2 Claims. (01. 164--99) 1 The invention relates to web perforating mechanism that is mechanism for punching holes at spaced intervals along a web of paper or other sheet material.

Heretofore, the perforating of a continuous web of paper or other sheet material has been accomplished by a rotary punch and a rotary cavity type die with the result that each punch has to aline exactly with its associated die cavity; and a very slight misalinement of parts results in punch breakage. Furthermore, wear occurs between the punches and dies so that replacement of parts is necessary accompanied by further time spent in getting as near perfect alinement as possible. The object of the present invention is to do away completely with accurately alined or timed cooperative dies by forming a rotary anvil, for use with a rotary punch, instead of a cavity type die, said anvil having an .oiiter surface of a deformable or ironable material whereby if said surface becomes rough, it may be readily restored to its original smoothness bylpressure contact of an ironing roll associated with it and readily adjustable relative to it by operative connection with a single control shaft.

The invention further consists in the sayeral features hereinafter set forth and more particularly defined by claims at the conclusion hereof. In the drawings: Fig. 1 is a front elevation view of perforating mechanism embodying the invention;

Fig. 2 is a plan view of the ironing roll control; Fig. 3 is an elevation view of said control; Fig. 4 is a detailed vertical sectional view taken on the line 4 4 of Fig. 1; Fig. 5 is a horizontal sectional view take on the line 55 of Fig. 4; Fig. 6 is a plan view of the feed throw; out control; it

Fig. 7 is an elevation view of the feed throw out control; 1

Fig. 8 is a detailed horizontal sectionalview taken on the line 88 of Fig. 4.

Referring to the drawings, Fig. 1 shows a porttion of a web treating machine which maybe a printing press or a paper fabricating machine in which the web perforating mechanism is used to perforate the web at spaced intervals so/gthat these perforations may cooperate with parts of the press or machine to secure proper reg i'stery of the web for printing, cutting, or other sub sequent operations.

A rotary punch roll I having radially disposed punches H mounted therein is keyed to a shaft I2 journalled in the frame I3 of the machine and carrying a gear I4 which meshes with a gear Ia (a part of which is shown in Fig. l) on a shaft I5 which is driven by any suitable drive connections with a motor (not shown) so that both shafts I2 and I5 are positively rotated.

The shaft I5 is journalled in the frame I3 and has an anvil roll I6 keyed thereto and provided with an annular ring or facing I! of lead, copper, brass, soft steel, rubber, or other suitable composition material, softer than the punches, H with which it cooperates, and preferably one which may be ironed smooth in case it becomes roughened by the action of the punch roll. The ring I! is removably mounted on the roll, I6 by a tapered flange connection I8 with the roll itself at one end and a similar connection I9. at its other end with a collar clamped to the roll I6 by a spanner type sleeve nut 2| (see Fig. 5).

A doctor or ironing roll 22 is rotatably mounted on a shaft 23 whose ends are carried in the ends 24 of a pair of arms 25 whose other ends 26 are mounted on a shaft 21 having. eccentrical- 1y disposed pin ends 28 mounted in the frame I3. The ends 24 of the arms have cylindrical bosses 29 disposed eccentrically of the shaft 23 and mounted in the outer ends 30 of a pair of arms 3I Whose lower ends have ball bearing journal mountings 32 on the shaft I5. With thisconstruction turning of the shaft 21 will act to swing the ends 24 of the arms 25 to shift the eccentric bosses 29 in the arms 3| and thus shift the shaft 23 with the roll 22 nearer to or farther away from the shaft I5 whereby the roll 22 may be brought into pressure contact with the facing I! of the anvil roll I6 to produce an ironing or smoothing effect thereon as the shaft I5, is revolved or said roll22 may be moved out of contact with said'facing I1. and 3, one end 28 of shaft 2! has a hand crank 33 secured thereto for turning said shaft to shift said roll 22 as above described. Forlocking the shaft 21 in any desired angular position, the crank 33 has an arcuate slot 34 in which a clamping bolt 35, mounted in the frame I3, works, said bolt having a hand projection 36 for turning it to bring its head into clamping engagement with said crank.

