Abstract
A method for fibre placement with the aid of a roller is provided. The roller is able to pivot about a rotation axis and to lay a plurality of first pre-impregnated fibres on second pre-impregnated fibres of a laying surface by rolling over said laying surface. The first fibres being distributed along a lower generatrix of the roller and being in contact with an outer surface of said roller over a contact arc. The method includes cooling the first pre-impregnated fibres in contact with the roller so as to enable them to slide on the outer surface of the roller and heating the second pre-impregnated fibres of the laying surface that are located at the front of the roller so as to promote the adhesion of the first fibres to the second fibres of the laying surface.
