NONCONTACT HEATER FOR WIRE MATERIAL

摘要

A noncontact heater having a case (2) that contains a heating pipe (1) for passing a wire material to be heated and a heat-insulating material layer (3), as shown in the figure. A temperature sensor (7) is disposed in contact with the heating pipe (1) or inside the heating pipe (1). Slits, having a predetermined width or locally widened, are disposed along the entire length of the heating pipe (1), and thus a cover portion of the case opposing slit-like openings of the heating pipe can be opened and closed. Further, in order to restrict vibration and deflexion of the travelling wire material, guides can be inserted into the heating pipe, or the temperature sensor can be fitted to the side surfaces of this guide, and a connection terminal member may be of a split type.
