PURPOSE:To realize the attractive external appearance under the condition that no break of cell due to the discharge of gas develops and further prevent the mechanical strength from lowering by a method wherein the specified thickness of a foam is pressed with a press tool having a specified press plate after the foam is heated in advance up to its formable temperature. CONSTITUTION:A press tool is formed by fixing a metallic press plate, the thickness of which is 0.2-3.0mm and which is worked into a desired shape such as rectilinear, curvilinear, circular, chain-like or the like one, to a metallic plate such as woody, aluminum or the like one, so as to be used for the pressing of a foam 1 having closed cells. The thickness, which is 50% or more, preferably 65% or more of the original thickness of the foam heated in advance upto its formable temperature with a sandwich heater or the like, is pressed with said metallic press plate so as to give the foam a press pattern having unique strong contrast by the strong and deep pressed part 2. In addition, because the resultant pressed foam can be freely bent and folded at the pressed part, unique and diverse product values are given to the foam product. |
