Die Führungskomponente kann aus Kunststoff, Metall, Glas und/oder aus einem anderen, einem Fachmann als sinnvoll erscheinenden Material bestehen und kann auch beschichtet sein. Weiterhin kann die Führungskomponente drehbar angeordnet sein.It It is proposed that the coating unit at least one Fiber strand with the additive before feeding at least one fiber strand in a Faserstrangzuführeinheit the extruder device coated. This can be structurally simple and cost-effective ensure efficient pre-coating. Under one Vorimprägniervorrichtung is to be understood here a device that has a fiber strand, either a short glass fiber, a roving or an endless fiber strand and / or another that appears appropriate to those skilled in the art Fiber strand represents, before an actual process step, such as a complete coating, preimpregnated. For preimpregnation is an additive that is either a thermoset or thermoplastic, a resin and / or another, the expert appears useful Additive, in viscous and / or liquid form on the fiber strand applied. A coating unit preferably comprises at least an applicator which applies the additive to the fiber strand applies, and / or a moving device that the fiber strand in at least one other direction of movement in addition to a drive direction moves. The applicator can in the Shape of a chute, an applicator, a nozzle and / or another, the expert appears appropriate sense applicator be educated. The movement device is preferably a vibrating unit, a Hubeinsteller, a gate and / or another, the expert as a seemingly appropriate movement device. A feeder unit advantageously comprises at least one guide component, which on a Away from the coating unit to a fiber strand feed unit an extruder device is arranged. The guide component can be made of plastic, Metal, glass and / or from another, a professional as meaningful appearing material and may also be coated. Furthermore, the guide component be rotatable.
Des Weiteren wird vorgeschlagen, dass eine Düse vorgesehen ist, die den Zusatzstoff auf den Faserstrang aufbringt, wodurch eine gleichmäßige Aufbringung des Zusatzstoffs, beispielsweise in der Form eines Films, auf die Faserstränge erzielt wird.Of Furthermore, it is proposed that a nozzle is provided which the Add additive to the fiber strand, creating a uniform application of the additive, for example in the form of a film, to which fiber strands is achieved.
Ferner ist es vorteilhaft, wenn die Beschichtungseinheit ein Gatter aufweist. Dadurch können die Faserstränge in zumindest einer weiteren Bewegungskomponente in beispielsweise senkrechter und/oder horizontaler Richtung zusätzlich zu der Bewegungskomponente in der Antriebsrichtung bewegt und/oder ausgerichtet werden, wodurch ein gutes Beschichtungsergebnis erzielt werden kann. Unter einer Antriebsrichtung soll hier die Richtung verstanden werden, in die der Faserstrang vor der Vorbeiführung an der Düse bewegt wird.Further it is advantageous if the coating unit has a gate. Thereby can the fiber strands in at least one further movement component in, for example vertical and / or horizontal direction in addition to the movement component be moved in the drive direction and / or aligned, whereby a good coating result can be achieved. Under one Drive direction should be understood here the direction in the the fiber strand before the passage at the nozzle is moved.
Vorteilhafterweise bewegt das Gatter den Faserstrang bei einer Aufbringung des Zusatzstoffs oszillierend, wodurch die Faserstränge über ihren gesamten Umfang beschichtet werden können.advantageously, if the gate moves the fiber strand in an application of the additive oscillating, causing the fiber strands over their entire circumference can be coated.
In einer weiteren Ausgestaltung der Erfindung ist ein erstes Führungselement vorgesehen, das den Faserstrang nach einer Aufbringung des Zusatzstoffs führt. Die Führung bewirkt eine gezielte Orientierung des Faserstrangs auf seinem Weg zur Faserstrangzuführung der Extrudervorrichtung.In Another embodiment of the invention is a first guide element provided that the fiber strand after application of the additive leads. The leadership causes a targeted orientation of the fiber strand on its way for fiber strand feed the extruder device.
Ferner wird vorgeschlagen, dass zumindest ein zweites Führungselement vorgesehen ist, das den Faserstrang nach einem ersten Führungselement weiterführt und das den Zusatzstoff in den Faserstrang einarbeitet. Somit wird neben der Führung des Faserstrangs auf seinem Weg konstruktiv einfach eine Verstärkung der Vorimprägnierung erreicht.Further it is proposed that at least a second guide element is provided, which continues the fiber strand after a first guide element and which incorporates the additive into the fiber strand. Thus, next to the leadership of Fiber strand on its way constructively simply reinforcing the pre-impregnation reached.
