To @ZZ wftom it may concern Be it loir/wn thut L L iivmiwoe it. Sooners, o. citizen, et the United @totes und resident oli liest Cleveland, in the countyv ot Cuya-` tubrie bund which is einphiyerl in emistruct-V ing` the Subors laminated, cohesive, inter- 'Wound fabric9 described' in Letters Potent grunted to"hi1n on February 13, i912, ille. 120175271 und on March 26, i912, No. 17021:.0111; and is .itsellE constructed in preferably tubular torni und from laminated, cohesive, intcrwound, librous elements, in o similar meneer :intl afterward flattened to tornio tieltible bond. v

The fabric onnd is composed of series of brous elements luid or Wound in parallel, spaced rows, st o predetermined :inglea the rows of one series crossed by the rows of other series, itl series being laicl alternately in opp i te directionsy ami the spaces between the rows of one series being` substantially covered by the rows ofthe next luid parallel series. :in this manner' spaced openings are produced. throughout the fabric before the fabric hns been compressed. IThe tubular structure thus produced is then flat tened under grcsure and. the pressure forces the elements which lie over the spaces into them, until u smooth, laminated structure with selvagge edges is produced without openings of any sort. h

llhe present improvement is tlesigneetto provide, in addition to the fluid yadhesive materiel with 'which the librous elements are coated the fabric bond is being constructed upon the mandrel, continuous layer or bonds of solid rubber or other suitable uclhesive substance interposed between the series ot' elements described, and which muy be of any desired thickness, so that when the Specification of Letters Patent. TEQQQM-Qfl gilt? jgj,

tubular fabric has been compressed to form o bend the rubber will cover and enter the' previously mentioned spaces or openings and. will furnish o surface to which the elements in the series'which cross above and below the openings, will adhere. The several bands when completed Will also have the rubber filled spaces exposed at regular intervals upon their outer surfaces, trie result being that series ot such bonds Will uit here more firmly together when iiiterwound `with erich other to form a, fabric. rThis plo dures un unix/oven but homogeneous fabric' of predetermined extensibility and suitable for use in pneumatic tires or casings and for fire and oir brake hose or analogous tubing.

The invention` is illustrated in the accomn mini/ing drawings, and is hereinafter more ully described, end specically pointed out in the claims.

In these views A, A. represent the series of parallel spaced ybrous elements which :ire the first laid askv the bond is constructed by winding them spirelly upon e mandrel et a, predetermined angle. I

B, B represent e serios or spaced fibrous elements laid in the opposite direction, pretcrably ut the same ongle thereover. Upon these series is laid :i layer composed of bands orstripsoi' unvulconized rubber C, C, or other adhesive muteriulyund upon the rubber band fabric band.

are spirally wound series D and E, of fibrous elements corresponding to the series A and B, and respectively parallel thereto and so positioned as to cross and covery all the spaces or openings between the spaced.

fibrous elements of series A and B. These four series form the fibrous structure of the When the tubular occur at regular intervals throughout' the band in the diamond-shaped spaces C, C, formed between the brous elements and giving to the outside of the band a checkered or tessellated appearance.

In Fig. 7 is sh wn a transverse section of a band before being compressed, in which fabric elements and lwill bind the laminathat it is difficult to tear them apart, Aand thus a thoroughly 1 homogeneous product is formed. The bandv tions so closely together thus constructed has also a predetermined amount of extensibility, depending upon the angle at which the fibrous or yarn element-s are interwound and positioned in forming the band. In practice, after the adhesive binding material in the band has become `so lidilied to a'certain degree, when the liquids and gases have been evaporated from the fluid adhesive, the band can be stretched and will afterward remain elongated a certain amount, since the band, being of tubular construction, will tend to grow smaller and longer, but -owing to its flattened condition and since the layers are held together b'y the solidified binding material; it will elongate.

and become slightly narrower without unduly .stretching the yarns. TWhen incorporating these bands in a tubular fabric, the extensibility of the latter both in axial and diam Atrical directions may be governed both by vhe relative extensibility of the bands in the several layers of the fabric and also by the relative angular positions of the fabric bands in these several layers. The different layers of fabric in a tube constructv ed in this manner become practically a unit in resisting internal pressure.

dty is obvious that a centrally positioned strip of solid zulhesive-material may be used alone in theconstruction of' the fabric band, in addition to the fluid adhesive with which the 'severalv 7arns in each seriesV are coated or a partial o r integral layer of adhesive ternately bandl isflattened, asA seen in Figs/1 'and 2, the rubber layer will `spaced openings the inner openings in the two sides of such series may be introduced between any of the al` laid series of fibrous elements as-Y tliy are being interwound and laminated in constructing the fabric band, without departing from the spirit of the invention or the scope of the claims.

Itis obvious that a series of yarns or threads or fibrous elements of any desired material, or bands therefrom, may be used as the fibrous lelements in constructing 'the fabric band. It is also obvious that a mul-v tiplicity of series of fibrous elements withf or without a multiplicity of interposed layers of solid adhesive material may be used in conjunction`with a fluid adhesive Substance in constructing a laminated, cohesive fabric band of multiple layers.

Having described ythe invention, what claim as new and desire to secureby Letters Patent is:

1. A tubular, compressed fabric band comprising series of parallel, spaced, interwound, fibrous members, one series crossing the adjoining series at an angle to form between said members, four being incorporated in the band, and a layer of vulcanizable adhesive interposed between the first two and last two series of said members, saidopenings being opposite to each other on the inside of the' band, and the inner faces of the layer of ad- 95, hesive cohering together through said openings.

2. A fabric band comprising a series of spirally wound fibrous elements, laid in parallel spaced rows, each element composed of 10o substantially parallel yarns coated with arf;

fluid adhesive, a second series of spaced parwound thereon in the allel elements spirally crossing the said first opposite direction and lseries at an angle, a layer of solid adhesive v laid thereon, a third series of spaced yarn elements wound thereon parallel to said first series and covering the spaces between the elements of said first series, a fourth series wound thereon parallel to said second series and covering the spaces between the elements of the said .second series, the said band l flattened thereby providing selvage edges, and the opposite sides of the layer of adiresive cohering together through the openings formed between said series of yarn elements.

3. 1li-compressed fabric band comlibtbd .of I laminated,'interu'ound fibrous elements and having spaced openings interposed between said elements, and a continuous band of solidified adhesive material passing between said elements `and being deflected to fill said openings when said band is compressed. n
