INVENTOR JOSEPH S- RISICA BY N41 64's ATTORNEY United States Patent 3,242,781 FORMER FOLDER Joseph S. Risica, Westerly, R.I., assignor to The Cottrell Company, Westerly, R.I., a corporation of Delaware 4 Filed Oct. 7, 1963, Ser. No. 314,329
3 Claims. (Cl. 83-107) This invention relates to a former folder arrangement for use in connection with rotary web printing presses. Y
N'ational'mag-azines currently contain advertising matter directed toward specific areas of the country, so that a magazine. issue must be broken up into regional matter applicable to that region.
-This' makes it necessary, on a press printing three successive signatures, to print and deliver three different signatures, separating them so that they may be introduced into the bindery in the proper regional divisions of the issue.
A' folder constructed according to my invention is capable of delivering three different signatures on three different deliveries.
Howevenf it is' also desirable, in some cases, to produce three signatures, each containing different advertising -inatter (possibly advertising different products from the} same company), mixed into a single issue in the same region. The folder shown is also capable of this method of delivery.
Broadly, the two'condit-ions are satisfied in this de sign by employing three deliveries, one of each different--regional division, or by employing two alternating deliveries, each delivering all three of the different signatures, so that they will be mixed in a single region.
"The'f'object of my invention is to provide a former folder "cylinder arrangement capable of delivering three diiferentsig'riatureson three different deliveries in which it is possible by rearrangement of elements carried by the respective'cylinder plus the silencing of one delivery to accomplish amixed signature operation with alternatdeliveries.- f
practical embodiment of my invention is shown in the 'accompanyingdra'wing in which FIG. lrepresents diagrammatically an end view of a folder constructed according to my invention in which signatures are-strccessively delivered to each of three deliveries, the pitch, line of the, gears for the drive being illustrated in relation to the respective cylinder;
' FIG. 2 represents an end viewof the embodiment shown .in;FI G 1 with the respective elements arranged on; their cylinders and with the lower pin transfer cylinder and the lower gripper delivery cylinder silenced so that the-signaturesare transferred alternately to the two deliveries; and
FIG. 3 represents a front view partly broken away on the work side of the frame, said view being partly broken away to show the means for silencing the lower pin transfer cylinder.
The traveling Web is denoted by 1 and it is passed through the usual forwarding rolls 2, 3 and 4, 5 between the right-hand and left-hand cutting and pin transfer cylinders which are denoted respectively by 6 and 7.
Located for operative engagement with the right-hand cylinder 6 is an upper gripper delivery cylinder 9 and similarly located with respect to the cutting and pin transfer cylinder 7 is an upper gripper delivery cylinder 8.
Also associated with the right-hand cutting and pin transfer cylinder 6 is a lower pin transfer cylinder 10 located for co-action with a lower gripper delivery cylinder 11.
A right-hand upper delivery 13 is located to receive "ice the products from the grippers on cylinder 9. A similar delivery '14 is located to receive the products from the grippers on cylinder 11 and a third delivery 12 is located to receive the products from the grippers on the cylinder 8.
The right-hand cutting and pin transfer cylinder 6 is provided with pins 15, 16, 17 and 18 which are operated in the manner well known in the art and, therefore, no further description of this operation is deemed necessary.
Also on said cylinder 6 are the knife boxes 19 and 20 provided with their knives.
On the left-hand cutting and pin transfer cylinder 7 are the pins 21 and 22, the knife boxes 23 and 24 plus the knives 25 and 26. It will be understood that the terms knives and knife boxes are used interchangea-bly.
On the left-hand upper delivery cylinder 8 are the grippers 27 and 28 and the boxes 29 and 30 which areadapted to receive grippers when so desired.
Associated with the transfer cylinder 7 is the usual feed pulley 31.
The upper right-hand delivery cylinder 9 is provided with grippers 32, 33 and gripper boxes 34, 3-5 which are adapted to receive grippers when so desired.
A feed pulley of the usual construction is located for co-action with cylinder 6 and is designated by 36.
The lower pin transfer cylinder 10 is provided with a pin 37 and also co-acts with the usual feed pulley 38.
The lower gripper delivery cylinder 11 is provided with grippers 39 and 40.
Referring to FIG. 2 the left-hand cutting and transfer cylinder 7 has added thereto the pin 41 and the right-hand cutting and transfer cylinder 6 is provided with the added knife box 42.
The left-hand upper gripper delivery cylinder 8 has an added gripper 43 and the right-hand gripper delivery cylinder 9 has an added gripper 44.
When cylinders 10 and 11 are in operation, hub 54 and gear 55 are bolted together by means of a driving plate 56, which is held by bolts 51 and '58. Thus cylinder 10 is driven through driving plate 56. I
To silence cylinders 10 and 11, bolts 51 are removed and placed through silencing bar 53 and the extension of plate 56. This now holds cylinders 10 and 11 in place. Thus bolts 51 occupy alternate positions depending upon whether or not the cylinders 10 and-11 are in operation or silenced.
