To ail whom it may concern Be it known that I, HARRY LIEBECK, a

citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented an'Improvement in Machines for Making Toilet-Paper Rollsyofwhich the following is a specification.

My invention has reference to machines for making toilet paper rolls, and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof. l

The object of my invention is to provide a construction of paper winding machine for making toilet paper packages in roll form which will permit of a practically continuous operation by bringing into winding position one mandrel after another in rapid succession, with the result that the output of a single machine is greatly increased over what has heretofore been possible with this class of machine. I i

My invention consists in the combination of means for perforating, (with or without slitting a web of paper) with rewindlng means comprising an adjustable frame provided with two or, more detachable mandrels arranged to be successively brought into operative winding position, and means for rotating the"mandrels when in operative winding position; further, in a machine of the character "stated, ,when provided with means for insuring the rotation of the mandrels only when in winding position, whereby the operator may withdraw a filled mandrel when out of winding position and after removing the paper rollsreadjust the man drel upon the carriage and into operative relation with the means for rotating it; fur,-- ther, in providing the above described machine with perforating cutters which so cooperate with the slitting cutters that the adjacent webs, formed by the slitting cutters upon the single wide web, shall be perfo rated or cut, whereby the incisions shall be out of transverse alinement and'the weakest portions of the'perforat ed webs will not all be subjected to the windingtension at one time.

winding machine embodying my invention;

Fig: 2 is a plan view of the same with a portion broken away Fig. 3 is a sectional elevation of the same on line 00-32 ofFig. 2; and Eggs. Land 5 are sectional views of the means for rotating the mandrels,

2 is the main frameof the machine.

3 is the supporting shaft or mandrel upon which the large roll of paperis'placed; and said shaft 3 is provided with a brake wheel 4 against which a friction shoe 5 mav be pressed under control ofthe screw shaft 6 extending to the front of the machine,

whereby a frictional resistance maybe put upon the large paper'roll to maintain the paper web 7 under tension during the slitting, perforating and rewinding operations. Any other suitable means may be employed for providing this tension to the paper web.

The web of paper 7 passes under a-guide and feed roller 8, then upward and over a drum v9 and thence tothe winding mandrel 35. While the paper is-p'assing about thedrum 9 it is first perforated transversely at intervals by the perforating blades 16 of a roller 10 and then'slit longitudinally by the slitting cutters 12 on the shaft 17; The" drum 9 is made with a series of circumferen-r tial cutting edges 15 for cooperating with the slitting cutters r12,'and is also provided with a series *of transverse grooves 14 for cooperating with the perforating cutting blades lG'for partly severing the web 7.

By the combined action of the cutters '12 and blades/16, a series of narrow webs of paper are formed, eachofwhich is perforated transversely at intervals, so as to form short connected sheets which are simultaneously wound'upon the mandrel 35. r

To prevent the pull of the mandrel rupturingthe perforated webs, I prefer to arrange the blades 16 and the grooves 14: in suchmanner-that the adjacent transverse perforations, before slitting takes place, shall be cut out of alinement or staggered, as, will be'understood by reference to Fig, 2. By this means there is considerable body of paper between the adjacent transverse perforations, and the f ictional Contact or, such paper with the drum feeds it forward and supports it'during the slitting operation, The feeding action of the roller 8 (which may be. covered with rubber) removes all excessive strain from the webs during the geared together by gearing 18 to insure their speeds being such as to properly cooperate in the manner above described. The drum 9 is driven by a band wheel 19- having a disengaging clutch 52 of any suitable construct-ion, which may be put into or out of action by a shifter shaft 20 having a pin 24 cooperating with a fixed cam surface 25, said shaft 20 being rocked'by crank 21, link '22 and hand lever mechanism 23. Any

other suitable means may be employed for putting the machine into and out of operation. A hand Wheel 19 may be employed on the shaft of the drum 9 for adjusting the machine when the clutch 52 is out of gear. Thegeneral construction of the machine above described may be modified as to. its

elements and arranged to produce one or more webs to be rolled at one time, but where there are a plurality of narrow webs to be made and wound, I consider it most important to arrange the perforating blades 16 out of alinement.

