A composite sheet includes a base layer and a surface layer. A surface layer is comprised of continuous fibers and extends along a longitudinal axis of the composite sheet. The surface layer is attached to at least one surface of the base layer along a first attaching lines extending at intervals in one half region of the surface layer defined by the longitudinal axis and a second attaching lines extending at intervals in another half region of the surface layer. The first and second attaching lines are extending in a direction intersecting the longitudinal axis.

Cette feuille composite sert à la fabrication de chiffonnettes (1) ou analogues. Pour la réaliser, on applique sur une couche de base (7), au niveau d'une ligne de jonction (5), des fibres continues groupées (8a). Cette ligne de jonction (5) se compose d'une première ligne de jonction (5A) réalisée d'un côté d'un axe C-C formant une bissectrice pour la largeur des fibres continues groupées (8a), et une seconde ligne de jonction (5B) réalisée sur l'autre côté. La première et la seconde des lignes de jonction (5A, 5B) coupent en oblique les fibres continues groupées (8a) de façon à se couper les unes les autres en progressant vers l'axe C-C.
