Gearless stack flexo press technology has become a core choice for label, flexible packaging, and folding carton converters that need repeatable colour without gear marks, lower setup waste, and reduced mechanical maintenance. Our portfolio covers four distinct build levels. The Central impression gearless flexo press is engineered for high-quality process work on extensible films and unsupported materials. The Gearless inline flexo press is designed for rapid job changes and shorter runs where flexibility matters most. For converters targeting maximum throughput, the High speed gearless flexo press offers elevated production speeds and reinforced dryer capacity. The Fully automatic gearless flexo press adds automated wash-up, pre-register, and defect detection to minimize operator intervention. Each press is built on a servo-driven stack architecture with independent print decks, precision sleeve mounting, and a digital control platform that manages tension, register, and drying in real time. The open-frame design simplifies web path access and supports surface printing on BOPP, PET, PE, paper, and carton board.
The Gearless stack flexo press is available in several build levels so converters can match speed, automation, and drying capacity to the job mix. A standard configuration includes individual AC servo drives on each colour deck, sleeve-type print cylinders with air-assisted mounting, motorized longitudinal and transverse register, and closed-loop tension control with load cells or dancer rollers. The stack architecture keeps the web path open for easy cleaning and rapid sleeve changes, while the gearless drive eliminates backlash and gear marking on high-coverage solids and fine vignettes. The main drive system uses AC servo motors with fibre-optic communication, and each deck can be jogged, registered, or washed independently while the press is stopped. Automatic pre-register reduces setup waste to under one repeat length on most jobs, and the optional camera-based register control maintains colour-to-colour accuracy even at speed. Quick-change anilox and doctor chamber systems allow a complete ink change in under ten minutes per deck.
