Abstract
In combination, a drawing apparatus and a crimping apparatus. The drawing apparatus comprises integral first and second draw rolls, with attendant separator rolls, and a draw pin. The final draw roll is fluted around its peripheral surface. The draw rolls are driven from the same source as the crimp feed rolls, and in order to control yarn tension at the crimp feed rolls a variable drive means is provided for the draw rolls, to alter their speed with regard to the speed of the feed rolls. A yarn heater is positioned between the final draw roll and the crimp feed rolls, or in the alternative, between the final draw roll and its separator roll.
