PROBLEM TO BE SOLVED: To obtain a compressed foam by retaining a molding comprising a closed cell resin molding having shape recovery properties in a compressed state at least in one direction, excellent in handleability, capable of being filled simply and densely even in a narrow space. SOLUTION: This compressed molding is obtained by retaining a molding comprising a closed cell resin molding having shape recovery properties in a compressed state at least in one direction. The closed cell ratio of the closed cell resin foam is preferably 60-100%. For example, a sheet, a tube, etc., may be cited as the shape of the molding. The resin constituting the molding has preferably <=10% compression set. To be concrete, an olefin resin, a styrene- based resin, etc., may be cited as the resin. The objective foam 5, for example, is obtained by laying a long molding 1 composed of a closed cell resin molding between a compressing roll 2 and a direction changing roll 31 at the end of an endless belt 3 made of a metal, compressing the molding and continuously rolling the compressed molding on a wrapping roll 4 while pressing it to the wrapping roll 4 side by the endless belt 3. |
