To all whom it may conm:

Be it known that we Joerrii l. Kiurr, a i-liiwn of the United tates, and a resident ol' New York city. vounty and Stato of New lurk. and limito: E. lamioiirr, a citizen of the United Stutes,'und a resident of llrooklyii, in the coliiity of Kings and Stato of New York, have. invented certain new and useful Improvements in the Art of Mani mliitiug Paper or Similar lFabric in eb Forni, of which the following iii l. iipcuifiliation.

This invention rchtlee to the artof inanipulatiu paper or similar fabric iii web forni, an more particularly to feediugithe web to web-iuanipulatin machines having continuously moving cy indrioal web forwarding surfaces.

lleretofore rent dlllleultieii havo been'oxperlonved in iwiliii the web to machines of the choix ri'fert'oi to, und ca'iociully to.

those iiiiicliinv.- in which the wel orwiirdiug surfaces uniko unbroken iii-mure contact `with thc web und continuously o ioriito in auch contat-t, iis they do, for exuiup u, in the rotary hinoigriiphic printing nuu'hinv invented liy George E. lancoast and made the object of ii oopendio application for ii patent. tiled .la uiiry ttt, |000 Serial No. litl. 'Iho ilillli-.ii liisii ure miiiiily due lo the hielt of uniformity in the fnhi'ic as it comas from tho manufacturer. While the texture und condition of the fabric forming a. web are usually uniform len hwiuo of the web, they are almost universal v not uniform widthwiso of the web. For example, while tho weight oi' iliiiniuu'ss ol' the fuhrie foriuing ono side of ii oi-h ure uniform throughout the length ot" the web, they nro not the same us the, weight. or dampness ofthe fabthe crntraLpnrt ot the weh or the other 'side thereof. This results in un inequality in the length .of the wel nt d ifferent parts of ita width. which inequality periiirits und is iii-uiiilly iiliifonn throughout the'length of the web. This inequulily in thel lon 'th of thc weh nl, different. poi-ls ol' it uit tti. nei-timely interferes with tliie truvvl of the weh through the iuachinc, iii lhiit the extra materinl iii the longer parts of thu web tend to accumulate u advance of the web forwarding surfiic, with thc result thul, those {mi-ts of the weh tend tc gather into wrink es and pio-m through the machine in a wrinlrled condition. lf the inequalities in the different parte of the web are excessive, or if the web forwarding surfaces make unbroken premura contact, wrinkles will form and they are iipt to increai-e in iiiae and in extent until the feed of the weh is nllvieti'd throughout itii entire width.

The oh'ect of this invention is to provide u meth whereby there dilleultioa in the iiiiinipulatioii of u web ma boevcrrome. We hiive found lhiit ii defective web may be smoothly fed to and paneed through o machine having cylindrical web forwarding surfaces by iio varying the tenaion or the length of thc manipulated part of the web locally with relation to ita width aa to comienaate for or remove the in ualitiea in the eiigth of thoaaid part of the web at ditlerent parte of ita width. 1t unnilly happenin that the irre laritieain the fabric of' the web widtliwise thereof, and the reaultant inequalities in the I en h of the web at diereut parts of its widt i, vary more or lesa imifornily from one eide of the web to the other, so that if the web were luid out evenly on a plano nui-face it would not extend in a straight line but in the aro of a circle the degree o! the curvature ol' which would deieud ou the width of the web und the dif- -renee in the length of the two aides thereof. When it iti attempted lo feed such a web by ii pnir of eyliiidi-ii-iil rollers iii the ordinary wuy, the web tends to cree J hileriilly out of its ath to the rollers, un if thia ia prevented, t ie long aide of the web tenda to un'uiuuhite in advance of the rollers nud iur-'ii through theni in the forni of wrinkles. Ve hiivi' found tluit auch ii web iuay be fed evenly through the rollers by viii'yinf the tension on the two sides of the web. f the tension on the short side of the web is inode greater than thnt on tho longer side of the web, the .-.hoi't aideof the wol will he :di lilly i'eturdcd so that it will not nnss throng,r i the rolh'iii u font itx-i the loni`r idc of the web und, if thi'. tenhion on the two :tides is properly ndjuated. tho dill'creiiiir iu the apn-d nt which the two nido of tho wi'h triiwl through the rollers in runde i-qiuil to thtl dil'- {ereuce in thc length of the two sides. This retiirdution of the weh due to the iniieuse iu tension thereof may be due to u slight slipiiiiir of the rollers upon the web, oi' it muy lie due tothe fact that tho web is stretched a however, that the i te For example, one or both ed .be longer or shorter than t'lie centralA Y pzrtioii thereof, or there may lie lz increasing the p t f in any siiitab as The longe: parts of the web may be shortsled by t application of heat to those Iscanbsincreasedlocally le ndtly or.- temporarily, li

Where inequalities in the of the web at dilsrsnt prts of its w h are excessive, any or all of the above i of manipulating the web may be .combined to etlect the desired result.

For the purpose of more clearly explaining the practice of our invention, reference et is .made to the drawings annexed hereto and forming a part hereof, which illustrate a form of apparatus adapted to carry out our invention.
