Abstract
A flexible curved window is made by arranging a plurality of fine size elongated rods in a parallel manner. A plurality of strings interlaced between alternate ones of the rods to form a matt-like base structure and a flexible liquid absorbent sheet material wetted with adhesive is applied over the surface of the matt-like base structure and then trimmed to fit the size of the latter. When the adhesive is dried and set the contraction of the sheet material causes the blind to curve towards the surface having the sheet material.
