Original application led December 16, 1918, Serial No. 266,862. Divided and this application 11nd July 10, 1920. Serial No. 395,276.

To all whom it may concer/n.:

Be itknown that I,.WILLIS S. CRANDELL, a citizen of the United States, residing at Elsmere, in the county of Albany and State of New York, have invented a certain new and useful Machine for and Process of Producing'Rolls of Paper for Towels, Toilet Paper, Etc., of which the following is a specification.

My invention relates to a machine for and process of producing rolls of paper for towels, toilet paper, etc. A

The object of my invention is to provide a process of and a machine for winding rolls of paper towels, toilet paper, etc., which shall have the advantages, among others, of forming or winding the rolls without breakage of the web of paper from which said rolls are formed, and of providing a machine which is simple and readily operated and adjusted.

The present application is a division of a prior application, Serial Number 266,862, filed by me on December 16, 1918.

My invention in the process is capable of being performed by mechanical means of many different forms and my invention in the machine is capable 0f embodiment in `many different forms. While, therefore, I shall illustrate my invention by the best embodiment known to me, such embodiment is to be regarded only as typical of many possible embodiments, and my invention is not to be confined Ithereto.

In the manufacture of rolls of paper towels and toilet paper, it is customary to wind the roll of paper coming from the paper-formingmachine into a large roll Y called a jumbo roll, from which rolls that i0 are usually both smaller in diameter and narrower in width are to be formed, to make rolls of towels or of toilet paper. My invention relates to a process and machine for making the latter type of rolls.

Fig. 1 is a-rear elevation, with certain parts broken away, of the illustrative machine;

Fig. 2 is a side elevation thereof, looking toward the rightk hand side.l as viewed in 50 Fig. 1;

Fig. 3 is an'elevation of the side opposite carriage Fig. 5 is a vertical section taken on the hne 5--5 of Fig. 1, looking in the direction ofthe arrows;

Fig. 6 is an enlarged fragmentar detail in section taken on the line 6-6 o Fig 1, looking in the direction of the arrows;

Fig. 7 is a detail vertical longitudinal section taken on the line 7-7 of Fig. 6, looking in the direction ofthe arrows;

Figs. 8 and 9 are detail plan views, partly in section, of the rewinding shaft with the adjacent co-operating parts.

My process and the principal operative parts of the machine which I have selected as one means of performing the process will first be explained in outline (by reference to Figs. l and 6),.after-which the explanation in detail will be more easily understood. In the said figures, the web 1 is shown as led from a jumbo roll 2 (having an axle 3), preferably over a pinch roll 4 to the surface of a drum 5, around the periphery of which the web travels, the web being wound upon a rewinding shaft 6 to form a rewound roll 7 of towels or toilet paper. In its passage around the drum 5, Y the web is preferably cut transversely" (but not completely severed), by serrating knives 8 carried by a sei-rating roll 9, which knives are received in grooves 10 1n the drum 5. A second pinch roll 1l is preferably provided on the opposite side of the drum 5 from' the pinch roll 4.-, said rolls serving to hold the web against the surface of the drum and the first pinch roll also serving to support the web in its assage from the jumbo roll to the winding rum. The paper wound upon the rewinding shaft 6 is severed longitudinally by annular knives or cutter discs 12 carried by a slitting roll 13. The slitting roll is driven at a Afaster surface speed than the winding drum and, therefore,

4tends to roll the paper tightly upon the re- 100 windin shaft, and thus tends to make a relative y small, compact roll of a given len h of paper web.

aking u now the detailed description of the mac ine and the process practiced In the said machine there are side frames 14 on which are mounted the bearings of the various rolls beforementioned. The axle of the jumbo roll is laid in open bearings 15 formed on carriages 16, each of which is supported by a pair of rollers 17 on away 18. Each way 1s pivoted, preferably at its rearward end, on a fulcrum 19 mounted on one of the side frames so that the forward end of the way can be raised to cause Ythe carriage to tend to roll toward the windin drum. Each way is preferably provided l with an arm or other projection (which in the present instance is in the form of a sector 20) which, by an adjustable connection with the side frame can be made to su port the way at any desired inclination. n the present instance I have shown the said sector as provided with a curved slot 21 through which passes a bolt 22 that is fastened in the side frame. A threaded rod 23 is secured on ribs or flanges 16a which project into grooves Y formed in the ways, and thus the carriages are prevented from rising olf the ways.

