SURFACING PAPER.
Specification of Letters Patent.
Application filed March 9, 191%. Serial No. 823.359.
To all whom it may concern:
Be it known that I Gnoncn H. PARKS, a citizen of the United tates, residing at and whose post-oflice address is Glens Falls, county of Warren, State of New York, have invented certain new and useful Improvements in Surfacing Paper; and I do hereby elimination of the difficulty known in the art as flufing of the paper surface. So also, the treatment incident to the practice of the invention, permits the paper upon reaching the calender from the paper machine to calender more uniformly and with less liability to wrinkling or cockling as it passes through the calender stack, and with the generation of less frictional electricity than is usually produced at the stack. Moreover, in practice, it is found that the snapping off of the paper at the stack, andthe production of hard and soft streaks in the rolled paper are of less frequent occurrence, and that, with the employment of the steam heated calender rolls in the relationship hereinafter set forth, the paper possesses more stretch than the customary product,-the invention permitting the paper to be efiectively calendered at a pressure less than ordinarily used on a calender stack. H
In the accompanying drawings,-- Figure 1 represents, in part diagrammatically a suitable arrangement for putting the invention into practice; Fig. 2 represents an calender stack, part1 broken away, provided with a shiftab e roller, constituting one of the elements of the invention; and
Fig. 3 represents, partly broken away, a side elevation of the calender and shiftable end elevation of a roller shown in Fig. 2.
at of the series. This is preferred, in
but it will, of course, be understood ,that the paper sheet or web may be delivered from any other roll of the paper machine, according to the particular type of paper machine employed. 6 indicates the customary canvas web of the aper machine.
On leaving the rier roll a of the paper machine, the paper web, which is indicated by c in the drawing is at a temperature of from 160 Fahr. to 200 Fahr. In passing to the rolls of the calender A, the web .is carried over one and under the other of two rollers cl, e, which come in contact, respectively, with opposite sides of thepapcr on its way to the calender stack. The rollers (l, e, are water-cooled, and, for this purpose may conveniently consist of a cylindrical shell of say one-quarter of an inch in thickness and closed ends provided with hollow trunnion's, through which a continuous stream of cooling water is passed. The term erature of the water is such as to cause a eposit of moisture upon the surface of the rollers 03, e, from any source of moisture that may be provided, adequate for the purpose. Thus, for uniformity and regularity of deposit of the moisture upon the calender surface of the roll, it will be suitable and preferable to locate alongside of each of the rollers (Z, a, a pipe 7, supplying through a longitudinal slot a body of steam of low pressure and temperature, or a body of moi ture-laden air, so that on coming in contact with the periphery of the rollers, moisture within a suitable outer pipe it, whose function is to convey any such dripping to a suitable point of discharge. This outer pipe will, in general, not be necessary for the steam, pipe below the paper web a for the reason that any drippm from that steam pipe would fall clear of tlie paper. Both of the rollers 61, e, are idlers, and the roller (Z, may be the usual spring roll, familiar to the paper machine art, and will have for its function to keep the paper web at the proper tension and to deliver it uniformly and without wrinkles to the calender.
The bearings for the roller 6 may be either stationary, as assumed in Fig. l, or may be shiftable, as shown in Figs. 2 and 3. They are preferably shiftable, as shown in said Figs. 2 and 3, so as to enable the operator'to move the roller away from its normal position into a position where it will be out of the way whenever it is desired to enter the paper web c into the pass of the steam heated rolls at either initially, or at any other later stage in the operation. Thus, should the paper web break, which is a not unusual occurrence in the making and calendering of paper, it is customary tor the operator to seize the broken end of the web, in the space between the paper machine and the calender stack and to quickly throw said end into the appropriate pass of the calender rolls, and the roller 6 is made shittable in order that it may not interfere with this operation, or with the like operation when the end of the paper web is introduced into the calender rolls when the paper is first de-Y livered from the paper-making machine.
