RESISTIVE MATERIAL MANUFACTURING PROCESS Russian patent published in 1997 - IPC

FIELD: electrical engineering; manufacture of polymeric heating elements. SUBSTANCE: method involves production of heater conducting material in the course of single cycle by applying conducting layer on glass fabric on one side in one or more layer-by-layer processes. Conducting layer is distributed by means of pair of rollers mounted in a spaced relation affording desired layer thickness. Second roller along drawn-out glass fabric path is locked. Bath with compound is mounted above rollers, drying and curing is made in different chambers. Clearance between rollers is increased by definite value for each next application of conducting layer. EFFECT: reduced power requirement. 2 cl, 1 dwg, 2 tbl
