Abstract (en)

The acceleration by a roller of an accompanied flow running from an yarn inlet to a yarn outlet of a thermal insulation box along the running direction of a yarn is restrained, and heat energy loss due to the discharge of hot air through the yarn outlet is restrained as much as possible. A heating-drawing unit 7 includes a thermal insulation box 16 having a yarn inlet 16a and a yarn outlet 16b and five godet rollers 11a to 11e which are yarn heating rollers. A yarn Y introduced into the thermal insulation box 16 through the yarn inlet 16a is wound onto each of the five godet rollers 11a to 11e at a winding angle of less than 270 degrees. For each of the five godet rollers 11a to 11e, a flow blocking plate 30 is provided to extend from the outside of the roller 11 toward a yarn separation position P1 on the outer circumference of the roller 11.
