Specification of Letters Patent.

Patented Feb. v13, 1912-.

Application filed December 31, 1910. Serial No. 600,313.l

To all whom t may concern.'

Be it known that I, LAWRENCE A. SUBERS,

a citizen of the United States, and resident/ nated-cohesive interwound fabric can be constructed such as described in my former ap- No. 540,982 led January 3l, 1910.

The essential features of novelty contained in this invention are a flattened band originally of cylindrical form, said band composed of groups of loose lying parallel yarns or threads cohering together, this bafn'd being coated on the exterior surface and also thoroughly saturated throughout the interior with preferably vulcanizable liquid rubber cement or any other suitable adhesive material. These loose lying parallel yarns or threads are wound as a unit on spools or tubes without being twisted together and the yarns may be used in anypredetermined number in each band, and the tubular band made therefrom will be'of correspondingly predetermined diameter before flattening. This collapsed band has therefore selvage edges, is strong and flexible and when incorporated in a fabric or when used as a Yfabric in itself will not ravel or permit of the separate threads being unwound or separated in any manner under rough usage' and hence assists greatly in prolonging theflife of the fabric and increasing 'its utility and efficiency in daily use. VThe band can be made of any desired width forincorporation in a laminated, such bands interwound and` 'cohering together. .l

The invention is illustrated in the accompanying drawings, hereinafter further described, and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of oneside of the completedband showing the coating removed; Fig. 1 is a view of a group of loose lying parallel yarns or threads; Fig. 2 is v.a side'elevation nated a pneumatic tire showing) unwoven fabric composed. ofl

of Fig. 1 showing the coating stripped from a portion thereof; Fig. 3 is a transverse secf tion thereof enlarged; Fig. 4 is a transverse section of a forming tube and pressure rolls, illustrating the manner of flattening the tubular form of the fabric band and of saturating the fabric bandwith Vfluid rubber; Fig. 5 is an isometricperspective View and illustrates themanner of forming a lami- `unwoven fabric from interwound bands of this character; Fig. 6 isfa plan view of a portion of the saine fabric after completion; Fg.6a is a perspective Viewv of thethreads of a Vfabric. band showing manner of formation; Figs. 7 and `8 represent plan views of portions of the band enlarged Q' showing the threads running at various angles'. for reasons hereinafter' described. Fig. 9 1s a broken side elevation of a `portion of hose pipe formed of the improved bands,-

illustrating thestrengthy and durability of exposed parts; Fig. l0`is a side elevation of 'I fabric formedin the same manner as the andi;, Fig. llis a transverse section thereof. i

As shown in Figs. 1, 2, 3, and -4 the bandyis composed of seriesof groups of close lying parallel yarns or threads. These groups :of threads are applied upon aformer D (shown c in Fig. 4') in such avmanner that they are laid in parallel spacedrows, first in rows running in one. direction and then in rows running at an angle thereto,.followed by rows parallel/to the first and second laid rows. The spaced threads of the'outer rows are compressedto ll the spaces betweenthe I parallel rows beneath, the result being an unwoven laminated band of tubular' form,

-in two layers. The fabric l.formed therefrom is similarly constructed as shown in Fi 5,

which will serve also as an illustration o the structure of the bandbut not of the mode' of kflattening or vof applying rubber thereto.

InFigLh, 1, l and 1,.1, are parallel? bands, running in one direction, and 2,2, 2, and 2', 2', 2, are parallel bands running in --another direction. When compressed theV parallel bands 1 .will come to the same level bet-Ween the'other bands l5 andthe bands2 between the b ands'2 anda practically twoI ply "fabric Awill result.V c

'The bands are formedof threads B laid in precisely the same manner asthe fabric, l

and this constructionis shownjin Fig.- 6,v`

3, 3,3, being. parallel threads inthe` upper row '3,'3, Sthelower'rows parallel therevcal or collapsed form as ma with. fl, l, .4, are the rows of threads crossing the first named rows and 4;', 4, d are the rows parallel therewith. The bands having been completed in a former F in a dry state in a tubular form are then pulled from the former, `and attened between rollers such as E, E in Fig. 4.

The band is simultaneously saturated with rubber. rlhis is accomplished in the most thorough manner by injecting the rubber through the former where the pressure of the flattening rollers forces it'into the band until it permeates every 4part thereof between the yarns, and coats the yarns and threads in a thorough manner.

The flattening of the tubular band results in the formation of a band such as shown in Fig. 3 of great flexibility and strength and an outer rubber coating G is then applied in any convenient manner or it may be coated while being constructed into a fabric if desired.

It will be seen by reference tol Figs. 7 and 8 that the band can be made inra similar manner of any desired width and one set or rows of the component threads in one band may be laid at an angle relative to the Vother set or rows making it possible to make bands which vary in elasticity, which will be controlled by the angle of the threads. @n this account a fabric can be made as shown in Fig. 9 having one layer X formed of such bands of a given degree of elasticity and having other layers Y and Z of different degrees of elasticity and hence the difference in expansibility due to difference in diameter of the several layers can be overcome and a hose can be formed of several layers which will have the same rat-io of bursting limit,

and a stronger fabric will be constructed thereby.

The advantages of a flat band of' this character and its adaptability for use in the construction of fabrics for various uses is therefore very great.

It is obvious that these bands can be made multiple by adding successive layerswof this fabric over one another and that an inner lining may be incorporated within this fabric band the whole retained in a cylindribe desired without departing from the spirit of invention or scope of the claims.

It is also obvious that this \fabric band may be formed of any predetermined width and of any predetermined thickness from groups of close lying parallel yarns or vthreads and may Joe used as fabric of itself if so 'desired without departing from the spirit of the invention or the scopevof the claims. y

It is also obvious that any suitable material fabric or otherwise may be formed or laid partially around the mandrel and thereby be incorporated within this fabric bandv during the formation of the same.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

l. As an article of manufacture, a band for incorporation in a fabric, comprising, a

flattened tube composed of unwoven interwound groups of close lying parallel yarns or threads, arranged in parallel rows, and the sidesof the tube compressed together to -form selvage edges, the said band saturated with fluid rubber or other adhesive material.

2. A band for incorporation in a fabric, comprising, a tubular struct-ure composed of threads formed from groupsv of close lying parallel yarns or threads, said groups of threads laid in spaced parallel rows at predetermined angles crossed by spaced groups of threads laid at predetermined angles' thereto, a row of said spaced groups of threads filling the spaces between the rows of groups of threads parallel therewith, the sides o-f said tube being flat-tened together and saturated with fluid rubber or other ad hesive material and an exterior coating on said band.

3. In a constituent element for an interwound fabric, in which the elements cohere together and are interlaid, al flattened tube, composed of unwoven flattened threads interwound and `interlaid withv each other, each thread composed of a parallel series of yarns, the finished product saturated with fluid adhesive material, and provided with an external coating of the same.

4. As an article of manufacture, an element from which a fabric can be constructed, said element comprising a flattened tube composed of unwoven nterwound and interlaid flattened threads, compressed together, each thread composed of la vseries of parallel yarns loosely associated together,

said flattened band saturated throughout `and between the yarns with fluid rubber, or other adhesive material.
