To all 'whom it may concern:

Be --it known that I, JOSEPH IMCLANE, a -citizen of the United. States, residing) at 'Washingtom in the: District of Clum ia,-

have inventedcertain new'and useful Imvprovements in `a'. Weftless Tire-Forming Cord Band, of which the following isa specification.

This invention relate-s to a Vform of .textile- `for the production-of` a weftless Acloth for use articularly designed for the enstructon'o the (carcass ofppneumatc tire casings andof the general type known as cord tires. In this pe of tire the distinguishing characteris-- tlc-has been to retain ,aI weft weave only for the purpose of temporarilyv holding the cords or warps parallel. and in sheet formation', and are used-in Vgreater or less num-l ber, the resence of' which inthe manufactured ru berized cloth causes `-lack of uni- Y, formity an insuiiicientl tension and-'undulations of thev cords, imperfect'coating of the cords' with rubberA with consequent weak spots and separation ofthe rubber from the cords, besides producing a source of frictional heat and other objectionable features in the tire built of this form of weft c ord cloth. The object therefore of the present invention is to eliminate the weft threads from f the rubberized cloth vand avoid all the consequent disadvantages due to' thepresence of weft threads in tires, aswell as the saving of the cost `of the weft threads and the' weaving cost thereof, and the making of a form of weftless cord bandsthat can be.

hand-tying. operation required in beaming a 'large number of cords, while at the same time la form o f cord band is produced suitable for :ictioning directly through thev 5 Yrolls of a calendar by reason of the means by which the cords yare heldin `their proper parallel and. equally stressed condition in theon the'beam and theA u ncords terminating at' oneend in a ilexible winding portion preferablyof fabric weave ,form end fabric tedious ,-to provide a Iiexibleiheader, for beginning the on the beam, and at its other end w1th a similar` flexible winding portion for'startlng the v,winds on the usual wind-up roll, 4so that all the cords will be maintained accuratelyv spaced' and no undue yskill or time requiredl in the operation of beamingorA installing a beam and connecting the band with its wind-u roll in readiness vfor drawing the same. through the calender.

lIn thefbeaming of these'eord bands with their terminal fabric ends, the cords will pass from their spools through a vlool'n that' will b operated to weave. a portion of'L-the' bands only where the fabric ends are desired and for the purposeof beaming short ban lengths of 1501yards or other commerclal. l"

' length, theY terminal'fabridportions may be Imade by intermediate weaving of the bands il' and the cutting' through the same to divide the fabricA portion and form'fabric end por-y tions." i

The presentinvention is specially dsigned for use in connection with the special method of apparatus forming the subject of Van alplication lliledfof even date here- Y.

Y Figure `1 illustrates the weitless 'corda' band having the terminal fabric ends, `and Figure-Q'illustrates a len h of band to be cut into several lenV s by cutting through the intermediate abric weaving to A portions for ,the shorter lengths;

Referring to the drawings,v 10 indicates 'the cords ofthe weftless 'band' and Y11 the fabric terminal portion of the band'. Except for these termlnal portions the c'ords are free of any cross support, but under the f winding and spacin initiated. by the fabric fend portions and t e equal tension resulting from the umform stress of-the wound' woven portion asl an attaching and draW- ing Ymeansthese free cords are maintained in their sheetformatiomvso that in calendering or in impregnating they will not be caused to overlapV each other. or form -1n the rubberized cloth what are known as vhard' and soft spots but produce a uniformproduct. lV-henV it is desirable to form'the short' Ico' llio

lengths for convenient shipping to and use by the trade the intermediate fabric portions 11 are made and cut through on the line a/-a to form end fabric portions for the shorter lengths.

It Will be seen that by this form of cord band a product'is finished that, both from the textile' producing end and the use thereof in forming Weftless rubber cloth, presents many economies and advantages, and with the further results that a superior tire may be constructed therefrom and at less cost and labor.

What I claim, is:

1. A textile article of manufacture for ythe continuous production of Weftless rubberized cloth therefrom during the passage of the same through suitable rubber-applying means, said article comprising a multiplicity of cords or Warps arranged in parallel relation to form a Weftless band of relatively great length and terminating in Woven sections at each end adapted to provide means for maintaining the cords or Warps in flat parallel 4relation and furnish a Wind-'up portion upon which the cords of the unwoven length of the band are wound in parallel relation and maintained in such relation in the winding.

2. A textile article of manufacturefor the continuous production `of Weftless rubberized cloth therefrom during the passage of the same through suitable rubber-applying means, said article comprising a multiplicity of cords or Warps arranged in parallel relation to form a Weftless Wound band thereof of relatively great length terminating in a transverse Woven portion at one end and connecting the cords or Warps in flat parallel relation and adapted to provide a Wind-up portion for. the initial Winding of the band, and a terminal transverse portion connecting the cords or Warps together in band-formation at the other end, whereby the cords or bands in being unWound and rewound Will travel during the application ofthe rubber in uniform band formation.

3. The method of forming a band of parallel cords of relatively great length for the' continuous production of Weftless rubber cloth therefrom by suitable rubberapplying means during the passage of the band of cords therethrough, Which method consists in first Weaving the cords to form a fabric section for connecting them in their parallel band formation, Winding thev cords in such formation upon the fabric section, Weaving at intermediate points of the band of cords other woven sections, to form therebetween a band section of the cords of relatively great length, and cutting through the intermediate Woven sections to form the commercial lengths of the band with a fabric Wind-up section at each end thereof, as and for the purpose set forth.

In testimony whereof I afx my signa- JosEPH A. MCLANE.
