of Iowa, haveinvented certain new'and useful Improvements in Paper Manufacture, of which the following is a. specification.

rThis invention relates to an improved paper manufacture, andy an object of my present improvement is to manufacture paper intober#strandsv especially adapted for use iiii'naking absorbents of that class in which the mass of fiber composing the same is so constituted and organized as to provide active absorptive' qualities combined with efficient distributive qualities.

It will be remembered that in using some kinds of absorptive materials, suoli fori instance, as fine vegetable Yfibers massed together, suoli as cotton or linen fiber, for instance, there is a marked tendency in many cases, especiallywliere the iiuids to be absorbed are of a slightly pasty .or albuminous character or of a coagulative nature for the thicker components of the iiuid to form a coating over the exterior'mass of the fiber and so prevent the efficient operation of the fiber as an absorbent for the more flfid portions of the substance to be absorbed.

One of the objects, therefore, of my presentV improvement is to minimize those objections, and these I accomplish in the/present instance by manufacturing'suitable and relatively fine ibcrs into relatively larger fiber like bodies or fiber-strands" and by mingling these together either by theii'iselv es or mixed with another and preferably iinei' liber component, totlieieby obtaina highly active absorbent quality while maintaining the mass of the whole sufficiently open in its texture or composition to provide for the necessary. free Vlistribution between such larger strands of which the mass is coinposed. One

relates to the reinforcement of the manufactured 'liber-strand in such a manner that each filierestrand will-be self sustaining and resist compression and matt/mg" when the mass is subjected to the action of fluid. 'This maybe produced by soiiieadhesivc sub-v stance, which in practice may be in the.. na-

ture of a glue or cement-like material rela-V tively Anonesoliilile iii watcij'icarricd byy one surface of 'the fiber-strands.

' iber sheet or by the application thereto ci some suitable reinforcing substance telfort/ed.A

feature of my present improvement rllie reinforc-- v ing either by treatment of the surface of the by the subsequent dividing up of titesiieet into ber-strands of proper sisesaiid pe 'and the curved formation'of these,' added to the curly and spiral formation which may be vgiven them in the dividing or severing operation will give the mass a self sustaining quality `enabling it toresist compression and also lto resist action of the liuids' received by 'it having a tendency 'tof cause trie mass to mat together'. v

Drawings illustrating my present improvement accompany `this specification, 'and wherein i i Figure l illustrates in perspective' heet of material prepared for the productioeof the fiber-strands ;.,this view is on. an enlarged scale. f Fig. 2 is sectional view of a'portioii of such sheet of material and is shown in still furtherenlargement; Ifig. 3 illustrates in plane view a sheet of materiali and a form of knife in horizontal section, thelriiidieis shown ashaviiig made the first out in severing the sheet into a number of 'liber-strands. Fig. l is a view similar to Fig. 2 showing the knife after it has made its seeond'cut and wherein it has produced a number of'iberstrands. Fig. 5 is a perspective viewo'f one of the fiber-strands, This is shown in an enlarged manner 'for the purpose of elearness. Fig. 6 illustrates the feeding movement; and Fig 7 shows a mass of the fiber strands.

Y The absorptive elements e'ii'ibodiediii the present improvement are each composed of a .plurality of what are frequently designated fibers, and is made up into a body .jhich from its length and iiarrowness might "-be designated a strand and which liaveilierein designated a iibenstrand, 'althourli in some aspects it would not' be strictly' ce led a strand. l

A feature of my improvement relates'to 'the construction of the4 iiber-strand, as '10, F ig. 5, of a form deviating substantially from a straight line, and'lii'i some cases -curled'into a spiral formation so as to provide for a lesser I actual quantity of material wheiitl'ie' fiberstrands are promiscuously massed together in a form suitable for applicationas .anab- 's-o'rptive material. In Fig. iis illustrated,

in a'soiiie'what enlarged view, suoli e nia-ss4 prepared in slieetforin, but, of compe, it will be understood that the material 'maybe made in ribbon -orvin rope e orniation,

