<P>PROBLEM TO BE SOLVED: To produce a foamed, laminated polyolefin based resin sheet which has a good appearance and a smooth surface by improving a cooling process in extrusion lamination foaming in which a foamed polyolefin based resin layer and a non-foamed polyolefin based resin layer containing a filler are laminated. <P>SOLUTION: In a method for producing a foamed, laminated sheet in which a polyolefin based resin (A) which contains a foaming gas and forms a foamed layer through extrusion molding and a polyolefin based resin (B) which contains the filler and forms a non-foamed layer through the extrusion molding are melt-kneaded and laminated, and a sheet-like material extruded from a molding die outlet is cooled by a cooling roll group, a first cooling roll and a second cooling roll are linked/driven through belt driving, and a third cooling roll is driven through belt driving. <P>COPYRIGHT: (C)2011,JPO&INPIT |
