- at least one first endless conveyor (6) extending between drive rollers and deviation rollers (12),
- at least one second endless conveyor (14) situated in a position overlying said first conveyor, said second conveyor extending between drive rollers (16) and deviation rollers (20),
- a curved surface (26) positioned at the exit end of the first (6) and second (14) endless conveyor with its cavity facing the conveyors, to convey the roller shutter (30) leaving the upper surface of the first conveyor, with its slats (32 ) having their cavity facing upwards, onto the upper surface of the overlying conveyor such that they are disposed with their cavity facing downwards,
- monodirectional passage means (28) for guiding the roller shutter leaving the first conveyor such that it rests on the second conveyor.
