<p><P>PROBLEM TO BE SOLVED: To provide a roll receiver for supporting a roll with a plastic film, a sheet, a cloth or the like being wound around a core, formed of a lightweight, easy-to-handle and inexpensive polystyrene foam, and having a load resistance performance superior to a roll receiver formed of a polystyrene foam obtained by the bead method. <P>SOLUTION: The roll receiver formed of a styrene resin foam board manufactured by an extrusion foaming method demonstrates the superior load resistance performance when it is used with its direction parallel to the extrusion direction in the extrusion foaming method being set to the direction for supporting the roll load. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
