Abstract

PURPOSE: To eliminate the trouble, e.g. complete breaking or wrapping around stretch-breaking rolls, by increasing the stretch-breaking ratio between the delivery rolls and breaking rolls set at a low value in threading gradually to a given value.
CONSTITUTION: The undrawn tow T from the tow can 1 is passed through the guide 2, and feed rolls 3 and 4, and stretch-broken between the delivery rolls 6 and 7 and stretch-breaking rolls 9 and 10 at a ratio of 10W40 while being heated by the heater 8. The stretch-breaking ratio of T between the rolls 6 and 7 and rolls 9 and 10 is set initially at a low value, and the tow T is threaded. The ratio is then increased gradually to a given value, preferably by increasing the rotational speed of the rolls 9 and 10 at a constant speed of the rolls 6 and 7, or by reducing the speed of the rolls 6 and 7 gradually at the constant speed of the rolls 9 and 10.
