Guide to guide the doctor blade tip of the squeegees in sheet-fed rotary printing presses

摘要

The guide doctor blades (8) used for sheet work have a comb-type guide doctor blade point (8.1) positioned beneath the cylinder (4) in front of a turning drum (1). In the area between the minimum and maximum sheet format on the guide doctor blade point for guiding the sheet corners of the front edge of the sheet (11), the outward pointing side of the tine is partly outward sloping, seen from the sheet-travel direction.
