Реферат: 7278. Goss, S. G. April 19. Cutting, associating, and delivery apparatus ; folding paper.-Relates to the cutting and folding &c. mechanism of web printing machines, and consists of means whereby the inner sheets of sheets associated for folding together are cut a little shorter than the outer ones, so that, when folded, the edges of the sheets more nearly coincide. Fig. 1 shows an arrangement in which the web 35 passes from the longitudinal folder 30, 31, 32 round a cylinder 19 to the cutting and folding cylinders 7, 8. The cylinder 7 has folding-blades 11 and carrying-pins 16, arranged and operated in the usual way. The cutting-blades 12 and grooves 13 are set rather less than 180‹ apart, so that the sheets cut are alternately longer and shorter. The shorter sheets are stripped off the cylinder 7 by strippers 17, and pass under the tapes 26 to the cylinder 19, on which they are associated with the longer sheets, as yet uncut from the web, and pass therewith to the cutting-cylinders 7, 8. Tapes 22 hold the sheets on the cylinder 19. The associated sheets are folded by one of the blades 11 into the rollers 18. The bearings of the shaft 20 of the cylinder 19 are adjustable by screws 36 for varying the length of the path of the shorter sheets, to obtain correct register. The blades 12 and grooves 13 are preferably set a little to one side of the central line of the blocks 14, 15, so that, by turning the latter round in their seats, the blades and grooves may be brought into position for cutting sheets of equal length when they are not to be associated.
