WEB-PRINTING MACHINE.

Application filed April 21, 1911.

To all whom it may concern.

Be itknown that I. CARL A. KnLLooo, a citizen of the United States, and a resident of Battle Creek, Calhoun county, Michigan, have invented certain Improvements in \Veb-Printing Machines, of which the following is a specification. v

This invention relates to certain improvements in web printing machines, and more particularly in that class of such machines which are adapted for use in work and turn printing, and wherein the web after being printed upon one surface from a set of forms, is reversed or turned about and again printed upon its opposite surface from the same set of forms in such a manner that duplicate page impressions are produced upon the respective opposite surfaces of the web. and the object of the invention is to provide a machine of this general character of a simple and comparatively inexpensive nature having a novel and improved construction and arrangement of web guiding, folding and cutting mechanism, operable to manipulate the perfected web in such a manner that the duplicate page impressions, despite their reverse arrangement in the web. are associated and delivered from the machine in proper sequence and in a substantially continuous manner.

The invention consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved web printing machine, whereby certain important advantages are attained, and the machine is rendered simpler, less expensive, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my improvements may be the better understood. I will now proceed to describe the invention with reference to the accompanying drawings, wherein Figure 1 is a fragmentary perspective and somewhat diagraphicillustration of a rotary printing machine embodying my improvements applied for use in the production of a sixteen page product; Fig. 2 is a detached detail view showing certain features of the web guiding means to be hereinafter described; Fig.3 is an elevation illustrating the arrangement of the cutting and folding mechanism for cutting and folding the product in the machine shown in Fig. 1;

Serial No. 622,442.

Fig. 7 is a view illustrating the lay-out of the plates for producing an eight page product upon the machine illustrated in Fig. 1; Fig. 8 is a view somewhat similar to Fig. 1, but illustrating a different formation of rotary printing machine especially well adapted for use in printing a six page prod-,

uct; Fig. 9 is a diagraphic representation of the positioning of the web during the production of the six page product; Fig. 10 is a view illustrating the lay-out of the plates for producing a six page product upon the machine illustrated in Fig. 8; Fig. 11 is another diagraphic perspective view somewhat similar to Fig. 8, showing a slightly different formation of rotary printing machine comprised in my present invention and applied for use in the production of a six page product; Fig. 12 is a view illustrating the lay-out of the plates for the production of the six page product upon the machine shown in Fig. 11; Fig. 13 is a fragmentary plan view illustrating the arrangement of the formers of the folding and cutting mechanism in the'machine shown in Fig. 11; and Fig. 14 is another view somewhat similar to Fig. 11, but showing the embodiment of my improvements in a machine for printing from flat forms, and the adaptation thereof for the production of a six page product.

I will first describe my invention with reference to Figs. 1 to 6, wherein I have shown my improvements embodied in a sixteen page work and turn printing machine, premisin however, that the improved printing machine is not limited to the production ofa sixteen page product but may be adapted with good results to the printing of products of other page numbers by proper variations within the scope of the present invention. As shown in these views, the improved printing machine is of the rotary type and is provided with two sets of printing devices 1 and 2. each including a central plate cylinder3 having two series of plates 4 and'T), impression cylinders 6 and 7 at opposite sides of the plate cylinder 3, and web guiding and turning means including a.

plate cylinder3, a second guide roller 9 as g which receives -the web after the same has been printed upon the impression cylinder 6 and directs said web to a turning bar 10 whence such web is deflected laterally to the side of the machine around a guide roller 11 and is again directed toward the center of the machine to and around a second turning bar 12 at right angles to the turning bar 10 and operating to direct said web to a third guide roller 14: whence the web is directed downward to theimpression surface of the impression cylinder 7 whereuponits opposite unprinted surface is presented to the plates of the plate cylinder 3 so that the web may be perfected after having been turned by the turning devices above referred to. 15, 15 represent guide rollers which receive the web after the same has been printed upon the impression cylinders 7 and direct the same upward to an auxiliary guide roller 16 whereon the web from both the printing devices 1 and 2 is received in superposition and whereat a slitter 17 operates to sever the superposed runs of web into two parallel streams 18 and 19 which are directed forwardly therefrom and pass over a delivery roller 20 to the V-shaped formers 21 of cutting and folding mechanisms 22 and 23 which are erected closely adjacent side by side in position to receive said streams.

