Application med April 2, 1917. seria No. 159,266.'

T 0 all 'whom t may concern.'

Be it known that I, JOHN F. ANCONA, a citizen of the United States, residing at Rochester, in the county of. Monroe and State of New York, have invented or disto me April 17, 1917, I have shown' and described a machine for printing narrow, elongated strips or columns of reading matter upon a continuous web by means ofrotary printing cylinders, said strips being of greater length than the length or clrcurnference of the printing cylinders, and being produced 'in continuous form, that is to say, being free from joints such as would be occasioned by printing the strips in sections and joining them together. To, this end in said machine the printing surfaces are arranged in helical form on the printing cylinders, so that as the web of paper is passed through the machine the columns of reading matter are printedl diagonally thereon, that is to say, at a slight inclination to the length of the web. l

My prior patent aforesaid also discloses, but does not claim, means for cutting the web so as to separate the several columns of reading matter impressed thereon by the I stead of cutting the web immediately after vide means the printing operation to form the several tapes, it is found preferable (in order to prevent offsetting when a strip printed on both sides is wound up before the ink has had time to dry) to wind the complete web upon a suitable reel or roller with a tympan sheet or cloth, said tympan sheet. being interposed between the several convolutions of the web. The present invention has therefore for an object to provide a machine capable of Kunwinding such a combined roll of printed web and tympan material, of rewinding the tympan sheet, and of slitting or cutting the web in the desired manner to form the strips or tapes.

Another o ject of the invention is to pro- Or trimming the ends of the tapes formed by the slitting mechanism, so as to remove surplus material therefrom and give said ends such form or shape as may be necessary to adapt them to the purposes. for which they are to be used or to such further operations as are to be performed thereon. A

A further object of the invention is to provide improved winding mechanism for separately winding the several strips or tapes,

to compensate for the inclined; position of said strips with respect to the web.

The foregoing and other more particular objects of thev invention, together with means whereby the same may be carried into effect, will best be understood from the following description of one form or embodiment thereof illustrated in the accompanying drawings. It will be understood, however, that the particular construction and adaptation described and shown have been chosen for illustrative purposesmerely, and that the invention, as defined by the claims hereunto appended, may be otherwise practised without departing from the spirit and scope thereof.

Fig.l `14 is a detail view `of one of the winding cores, showing the attachment of a strip thereto. C In accordance with the process for which the machine herein shown is adapted, the

the line 12-12,

paper or other web 26 (see particularlyV Fig. 3) is slit or cut diagonally, or at an inclination to its len th, to form a plurality of strips 43,'the cuts by which said strips are severed commencing at one edge of said web and terminating at the opposite edge thereof.

20 (Figs. l, 2, and 5) denotes the machine frame, which is of suitable form and size to afford the necessary supports for. parts hereinafter re-` the various `machine ferred to.

21 denotes the main or power shaft of the machine which is journaled in suitable bearings in the frame 20 and is provided with a belt pulley 22 or other equivalent means whereby it may be rotated from any suitable source of power. v

55 and 56 (Figs. 1, 2, 5, 6, and 7) denote upper and lower slitting cylinders carried by shafts 57 and 58 journaled in bearings 59 and 60 suitably mounted in the frame 20. Thelower cylinder 56 is .keyed to the lshaft 58 upon which is secured a gear v62 meshing with a gear 64 on the power shaft 21. Secured to the cylinder :56, as by bolts.

68, is a gear 66 which meshes with a gear 67 keyed to the shaft 57. By these connections the shafts 57 and 58 are rotated in unison from thepower shaft 21.

.On the surfaces of the cylinders 55 and 56 Lemme are helical slitting^` knives 69 and 69) respectively. rlhe pitch of the helices followed by these knives .upon 'the cylinders corresponds to the desired inclination of the strips 43 with respect to the web 26, the spacin of the convolutions of said helices accordingly corresponding to the width of nsaid strips. The slitting knives 69 andv 69x tween the coperating slitting knives, thereby providing for a positive and efficient shearing actlon, the following construction is provided.

The upper slitting cylinder is not keyed to the shaft 57 but is loosely mounted thereon and is providedwith an inwardly turned flange 71 formed with a series of openings to receive pins 72 projecting inwardly froml a ring 73 rotatably mounted within a cylindrical flange 74 on the gear 67 and held in place by means of a rib or retaining ring 75 suitably secured to the inner face of said -lange 74. The ring 73 isformed with inu wardly projecting gs 76 between which and the lugs-77 on certain of the spokes of the gear 67 are interposed springs 78 whose tension is adjustable by means of screws 79 passing through the lugs 77. The rotation of the gear 67 is yieldingly transmitted through the springs 78, ring 73, and pins 72 to the cylinder 55. The arrangement of the parts is such that the tension of the springs 78 tends at all times to produce rotation of the cylinder 55 with respect tolthe cylinder 56 in a suitable direction to hold the coperating edges of the helical knives 69 and 69X in close engagement with one anrelative positions of the helices 0n the two cylinders, thereby causing the knives to en- 'gage one another at new points, so that should grooves or dents develop in the knives they could be so adjusted as to bring said grooves or dents at different relative points on the two knives.

