Abstract
A heating element 4 which is subjected to uneven cooling, as is e.g. the case for the heating element which in the printer in a strip-chart recorder is used for melting itself through the wax layer in order to draw a curve on the strip, has its uneven cooling compensated by the heating element being made from a material having PTC properties, by the electrodes 12, 13 deposited on this material being deposited in such a way that the direction of the electric current is orthogonal relative to the longitudinal direction of the elongate heating element, and by the heating element being dimensioned such that its operating temperature is in the temperature interval having a positive temperature coefficient. Hereby, the parts of the heating element subjected to particularly strong cooling will be passed by a higher current than the parts not subjected to cooling, whereby the heat is generated without delay exactly where it is needed. <IMAGE>
