For packaging printers who need fast job changes and tight register on flexible film, the Central impression gearless flexo press combines a temperature-controlled drum with servo-driven print sleeves that eliminate gear marks. When working with board, paper sacks, or multi-layer laminates, the Gearless stack flexo press provides independent vertical decks for reliable drying between colors and stable web tension at high speed. For label and carton workflows that require coating, die-cutting, and cold foil in one pass, the Gearless inline flexo press offers modular rail-mounted stations that can be added or removed without resetting registration. At the top end of productivity, the High speed gearless flexo press reaches 400 m/min with automatic wash-up, pre-registration, and impression setting on every deck.
The Fully automatic gearless flexo press is designed for flexible packaging, shrink sleeves, labels, and paperboard printing. The machine uses a cantilever sleeve system on each print station, which allows one operator to change a sleeve in under two minutes without lifting equipment. Servo motors are water-cooled and sealed to prevent ink mist ingress, ensuring long service life in continuous production. The direct-drive anilox and plate cylinders are synchronized electronically, so mechanical gears are removed from the print path. This gearless design also reduces noise levels to below 78 dB(A) at full speed.

Additional machine specifications:
All servo axes on the Fully automatic gearless flexo press are synchronized through a motion controller with a cycle time below 1 ms. This keeps print length deviation under 0.02 mm during acceleration and deceleration. The system supports doctor blade chamber positioning, anilox sleeve change, and plate sleeve change without tools. For flexible packaging lines, the press can be equipped with a downstream solventless laminator or a water-based coating unit. For label production, rotary die stations, cold foil units, and screen printing modules can be inserted between print decks. The machine frame is cast iron with thermal stabilization to maintain geometric accuracy from 15°C to 40°C ambient temperature. Electrical cabinets are sealed to IP54 and include air conditioning for tropical environments. The fully automatic gearless flexo press accepts sleeve tools from common suppliers and stores up to 500 job recipes in the HMI memory. In addition, automatic ink viscosity control, doctor blade chamber washing, and sleeve cleaning systems reduce manual intervention during shift changes. The press can be connected to a central ink supply, a solvent recovery unit, or a water-based ink circulation system. For high-speed film applications, the optional reverse-angle doctor blade chamber maintains consistent ink transfer at speeds above 300 m/min. Tension zones are isolated by nip rollers, and each zone has independent PID tuning. The servo-driven rewind can handle either surface or center winding, with taper tension adjustable from 0 to 100 percent. Alarm history, maintenance schedules, and production reports are logged and can be exported through USB or Ethernet. Optional remote access allows service engineers to diagnose parameters over a secure VPN connection.
