Abstract:
1. A device for manufacturing a textile preform, the device comprising: a creel comprising a textile fabric sheet wound up on the creel; a pair of first rollers being configured to grab a first side portion of the fabric sheet between the first rollers and to form a first flange of the first side portion of the fabric sheet being pulled from the creel inclined at a predeterminable angle to the plane of extension of the fabric sheet; and a pair of second rollers being configured to grab a second side portion of the fabric sheet opposite to the first side portion between the second rollers and to form a second flange of the second side portion of the fabric sheet inclined at a predeterminable angle to the plane of extension of the fabric sheet, wherein the rolling speed of the pair of first rollers and the rolling speed of the pair of second rollers is adjustable to form a curvature radius of the fabric sheet, which curvature radius depends on the extent of the adjusted difference between the rolling speeds of the pairs of first and second rollers, and wherein the pair of first rollers and/or the pair of second rollers are movable along a distance vector perpendicular to the movement direction of the fabric sheet to form a web portion between the first flange and the second flange, the web portion height depending on the distance between the pairs of first and second rollers.
