ABSTRACT:
An extensible and collapsible covering (10) for framed openings. A shade, having periodically emplaced elastic rod stiffeners (28), is motivated over parallel tracks (20) by a movable sill (26). During shade manufacture, stiffeners (26) are inserted into shade pockets by a machine (100) which examines the fabric, excises flaws and creates pockets for the envelopment therein of the stiffeners. The process for flaw removal uses a single pass technique that cuts fabric around a stiffener, reforms it and bonds the cut ends so as to capture the stiffener in a pocket formed thereby.
