March 1966 c. H. ROSENBERG METHOD AND APPARATUS FOR MAKING BOOKS Filed Feb. 2'7, 1963 INVENTOR. CHARLES H.ROSENBERG ATT RNEYS United States Patent 3,237,934 METHOD AND APPARATUS FUR MAKING BOOKS Charles H. Rosenberg, Box 2275, Tallahassee, Fla. Filed Feb. 27, 1963, Ser. No. 261,274 22 Claims. ((1 27l)53) This invention relates to the art of making books, and more particularly to making books or booklets consisting of single sewn signatures.
An object of the present invention is to provide a novel method of and apparatus for making books, such as booklets of the type adapted for use as trading stamp books.
Another object of the invention is to provide a novel method of fabricating books automatically from a plurality of webs of sheet material, such as paper.
A further object is to provide a method of making single signature books and the like with increased speed at reduced cost.
Still another object of the invention is the provision of a novel, completely automatic and continuous process for converting rolls of web material into sewn signatures or books.
The above and further objects and novel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawing. It is to be expressly understood, however, that the drawing is for the purpose of illustration only and is not intended to define the limits of the invention, reference for this purpose being had primarily to the appended claims.
In the drawing, FIG. 1 is a schematic side elevation view illustrating one form of apparatus for carrying out the novel automatic method contemplated by the invention.
The novel method of the invention may be carried out by the use of known aparatuses novelly arranged and power operated in unison to cooperate in the manner schematically illustrated, by way of example, in the accompanying drawing. Said apparatus comprises a multiple roll or multiple web collator ill which mounts a plurality of rolls 11.2 of paper or other sheet material, collates the webs fed from the rolls in superposed or stacked relation, and feeds the collated webs continuously to a stitcher la. The single webs 16 forming the rolls 12 may be desirably printed on one or both sides in a web press (not shown) which is preferably provided with Teletype punching means for cutting or punching spaced perforations adjacent one or both edges of the webs to permit subsequent feeding and collating of a plurality of the webs in accurate register with each other. Each web is rewound on a roll as it issues from the press for subsequent mounting on the collator 10. The rolls may be mounted on a series of parallel unwind shafts 18, as shown, or the same may be located at one side of the collator on a common power driven unwind shaft and fed to the collating conveyor over right angle turning bars and suitable feed rolls in a manner known to the art.
The web from each roll 22 may be passed over one or more suitable feed rollers and laid down on an endless band conveyor 2% forming part of collator it The web 16 furthest to the right, as viewed in the drawing, is laid down in direct engagement with the conveyor band, and the webs to the left thereof are successively stacked thereon to form in effect a multi-ply web 22. The collating band conveyor 2t) may comprise a single endless band or one band which is fixed against transverse adjustment and a second hand which is transversely adjustable to make the conveyor capable of accomodating webs of different widths. Outwardly projecting pins 24 are provided 'ice at the edges of the conveyor band or hands, the same being suitably spaced to cooperate with the above-mentioned Teletype punched perforations adjacent the edges of the webs, and thus maintain the latter in perfect register with each other and the collating apparatus.
The uppermost web 16 of the plurality stacked on the collating conveyor band may be of different stock than the other webs to form a suitable cover for the booklets being formed. If desired, a suitable cylinder type imprinting unit (not shown) of known construction may be provided at the delivery end of the collator to print desired subject matter on successive sections of the cover web.
The stacked or multi-ply web 22 is delivered directly and continuously from the collating conveyor 2t) or from an interposed imprinting unit into gripper feed rolls 26, 27 at the entrance to the gang stitcher 14, which may be of any suitable known construction, such as a Bostitch or similar gang stapler. The multi-ply web 22 is fed by rollers 26, 27 onto a table or support 28 beneath a desired number of transversely arranged stitcher heads 3tl and thence, to the stitcher delivery feed rolls 32, 33. The rollers 26 and 32 are provided with radially projecting pins which have the same spacing as pins 24 on the collating conveyor and engage the perforations in the stacked webs to maintain mutual registry thereof with each other and the stitcher. Stitcher 14- operates periodically to apply a transverse series of staples or other suitable stitching across the width of the multi-ply web 22 at pre-selected intervals along the web at the centers of the longitudinal sections of the web which are to be subsequently severed and .folded into booklet form. The stitcher drive, which is not shown in detail but may be of known construction, is preferably so designed that the section of the web 22 between feed rollers 26 and 32 is momentarily stopped during each stitching operation and thereafter moved at a speed slightly in excess of the speed of the collating conveyor 20 to take up slack in the web ahead of the stitcher and create a suitable slack at the delivery end of the stitcher.
The stitched or sewn web 22 is now fed directly from stitcher delivery rolls 32, 33 to a unit comprising an endless band conveyor 34, edge trimming cutters 35, 37, gripper feed rolls or pull unit 38, 39, and a cut off-folding mechanism comprising three cylinders 40, 41, and 42. Booklets delivered by the latter mechanism may be laid down on an endless conveyor 44 in overlapped relation to be easily gathered therefrom by either manual or known mechanical means. If desired, this conveyor may be momentarily speeded up periodically in response to a booklet counter to separate the overlapped booklets into groups comprising a pre-determined number thereof.
