Abstract
A steam-iron sole-plate comprises a first plate constituting the sole-plate proper and provided with a roll-bonded layer of brazing alloy, a second plate constituting the steam chamber and provided with a roll-bonded layer of brazing alloy and a flat resistance heating element inserted between the two plates and separated from these latter by insulating layers. The two plates are assembled together by means of a fluid-tight peripheral brazed joint and a series of brazed joints at the level of bosses formed on the second plate.
