FULLER, DECEASED, ASSIGNORS TO TOMPKINS, HAW- LEY, FULLER COMPANY, OF VALATIE, NEW YORK, A. CORPORATION OF OREGON METHOD OF ANE MACHINE FOR MAKING PAPER Application filed May 5, 1927. Serial No. 188,966.
The present invention aims to enable paper to be manufactured with fewer and simpler steps and machinery, particularly by el1m1- mating the use-of press rolls with then attendant expensive clothing and the large amount of power required to operate them, as well as their tendency to crush and weaken the paper sheets and cause sheet breakage Another object of the machine is to faclhtate the making of plain, glazed, creped or with only slight changes or adjustments.
Further objects and advantages of the invention will be in part obvious and in part specifically pointed out in the description hereinafter contained which taken in conjunction with the accompanying drawing, discloses a machine by the use of which paper may be made in accordance with the invention. In the drawing- The single figure is a diagrammatic side view of the main parts of a machine adapted to operate in accordance with the invention.
The invention is illustrated as applied to a machine of the Fourdrinier type, having a head-box 1 from which the pulp flows on to a". forming member 2, having the usual tension devices, breast roll 3 and couch roll 4, the width of the pulp course being regulated by the usual deckle-straps 5.
As the newly formed paper web'travels along the forming wire 2, a felt apron 6 is caused to overlie and travel along a section of the forming wire in such manner that the web is supported between the two. We have found that a sufficient amount of water may be extracted'from the web at the above sta e of its manufacture, to enable theweb to led directly therefrom to the driers, meaning by directly? that no press rolls need be in terposed between the forming wire and the drying section of the machine. As shown a plurality of suction devices 7, which may be wardly on to the felt apron from suitable blast pipes 8, the blasts giving added activity to the movement of the water or'moisture in its process of extraction and also serving to absorb a certain amount of water in passing through the unpressed paper web. Each air blast with its accompanying suction box may remove about the same amount of water from the uncompressed sheet as would be removed by a pair of press rolls, whereby it becomes possible to take the sheet directly from the forming wire without passing-between press rolls or being otherwise subjected to mechanical pressure except the relatively light pressure of the couch rolls, to the drying section of the machine. As shown the felt apron 6 carries the paper web along past the guide rolls 9 and 10 to adjustable pressure rolls 11 and 12 which press the felt and the paper web against the periphery of the first roll 13 of the drier section of the machine. We prefer to locate the roll 11 below the center of roll 13 and the roll 12 above the center thereof, as
shown in the drawing. The roll 13 usually An adjustable scraping-board 16 also may be employed which acts to loosen up an foreign particles from the working'sid e of the felt apron. A suction box 17 may also be employed to loosen foreign particles from the exposed surfaces of the felt apron 6, after which the latter passes down around a guide roll 18 into contact with the newly formed paper web on the forming wire.
In the manufacture of a paper sheet as above outlined, the extraction of the neces sary amount of water prior to the drying operation is accomplished entirely by the suction devices 7 and the air blast issuing from of pressure to the web and the pressure'may' be heavy enough to produce a glaze if desired.
Either or both of the rolls 11 and 12 further-' more may be provided with raised surfaces to produce any desired marks or figures on the paper web.
If it is desired to produce creped paper, the paper web may be permitted to pass around roll 13 until it is creped by the action of a blunt-edged scraper 19, the degree of crepe being proportional to the bluntness of the edge of the scraper.
lln creping the drying rolls 14 will be slowed down so as not to stretch the crepe and the roll 13 will be heated to give the creping a better permanent set.
While the invention has been described as carried out by the use of a specific apparatus, it will be obvious that many changes may be made therein without departing from its essentials as set forth in the following claims.
We claim:
