A method for the weaving of thicker reinforcement with a plurality of not - detachable layers for composite materials and the weaving machine for the fabrication

摘要

- the invention relates to the weaving reinforcements thick. & br / - the object of the invention is a method for weaving a thick plate with multiple layers delaminable, the structure of type 2,5 or 3 d, in which the warp threads pass successively into a yarn joining comb, in a calibrating comb, and then in a weaving unit with a dobby, characterized in that it separates, upstream of the calibrating comb (27), the warp threads (5) in n superposed plies, & br / (see appended drawing in bopi) & br / & & br / (5) in each tooth of the calibrating comb (27), and is fitted with two adjacent cords of a same tooth of the calibrating comb (27) in the eyelets (11) of two rails (12) of same rank of the two plates of the dobby, so that the planes of the displacement of the two adjacent cords, during the formation of the shed, form between them an angle sufficient to prevent the attachment between the strands. & br / - application to the weaving reinforcements made of composite materials.
