4 Claims. (Cl. 13S-78) This invention relates to an improved form of textile carrier of laminated spiral wound, construction and to a method for forming this carrier as Well as other similar laminated tubular bodies in general.
In the past, textile carriers having a laminated paper construction have characteristically been formed by convolutely winding a paper blank to which adhesive had been applied before winding. A convolutely wound construction of this sort has the inherent disadvantage of being necessarily unbalanced, so that textile carriers formed with such a construction have an undesirable tendency to vibrate excessively at high winding speeds. Also, a convolutely wound construction, because of its inherent unbalance, has a pronounced tendency to get out of round and, further, to shrink after winding as the adhesive dries, so that it is dicult to maintain a uniform inside diameter.
It has been known that a spiral Wound, laminated construction would eliminate the diiculty with balance, because such a construction is inherently balanced, and that a spiral wound construction retains its roundness Well and does not shrink after winding, but spiral winding has not been successfully employed previously in textile carrier constructions because the usual edge abutting disposition of the plies as they are Wound present a discontinous surface that cannot be made to serve satisfactorily as a winding surface for a textile carrier.
According to the present invention there is now provided a laminated, spiral wound construction that makes it possible to form satisfactorily very inexpensive textile carriers which are nevertheless exceptionally well balanced. Generally described, this construction is characterized by an outer ply that is twice as Wide as the adjacent inner ply and that is spiral wound to overlap approximately one-half its width. By this arrangement, the outer ply can be made to present a surface of continuous nature that can be finished to provide an excellent winding surface for textile carriers. Moreover, in this construction l the physical characteristics of the material forming the outer ply may be selected independently of the inner ply material so as to allow the use of materials in the construction to the best advantage from the standpoint of cost, in addition to the fact that spiral winding is a particularly eflicient and relatively inexpensive manufacturing Operation. 1
These and other features of the laminated, spiral wound construction of the present invention are described in detail below, for purposes of representative illustration, with particular reference to the manner in which this construction may be used in the manufacture of textile carriers, and in connection with the accompanying drawings, in which:
Fig. l is an elevation of a textile carrier such as might be formed from paper tubing formed in accordano with the present invention;
Fig. 2 is a similar elevation, in quarter section, illustrating the paper tubing from which the textile carrier in r 2,151,936 Patented June 26, 1956 ICC Fig. 1 might be formed, and indicating the laminated, spiral wound construction thereof; and
Fig. 3 is an enlarged, fragmentary, sectional detail illustrating the arrangement of the laminated, spiral wound construction of the present invention.
The textile carrier shown in Fig. l provides an illustration of an article that might be formed from paper tubing or the like embodying the laminated, spiral wound construction of the present invention. As shown, this textile carrier comprises a cylindrical barrel 10, that provides a Winding surface Von which yarn may be wound in package form, and one end of which may be turned in to form a rounded tip portion or nose at 12, as is common practice.
Fig. 2 illustrates a finished length of tubing 14 from Which the textile carrier in Fig. 1 might be formed and in which the spiral wound construction thereof appears in the inner ply at 16, although the outer surface is shown continuous as a result of the finishing treatment which will be described in detail presently.
rfhe arrangement of the spiral wound construction from which the tubing 14 in Fig. 2 is formed according to the present invention is shown in Fig. 3 as comprising a plurality of inner plies 18 spiral wound in edge abutting relation in the usual manner, and an overlapping outer ply- 2i). This construction may be formed on a conventional spiral winding machine, using any standard type of adhesive, such as a sodium silicate adhesive, for coating the plies as they are wound to secure the resulting laminated structure. ln certain cases, as where it may be desired to form yarn retaining surface configurations on the textile carrier barrel 1i? by scoring the tubing 14 to form circumferential ridges or the like therein, a flexible resin type or other special purpose adhesive may be used.
The inner plies 18 of the spiral wound construction, when a laminated paper textile carrier is being formed, may consist of very inexpensive grades of paper, for these plies 1S function primarily as a filler section, so that the wall thickness desired and the tube strength required are the only important factors determining the number of plies 18 to be provided and the type of paper to be used for them. The outer ply 2i), on the other hand, is formed of a high grade paper having good physical strength and toughness, such as a good quality kraft paper, and is advantageously provided as a relatively thin ply for a purpose which is explained further below.
Alternatively, the inner plies 18 and outer ply 20 may be formed of any flexible ply material capable of being spirally wound. Any flexible fibrous sheet material, in addition specifically to paper, might be used. For example, ply material formed of either woven or unwoven cloth might be used. Also, metal foils and similar material could be used, or any combination of various ply materials of the sorts noted above could be selected for obtaining a tubing 14 adapted particularly for a given nal purpose.
