for mounting the insert means within the groove.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

FIG. 10 is a sectional view with parts broken away illustrating a yarn textile carrier employing the yarn catch insert of FIG. 9;

FIG. 11 is a perspective view of a roll or strip of material from which a yarn catch insert may be formed which is similar to that of FIGS. 2 and 3 but formed in a different manner; and

FIG. 12 is a perspective view, with portions broken away, generally similar to FIG. 4, but utilizing the yarn catch insert of FIG. 11.

Referring more specifically to the drawings wherein like reference characters are employed to indicate like parts, there is shown in FIG. I a textile yarn carrier, generally designated at 10, of the present invention. The textile carrier I0 is for winding yarn thereon to form a yarn package for storage, shipment or subsequent use of the yarn and comprises a core 11 having a yarn-supporting surface 12 and a yarn-receiving groove I3 disposed in the supporting surface 12 and extending at least partially around the core 11.

The core 11 may be fabricated from any suitable material, such as paper, wood, metal, plastic and the like, and may take on any conventional shape well known in the textile art, such as cylindrical, conical etc. In the present instance, the core 11 is an elongate, substantially cylindrical paper tube formed by convolute winding to include a plurality of convolute windings lla (FIG. 4) with the outer surface of tube providing the supporting surface 12 for the yarn during winding.

The yam-receiving groove 13 is circumferentially disposed at least partially around the core 11 and preferably adjacent one end thereof so that the winding may be started adjacent one end. The groove 13 is generally V-shaped in transverse cross section and extends inwardly from the supporting surface 12 toward the longitudinal axis of the core 11. The dimensions of the groove I3 are .not critical to the present invention but the depth of the groove should be commensurate with the wall thickness of the tube and the opening of the groove, that is, the length of a line connecting the sides of the groove adjacent the supporting surface 12, should accommodate the yarn to be used.

The textile carrier 10 asthus far described is well known in the textile art and is used by being mounted upon a mandrel or other means for rotation about the longitudinal axis thereof. During the rotation of the carrier 10, the yarn to be wound is brought within the groove 13 where the yarn is frictionally engaged by the sides of the groove 13 to cause incipient winding of the yarn onto the textile yarn carrier 10 to form a yarn package. However, in many instances, the frictional contact between the core 11 and the yarn is not sufficient to cause incipient winding.

To improve the ability of the textile yarn carrier 10 to catch the yarn as it is brought within the yam-receiving groove 13, the textile yarn carrier 10 of the present invention includes yarn catch insert means mounted within the groove 13 for catching the yarn. The yarn catch insert means, generally stated, comprises a base secured within the groove 13 to the core I l and a plurality of yam-catching fingers extending outwardly from the base and terminating within the groove 13 for frictionally engaging and grasping the yarn as it is brought within the groove I3. Preferably, some of the yam-catching fingers extend outwardly from the base at an acute angle downwardly further within the groove I3 to define a yarn pinch area between the base and each of the fingers. Furthermore, in order to mount the yarn catch insert within the groove I3 to the core 11, it is preferable that the insert include a plurality of barbs extending outwardly from the base at an acute angle upwardly of the groove 13 and engaging the core 11. It will readily be apparent that the rapid rotation of the textile carrier I0 will not cause the yarn catch insert to be thrown from the groove 13 since the greater the centrifugal force on the insert the more the barbs will press against and penetrate the core II.

A preferred embodiment of the yam-catching insert means, generally designated at 20, is employed in the textile carrier I0 of FIG. I and is best illustrated in FIGS. 2-4. Referring to FIG. 4, the yam-catching insert means 20 comprises an elongate base 21 having a generally V-shaped cross section wedged within or mating with V-shaped groove 13. A plurality of barbs 22 extend outwardly from the outside of the V- shaped base at an acute angle upwardly of the groove 13 in engagement with the portions of the core 11 defining groove 13 for securing the insert 20 within the groove 13. It will be appreciated that the barbs 22 allow the insert 20 to be selfsecured within the groove 13 in such a manner that the insert 20 will not be pulled or thrown from the groove 13 during use of the textile carrier 10. In order to catch the yarn when brought within the groove 13, the insert 20 includes a plurality of yarn-catching fingers 23 which extend outwardly from the inside of the V-shaped base 21 at an acute angle downwardly further within the groove 13 to define a yarn pinch area 24 between the inside of the V-shaped base 21 and each of the fingers 23. Thus, when a yarn is placed inwardly of the groove 13, it will catch on one or more of the yarn catch fingers 23 and be pinched between the catch fingers 23 and base 21 to start the winding of the yarn on the supporting surface 12 of the core 11. While the length of the insert 20 is not extremely critical, it is preferred to have a plurality of spaced-apart discrete inserts similar to that illustrated in FIG. 4 rather than a continuous insert extending along the entire length of groove 13.

