Folding apparatus super structure for roll printing machine, has driving unit provided on same side of wall similar to that of support axle and cylinder for directly driving cylinder, where support axle is connected to wall

摘要

The super structure has a cylinder (10) mounted in rotation on a support axle (11) whose end is rigidly connected to a wall (13) of the super structure. A driving unit (14) is provided on a same side of the wall similar to that of the support axle and the cylinder for directly driving the cylinder (10), where the axle is connected to the wall. A driving shaft (15) of a motor (16) of the driving unit (14) includes an output pulley (17) that drives an input pulley (18) associated to the cylinder, by a belt (19).
