Abstract: 18,656. Newton, H. E., [Hoe, R.]. Aug. 25. Rotary machines; associating, cutting, and delivery apparatus; folding paper.- Relates to rotary machines for printing a plurality of webs partly in colours and partly in black, or all in black, and producing a large variety of folded products therefrom. Fig. 1 shows a machine having six printing- mechanisms, three at each end of the machine and preferably one above the other, as shown. More or less than three mechanisms at each end of the press may be used. The mechanisms are arranged in line longitudinally of the press, and each mechanism may be of double width, the web printed thereby being split longitudinally. Between the lower printing-mechanisms, folding and delivery mechanisms F, G and F<1>, G' are provided. As shown by the courses of the webs in full lines, the printing-mechanisms A<1>, A<2>, A<3>, at the left-hand end, are each perfecting their respective webs x<1>, x<2>, x<3> in black, while the other mechanisms A<4>, A<5>, A<6> are printing the web x<4> in black on one side, and in three colours and a key colour on the other side. The three mechanisms A<4> , A<5>, A<6> may, however, each perfect a web x<4>, x<5>, x<6>, respectively, in black. In order to convert the mechanisms A<5>, A<6> for printing in colours or in black, the second type cylinders t<1> are arranged to be driven in either direction and an additional impression cylinder i<2>, for colour-printing, is provided in conjunction with each cylinder t<1>. Each of the printing-mechanisms comprises the type cylinders t, t<1>, impression cylinders i, i<1>, and suitable inking &c. mechanisms. The printed webs may all pass to the folder F<1> for folding with the colour-printed pages outside, as shown by full lines, thus producing a sixteen-page product, or two sixteen-page products when the mechanisms are double width, the folding-mechanisms being in duplicate side by side. Or the webs from the two sides of the mechanisms may be associated. When perfecting six webs, three may be led to each of the folders F, F<1>, as shown by dotted lines, or all to one folder, or otherwise. In a modified machine, the two upper mechanisms are arranged each to perfect a web in black, and the two lower pairs of mechanisms A', A<2> and A<4>, A<5> are arranged each to print a web in colours, one of which may be associated and folded with each of the perfected webs from A<3> and A<6>. In other modifications, other folding and delivery mechanisms are arranged above the folding-mechanisms F, F<1> so that a very large variety of products may be obtained. Fig. 6 shows a front view of two folders F<2>, arranged above the two folders F. Each folder is provided with a cutting and delivery mechanism G consisting of cutting and associating cylinders 11, folding-rollers 12, S-flys 13, and delivery tapes 14, &c. The delivery mechanisms are arranged as shown, to deliver the products at about the same level and in convenient positions. The webs may be led directly from each folder F or F<2> to its delivery G, or in various ways, as shown by full and dotted lines. As shown by the full lines, the webs from all the folders are led to one delivery G, and in order to permit this mechanism to cut and deal with the thick product, two additional cutting- cylinders 17, 18 are provided, which cut sheets from two of the webs and associate them on the cylinder 15 with the sheets cut from the two other webs by the cylinders 15, 16. The associated sheets are folded through the rollers 19 to the fly 13. The folders may be placed facing each other, instead of back to back as shown in Fig. 1.
