ELASTIC WOVEN FABRIC AND METHOD OF WEAVING- IT.

Application filed August 19, 1921. Serial No. 493,649.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, ALFRED LAURAIN, a.

citizen of the'French Republic, residing at 86 A to 90 RueNotre Dame de Nazareth, city of Paris, France, have invented new and useful Improvements in Elastic Woven Fabrics and Methods of WVeaving Them (for which I filed an application in France, dated Sep-- tember 8, 1913, Patent No. 473,146, and in Great Britain, dated July 5, 1920, Patent No. 146,468), of which the following is a specification.

This invention has reference to improvements in elastic woven fabrics, ribbons or bands and in the methods used for weaving them.

The main object of this invention is to produce an elastic fabric, ribbon or band which is more pliant and moresupple and possess other important advantages as compared with such fabrics as heretofore made.

An important use to which this improved fabric, ribbon or band may be put is to be made up into braces, garters, hose sup- 25 porters, body belts and similar articles in which event this invention will obviate serious defects inherent in such articles when made from fabric as heretofore woven in that the latter exert a pressure on the whole surface over which they are stretched and further there is very little or no ventilation of that part of the body on which the article is being worn. This invention consists in an elastic fabric, ribbon or band that is formed with trans verse parallel ribs or ridges which project on'both sides of the fabric, ribbon or band, the said ribs or ridges being arranged in series spaced apart so as to leave short lengths of fabric between them, which latter may be plain ribbed or brocaded. The series of ribs or ridges may be spaced apart at regular or irregular intervals.

. The parallel transverse ribs referred to which stand out in relief on the two faces of the plain ribbed or brocaded fabric, ribbon or band form transverse channels betwen them for the circulation of air and they alone formthe contacting surfaces with the body.

Such a band of more or less elastic fabric is rendered very pliable or supple longitudinally by reason of the ribs or ridges and in a measure forms a pliant ventilated cushion which will not irritate the skin and has, therefore, a great advantage from the hygienic point of view.

The accompanying drawing represents the ordinary appearance of the extra supple new textile and the designing, enabling any specialist to mount and manufacture a type of this textile article.

Fig. 1 represents a plan view and the corresponding edge View of a piece of ribbon of this new tissue; a indicates the part in plain ribbed or brocaded elastic tissue and b the extra supple part with transverse ribs or ridges c which project on both sides. The parts a and b may be of variable lengths.

Fig. 2 is a plan view of the threading; 1 is the elastic rubber thread; 2, 3, 4, 5 are the ordinary non-elastic threads of the ground.

Figs. 3 and 4 represent a designing which comprises: a first piece, Fig. 3, showing the production of the plain ribbed or brocaded part a in one or several colours which may be in any required design and a second piece, Fig. 4, showing the production of the extra supple part b provided on its two faces with rectilinear parallel transverse ribs or ridges.

In Fig. 3, the designing of the first piece only represents four throws or passages of the weft, that is to say, the round, but it is understood that these four throws can be repeated as often as required, according as more or less great length is to be given to the part a of the tissue.

In Fig. 4 the designing of the second piece comprises two parts A and B which here each represent eight throws or passages of the weft; however, it must be clearly understood that each part may comprise a multiple of four when greater length is required in the part Z) of the extra supple The first piece Fig. 3, is made as foll0ws:-

At the first throw of weft, the Warp threads" corresponding with the ' combe'r boards 3 and 4 lift, whilst 1, 2, 5 descend.

At the hd threw, th W t-p; hr e e corresponding with'the comber boards 1, 3, 5 lift whilst 2 and 4 descend,

hat I a claim and desire to secure by Letters Patent is:-
