United States Patent e 2,908,294 WEB ASSOCIATEii FOLDER George Roger's Brbdi'e ,-Nai'lirth, l a. assign'or to Fredk H. Levey Comp y, lnc'g Ne'wYoik, N.Y., a corporation of New York Application May 15, 1957, Serial No. 659,412 4 Claims. ((31. 2'70-=41) This invention relatesfto improvements in folding mechanisms used in conjunction with web-fed printing presses. It relates more particularly to mechanisms especially adapted to use in conjunction with conventional cutting and folding mechanisms wherebythe web is first slit longitudinally into ribbons and the respective ribbons automatically aligned and brought together and thereafter passed together over a former for effecting a longitudinal fold in the assembled ribbons, usuallyalong their centerline.

It isfrequently desirable to produce whatis known as a gate fold in one of the ribbons before they are assembled either for the purpose of increasing the size of a regular page in the printed publication by folding inwardly the unbound edge of the page, in whichcase the gate fold is less than half the widthof the ribbon, or for producing an additional page wherethe gate fold is equal to half the width of the ribbon. The latter has been found especially desirable Where the web is ofsuch width, with respect to the desired page size of the finished publication, that it is impractical to divide the web into ribbons of equal width. 7 p 7 The present invention provides novel and'highly useful mechanisms whereby a gate fold of any desired width'may be made in any one of the ribbons passing from the cutter roller to the conventional former.

This improved mechanism in generaloomprises a gate fold former and associated rolls mounted one frame adjustably supported, advantageously by the side frames of the cutting and main folding mechanism, and adapted to be readily moved transversely with respect to the path of the web entering the mainfolder so that any one of the several ribbons'may be passed through the gate folder and thereby folded at any desiredposition with respect to the width of that particular ribbon. 7

According to the preferred embodiment of theinvention, the gate folding mechanism is adapted to be moved transversely of the web so as to receive anyone of the several ribbons as stated above. However, the invention contemplates mechanism wherein the movement of the gate folder is more restricted in that his adapted to be moved transversely with respect to a single ribbon.

The invention will be further described and illustrated with reference to the accompanying drawings whichrepresent conventionally, and somewhat diagrammatically, a presently preferred embodiment of the invention and of which:

Fig. l is a front view of my gate "folder showing its relation to conventional aligning and folding mechanism, and partly broken away to show pertinent'inner portions thereof, and

Fig. 2 is a side view along the line-2-2 of Fig. 1.

The incoming web l passe's from the press through'oonventional slitting means indicated at 2, comprising a slotted roll and cooperating slitting blades, "whereby the web is cut into longitudinal ribbons, for instance three ribbons indicated by the reference numerals 3, 4 and 5. Ribbons 3 and 4 are of equal width and ribbon Sis somerolls "1'3.

Patented Oct. 13, 1959 2 what wider. These ribbons-pass from roll 2 around roll 6 and thence ribbons 3 and -4 pass over rolls 7 and 8, respectively, and then overadjustable angle bars 9 and 10, respectively, in acco rdance with conventional practice, whereby the ribbons 3 and 4 are aligned and pass from the angle bars over rolls 9a and lila and are then passed together over roll 11. From roll 1-1-tl1e assembled ribbons passover a conventional former-indicated at 12 for 'efiecting the longitudinal folding of the assembled ribbons. The folded ribbons then pass between creasing Ribbon '5, being of greater width than ribbons 3 and 4,

While the invention will be illustrated as eifecting a gate fold in ribbonS, theposition of my gate folder is adjustable, as hereinafter described, so as to receive and fold any one of the ribbons andtoposition the gate fold therein at any desired distance from either of the side edges of the selected ribbon; 5

My improved gate folder is adapted to be used in conjunction with conventional folders and comprises side frames 16 adjustably supported by a base frame 17 which in turn is adjustably supported, advantageously by the main folder side frames .1 8 and keyed thereto by tracks 19, as more clearly-appears in Fig. 2, and adapted to be moved along the tracks by rotation of elongated screws 20 are threaded through the base frame 17. These screws 20 are supported at each end and secured against longitudinal movement by'brackets represented at 21, said brackets being-secured to frame 18 of the main folder. The tracks '19 and screws 20 are of-sufficient length toenable the ate-rename be moved transversely of the web to coincide with th elpath of any one of the ribbons by turning the screws-2'0 by any suitable means, not shown, for instance ahantl crank. It is desirable that the rotanon of the screws 2 0be coordinated. Means for accomtion and thenp'asses between the former rolls 2521, adjustably supported hereinafter described, and then between creasing rolls 2.5 rotatably supponted between the base frames 17,

From the creasing rolls 25, the gate folded ribbon is passed around guide rolls 2 6 and 27 and take-up rolls 28 and then passes over roll 111 together with ribbons 3 and 4.

