ME THOD 0F FORMING ROLLS 0F SHEETS OF PAPER OR OTHER FLEXIBLE MATERIAL' SPECIFICATION forming part of Letters Patent No. 789,707, dated May 16, 1905.

Application filed February 2'], 1904. Serial No. 195,555.

To all Irlmini! may concern..-

In the drawings, Figure 1 illustrates said Be it; known that I, CHARLES J. BELL-UH. 5 roll, showing said detachments of paper on a greatly-enlarged scale m tlnckness, o indicatia citizen of the United States of America, re-

siding in Springfield, in the county of ll'ampf I ments of paper occupying their relative poden and Commonwealth of Massachusetts,

have invented new and useful 1m norements in Methods of Forming ltollsof S ieets of Pa j I mg the relative positions occupied by them per or other Flexible Material, of which the following is a specification, reference being had to the accompanying drawings and char- 3 3 illustrates a simple apparatus adapted to aeters of reference marked thereon.

I arlous eliorts have been made to put up packages of sheets of flexible material, espedetachment in substant ally the order and clally paper, so that one sheet at a time may be detached. In no case, however, has a method been provided for forming a package or roll in detachments having no connecting means, so that one sheet at a time or two or more, as 'n'edetermined, maybe detached at. one operation or pull.

The object of my inyention is to provide a method by which such flexible material may be formed into a roll in detachments, so that succeeding detachments are wrapped upon preceding detaclnnents in such sequence and relation each to the others that when it is desired to feed the detachments one at a time in substantially the order and relation in which they were wound into the roll it, may be readily done. I accomplish the objects of my invention by the method herein described;

By the term detachment as herein employed it is to be understood that it refers to either one or more sheets of flexible material, so t-hat a fdotaelnnent as the term is herein employed may comprise one sheet, two, three, or more sheets.

In the drawings I illustrate on a greatlyenlarged scale ,a package of paper formed'aecording to my invention and also illustrate a method of forming such a package into a roll and also means for supporting such roll so that detachments m. be taken from said roll one at a time in substantially the same order and relation in which they were wound; showing in each instance a portionof the nextn'esenting detachment in position to be rea y gr'aspe ing a core, and 1 2 3 4. &c., indicating detachsition when in the roll, Fig. 2 is an edge 55 view of several of said detachments, illustratprovidcd they were nnrolled in a. flat formation and occupied an extended position. FF,

carry out the method of forming the roll so as to insure the independent feeding of each relation to other detacl'nnents in which they were wound, showing a portion of each succeeding detachment presented in a. position so that itmay be easily grasped after its predecessor has been fed oil. Fig. 4 illustrates a simple apparatus adapted to su )port the roll. Figs. 5, 6, 7, and S illustrate ill'erout methods of making up detachments as wound on or fed oil' from my roll.

In describing my roll it should be understood that by the term rear as a )plied to a sheet or detaclnnent- I desire to esignate the end thereof last to be wound upon and first to be i ed from the roll and that by the term lapping" as applied to-the relative positions of detachments I mean to indicate that; one of them rides upon the surface of the other. Bythetermsinneran( outer0r outside I mean to designate, respectively, a position toward the core or away from the core. By the terms preceding and sueeceding as applied to sheets and detachwound into the roll.

A detachment may obviously consist of a single sheet, as illustrated in Figs. 1, :2, 3, and 4, and a roll may be made up of a succession of detachments each made up of buta sin le sheet, so such sheets may be of irregn ar lengths orhave varied laps and projections to the. rear of each succeeding sheet in relation to the next preceding sheet, or the detachments may also comprise an additional sheet or any number of additional sheets superimsheet laps upon the outside of the next prei ceding detachmentand the rear of which said inner" sheet projects to the rear of said precedingdet achment, as

illustrated in Fig.5. 1

Fig. illustrates the make-up of a detachment tbe outer andinner sheets of which are approximately even with each other at front l and rear,

sheet the front end of which does not extend so far and whose rear end extends fart-her than the said supporting-sheets of the detachment.