v forced or otherwise shaped finto `body or v tine nature and adapted to pac together closely for many of the purposes for which such materials are employed, and having the vio y character. These ne Iibers, indicate advantage of low cost cleanliness and freedom of admixture witi materials of an unfavorable character. In connection with this material I prefer to employ for the finer qualities of the sheet form absorbents Aa moderate admixture of cotton or linen fibers, or some other vegetable 'fiber of yanale ous b 3() in F ig. 2, being relatively long, and ifwell distributed throughout the mass assistin holding the short wood fibers, indicated by in Fig` 2, together during the preparation of the same into sheet form. preparatory to converting this sheet material into my improved absorptive fiber-strands. In practice a small percentage of vegetable ber, as for instance one to two per cent. by weightv maybe employed. The sheet material havinor been prepared in this4 or any other' suity abile manner I then, in practice, a ply the reninforcing material in the form of a layer spread or suitably applied to one side of said sheet material, and after the reinforcing may terial is sufficiently seasoned or dried, as the case may be, Iprepare the sheet material so treated 0r reinforced into fiber-strands by cutting 0r otherwise dividing the same. For this purpose I may employ especial apparatus designed therefor, and which forms the subject-matter of a copending application, filed January 13 1906, Serial No. 295,907.

The sheet of material made insome suitable mannerfromthe wood fiber, or the wood fiber suitably mixed with the vegetable fibers for binding it together, and design ated herein in a general way by 15, is shown as having applied to one surface thereof a coating 16, which may be of some suitable stiflening material as above alluded to, it will preferably be such as will vadhere merely to the surface of the sheet of fibrous material, and will not permeate the same to any great extent, since should it do so it would occupy the interstices of the which should be left open for the more fluid portions of the/material for absorption. The stippling 17 is for the purpose oi" designating one manner in which the twc bodies, the fibrous sheet and the reinforcing material, may adhere together.

In Fig. 4. and 5 a manner shown in which the sheet may be divided up into a scvries oi fiber-strands, the knife blade designated by 18 in Fig. 3 which is represented as sinuous is shown' having descended into the sheet 19 and cut oil' an end 20; this of course is the lirst position. In vFig.. 4 the @races knife is shown as having made afsecond descent, and the sheet 19 is shown as having been advanced forward and sidewise so that the line of cutting will come in such a position. that a number of bodies 21 willbe severed from the stock. Each of these bodies is shown as being wider at the central portion 22 and tapering down toward the ends 23, which in the present instance are shown as attenuated to points. These bodies whencut and considered irrespective of the curl incident to the shearing action are of a curved or analogous form, and may be of an ogee formation. The knife will preferably coperate with some other knife and produce shearing cuts, and in such shearing, assuming that the cutting commences at one end of the strips, the strips will curlr upon themselves. In some forms of knives which may be-used, the surface of the sheet which is toward thedirectionv of the descending knife will curl upon the outer side of the liberstrand 19. In the present illustration the stifening material is shown uppermost, and 'in the illustration in Fig. 5 such stiifening material is shown upon the outer surface of the liber-strand. If, however, it is desired to have the absorbent material upon the outer side and the stiifening materialupon the innerside the ibrous portion of the sheet will be presented to the shearing knife; the

various re uirements of practice. 1

It is pre terable that the cutting be carried on in such a manner that the cut edges are left clean and free from projecting fibers or from fuzz or dust of tom libers, since advantages accrue from having each ber-strand present an-unobstructed.surface, thus providing for a highly efiicient absorptive qualcurl can thus be readily controlled to suit the ity over a large area of surface, while at the same time preventing obstruction by the vfuzzy material of the distribution spaces within the mass of material, and more particularly at the orifices of the interstices at the surfaces of the liber-strands, cess ol' producing these iiberstrands is made the subject of `my copending application filed January 18, 1996, Serial No. 295,909.

In Fig. 7 anl absorptive mass 4U is illustrated made upof a quantity of iiber-strands l() and vegetable fibers 45, such for instance as cotton or linen intermingled with the fiberstrands and binding these together, and somewhat assisting in the distributive and retentive qualities of the mass.

An absorptive mass must not only be such as will readily take up within itself a quantity of material for absorption, but must be capable ol retaining the material so received', and must not pack down and mat together upon the application of fluid, or upon the application ol' fluid combined with such pres- The prov sure as the mass will be subjected to in thc A use to which it may be applied.

such uses.
