Patent

CA 2680457

The invention relates to a spreading device (20) and a spreading method for spreading out fibre filament bundles (32) to form a flat fibre band (14). Problems relating to the material quality of fibre filament bundles (32) to be spread out are solved by repeatedly exposing the fibre filament bundle (32) to at least one convex spreading edge (80).

L'invention concerne un dispositif d'écartement (20) et un procédé d'écartement pour écarter des faisceaux de filaments de fibres (32) de manière à former une bande de fibres plate (14). L'objectif de cette invention est de résoudre les problèmes relatifs à la qualité de la matière des faisceaux de filaments de fibres (32) à écarter. A cet effet, le faisceau de filaments de fibres (32) est disposé de manière répétée sur au moins une arête d'écartement convexe (80).
