SHEET GUIDE CYLINDER

摘要

The invention relates to a sheet guide cylinder (8) of a sheet-fed rotary printing press, comprising an outer cylindrical surface (15) in the form of a skeleton, a vane ring (19) arranged inside of the outer cylindrical surface (15) and rotatably mounted relativ thereto for generating a stream of air which emerges from the vane ring (19), said stream of air being provided for keeping sheets conveyed by means of gripper systems (11) around said outer cylindrical surface (15) away from said outer cylindrical surface (15). In order to ensure that the sheets are kept away from said outer cylindrical surface (15) with changing operating conditions, the skeleton of the said cylindrical surface is formed by means of guide vanes (30).
