13. Traveller
• Travels around the ring at (30-35) m/sec.
• The hardness of the running traveler (650-
700) vickers.
• Contact pressure between ring and traveler
is up to 35N/mm².
• Generate high temperature (300-400°C)
• The mass of traveller is 16-120gm/1000.

Factors considered for selection of a
traveler:

15. Main advantageous features of ring
spinning machine:
• Most usable spinning machine in the
world.
• Fine to coarse (5-1000 tex) yarn can be
produced.
• Yarn has very good strength.
• Yarn is suitable for all next process.
• More than 80% of total yarn is
produced by ring spinning machine

16. Limitations of ring spinning:
• Low twisting rate
• Low production
• Small bobbin size
• Frequent doffing
• High energy consumption
• Limited speed of traveller
