Print Stations (top loading print unit) including laser engraved ceramic anilox rolls with helical gears, print cylinders, and high precision ground impression cylinders.  Including chiller impression cylinder of 37” circumference for short web path and reducing of material when setting up the press.  The short web path reduces material costs and waste and is driven by a mechanical belt drive, providing a circumferential register of +(-) 25mm

 

19mm gauge steel manufactured print station side frames engineered to high precision tolerances, which sit on a side frame platform

25mm web stressed steel profile side frames on the die cutting stations, designed for excellent stability

The print cylinder and anilox rollers have a top loading design, which allows for quick change over

Constant turning anilox rolls with automatic throw-off without loss of register when the press stops

High precision ceramic anilox rolls

Quick change tool-less ink tray, which is pneumatically released from the print unit for colour change, in all print units

Quick change anilox roll facility

Fine adjustment of plate cylinder

Running lateral adjustment (Manual) model.  Once the machine has been set by the operator, the print will stay in register.