In the production of a sixteen page product, the plate cylinders of the respective printing devices 1 and 2 being each four plates long and two plates in circumference as herein shown, may be provided with a single series of plates laid as indicated in the diagraphic view, Fig. 6, wherein 3 represents the lay of the plates upon the cylinder 3 of the printing device 1 while 3? represents the lay of the plates upon the plate cylinder of the printing device 2. The set of series of plates 3 and 3 thus provided at each of the respective printing devices 1 and 2 is so laid as to be divided into two groups 3 and 3 usually in similar positions as to their folios, one such group of plates as 3 being arranged to print upon'one lateral side or half of the web while the companion group as 3, is adapted to print upon the opposite lateral side or half of the web at the same impression, and in laying the plates at each printing device, in these respective groups, the page plates included in one group, as page plates 16, 9, 8, and 1 in group 3 at 3 in Fig. 6 are complementary to the page plates of the companion roup as 15, 10, 7, and 2 in group 3 It will thus be seen that the web at each production of the product at the cutting and folding mechanism, as will more fully appear hereinafter, the similar arrangement of the folios in the respective groups at each set or series'of plates, assuring the registry of each page impression at one surface of the web with its related or hacking page impression at the opposite surface of the web by reason of the turning of such web be: tween impressions. WVith the above described grouping and arrangement of the page plates in the structure shown in Figs.

1 1 to 6, the web 24 fed through the printing device 1 will receive duplicate page impressions 1, 7, 717 1O, in reverse arrangement upon its opposite surfaces while the. web 25 fed through the printing device 2 will similarly receive duplicate page impressions 4, 5, 3, 6, 13, 12, 11, 14 also in reverse arrangement upon its opposite surfaces.

Each web 21 and 25 to be printed upon the four page wide cylinders 3 of the printing devices 1 and 2 is four pages wide also, as herein shown, but it is obvious that two runs of web two pages in width may be fed through each printing device side by side with precisely'similar results, in which event the slitter 17 will not be required, and since the present invention is not limited with respect to the exact width of the web to be printed, I desire it to be understood that where I have employed the expression web throughout this specification and the appended claims, the same is used in its collective sense. The lay of the plates as indicated in Fig. 6 is such that the page impressions produced upon the corresponding lateral halves or sides of each web 24 and 25 in the work and turn operation of the respective printing devices 1 and 2 will be complementary to each other so that when web 21 is superposed upon web 25 at the auxiliary guide rollers 16 and the superposed runs are divided by means of the slitter 17, the corresponding lateral halves or sides of the superposed runs of web entering into the stream 18 will be comprised of pages in proper order and sequence with columns running lengthwise of the web and with their title pages T outermost, in position to permit their appropriate delivery to the former 21 of the corresponding cutting and folding mechanism'22. By reason of the work and pages 3 and 7 which should be at the upper or outer surface of the lowermost web 25 where the stream 19 passes over the guide roll l6will be positioned at the lower or inner surface of said web, so that the pages will be thrown into such improper order and position as would prevent the delivery of the finished product from a cutting and folding mechanism such as is shown at 23 in the drawings. In connection with the parts constructed and arranged as abovedescribed for use in the production of a sixteen page product, I provide two sets of turning devices interposed in the path of the stream 19 between the auxiliary guide roll 16 and the delivery roll 20 at the V-shaped former 21 of the folding and cutting mechanism 23, one such set of turning'devices including a turning bar 26 co-acting with the outermost web 24 in the stream 19 to deflect the same laterally as shown at 24 to a guide roller 27 at the side of the machine whence said web is directed again into the machine as indicated at 24 to a turning bar 28 at right angles to the turning bar 26 and adapted for operation to direct said web to the V-shaped former 21 of the folding and cutting mechanism 23 in a position reversed to that in which said 'web traverses the guide roll 16 so that the title page T'- may be presented outermost during itstravelover the former 21 and in the product delivered from the cutting and folding mechanism 23. The other set of turning devices interposed between the guide roll 16 and the delivery roll 20 includes a turning bar 26 inclined similarly to the turning bar 26 but cooperating with thelower web 25 comprised in the stream 19 to deflect said web outwardly as indicated at 25 to and around a guide roller 27 at the side of the machine whence said web is again directed into the machine as indicated at 25 to and around a turning bar 28 shown in dotted lines in Fig. 1 and inclined similarly to the turning bar 28 so as to operate to direct said web to the V- shaped former 21 of the cutting and folding device 23 with its pages 3 and 7 outermost in position to pass through the cutting and folding mechanism in proper relation to the pages of the outermost web 24.