A suitable arrangement for shifting the roller e may consist, for instance, as shown in Figs. 2 and 3, in shifting it downwardly. To this end, the bearings n for the roller are held firmly between the straps Z: and a. strap 3 having two wooden blocks .5" bolted to same at the ends, which slide-freely up and down on the sides or the calender frames. These shittable straps are connect ed by sprocket chains 1? to counter-weights r. The sprocket chains t engage with sprocket wheels to on the shaft to, and the shaft in is provided with a sprocket wheel 2 operated by a sprocket chain g which engages a sprocket wheel 1 mounted upon a stub shaft, which carries a turn-wheel 1 within easy access by the operator; so that, by means of the turn-wheel r, he may lower the roller e out of the way, when desired.
The paper, in practice, usually leaves the roller (Z at a temperature or about Fahin, and passes the roller 6 at about the same temperature, this temperature being sometimes raised slightly by the accumulation of steam in the angle between the periphery of the roller 6 and the underside of the paper. The moisture which has been deposited on the periphery of the rollers (Z, c, is carried, by the revolution of said rollers into contact with the opposite sides or faces of the paper web, and is applied thereto with relatively light pressure,that is to say, with the light pressure of the spring roll (Z, and with the like pressure due to the change of angle of the paper web in passing over the roller c. The paper web, traveling at the usual high rate of speed, say from 500 to 600 ft. per minute, traverses the space between the roller (Z and the calender stack, which space is on the average about 8 to 10 feet, in a correspondingly brief interval of time, and at once enters the calender, as indicated, finally issuing from the lower pass thereof. The rolls m, m of the calender are hollow and are steam heated, to a temperature of about I naeneae 200 18. They constitute, in substance, heated ironing rolls for the surface-dampened paper web and the finished paper finally issues from the lowermost pass of the calender stack, with the uniform soft surface finish desired. The remaining rolls of the calender stack other than the rolls mare of the usual solid construction customary in paper mill calenders, and may be of any suitable number and size appropriate to the kind and quality of stock treated, as, for instance, newspaper stock, manila stock, or the like.
Thepaper stock will contain the custon'r ary amount of sizing. The amount of mel ture collected upon the rollers (Z, c, and applied to the paper will be sutficiently moderate to produce, in conjunction with the sizing, the skin finish contemplated, without weakening the paper web, and the ironing eltcct due to the action of the heated rolls m, will so far strengthen the paper that a notably less amount of pressure will be necessary in the calender stack than that usually employed.
lii so far as I am aware, it is broadly new. in the manufacture of paper, to impart a soft glaze thereto, by moistening the paper surface, as described, and then subjecting; the paper surface to the action of heated rollers, which exercise an ironing eficct upon it, in conjunction with a calendering action. In some instances, according to the type of paper machine employed, that is to say, according to whether the web is delivered to the calender stack from a lower roll of the paper-making machine or from an upper roll thereof, the said upper roll or the said lower roll, as the case may be may itself be cooled by water, or otherwise, and used, in conjunction with a steam spray, to receive a precipitation of moisture upon its surface and to apply the moisture to the correspond ing surface of the paper web, in manner similar to that of the roller (1 or the roller 6.
So also it will be understood that the use of the invention is not limited to the locatinp; of the rollers (Z, 0, between the paper machine and the calender stack. Thus, they may be located, for instance, in the space between the paper reel and a super-calender, plate-r, or other type of machine used for surfacing paper. Furthermore, one of the rollers (Z, 6, may be used without the other, whenever, for any reason, it is considered desirable to provide but one surface of the paper web with the proposed finish.
The term ironing, as employed herein, is intended to define the operation produced by the upper rolls of the calender stack, when heated to about 200 1 Having thus described my invention, what I claim is l. The method of imparting a soft surface glaze to a web of paper, on both sides 7 face gloss to a web memes of said Web, which consists in condensing moisture upon the periphery of a cooled roller, rolling said moisture with light tension-roll pressure into and upon one side of the paper web, condensing moisture upon the periphery of another roller and rolling said moisture with light tension-roll pressure into and upon-the other surface of the paper at a point in advance of the first roller, ironing the moistened paper web at a temperature higher than that of its moistened surfaces, and finally calendering the web after such ironing.
