ABSTRACT:
A roll-up cover system includes a tarpaulin (30) having a fixed edge (30-1) and a free edge (30-2) secured to a winding shaft (31), in which the tarpaulin is of the double-membrane inflatable type (30a, 30b) and all or part of the unwinding of the tarpaulin is carried out by inflating the tarpaulin, the inflating pressure occurring in the tarpaulin unwinding the tarpaulin or contributing to the unwinding force. The roll-up cover system has particular application to horticultural greenhouses.