In Figs. 1 and 2 I have illustrated the turning devices for the web 24 in stream 19 arranged above the path of the web over the guide roll 16 and theturning devices for the web 25 in said stream below the path of the web over said guide roll 16 but this arrangement is obviously in no way essential to my invention nor is it essential that the cylinders be plated in the exact manner herein set forth for the production of a sixteen pa'ge product, nor is it essential that the turning devices for the web runs 24 and 25 prior to their delivery to the cutting and folding mechanisms be arranged to cooperate with the stream 19 since similar results may be accomplished upon proper laying of the plates by arranging the turning devices to cooperate with one or both the runs of web in the stream 18. The improved printing machine constructed and arranged to operate as above described permits the pro- .duction of a sixteen page product from a single series of plates without requiring duplication of the plates but when this result is effected in the manner set forth, it is requisite to employ collecting means at the cutting and folding devices for which purpose the cutting cylinders 29 of the respective cutting and folding devices 22 and 23 are provided with collecting pins 30 so that alternate sheets cut from the web at each stream 18 and 19 may be collected upon the cutting cylinders and by proper manipulation of said pins 30 and of thepins 31 of the carrying cylinders 32 may be transferred and associated with succeeding sheets prior to the half page folding of the product at the folding rolls 33. Where desired also duplicate plates may be providedupon the cylinders 3 of the respective printing devices l and 2 in lieu of the single plates provided as above set forth. Fig. 7 shows the lay of the duplicate plates upon the plate cylinders where an eight page product is desired. Where the plates are duplicated it is obvious that the capacity of the machine will be doubled since collecting will be dispensed with and each of the cutting and folding mechanisms 22 and 23 will be operated at full capacity.

In Fig. 8 I have shown a construction of printing machine embodying my invention wherein plate cylinders 3 each but a single plate in circumference are provided, adapted to receive tubular plates in a well known way. This machine ermits the production of a product from a single set of plates without collection, thereby affording page for plate capacity, and permits the production of a six page product without such duplication of plates. In the production of a six page product upon the machine constructed as shown in said figure, presuming the cylinders at the printing device 1 to be provided with plates laid as shown at 3 in Fig. 10 and the plate cylinder of the printing device 2 to be provided with plates as shown .at 3 in said figure, the web 34 passed through the printing device 1 will be printed 389 upon one surface with pages 6, 1, 2,

5, in close succession and upon being turned will be printed with the same pages in reverse arrangement also in close succession while the narrow or two pages wide web 35 passed through the printing device 2 will be printed upon one surface with pages 4 and 3 and upon being turned will be printed upon its opposite surface with the same pages in reverse arrangement. The plates 3 for printing pages 4 and 3 upon the web 35 are laid upon the cylinder 3 of the printing device 2 centrally of the length of said cylinder, and said web 35 is also passed centrally through the web guidingmeans at said printing device 2, so as to be presented in position to be perfected upon said plates 3 during the work and turn operation, after which said web is passed centrally over the auxiliary guide roll 16 so that the central marginal spaces between the longitudinal series of page impressions upon the web is presented to the slitter 17 in order that the latter may operate, during the severing of the uppermost web 34, also to sever the lowermost two page wide web 35 into two lateral sides or halves each of but one page in width. The one-page wide web runs 35 and 35 thus produced by the operation of the slitter 17, are fed forward over the delivery roll 20 to the formers 21 of the cutting and folding mechanisms insuch a.

manner that the single page web 35 is associated with the superposed twopage wide web 34 in the stream 18 passing directly over the former of the cutting and folding mechanism 22, page 3 of said single page web being uppermost so as to be positioned beneath page 2 of the superposed two-page web 34, whose title page T is outermost, while the one-page web 35 is directed forwardly beneath the opposite two-page web 34, whose title page T is lowermost, and has its, page 4 surface uppermost so that as the said two page web 34 is turned or reversed by means of the turning bars 26 and 28 above referred to, said one page Web 35 will be ,associated at the delivery roll 20 with said turned two page web 34, with the page 4 surface of said one page web beneath the page 5 surface of said two page web, in order that the web runs thus associated in the stream 19 may pass down over the former 21 of the cutting and folding mechanism 23 in proper relation and sequence to afford successive delivery of the six page product from both the cutting and folding mechanism 22 and 23. In this form of the improved printing machine the central positioning of the two pages wide web 35 with relation to the four pages wide web 34 permits of conveniently imparting to said web 35 such slight additional width as may be necessary or desirable for pasting the inserted sheets at the central fold .of the two page wide web produced by the former, so that the sheets may be secured together in the six page product. To attain this result the two page wide web 35 may be of such Width as to permit its outer edge portions 36, 36 after having been supplied with paste from a pasting device 37 to be folded over by means of the formers 21 of the cutting and folding mechanisms 22 and 23 in the manner indicated in Fig. 9 of the drawings.

