A three dimensional sail of one piece construction is made on a rotating roll having a deformable outer surface. The roll is divided into a large number of segments, extending across the width of the roll, with the convex profile of each segment being adjustable. A sail is made on the roll on a continuous basis by applying a first layer of film, deforming the film on the roll, applying adhesive and reinforcing the yarns, and applying a second layer of film to form a 3-D laminate. |
