Abstract
A machine is for the manufacture of a hollow glass article that includes at least one thin side wall. The machine includes at least one molten glass parison distributor, a blank mold including a cavity designed to successively receive at least one parison of molten glass, and components that form a blank of the article in the blank mold, transfer the blank into a cavity of the finishing mold, and form the article in the finishing mold. The cavity of the finishing mold includes at least one side part provided with a concave cavity to form, on the side wall of the article, a convex bulge directed towards the exterior of the article. The machine further includes a component that removes the bulge to give the side wall of the article a substantially constant thickness.
