It is the experience of paper manufacof novelty will be pointed out in the appendedturers that owing to the directional quality of claims. c these irregularities parallel to the length of the In the drawings: web, such irregularities, when the paper is wound Fig. 1 is a plan view of one end of the paper upon a roll, exert a cumulative eil'ect which he roll and its shaft together with a gearing for said 10 quently attains such proportions as todistort or shaft adapted for oscillation and embodying a stretch the paper and render the rolls unsatisfacpreferred form of the invention. tory for various uses including web printing 7 2 is a view in vertical sectional elevation presses. In order to prevent this it is the practice taken on the broken line 2-2 of Fig; 1;

to wind the rolls looser than is to be desired; and Fig. 3 is a view in vertical section taken on the 15 as a result of this it not infrequently happens line 3-3- of Fig. 1; that the layers of the roll slide on one another Fig. 4 is a view in perspective, schematic in during handlingor shipment,.,amatter which is character, showing an arrangement of the undisadvanta'geous and results in injury to the winding and winding rolls and of the trimmers papen for the web disposed betweensaid rolls. 20

My invention seeks to overcome this difllcuity In a preferred embodiment of the invention, and is predicated upon the discovery that the the reference character Ii designates a web of above mentioned defects may be entirely elimipaper which is being unwound from a roll R hated and a smooth, tightly wound roll had by thereof mounted upon a shaft I! which extends oscillating the paper during the winding operainto and is supp rt d at ne d y a aring 25 tion slightly in its own plane and transversely of l3, collars l4 and Na being secured by set-screws its direction of travel, thereby preventing the upon the shaft l2 for the purpose of locating the irregularities in width from building up in the roll R of the paper with respect to the finished roll. According to one way of practicing the infoil (R The roll is held upon the shaft in vention, the paper, after leaving the paper makthe usual manner by means of a sleeve it at each ing machine (which may be of any known type as end.

To accomplish this, block l6 slides in 'a dove- 35 trimmers of a fixed distance apart, whereupon tail groove its in head II, as best shown in Fig. the web so trimmed is wound into the final roll, To produce this motion a spindle 2i having the trimmers being located at a distance from threaded engagement with the block I 6 is mount- 4 the adjacent edges which is slightly greater than ed in lugs 22-43 of the head ll, so that by turn- 40 the amount of the oscillation. Alternatively, the 8 the Screw nut 25 th bearing will be moved 40 may be received on an oscillating winding transversely of the axis of the roll. Provision is roll in the machine and the unevenness produced had -s the m an axial on the ends of the rolls removed in the rewinding rectum, and this is accomplished by mounting and trimming operationa the head ll in a dovetail guide I! and causing It is therefore a principal object of the invenit have an adjusted by means. of 45 mm to provide for the purpose described means the spindle 21 having threaded engagement with 8. lug 29 of said head i1, said spindle being jourfor oscillating the paper web during the finishing naled in lugs a of a carnage I! so that this operation desirably in combination with means adjustment is accomplished by turning the for trimming the same and winding the trimmed knurled nut 26 My present invention relates to an improved method and apparatus for winding paper. In

the operation of the Fourdrinier machine, minute I irregularities in thickness exist having'a direcweb onto a roll.

.A further object is to provide an improved mounting for the unwinding roll, permitting an accurate adjustment both longitudinally and V transversely of said roll whereby the unwinding roll may be accurately lined up in respect of the. winding roll.

Various advantages of the invention and other objects to be attained will-be apparent in the The arrangement provided for osc ating the shaft in a longitudinal direction will now be described, it being understood that such means is illustrative merely and that various other mechanical devices might be employed for accomplishing the same purpose. A shaft 30 is mounted in bearings 3| carried by rails 20 between which an eccentric 32, fixed on the shaft 30, turns in a yoke 33 which depends from the carriage IS, the operative relationship of the eccentric 32 and yoke 33 being best seen in Fig. 3, from which it is evident that the continuous rotation of the eccentric flcauses the carriage l9 and the parts carried thereby to oscillate in a direction parallel to the axis of the roll. Carriage i9 is held against upward displacement from the rails 20 by means of the gib plates I90: engaging the under side of said rails. I

A preferred means of actuating the shaft 30 comprises an electric motor 35 of constant speed type which drives said shaft through a speed reduction box 38, a shaft 36 in alignment with shaft 30 and a flexible coupling 31 Joining said shafts, the motor and speed reduction box being secured to the base B of the apparatus by means of bolts 40.

