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.
Claims23
Apparatus for molding a continuous foamed plastic element comprising:
- a) a mold including:
- i) a bottom wall, a pair of opposite side walls and a cover;
- and
- ii) a molding seat, having a shape mating that of said element, defined in said mold between said side walls, said bottom wall and said cover;
- b) means for displacing said cover and said side walls of the mold towards and away from said bottom wall to longitudinally close and respectively open said mold;
- and
- c) first means for positioning in an adjustable, manner, said cover away from and towards said bottom wall of the mold to control in an adjustable and substantially continuous manners the height of the molding seat.
Apparatus for molding a continuous foamed plastic element comprising a substantially parallelepipedic central body and at least one lateral lug laterally and longitudinally extending from said central body, said apparatus including:
- a) a mold, wherein a molding seat having a shape mating that of said element is defined, comprising:
- i) a bottom wall, a pair of opposed side walls and a cover;
- ii) a first molding cavity for the central body of said element, defined in said seat between said side walls, said bottom wall and said cover;
- and
- iii) a second molding cavity for said at least one lug of said element, defined in said seat between a groove formed in at least one of said side walls and said bottom wall;
- b) means for displacing said cover and said side walls of the mold towards and away from said bottom wall to longitudinally close and respectively open said mold;
- and
- c) means for positioning, in an adjustable manners said at least one side wall away from and towards said bottom wall of the mold to controls in an adjustable and substantially continuous manner, the height of said second molding cavity.
Apparatus for molding a continuous foamed plastic element comprising a substantially parallelepipedic central body and at least one side lug laterally and longitudinally extending from said central body, said apparatus including:
- a) a mold, wherein a molding seat having a shape mating that of said element is defined, comprising:
- i) a bottom wall, a pair of opposed side walls and a cover;
- ii) a first molding cavity for the central body of said element, defined in said seat between said side walls, said bottom wall and said cover;
- iii) a second molding cavity for said at least one lug of said element defined in said seat between a groove formed in at least one of said side walls and said bottom wall;
- b) means for displacing said cover and said side walls of the mold towards and away from said bottom wall to longitudinally close and respectively open said mold;
- c) first and second means for respectively, independently and adjustably positioning said cover and said at least one side wall away from and towards said bottom wall of the mold to control in an adjustable and substantially continuous manner, the height of said first and, respectively, said second molding cavities.
