Abstract
A method for producing and vulcanizing an inflatable hollow body from a double cloth having upper and lower plies with edges and pile yarns spacing the plies apart includes applying a respective gas-tight unvulcanized layer of rubber to each of the upper and lower piles of the double cloth. The edges of the upper and lower plies are joined with angle braces forming a hollow body. The hollow body is evacuated over a predetermined period of time and the hollow body is vulcanized in the evacuated state.
