Abstract: The invention relates to an apparatus for manufacturing expansion-molded articles continuously by conveying foamed beads into a heating region sandwiched between upper and lower belts. The apparatus has a belt that continuously travels along the upper inside face of a passageway, defined by structural members, whose cross-section constitutes an approximately rectangular shape and a belt that continuously travels along the lower inside face thereof. At least one of the upper and lower structural members that form the passageway is capable of movement in the vertical direction between the side-face structural members such that the thickness of the expansion-molded article can easily be varied. And at least one of the side-face structural members is capable of movement in the lateral direction between the upper and lower structural members such that the width of the expansion-molded article can easily be varied.

Abstract: The invention relates to apparatus for manufacturing expansion-molded articles capable of manufacturing expansion-molded articles continuously by conveying foamed beads into a heating region sandwiched between upper and lower belts and foaming by heating, and consists in apparatus for manufacturing expansion-molded articles constituted such that the thickness or width of the expansion-molded article can be altered.
