This invention relates to a rewinding mechanismy and is designed more particularly for winding'a plurality of webs ofpaper, or the like, in superimposed relation, 1nto a single sroll, which is commonlytermed a. unit roll.

One objectof the invention is to provide ,such a mechanism which will be simple in` its construction and operation and which.

will accurately wind thexsuperimposed webs A further object of the invention isto provide such a mechanism with means `for properly positioning the webswith relation one to the other and for maintaining the 15 same. inl proper position vin relation one to the other an in relation to the unit roll as they are wound onto the unit roll, thus maintaining the several webs in proper alinement in thev unit roll. f 1

vide such a mechanism which will properly positionfwebs of diii'erent widths with relaltion one to the other and to the unit roll..A

Another object of the invention is to pro- ,vide such a mechanism with im roved means .for rotating the unit rol'l and or maintaining the roll in proper contact with thel driving means. y

Other objects of the invention will appear as the mechanism'is described in detail.

In the accompanying drawings Fig. 1 is a side elevation of a winding mechanism embodying m invention; Fi`2 is a section taken on t e line 2--2 of ig.x1, showing rolls in plan; Fig. 3 is a section l e line 3-3 of Fi 5, looking in the direction ofthe arrows; i 4 is'a section taken onv the line 4-4 of idg. 5, look#4 ing in the direction of the arrows; Fi 5 is taken on t a vertical sectional view taken throug the forward4 end` of the mechanism, on the line 5-5 of Fi 2; and Fig. 6- is a sectionaldetail view 0% theI guide rod for a narrow web.

In these drawin vI have illustrated One .45 embodiment-of my invention and have shown the same as comprising a supporting structure or main frame '10 which is provided with means for individually supporting thereon` a plurality of webs of paper or other similar A further object of theA invention is to provThese webs may be supplied in `different lforms' but usually 'come either inrolls or in stacks of folds and the .character of the supporting means for the webs will Lnecessarily depend in part upon the form in which thewebs lare su plied. The lresent mechanism is designe for use wit mined b'y the number. of webs which are toA bewound into the unit roll. The present webs 1n roll form and is therefore provided with a` -mechanism is capable of handling any numi ber of webs up to twelve and thereforehas twelve pairs of bearings 11. Thesebearings are preferably open bearings, or half bearings, so that the shafts 12 may bereadily placed in or removed from the same.,

V The webs 14 of all the rolls, except Ithe two at the left hand or rear end of the 'supporting structure, areirst carried vabout guidev rods 15, thence rearwardly and about other. ,guide rods 16, thence forwardly between aA pair of spaced guide rods 17 tothe forward end of the machine. The webs from the two rolls at the rear end of the supporting frame l are, in the present instance, carried directly to the guide rods 16 and thence forwardly with the other webs. In this manner the several webs are arranged in superimposed relation and in the roper order.

The forward en s of the superimposedwebs are wrapped about or otherwise .secured f to a core 18nonwhich the unit roll isto be wound and means are provided for rotating this roll in a direction to draw the webs from the several individual'rolls and tp wind the same Onto the unit roll. Preferably the unit roll is rotated b means of friction rollers to v contacting with t e cylidrical surface thereof, y

thus causing the unit roll to be lrotated at the l i' same speed regardless of. the gradually irlv creasing diameter thereof. As hereA shown, two frictional driving rollers-19'and 20 arel arran ed 'with'their axes in substantially the same orizontal-plane and are spaced apart such a distance as to form a. proper support for the unit roll. The frictional driving rolls 19- and'20 arerigidly secured respec- 5"erably they are provide gears 24 and 25 which mdh with a gear 26- tivel to shafts 21 and 22 which are journale in a supplemental frame 23 mounted on the main frame 10.4 The driving rolls may be actuated iii-'any suitable manner but prefat one end with mounted on a shaft 27 also journaled in the supplemental frame 23 and having at one end means for rotating the same, such as a belt pulley 28.

It is important that the several webs should begin proper alinement one with the other when they are wound on the unit roll, particularly when the webs are provided with printed forms for use in a manifoldingmachine. The present mechanism has means for first properly positioning the webs with relation one with the other and for maintaining them in that position as they are Wound onto the unit roll and, as here shown, ythe several webs 14 are threaded through individual guideways 29 formed in a guide 30 which is rigidly mountedon the supplemental frame 23. This'y guide comprises a series of superimposed bars 31 each ,having in its upper surface a longitudinally extending recess of a width substantially equal to the width? of the web and which constitute the guides 29. The bans 31y are mounted in fixed positions 'with relation one ,to the other and consequently the webs are brought into vertical aline-ment as they passthrough the guide.

