The invention relates to new and useful improvements in sheet folding and delivering mechanisms, and more especially to such improvements in said mechanisms adapted 3 to fold and deliver running webs from fast rotary perfecting printing presses and the like.

Objects and advantages of the invention v will be set forth in part hereinafter and in lo part will be obvious herefrom, or Vmay be learned by practice with the invention, the same being realized and attained by means of the instrmnentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, construction, arrangements, combinations and improvements herein shown and described.

rlie accompanying drawings, referred t 2Q herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description serve to eX- plain the principles of the invention.

.The invention is directed to mechanism especially capacitaed to cut and fold olf the sheets, or groups thereof, collected or uncollected, from very fast running webs, for

instance, the perfected and longitudinallyr being preferably of reliable and tested design and operation, thereby insuring reliability of operation, absence of stoppages and brealrages, and other faults, while maintaining the desired high speed of product output.

Referring in detail to the embodiment of the invention illustrated by way of example in the accompanying drawings, a cylinder l is shown provided with sheet cutting, sheetholding and releasing, and sheet-folding mechanisms, and a cooperating cylinder 2 is provided with like devices. These cooperating cylinders and their attendant mechanisms are capacitated to take the running webs' from the printing press or other source of supply, to cut same into sheets and either to fold the cut-off sheets alternately from one cylinder and its folding mechanism and then .rom the other cylinder and its folding mechanism, or to collect on one of said cylinders.

and to fold off therefrom the entire product from said source of supply into a single folding mechanism. In the application of the present vinvention to fast rota-ry perfecting printing presses, the perfected webs, usually four pages wide, are centrally slit, the two halves being run over a pair of formers, and hen directed to the two cylinders to be operated on in one of the alternative ways as already described. It will be understood that other sources of'web supply may be provided as may be desired.

. In said exemplary embodiment, a cylinder 1 is provided with a shaft 5, and suitable supporting heads 6, the shaft 5 being journaled inthe side frames? at eith'ersivdepf the pressi Y Said cylinder as embodied is a three-way'cyle inder, that is, it has three sheet-carrying surfaces arranged about its periphery. The cylinder is provided with suitable sheet-cutting devices cooperating with corresponding devices upon the cylinder 2. As embodied, the cylinder 1 has three female cutting members ,12, 13 and 111. In this present embodiment the diameter of thecylinders 1 and 2 is in the ratio of three to two, and accordingly the cylvso ' 40. nismfor for the collecting and folding olf of inder 2 is provided with two cooperating `the'web yimmediately after the sheets are cut in the'usual manner. In each ofthe impaling pin devices, the series of pins are mounted 1n a bar 26 carried upon arms 27, fixed upon l a shaft 28, the shaft-"28 being j ournaled in the heads of the cylinder 1. The shaft 28 projects from the cylinder head at one end, and on the projecting end of the shaft is fixed an arm 29,upon which is mounted a'cam roller 30 which runs on the cam for timing'the operation of the pins to take and to release the sheets in proper time, either for the alternate folding olf arrangement of the mechathe entire product by the cylinder 1. On the actuating mechanism for impaling pins 22 the` samevreference numerals are applied with ana, and for pins 23 ra b is added. rllhis variable setting of the'timing and operation of'theimpaling pins is controlled by a rotating cam mechanism', which will be later described. l

Thecylinder2 of theV present embodiment is provided with only one set of sheet-tak in holdin vand releasing devices shown as a set of impaling pinsV 33 mounted upon al bar 311, Awhich bar is carried upon arms 35, fiXedto a shaft 36 journaledin the heads of the cylinder. One end lof the shaft projects'. from the cylinder-86,. and attached theretois an actuating arm 37'` which carries a cam roller 38, Vwhich cooperates y with a controlling cam vmechanism laterftobe described. Said mechanism isconstructed and :arranged so that the set of impaling pins j may beoperated each time they come to sheetcutting position, Vor may be totally silenced.

Forjthis purposea disc 40 isiixed on the end `of shaft 36 and arm 37 ext'endsfbeyond the vupon the cylinder 2, has no cooperating set of Yimpalmg pins, as consecutive sheets are not taken from the ruiming webs upon cylinder 2 as thegmachine is here exemplarily organized.

yThe embodied form of `folding 0E mechavnisms upon cylinder 1 comprises a plurality of single-edge rotatable folding blade mechw nisms, one set being located' at each Lof the sheet-holding surfaces on the cylinder. The folding device Ll5 hasa single folding blade 46'mounted onl a shaft l?, which shaft is journaled in the .cylinder heads. The shaft 47' has one endv projecting from the cylinder 1, and fixedto said shaft end is a crossbar 48, carryingV cam rollers 49 and" 50 at either end thereof. rlhese cam4 rollers run on a circularV track 51 of the kind commonly used with the so-called Husby cam movement.

The folding mechanism 55 has a single folding blade 56, mounted on a shaft 57, which is journaled in the cylinder heads.

