ABSTRACT OF THE DISCLOSURE A heater unit of bilateral construction is formed by forming a resistor assembly of a resistor helix extending between cylindrical terminals and overlapping the same, inserting the assembly in a sheath tube, filling the tube with MgO powder, placing laminated mica end plugs over the terminals and extending into the ends of the tube, bending the tube into a U-shape, pressing the legs of the U together and feeding the pressed unit through swaging dies to deform the tube over the entire length thereof to provide a heater unit of substantially circular cross section and having two legs of substantially semicircular cross section. The resistor helix in the area of the leg portions has a cross-sectional shape corresponding to the cross-sectional shape of the sheath and the terminals and mica plugs within the sheath are flattened to provide a similar cross-sectional shape thereby locking the terminals within the sheath.
