摘要

#CMT# #/CMT# The plate (6) has a fixing head (22) for fixing to a printing/plate cylinder (4), and a spigot (24) for fixing to the cylinder. The fixing head includes a maintaining projection i.e. boss (28), for cooperating with a maintaining element (34) of the cylinder. The boss is fabricated in a single sheet block with the fixing head and is arranged in the plate. The boss has a longitudinal shape extending along a free edge (26) of the head. #CMT# : #/CMT# An independent claim is also included for a printing assembly comprising a maintaining device. #CMT#USE : #/CMT# Printing plate for use in a printing assembly (claimed) for a rotary printing press. #CMT#ADVANTAGE : #/CMT# The fabrication of the boss in the single sheet block with the fixing head of the plate reduces fabrication cost of the plate. The configuration of the plate allows for increase in retaining forces to retain the plate on the printing cylinder and permits rotation of the cylinder at high speed e.g. 60000 rotations per hour. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed enlarged view of a printing assembly provided with a printing plate. 4 : Printing/plate cylinder 6 : Printing plate 22 : Fixing head 24 : Spigot 26 : Free edge 28 : Boss 34 : Maintaining element.
