The printing units of the ALVAR® gear series feature mechanical gear wheel printing units with controlled drive thanks to minimised control technology. The force is transmitted from the impression cylinder to the format cylinder and screen roller via gear wheels and an optimum synchronisation of all rollers is achieved.
The printing units of the ALVAR® gear series are designed for a working width from approx. 1200 mm, with an adjustment of the maximum working width being made according to the customer's specifications. They are low-maintenance, easy to operate and can also be operated by employees without a substantial knowledge of printing. The infeed, i.e. the adjustment and fine adjustment, is carried out mechanically by hand. The printing units are equipped with a pneumatic pressure on/off function and with a continuation function, which prevents the inks from drying up during longer interruptions in printing. Format cylinders from other printing units provided by the customer can continue to be used. We equip our printing units according to your specifications with the appropriate cylinder supports.
