Abstract

La présente invention concerne notamment un procédé de réalisation de préformes comprenant l'application d'un liant sur au moins une fibre (9) sèche continue, chaque fibre étant formée à partir d'au moins deux fibres initiales distinctes, et le drapage de ladite fibre munie de liant au moyen d'une tête de drapage pour former une préforme. L'application de liant est réalisée au moyen d'une buse de fibérisation (50) comprenant un orifice de décharge (53) alimenté en liant liquide ou pâteux, et un ou plusieurs orifices d'injection (57) alimentés en gaz sous pression, de sorte que ladite buse soit apte à délivrer le liant sous la forme d'un filament en spirale (92), les spires de filament se déposant sur la fibre défilant en vis-à-vis d'une buse pour obtenir une fibre munie de filaments (93) de liant, lesdits filaments de liant assurant une liaison entre les fibres initiales.The present invention relates in particular to a method for producing preforms comprising the application of a binder to at least one continuous dry fiber (9), each fiber being formed from at least two distinct initial fibers, and the draping of said. fiber provided with binder by means of a draping head to form a preform. The binder is applied by means of a fiberization nozzle (50) comprising a discharge orifice (53) supplied with liquid or pasty binder, and one or more injection orifices (57) supplied with pressurized gas, so that said nozzle is able to deliver the binder in the form of a spiral filament (92), the turns of filament being deposited on the fiber passing vis-à-vis a nozzle to obtain a fiber provided with binder filaments (93), said binder filaments providing a bond between the initial fibers.