As previously mentioned, the spiral woundV construction of the present invention is characterized by an outer ply Ztl that is twice as Wide as the inner plies 18, or at least the next adjacent inner ply 13 if it were desired for any reason to vary the width of the other inner plies 18, which will ordinarily have a uniform width. Also, the double width outer ply 20 is spirally wound to overlap about half its width, so that instead of the spiral groove or spacing normally occurring between the abutting edges of regularly spiral wound plies, such as the inner plies 18, the outer ply 2u is disposed so that it provides iny effect an interposed ply bridgingthis spacing, as at 20 in Fig. 3.
In addition, it should be noted that by providing a relatively-thinouter ply 29 this arrangement makes it possible to present a substantially continuous outer surface, which is firmly secured in place by the manner in which it is .ness of the linal product.
Vtive to a surface iinishing impregnation.
3 overlapped to the extent of one-half its width. The previously mentioned Spacing between Vedge abutting plies could of course be elirnnated by any degree of overlapping employed, but where the overlapping occurs a void is necessarily formed as the covering lap rises over the, edge it laps, and because of this void a break is formed in the adhesive bond which weakens the laminated Vstructure because there is an added winding strain on the covering lap that Vmakes it difficult to obtain adequate adhesive bonding unlessV the lap is continued Vfar enough beyond Vthe lapping void to provide a Suffiey secured area of the covering lap. By overlapping one-half the width of outer ply 2t?, the maximum adhesively secured area for the covering lap portion is obtained. Moreover, thisdegree of overiapping provides a substantially uniform double-thickness of theouter'ply 2%, whiie any lesser degree would introduce a ridged or banded effect in the outer surface.
The relative thinness inY which the outer ply is provided' will depend upon Vthe useto which the finished tubing V14 is to beV put and on the degree and type'of` finishing treatment employed. In general, the thinner 'Y l the ,outer ply 2i? is,-the smoother the outer finished surface of the tubing 14 will be, but as a practical matter the relative'thinness of the outer ply 2i? may be varied considerably without affecting appreciably the smooth- Also, the eect of increasing the thickness of the outer ply 2Q can be offset through a further range by increasing the intensity of the finishing treatment. VIn still other cases, the slight unevenness at the point of overlap may not be significant for the intended use, as whererthe outer surface of the tubing 14 Was to be covered with flock as mentioned further below, and the relative thinness of the outer ply 20 will become still less important.- u Y The subsequent finishing treatment for the spiral wound construction described above to obtain the linished tubing 14 may take place as the spiral wound tubing is formed and before it is cut to length as it comes oi the winding machine spindle, or the finishing treatment may be performed on individual portions of the tubing after vthey are cut to length, orton portions cut in relatively long lengths that will later be cut inV shorter lengthsY after finishing. Y
In any case, Ythe rst finishing step consistsV of surface Yabrading the outer ply 20 so as to render it recep- V This abrading step may VbeA performed for example by passing a continuous sanding belt across the surface of the outer ply 20 as the spiral Wound construction comes off the Winding spindle. The effect of abrading the outer ply 20 in this manner is to nap its surface, so?, that it will impregnate readily as noted above, and also to obscure substantially the exposed edge of the covering lap ofV outer ply 20, by reason of this napping.
Next, the vsurface finishing impregnant is applied to the abraded Vsurface of the outer ply V27). VThis may be done directly following the abrading step while the spiral wound'construction is still extending in a continuous length from the winding machine spindle by disposing a suitable applicator'roll so that it Vdips in a bath of the `finishing impregnant and runs in'contact with the surface of the outer ply 20 Vto transfer the impregnant thereon. 1 Y Y Y Y Y,The treating impregnant may be selected as desired to obtain the finished surface characteristics desired.

The polishing lubricant component of the above ,composition of course acts to make possible the development of a good finish on the surface ofthe outer ply 20. The synthetic resin serves to impart moisture resistance to the treated surface, and the casein provides resistance in treated surface to the processing solvents often carried on the yarn that is Wound on textile carriers.
Following impregnation, the 'surfacefof outer ply 20 is then butfed to develop the desired surface finish. This may be done by passing the spiral ,wound construction, again as it is still extending from the winding machine spindle, through a close fitting leather collar that'mayV hance the resulting surface finish. On the other hand, t
alternative surface treatments may be employed,V such as following the abrading step with the application of an adhesive and then flocking the surface of outer ply 20.V
In short, the particular finishing treatment used may be varied widely depending upon the result desired.
The present invention has been described above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.