The stock oll 23 (Figs. 1 and 2), upon which the web 26. and tympan sheet 24 are rolled together, is mounted in suitable bearings 25 at one end of the frame 20. The bearings 25 are preferably formed with open tops to permit a stock roll to be` inserted or removed as may be required, said stock roll being retained in said bearings during the operation of the machine by latches 27.

The tympan sheet 24, after leaving the stock roll, preferably passes over an idler roll 28, journaled in suitable brackets on the l the tympan sheet 24 as it is drawn from the stock roll 23. The belt 34 and pulleys 33- and 35 are merely illustrative of suitable driving means for the roll 29, it being obvious that said roll might be driven by the proper mechanical connections from` any convenient moving part of the machine.

The web 26 is drawn from the stock roll 23 and fed to and past theslitting cylinders by means of feed rolls 36, of which two pairs are shown, one at either side of the slitting cylinders. Said feed rolls are journaled in suitable bearings in the machine frame 20, the rolls of each pair be ing connected by gears 37 for rotation in A unison. For driving the rolls 36, the lowermo-st gear 37 of each pair meshes with a gear 38 which in turn meshes with the driving gear 62 of the lower slitting cylinder.

As will be seen from Figs. 3 and 4, when the web 26 is cut to form strips 43, there are formed, at the edge of said web, and at the ends of said strips, long taperin ends 39 which, for most purposes for whic said strips are employed, are useless. Moreover, for some i urposes it is desirable to give the ends olfJ said strips 43 a special shape, as, for example, that indicated at 40 in Fig. 4. For the purpose of trimming off the portions 39 and forming the ends 40, the following trimming mechanism is provided, said trimming mechanism being located beyond the slitting cylinders, and, as herein shown, beyond the last pair of feed rolls 36.

Secured tothe frame 20 at suitable points adjacent the opposite sides thereof are brackets 41 (see Fig. 2) having cylindrical portions 42 (see Figs. 1 and 8) constituting guides for plun ers 44 having at their lower ends heads 45 see Figs. 8 and 9) carrying trimming knives or punches 46. '.[he cutting edges of 'said trimming knives or punches are formed by pieces of tool steel properly ground and secured to the heads 45 by means of screws 47 having countersunk heads. The trimming knives .or punches 46 coperate with trimming dies 48 (see Fig. 10) also composed of steel strips similar to those constituting the trimming knives and secured by screws to die blocks 49 carried by the machine frame 20. The form of the coperating edges of the punches or -knives 46 and dies 48 corre-A sponds to the desired form to be given to the ends of the strips 43, and as herein shown said knives and dies are of a shape to *produce 'abruptly tapering ends, such as are shown at 40 in Fig. 4.

' As above explained, the ends of the strips 43 to be trimmed are at the edges of the web 26, and the location of the trimming devices at opposite sides of the machine brings them into the proper position to effect the desired trimming. Also, as above explained,

each of the strips 43 has its opposite ends adjacent opposite sides of the web 26; what may be considered lthe forward end of the strip being at one edge of said web, and what may be considered the rear end being at the opposite edge. Accordingly it willl be understood that the two trimming devices have their trimming punches and dies oppositely disposed, that shown at the bottom in Fig. 2 being so arranged as to form the end 40 shown at the right in Fig. 4, while that shown at the top in Fig. 2 is adapted to form the end 40 shown at the left in Fig. 4. v f

4 The downward movement ofthe plungers 44 to cause the knives to coperate with the dies 48 in eecting the trimming operation is caused and controlled by the following mechanism.

50 denotes a cam shaft suitably journaled in the machine frame and carrying at its end a gear 51 (see Fig. 1) connected by a gear 52 with the gear 62 on the shaft 58 of the lower slitting cylinder, whereby said cam shaft is rotated. Mounted on the shaft 50 adjacent the sides of the frame are cams 53 having substantially circular peripheries provided at suitable points with notches 54. Coperating with the cams 53 are cam rollers 61 carriedfat the lower ends of rods 63 ivoted at their-upper ends to levers 65. he rods 63 are guided for-vertical movement in brackets or ears 80 and 81 formed ony and projecting from the die blocks 49 and `that the pivotal connections between the levers 65, on the one hand, and the plungers 44 and operating rods 63, on the other, are

such as to provide for suicient play or looseness to permit the desired movements of the parts. 83 denotes springs within the plunger guides 42 and surrounding the plungers 44, said springs bearing at their lower ends upon flanges or collars 84 on the pluners and at their upper ends upon caps 85 s cured to the tops of said guides. The cams 53 acting through the rods 63 and levers 65, normally hold the plungers 44 and trimming knives 46 in their elevated or inoperative positions, against the tension. of the springs 83, as shown in Fig. 8. Periodically, however, as the ends 39 of the strips 43 are brought into proper position beneath the trimming knives, the rollers 61 enter the notches 54, permitting the springs 83 to impart to the plungers 44 a quick downward movement to cause the knives 46 to trim the strips, said plungers being quickly returned to normal position by the cams 53.

