Abstract:
1. A process for making integral elastic supports comprising the step of: forming a frame of a rigid or substantially rigid material to have an outer edge; forming at least one pad element from a resilient material; associating said pad element with said frame and defining with the outer edge of the frame a common peripheral portion, such that the outer edge of the frame and an outer edge of the pad element become disposed over one another; and forming a bead from a polymeric material enveloping at least partly said common peripheral portion; wherein said step of forming said bead is carried out after said step of forming said at least one pad element and said step of associating said pad element to said frame and defining said peripheral portion, said polymeric material being a substantially waterproof material and being injected over said common peripheral portion to provide a waterproof area along said common peripheral portion and prevent any undesired infiltration in such common peripheral portion.
