Abstract

The heater (1) with a flat resistance heating element (20) has two longitudinal contact areas (4,4'') spaced across the resistance. The resistance has a standard area (8) and a special area (10), the latter having a different spacing between the contacts. The heater has insulating strips (16,16) to separate the standard and special areas. The electrical conductivity of the heating element is different in the special area.
