摘要
The heating strip (4), at least on its surface (11) facing the overlapping seam, is made of ceramic material. Inside the strip is an electrical heating conductor (6), made from electrical current-conductive ceramic material. The heating strip, at least between the heating conductor and the surface (11), is of heat-conducting ceramic. The heating strip of ceramic material comprises several sections (4a,4b), the temperatures of which are separately controllable. The temperature of the heating strip in the movement direction of the overlapping seam reduces sectionally or continuously. The ceramic material for increasing its heat conductivity is coated with tantalum nitride.
