Process to manufacture a composite foam

摘要

Process to manufacture a composite foam comprising at least two foams with cellular structure, at least one of them being a latex foam. Present process avails itself of the steps of:
a) preparing separately the forming mixtures of said foams of cellular structure;
b) mixing independently the one from the other said forming mixtures;
c) foaming separately each of said forming mixture;
d) sending separately the foams obtained at step c) into a single mixing installation
e) mixing the foams till to manufacture the composite foam. Preferably the composite foam is deposited on a laying surface to form rest articles for example mattresses provided with recesses.
