| 摘要 |
The invention concerns a method for spreading a textile sheet (2) comprising at least warp yarns, wherein: the sheet (2) is made to pass between at least two rotary rollers (5), (6), of which the axes (A) extend parallel to one another and substantially perpendicular to the direction of travel of the sheet; the sheet is made to pass under pressure between at least one pressure generator (Si) of the rollers which are driven so as to oscillate axially and in phase opposition. According to the invention, at least one pressure generator of the rollers (5), (6) is produced with adjustable pressure values along the generator (G1) in order to spread the sheet (2) with a low degree of thickness variability. The invention also concerns a machine suitable for performing this method. |
