The shaftless CI flexo printing machine represents a major step forward in modern package printing. Unlike conventional gear-driven systems, this design removes the main drive shaft and replaces it with independent servo motors on each print deck. That architecture places it among the most advanced CI flexo printing machinery available today. As a high-performance Central impression flexo printing machine, it delivers precise registration, reduced waste, and faster job changeovers. The platform shares core engineering with the latest CI flexographic printing machine systems, while the servo-driven shaftless concept makes it a highly flexible CI flexo press for short and medium runs.
The Shaftless CI flexo printing machine is built around a robust central impression drum with a precision-ground, double-wall shell for temperature control and vibration damping. Each color deck is driven by an independent AC servo motor, eliminating the cumulative gear backlash and repeat-length limitations found in mechanical line-shaft presses. The shaftless architecture allows the operator to adjust plate cylinder position, print pressure, and side register from the main control console, reducing setup time by as much as 40%. A chambered doctor blade system with enclosed ink pans works with water-based, solvent-based, or UV inks, delivering consistent ink film thickness at high speeds. The machine handles flexible packaging films such as BOPP, PET, PE, CPP, paper, and aluminum foil, with web tension controlled automatically across the unwind, CI drum, and rewind sections. An advanced pre-registration camera and closed-loop auto-register system hold color-to-color accuracy within ±0.05 mm at speeds up to 250 m/min. The drying system uses high-efficiency hot-air nozzles and optional infrared heaters, with independent temperature control per station. The rewind and unwind units feature pneumatic shafts or shaftless chucks, automatic web guiding, and flying splice options for continuous operation. The integrated control system runs on a Windows-based HMI with recipe storage for up to 1,000 jobs, allowing operators to recall print pressure, register values, and tension profiles. Safety features include full guarding, emergency stops, and interlocked doors on all moving parts. The machine can be configured with 6, 8, or 10 color stations, print widths from 850 mm to 1450 mm, and repeat lengths from 300 mm to 900 mm. Its modular design supports downstream processes such as varnishing, laminating, and slitting inline, helping converters reduce handling and improve output.
