Specification of Letters Patent.

Application filed November ac, 1913. Serial Ito. t02,1tt.

To all whom it may concern Be it known that l, SoLoMoN R. Waco, a citizen of the United States, residing at Appleton, in the county of Out'agamie and State of Wisconsin, have invented new and useful Improvements in Paper-Making Apparatus, of which the following is a specification.

The present invention has reference to lo paper-making apparatus, and more especially to apparatus for reeling or winding up the web of paper after the same has been passed through the. size bath and before it is subjected to the final drying.

lit comprehends the provision of improved devices for regulating the speed of the winder proper relative to that of the size rolls, for varying the tension exerted upon the web during winding, and, above an all, for smoothing out and removing .all wrinkles, creases, puckers and-the like in the web prior to winding. d

An embodiment of the invention is illustrated in the accompanying drawing,

whereof Figure 1 is a diagrammatic side elevation of the complete apparatus; Fig. 2 is an enlarged side elevation of the winding mechanism; Fig. 3 isa planview of Fig. 2; and to Fig. 4 is a transverse section on line H,

- Fig. 3.

lln said drawing, 1 indicates, generally, the strip or web of paper undergoing treatment. and 2 the bath of size through which the to same is passed as the initial step of such treatment. This web or strip, which has previously been subjected to the usual, preliminary sizing, with or without mordants, may be led to the starch loath either dito rectly from the machine, or after it has first been reeled up in a dry state.

Un leaving the size bath, the web is passed between the rolls 3 and 4t, which remove the excess size therefrom, whence it isled, while still wet, first over a guide r0115, and, next, under a relatively large drum 6, the latter being in the form of a smooth, polished copper cylinder and serving to initially smooth the web and to prepare it for subsequent so wet winding. The several rolls and the drum may be mounted in any desired manner, as will be understood.

From the aforesaid drum, the web passes, successively, to the improved take-up,

smoothing, and winding devices or mechanisms, the one first mentioned being constructed with the special object of preventing breakage, relieving shocks and absorbing slack, as well as of insuringrotation of the size rolls and the hereinafter-described winding drum 7 in unison. in the construction illustrated, this take-up or tension device consists of a yieldingly-mounted roll 8 and a horizontally-arranged, rising-andfalling dance roll 9. Roll 8 is carried by a pair of blocks 10, upon which the journal brackets 11 for its trunnions are fixed, and these blocks, in turn, are slidably supported upon a pair of parallel, horizontal rods 12 that pass loosely through transverse openings formed in the blocks, the rear ends of the rods being fastened to a cross-bar 13 supported by inclined brackets 14 from the drum stands 15. The front portions of the rods 12 are encircled by expansible coil springs 16 that are interposed between blocks 10 and the headed rod ends 17, the arrangement being such, therefore, that the said blocks 10, and with them, the roll 8, are normally pressed toward drum 6 by the action of the springs, but are free to move forward, against this pressure, when the tension upon the web increases to a given point.

As shown in Fig. 2, the web, on leaving the drum 6, passes upwardly over the roll 8, and thence downwardly beneath and aroundthe rising-and-falling roll 9, whose Patented nee. a, rare. I

trunnions are mounted in vertical slots 18 formed in a frame 19. From roll 9, the web passes over the smoothing device, subsequently described, to the drum 7, and then to a reel 20, whereon it is finally wound, while still wet. The drum 7 is "rotated through the agency of a cone or other suitable drive 21, capable of operating the drum at difl'erent desired speeds, and, in consequence, exerts a positive traction upon the web, which traction or pull is rendered ap proximately constant by the rolls 8 and 9. These two rolls have a cooperative or complemental action upon the web, the former moving forward and backward toward and from frame 19, and the latter moving up ward and downward in said frame, any sudden increase in such traction causing an upward movement of roll 9 which is neutralized by the rearward movement of roll 8 produced automatically by the spring 16.

too

Thus the two rolls work oppositely, and, in their action, serve to insure a continuous, regular feed movement of the web, devoid of shocks.

The smoothing device is-located intermediate the winding drum 7 and the frame 19, as previously stated, and in its preferred form, herein depicted, it embodies a pair of rolls 22 and 23, which are mounted. upon a cross-bar 24 supported from said frame by brackets 25. This bar is inclined upwardly and forwardly toward said drum, as" best shown in Fig. 2, and its upper or front longiy are j ourna-led in a the paper, while still drawn,

tudinal edge is disposed in close proximity thereto, while the rolls themselves are arranged at an obtuse angle to each other upon the bar, the apex of such angle being likewise directed toward the drum. The outer ends of the said rolls are j ournaled in brackets 26 fastened upon the end portions of bar 25, and their inner or confronting ends common, centrally-located bracket '27.

By reason of the angular arrangement of the rolls, the web, in passing thereacross, will be stretched and spread transversely, and 1n this way all straight Wrinkles and puckers in the web will be smoothed out. The action of the spreader is supplemented by means of the winding drum, which is so constructed as to provide for elimination of fine'puckers and wrinkles due to the presence of air or of air bubbles under the web. To this end the'peripheral wall of the drum is formed with perforations or openings 28, of suitable size and having any desired relative arrangement, and these openings, during the passage of the web thereover, break up the bubbles and permit the air to be issipated.

The afore-mentioned reel 20 is removably supported .in brackets 29, attached to the drum stand 30, so as to permit it to be withwhen filled, and deposited with the web in a wet state thereon upon a frame or rack 31, where it is allowed to remain for a period varying from one to twelve hours, during which step the roll of paper is subjected to a very extended and gradual permeation by the size. In consequence, the tensile strength as well as the ink-resisting property of the paper are increased. The roll is kept wet during this period of rest by being wrapped with wet cloths 32, Or in any other desired manner.

After resting in the manner just described. wet, is unreeled and passed over a series of drying rolls 33. It will be understood, therefore, that this final drying does not take place until the period of rest has been completed, during which period the size, continues to soak into and be absorbed by the paper, and for this reason the heating and drying are sufliciently .i-emote from the time of immersion in the size bath to work any injury upon the paper. The rolls 33 are steam heated in any. desired manner, and in this connection it may be stated that the continued soaking to which the paper has been subjected precludes possibility of its being injured during drying. This is a matter of especial importance, from an economical standpoint at. least, since steam may be utilized as a heating medium, or in other words, a steam drier may be installed, at a very much lower cost than an air drying system, and moreover, the sized paper is rendered proof against ordinary high temperatures by reason of its having been previously subjected to the soaking step or period of rest.

The afore-mentioned frame 31 whereon the wet roll of paper is allowed to rest may be of any suitable construction, but is preferably sufficiently large to enable a number of rolls to be supported thereon at the same time. Also, the rolls may he moved in order through this frame, the paper on the roll at one end of the frame being unrceled and led over the drylng rolls. The roll at the other end of the frame is that one which has just been removed from its support in the winding mechanism, it being replaced by the previously emptied reel from the first-mentioned end of-the frame.
