Abstract

Process and its corresponding mold for the manufacture of cushions, mattresses, pillows and the like in latex foam rubber or analogous spongy material, having an inner core of different density to that of the external part, preferably expanded polyurethane, said core being completely surrounded of the foam rubber mass, or analogous spongy material, in a well-defined spatial position with respect to it, characterized the process by comprising the following operations: A) pouring about half the amount of unvulcanized latex foam rubber or polyurethane still unexpanded into a mold into the mold; B) fixing in the space the inner core of material of density different from that of the external part by means of a plurality of organs having axial longitudinal symmetry, whose longitudinal axes, when the mold is closed, are all parallel to the plane of the bottom and of the lid of the mold and preferably equidistant from both planes; C) pouring the other half of the amount of unvulcanized latex foam rubber into the mold; D) close the mold and proceed to the vulcanization of the latex foam rubber or to the polymerization and expansion of the synthetic foam.
