Abstract (en)
[origin: EP0205115A2] In a folding machine installed on a web-fed printing press for the manufacture of products with at least two cross-folds, having a cross-cutting unit (6) followed by two sequential cross-folding units (8 and 9), the necessary number of controlled sub-units may be simply reduced to give a simple and operator-friendly design in that only one (8) of the cross-folding units (8,9) consists of a folding blade (16) mounted on a cylinder (15) and a jaw folding unit interacting with these, comprising folding jaws (18) fitted to a subsequent cylinder (17) and the other cross-folding unit (9) is constructed as a buckle-folding device consisting of three rollers (21, 22, 23) driven at the same peripheral speed and parallel to the cylinders (15, 17) of the jaw folding unit, which delimit two adjustable transport gaps (24, 25) offset relative to one another on the periphery of the middle roller (22) and a passage (26) situated opposite the middle roller (22) and flanked by the two peripherally non-contacting outer rollers (21, 23), to which passage a buckle pocket (20) open to the middle roller (22) and extending over the full length of the roller is attached, this buckle pocket consisting of guide walls (27,28) separated from one another and directed towards the outer rollers (21, 23) and a stop plate (29) adjustable along the guide walls and bridging the distance between them. <IMAGE>
