Tn Il 10111111@ if mw 1/ ruimer/1,:
Be it known that I, Fununnick J. Mo'rz, a citizen of thel United States, and a resident of the city of New York, borough of .\Ianhattan, in the county and State of New York, have invented ncwand useful Improvements in the y Art of and Machine for Making Perforated Paper. of which the following is a full, clear, and exact description.
r1`his invention relates to a new method of making perforated paper. lt is particularly intended to produce. the perforated sheets used in musical instruments; but it is useful in other connections. IIeretofore these perforations have been made by cutting or punching them in the paper, which involves a loss of paper, an extra expenditure of time and labor, and also materially weakens the sheets.
)Iy invention comprehends forming openings in the paper stock while the same is vet in pulp-like form, and subserpientl y t-he stock thus oriliced is converted into paper, producing die perforated sheet referred to. In connect'on with this improvement it will be observed that the perforations are formed during the very formation of the paper and without any additional expenditure ot' time or labor. and there is an actual saving rather than a waste of stock, and further and quite as important is the fact that by this process the tibcrs ot' thc pulp adapt themselves to a large extent to the form of the perforations and assume positions lengthwise of the edges of the pcrforations., thus greatly increasing the strength of the perforated paper as compared with that of the paper which is cut or stamped to produce the perform-ions.
The invention also relates to a machine for' carrying out my improvement in the art. This machine mayl be of various of the known types of paper-making |nacliines-for instance, the Fourdriniermachineoracylinder-machine. I prefer, however, to adopt a Fourdrinier machine. and in doing this the wire is provided with a number of protuberances around which the plastic paper-pulp 1s spread, so that when -i the pulp is couched the pcrforations are retained and made permanent as the paper-making operation is completed. In order to facili- E tate the removal of the pulp from the wire, the
protuberances are made elastic, and at a certain point along tbe path of the wire these protuberances are cxpandc land then allowed to E retract, thus` separating their walls from the E pulp and allowing the pulp to be easily removed from the wire.
IY will now give as an example of my invention a speeilic description of one embodiment of the machine and one manner of practicingT the art. i
Reference is to be had to the accompanying drawings, forming a part of this specification. in which similareliaracters of reference indicate correspt'nuling parts in both views.
Figurei is a plan view showing a Fourdri- I nier wise equipped for carrying out my process and illust-rating the pulp spread thereon; and Fig. 2 is a vertical section of the same, this view also illustrating the compressingrolls, the function of which will hereinafter appear.
)I y improvement may be practiced with the aid of paper-making apparatus of various sorts. In the drawings I haveshown part of a Fourdrinier machine modified accordingr to my invention. 'lo do this, the Fourdrinicr wire a has a number of protuberanccs earried on its upper or active face and arranged according to the order or pattern which it is desired that the perforated paper shall take.
- These protuberances will vary in shape according to the shape of the orifices to he produced, and they are preferably formed of soft rubber suitably fastened to the wire. The paper stock or pulp is spread over the wire, as indicated at e in Fig. 1, the pulp lying around the protubcrances and said protubevances forming in the pulp-orlices corresponding in size and arrangement to the protuberances. The pulp is then carried by the wire on through the other operations of the Fourdrinier machine, and the pulp is thereby converted into paper in which the orifices formed by tile i)rotuberances` are faithfully retained. It will also be observed that as the pulp is advanced on the wire the agitation of the pulp, due to the characteristic movement of the wire, causes the fibers of the pulp to settle around the protulmrances and to assume positions lengthwise of the side walls of the protuberances, and consequently of the orifices formed thereby, thusi greatly increasing the strength of the perforated paper as compared with that of the paper which is cut or stamped to produce the perforations'. ln order to enable the pulp t0 be readily removed from the wire and disoriv gaged from the protuberances thereof, I i construct the protuberanccs of soft rubber, as explained, or some other yielding material, and at a point on the frame of the Fourdrinier machine intermediate the last suctionbox and the couch-roll l vlocate two rollers e and ff'. '.lhesc rollers are suitably mounted on the l `ourdriuier frame, so that the wire a, with the pulp, passes between the rollers, i and by proper adjustment of the rollers the elastic protuberanecs will be compressed, thus increasing their thickness, and thereby widening out the perforatious in the stock formed by the protuberances. This upon the retraction of the protuberances detaehes the stock from the side walls of the protuberances and prevents the pulp from adhering tothe protuberanccs when the pulp is taken from the wire. Fig. l shows at the point c' the pulp in thc position it assumes when iirst placed on the screen, andthe shaded portion c' shows the condition of the pulp after having passed between the rollers whereat the protuberances are spread out, so as to enlarge the perforations and separate their walls from .the sides of the protuberances.
llavingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. The improvement in the art of produc ing perforated paper, which consists in the following successive acts, to wit., first, in disposing plastic paper pulp or stock around a p1 otuberance in a sheet the thickness of which is not more than equal to that of the protuberance to forni an opening through the pulp, and, second, in separating the pulp from the protuberance and converting the pulp into paper withoutclosing the opening formed by said protuberance.
2. rlhe improvement in the artV of producing perforated paper, which consists in the following successive acts, to Wit, first, in disposing plastic paper stock or pulp around a protuberance to form an opening in the pulp, second, in enlarging said protubcrance and permitting it to retract, to detach its sides from the adjacent pulp, and, third, in separatingthe pulp from the protuberance and converting the pulp into paper without closing the opening formed by said protuberance.
3. r[he improvement in the art of producing perforated paper, which consists in the following successive acts, to wit, lirst, in disposing plastic paper stoel: or pulp around a protuberance in a sheet the thickness of which is not more than equalto that of the protuberance to form an opening through the pulp, second, in agitating the pulp to cause the fibers to range lengthwise alongside of the protuberanc'e, and,-tl1ird, in separating the pulp from the protubcrance and converting the pulp into paper without closing the op'ening formed by the protuberanee.
