Drive for modular,rotary sheet printing machine - involves several printing units with transfer drum between them, and appropriate gear train

摘要

The printing machine has two drive pinions (14,15) enclosing a specific inner angle (beta), and by allocation of the drive pinions to a gear wheel of an outer printing mechanism the angle is between 60 and 90 deg. By allocation of the drive pinions to a gear wheel of a middle printing mechanism the angle (beta) is between 150 and 170 deg. The double-sized printing and transfer cylinders as against the plate and blanket cylinder are arranged at an angle (alpha) from 10 to 20 deg. By allocation of the drive pinions to a gear wheel of an off-centre printing mechanism, the inner angle (beta) enclosed by the drive pinions is between 90 and 150 deg. USE/ADVANTAGE - For rotary sheet printing machine,with a single drive mechanism and good printing quality.
