Rieter K44/K45 ComforSpin System
topic
The Rieter ComforSpin system uses a perforated drum (suction drum) positioned after the front rollers, with the drafted fibre band condensed by suction through drum perforations and guided by a stationary suction insert with a narrow slot (1.5–2.5 mm). The condensed band width is 0.5–1.0 mm vs 2–4 mm conventional. Suction is generated by a central vacuum unit at −2,000 to −3,000 Pa. ComforSpin reduces H hairiness by 35–50% and improves tenacity by 8–12%.
Role
The ComforSpin system is the market-leading compact spinning technology and the benchmark against which all other systems are compared. Understanding its mechanism and performance data provides the basis for supplier comparison when specifying compact spinning equipment, and its published quality performance data is the reference for calculating ROI on compact conversion investments.
