ABSTRACT:
A buckling-type paper sheet folder comprises a protective housing (7) and two pairs of folding cylinders (W1, W2, W3, W4) which are mounted in a cylinder frame (1) and conjointly driven by an electric motor (4). Folding pockets (5,6) and the cylinder frame are enclosed on all sides by the housing which has two parts, namely a base (8) and a cover (9), that are hinged and/or detachably connected to each other. In the base, a box-like compartment (12) is formed below the folding pockets accommodating the cylinder frame. The cover comprises a wall (45) extending between vertical side walls (40,41) and covering the upper foldin pocket (5) and having a portion (48) forming the upper boundary of a sheet intake opening. The cover further comprises a second wall (54) extending above the second folding pocket (6) inwardly, to form the lower boundary of the intake opening (51), and having a front portion 39. The parting lines of the vertical housing walls extend at least partly close to the plane of the folding pockets.
