Abstract

Apparatus for manufacturing a flexible cylinder, in which a preformed flexible cylinder wound on itself is placed within a forming cavity, characterized in that a means is provided for applying pressure radially outward along the interior of said cylinder preformed flexible for said preformed flexible cylinder to unroll and be applied under pressure against the inner wall of said formation cavity, said device including a mandrel consisting of an inflatable cylindrical balloon located within said formation cavity, and means for inflating said Balloon-shaped mandrel sufficiently for said balloon-shaped mandrel to expand radially outwardly against the inner surface of said preformed flexible cylinder.
