Abstract
A plurality of cords of heat resistant material are disposed adjacent to one another in a plurality of layers. A heat resistant tape material having an adhesive formed thereon in a pair of beads is wrapped around the center portions of the cord members so as to form a pair of free hanging curtain sections effective to block gas flows in a heat treatment furnace or the like. The adhesive is also heat resistant, and the use of a tape to form this curtain assembly enables the same to be independent of mounting hardware such as clamped mounting plates. The vertical position of the curtain assembly may be adjustable so as to compensate for wear during use.
