NOVELTY - Manufacturing a membrane material especially for use in the manufacturing of sails for sailboats and the like, comprises: (a) distributing a first material layer on a vacuum table; (b) dispensing an adhesively coated yarn from a dispenser in a predefined pattern on the first material layer; (c) arranging a second material layer superposed the first material layer and the treads, thus creating a membrane matrix; (d) passing a heating source across the matrix, thus curing the adhesive applied to the yarn and laminating the membrane.    USE - The method is useful for manufacturing a membrane material especially for use in the manufacturing of sails for sailboats and the like, and where the membrane is used in a sail for a craft, vessel or vehicle (claimed).    ADVANTAGE - The method efficiently addresses shrink during curing such that a fully cured membrane may be achieved with negligible shrinkage which also makes it possible to use larger panels and therefore fewer connections between the panels when assembling the panels to a finished sail.    DETAILED DESCRIPTION - Manufacturing a membrane material especially for use in the manufacturing of sails for sailboats and the like, comprises: (a) distributing a first material layer on a vacuum table; (b) dispensing an adhesively coated yarn from a dispenser in a predefined pattern on the first material layer; (c) arranging a second material layer superposed the first material layer and the treads, thus creating a membrane matrix; (d) passing a heating source across the matrix, thus curing the adhesive applied to the yarn and laminating the membrane; where the first material layer is provided with pin holes distributed across the first material layer, allowing the vacuum to traverse the first material layer. An INDEPENDENT CLAIM is membrane comprising two material layers and a distributed yarn sandwiched between the material layers, manufactured according to the method.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a vacuum table.
