Title: LAYING HEAD AND DEVICE AND METHOD FOR CONSTRUCTING A THREE-DIMENSIONAL PREFORM FOR A COMPONENT MADE OF A FIBRE COMPOSITE
Abstract:
The invention relates to a laying head for producing fibre rovings and component preforms from fibres, comprising an inlet (20e), which is adapted for inserting a plurality of dry rovings (33; R1, R2 etc.), a fibre conveying device (20f) for conveying rovings (33; R1, R2 etc.) introduced through the inlet (20e) in a fibre infeed direction (V), simultaneously and independently of one another, an outlet (20a), which is arranged in the fibre infeed direction (V) downstream of the fibre conveying device (20f), and which is adapted for the simultaneous laying of a plurality of rovings (33; R1, R2 etc.) on a workpiece carrier (40) for constructing a three-dimensional preform (31), a fibre cutting device (21, 21i, 21j), which is arranged in the fibre infeed direction (V) downstream of the fibre conveying device (20f) and upstream of the outlet (20a) and is adapted for cutting the rovings (33; R1, R2 etc.), and a nozzle (22, 22i, 22j) for attaching a medium to the rovings (33; R1, R2 etc.), wherein the nozzle (22, 22i, 22j) is adapted for applying the medium to two sides of the rovings (33; R1, R2 etc.) and for introducing the medium into the rovings (33; R1, R2 etc.).
