Abstract (en)
The method for producing uni-directional layer (2) with a predetermined layer width from a predetermined number of filament strands (5), comprises spreading the filament strands transverse to longitudinal direction of the uni-directional layer to tape and then arranging to each other. The tape spreads on a width, which is greater than a division width that arises itself from the layer width divided through the number of the filament strands. The tapes fold together after spreading transverse to the longitudinal direction on a tape width, which corresponds to the division width. The method for producing uni-directional layer (2) with a predetermined layer width from a predetermined number of filament strands (5), comprises spreading the filament strands transverse to longitudinal direction of the uni-directional layer to tape and then arranging to each other. The tape spreads on a width, which is greater than a division width that arises itself from the layer width divided through the number of the filament strands. The tapes fold together after spreading transverse to the longitudinal direction on a tape width, which corresponds to the division width. The tape width is smaller than the division width. The tape is arranged transverse to longitudinal direction. The tape spreads and pushes together on tape width, which is greater than the division width. The filament strand spreads in two different plains. An independent claim is included for a device for producing uni-directional layer.
Abstract (de)
Es wird ein Verfahren zum Erzeugen einer UD-Lage (2) aus einer vorbestimmten Lagenbreite aus einer vorbestimmten Anzahl von Filamentsträngen (5) angegeben, bei dem man die Filamentstränge (5) quer zur Längsrichtung der UD-Lage (2) zu Bändchen (16, 17) ausbreitet und nebeneinander anordnet. Man möchte eine UD-Lage (2) mit möglichst gleichförmiger Dicke erzeugen. Hierzu ist vorgesehen, dass man die Bändchen (16, 17) auf eine Breite ausbreitet, die größer ist als eine Teilungsbreite, die sich aus der Lagenbreite dividiert durch die Anzahl der Filamentstränge (5) ergibt.
