CARL A. E. OLSON BY ATTORNEYS to the cylindrical body; and:
. w 1 noraitv'currmomsaivs FoacoLLAr sc MACHINE certain spacing will therefore occur between the forms of twothirds of an inch. Mostof the forms printed in thisfashion are multiple forms, that is to say three or more carbon copies are made from a standard form and thus a number of identical cylindrical rolls of printed material are produced usually on different colored paper The cylindrical rolls of printed materials are then passed on to a collating machine where carbon is inserted between different webs of the printed material and it has been usual, as the webs are joined together and pass into their justifyingstage, to be severed by a rotary cutter. The rotary cutters that have been used in the past have consistedof a single knife or perhaps two knives mounted within recesses in cylinders and secured therein by nuts and bolts. The design of these cutting cylinders have long been known and are exempliiied inULS. Pat.No. 877,0l of 1908. Since the printed forms have to be made to a particular size andcannot be accurately cut. unless perchance they are 8% inches long which divides equally into the 17-inch repeat of the rotary web press drums, an additional operationis necessary by. stacking the forms and putting them into a vertically reciprocable cutter. When this is done, it will be realized that carbon paper is in a between the leaves 'of the forms andv as the. cutter blade descends the carbon will deposit itself onto the layer below and leave a carbon edge showing where the form was cut. This is an undesirable result in the production of forms and the present invention. obviates this by providing a cutter drum which can be readily. utilized with any size formandwill cut the necessary scrap between the repeats of the printing material as the same passes out of the collating machine.
SUMMARY or THE INVENTION holesare spaced. around the circumference. of the-cylinder in" positions whichzwill mount: theblocksthat support the cutting knives at positions toaceommodateS-irtch, 4-inch. -inch and. the like-sized forms, and are also spaced about the circumference distances toaccommodate notaonly the. standard'l7- inch circumferenceprintingproll press but also the l4-inchand the 22-inch circumference roll presses that aresometimes found used inatheprinting industry.

FIG. 4A is a sectionalview similar to FIG. 4 showing one cutter.
DESCRlPTlON OF THE PREFERRED EMBODIMENT In the form of the invention that has been chosen for the purposes of illustration'in. the drawings. the rotary cutter of the invention is shown as embodied in a collating machine which is made up of a plurality of web intermediate units generally designated 12. Some of the intermediate units contain rolls of printed paper webs 14 and 15 for example, and a roll of carbon paper l6 that are interleaved with the carbon paper web in between the webs from-the rolls 14 and 15. To this end. therefore, the roll 14 has a web 17 emanating therefrom and the roll. 15 has web 18 emanating therefrom and the carbon paper roll 16 has a web 19 emanating therefrom. These three are combined in what can be termed a strip of material generally. designated 20 that passes over the combining conveyor table generally designated 21 by being fed by rolls 22,23 and to a cutting unit generally designated 25. Here the cutter roll 10 of the instant invention is mated with an anvilcutting cylinder 26 against which the knives of the cutter cylinder 10 are adapted to be pressed to sever the webs.
The cutter cylinder 10 is illustrated in the drawings and more particularly in FIGS. 2 and 4 as taking the form of a cylindrical body which is provided with trunnions or a drive shaft such as 28- that is rotatable about an axis parallel to the axis of rotationof the shaft29 of the anvil cylinder 26. A knife holder generally designated-30 is secured to the cylinder 10 by means of a plurality of socket head screws 31 that pass through a knife mountingblock 32' between its opposite knifemounting faces andinto openings 33 in the cylinder. The surface of the block 32 engagingthe cylinder may be arcuate to fit the cylinder. The opposite faces 37 of the block 32 are formed on a radius of cylinder 10. The knife blades such as 34 are in face to face engagement with .face 37 and will be mounted by means of clamping plates35 and screws 36 so that they extend radially outward from the cylinder. in the illustrated embodiment there has been shown a pair of knives not only the knife 34' but also a second knife 38 that is mounted on the opposite side of theblock 32" having a face which is a radial of the cylinder 10. it is quite common in the industry today to have whatisknowntas snapaway forms that are 7% inches in length. As stated-before, theusualtype of rotary web press printing rollhas a circumference of 17 inches. Accordingly. for the production of a number of forms, there will be two repeats per revolution"of'the -printing roll. This means that there will-be scrap materialto be cut off in order to maintain the proper dimensionalshapeof the'form-of 1% inches. Two cuts have to be made, however, andtherefore, i4 of an inch scrap have to be cut offbetweeneach of the forms. Accordingly, it is customary to form the: block 32 of such'a dimension that the knives and 38-at their cutting edges will be% inches apart, and. if two such-cutting blocks are-placed diametrically opposite each other, itwill bereadily seen as the forms progress through thecutter of the'collating machine, that the'scrap or theportion between'the formswhich is unnecessary in the entireweb willbe completelycut'outandwillpass-down on the forwardsideofthe cutting; arbor as at 40 into a waste area. The ejection of the. scrap is assisted by resilient members 41 locatedbetween the-knives'34; 38% Normally so-called-trim disposals units'are providedoncollating machines, and they will suck out thescrap paperand dispose of the same in the usual fashion; in this 'way', it can'bereadily appreciated that on the delivery table 42? proper size formsare produced which need only be properly stackedupdnto shipping containers or banded for shippingz'as the case' mightbe without any further operation beinghad thereon-tomake the same marketable sizewise. I
It will be readily appreciated that in many instances it is not necessary to cut out any strip of material to make the forms the proper size. Accordingly. in many instances where forms of 8% inches length are produced, a single knife only is necessary and in this case a single knife may be mounted such as shown in FIG. 4A. and should any spacing of the knife be necessary to provide a certain point of cutting, a wedge such as 44 may be placed between the mounting block 32 and the pressure plate 35 to accommodate for this size variation. By referring to FIG. 3 it may be seen how a variety of arrangements can be achieved by providing a plurality of holes that are predrilled in the cylinder such as the hole 33 on the cylinder l0. These holes can be prearranged at certain angular positions and knowing. for example. that it is common to produce certain angular positions and knowing, for example, that it is common to produce certain sized forms. For example. a 5-inch form is a common size form, and ifa S-inch form is to be produced. the cutting blades would be oriented generally on the radial lines indicated at 50 in FIG. 3. These are l apart and will make three cuts from a 17-inch rotary web plate with a pair of knives such as illustrated in FIG. 4 that are spaced apart of an inch at their cutting edges. Any number of combinations are possible with a mechanism of this configuration. and by properly coordinating the rotary web press printing cylinder with the cutting cylinder of the collating machine. any and all combinations may be possible since in some cases the adjacent forms may be juxtaposed in such a way that only a single cut is required at one point while a double cut is required at another point to remove the waste scrap that is produced by the spacing necessary in order to utilize the l7-inch circumferential dimension of the printing cylinder.