For web feeding in or threading through purposes, the shaft I5 is mounted in bearings'3l which are capable of eccentric adjustment in the frame I3, one of said bearings having a slotted crank arm 38 whose slot is engaged by a pin 39 on one arm of a lever =40 secured tothe end Referring to Figs. 2v

of a shaft 4| journalled in the frame. The other arm of the lever 40 carries a crank handle 42. Swinging of the lever 40 in one direction causes an angular movement of the arm 38 and the bearing 31 in the opposite direction, and because of the eccentric mounting of said bearing, the shaft I5 with the roller I6 is moved toward or away from the punches II on the shaft l2 dependingupon the direction of swing of the lever 40. For fine angular adjustments of the bearing 31, the lever 40 has a post 43 mounted to swivel thereon and forming an abutment for an adjustable stop rod 44 that extends loosely through a hole in said post and has a stop shoulder 45 adapted to engage said post. The stop rod 4 4 is threaded at 46 to engage a threaded hole in a boss 41 pivotally carried by the frame F, and it carries a handwheel operated lock nut 48 and a handwheel 49. Turning of the stop rod 44 by the handwheel 49 moves said rod L relative to said boss 41 and the lever 49 and hence the stop shoulder 45 relative to the post 43 so that the extreme inward movement of the anvil IE relative to the punch rollmay be definitely determined'and so that the punches I I will in most cases have a kiss touch with the anvil so as to makes. clear cut through the web, it being noted that the punches I I are either hollow punches or solid punches with concave heads as indicated in section in Fig. 4. After the stop rod 44 is adjusted, it is locked in its adjusted position by lock nut 48. The lever may also be locked in its desired adjusted position by a lock bolt 49 provided with a crank 50 and working in an arcuate slot 5| in the lever 40, said bolt having a threaded connection with the frame and its head adapted to clampingly engage said lever. 0n the movement of the lever 49 to an anvil throw position said lever with its post 43 is free to move away from the shoulder 45 with the rod 44 sliding freely in the post 43.

With the above description of the parts, the action of the perforating mechanism will be readily understood. First, the anvil I6 is thrown out ofits operative position relative to the punch roll I I! by upward swinging of the end of the lever 40, and the web of paper or other material to be perforated is threaded through between the roll I0 and anvil I6. The lever 40 is then swung back to bring it in contact with the stop 44 and locked so that the facing II then is positioned in proper relation with the punches II. The machine is then started, and as the shafts I2 and I5 rotate, the punches I I perforate the travelling web. The spacing of the punches II relative to each other about the circumference of the roll I0 is such as to secure the desired lengthwise spacing of the holes or perforations in the web and may be varied to suit the character of the registry mechanism through which the web subsequently passes.

With the above arrangement the punches I I do not have to be timed relative to a cooperative die member to get the proper punching action. All that is necessary is to adjust the anvil I6 in proper relation to the punches II to secure efficient cutting action of the punch and where the anvil facing is of metal, the doctor roll 22 may be moved,

into pressing or smoothing engagement with the facing I! by the angular adjustment of the shaft lit) but new facings Il may be placed on the anvil roll l6 from time to time when found necessary for the proper operation of the punch. It has been found that when using a metal facing H on the roll it, the punches II are virtually selfsharpening as their cutting efficiency seems to improve under continued use.

It is to be noted that the shaft 21 with its adjusting crank 33 has not been shown in Fig. 6 so as to more clearly show the adjusting mechanism for the shaft I5, but said shaft 21 with its adjustment has been shown in Figs. 1 to 3.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except insofar as such limitations are included in the claims.

What I claim as my invention is:

1. In web perforating mechanism having a pair of rotatable rolls between which the web passes, shafts for said rolls, one of said rolls provided with radially disposed punches, the other roll being an anvil roll having a relatively smooth punch contacting surface of deformable metal. the combination of an ironing roll contactable with said surface to iron out deformations therein, a shaft for said ironing roll, a rigid but shiftable tie means connecting the anvil roll shaft with said ironing roll shaft, an eccentric mounting for said ironing roll shaft in said tie means, manually adjustable means for varying the eccentricity of said mounting to bring said ironing roll into and out of contact with said anvil roll, and means for locking said adjustable means in an adjusted position.

2. In a' web perforating machine having a pair of rotatable rolls between which the Web passes, shafts for said rolls, one of said rolls provided with radially disposed punches, the other roll being an anvil roll having a relatively smooth punch contacting surface of deformable metal, the combination with an ironing roll contactable with said surface, of a shaft for said ironing roll, and means for moving said ironing roll into pressing contact with said surface of said anvil includin oscillatory arms having bearings at one end in which said ironing roll shaft is eccentrically mounted, rigid tie means pivotally mounted on said anvil roll shaft and carrying said bearings, and means operatively connected with the other end of said'arms for angularly adjusting said eccentric bearings and simultaneously shifting said rigid tie means to move said ironing roll toward or away from said anvil shaft and relative to said tie means.
