摘要： A plant is provided for manufacture of latex foam products comprising recesses, such as mattresses, cushions and the like. The plant makes use of a plurality of carriers placed in a ring-like configuration limited by a first, upper stretch between a foam injecting station and a product-removing station and by a second lower stretch for the return of the carriers devoid of foam, to the injecting station. At any moment the first stretch is filled with carriers, touching each other and making a single mold on which foam is injected, while on the second stretch, at least one carrier, or a discrete number of carriers, considerably separated form one another, travel. The carriers of the first and second stretch are moved by different and independent operating systems and the speed of the carriers in the second stretch is considerably higher than the speed of the carriers in the first stretch, so that, a carrier can always be present at the injecting station, while another carrier leaves the removing station.
