14 Claims.

This invention relates to improvements in paper feeding, cutting and registering mechanism.

The main objects of this invention are: First, to provide a paper cutting, feeding and registering mechanism which is well adapted for delivering paper in the form of sheets to a printing press in registering relation thereto.

Second, to provide a machine or apparatus for feeding paper from a roll to a cutter and from the cutter in side and end registering relation to a printing press or other machine.

Third, to provide a machine of this character in which the paper may be readily adjusted for cutting and delivering of sheets of considerable variation in length.

Fourth, to provide an apparatus of this character in which the sheets are out to very accurate lengths and are delivered in accurate register.

Fifth, to provide a structure embodying these several advantages which is comparatively simple and at the same time positive in performing its functions of feeding, cutting and registering delivery.

Objects relating to details and economies of the invention will appear from the description to folfunctioning relation, and various parts being shown mainly in conventional form.

In the accompanying drawings, I represents the frame of a printing press, 2 the impression cylinder, 3 the type or printing cylinder, and 4 the transfer cylinder for transferring the sheets from the registry table or bed 5 to the impression cylinder. The transfer cylinder 4 has a registering stop 6. The sheet grippers or other pickup means of the transfer cylinder are not illustrated as they form no part of this invention and are understood by those skilled in the art to which the invention relates. The stop 6 is adjustable and suitable means for effecting this adjustment are likewise known in the art and are not shown. The frame 1 is designed to support various moving parts to be described. Side rails 8 extend between the frame of the printing press and this frame 1 and support the feed bed or table 5. The frame 1 is provided with bearings 9 to receive the roll supporting spindle H] of the roll of paper II. The web of paper is provided with a suitable brake or drag means not illustrated. The paper is drawn from the roll II and delivered into a loop l2 by a paper feed unit comprising the coacting feed rollers 13 and 14, the feed roller l3 being the driven feed roller and the roller 14 being a pressure roller. In the embodiment illustrated the roller I4 is in the form of a plurality of wheels having rubber rims l5. The shaft I6 of these pressure wheels is carried on arms I! on the transverse rod l8. Arms IS on this transverse rod l8 support the thrust springs 20.

From the loop I2 the web designated by the numeral 2| passes over the aligning guide 22 to the second feed unit comprising the driven feed roller 23 and coacting pressure roller 24 which is desirably of the same structure as the pressure rollers described for the first feed unit. The feed roller 23 is provided with a shaft 25 having a sprocket gear 26 while the shaft 21 of the feed roller 13 is provided with a sprocket wheel 28. The shaft of the pre sure rollers 24 is carried by arms I! on the transverse rod-29 corresponding to the rod l8 and. has the pressure means as described for the firstunit.

The web is advanced by'the second feed unit to the coacting rotary cutters designated generally by the numerals 3| and 32, these cutters being provided with shafts 33 and 34 positioned at an angle to the path of'travel of the web as shown in Fig. 2. The rotary cutters are provided with disk-like end bearers 31 and axially spaced feed disks or bearers 38. The bearers 31 are of the diameter of the meshing drive gears 39 on the It will be noted that the gripping portions are disposed in angularly stepped relation aboutithe rotary cutters. tion illustrated, which is a commercial embodiment, the knives are disposed at an angle of approximately one and one-half degrees angular.

relation to the axes of the rotary cutters or cylinders and are set at the same angle so that the knives start cutting atone edge of a web and make-;a'.-'smooth cut-across the-web, the result beingastraight right-angled out across the web. The gripping'segments, are. of such length asto grip-1theweb from the beginning tothe end of the cutso; that there'is, no relativeslippage; The leading. edges of the-gripping segments' 4e and M will first-gripthe webas the segments are rotated into-coacting;relationship;on opposite sides of theweb; As rotation of the-cutter progresses and the-knivesarebrought intolapping shearing engagement;.there-wi1l*be some, depression of the leading portion of'th'e resilient gripping segments ahead of the blades by reason'of engagement .of the. lower blade with the resilient gripper, ahead of; the1:upper-.-blade as; is illustrated in: Fig-l 5; However;before-retraction-aor compression-of the leading portion ;of the resilient gripper has progressedsufiiciently to release thenewly severed portion of. the web, the rear trailing portion of the resilientgripper will have-moved into gripping-relation with-the web behind the blades.

At therearof the cutter-unit I provide a sheet feed unitwhich also serves to support the end of the .web at the rear of the cutter'unit during thescutting operation This unit comprises the feed -rollerg42 mounted on theshaft 43-and having a,-driving-connection therewith; The coact ing-pressure roller 44 isof therubber tired wheel type adescribed for the previously described feed unitsand its shaft I44 is-carriedby arms 45 on therockshaft 46;-

Thissheetfeed unitis mounted on-supports-or slides-4l adjustable longitudinally of the side rails 8, the side rails being slotted-at .48 toreceive the. clamping bolts 49 by means of which'the supports; or slides are secured intheir adjusted positions. As the'cutter begins-making abut. the pressure wheels are lifted: from pressure con.- tact-.withtheweb. Thesmeans for doing this in the embodiment illustrated comprises the cam 58 on the-shaft 34 of the lowerrcutter cylinder, this camtcoacting witha cam follower roller 5! on; the-levery52wwhich is connected by the link-53 toitheearm. 54 'on..the;rockshaft .46. Thespring 55 :holds:the follower "againstthe cam and serves to: lif-ti thexpressure 3301161? "when it :is released: by the cam. The length of.jthe=.linki:53;.is adjustable asza-t '553A to; accommodate adjustmentsv of the slides '41 of-rthe feed unit.