'f guide bar 31 is made of a width substantially It is sometimes desired to have one or more of the webs of a less width than the others and in such cases' the recessin the corresponding equal` to the width of the narrow`web, as shown at32. in Fig. 4, and this recess is so arranged with relation to the recesses in the other guide bars as tol properly position the narrow web with relation tothe other webs. The su erimposedl webs, as they pass from `the guide 30, are carried beneath the driving rollers 19 and 20.,-thence upwardly about the 145 foremost roller 20 and about the core 18. The r. webs are given an initial wrap about the core sufficient to retain the same thereon and the roll which is'thusistarted is placed upon the A driving rollers which are so arranged as to 50' retain the unit roll thereon and to rotate the kAsan'lein a dii'ection to draw the .webs from the individual rolls andwind the same upon the unit roll, and inorder to maintain the webs 'in their pro er relative positions with relation oneto the other .and to the unit roll the driving rollers 19and 20 have mounted there- Aso " onynear the ends thereof, collars 33, th'collars on each roller being spaced "apart a diswider webs and being of a thickness or depth considerably 'greater than the combined thicknesses of the-several webs.

rigidly secured to therv respective rollers, thls The collars are bengaccomplished in the present instance by means of setscrews34 which will permit tance substantially equal-to the width of the' the collars to be adjusted to accommodate the same to webs of diferent widths. The unit roll when in position on the driving rollers will rest between the shoulders formed by the collars 33 and will be held against lateral displacement thereby. In this manner the webs are maintained in proper alinement both with relation one to the other and with relation to the unit roll and will thus be wound onto the unit roll in proper positions with relation one to the other. Where a narrow web is employed as above mentioned it may be found desirable to utilize an additional guideto maintain this narrow web in its proper position a-s it passes lto the unit roll. In the present machine I have shown a small guide rod 35 arranged between the -narrow web and an adjacent web, at a-point below and between two driving rollers, and this guide rod has in its lower surface a recess 36 of alength corresponding to the width of the narrow web, thus making certain that the narrow web will be in proper position sok unit roll a round bar of metal 37 which is of` such a character that it can 'be readily revmoved when the roll has been completed. .Mounted above the unit ioll and arranged to restupon the uppermost portion thereof is a roller 38 which serves to retain the unit roll in proper position with relation to the driving rollers and also to press the same into contact with the driving rollers. This roller 38 is vertically adjustable and is so mounted that it will automatically accommodate itself to the increased diameter of the unit roll as the lrewinding progresses. Ashere shown, the roller is supported at the forward ends of the two arms 39 which are rigidly secured at their rear ends to rack bars 40 slidably mounted in guides 41 and 42 carried respectively by i the supplemental frame 23 and the main frame 10. Cables 43 extend` about pulleys 44 mounted near thetop of the main frame 10 near the respective sides thereof and each of these cables is connected at one end with a corresponding arm 39 andV at its other end `\'with a'- weight 44a.' These weights serve to partially counterbalance the yweight of the roller. 38 `and its associated parts but permit this roller to rest upon the unit roll and to exert some pressure thereon. The rack bars 40 mesh with pinions 45 carried by a shaft 46 mounted in the supplemental frame and provided at one .end with an actuating device, such as Ja hand wheel 47, vby means of which the roller 38 may be elevated to permit the removal of the completed roll and then lowered into contact with thenew unit roll.

Rigidly secured to the shaft 27 is a brake drum 48. A friction bandor strap 49 extends about this drum and is rigidly secured at one end to a fixed part of the suppleme-ntal frame 23, as shown at 50, and has its other end extending downwardly and connected with a foot leverr 51 by means ofv which it may be drawn into frictional contact with the drum, thus providing means for quickly checking the movement of the rewinding mechanism whenthe connection 'between the same and the source of power has been interrupted, as when the current to an electric motor has been turned off.

While I have shown and described one em'- bodi-ment of-my invention, I wish it to be understood that I do not desire to be limited to the details thereof as various modifications may occur to a person skilled in the art.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent, is: v

1. In a mechanism for rewinding a plurality of flexible webs in superimposed relation on a unit roll and including a roller having supporting enga ement with the unit roll arranged between said driving rollers and extending between adjacent Webs of different widths and having a recess to receive the web of less width and maintain the same in Vproper position with relation to the other Webs.