1n order to locate the trimming devices in their proper positions within the edges of the web 26, while permitting the cam rods 63 to clear said edges, the levers 65 are arranged at an angle to the longitudinal axis oFf the machine, as shown most clearly in 1g. 2. 4

After passing the trimming mechanism last described, the strips 43 are carried to the winding or reeling mechanism which, as herein shown, is as follows, reference being had to Figs. 1 and 2. 86 denotes a bevel gear mounted on th shaft of the lower feed roll 36 of the las pair of feed rolls and meshing with a bevel gear 87 on a shaft 88 journaled in a'suitable bracket projecting from the machine frame. The shaft 88 -is connected by a flexible coupling 89 with a shaft 90 arranged longitudif nally of the frame and journaled in suitable bearings thereon. Mounted on the shaft 90 are two series of bevel gears 91 and 92, respectively. The. gears 91 mesh with bevel gears 93 mounted on the shafts of horizontally disposed friction rolls 94 arranged transversely of the machine frame and journaled in suitable bearings thereon. The gears 92 mesh with bevel gears 96 on shafts of feed screws 95 arranged parallel tothe friction rolls 94 and also journaled in suitable v-bearin on the machine frame. Cooperating wlth the friction rolls 94 and feed screws 95 are winding boxes, designated as-a whole by the numeral 97, said winding boxes resting by gravity on the friction rolls 94.y

and having arms 98 provided at their ends with open threaded portions or half nuts 99 which rest by gravity on the feed screws 95. (See Fig. 13.)

As shown 1n Figs. 11 and 12 each-of the,

winding boxesy 97 comprises end members i* 100'connected by a plate 101 betweenwhich and an open top receptacle 102 is clamped the end of the arm 98. The end members 100 areprovided with U-shaped slots 103 closed at the outer 'sides of the winding boxes by cover plates 104. 105 denotes weight or pressure rolls, having reduced ends' which enter theslots or grooves* 103,

whereby said rolls are retained within the winding box, but are permitted free movement between the position shown in Afull lines in Fig. 12 and the position shown in dotted lines therein. 106 denotes the winding core which (as shown in Fig. 14) preferably comprises a cylinder of wood or other suitable material substantially equal in length to the clearance between the end members 100 of the winding box, and which is pro vided with a diametric slot to receive the taperedends 40 ofthev strips 43, whereby `said strips may be initially secured to the pressure rolls are arranged in pairs, one pairv for each winding box, and the rolls of each pair occupy positions at opposite sides of and slightly above the corresponding winding core, thereby retaining said winding core in its box during the winding operation. -As

the roll of fabric on a winding core increases in size the corresponding pressure rolls 105 move upwardly and outwardly, as indicated in dotted lines in Fig. l2, while remaining in contact with the fabric roll, thereby not only preserving the necessary driving engagement between the latter roll andthe friction roll 94, but causing the fabric to be wound with the proper degree of tightness.

The Winding boxes rest wholly by gravity upon the frictionrolls 94 and feed screws 95 and may be readily -lifted therefrom or placed thereon in any desired position. When a winding box is thus placed in position on-a friction roll and feed screw, said friction roll serves to rotate the winding cere in said box to wind up a strip attached therel to, and simultaneously the feed screw serves to move the winding box gradually across the machine as the winding progresses.

The receptacle 102 may conveniently be emplo ed to hold empty cores, or, if found desirable, a weight or weights may be placed therein to assist in holding the winding boxes firmly seated upon the friction rolls 'having been placed in' position in the bear ings 25, the end of the t mpan sheet 24 is drawn' oil', passed over t e idler roller 28, and secured in any suitable manner to the reel 29. The corresponding end of the web vices at the opposite side of the machine, said trimming devices are operated, as heretofore explained, to trim off the waste portions 39 and shape the ends 40. As the end 40 of each strip is thus shaped, the operator in-` serts the same into the slot in a winding core 106, places said winding core in a winding box 97, and deposits said winding box upon a convenient Jfriction roll 94 and feed screw 95 at the proper side of the machine. Thereupon said core 106 is rotated to wind the strip thereon, and as the winding progresses the feed screw 95 causes the winding boxes to traverse the machine laterally, as required, 4in order to compensatey for the inclined position of the strips in the machine. It will, of course, be understood that, until the stock roll is exhausted, the machine operates continuously, so that, as the strips 43 (as cut from the web 26) overlap one another transversely of the web, the winding ofseveral strips will be in progress at the same time, although in different stages of completion. As the winding of each strip upon its core is finished the transverse travel of the corresponding winding box will also be completed. The operator thereupon removes such winding box by lifting the same from its friction roll and feed screw, disposes of the completed roll of strip in any suitable manner, and returns the winding box to the other side of the machine for operation upon an-l other strip whose winding is aboutA to commence.