. As shown in Fig. 4, the web'wfleaving the oscillating roll R passes over idlers I'I" and thence to rotary cutters 4243 which operate against supporting rolls 45 and are driven by means not shown. The portions of the roll so trimmed oif are indicated at 48, 49. The cutters 4243 are disposed at a fixed distance apart and also from the adjacent edges of theweb by an amount slightly greater than the amount of the oscillation whereby the oscillation of the web in its own plane causes the thickness of the trim to vary by the amount of such oscillation, producing a trimmed sheet of fixed width, which sheet is then wound onto the roll B by means of the driven rolls 50, 5| supporting said roll B In this manner the roll B may be tightly wound and because of the now stepped relation of the minute irregularities in thickness of the sheet, the roll presents a smoothappearance free of welts and ridges and the ends thereof are of likewise smooth appearance.

The amount of the oscillation and the frequency thereof will vary with the different grades of paper and other factors, but in general I have found a movement of oscillation of approximately ",2 of an inch every 90 seconds to be satisfactory for most work.

While the invention has been described in reference to a rewinding operation, it is not to be so limited in its application; as it is obviousthat theweb may be so treated when it is wound on the Fourdrinier machine, it being necessary merely to provide means for oscillating the windto be shifted co-axially while the web is unrolled, means to induce periodic oscillation of said shaft concurrently with its movement of rotation and thereby cause lateral aberrations of said web from its mean direction of travel.

2. A roll rewinding mechanism including an unwinding roll shaft adapted to be rotated and to be shifted co-axially while the web is unrolied, means to induce periodic oscillation of said shaft concurrently with its movement of rotation and thereby cause lateral'aberrations of said web from its mean direction of travel, and means for adjusting the roll shaft longitudinally and angularly.

3. The method of winding a web of paper and the like in a manner to prevent the building up of ridges due to superimposed minute irregularities in the thickness of the paper such as arise from its manufacture on a paper making machine, which irregularities run longitudinally of the web, consisting in oscillating said web in its own plane while the same is moving, passing the same between edge trimmers of a fixed distance apart less than the width of the web, and winding the trimmed web, the amount of the oscillation being less than the distance of the trimmer from the edge of the untrimmed web adjacent thereto. 7

4. A web-roll-supporting structure comprising a web-roll-shaft; means to induce periodic co axial oscillation of said shaft; and manually operable means to effect adjustments of said shaft lengthwise and transversely, independentlyv of said periodic oscillation thereof, and during said oscillatory movement.

5. The method of winding a continuously furnished web of paper and the like in a manner to prevent the building up of ridges due to superimposed minute irregularities in the thickness\ of the paper such as arise from its manufacture on the paper making machine, which irregularities run longitudinally of the web, consisting in continuously oscillating said web laterally in its own plane during the winding operation in an amount exceedingly minute in comparison with the width of the web, thereby distributing substantially uniformly such longitudinal irregularities over a lateral distance equal to the amplitude of the oscillation.

6. In combination, a winding roll shaft, and an unwinding roll shaft for rewinding a roll of paper web on the unwinding roll shaft, means for driving the winding roll shaft and means for continuously oscillating said web laterally in its own planeduring the rotation of the winding and unwinding rolls, such oscillation being in an amount minute in comparison with the width of the web.

7. A web roll supporting structure comprising,

a web roll shaft, means to induce periodic coaxial oscillation of said shaft and manually operable means to eifect adjustment of said shaft lengthwise thereof, independently of said periodic oscillation and during said oscillatory movement.

8. A web roll supporting structure comprising a web roll shaft, means to induce periodic co- 'axial oscillation of said shaft and manually operable means to effect adjustment of said shaft transversely thereof, independently of said periodic oscillation and during said oscillatory movement.
