METHOD OF MAKING A FLAT FIBROUS WEB.
application filed December 1, 1921. Serial No. 519,265.v
To all whom it may concern:
Be it known that I, ENPEI NisHrNA, a subject of the Emperor of Japan, residing at No. 833 Oaza nakameguro, Meguro-mura, Ebara-gun,Tokyo-fu, Japan, have invented certain new and useful Improvements in a Method of Making a Flat Fibrous e-b, of which the following is a specification.
The present invention relates to a method of causing fibrous substance mixed with any suitable adhesive material to adhere and solidify by projecting it by suitable means out of spouts upon the surface of a slowly moving wire gauze, felt, cloth or such like fabric. thus the fibrous substance forming a continuous film; and the object thereof is to obtain a simple method of solidifying the ulp of fibrous-substance so as to form a fiat fibrous web. i
The invention is clearly illustrated in the accompanying drawing which shows in elevation and partly in section an apparatus for carrying out the method Referring more particularly to the drawing there is provided a tank 1 which contains pulp suspended in a liquid containing any suitable sizing material. The liquid in the tank 1 flows downthrough a pipe 2 and a dischar e spout 3, provided with an ad ustable va vs 4 by which lbs.,
flow of the fluid is regulated. Just below the discharge spout 3, there is a nozzle 5 through which is blown out air coming from a pipe 6 and having a pressure of not less than 2,000 lbs, say 5,000 per square inch. The compressed air will atomize the pulp containing liquid flowing from the spout 3 and will pro ect it on the surface of an endless belt 9. That part ofthe belt at'which the pulp is tobe projected is supported by a roller 8 which is covered by a sucking device 7 which is connected with a sucklng pump through a. leading pipe pump sucks oif liquid which is forced through the endless belt. The paper sheet thus formed on the surface of the endless belt is then taken over another endless belt 11 which travels over rollers 12 and is 13. There is over the nozzle a cover 14 and a fan 15 which blows away the air which has been deflected by the belt.
" Thelfollowing is an example of the manner of carrying this invention into practice.
Upon the surface of wire gauze vertically ;by the force with After (not shown) (16). The suckingthe air and the remaining dried by a drying drum' moved by any suitable device. project pasty mixed with sizing material and pigment outof spouts mider a. strong pressure. Then, the pulp will adhere to the wire gauze, and at the same time the superfluous water contained in the substance will be squeezed out which it is projected. drying or half drying, the substance is taken off from the wire gauze and is flattened apd calendered with rolls so as to form a continuous and smooth film or pasteboard. a
The projected pulp, instead of being rolled, may be pressed into moulds in wet state to produce various articles of papier mach; or sometimes felt, cotton cloth or the like may be used as the ground on which fibrous substance is projected, and the fibrous substance may be left adhering thereto, the fabric used as the ground then serving as a reinforcing material.
cases care must be taken to select kinds of fibrous substances and binding materials suitable for the different purposes according to the case.
The chief feature of the present invention thus" consist-s in projecting fibrous substance out' of spouts under a strong pressure upon the surface of some slow moving wire gauze, and 1n causing felt, cotton cloth or the like, the substance to adhere to the surface thereof, forming a continuous film.
The specific structure for forming a web is covered in my copending application Ser. No. 57 6,11 1, filed July 19, 1922, now Patent No. 1,519,696 granted Dec. 16, 1924.
Claims.
1. A method of making a fiat fibrous web, consisting in treating a fibrous substance with a sizing material and projecting the mixture toward a porous surface, forcing air under high pressure against the projected mixture to atomize the mixture and deposit the same on the porous surface, and simultaneously moving the surface as the mixture is projected thereon to effect the formation of an even film.
2. A. method of making a. flat fibrous web consisting in'projeoting a mixture of fibrous substance and sizing material under high pressure to atomize the same and cause it to adhere to a porous surface, simultaneously moving the surface to effect an even coating or film during the projecting of the material,
removing the film thus formed from the surface and finally performing finishing operations thereon, substantially as and for the purposes set forth. a
3. A method of making a flat fibrous Web consisting in treating a fibrous material with a sizing material and projecting the same under high pressure upon a porous surface so that the solid portions Will adhere to the surface and the liquid portions will be carriedv through the surface, simultaneously moving the surface duringthe projecting of the mixture to cause an even film -to be formed on the surface, removing the film thus formed, and finally performing finishing operations on the film, substantially as and for the purposes set forth.
4. A- method of making a flat fibrous web consisting in treating a fibrous material with a sizing material and projecting the mixture under high pressure upon a surface of porous material to cause the fibrous material to adhere to the porous material and the excess liquid portions of the mixture to be carried through the porous material, simultaneously moving the porous material during the projecting of the fibrous mixture to effect the formation of an even film on the porous material, performing finishing operations upon the film and porous material, substantially as and for the purposes set forth.