It is usually required that at least one edge of gate folded ribbon '5 be aligned with the corresponding edges of ribbons and 4'before being passed to roll 11. For accomplishing this purpose, I provide means for moving the former 24in a direction parallel to the bite between the creasing rolls 25 so 'ast'o shift the folded ribbon longitfudinally ofthos'e -rollswl:|ic'h,in turn, will shift the position of folded ribbon '5 h'ansyersely of ribbons 3 and 4 passing over roll 11.

This is accomplished'in thespecific apparatus shown by mounting thesidefraines lfi so-that their position may be adjusted with respect to base-17 along a plane perpendicularto "the plane of adjustment of the base 17 previously described. e

As shown in the drawings, the side frames :16 "are ke'yedto 'slidesdfl secured to base frame 17 and extending .perpendicularto slides 1'9 previously described. Adjust'm'ent screws 1 31-are threadedinto side projections of frames ,16 and are supported at their outer ends, and

secured against longitudinal movement, by brackets 32 also supported by brackets 32 and is provided with a hand crank 36 by which screws 31 may be rotated to cause frames 16 to move in the desired direction along tracks 30 thus effecting the aligning of folded ribbon with ribbons 3 and 4.

The creasing rolls 25 are geared together by cooperating gears 37 and are driven through beveled gear 38,

secured to roll shaft 39, and cooperating beveled \gear 40 keyed to be driven by spline shaft 41 and adapted to slide along said shaft as the position of the gate folder is adjusted transversely of the web. Shaft 41 is rotatably supported at each end and is adapted to be driven by conventional means.

Beveled gear 40 is supported and held in mesh with gear 38 by means of bracket 42 secured to the base 17 and adapted to move therewith.

The roll 23 may be driven by any suitable means. Advantageously it is driven through means supported by base 17 so that the driving connection would not be disrupted by the moving of the gate folder transversely of the web. However, where the driving means is attached to base 17, provision should be made for the adjustment of side frames 16 with respect to base 17. Usually the latter adjustment will involve a movement not exceeding one inch in either direction from the center position. In such case, a drive connection through one or more universal joints, as shown in the drawings, may be used satisfactorily.

In the apparatus shown, I provide spline shaft 43 extending the length of the folder and supported at each end by brackets 44 secured to side frames 18 of the main folder and driven by any suitable means, not shown.

Beveled gear 45 is keyed to, and adapted to slide along, shaft 43 and is rotatably held in position to mesh with cooperating beveled gear 46 by means of bracket 47 secured to the gate folder base 17. Gear 46 is secured to the lower end of shaft 48 and is rotatably supported by brackets 47' and 49 secured to the base 17. Shaft 48 is connected to shaft 50 through universal joint 51.

The other end of shaft 50 is connected through universal joint 52 to shaft 53 rotatably supported by bracket 54 secured to side frame 16 and connected with shaft 55 to roller 23 through cooperating

beveled gears

56 and 57.

The former rolls 25a are rotatably supported at each end by separate bearing brackets 58 adjustably mounted on cross braces 59 in any suitable manner, as by means of bolts. The braces 59 are secured to the gate folder side frames 16, as by welding or riveting, as more clearly shown in Fig. 1 of the drawings.

In the operation illustrated, the ribbon 5 in which the gate fold has been made is the lowermost ribbon passing over roll 11. However, by changing the path of the ribbon leaving roll 26, for instance by passing it to rolls 28a or rolls 27a and 28b, as shown in dotted lines in Fig. 1, ribbon 5 may be caused to pass to roll 11 either above or between ribbons 3 and 4. It will be understood that the invention is not restricted as to the number of ribbons being passed to roll 11 in addition to that being passed through my gate folder.

It will be understood that the invention is not restricted to the particular embodiment thereof, herein specifically described by way of illustration, but contemplates the use of equivalent cooperating means or parts within the scope of the appended claims.
