Definitions

  • This drive and storage system for the galvanically treated pressure cylinder 1 is provided at one end of an elongated, not shown electrolyte trough 2, which receives the pressure cylinder to be treated.
  • electrolyte trough 2 receives the pressure cylinder to be treated.
  • anodes are arranged in rows in the longitudinal direction of the electrolyte pan 2. The even rotation of the printing cylinder ensures a uniform build-up of the galvanic coating on the printing cylinder.
  • axially resilient centering tip 7 within the quill 4 takes place by means of a cylinder-piston unit, the piston rod of which is not visible in the illustration is firmly connected to a guide body 19 guided in the quill 4, which carries the centering shell 6 and the centering tip 7 and their cylinders 20 is connected to the inner housing 3 via an end connection block 21.
