摘要：<p>The flowing gas is esp. air. A winding machine is used which may be of a known type but which is provided with additional devices. a heating wire is spirally wound on an insulating strip. At the same time as the wire is wound, a notch (7) is pressed in one of the long sides of the strip (6), and the heating wire is wound in it under tension and firmly fixed in it. Winding turns are shaped by two shaping elements (8), somewhat narrower than the insulating strip (6). They are placed during winding on both sides of the strip (6) inside the winding (9).</p>
