Comma Coater M/C
Electrode film production machine that coats slurry onto release film (PET) with a comma knife and dries it with hot air.
A standard comma coating line with precision servo gap adjustment, a 3-zone hot-air chamber, clean booth and waste-heat recovery — built for stable mass production of high-quality electrode coatings.

Configuration & detailed specifications
Unwinder Part
The controller reads tension sensor values and precisely adjusts tension with an AC servo motor.
Infeed Part
Transports film by air suction. The suction wrap angle achieves high tension without mesh or perforation marks, and a static eliminator bar removes static from the incoming film.
Coater Part
The gap between back-up roll and comma knife is precisely adjusted by AC servo. Digital indicators allow 0.001 mm adjustments to compensate left/right thickness deviation.
Dry Chamber
Electric sheath heaters with hot-air circulation. Optional exhaust waste-heat recovery saves energy. Nozzles combine counter-flow, touch-roll and slitter types.
Outfeed + CPC
The outfeed feeds film stably at constant tension, and the center position controller prevents lateral drift.
Rewinder Part
Winds at constant tension with rotation speed inversely proportional to the rewind setting and roll size.
Clean Booth + Safety Devices
Top-mounted HEPA / ULPA filters minimize particle contamination. Magnetic safety clamps block doors from being forced open during operation to prevent accidents.
Thickness Gauge
Real-time measurement data supports thickness deviation control, process optimization and cost reduction. Includes measurement data logging.
