ABSTRACT:
An apparatus for molding a continuous foamed plastic element, such as a floor element having a substantially parallelepipedic central body and at least one side lug, includes a mold in which respective molding cavities of the central body and of the side lug are defined between a bottom wall, a pair of opposite side walls and a cover. A mechanism adjustably positions at least one of the cover and one or both of the side walls of the mold, away from and towards the bottom wall, to regulate, in an adjustable and substantially continuous manner, the height of the molding cavities for at least one of the central body and the at least one side lug of the continuous element.