I will now refer more particularly to the means for and manner of winding the perforated strips of paper upon a mandrel to form the rolls of paper in commercial form. 26. is-a pivoted frame which is pivoted at 27 to the main fra e 2, and has, at its upper orfree end, a transverse shaft 29 journaled therein and provided'with disks 30 near each end. Between the disks 30 and removably supported, are the mandrels upon which the webs of paper are wound. One of the disks 30 is'provided with a series of shafts 36 having pinions 49 on one -end and chucks 37 on the otherend with which the end of the mandrel 35 engages and by which it is rotated. The mandrel 35 is provided with a pin 38, as shown in Fig. 4, and this pin engages a shoulder in the chuck 37 so that the rotation of the latter causes the mandrel to be rotated with it. The other end of the mandrel 35 is detachably supported upon a spring actuated center pin 40, which'is carried in the other disk 30 and spring pressed toward the mandrel-by means of a coil spring 41, as shown in Fig. 5. I have shown four of the chucks 37 on one of the disks 30 and four of the 1 spring actuated center pins 40 on the other disk 30, so that there .is capacity for employing a plurality of mandrels between the two disks 30 at one time. One Of'tl'le disks is provided with a series of notches 31 corresponding in number to the spring actu-- ated center pins 40 and engaging these notches is a locking pin 33 carried by a .lever 32 which is pi'votedto. the. frame 26.,

and held in locking position by means of a spring 34. By reference to F ig.. 3, itwill be se en that, by disengagingthe pin 33 from the notch 31 the shaft 29, together with its disk 30 and mandrels, may be rotated so as to bring into operative position another mandrel to take the place of the one upon which the paper webs have been fully wound.

The operation of unlocking the shaft 29 and its disks and rotating it to bring anew mandrel into operative position 1r ay be ac complished without interrupting the operation of the machine as a whole except for a moment; and. because of the facility 'of removing a filled mandrel'and bringing a fresh mandrel into operative position, the

capacity of themachine is greatly increased. lVhen the machine is innormal operation, the pivoted frame 26 leans toward the drum 9 as in Fig. 1; and when the mandrel is filled, the frame assumes a vertical position as shown in Fig.3, at which time it becomes locked by means of the notch and locking lever 28. By raising this lever 28, the frame, together with its shaft 29, may be thrown, outward and away from the drum 9 for permitting access thereto The rotation of the mandrel 35 181 accomplished in the following manner chain wheel upon the drum 9 drives a chain pulley 44 upon the shaft 27 by means of a chain (1r belt 43. The pulley operates a second pulley 45 through a friction clutch 50, the

29 and its disks 30 are rotated into sue-- cessive positions of adjustment and locked in said positions successively by the locking means 32 and 33, the pinions 49 of the several chucks are successively brought into engagement with the rotating gear 48 which is journaled on the pivoted frame 26 carrying the shaft 29. In-this way the chucks are successively brought into operative po-' sition and rotated, for imparting rotation to their respective winding mandrels. From Fig. 1, it will be seen that the chuck nearest to the drum9 will be'rotated by means of this power transmitting mechanism and consequently the mandrel connected with the said chuck will be caused to rotate. During the rotation of the mandrel, its speed will'be g'overnedbythe amount of paper to be wound which may pass to it from the drum 9, and a variation of thisspeed is permitted because of the presence of the frictionclutch 50 between the two .chain orbelt wheels44 and 45.

Whenthe machineis' inoperation, 'the' tinually rest against the surface of the drum 9, as ndicated 1n Fig. 1, the saidaction being permitted by liftingi the lever 28 and moving the frame 26 and it's shaft29' toward the said druni. As'fthewebs of paper are rolled upon the mandrel and increase in diameter, they push the mandrel gradually away fronrthe drum; and when the proper size'of roll is co1npleted,-the frame 26 will have been' lnoved from the position indicated in Fig, 1 to almostthe' position indi-'- cated in Fig. 3. .The operator then pulls the frame. 26 into engagement with the lever 28 which locks to the transverse rod 53 on the said frame. and'holdsthe same'stationany." He 'may then stop the machine by throwing the stop lever mechanism 23. Pre' vioushto the stopping of the machine he has inserted an additional mandrel between the next chuck "and center pin to come into operative position. W'hen the parts have assumed the position indicated in Fig. 33nd the machineis stopped, the "operator disengages the {pin -33'-fr'on1 the notch 31and rotates the shaft 29 with its disks and mandrels until the pin engages the next notch 31. The 'filled mandrel is then removed by disengaging ;-it from the chuck and center pin and the paper webs broken and the' ends thus made quickly attached tothe new mandrel and, after disengaging the lever 28:, the frame 26 with its shaft 29 is thrown into the position indicated in Fig 1" and the lever device 23 agairi thrown to put the ma ,chine into operation. These operations are 'Trepeatedfwit-h the'introduction of every new mandrel. Q 1 I It will be noted thatwhen the disks 30' are rotated, the pinions'49 and ,the

tatd when in'winding position 'andwh'en the machine.is in ope'ratirm, so that it is evident that-a new mandrel may be placed imposition and a filled .mandrel 1nay be removed while the machine is in operation, because the chucks carrying the last mentioned mandrels are not being rotated.

-Ihave shown my inventionfladapted to :the slitting of wide webt7 into a series of narrower webs, all of which are simultaneously wound upon the. same mandrel 35, but Iydo not restrict myself to such slitting, as the rewindingfeatures of my invention may be applied to cases where only asingle web is operated upon;
