Paper and Fabric Finishing Equipment
Paper and fabric finishing sprockets drive the chain mechanisms in calendar rolls, coating heads, drying sections, slitting stations, and rewinder drives. These sprockets require precision bore concentricity for web tension control and vibration-free operation at high line speeds.

Advantages vs Inferior / Working Principle
✅ CNC precision teeth for accurate material feed positioning.
✅ HRC 40-50 hardened teeth — resists material abrasion.
✅ Precision bore 0.025mm TIR — vibration-free operation at production speed.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
Locations: Dryer section chain, calender drive, coater feed, slitter, rewinder. समारोह: Convert motor torque into precise material feed and processing motion.
Compatibility / Selection
ओईएम: Voith*, Valmet*, Andritz*, Brückner* systems. *Compatibility reference only.
चुनना: ❶ Match chain pitch ❷ Shaft bore → hub type ❸ Tooth count for speed ratio ❹ Material grade for environment ❺ Surface treatment for corrosion protection.
Install / Troubleshoot
Install: LOTO → release chain → remove old sprocket → mount new (TL = rapid change) → align → tension 2-3% → lubricate → test.
Issues: Chain riding teeth = worn sprocket (replace both). Vibration = misalignment/bore runout. Excessive noise = dry chain. Chain skipping = elongated chain + worn teeth (replace both).
