Method and apparatus for electric singe cutting

Thin material such as hair or paper is severed by a singeing process using the heated and opposed edges of two thin strips of metal with the edges closely spaced apart to form a slot and with the edges heated by high frequency electrical current or currents flowing along such strips and exhibiting therewith and therebetween skin and proximity effects, and by moving such strips relative to such material so that the material to be singed or severed enters such slot and is therein singed to effect severance by such singeing.
