Abstract: 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.
Abstract: Liquid crystal polymer films are laminated to a textile substrate in a specific fashion to produce a fabric especially useful for sail panels.
Abstract: A one piece sail is made on a mold and includes an outer impervious layer, such as film, and an inner layer of continuous and uninterrupted yarns disposed in continuous trajectories from one edge of the sail to the other and carrying the majority of the load imposed on the sail.
Abstract: A reinforcing patch is secured to a sail to support the inner ends of battens carried in pockets on the sail. The patch is a laminate having yarns radiating in an omnidirectional pattern from the end of the batten pocket and batten.

Abstract: A laminated sail cloth includes a central layer of spaced intersecting scrim yarns which intersect at acute angles in such a matter to reinforce the fabric along the fill and bias directions of the fabric.
