Shaftless semi-rotary offset label printing machine

This printing machine offers a combination of Japanese offset printing technology and Wanjie’s intermittent rotary technology.

Shaftless Drive – The main control unit manages the performance of the independent servo drives, which ensures a very fast and accurate response at high speeds.

Printing Unit – In every printing unit there is a touch panel for independent adjustments, making eaier for the operator the set-up process. Once the printing repeat has been selected, every printing unit moves automatically to the printing position. The 210º structural design of the printing cilynders avoids the inherent problems of pressure setting.

Offset Ink Train – A very robust ink train guarantees the colour stability and print sharpness at any speed. By using a water oscillating roller in contact with the water-ink form roller it can be reached quickly the desired ink-water balance preventing the undesired bars and ghosting. The ink train is composed by 20 rollers, including:

  • 4 oscillating roller
  • 4 distributor rollers
  • 4 ink form rollers

Semi-automatic plate change – The offset plated is changed semi-automatically. During its change, the movement and position of the cylinders and the grippers manoeuvres is electronically controled, shorthening up to 6 minutes a complete change over time for a six-colour machine.

Lubrication system – The machine is equipped with an automatic oiling system to ensure the life time of the machine.
