<p>Heating device for a moving yarn, of the type consisting of an insulating enclosure (15) which surrounds a heating unit (E) with which it defines a longitudinal channel, inside which the yarn (5) to be treated passes, means for guiding the said yarn being provided for ensuring its positioning, the said heating unit (E) consisting of an assembly comprising at least two cylindrical sections (A, B) having different diameters, arranged in the extension of one another and supporting, over their length, rings (1, 3, 4) equipped with guide elements making it possible to keep the yarn at a constant distance from the surface of small diameter and making it possible to cause the yarn to come into helical tangential contact with the cylindrical surface of large diameter. It is characterised in that one of the end faces (31) of the casing surrounding the insulating enclosure and the heating unit is removable and supports the set of connections making it possible to ensure the electrical supply of the oven, its regulation, etc., the heating unit (E) being fixed at one of its ends to the said removable face (31). <IMAGE></p> |