The machine constructed as shown in Fig. 8 having plate cylinders each one plate in circumference for use in connection with tubular plates may be employed for printing an eight page product with equal facility and has the advantage over the construction shown in Fig. 1 of dispensing with collection and thereby permitting operation of the machine at the full capacity of the cutting and folding mechanisms. By increasing the number of plate cylinders or varying their length it is also obvious that further differences in the product may be attained.

In Figs. 11 and 13 I have shown another embodiment of my improvements wherein one set of the turning devices between the rolls 16 and. 20 is dispensed with. In these views I have shown the. machine adapted for employment for the production of a six page product from a four pages wide web 34 and a two pages web 35, the latter being superposed upon the four pages wide web at the slitter 17 in such a manner that the single page web runs produced therefrom are both directed upon the upper surfaces of the two page web runs produced from the web 34. The V-shaped formers for the two cutting and folding mechanisms 22 and 23 are arranged at opposite inclinations with respect to the direction of travel of the web thereover, so as to be adapted to receive correctly the reversely positioned title pages T and T in the two pages wide web runs and the reversely inclined turning bars 26 and 28 are so arranged as to deflect .one of the single page web runs as 35 produced by the slitter 17 laterally across the upper surface of the corresponding two pages wide web 34 and downwardly at the side of the machine and thence backward beneath said two pages wide web 34 into position to be associated therewith in proper page relation. The machine illustrated in these views is provided with plate cylinders each four pages in length and two pages in circumference so as to be adapted for employment for the production of products up to sixteen pages. The machine may thus be used for printing page for plate or may be equipped with duplicate plates.

Where a six page product is required theplatesmay be duplicated and laid as shownin Fig. 12 of the drawings.

' In Fig. 14 I have illustrated another em- 5 bodiment of my improvements especially adapted for use in printing from flat forms wherein the printing devices 1 and 2 are arranged end on with respect to one another ing devices 1 and 2 In this form of the' Invention it is obvious that either the flat beds 1 or their cooperating cylinders 2", 2", will reciprocate as in the structure shown in my co-pending patent application, Serial No. 613,404. Two sets of turning devices are provided between the rolls 16, 16, one comprising oppositely inclined turning bars 38 and 39 adapted to direct the two pages wide web runs 40 produced by the slitter from the four pages wide webs 41 perfected by the printing device 1 toward opposite sides of the machine whereat they are received by delivery rolls 42 which direct them downward over the reversely inclined V-shaped formers of folding and cutting mechanisms 43 and 44 positioned at opposite sides of themachine. The other set of turning devices is designed to cooperate witha two pages wide web perfected at the printing device 2 and includes oppositely inclined turning bars 45 and 46 adapted,

- when the corresponding slitter is centrally positioned with respect to its guide roll 16, to direct one half of the web from the printing device 2 above the corresponding half of the web from the printing device 1- in position to be associated'therewith at the corresponding cutting and folding mechanism 44, and the other half of the web from the printing device 2 below the corresponding half of the web from the printing device 1 in proper position to be associated-therewith at the other cuttlng and folding mechanism 43. The turning means for the web from printing device 2 also includes an auxiliary turning bar 47 which is adapted, when the slitter is moved from its central position, as indicated in the drawing, to receive one half 48 of a two page web 49 perfected at the printing device 2 and to direct the same beneath one of the halves of the four page web perfected at the printing device 1. in position to be associated therewith at the corresponding cutting and folding mechanism 43, the other half 50 of said two page web passing around an auxiliarv turning bar 51 and above the opposite half of the four page web from the printing device 1 so as to be assoclated therewith at the other cutting and folding mechanism 44.

From the above description It will be seen that the improved printing machine constructed according to my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the doubly increased capacity afforded by the work and turn printing and of the fact that the web guiding means and cutting and folding mechanisms are so arranged as to permit the duplicate impressions to be associated in correct page relation to be delivered in sequence without requiring extensive modification of the cutting and folding-mechanisms or material impairment of the speed at which the same are operated excepting such as may be due to collecting of the sheets, and it will also be obvious from the above description that the machine is susceptible of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the improved machine' as herein set forth, in carrying out my invention in practice.
