This heating film is of the type formed by a support sheet which holds captive heating metal bands. According to the invention, it comprises on the one hand two lateral conducting bands (5), at least one of which forms regular loops (6), that is to say successively moves away from and draws close to the other band (5), delimiting, between the loops (6), portions (7) of film (2) where the bands (5) are close to one another and are parallel, and on the other hand heating bands (8) in a zig-zag shape which are connected by their ends to these two lateral bands (5), which occupy the greater part of the surface delimited by said loops (6). <IMAGE> |
