Abstract
The wear of ring travellers is important because it prevents the use of higher production speeds in ring spinning. This wear is probably affected by the body temperature of the traveller and an analysis is quoted which shows that a factor which has a very large effect on the body temperature is the division of heat between the traveller and the ring. To investigate this an experimental apparatus has been constructed which effectively rotates the ring and keeps the traveller fixed. It is thereby possible to estimate the division of heat between the two surfaces and to estimate its effect on the rate of wear.
The results of the experiments are still not conclusive but it has been shown that the pressure has a much more important effect on wear rate than does speed. The pressure also has a cumulative effect since it very drastically affects the division of heat between the two rubbing bodies so that high pressures and high temperatures are produced simultaneously.
