Method for manufacturing a membrane material especially for use in the manufacturing of sails for sailboats and the like, where said method comprises the following steps:a) distributing a first material layer on a vacuum table;b) dispensing an adhesively coated yarn from a dispenser in a predefined pattern on said first material layer;c) arranging a second material layer superposed the first material layer and the treads, thereby creating a membrane matrix;d) passing a heating source across the matrix, thereby 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.
