What is claimed and desired to be covered by Letters Patent in the United States is

1. A sleeve for utilization on the surface of a yarn carrier comprising: a single ply of flexible material having predetermined surface characteristics; said sleeve being conical with a slight overlap of edges of a blank; and said overlapped edges secured by an adhesive having electrical conductive characteristics, whereby said sleeve may be interfit with a yarn carrier for overcoming and eliminating surface irregularities while establishing the desired carrier surface for proper delivery of yarn wound thereabout.

Description:
This invention relates to a yarn carrier and, more particularly, to a single ply slip sleeve for modifying the surface characteristics of such carrier.

It has been well known for many years to utilize both plastic and paper carriers and especially cones for the storage and transportation of yarn for use in the textile industry. It has been determined to be of extreme advantage to have various configurations and characteristics for the surface of these carriers in order to facilitate delivery of the yarn from the carrier in the various textile converting processes. However, the transportation and storage and handling of carriers creates defects in the surface and causes mars, scratches, and similar damage which may preclude the proper delivery of the yarn and may cause a complete breakdown in the converting operation.

Plastic carriers have been provided with various surface characteristics but these surfaces are easily damaged in transportation and handling and the high cost of a plastic carrier requires several uses in order to economically compete with paper and less expensive carriers. Moreover, the size and weight of both plastic and paper carriers creates storage and freight problems which can only be resolved by expensive measures.

In order to overcome the disadvantages of the prior art, the instant invention contemplates a single ply slip sleeve for covering the surface of the carrier on which the goods are to be wound to provide preselected surface characteristics. Although the invention is shown and described as applied to a conical yarn carrier, it is to be understood that the concept is considered applicable to tubular carriers.

Accordingly, it is an object of the instant invention to provide a slip sleeve which may be utilized for a further modification of color and coding identification for yarns being wound on the carrier.

Another object of the instant invention is to enhance the delivery characteristics of the surface of a yarn carrier and permit the reuse of damaged carriers.

A still further object of the instant invention is to provide a paper slip sleeve of single ply construction for providing a medium for varying the characteristic of a yarn carrier surface.

Yet another object of the instant invention is to overcome the deterioration of paper yarn carriers effected by long periods of storage, as well as insuring the proper identification and surface characteristic for the carrier.

A still further object of the instant invention is to provide a conical slip sleeve for modifying cone surface characteristics and which may be provided with a surface permitting controlled absorption of the oils with which the yarn is treated, flocked surfaces and various surfaces assisting in enhancing the delivery characteristics of the yarn from the cone.

The invention may be best understood by reference to the accompanying drawings wherein like numerals refer to like members:

FIG. 1 shows an isometric view of a conical yarn carrier having the instant invention applied thereto;

FIG. 2 shows a blank from which the instant invention may be formed;

FIG. 3 shows a completed yarn package in accordance with the instant invention;

FIG. 4 shows a side view of a cone having the instant invention applied thereto;

FIG. 5 is a cross-sectional view through the lap of the joint of the instant invention; and

FIG. 6 shows an enlarged side view of a portion of the joint of the instant invention.

Referring now to the drawings and more particularly to FIGS. 1 and 2 wherein slip sleeve 10 is shown located on cone 30. Slip sleeve 10 is made from blank 12 having edges 14 and 16. Adhesive 18 is applied along the edge 14 in order to secure the edges 14 and 16 together and thereby provide a truncated cone configuration having narrow upper edge 22 and the bottom edge 24. It is to be noted that adhesive 18 may be applied to edge 16 or on the reverse of edge 14 in order to permit overlap 20 to be directed in the direction of removal of the yarn. That is, the upstanding edge of blank 12 when formed into slip sleeve 10 should be such that as the yarn is removed it is pulled from the high side and there is no possibility of the yarn hanging or snagging on the raised lap portion of either edge 16 or 14.

Cone 30 may be of conventional construction as is well known in the textile industry and may be either of paper, metal, wood, or plastic as is well known. Cone 30 includes narrow end 32 and larger end 34 which may have relative sizes with regard to one another of varying degrees to establish any of the various degrees of slope for the surface 38. It is to be observed that insert 36, see FIG. 1, may be utilized for designating the various types of yarn.

