Rotogravure printing press

for plastic filmfor packagingfor BOPP film

Overview
The shaftless air‑lift plate/cylinder loading rotogravure printing machine is designed for rapid plate or cylinder changeover, precise registration and continuous high‑speed production on flexible substrates. The shaftless concept uses pneumatic chucks and an integrated air‑lift trolley to handle cylinders automatically, minimising manual handling and improving operator safety.

Key advantages

• Shaftless transmission with pneumatic chucks for accurate, repeatable cylinder mounting
• Automatic air‑lift trolley enables single‑operator loading/unloading and faster changeovers
• Changeover time under 5 minutes per station
• High registration accuracy (±0.1 mm) for tight colour superimposition
• Heavy‑duty cast iron frame to reduce vibration at 150–350 m/min
• Solvent‑resistant pneumatic seals and components for extended service life
• Multiple safety interlocks and mechanical fail‑safe locks to secure cylinders on loss of air pressure

Materials and process compatibility

• OPP, BOPP
• CPP, PE
• PET
• PVC
• NY (Nylon)

Applications

• Short‑run and SKU‑flexible food and flexible packaging production
• Wide‑web decorative materials and laminates (e.g., wood‑grain film, decorative films)
• Pharmaceutical packaging including cold‑form blister foils requiring strict registration

Quality & testing highlights
The equipment undergoes runout and concentricity checks (runout < 0.03 mm), pneumatic load testing at 1.5× rated cylinder weight to detect pressure loss and leaks, and registration stability tests with rapid acceleration/deceleration cycles to verify colour superimposition stability.
