Abstract

PURPOSE: To eliminate the imbalance between heat supplies to yarns and improve the drawing yield, by heating the draw rollers and heat-setting bath in strting the operation at a temperature higher than that in the normal operation.
CONSTITUTION: In starting the drawing and heat-treating operation, the draw rollers 2 are positively heated to a temperature higher than that in the normal drawing and heat-treating operation. The heat-setting both 3 is also heated at a temperature higher than that in the normal drawing and heat-treating operation. The speed is then increased to the normal drawing and heat-treating one, then the preset temperatures of the draw rollers 2 and heat-setting bath 3 are slowly reduced at the starting of nurmal winding, and the heating of the rollers 2 is stopped after a given time. The temperature of the heat-setting bath 3 is changed to the preset one in the normal drawing and heat-treating operation.
EFFECT: No change in surface temperature of draw rollers and temperature of air surrounding heat-setting bath.
