UNITED STATES PATENT OFFICE Application filed March 25, 1931. Serial No. 525,048.

This invention relates to upholstery edges of the type shown in my Patent N 0. 1,741,- 413 antedDeoember 31, 1929, this invention ing an improvement thereon. Primaril this invention has for its obJect to provi e an edge presenting a smooth contour for the support of the upholstery covering and which may be flexed without in ury an to provide a portion for attachment to the frame or other part of the furniture whlch is strong and durable. To this end the edge consists of a body portion comprising a loosely felted material enclosed 1n a fabric covering to which the felted material is not intimately bonded, so that these parts may move on each other as the edge is flexed, and an attaching fin portion projecting from the body and also comprising interfelted material oovered with fabric, but in this portion of the edge the felted material and fabric are intimately bonded and secured together. For a more complete understandlng of this invention reference may be had to the accompanying drawing in which Fi ure 1 is a perspective of a piece of materiaf which ma be used in the manufacture of the improve edge.

Figure 2 is an inverted plan of a strip of the material shown in Figure 1.

Fi re 3 is a perspective showing the strip of figure 2 with a core member secured thereto.

Figure 4 is a plan of the complete edge formed up from the material of Figure 3.

Figure 5 is a section on line 55 of Figure 4. v

Referrin to the drawing, Figure 1 illustrates a we of material comprising a layer of fabric 1 such as burlap or the like carrying on one face thereof a layer of loosely felted material such as 2 which may be of hair, jute, or the like. At intervals spaced widthwise of the vweb this felted material is condensed and secured intimately to the fabric 1. This may well be done b the operation in the trade known as nee ling wherein a gan of, needles is passed downwardly throng the felted material and the fabric over the desired areas, pushing this felted material more or less into and through the fabric uniting them throughout substantially their entire confronting faces. These longitudinal zones of felted material condensed and united firmly to the fabric are shown at 3 and they are spaced by portions 4 which are left in loose condition and less firmly bonded to the fabric layer 1. This web is then cut into strips substantially cen- -trally through the needled zones, each strip having the felted material along its margin co firmly united to the fabric margin while between these margins the felted material remains in its original loosely felted condition and not intimately secured to the fabric.

Figure. 2 shows the back face of one of 66 these strips, the felted material showing through the fabric along the margins as at 5 while the weave of the fabric shows over the intermediate portion of the strip width as at 6. A narrower or core strip of the 70 felted material is also cut, this being shown at 7 in Figure 3. This strip is superposed along the center of width of the strip shown in Figure 2 and is preferably secured thereto as by a line of longitudinal stitching 8,75 although it may be unsecured if this is desired.

In order to maintain this narrow core strip 7 in coherent condition it will usually be found desirable to cut it from felted material having a fabric backing similar to the material from which the wider strip is formed and -also to needle this narrow stri so as to unite the felted material to the fabric layer. This, however, is not essential. If the narrow core strip is made with a fabric backing, this strip is referably laid on the Wider strip with its abric backing remote from the wider strip. The narrow strip having been superposed in the proper position on the wider strip, and secured if desired by a row of stitching, the two are then folded longitudinally so as to fold the narrow strip into the form of a substantially cylindrical core, as shown at 10 in Figure 5, and to wra the wider strip thereabout with its fabric covering 1 on its outer face, while the needled margins of the wider strip are brought together and secured by one or more lines of 1 stitching as at 12 and 13 in face to face relation. There is thus formed a substantially cylindrical body or bead portion 15 comprising the intermediate portion of the wider strip wrapped about the narrower strip as a core, and an attaching fin portion 16 projecting therefrom.. The margins of the wider strip forming the outer edge of the fin portion are preferably bonded together by over edge stitching 17. The fabric 1 over the bead portion of the edge, not being intimately united to the felted material enclosed thereby, is free to slip thereon as the bead is flexed so that the bead portion remains in flexible smooth condition in service and maintains a smooth foundation over which the upholstery covering material is drawn. Flexure of the strip is mainly perpendicular to the plane of the fin so that the line of stitching 8, if this is used, lies in the center or neutral plane and does not prevent the desired relative slippage between the fabric and underlying materia Within the fin portion, on the other hand, the felted material and the fabric are intimately united over substantial areas as through the preliminary needling operation, and by the lines of

stitches

12, 1B and 17 and form a strong support for the reception of the fastening devices by which the edge is secured in position. The needling operation prevents the over edge stitches 17 from pulling out or unraveling the outer threads of the fabric covering. It has been found by actual experience that if the fabric and the felted material be intimately secured over the bead portion as by needling, flexure of the head causes the felted material to give way or break locally so that the bead becomes bunchy and non-uniform in its flexibility so that the fabric upholstery covering does not lie smoothly thereover, thus greatly impairing the appearance of the furniture.

Where the core strip is provided with the fabric and the fabric is positioned on the face remote from the fabric covering of the enveloping or cover strip, this fabric layer is folded longitudinally on itself in the finished edge so that it is located at the center of the bead transversely to the fin and at the neutral axis'of the bead Where no substantial slippage occurs during flexure. This fabric strip may thus be intimately united with the felted material without disadvantageous results and this is of considerable advantage during the cutting and handling of the strip as its integrity is more easily maintained. Moreover, since it is embedded within the core portion, even though it should be broken away locally from the felted material, it is so cushioned by the surrounding material of the wider strip that no detrimental effects are produced in the appearance or function of the edge. While the use of a core comprising a folded strip of felt is preferred, this invention in its broader aspects is not limited at 12 may to the use of a core so constructed or to the use of any core.

While two lines of through and through stitching 12 and 13 for securing the strip margins together at the fin are illustrated, one

be used 1f desired. The over edge stitching ties the material together firmly over the edge of the fin so that it is not liable to pull out under service conditions and due to the intimate uniting of the fabric and the felted material, a good hold for the over edge stitching is afforded.

From this description of an embodiment of the invention it should be evident to those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention as defined by the appended claims.
