The invention relates to a system for the drape forming of bands of composite material (3), consisting of: an unwinding head (20), an original assembly comprising a light source (4) which is used to heat the band (3) and to harden the composite, and a pair of rollers (6a and 6b) which apply the desired pressure in order to assemble the band with a pre-deposited laminate (2) or to apply same to the support (1). Since the application of heat is concentrated at a distance from the rollers (6a and 6b) and with a normal incidence thereto, said rollers can be made conveniently from an elastic material. As a result, the rollers can adapt well to the cross curvature of the support tool (1) and apply a uniform pressure.
Le système de drapage de bandes de matériau composite (3) comprend, outre une tête de déroulement (20), un ensemble original composé d'une source lumineuse (4) pour échauffer la bande (3) et durcir le composite et une paire de rouleaux (6a et 6b) appliquant la pression voulue pour assembler la bande à un stratifié (2) déjà déposé ou l'appliquer sur le support (1). Comme l'application de chaleur est concentrée à distance des rouleaux (6a et 6b) et avec une incidence perpendiculaire, ceux-ci peuvent être construits en matière élastique sans inconvénient, ce qui leur permet de bien s'adapter à la courbure transversale de l'outillage (1) de support et d'appliquer une pression uniforme.