As shown in FIG. 3, yarn package 40 is made up of cone 30 with conical slip sleeve 10 thereabout and yarn 42 wound therearound. As is well known, yarn 42, especially that of recently developed synthetics, provides a considerable tension and thus compressive force on the cone on which package 40 is made. In order to prevent package 40 from sliding from cone 30, it may be desirable to utilize a roughened surface 38 on cone 30. For example, a high-mark type paper may provide sufficient surface irregularity to utilize the compressive forces of the winding of the yarn to prevent sloughing. Thus, the winding tension can be utilized for marrying the sleeve to the cone. This in essence would provide a type of lamination and would not be limited to a high-mark type paper, but could be a grooving, either vertically or circumferentially, on the cone surface. A ground surface or any other roughened configuration which would establish some type of projection could be utilized. Obviously, the roughened surface is very helpful in providing a means of retaining the slip sleeve on the cone. A grooved, roughened or high-mark paper type surface is useful in that the synthetic yarns are wound on the cone with substantial tension which effects a compressing force on the slip sleeve and serves to lock the sleeve to the cone. However, it is to be understood that in some applications the material from which sleeve 10 is made may have sufficient strength to support the yarn in the package without the use of the cone. It is also possible to utilize pressure-sensitive adhesive 18 on the back of the sleeve 10 for securing the sleeve to cone 30. Such adhesive is known to have strong shear characteristics, but to be very weak in peel. Therefore, slip sleeve 10 could be removed from cone 30 with minimal effort but would be married to the cone surface with an adhesive.

Adhesive 18 may be of any known type or of any composition which is compatible with the purposes for which it is intended. For example, it may be desirable to utilize a starch base adhesive in some applications and in other applications to utilize a resinous type adhesive. However, in some instances the adhesive may bleed through lap 20 of sleeve 10 and tend to discolor or dye the yarn which would cause imperfections in any woven goods. Moreover, it is possible to utilize graphite or similar conductive material in adhesive 18 and thereby convey static electricity which tends to build up on the yarn package from the package to the spindle or cone support. It is possible to provide electrically conductive adhesive 18 and/or embed metal in the material or adherred to the surface of the material from which sleeve 10 is constructed.

As noted herein, the instant invention permits many advantages by providing a yarn carrier surface covering that is adapted for utilization of a multitude of surface characteristics as known in the textile industry. It is possible that sleeve 10 may have filter characteristics to permit use of cone 30 in yarn dyeing operations. The minimal storage volume required by each sleeve will permit large quantities to be maintained in inventory in a space substantially less than that required for relatively thick-wall cones. Thus it is seen that the inventory could include not only various modification markings, but could have various surface configurations readily available and at the customer's disposal with minimal inventory requirements for the supporting carrier. For example, if the conical slip sleeve is made of 0.005 inch paper or plastic film, the sleeve would occupy from 1/25 to 1/50 of the space for shipping and storage as the equivalent in supporting cones of 0.125 to 0.250 wall thickness in inches. The slip sleeve minimizes or completely eliminates yarn carrier surface irregularities and damage problems. It is possible to orient the overlapped seam to assist in control of yarn delivery and avoid snags which can be a major factor in many operations. The multitude of colors available for the cones, as well as various colors for the sleeves and end inserts permits an extremely wide variation of identification symbols both for the yarn and carrier surface characteristics.

It is possible to establish a controlled absorption of anti-static oil which is on the surface of the yarn which would not be absorbed by a plastic cone and which may be absorbed at too great a degree by a paper cone. Moreover, the anti-static oil tends to migrate to the cone surface and it is undesirable to have this layer of oil due to the delivery characteristics being altered during the removing of the yarn. This "flooding" of the yarn with oil at the cone surface would be prevented and provide a uniform delivery of yarn.

Paper cones tend to deteriorate after long periods of storage and the oil from the yarn tends to attack the lacquer finish on many of the cones and bleeds into the yarn causing discoloration and similar undesirable characteristics. It is possible by utilization of a paper cone slip sleeve that the deterioration can be avoided because it would be unnecessary to keep the cone in storage. Moreover, it is possible to utilize plastic cones which have short surface lives but are available for many repeat uses. It is also possible to vary the dimension and compression characteristics of the cone surface and overcome surface imperfections by modifying the paper dimension and compression character to determine coverage factor of cone surface imperfections. It is possible to eliminate static electricity by the metallic adhesive or other embedded conductive materials in the paper.

A further advantage of the instant invention is that after the yarn package is made there usually exists "a pigtail" which the tender or operator secures in a notch at the base of the cone. The utilization of a paper slip sleeve will permit a more secure attachment of the pigtail to the cone.
