Abstract (en)
[origin: EP1279896A1] To produce a heater plug, the sealing of the burning zone (5a) with its heating coil embedded in a ceramic filling is given a reduced cross section at the center with radial expansion at the leading end. The shaping is by pressure pads from both sides, with convex and/or concave curved surfaces pressing against the plug.