Fig. 7 illustrates a detachment in which the middle sheet. is shorter than the inner outer. supporting or what might perhaps be calledv the binding sheets of the detachment, its rear end falling short of the rear ends of said supporting-sheets.

Fig. 8 illustrates the make-up of a detachment comprising three sheets each of different length, the rear ends. not being parallel.

()ther make-ups for the detaelnnents may be easily imagined which it ould be practical in roll formations coming within the scope of but between which is supp n'ted a z the next preceding and my invention, different varieties of detachments being especially useful for diverse puruntil in its due turn, detachment following oses.

The method in which the dot acln'nents are 5 wrapped, each succeeding detachment lapping upon the outs de of the next preceding 1;

and its rear projectingto the rear of the same preceding detachment, will be understood if we suppose the core placed upon the detachment as indicated in Fig. 2 and rolled toward the opposite end of the procession of lapping detachments, the detachments being rolled or wound upon the core as I thelatter is rolled along toward the said oppo- 1 site end of the procession of detachments. l Then it will be observed that each successive 1 detachment of flexible material will lap upon the outside of the one next preceding it. in order. and the rear end of the said succeeding detachment will project to the rear of the said next preceding detachment. hen such a roll is placed m a suitable apparatus, such as is causing an endless (heated. and the detachments of flexible material are presented thereto and to the increasing roll of material being wound thereon so as to catch in the bite of the tapes at predetermined intervals, according to the intervals which are required in the feed, hut

aiways taking care that each succeedingde- )Oll the outsideof and that its rear end shal project tothe rear of detachment. The fingers j and 1:, short and long, and the guide I assist in the formation of the roll.

In F igA is shown a simple apparatus which may be used as a holder for my roll formed as above indicated, the apparatus shown being much like that illustrated in Fig. 3 except that the fingers and the guide are omitted. In feeding the roll is caused to revoive in the reverse direction to that which it takes in windingeither by pulling upon the successively exposed ends of the detachments or by rotating the roll directly,or both. Thus the rear end of each detachment is successively brought out free of the bite of the tapes in substantially the order and the relative position which they took in winding, the end of no other detachment being presented tachment shall lap 11 detachment. in due order and relative posithat until the supply previously wound on the core is exhausted.

Ha ing therefore described my invention, what I claim isl. The method of forming a roll of flexible material in separate detachments which comprises the propelling of each succeeding detachment upon the exterior surface of the next preceding, before the latter is fully rolled, so that each succeeding detachment laps upon the rear edge of the next preceding, and causing said detachments to assume curricular form.

. 2. The method of forming a roll of flexible fabric in separate detachments, consisting in belt to travel under tension around a supporting member, and in l impelling into the bite formed between the shown in Fig.4,dulysupportingt lie aine,wliile' 1 allowing it to rotate as required to feedthesuccessivc detaclniicnts, they \\'Ill be presented and delivered as'said roll is caused to revolve 2 one at a time and in predetermined order and the relative position of lap and rear-end projection which they took in winding. Asimple apparatus for forming such rolls is trated in Fig. 3, comprising endless tapes 1', supported by rollers g, h, and i, one of which illusrollers, by preference the latter. is-held in yielding bearings, so as to ermit the endless i tapesj'to continually hold in partial embrace l a roll of varying size mounted in movable bearings. The core a of the roll is revolved by any convenient means in the direction intraveling belt and the supporting member one such detachment after another, each succeeding detachment lapping on that surface of the preceding which 15 adapted to be an exterior surface when caused to assume curvicular form.

3. A method of forming a compact roll of separate detachments of flexible material, consisting in feedingto a core partially inclosed by one or more tapes, a series of such detachments in such a manner that the forward edge of the succeeding detachment overlaps the rear edge of the preceding detachment thereby coming between it and the tape or tapes. 7

4. The method of forming a roll of sepamte detnchmems of flexible material which CMnpIlSPs the propelling of such detach ments .wm'azim upon a revolvjng member,

one following another before the preceding l5 fully rolled, so that each succeeding de- Kaclunenl laps upon the rear edge of the next preceding.
