Apparatus for fabricating a light control window covering

摘要: A fabric light control window covering in which vanes are adhesively bonded between two sheer sheets such that relative movement the a direction perpendicular to longitudinal of changes angle and, thus, controls amount admitted through shade. The manner tends bias together nonlight admitting position. Also, disclosed methods and apparatus for manufacturing above covering. method features linear application adhesive vane material provides uniform appearance finished product. heat setting process is layers fabrics fed belts over hot cool surfaces, under tension pressure. This temperature-size relationship without inducing wrinkles or distortion into during setting.
