DEVICE FOR GUIDING PAPER SHEET IN PRINTING UNIT OF WEB ROTARY PRESS

摘要

A paper web guiding mechanism for printing units in a rotary web-fed printing machine is disclosed. Each printing unit has associated therewith a pivotable paper web guide frame which is comprised generally of spaced side plates. Each side plate is rotatably secured at its lower end to a longitudinal support member of the printing unit so that the paper guide frame can be pivoted between inclined and vertical positions. Paper guide rollers are held between the spaced side plates at the upper and lower ends of the paper guide frame to define a path of paper web travel. A cover sheet extends between the side plates from their upper ends downwardly to a point above the lower ends. This cover sheet supports the body of a press operator who is thus afforded access to various components of the printing units without necessitating severing of the paper web. An operating floor pedestal is placed between the lower ends of the side plates and the press operator can stand on this pedestal.
