Summary:A curing bladder (7) for a tire has a shape exhibiting symmetry of revolution with a central axis and comprises a flexible wall made of cross-linked rubber, the external surface (20) of the wall comprising an air drainage zone (21) and an air removal zone (22) adjacent to the drainage zone, the bladder (7) being equipped with an air drainage structure comprising elements recessed into the external surface, the recessed elements forming a network of channels (30) extending in the air drainage zone (21) and as far as the air removal zone (22). The depth of a channel (30) of the network, defining the shortest path (31) connecting any point of the network of channels, which is situated in the air drainage zone (21), and the air removal zone (22), increases along the length of the path.
