2 Claims. (Cl. 2-278) My invention relates to an ornamental embroidered trim for fabrics, and more particularly relates to a plaited braid which is sewn upon fabric to present a pleasing and decorative raised appearance.

In the applying of ornamental trim upon fabrics, it has been found that the familiar plaited or woven breads, tapes or ribbons cannot be satisfactorily used because of ytheir tendency to curl and buckle at their extremities whenever moderately severe curvature in the pattern is imposed. These braided materials do not lie at, particularly at sharp corners, because of the tendency of the interweaving to crowd and overlap, thereby resulting in unsightly upthrusts, folds and protuberances to mar the edging appearance. While it is desirable to further extend the breadth or width of woven trim in order to simulate laborious embroidery and needlepoint designs, as by plaiting a plurality of interwoven braid, excessive stitching would ordinarily be required because of the braids inability to lie flat.

it, therefore, is an object of my invention to fabricate an ornamental edging comprised of a plurality of knitted braids which are plaited together wherein the plaited assembly may be sewn upon fabric in flat and undistorted pattern with a single line of stitching.

Another object of my invention is to fabricate an ornamental plaited braid edging wherein random corners and indentations of any pattern will remain flat and undistorted.

Another object of my invention is to fabricate an ornamental braid edging giving the appearance of embroidery or needlepoint.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efficient in operation.

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 theaccompanying drawing, in which:

Fig. 1 is a top plan view of a plaited braid embodying my invention.

Fig. 2 is a plan view of the plaited braid sewn upon fabric to form a sharply contoured pattern.

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

Fig. 4 is a perspective view of a single tubular braided element used in the fabrication of the plaited braid.

Fig. 5 is a fragmentary enlarged view showing the knitted braid element with its loops as it is intertwined into the plaited braid.

Referring now in greater detail to the drawing, wherein similar reference characters refer to similar parts, I show a plaited braid, generally designated as A, sewn in an irregular pattern upon a piece of fabric material, generally designated as B.

The plaited braid A comprises a plurality of knitted tubular braid elements which are plaited together, each 2,810,133 Patented Oct. 22, 1957 ice .tubular braid-.element ybeing knitted-or wovenin a series -offintermeshed loops as shown in Figs. 4 and 5 4and as further-describedin my United States Letters PatentNo. 2,103,406.

In Fig. 5, `Ir show the braided elements ..10 .flattened .and yintertwinedon each other in a sinuous manner to define vra plurality yof ,inner 'radius bends Q12` where the braided elements abut kone another, Iand a pluralityof outer Iradius bends 14,at the external periphery. yItis ltonbe-.observed that the inner radiusl bends 12 are in Zcompression, .and `the knitted loops-are telescoped and '.bunched, .while the outer radiusvcurvcs 1.4 `are in-tension and are extended and stretched. The facility with which these knitted loops slide over one another at any curvature results in the braided elements lying in smooth contours when they are flattened and intertwined into plaited braid.

In Fig. 2, the plaited braid A is sewn to the fabric B to form an ornamental pattern by means of a series of stitches 16. Only a single line of the stitches 16 is necessary and the plaited braid A rests at upon the fabric giving the appearance of embroidery, thereby simulating the effect of each braid loop pervading the fabric itself. The single row of stitches 16 passes through the fabric B and the center portion of the plaited braid A, as shown in Fig. 3. The elasticity of the braided elements 10 again are utilized to accommodate stretching and compression as the pattern proceeds upon the fabric at any break corner, or curvature. For example, in Fig. 2, a plurality of corners 20 are formed, whereby an external llet ZtlA is defined at the greater radius of curvature and an internal fillet 20B defined at the short radius of curvature. Because of the telescoping of the loops, the sharp fillets 20A and 20B are defined without distortion or overlap and the plaited braid A lies substantially at upon the fabric when sewed thereon without any upthrust, buckling, or curling. It is to be observed that although I have shown my plaited braid sewn to the center portion of a fabric, this plaited braid is easily stitched to a regular edge of fabric to define a pleasing and decorative scallop.

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:

l. In combination with a fabric, a plaited braid comprising a plurality of tubular braid elements, each tubular braid element being knitted in a plurality of intermeshing loops, the said tubular braid elements being flattened and intertwined with each other to dene a plurality of inner radius bends and a plurality of outer radius bends, the inner radius bends being located at points where adjacent braid elements sinuously abut one another, the intermeshing loops adjacent the inner radius bends being hunched in compression, the outer radius bends being concentric with said inner radius bends whereby the intermeshing loops within the outer radius bends are extended in tension, said plaited braid being sewn to the fabric in an irregular pattern having corners, each of said corners having an internal llet of short radius of curvature and concentric therewith an external fillet of longer radius of curvature, a single line of stitches passing entirely through said plaited braid and axially extending thereto wherein the loops of the braid elements are bunched within the internal fillets and the loops of the braid elements are extended within the external llets thereby enabling the plaited braid to lie flat and undistorted at the pattern corners.

2. In combination with a fabric, a plaited braid cornprising a plurality of knitted tubes, each tube having a plurality of intermeshing loops, the said tubes being fiattened and intertwined with each other to define a plurality of inner radius bends and a plurality of outer radius bends, the inner radius bends being located at points where adjacent tubes sinuously abut one another, the intermeshing loops adjacent the inner radius bends being bunched in compression, the outer radius bends being concentric with said inner radius bends whereby the intermeshing loops within the outer radius bends are extended in tension, said plaited braid being sewn to the fabric in an irregular pattern having corners, each of said corners having internal fillet of short radius of curvature and concentric therewith an external fillet of longer radius of curvature, a single line of stitches passing entirely through said plaited braid and axially extending therei with wherein the loops of the tubes are hunched within the internal fillets and the loops of the tubes are extended within the external fillets thereby enabling the plaited braid to lie at and undistorted at the pattern corners.
