ABSTRACT:
There is disclosed an electrically activated infrared source assembly having a frame member with a pair of substantially parallel sides adapted to receive strands of an elongated wire stretched repeatedly therebetween in a serpentine configuration, each side having a curved surface thereon adapted to receive tangentially thereto and to support thereover end portions of the wire strands stretched from the other side, the curved surface having a multiplicity of grooves therealong adapted to accept the end portions of the wire strands at the point of tangential contact for maintaining the stretched wire strands between the sides in a spaced relationship one to another, each of the curved surfaces having a plurality of projections therealong adapted to engage therearound the end portions of the wire strands. An elongated wire is stretched back and forth in a serpentine configuration between the sides, around the projections and along the grooves, the wire being adapted to be connected to an electrical source of pulsating energy and to be activated thereby to radiate pulsating infrared energy. Each end portion of the wire strands is bonded around a projection up to but not including the region of the grooves.
