Abstract
Method for manufacturing a dry textile preform, including: pulling a textile fabric sheet; grabbing a first side portion of the sheet between rollers, the rollers forming a first flange of the first side portion of the sheet inclined at a predeterminable angle to the plane of extension of the sheet; grabbing a second side portion of the sheet opposite to the first side portion between other rollers, the other rollers forming a second flange of the second side portion of the sheet inclined at a predeterminable angle to the plane of extension of the sheet; adjusting a difference between the rolling speed of the pair of first rollers and the rolling speed of the pair of second rollers to form a curvature radius of the sheet; and adjusting distance between the rollers perpendicular to the movement direction of the sheet to form a web portion between the first flange.
