Application led January 12, 1925. Serial No. 1,864.

My invention relates to the art ot manufacturing pneumatic tire casiiigs and more particularly to a method oi preparing 'fabric to be used in building the carcass Ot such casings. rElie Yfabric used for this purpose is either square Woven, or so called cord or Weitless cord fabric., herein generically termed labiic which has been calendered oicther- Wise rubberized. The 'fabric ai'ter calendering is rolled in a liner oit duck or other suitable material. From this rubberized web, strips ot desired Width are cut, the cut being usually on the bias, in other words so that the strain resisting elements lay an angleto the lengt-h of the cut strip. According` to prior practice the strips of fabric as they are severed are laid by hand into'a liner which is rolled up and from which tl moved as required to be formed into bands or spliced into lengths as the type of building machine may require. l

rlhe old method Oi' severing and handling the fabric stripscr plies require a relatively large number ot Operators to emove the fabric from the bias cutter, lay it smoothly in the liner and ivind it into'rolls.` The rubberized fabric is sticky and dilicult tohandle and at the speed at Wliichthev cutting machine is necessarily run Wrinkles and folds occur in the cut plies even when care is used by the operators which cause delay and Waste when the fabric is later remove-d from the li. ers.

lt is among the Objects Oiimy inver ion to provide a method of cutting the fabric which will decrease the number oi" Operators atthe,`

cutting machine and permit the fabric to be mechanically Wound into the liners, to prevent the occi'lrreuces Ot toldsand Wrinkles and toV decrease the an'iount oi' liner material required. Other and further objects will ap pear'i'irom the .llc/Wing specification and claim.

ln the irate one embodiment ot my invention- Figure l is a diagraniii'iatic side clef. 'Lion cans ttor carrying Outiny method,

' r 2 shows a portion cli a fabric web ing to my invention, and

section ot treated .iei'iing ally a. roll et rubberized 'fab ic a Wound in' a suitable liner 5. machine is indicated at 2 and means for Winding up the treated tabricin the liner is shown iiey are later ieinpanying drawings which illus;

A conventional bia-s 'cuttingr at 3. In carrying .out my methodl set tl knives of the cutter yso that 'while the fabric itself is substantially severed the rubber coating on one sine reinainsintact an'dretains the strips in connected relation as indicated at G in Figures 2 and 3. In the latter Figure the fabric is shown at 4, the vcoatings'of rubber being indicated at 8.

Referring again to Figure l thev fabric as it leaves the roll l is drawn forward and thru the cutting machine. The liner 5 p'asses'beneath the cutter' to the Windup mechanism 3 Where it again meets the now partially severed ot ivrinllesjand Jfolds yoccurring at the'edgcs.

and ends as is the case when lthe strips are separated and separately placed in the liners. When the strips are to be used thetreated roll of Yfabric is placed in a suitable .supply rack and unwound, the strips .being easily sepa rated from the Web' as indicated at 7 in`Fig ure 2.

Having described one embodiment ot my inventionl` claim: l Y

The method of'cutting and handling a relatively Wide'web vot tireinatcrial, iormed of tire fabric bonded between two layers of rub- .y

ber, which comprises 'forming successive cuts crosswise off the Web and through the upper layer oi rubber and the. fabric Without` ruptingthe underlying layer ot rabbi... vline of said cuts being on the bias with respect to the length of the web, and Winding the so cut web into 'i cut diagon f llyk positioned sections entering the lincrroll first, Without tendency to disrupt the'uncut layer oit rubber and Without pie senting transverse severed edges, to 'torni a uniform compact roll in which, the tire ine-.terial is substantially coextensive with it: tecting liner. n

ln testimony Whercot I have signed iiiy name tothe above specification.
