BIAS TAPE AND eeocess O MAKING THE SAME.

. EPEGIFICATION forming part of Letters Patent No. 293,440, dated February 12, 188.*

Application filed December 4, 1882. (No model.) I

To all whom it may concern:

Be it known that I, CHARLES H. FARMER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Bias Tape and Process of Making the Same; and I do hereby declarethat the same are fully described in the following specification, and illustrated in the accompanying drawings.

The object of this invention is to produce a perfect article of bias tape formed in continuous strips of bias-cut fabric put up in packages ready for use, and adapted .for bindings, pipings, and the like; and also to provide a process by which the production of such article is greatly facilitated and cheapened. The drawings illustrate certain steps of the process which I employ, and show also the article put up in its merchantable form.

Figure 1 represents aseetion of the original fabric cut obliquely to its warp and filling, which areindicated by the shade-lines. Fig. 2 shows such sections united at their selvages into a band, the shade-lines not indicating the direction of theinterwoven threads. Fig. 3 shows, on a larger scale, this band wound on apasteboard core, and also a stick of the continuous tape cut therefrom with its core; and Fig. 4 represents a cylindrical coil of my bias tape. I I

In the manufacture of my improved tape, I proceed as follows: I take any suitable woven fabric-such as cotton cloth or muslin-of the ordinary widths, and cut it on a true bias of forty-five degrees to its length into parallelograms A, of convenient and uniform size. These pieces I unite into a continuous band, B, by rubber cement or some equally powerful and pliable adhesive substance applied to the sel vages w of each piece, and exposed untilthe naphtha or'other solvent has evaporated suffi ciently for the pieces to adhere at saidedges by pressure. These cemented joints 0 will therefore run obliquely across the band, as in Figs. 2 and 3, and its marginal edges, b,will be the raw edges where the original fabric was severed, (see at b, Fig. 1.) The band, so formed of successive rhombic figures, and having a succession of pliable cemented joints (3 r where said pieces are united by their selvages,

gles to the edges of the pasteboard core,which core is itself out by the operation into disconnected strips, while each'cutting severs a length of tape equal to the full length of the band, and having at intervals the pliable cemented joints 0 described, and at all points the true bias arrangement of the fabric incident to this 0011- This cutting of the band B into continuous lengths of tape is best effected by an ordinary paper-cutting machine, having a' fiat bed to support the material held in place upon it, and a reciprocating cutter making a drawing stroke. NVith such a machine I lay the band to be out upon a thick pasteboard sheet, which the cutting-blade may readily sever, and I clamp to the table a barrier of similar material to support the front edge of the folded band against the thrust of the out ting-knife. Bythese means, while I out to waste the core in the band, the sheet beneath it, and the barrier in front of it, Isecure at each stroke of the cutter a true and uniform stick of bias tape of thirty-six or seventy-two yards length, as the case may be, with edges p el fectly matched at each joint, and pliably united to the extreme edges, so as to make finished work which will pass through the sewing-machine attachments without interri'iption. The strip of the core D, which is severed with the stick of tape, forms, as it were, an elongated spool to hold the tape wound upon it in merchantable shape, or the tape may be coiled into cylindrical rolls for greater convenience in use. (See Fig. 4.)

I am aware that it is the practice of dress makers and others to cut fabrics bias for bindings, trimmings, 8750., and that such bias-cut disconnected strips have been heretofore made and sold to be connected by stitches when applied to a garment or other article; and, also, that separately-cut bias strips of trimming width have been successively and singly stitched together endwise, and subsequently embroidered. I make no claim to any of these things, since it is essential to my process and its product that the series of joints be formed before the tape is cut from the broad band.

I claim as my invention 1. As anew article of manufacture, bias tape put up in sticks or rolls and formed of uniforn; width in continuous lengths of fabric, with a succession of pliable oblique and paralleljoints having perfectly-matched cut edges, Without projecting threads, substantially as set forth.

2. The improved process of making continuous bias tape, consistingin cutting the fabric at an'angle of about forty-five degrees to its
