Abstract

The thread deflecting element is provided with an arcuate groove through which the thread passes as well as with compressed air ducts which deliver compressed air at the entrance of the groove on the side within the groove curvature and at a point downstream of the groove apex on the side outside the groove curvature. The air is delivered via ducts within the plate forming the deflecting element. The travelling thread is relieved of a degree of tension in the deflecting element so as to equalize the tension in the two lengths of the thread loop passing over the two heating paths of the heater.