To'prevent any unduestrcss onzthe. web while it: is engaged; by thegripping segments the 7 sprockets. wheels $262011: thesfeed" rollerishaft' 25 are-desirably provided-with:anoverrunning clutch which may-be :of :the roller: type illustrated in Fig: 6: The control of the pressure roller "44 is.

suchzthaton-th'e completion of the cut and release .75 web is moved transversely, the pressure ro1lers58 In the embodiment of the inven of the web by the cutter the pressure roller 44 is brought into contact with the cut sheet which is advanced on the feed table 5 until its edge contacts the feed roller 58 of the delivery and registering unit. This feed roller 58 is driven at a slightly higher circumferential speed than the transfer cylinder 4.

The driving connections illustrated. include the sprocket 56 on the shaft 51 of the roller-58 which is connected by the sprocket chain 6!! to a sprocket 6[ on the shaft 43. The shaft 43 is provided with a sprocket wheel 62 which is connected by the sprocket-chain 63 to the sprockets on the feed roller shafts Z5 and 21. One of the gears 39 of @the rotary cutter is connected by an intermediate gear. 66. to. a gearfil on the shaft 43. Primary driving energy is delivered to one of the gears 39 from asuitable source, not shown. To vary the length of the sheet cutja gear 66, which meshes withgearfilzwhich drives asprocket at 62, which drives-.asprocket. at 28 (Fig-2) .on the feed .rolll3 can be changed to another gear fifihaving a differentnumber-ofteeth thereon, if the shaft on which gear-fidismountcd is'madeadjustable as to position..onthe frame-.- This will .eifect a variation in the feed of-theweb and so vary the lengths cut by the'uniformly driven cutter: roll. The'roll 58 has a resilient or yielding; face 59:

Feed pressure ball 68 are provided to coact with the roller 58, these balls being rotatably supportedrinholders filcarried on. the cross member 'Mkmountedon the side rails 8; These pressure rollers permitlateralshifting ofthe sheet as well as the feeding thereof. As the sheet engages the feed roller58 it is.drawn.out; ofcontact with the feed roller tizand, coactin pressure-roller 44, a portionof the sheet'being supported by the table. At the rear of the roller 58 I provide a suction registering means comprising the shaft H which is connectedv by the gears 1'2. and the 1 meshing gears 13 tothe'shaftfilof the-roller 58. This shaftfll -is mounted for axial movementand is provided with a yielding faced sheet supporting roller. l4;

At. eachend of. this roller Ml provide a suction drum B5,:thes suction drums beingfixed to the shaft and each having a peripheral series of suction holes lfi preferably arranged in staggered relation. These suction drumsembrace the suc- 0 tion heads H which are non-rotatably mounted onbrackets 'lficarried bythe cross piece 10. The suction :heads have restricted recess-like chambers F9-with which the suction holes of the drums are successively brought into register as the drums rotate. Thesuction heads are connected by flexible hosetothe branch pipe-8| connected toqasuitable-source of vacuum, as the vacuum pump 82 shownconventionally in ,Fig, 2. The pipe or conduit 8! is providediwith. a solenoid controlled ,valve 83 also shownconventionally in The-shaft ll, being supported for axial movement, in its bearings-84, is actuatedto laterally registenthesheets, and;.this is in timed relation to'theirotationofthe tr.ansfer.:cy1inder 4. The meansrillustrated. for; accomplishing this. comprises a cam 85 on theishaft '86 .ofzthe transfer cylinder, this-camcoacting with a lever 81 providediwith'a'roller follower 88. The lever is connectedcbythe link89ltoone arm of the bell crank lever 90 pivoted at 9|, theother arm .of the lever being forked to: engage the'shiftin collar 92 of thershaft Tl As the .suction feed rolleris shifted'axially, the

- permitting this shifting without undue stress on the sheet or wrinkling of the sheet. The shifting of the sheet laterally brings it into contact with the switch actuating arm 93 of the switch 94 shown conventionally in Fig. 2, the connection for the switch to the solenoid actuated valve 83 being conventionally shown at 95. The sheet is advanced against the positioning stop 6 of the transfer roller and thus properly registered longitudinally, and at the same time is shifted laterally and properly registered transversely.

I have illustrated an embodiment of my invention as I have adapted the same for feeding and registering in a printing press. My invention however may be readily adapted for use in other relations or in other paper conveying machines Without bringing the sheets to a stop as is usual in a conventional paper feeding and cutting mechanism. Various parts are illustrated more or less conventionally in the accompanying drawing and I have not illustrated the source of power. This may be applied through the gear 12, for example, or through a pulley provided for the purpose on the shaft H, or through one of the gears 39.

I have not illustrated or described the various adaptations or embodiments of my invention contemplated as it is believed this disclosure will enable those skilled in the art to adapt my invention as may be desired.
