PROCESS OF FORMING EMBROIDERED EDGINGS.

Application filed August 9, 1923. Serial No. 656,594.

The object of my invention is to improve the process of forming an embroidered, scale loped edge on handkerchiefs and other articles, the material being fed in a straight path and the scallops being formed as the material is fed forward, obviating the necessity of trimming the scalloped edge.

In the accompanying drawings:

Fig. 1 is a view of a handkerchief scalloped and embroidered in accordance with my invention; I

Fig. 2 is a View showing a portion of a handkerchief blank prior to being embroid' ered;

Fig. 3 is a view showing a blank partly embroidered and scalloped;

Fig. 4 is a detached View showing an embroidered stitch on one face of a handkerchief;

Fig. 5 is a view of the embroidered stitch on the other face of the handkerchief;

Fig. 6 is a view showing the method of finishing corners of a handkerchief;

Figs. 7 and 8 are views illustrating modifications of the invention; and

Fig. 9 is a view of a modification of the stitch.

The invention will be described as applied to handkerchiefs, which are scalloped and embroidered on all four sides. The blanks 1 for the handkerchiefs are cut to the proper size. Each edge 2 is notched at 3, as illus trated in Fig. 2. The notches, in this instance, are comparatively narrow V-notches.

The notched edges are then embroidered with a suitable stitch as shown clearly in Figs. l and 5. The looper thread is indicated at 4 and the needle thread is indicated at 5. This forms a narrow embroidered edge, in which the inner and outer lines are parallel with each other.

The scallops are formed by the lateral movement of the stitching mechanism under the control of a cam, or its equivalent, as the material is fed through the machine. in a straight line. The threads draw in the cut edge, which acts as a filler for the embroidered edge, producing a well defined scalloped edge, as shown clearly in Figs. 1 and 3.

In some instances, the notches may be narrow, as shown in Fig. 7, or they may be a wide V, as shown in Fig. 6, withoutdepart ing from the essential features of the invention.

When the embroidery of one edge is almost completed, a half scallop is formed, as shown at 6, after which the embroidery is continued in a straight line, as at 7. The handkerchief is then turned at right angles and a straight line of embroidery 8 is formed on the adjoining edge,- corresponding to the line 7, and a half scallop is formed, as at 9, after which full scallops are made until the opposite end of the handkerchief is reached, when the operation, above described, is repeated.

By this process, the four corners of a handkerchief are uniform.

By using two threads in making the stitch, the embroidered edge can be formed in one color, or in two colors, the looper thread being of one color and the needle thread being of another color. In some instances,

the stitches may be increased in length at the point where the scallops 'join, as shown in Fig. 9.

While my invention is especially adapted for scalloping the edges of handkerchiefs, it will be understood that it can be applied to other articles, such as napkins, towels, &c.,

without departing from the spirit of the invention.

Iclaim: V

The process herein described of embroid ering fabrics, said process consisting in feeding a blank in a straight path through an ei'nbroidering machine having an over-edge stitch-forming mechanism, notching the edge portion of the blank at intervals, and shift ing said stitch-forming mechanism laterally to form an embroidered scalloped edge .as

the blank passes through the machine, the

length of said stitches being equal, and the excess material being drawn in to form a filler for the embroidered edge.

RUDOLF oan.