As a further means for causing the jumbo roll to tend to move toward the winding roll, a chain or other form of flexible connection 26 is attached to each carriage and is passed Y rearward (toward the winding drum)'and around a guide pulley 27, an thence forward and around another guide pulley 28 from which the chain hangs vertically, and

supports a weight. By using a proper inclination of the ways or a suitable weight 29, or both, the jumbo roll can be forced toward the drum so that it will always be in contact either with the pinch roll 4 or with the drum, if, as might be done, the pinch roll were omitted. As the diameter of the jumbo roll decreases, its axle is moved forward so that its periphery is always in contact with 'the pinch roll or the winding drum. This l arrangement always affords uninterrupted support for the web in its travel from the jumbo roll to the winding drum and thus eliminates a frequent cause of breakage of the web. The winding drum 5 is mounted in stationary bearings in the side frames,

' and in the illustrated embodiment of my invention it carries a driving pulley 30 by which the entire machine is driven. Pinch nausea rolls 4 and 11 are each so mounted as to be movable toward and from the winding drum to maintain a constant pressure against the winding drum notwithstanding any possible variations in the periphery of the said drum or in the thickness of the web oflpaper to be wound, and the said pinch rolls are preferably yieldingly pressed against the windin drum. In the resent instance the pinc rolls are journa led in the upper ends of arms 31 which are fulcrumed on pins 32 that are supported by the side frames, and each arm is yieldingly pressed toward the winding drum by a spring 33 mounted on a bolt 34 which passes through an opening in the said arm and through a flange or web on the side frame, a nut 34 on the said bolt resting against the said liange and serving to adjust the pressure of the spring against the arm. The serrating roll 9 is journalled in the side frames belowl the drum 5 from which it is driven by gears 35 and 36 mounted lon the axles of said rolls. The serrating roll is, in

the present instance, shown as provided with three serrated knives 37 having saw-tooth edges, which knives enter the grooves 10 on the winding'drum and partly but not wholly sever the web of paper transversely. The pinch rolls, by holding the web tightly against the surface of the drum, and the slitting roll 13, by travelling at a faster suri face speed than the winding drum, hold the web tight across the grooves so that it resists the tendency of the serrating knives to push it into the grooves and causes a ood cutting action to take place. The rewinding shaft 6 simply lies upon the surface, preferably the upper surface of the drum, and preferably by having spring journals in its ends extending between and held in place by two vertical ribs or splines, so that it can rise as the roll of paper wound upon it increases in diameter, but it is preferably not driven by power applied to it. The spring journals (shown in detail in Figs. 8 and 9) recede into the end of the shaft when placed in the machine and pass through slots in the opposite spline when removed. The slitting roll 13 consists of la shaft 13a upon which is threaded a series of rolls 13 having the annular knives or cutter discs 12 between them. I desire to drive the slitting roll sothat its surface speed shall be greater than that of the winding drum, and Consequently so that its action will be to tend to wind the roll being formed upon the rewinding shaft tightly to make a relatively hard and small roll, and I also desire to permit the 'slitting roll to recede from the rewinding roll as the diameter of the roll being formed increases. For this purpose I mount the slitting roll in bearings formed in a vertical, slidable gate or frame consisting in the present instance of bars 38 in the lower ends of which the said shaft 1s journalled), which bars are mounted in vertical guides formed .in uprights 39 onthe side frames, the said bars being connected by a brace 38 in order to drive the slitting roll. The shaft of the said roll is extended through a slot 39a formed in one of the uprights 39, and the extended end of the shaft is, in the present instance, shown as journalled in a bearing supported by a bracket 40, which extends from the gate or slide 38 around the upright into position to support the said bearing. The shaft 13 of the slitting roll is provided with a sprocket wheel 41, and in order to drive the said wheel and yet permit the latter to move up and down with the gate, I have provided the following arrangement: A sprocket chain 42 passes around a driving sprocket 43, that is frictionally secured upon the shaft 5a o f` the winding drum, and around a guidlng sprocket 44, journalled on a stud .secured to the upright 39. The frictional drive for the sprocket gear 43 is in the present instance shown as consisting of a hub 45 fixed on the said shaft and against which the sprocket gear 43 rests, a preferably fibre disc 46 rest- 1ng against the opposite face of the sprocket gear, and a split nut 47 threaded on the shaft 5 and adapted to be secured in adjusted position by a screw 5b bgg which the split can be drawn together. etween the driving sprocket gear '43 and the guide pulley 44 the sprocket chain 42 passes over a sheave 47a mounted on a plate 48, which latter also car' ries a `flange 49 that is adapted to bear against the side of the chain opposite the sprocket wheel 41 on the slitting roll shaft and to hold the chain so that the latter` sprocket gear will always be in contact with it and be driven by it, no matter in what position toward or away from the winding drum the slitting shaft may be. In order to keep, the said adjustment and allow for wear, the plate 48 is adjustably mounted on the frame by being set against a vertical flange or plate 39b on the upright 39 to which fiange the plate 48 is secured as by bolts 39c in one of said parts and passing through lslots in the other of said parts.

