Fig. 38 – Overview of traveler weights

The mass of the traveler determines the degree of friction of the traveler on the  ring and thus the yarn tension. If the mass is too low, the balloon becomes too large, the cop too soft and the amount of material taken up on the cop too small. On the other hand, too high a mass results in high thread tension and frequent ends down. The mass of the traveler must therefore be adjusted exactly to the yarn (count, tenacity) and the spindle speed. If there is a choice between two traveler weights, the heavier one is usually preferred, since this results in higher cop weight, smoother running of the traveler and better heat dissipation. The table (Bräcker, Fig. 38) can be of assistance in approximately defining the traveler number: (ISO is the new standard here and specifies the mass of 1 000 travelers in grams).

The traveller weights are determined beside the yarn number by the following parameters:

 

Yarn twist

Knitting

Lighter travellers

Fibre type

Blends, synthetics

1-2 number heavier travellers

Spindle speed

Higher RPM

Rather lighter travellers

Spinning geometry

Small ring diameter

Small balloon

Lighter travellers

Large ring diameter

Large balloon

Heavier travellers
