This invention relates to elastic woven bandages such as are used for surgical pura protective selvage or edge. such bandages to a limb or other contoured member it is important that the application be symmetrical and applied under uniform tension. Y

The great problem has been to provide an edge or selvage such as Teuffel taught in his United States Letters Patent No. 889,827, granted in 1908. Such bandages have been wonderfully successful but there has been a marginal tensioning along the selvage by reason of which even the most skillful were unable to get smoothly laid and uniformly ten-k sioned bandaging. p Y

The present invention provides a dressing bandage with a strongly woven but elastic edge or selvage. By the use of warp threads which are over-twisted alternately to the left side and to the right side, such bandages are centrally elastic.

These dressing bandages during the application' of the bandage have to adjust to the form of the limb or part to be dressed to avoid a non-uniform stretching or tensioning of the warp threads over the width ofthe bandage.

In the bandaging of limbs or contoured parts of the body, therefore, the tension of the warp threads will increase or decrease respectively from one edge of the bandage to the other. This is especially true inthe case of dressings applied under considerable tension or dependence upon the elasticity of the dressing bandage, as the more strongly stressed or tensioned edge side influences the uniform elasticity of the total dressing and may have an undesired effect on the wound or part to which the bandage member is applied.

The purpose of this invention is to eliminate these disadvantages and this is effected by making a dressing bandage which is woven elastically by the use of warp threads which are over-twisted alternately to the right and left side with a firm edge but one which is kept more elastic at its edges.

As illustrative of my improvement I have 555,664,` and in'" Germany Januiary26', 19.31; i shown in the accompanying drawing rabandage in-accordance with my invention. j.,In

the drawing: suchabandage', and@ v A Fig. '2 is a. schematicl analysis of a simplev warp-and Woof analysis.

F ig, l isV afgeneral view ofafragment According-to previous practices as established-,byiDrfWilhelm Julius Teufel, the

bandage isV w'oveni, in 'suitable widths for bandagingp-:and-these arerrpreferably woven on the well known ribbon loom. 1 The alternate warp/threads,Av as indicated, in Fig.' 2, are vall twisted in one direction, while'the intermediate warp threads Bare ,all` twisted -in theopposite direction, y i

`The weftthread C was ledback and forth ,inV the ordinary manner, and carried-around the outermo'stwarp-threads, said weftthread .being`V preferablyA loosely` twisted., While s uchpbandages have many .points of excellence and advantage therewas in many cases .difficulty in getting4 a 'perfectly smooth application Las., above stated.` c Y f f i `A cording tomy,v invention I provide-in the edgeofV the bandage twoor-more marginal pairsof-warp Ithreads D, E and RG, side :by side and twisted in the same. direction to provide fora' balance of elasticity.

Thus,` inthe edge strips `or, selvage there aembdedsde by Side. two Warp-threads 5over-twisted in thesamegdirection simul.-

' taneously"bytheV weft threads.

Preferably, lthe plural similarly ltwisted warp threads of the selvage receive a lesser tension Aduring the weaving as comparedl with the warp threads of 'the remaining band. In such a bandage, theedges are thus given an increased elasticity and a soft yielding eect so that the bandage or dressing makes a good support and a uniform application at uniform tension.

Furthermore, the edges or selvage of the bandage being defined in the woven pattern, a uniformlydefined winding of the bandage is made possible.

As shown in the drawing, the warp threads A and B are alternately overtwisted to the right and left and are bound by the weft thread C. At the edges of thelhandage there are bound as a selvage two or more warp i threads D and E, which are overtwisted to the right Vand two or more warpV threads Fy and G overtwisted toward the left and bound by the weft thread C. I prefer to impart to the warp threads D, E and F, G, as compared with the warp threads A and B of the remaining bandage, a lesser pre-stretching` when weaving in yso that they are vmore softlyelasti'c. i This provides a d'elinite and nonraveling selvage but yet proportionately elastic.` This selvage may be and is charac- Y teristically defined by colored warp threads.'

thus making a distinguishing feature for the bandage. Y Y

What I thereforeclaim andv desire to se- 5 Vcure by Letters Patent is l. An elastic dressing ing central warp threads alternately over'- twisted right and left, and two or more warp threads adjacent each edge over-twisted inl the saine direction but of opposite twistv at the opposite edges of the bandage and included together inthe weft forming` selvage edges of the `bandage of than the ncenter warp.

'Y 2. An elastic dressing bandage comprising central warp threads alternately overtwisted 'Y right and left, and two or more warp threads A over-twisted inthe saine direction forming vselvage edges of the bandage of greater elasticitythan the center warp, and hound in the selvage alongside of each other simultaneouslyfby the weft threads said overtwisted warp threads in the opposite selvages be- 'ing reversely twisted.

` An elastic dressing bandage in accordance with claim l having the distinctive f'eature that'the similarly wound warp threads of the selvages have a lesser tension than the lother warp threads of the bandage. Y