The yarn catch insert 20 of FIG. 4 may be formed of plastic, metal, wood, or other suitable material by any conventional techniques such as extruding, casting or the like. There is illustrated in FIG. 2 a roll or strip S of material that has been extruded to include the base 21, barbs 22 and yarn-catching fingers 23 and may be-folded at its center into the generally V- shape shown in FIG. 3. From the V-shape in FIG. 3 the strip S may be cut into discrete segments along cut lines CL to form discrete inserts 20 which may be wedged within groove 13 as in FIG. 4 to complete the textile yarn carrier 10.

A slightly modified yarn catching insert 20' is shown in FIGS. 5 and 6 and, due to the similarity with insert 20, insert 20' is given the same reference designation with the addition of a prime notation. The modified insert 20 includes a generally V-shaped base 21, a plurality of barbs 22' for securing the insert within the groove 13 and a plurality of yamcatching fingers 23 extending outwardly from the inside of the V-shaped base at an acute angle downwardly further within the base to define a yarn pinch area 24' between the base 21' and each of the fingers 23'. Insert 20' difi'ers primarily in the manner in which it is formed and the materials from which it is preferably made. The insert 20 is preferably formed from a rigid material such as metal or plastic and is formed initially to include the generally V-shape whereby additional forming is unnecessary.

Another slightly modified yarn catch insert 20" is shown in FIGS. 11 and 12 and, due to the similarity with inserts 20 and 20', this insert is given the same reference designation with the addition of a double-prime notation. This yarn catch insert 20" may be formed of a strip S of plastic or other suitable material which has been punched to form a pattern of fingers, as indicated in FIG. 11. As indicated in FIG. 11, the strip S may be cut into suitable lengths and folded to form a generally V-shaped base 21" having a plurality of barbs 22" for securing the insert within a groove 13 of a carrier and a plurality of yarn catch fingers 23" extending outwardly from the inside of the V-shaped base 21 at an acute angle downwardly further within the base to define a yarn pinch area 24" between the base 21" and each of the fingers 23'. Insert differs primarily in the manner in which it is formed and is secured within the groove 13 in the same manner as the

inserts

20 and 20 described above to provide for ease in entry of the yarn into the insert but extreme difficulty in the yarn escaping therefrom.

Other modified forms of the yarn catch insert of the present invention will be readily apparent and by way of example, two such modified inserts and 40 are illustrated in FIGS. 7 and 8 and FIGS. 9 and 10, respectively. Referring to FIGS. 7 and 8, the modified insert 30 comprises an elongate base 31 of less length than the depth of V-shaped groove 13. One end of the elongate base 31 has a plurality of barbs 32 extending outwardly therefrom at an acute angle upwardly toward the other end of the elongate base 31 and serve to secure the elongate base 31 within the groove as shown in FIG. 8. The other or free end of the elongate base 31 which extends outwardly from the bottom of the groove 13 has a plurality of yarncatching fingers 33 which extend outwardly from adjacent the free end of the base 31 at an acute angle and downwardly further within groove 13 to define a yarn pinch area 34 between the base 31 and each of the fingers 33.

With reference to FIGS. 9 and 10, the modified insert 40 comprises an elongate rod or base 41 having a diameter less than the opening of groove 13 whereby it can be placed lengthwise within the groove 13 as shown in FIG. 10. The elongate base 41 has a multitude of barbs 42 extending outwardly therefrom at spaced intervals throughout the length and circumference thereof. Preferably, at least some of the barbs 42 extend outwardly at an acute angle from the base 41. When the insert 40 is placed lengthwise within groove 13 as shown in FIG. 10, a portion of the barbs 42 serve to mount the insert 40 within the groove 13 by engaging and partially penetrating the core 1 1. Another portion of the barbs 42 serve as yarn-catching fingers for frictionally engaging and grasping the yarn as it is brought within groove 13. If, as preferred, numerous of the barbs 42 extend outwardly at an acute angle from the base 41, a portion of these barbs 42 will define a yarn pinch area between the barbs 42 and base 41. In addition, the securement of the insert 40 within the groove 13 will be improved, that is, if the barbs 42 extend upwardly of the groove 13 and engage the core 11.

The use of the textile carrier 10 heretofore described is readily apparent. The textile yarn carrier 10 is mounted upon a spindle or other means for rotation about the longitudinal axis thereof. The yarn to be wound is brought within groove 13 at which time the yarn is frictionally engaged and grasped by the yam-catching fingers of the insert to start the winding of the yarn to form a yarn package. Preferably, the yarn is caught in the pinch area between the yarn-catching fingers and base of the insert. During rotation of the textile carrier 10, the yam-catching insert will not be thrown from the groove 13 since the pull the yarn creates on the insert and the centrifugal force from the rotation of the textile carrier will cause the insert to be more securely held within the groove 13.

From the foregoing description it is readily apparent that there has been provided a textile yarn carrier which includes improved means to facilitate the starting of the winding of yarn thereon which is both economical of manufacture and easy to use.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation.
