Abstract
Procedure for the manufacture of electrical heating units of the type that have a pair of elongated spiral resistance conductors attached to corresponding terminal elements and surrounded by refractory filler material inside a metal sheath, characterized by the fact that a refractory sleeve is arranged between two terminal elements provided at one end of the resistance coil that the refractory sleeve is crushed during the elaboration of the unit to reduce the cross-sectional area thereof and that the terminal elements are obtained from an essentially shaped element OR.
