Verfahren zur Herstellung technischer textiler Flächengebilde, insbesondere genadelter Papiermaschinenfilze, ohne Grundgewebe oder verstärkende Einlagen

摘要

A method of making a web suitable for use as papermakers' felt including superposing a plurality of fibrous batts such that substantially parallel fibers in one batt extend in transverse direction to substantially parallel fibers in an adjacent batt, needling the superposed batts to form a laminated web, stretching the web to tension the fibers, applying a coating of adhesive to the surface of at least one side of the web, compressing the web, and subjecting the web to a jet of compressed air to break coherent films of the adhesive into globules leaving a portion of the adhesive adhered at points of contact and intersection of fibers on the surface of the web and driving the remaining globules into the web to adhere at points of contact of individual fibers near said surface.