With cylinders 10 and 11 silenced, hub 54 is free to rotate about gear 55.
The pitch lines of the gears for driving the respective cylinders are indicated in FIG. 1 and are designated as 45, 46, 47, 48, 49 and 50.
Referring to the operation of the arrangement shown in FIG. 1 when the former folder web is ledbetween cylinders 6 and 7 the first signature is cut by the knife 23 and carried by the rotation of cylinder 6 and the assistance of feed pulley 36 to the grippers 33 on cylinder 9 and subsequently delivered to the endless traveling carrier 13'.
The second signature is out by the knife 26, taken by the pins 16 on cylinder 6 and taken off by the pins 37 on cylinder 10 for subsequent passage assisted by the feed pulley 38 to the grippers 40 on cylinder 11. Delivery from this clyinder is to the endless carrier 14 operated in conjunction therewith.
The third signature is cut by the knife 20 on cylinder 6, taken by the pins 21 on cylinder 7 and assisted by the feed pulley 31 taken by the grippers 27 on cylinder 8 and delivered to the endless carrier 12.
The fourth signature is cut by the knife 25 and taken by the pins 17 for delivery to the grippers 32 on cylinder 9 for delivery to endless carrier 13.
The fifth signature is cut by the knife 24 on cylinder 7, taken by pins '18 on cylinder 6 transferred to pins 37 on cylinder 10 and thence to grippers 39 on cylinder 11 for delivery to the endless carrier 14.
The sixth signature is cut by knife 19 on cylinder 6, taken by pins 22 on cylinder 7 to grippers 28 on cylinder 8 and delivery to the endless carrier 12.
It will be understood that this sequence is repeated during subsequent operation.
It will be understood that the several elements on the several cylinders are not unique in construction being well known in the art, and it will be understood further that the pockets, A-M, inclusive, in the respective cylinders are normally adapted to receive pins, knives or grippers as the situation requires without the necessity for modification of same.
The apparatus shown in FIG. 1 is modified to produce the desired signatures as illustrated in FIG. 2 by the rearrangement and addition of the several elements as follows:
The lower pin trans-fer cylinder is silenced as outlined above. It is also desirable to remove the feed pulley 38. It is understood that the lower gripper delivery cylinder is also silenced.
With respect to the pocket A on cylinder 7 the knife box is removed and replaced by the pin apparatus 22. Pocket B is then fitted with the knife box 23 which has been removed from pocket A.
With respect to pocket C on cylinder 7 the knife box 24 is removed and a spare pin shaft and levers designated generally by 41 are placed therein.
With respect .to pocket E on the upper gripper delivery cylinder 8 the grippers 27 are removed and placed in pocket D. Pocket F on said cylinder 8 is furnished with a set of grippers 43.
With respect to pocket G on cylinder 6 the pin and associated equipment is removed and replaced with the knife box 19 from pocket H. The said knife box 19 is replaced with the apparatus 15 removed from pocket G.
The pin shaft andlevers denoted generally by 18 are removed from pocket I on cylinder 6 and replaced with knife box 42.
With respect to pocket L on the upper right-hand gripper delivery cylinder 9 the grippers 32 are removed and placed in pocket K. A spare set of grippers 44 are placed in pocket M of said last named cylinder.
The operation of the arrangement of FIG. 2 as thus equipped is as follows:
The signature cut at 19, is taken by pins 22 and carried to grippers 28 on cylinder 8 which grippers take said signature and deliver same to the endless carrier 12.
The second signature, cut at 26, is taken by pins 16 and carried to grippers 33 on cylinder 9 which grippers take said second signature and deliver same to end-less carrier 13.
. The cycle is repeated for succeeding signatures by succeeding knives and pins and grippers, Le, 20, 21, etc.
It will be understood that the lower pin transfer cylinder 10 and the lower gripper delivery cylinder 11 have previously been silenced as outlined above and that feed pulley 38 has been removed. Otherwise the drives for the respective cylinders and the means for actuating the several elements are as used for the same cylinders illustrated in FIG. 1.
Since it is evident that changes may be made in the form, constructed and arrangement of the several parts without departing from the spirit and scope of my invention, I do not intend to be limited to the specific embodiment herein shown and described except as set forth in the appended claims.
What I claim is:
1. In a former folder cylinder arrangement a pair of rotary cylinders of the same diameter having interchangeable coacting devices for cutting a web or assoclated webs into signatures and transferring sai-d signatures, means for advancing a web or webs to said devices at press speed, a plurality of identical pockets in each of said rotary cylinders for carrying said interchangeable devices, one delivery cylinder directly associated with each rotary cylinder of said pair, four identical po kets in each said delivery cylinder, interchangeable gripper mechanisms in at least two of said pockets on each said delivery cylinder, a third delivery cylinder remote from,
one of said pair of rotary cylinders, a transfer cylinder operatively connecting said third delivery cylinder with said one of said pair of rotary cylinders and an endless carrier associated with each of said delivery cylinders whereby three signatures of different content may be delivered each to its own delivery. Y
