CA 2280956

The invention concerns a stretcher comprising a carriage (21) subjected to a back-and-forward motion (2) for depositing in successive segments (2a ... 2d) a web of fibres (2) on an outgoing conveyor (6) moving along a direction (9). In order to produce ranges of different plies in the transverse profile of the lap (4) formed on the outgoing conveyor (6) by the web deposited in mutually overlapping segments, the points of inversion of direction (21) in the backward and forward motion of the carriage are different. As a result the successive folds (2ab, 2cd; 2bc, 2da) of the same direction are differently positioned, and the number of web plies in the lap is not the same over the whole width of the lap. The invention is useful for streamlining the lap freely and accurately.

Un étaleur comprend un chariot (21) subissant un mouvement de va-et-vient (27) pour déposer en segments successifs (2a ... 2d) un voile de fibres (2) sur un convoyeur de sortie (6) se déplaçant selon une direction (9). Pour réaliser des plages d'épaisseur différentes dans le profil transversal de la nappe (4) formée sur le convoyeur de sortie (6) par le voile déposé en segments qui se chevauchent, les points d'inversion du sens de mouvement du chariot (21) sont différents d'un aller et retour à l'autre du chariot. Ainsi, des plis successifs (2ab, 2cd; 2bc, 2da) de même sens sont positionnés différemment, et le nombre d'épaisseurs de voile dans la nappe n'est pas le même sur toute la largeur de la nappe. Utilisation pour profiler la nappe de manière très libre et très précise.
