4 Claims.
The present invention relates to coated fabrics and its principal object is to produce a bias woven narrow strip of such fabric in indefinite length.
The invention constitutes an improvement over the subject matter of U. S. Patent No. 2,059,792, issued November 3, 1936, to the present assignee by assignment from Clarence B. Hill.
As explained in the Hill patent, narrow strips of fabric coated with pyroxylin or analogous material are extensively used in the making of welts, gimps, bindings and related articles in which it is necessary to dispose the article, and hence the narrow strip, around turns of short radius in the plane of the strip. To negotiate such turns without objectionable kinking or puckering, it is necessary that the textile fabric which comprises the body of the strip and serves as the foundation or backing for the surface coating be woven or. cut on the bias. This means that the threads are arranged at substantially forty-five degrees to thelengthwise edges of the strip, which greatly facilitates smooth bending or curving `the strip. It is impractical to weave on the bias, and difiiculties are presented when square woven cloth is bias cut because it then becomes necessary to sew or otherwise fasten the ends of the cut sections together to produce the necessary strip of long or indenite length. It is necessary to join sections together because the diagonal cutting of a iiat sheet woven as wide as the loom will permit results in separate strips which are much too short to be used commercially in welt, gimp or binding making where economical operation of the machines and the demands of the trade require that the product be made `in uninterrupted lengths of a hundred yards or more.
The subject of the Hill patent, and other methods which have been practiced or attempted to be practiced in this art, involve cutting the flat yard goods diagonally and thereafter sewing the resultant strips end to end. The present invention provides an improvement which comprises rst sewing the yard goods into tubular form,` then applying an adhesive or cement to the joint, and thereafter spirally cutting the tube to peel off from it a continuous, uninterrupted narrow strip in which the threads cross each other on the bias and which is characterized by regularly spaced diagonally extending joints which are secure and inconspicuous.
v To this end the invention comprises, in certain preferred forms of embodiment, the method and the product which are illustrated in the accom- 2 panying drawing and which are defined by the appended claims. But the invention is to be understood as not limited to these specific embodiments, since it is capable of being practiced otherwise Within the scope of the claims.
Referring to the drawing,
Figure l is a perspective view of a piece-of coated yard goods with its longitudinal margins folded over on to each other and sewed together in accordance with the first step of the method;
Fig. 2 is a perspectiveview of the material of Fig. l with the edges of the material at the seam foldedA back on the body of the goods and cemented thereto, in accordance with the second step oi the method;
Fig. 3 is a similar View showing how the strip of bias woven material is spirally cut from the tubular body;
Fig. i is a top plan view of a short length of the final product showing one of the joints therein;
Fig. 5 is a bottom plan view of the length shown in Fig. 4; and
Fig. 6 is a cross sectional view, taken on the line t--E of Fig. 4, greatly enlarged and somewhat distorted to show clearly the relationship of the parts at the joint. I
In these drawings the reference numeral I designates a strip of yard goods of square woven coatedmaterial which has been folded along its longitudinal center line to bring its lengthwise edges in accurately superposed relation for joining in a lap seam by means of a line of stitching 2. The material is available from the looms and coating machines in wide strips of great length. The product is the kind commonly called imitation leather, having on one side a surface coating of pyroxylin, rubber, vinyl compound or the like, producing a hard permanent finish which may be of any color and may be glossy or dull, or grained to simulate natural leather or to provide any other ornamental appearance within a Wide range 'of selection.
The coating is carried by only one of the two surfaces of material, designated the surface 3 in the drawing. 'Ihe back surface of the material, designated is commonly left unfinished or uncoated because it is not exposed or visible in any of the numerous uses to which the product is ultimately put.
This coated material is available in widths equal to the capacity of ordinary looms on which the basic textile material is woven. Since the original material is necessarily square woven, it is Vnecessary to cut it diagonally, at approximate- 1y 45, to produce from it narrow strips of bias weave. It will be evident that, assuming the coated sheet material to be sixty inches in width, a strip out at 45 from it will be only approximately eighty-iive inches long. Splicing such strips end to end, as propsed by the Hill patent and by other prior art methods, requires a separate stitehingforfother splicing operation' to be performed at eighty-ve inch: intervals. Theexpense of such operations is considerable, and unless particular care is taken to provide anunusually strong kind of seam or splioeiy there..-h sulting joints are weak and the product is th'us objectionable.
The present invention provides-a superior*jointY and enables it to be made Without a special operation at the adjacent ends o-.eaeh two lengths of cut strip material.

The cutting is done continuously' on a tubular body of indefinite length and the result is a strip Svor a plurality of strips s having the length othefbedy having at equally spaced intervals preformed strong joints crossing the strip diagonally, as showrrin Figs. e and 5.
