Abstract

Power consumption is restrained while the temperature of a preheating roller is suitably controlled. A spun yarn drawing apparatus 3 includes: a preheating roller 33 which heats yarns Y before drawn; a conditioning roller 35 which is provided downstream in a yarn running direction of the preheating roller 33 and is higher in temperature and speed than the preheating roller 33; and a thermal insulation box 20 which houses the preheating roller 33 and the conditioning roller 35, the yarns Y being drawn between the preheating roller 33 and the conditioning roller 35, the spun yarn drawing apparatus further including: partition portions 43a and 43b provided between the preheating roller 33 and the conditioning roller 35; a communication passage 47 which causes a low-temperature space 45 which is on the preheating roller 33 side of the partition portions 43a and 43b to communicate with a high-temperature space 46 which is on the conditioning roller 35 side of the partition portions 43a and 43b; and shutters 48 and 49 which are provided to change the flow passage area of the communication passage 47.