By this construction, the driving sprocket gear 43, rotating with the shaft of the drum, tends to drive the slitting roll at a surface speed greater than that of the outermost layer of paper on the roll being formed, and the friction drive before described permits the ear 43 to yield so that, while the paper on t e roll being formed is put under tension and is rolled tightly, it is not torn. A relatively hard, compact and desirable roll is thus formed without breaking the paper.

It is in order that the slitting roll may be raised to permit the rewinding shaft 6 with its rolls of paper thereon to be removed from the machine and the empty rewinding shaft replaced in the machine, that the slitting roll shaft has been mounted in the besure of the` slittino' fore-described gate or slide, and means have been provided for raising and lowering the latter. ,In the present instance the means consist of racks 50 formedon the bars 38, in which the slitting roll shaft is journalled, pinions 51 mounted on a shaft 52 that is journaled on the uprights 39, and means for turning the said shaft. The lattermeans shown consist of a sheave 53 having a sprocket chain 54 wound thereon in such a direction that the pull of the sprocket chain shall tend to raise the gate, while-'the weight of the gate shall tend to wind the sprocket chainup on thesheave. The sprocket chain 54 is shown as connected to a treadle 55 `which is secured to a shaft 56 having a fixed bearing, which shaft carries an arm 57 upon which a weight 58 is adjustable, so that by adjusting` the said weight the desired presroll upon the rolls of paper will result. "lhe bearings of the shaft 52 are made adjustable so that the slitting roll can be adjusted'to bear evenly on all the rollsbeing formed on the rewinding shaft. In the present instance the said bearings 59 are shown as adjustably secured to a vertical face of the' uprights 39 and resting upon vertical screws 60, which pass through' lugs 61 secured to the uprights.

It is to be observed that the roll 13 carrying the slitting knives 12 will itself normally be in peripheral cont-act with the roll of paper being formed upon the shaft 6, due to the fact that the knives l2 will cut through the web of paper, so that not only do the knives 12 function as slitting knives, but the roll 13 functions as a pressure roll, constantly in yielding contact by gravity with the surface of the paper roll 'being formed and pressing that roll as it is being formed downward upon the forming drum 5. Also the roll 13 in its capacity as a pressure roll, and by its rotation.at a greater peripheral speed than the roll of paper being formed and at a greater peripheral speed than the drum 5, tends to draw the advancing web of paper into a tight, compact roll.

Where it is not desired to slit vthe advancing web of paper into narrower strips, the slitting knives on the roll 13 will, of course, be dispensed with, and this, it is to be observed, does not modify in any degree the function of the roll 13 as a pressure and drawing roll.

The term slitting roll has been used in this specification as a convenient designation of the roll 13, but it is to be understood that I do not by this designation intend to confine the roll to its slitting function, the terms pressure roll and drawing roll being equally applicable to designate other functions of this roll. The group of elements comprising the rollers 4, 5, 6, 11 and 13 constitute a rewinding mechanism.

