A device is disclosed for making a seal (1) on a baffle (2) of a rotatable mould-holding table (3) of a thermoforming apparatus, wherein a flexible seal element is constituted by a U-shaped membrane (7) body having a first end (71) fixed to a frame and a second movable end (72) connected to a piston of a pneumatic cylinder (5), driving which causes sliding of the loop of the U-shaped body that comes into sealing contact against an edge of the baffle. |
