| 摘要 |
The present invention proposes the sheeting over from a distance of a surface belonging to a vehicle, a sports pitch or any other surface requiring a protection or the removal of the sheet. The canvas sheet is rolled up on a bar by the unwinding of a reel, this rotation is combined with a simultaneous translation due to the mechanical locking of the opposite width of the canvas sheet, while a slowing-down device consisting of a ring applied on the axis of this bar in an antagonistic manner ensures that the latter rotates and is kept parallel. <IMAGE>
