发明名称 Low loss flexible connector for air ducts
摘要 A low thermal loss flexible connector stock material comprises a pair of metal strips, one edge of each of said strips being formed into clamping relation of margins of a pair of foam webs. When the strips are in overlapping relation the webs lie in face-to-face contact, the outermost web being deflected into spaced relation from the innermost web when the strips are folded into co-planar alignment, thereby defining a space between the webs.
