Sheet-fed offset rotary printing machine

摘要

The invention relates to a sheet-fed offset rotary printing machine, consisting of a plate cylinder, a blanket cylinder and an impression cylinder. The object of the invention, to avoid the plate and blanket cylinders being lifted out in the functional clearance during the printing process in a sheet-fed offset rotary printing machine, is achieved in that a normal force, which results from the weight of the plate cylinder and the cosine of the cylinder engagement angle and the weight of the blanket cylinder and the cosine of the engagement angle and is assigned perpendicular to the cylinder surface, is greater than the contact force, directed against the normal force, between the plate cylinder and the blanket cylinder and between the blanket cylinder and the impression cylinder.
