Abstract: A reliable, wear-resistant sealing for a collecting and folding cylinder includes, on each folding blade shaft, a disk (4) which has a sealing ring (13) arranged on the collar of the side facing the oil space (6) of the folding cylinder (1). The disk (4) can be pressed by means of a clamping ring (5) arranged on the folding blade shaft (2) against a covering disk (3) eccentrically arranged on the shaft (2). The disks (3, 4) are rotatably connected with one another via a bearing (11) and a stud (12). An additional sealing ring (17) is provided at the collar of the side of the covering disk 3 facing the oil space (6).
