Abstract
Investigations on industrial Noble combing practice reveal excessive variations in both tear and rate of production and emphasize the need for a satisfactory means of controlling the comb. A suitable method is described and shown to reduce the range of the variations in production within comb loads from more than 25% to less than 5%. The device also permits rapid estimation of the rate of production—tear curve, and hence the optimum rate of combing, for a particular batch of wool and, when set, will maintain the comb at that rate.
