Abstract

The heating element has against the whole interior of the cover tube (1) and the insulating material (2), a tube (8) of gleaming mineral. The cross-sectional area of this tube is reduced, its shape being altered by pressing the cover tube along its complete length and across its longitudinal axis. - The pressing of the cover and gleaming tube cross-sectional alters their form from round or oval to one which is pref. six-sided. The resistance wire is wound on a pliable core of insulating material, pref. fibreglass. The resistance wire (3), prior to being fitted inside the gleaming tube, is wound in a screw line formation on a second gleaming tube which encloses a metal tube with essentially smaller cross-sectional dimensions than the cover tube.