Onthe end ofV shaft 57 which projects from the cylinder head isy mounted al cross-bar 58, at the ends of which are mounted a pair of cam rollers 59, and 60, which likewise runon track 51, and `are "actuated by the rotating f caml at the folding position. ln

like manner, folding mechanism has a single folding blade'66, fixed on a shaft 67,

j ournaled in the cylinder heads. To the projecting end of the shaft 67 is fined cross-k varm v68, 'on which is mounted a pair of cam rollers 69 and 70, which'likewise run on the cam track 51 and-coact with the rotary cam at the folding-off position. y c

' The rotaryactuating cam,'- as embodied,

comprises la cam' disc 77 fixed to and rotating with a stub shaft 78, mounted on the machine frame. Thek cam 77 is provided with two cam slots 79 and. 80,' whichl cooperate with the cam rollerson the folding devices, these cam' slots being arranged insubstantially tangential relation to a circle concentric with the cam shaft. The cam is rotatedby a gear 81iiXed thereto, which meshes with a gear 82, iixedon the shaft 5 ofthe cylinder 1.

The cam has a three-to-two Vratio of revolutiontothey cylinder,V and therefore actuates each ofthefolding mechanisms each time that it passes thecam. l

Cooperating with-the folding blades `are a pair of folding-0E rollers 85 anidr86, which v'.areshown more or less conventionally, and

v86, rand same is indicated generally in Fig.

" rollers.

1 of the drawings by reference numeral 87. 1t may comprise a star wheel and a delivery belt of the usual or common form.

The folding mechanism 91 on the cylinder 2 is double-bladed, having two blades 92 and 93 fixed to a shaft 94, which is journaled in the cylinder heads. On the end thereof which projects from the head of the cylinder 2 shaft 9--.is provided with a crossbar 95 at the ends of which are mounted cam rollers 96 and 97. These cam rollers run on a fixed circular cam track 98. Cooperating therewith is the rotary cam 99, mounted on the shaft 100, journaled on the machine frame. Fixed to the cam disc is a gear wheel 101 which cooperates with a gear wheel 102, fixed on the shaft 103 of cylinder 2, which latter shaft is journaled in the machine frame. The cam is provided with three cam slots 104, 105 and 106, which are tangentially positioned in the manner already described. Cooperating with the folding mechanism in the cylinder 2 are two folding- od rollers 109 and 110, which are adapted to deliver the folded papers to a rotary delivery mechanism indicated generally at 111, which may comprise a star wheel and traveling delivery belt of known form. The cam 99 makes four revolutions for three revolutions of the cylinder 2, and actuates the folding mechanism every time it passes the folding rollers.

As regards the operation of the folding mechanism when. running straight, that is, when one group of sheets cut from the running web is taken by and is folded od from cylinder 1, and the next group is taken by and folded olf from cylinder 2, the mechanism mai;v be regarded as in the position or Fig. 2, and the web leads having been taken by the impaling pins 23. Vhen the folding mechanism 65 reaches the folding- olf rollers 85 and 86, it is actuated and the folding blade folds off the sheets between the folding The next lead of the web is taken by the cylinder 2, in a manner hereafter to be described. r1`he impaling pins 22 of cylinder 1, therefore, do not take the web, but pass the sheet-cutting position retracted within the cylinder.

l/Vhen the folding mechanism 55 reaches the folding-off rollers 85 and 86, the folding 'mechanism is actuated, but due to there being but a single folding blade, the folding blade 56 at this time moves within the cylinder during the semi-rotation of the shaft 57, and there is no'folding-off action, which is proper, as there are no sheets on the section. vThen the folding olf mechanism reaches the folding position, it is actuated and the folding blade 1-6 folds olf the sheets in the rf'sual manner. When folding mechanism 65 next reaches the folding position, it is actuated, but the folding blade 66 rotates within the cylinder, and there are no sheets on this section of the cylinder, and therefore no folding od. Vhen folding mechanism next passes the folding position it is actuated and folding blade 56 folds ofi the sheets from the cylinder. 'Vhen folding mechanism 45 again passes the folding position it is actuated, but the blade 46 rotates within the cylinder and there are no sheets on the section and therefore no folding off. This completes one cycle of operation of the folding mechanism.

T he folding mechanism is the same whether the mechanism is run straight 0r collect. ll/hen the mechanism is run straight, every other group 0f sheets cut from the webs is delivered to cylinder 2 and every alternate sheet supporting space on cylinder 1 consequently passes the folding position vacant and this corresponds to the non-folding actuation of the particular folding mechanism. Vxlhen the machine is run collecting, and all the products are taken by and folded off from the cylinder 1, the non-folding actuation of each folding mechanism corresponds to the collecting period for the particular sheet supporting section. That is the first group of sheets is carried past the folding position, and the second group of sheets is taken upon the first group, and as so collected, they are folded offl together on the neXt passage of the folding off rollers.

Referring now to the folding-olf action of cylinder 2, it may be considered that the impaling pins o3 are in the projected position and are carrying a group of sheets, as the folding mechanism 91 comes to the foldingoff rollers 109 and 110, the impaling pins 33 are retracted, and the sheets are folded off by either folding' blade into the bight of the folding-off rollers 109 and 110. rPhe next time the impaling pins pass the sheet-cutting position, they are retained in the retracted position, and do not take the lead of the web, which has been taken by one of the sets of iinpaling pins on the cylinder 1, and on this half rotation the folding mechanism of cylinder 2 is actuated idly.