Conveyor 34 may be, and preferably is, basically similar to collator conveyor 20 with outwardly projecting pins 45 at the edges thereof for registry and cooperation with the edge perforations in the web 22. Conveyor 34 is driven continuously at a speed which will avoid excess slack in the stitched web 22 between it and stitcher 14, and which will maintain accurate timing and registry of the web for the subsequent trimming and cutting operations. The pin band of conveyor 34 moves and maintains web 22 in a straight path and times its longitudinal movement for registry with the transverse cutters as on drum or cylinder 40, to thereby insure square cuts across the web on pre-determined lines half-way between successive rows of stitches.
After leaving conveyor 34, the web passes through the gripper pull unit comprising driven feed roller 38 and yieldable pressure roller 39. This feed or pull unit preferably exerts a slight pull on the web, resisted by conveyor 34, to maintain the web under slight tension. At a point between conveyor 34 and gripper pull unit 38, 39, a suitable known means may be provided for trimming the perforated edge portions off the moving web. In the form of apparatus shown, the edge trimming is accomplished by pairs of overlapping cutting discs 36, 37, but any suitable known type of trimming mechanism may be used.
The web 22 when thus trimmed may have the width equal to the desired length (top to bottom) of the booklets being produced, or if desired, the width of the web may be twice or several times the length of the shortest booklets being produced. In the latter event, the moving web may be longitudinally slit to permit simultaneously forming two or more booklets from each sewn section of the web and thereby greatly increase the production capability of the apparatus. The desired longitudinal slitting of the web into two or more widths and hence, two or more side-by-side webs, may be accomplished by overlapping disc cutters similar to and located between the pairs of edge trimming cutters 36, 37. A separate gripper pull unit is preferably provided for each of the resulting narrower webs. The grippers at opposite sides of the longitudinal center may in this case be slightly out of line so that the outermost webs gripped thereby will be slightly transversely separated from each other or from a center web which need not be deflected from its straight path.
The web or each of the webs moving side-by-side as the case may be is fed by a gripper feed or pull unit 38, 39 into the bite of rotating drums or cylinders 40 and 41, having circumferences which are multiples of the distance between the lines or rows of stitching across the web. In the illustrated embodiment, the interval between stitches is equal to one-half the circumference of each of said cylinders which are driven in the direction of the arrows. Drum or cylinder 40 is provided in a known manner with two diametrically disposed radially reciprocable pinch cut-off blades 46 which engage the upper surfaces of the web as it enters the bite of drums 40 and 41. These blades act against diametrically disposed anvils 48 on cylinder 41 to sever the moving web transversely from edge to edge and thus cut therefrom a longitudinal section to be folded into book form.
The conveyor 34 and the cut-off cylinders 40 and 41 are driven in timed relation so that the cutting blades 46 will transversely sever the web along lines one-half the distance between successive rows of stitches across the web. Adjacent each of the anvils 48 on cylinder 41 there is mounted a pivoted gripper 50 which is actuated in timed relation and in response to rotation of the cylinder to grip the leading edge of the web and hold it against anvil 48. Thus, as the web is continuously fed between cut-off cylinders 40 and 41, the leading portion or section thereof is held against and wrapped around one-half of the periphery of cylinder 41, while another cutting blade 46 moves into position to sever the web between the next rows of stitches or staples. At about the same time the gripper 50, then having reached the bottom of cylinder 41, releases the leading edge of the severed section of the web, and one of two oppositely disposed, radially reciprocable tuker blades 52 on cylinder 41 is actuated outwardly to press the severed section of the web outwardly along a central fold line containing the row of stitches and into the clamping jaws of grippers 54 carried by fold cylinder 42. There are two diametrically disposed pairs of gripper jaws 54 to cooperate with tucker blades 52. Upon further clockwise rotation of cylinder 42, as viewed in the drawing, while the severed end section of the web is gripped by jaws 54, said section is folded and released to fall onto conveyor 44 as a completed booklet. If desired, suitable stationary means may be provided for stripping each booklet from cylinder 42 as it is released by gripper jaws 54. The gripper 50 at the top of cylinder 41 is actuated to grip the leading edge of web 22 immediately after the cutting action of blade 46 and the folding cycle is repeated. Thus, if the original multi-ply web is slit into several narrower webs in the manner described, a plurality of booklets are simultaneously folded and dropped onto conveyor 44.
The entire apparatus, from the web collator 10 to delivery conveyor 44, for automatically performing the novel method of the invention may be driven by a suitable common source of power, such as an electric motor (not shown) through a series of gear boxes 56 connected to the source and to each other by a sectional line shaft 58. Suitable known types of driving connections are made from the several gear boxes to the collatcr 10, the stitcher 14, conveyor 34, the trimming and slitting cutters, gripper pull units 38, 39, the cut-off-folding cylinders and the delivery conveyor. If desired, provision may be made for varying the speed of operation of the various units of the apparatus in order to adapt the equipment for making books of different widths (folded edge to open edge). For this same purpose, the web cut-offfolder unit comprising cylinders 40, 41 and 42 may be removably mounted on the main frame to permit the mounting and use of other similar units having a larger number of cutters, grippers and tucker blades differently spaced on the cylinders.
There is thus provided a novel method of automatically fabricating sewn booklets at high speed from a plurality of webs of sheet material which may be pre-printed on one or both sides. Said method, which comprises the continuous feeding of the webs, collated into superposed registry from a plurality of rolls, has the advantages of large volume production at low cost with a minimum of equipment requiring a minimum of floor space and a minimum of manual labor and supervision.
Although only a single embodiment of apparatus, with a limited number of modifications, has been illustrated and described for carrying out the method of the invention, it is to be expressly understood that other comparable apparatuses, differing in specific detail, may be used.
