A FIRM.

ELASTIC FABRIC.

To all whom it may concern:

Be it known that I, 'WAIJDEMAR Kors, a citizen of theUnited States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Elastic Fabrics, of which the following is a specification.

strands at their bent ends. I

In carrying out my inventionI provide a flat strip-1 elastic fabric or Webbing, preferably parallel sided and invwhich the elastic strands are in line with the weft threads and intermediate of the margins or selvage,

- with the return ends as loops engaged or caught by independent or extra threads as warps laid therein, which extra threads follow the outline of the elastic meYnber.

In the drawings, Figure 1 is a plan illustrating part of a length of fabric or webbing, according to my invention. Fig. 2 is a cross section thereof and Fig. 3 is a cross section-illustrating a form of my invention.

Similar numerals and letters of reference indicate the same parts in the drawing.

The" edges or selvage are shown at 2 and 3, and a and b are the marginal inelastic or sewing sections, 0 represents the elastic sections, 4 the elastic strands which are laid back and forth across the elasticfsections c and 5 and 6 are .the extra threads iaswarps of increased area around which the end loops formed of the elastic strand are passed in laying the same back and'forth across the elastic section.

The webbing of my improvement is formed with warp threads 7 and with weft threads 8. It is immaterial, according to my invention, Whether the elastic strands 4 are woven under tension or not, but whatever tension may exist is at all times under control, or whether the usual weft threads 7 pass clear across the fabric from selvage to selvage or not. It is also immaterial whether the elastic sections 0 are parallel sided, or. gradually dive Specification of Letters Patent. Application filed September 30, 1911. Serial No. 652,164.

rging and converg-' 'ing, as shown in Fig.

Patented ma 2, 1912.

g The marginal inelastic sewing sections ab are formed of the warp threads 7 and weft threads 8.

The elastic sections a may be composed ,of the warp threads 7 and elastic strands 4 which are laid back and forth through the warp threads for a predetermined portion of the fabric or webbing, and I may also weave the fabric or webbing with the cotton weft threads running from selvage to sel-' vage. I may also apply appreciable tension to the elastic strands during the movement of the shuttle in the weaving operation, and

this tension is at all times under control and iscreated by devices associated with the' shuttle.

The elastic fabric or webbing as woven with the elastic strand thereof laid back. and forth across the elastic section, produces bent or return ends of the elastic strands at the margins'of the elastic section, and in this connection I provide the extra threads 5 and 6 as warps. These threads are preferably of increased area .in cross-section.

They are laid into the fabric in the weaving with the loops of the elastic strands 4 place around the same, and these threads are in the fabric or webbing or embedded in the surface of the same. They serve to prevent theelasticstrands from pulling into or through the webbing, and these extra threads constitute the margin or outline of the elastic sections whether the same be parallel sided as shown, or diverging and converging, as shown in Fig. 1.

In Figs. 1 and 2 the extra threads 5 and 6 as warps are shown mainly over or embedded in the surface of the fabric, while in the section Fig. 3 these threads are illustrated as in the fabric, that is, woven in and directly forming a part of the fabric. These threads 5 and 6 are put in as separate warps and graduated as to their diversions preferably by fan-shaped reeds or by a jacquard device.

I claim as my invention: 7

1. An elastic fabric or webbing having marginal inelastic or sewing sections and an intermediate elastic section in which latter the elastic strands are laid back and forth 'ble longitudinal threads of suitable character passing through the loopsof the elastic strands for holding or anchoring the respective open ends of the elastic strands independent of the usual warp or Weftthreads of'the Webbing.- e

2. An elastic fabric or Webbing having marginal inelastic or sewing sections and an intermediate elastic section in which latter the elastic strands are laid-back and forth parallel with the Weft threads and at right angles to the warp threads, and extra threads as warps running parallel with the margins of the elastic section and around which the elastic strands as loops pass at their bent or returned. ends as the same extend back and forth across the elastic section.

3. An elastic fabric or Webbing having an elastic section in which the elastic strands are laid back and forth with bent or return ends and marginal threads of increased area around which the said bent or return ends pass.

Signed by me this 22nd day of September 1911.
