1,219,409. Folding paper. CAMCO (MACHINERY) Ltd. 9 May, 1968 [12 May, 1967], No. 22227/67. Heading B8R. A paper sheet folding machine comprises a plurality of separate fold sections for effecting a plurality of folds in directions lying at right angles to one another, a final fold section in the form of a separate and removable unit being arranged to be usable in any one of at least two alternative positions on the machine to which each partially folded sheet can be directed from a previous fold section of the machine. (1) A sheet is fed on a conveyer 14, Figs. 7 and 8, to a buckling folder 19, 20, 20a, which folds it transversely. A plurality of buckling folders are provided if a plurality of transverse folds are required. (2) The folded sheet is fed on a conveyer 22 to below a reciprocating knife folder 28 movable downwards by a pneumatic or hydraulic mechanism 32 and co-operating with rollers 29 to fold it again along a line parallel to frame side plates 10, 11. (3) The twice-folded sheet is fed by a conveyer 34 to one of the folders F3a or F3b, each of which comprises a reciprocating knife 42 or 44 operated by a pneumatic or hydraulic mechanism 43 or 45 and co-operating with common rollers 46 to fold it along a line transverse to the plates 10, 11. (4) A fourth folder F4, Figs. 7, 8, 9, is in the form of a detachable unit with extensions 58, 63 which pass through one of four apertures such as 48, 49 of which there are two in each side plate 10, 11. If the folder F3a is in use, one of the apertures in the plate 10 is used, according to which direction the sheet is to be fed for receiving the fourth fold. As shown, the folder F4 is in the aperture 48 and the sheet is first fed parallel to the plate 10 against a side lay 72 and then transverse to the plate 10 to come below a reciprocating knife 55 operated by an hydraulic or pneumatic mechanism 56 and cooperating with rollers 57 to fold it along a line parallel to the plate 10. The sheet is then removed by a conveyer 80 in a form comprising 32 pages. The knife folders are actuated when a photo-electric device senses the arrival of a sheet. The insertion of the folder F4 may control the drive to the reversible conveyer 40. According to the position of the folder F4, the layout of pages obtained may be standard United Kingdom, United States, German or other.