Referring now to the embodied form of means for timing and actuating the iinpaling pia mcchanis is on the vlinder 1 1,

3, S and 9), rol ers 30, 30a and 30h of the respective nnpaling pin mechanisms f l. 11 P1 run 1n a rotatable ore cam 121. uam 121 is integral with oL nr. d to a gear wheel 122,

mounted loosely on sli-ait- 5 of cylinder 1, and

grt running or to 'v-fhcc 12) is l Xeo. on shaft meshes with the loose gear wheel 122. laterineshing gear wheels 121 and are fixed, respectively, on the shafts 5 and 103, to cause the two cylinders to rotate together in the required three to two ratio. The gears 122 l li nner 2 to turn therewith, and

v and 123 are proportioned to effect the rel quired relative rotation between cam 121 and cyhnder 1, and therefore the nnpalin f piny are@ runs (Figs. ,8) the cam makes three revolutions to'tWo revolutions of cylinder 1 and in the saine direction. lmpalingfpins A (which maybe any lgiven set of pins) are in the pro- `iected/ position and take therweb lead at a" on the cam. The pins A then rotate 150 to Y the point Y, Where they are retracted into the Y cylinder .to rel-ease the sheets, which at that Y Lion the cam, which is 7 5 behind thepinsy instant are cut foil" and yfolded into the lolding-offrollers 85 rand .86. Thel low point A. `edlen. in the position of Fg- 8 (that is When taking the Web lead), rotates 225 While the pins A are rotating 150 from a; to 1.1/ (that is from sheet-taking to sheet-releasingpositions), and thereby the cam roller M for the pins A and the low L on the cam coincide at Y and the pins are retracted, thereby releasing the sheets as they are folded off,

Vhenthe set of pins B are at position A, they must be retracted Within the cylinder,

. as the lead ofthe Web is then taken by the impaling pins on cylinder v2. 40

The rotation of pins B from the position of Fig.f8 to posiion A is 120, and during this rotation ot pins B `from the lposition of Fig. 8 to position oit' Fig. 8, anpdthis puts the low'side of the cam at position A, and lpins B are thereby retracted. Withinthe cylinder and do not take .the web head.y

VWhen pins YC have reached position A,

l they must project, as cylinder 1 again takes 'the'web lead as was the case With pins A.

The rotation of the pinsfrom their position kin Fig, 8 to positionrA is 240, and Vduring this rotation they cam rotates 360 (and is4 n thus again in the position shown in 8f), and pins C are projected andv take the lead ot the web. f The entire cyclethenrepeats with the pins C, in the manner already described with relation to pins A, and` later the saine y, thing occurs With respect to the pins B.

Thus, everyalternate time the Web lead is vtaken by cylinder 1 and on the other time by cylinder 2, the folding-ott7 occurring as has already been described.

VConsidering now the machine asset/for collecting by cylinder 1, the interchangeable split cam shown in Figs." 4 and 8 has been h'ayingcorne up to this position bare afterY the collected product: has l been folded ofi. At this time pins Bh'ave one sheet or group, andgwill take another sheet or group there- `on When position A is reached. The pins C are Just about to release the'collected product vat the instant ot folding-oli. f

Pins A are projected at position A of Fig.v

9, and must stay out during one `complete Vrotation ofcylinder 1, to i'mpalel the web lead Which is just being taken in Fig. Sland to then again impale the Web lead to collect the second rsheet or group upon the i'irst, and must remain lout'v untily point Y lis reached, where the Apins :must be retracted to release the collected product .atl the instant of folding-oli". The complete rotation of the pins A from the point of taking the first web lead, past the taking of the second Web lead, ,and to the position Y 'with the collected product is 510, and the` camrotates during this time 765'. Thus the lowpart L ot the cam and the actuating roller for the pins A coincide atthe point Y, and thereby the pins A are retracted, and the collected product folded ott. f

PinsB` must yproject beyondv the cylinder untilthey reach point A to take vthe'second web lead tocomplete the collection of the two products, and must continue projected until they reachthe point Y. Y At that pointthey must be retracted kWithin the cylinder to release the collected product at the instant of folding-olf; TheV rotation of pins B from the Vposition shown in Figa9, tothe point Y is 270, ,andv duringthesaine time the cam rotates from the position shown in Fig. 9,

through 405, which bringsthe low L ofthe caintothe point Y coincidentally with the actuating roller.. tor the pins B,,Which are retracted and the collected product is folded 0E.`

shown in Fig.`9 through 30 yto the point Y,

and during that time the vloWVpoint L on Pins C must rotate from the position 'li CIJ and the collected product is'V folded of. 'The 51"? sequence then begins againwith pins A.

It Will be understood that-theplates will be positioned on the oppositehalvesot the form cylinders of the vvarious,.printingcouples SO as to 'get Properly 'fOldedproduct T11 at either delivery.` f
