Adjustable wall apparatus for molding a continuous foamed plastics element

Apparatus for molding a continuous foamed plastics element of the type comprising a substantially parallelepipedic central body and at least one projection laterally and longitudinally extending from said body, said apparatus including a mold comprising:

• i) a bottom wall, a plurality of opposite side walls, and a cover;
• ii) a forming chamber and a stabilization chamber of said continuous element, said chambers being defined inside the mold between said side walls, said bottom wall and said cover;
• iii) a first molding seat of the central body of said continuous element defined within said forming and stabilization chambers of the mold;
• iv) a second molding seat of said at least one lateral projection of the continuous element defined within the forming and stabilization chambers of the mold between a groove formed in at least one of said side walls and said bottom wall;
• wherein said at least one side wall comprises a plurality of structurally independent segments means being provided for positioning in an adjustable manner each of the independent segments of said at least one side wall toward and away from the bottom wall of the mold so as to regulate in an independent, adjustable and substantially continuous manner the height of the second molding seat defined within said forming and stabilization chambers of the mold.
