Abstract:
1. A folding device for folding printed products in printing presses and folding machines comprising a folding table having a length that extends in a product feed direction and a width that extends perpendicular to said product feed direction, at least one stop associated with the folding table, a plurality of transfer belts for engaging and transferring printed products in said product feed direction onto said folding table to said at least one stop, a pair of rotatably driven folding rolls, and a folding blade moveable relative to the folding table in synchronism to the transfer of printed products to the at least one stop, wherein said transfer belts are guided by belt guiding elements which are moveable in a direction perpendicular to said product feed direction and perpendicular to said width of the folding table such that the transfer belts are moveable between a lowered position in which the transfer belts form a full area contact with the folding table for fixing the printed product on the table during a folding operation and a raised position relative to the folding table, and wherein the folding table has a sheet receiving area in a first folding table plane where printed product is folded by the folding blade, printed product to be folded being fed from an inlet section of the folding table to the sheet receiving area in the product feed direction and the folding table has an outlet section in the region of said stop that extends lower than the folding table plane as the outlet section extends in the product feed direction away from the sheet receiving area.
