Abstract
The invention relates to a method for treating fibres, to an installation for treating fibres and thus obtained tape made of treated fibres. The treatment method comprises the steps of continuously supplying a bundle of fibres (1), applying a first resin (51) to the bundle of fibres (1) by electrostatic deposition of particles of the first resin (51), bonding the particles of the first resin (51) to the bundle of fibres (1) by heating, and applying a surface coating to at least one side of the bundle of fibres (1) by depositing filaments of a second resin (91), such that the thus obtained tape made of fibres has a minimum resin load in relation to the fibre used.
