Abstract
Attention is drawn to the complexity of the theory of friction-twisting and to the practical difficulties encountered in obtaining satisfactory yarn quality with friction twisters at high production speeds. This is contrasted with the simplicity and reliability of pin twisters. Recent improvements in the design of pin twisters are explained, and these are offered as an explanation for the dominant position that these twisters hold at present and, in the opinion of the author, are likely to retain for some considerable time. The paper concludes with a reference to recent work that has shown that friction twisters with a built-in twist-control system may be the ultimate method of carrying out the false-twist process at very high speeds.
