Method and machine for spreading a fabric-type textile sheet |
| 摘要 |
A method for spreading a textile sheet where the sheet is caused to run between at least two rotary rollers, the axes of which extend parallel to each other and substantially perpendicular to the running direction of sheet. The sheet under pressure is caused to pass between at least one pressure generator of the rollers driven into axial oscillation and in phase opposition. At least one pressure generator of the rollers has adjustable pressure values along the generator in order to spread the sheet with a low thickness variability. |

1. A method for spreading a textile sheet including at least warp yarns, said method comprising the steps of:
passing a textile sheet that includes at least warp yarns between at least two rollers, the axes of which extend parallel to one another and substantially perpendicular to the direction of travel of the textile sheet; and applying pressure to the textile sheet by using at least one pressure generator to apply pressure to one of the rollers and driving the two rollers into axial oscillation and in phase opposition, wherein at least one of said pressure generators has adjustable pressure values for spreading the textile sheet to form a spread textile sheet having a low thickness variability. |
