ABSTRACT:
A method of molding soft sheet material having a foam layer and a skin layer. In the method, a skin powder is sprinkled on a predetermined area of the foam layer for forming the skin layer. The predetermined area is such that when the molded product is produced, the only waste material needing to be removed is foam layer. Therefore, the method enables recycling of the waste material and provides an increased yield.
