Abstract (en)
A sliding roller (N1) for an offset printing machine is constituted by a central shaft (12) mounted such that it rotates on the frame (B) of the machine, and a concentric sliding cylinder (11). A key (14), fixed to the cylinder (11), is engaged with a guidance groove (15) in the shaft (12) to connect the two elements (11, 12) together in rotation while allowing their respective axial displacement. Two chambers (C1 and C2), formed by the cylinder (11) and the shaft (12), can be alternatively put under hydraulic pressure to cause the axial displacement of the cylinder (11) in one direction or the other. <IMAGE>
