Lateral sealing device for doctor blade inking chambers of inking rolls for flexographic rotary printing machines

摘要

The cassette has a casing consisting of a parallelepiped carrying two outwardly projecting tabs (105) at its ends and having an internal hollow housing closed by an end wall and two side pieces. A cavity (206) has a channel for housing a spring in the form of an open ring of spring steel wire. The spring presses a seal interacting with an inking roll against the periphery of the inking roll with a constant force.
