Abstract

A filament winding machine and method for winding a fibrous ply onto a body, the machine comprising at least one winding head having a final guide member, a movement system capable of rotating the body and of moving the body relative to the winding head, and a resin application system capable of applying a resin composition to the fibrous ply. The resin application system comprises a nozzle capable of coating one of the main faces of the fibrous ply with a resin composition upstream of the final guide member and a feed device capable of supplying the nozzle with the resin composition at a flow rate that is regulated according to the travel speed of the fibrous ply.

Dependent claims

A Filament winding machine for winding a fibrous web comprising at least one continuous fiber, onto a body the machine comprising

winding means comprising at least one winding head associated with fiber storage means and comprising a final guide member
a displacement system able to drive the body in rotation and to effect a relative displacement of the body with respect to the winding means for winding the fibrous web onto the body, and
a resin application system able to apply a resin composition to the fibrous web,
wherein the resin application system comprises application means comprising at least one nozzle able to coat one of the main faces of the fibrous web with a resin composition, at the winding head, upstream of the final guide member and a feed device able to feed the resin composition to the said nozzle at a rate which is regulated depending on the speed of the fibrous web.
