FIELD: electric heating; structure of flexible heating elements.
SUBSTANCE: flexible heating device has irradiator in form of spiral. Ceramic insulator embrace heating device. Insulators are made integral and they have open grooves made narrowed to provide fixation of radiator. Irradiator is made in form of spiral. Adjacent edges of insulators are brought into contact; the edges are made in form of radius surfaces entering one another. Ceramic insulators are made to have headband to connect insulators together or to fasten them to case.
EFFECT: reduced cost; widened technological abilities; reduced consumption of material; reduced labor input.
