Rolling wheel method: Put a core in the tube, and push the outer circumference with a roller for round edge processing.

Bulging method: one is to place rubber in the tube and compress it with a punch above to make the tube protrude into shape; the other method is hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid to bulge the tube into the desired shape. Most of the production of bellows uses this method.
