Traveller Weight Selection
topic
Traveller weight is selected to maintain yarn balloon tension within the range that minimises end breakages while ensuring adequate winding-on tension. Heavier travellers increase tension (reducing balloon size, increasing winding tension), lighter travellers decrease tension (increasing balloon, reducing winding tension). Recommended traveller weight tables from manufacturers are based on yarn count (Ne), spindle speed, and ring diameter. Weight is expressed in mg or by a traveller number system (e.g. Braecker C1 series).
Role
Traveller weight selection is the most frequently made engineering decision in ring spinning operations, performed every time a new yarn count runs. Incorrect traveller weight is responsible for approximately 20–30% of end breakages in industrial mills. Systematic traveller weight optimisation — typically requiring 2–3 trials per count — is a foundational process engineering activity.
