Patent ID: 7446286

Claim:
A method for manufacturing a heater strip to be used as a heating element in an electric heater or heating module comprising: providing a support or base body, forming the heater strip as a profiled strip from a metallic material forming a resistor section, forming a plurality of mounting elements for mounting the heater strip onto the support or base body, wherein said mounting elements extending over one common longitudinal side of said resistor section and being made as one piece with the resistor section form the flat metallic material, the strip is formed in a zigzag structure with leg sections between bend areas of the zigzag form such that the mounting elements are provided only on the leg sections, and the mounting elements are formed on one longitudinal side of the resistor section by cutting or punching from the metallic starting material in a cutting or punching station positioned exactly to the zigzag-shaped profiling and positioned exactly to the leg sections.
