Application October 28, 1953, Serial No. 388,795

1 Claim. (Cl. 2-278) My invention relates to ornamental edgng for fabrics, and relates particularly to the use of knitted tubular braid sewed or embroidered onto the fabrics to obtain a pleasing and decorative edge.

The familiar plaited or woven braids, tapes, or ribbons have not been used to make a sewed down ornamental edge of segmented pattern because these materials do not lie flat at the turns or corners where the segments repeat themselves. An example of this is the scallop pattern, where, if woven or plaited braid is used, the braid turns up at the corners, does not lie flat and shows an unsightly upthrust, or protuberance, overlap, or fold; thereby marring the appearance of the edge.

It, therefore, is an object of my invention to produce an ornamental edgng made of knitted tubing for fabrics wherein the corners or indentations of a segmented pattern are flat and undistorted.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically applied, and which is highly eflective in its application to fabric material.

With the above and related objects in view, my invention consists in the details of Construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing, in which:

Fig. 1 is a view of the fabric and knitted tube itself.

Fig. 2 shows the knitted tube sewed to the fabric.

Fig. 3 is a sectional view taken along the lines 3--3 of Fig. 2.

Fig. 4 is a view of the tube forming a scalloped edgng when sewed to a piece of fabric.

Fig. 5 is a very large view showing the knitted tube with its loops as it isstitched upon a piece of fabric. This is a highly exaggerated view with the loops being bunched together where there is a narrow radius of curvature or a sharp bend, and the loops are spread when there is a large radius of curvature.

Referring now in greater detail to the drawing wherein similar characters refer to similar parts, I show a fabrc material, generally designated as A, and a knitted tube,

generally designated as B, which is used as a decorative 5 edgng for the fabric A.

The tube is sewed to the material A to form a scallop or other ornamental type of edgng by means of a series of zig-zag or any other type of stitches 10. It is found that where the scalloped segment is repeated, the corner formed thereby is sharp without rise or overlap, and is flat and undistorted.

It is found that the outer edge (unsewed edge) of the knitted tube forms a clean corner where the direction of the line or curve of edgng reverses itself.

Tape cannot satisfactorily be used since it has a tendency to overlap when the tape changes its direction, as occurs in a scalloped edgng.

In Fig. 4, I show the knitted tube B wherein the tube is sewed by stitching passing through the tubing wall and through the interior of the tubing, and through the fabric in a segmented or scallop pattern, and the fabric is cut away underneath the tubing, leaving the tubing as an attractive, undistorted edgng for the fabric. As the stitching passes through two overlapping portions of the tube B, the tube will be flat upon the fabric.

The knitted tubing B serves to have the loops telescope or be bunched, as at 11, Fig. 5 at the short radius curve, and the loops are extended or stretched, as at 13, Fig. 5, at the greater radius corner curve-this results in the tubing lying substantially flat upon the fabn'c without any distorton or overlapping of the corners when the tubing B is sewed to the fabric.

The row of stitches 10 passes entirely through the fabric A and the flattened sides of the knitted tubing B as shown in Figs. 3, 4, and 5 to obtain the hereinbefore mentioned desired result. The elasticity of the tubing itself is utilized to permit the stretching whereby an attractive, clean appearing edgng results.

Although my invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention:

In combination with a fabric, a flattened knitted tubing having loops and longitudinal edges for forming an edgng having progressing repeats of a pattern and having converging portions to form a series of corners, each of said corners having long outer and short inner curves, a series of stitches passing entirely through said tubing and said fabric adjacent one flattened longitudinal edge of the tubing to hold said tubing to said fabric, said tubing changing its direction at said corners to form said repeats whereby the loops of said tubing telescope one another at the short inner curves and the loops are extended at the long outer curves whereby said flattened tubing lies in substantially the same plane at said corners.
