摘要

The device (100) has multiple rollers rotated to move a yarn (Y) and retained in a heat insulating box (23). An air line is arranged at the insulating box and conducts high temperature air in the insulating box to a lower air temperature region in the insulating box. A line inlet and a line outlet of the air line are provided in a door area of the insulating box. The line inlet is arranged at a position with respect to a symmetry plane between the rollers that are symmetrically rotated relative to each other. The air line comprises a flow control unit that controls a flow rate of the air.
