ABSTRACT:
Machine is provided for the simultaneous laying down/winding of a plurality of rovings, including a gantry supporting a laying down/winding head carrier mechanism plate movable along the X,Y,Z directions, at least one laying down/winding head rotatably mounted on the mechanism plate around at least one vertical axis and comprising a laying down/winding roller, a mechanism for presenting on the roller rovings along at least two tangent laps, selective mechanisms for driving and cutting each roving, and spools delivering the rovings. The spools are mounted on a fixed creel and the rovings are guided between the creel and the head by sets of return pulleys disposed in such a way as to limit the surface scanned by the rovings and reduce the jerks of the roving reeling speed. The machine is especially adapted for production of composite structures.