Stating in full the operation of the illustrated embodiment of my invention:V The shaft of the jumbo roll is laid in the bearings of the carriage 16 (and is` preferably secured therein by means not necessary to `describe), and the web of paper 1 is led over the pinch roll 4 and between the pinch roll and the drum 5, and then under the drum and between it and the serrating roll 9, and upward around the drum between the rear pinch roll 11 and the drum, and is then rolled around the rewinding shaft suiliciently to engage it therewith, all as shown articularly inv Fig. 6. The gate which, uring the latter operation, hasbeen held elevated by pressure of the foot on the treadle 55, is allowed to descend until the slitting roll rests upon the rewinding roll. Gravity tends to cause the carriage 16 to slide down the ways 18 toward the drum 5, and this tendency is increased by the pull `of the weights on the sprocket chains 26. Thus the jumbo roll is held against the pinch roll 4, and the latter serves to support the paper in its passage to the drum. The pinchrolls also hold the paper smoothlyv against the drum, preventing its wrinkling, the pressure of the springs 33 against the arms carrying the pinch rolls assisting. As the web passes around under the drum, it is serrated at proper intervals by the knives 37 carried by the serrating roll, which enter the grooves 10 in the drum, the paper being held tightly across the said grooves by the pinch rolls and by the pull of the slitting roll and the friction of the shaft of the jumbo roll, so that the serrating knives `cleanly penetrate the paper instead of merely tucking it into the said grooves. The gearing for driving the slitting roll tends to drive it at a higher surface speed than that of the drum, so that said roll pulls the paper forward and winds it tighter around the rewindin shaft, as well as pressing the paper roll being formed between itself and the drum, and thus a relatively hard, compact roll is formed on the rewinding shaft, the yielding or friction drive ofthe slitting roll, however, preventing the slitting roll from tearing the paper. The slitting knives slit the web longitudinally so that instead of a single roll of the width of the paper, a number of separate rolls are formed on the rewindingl shaft. The drive of the slitting roll shaft, consisting as it does of the sprocket wheel 41 engaging the vertical stretch of the sprocket chain 42, drives the slitting roll equally well, regardless of the fact that the increasing diamet'er of the roll being formed causes the slitting roll to rise. The driving gear of the slitting roll also causes a uniform pulling action of the surface of the slitting roll on the surface of the roll being formed, this ull not changing as the roll being formed increases in diameter. This is much simpler than any arrangement for driving the rewinding shaft by gearing, since in the latter case it would be necessary to change the speed transmitted by the gearing as the diameter of the roll being driven increased. When the rolls being formed, however, reach the desired diameter, the web is severed, the slitting roll is raised by pressure on the treadle 55, and the rewinding shaft is lifted l out of itsvertical guides. The rolls which have been formed are then stripped oif the rewinding shaft, and the web is again started around the rewinding shaft and the formation of new rolls is begun..

l Among the advantages of my invention may be stated the following:

Throughout all of the steps of my process of forming a new roll, the web of paper is v supported by continuous supporting surfaces in physical contact with the web, these supporting surfaces also having a peripheral movement equivalent to that of the advancing web of paper, and thereby, among other results, the liability of breakage is reduced` While the slitting roll. can be raised and lowered to permit the rewinding shaft to be removed from and placed in the machine and to allow for increase of diameter of the yrolls being formed, its driving mechanism is comparatively very simple.

The-driving of the slitting roll at a faster surface speed than that of the drum results in a relatively ha'rd and small roll being formed and by mechanism which is comparatively very simple, and yet the .yielding drive for the slitting roll prevents breakage of the web being operated upon.

The stock or parent roll being. always in contact with and driven by thenearer pinch roll or the drum, is driven at the same surface speed as the pinch roll or the drum and also at the same speed as the roll being formed, which not only prevents, to a considerable extent, breakage of the web; but also effects a considerable saving in the time required to stop and start the machine. If it were not for this contact drive, both the machine and the stock roll would have to be started and stopped slowly, as otherwise the web would be broken, due to the inertia of the stock or parent roll, and in stop ing, the momentum of the latter roll woul carnation of means forV 2.
