Abstract:
The purpose of the present invention is to provide a laminate shaped to have fine irregularities using a general-purpose soft polyurethane foam without using a soft polyurethane foam having a special configuration. A soft polyurethane foam and a flexible surface member are laminated via a moisture-curing hot-melt adhesive. By curing the moisture-curing hot-melt adhesive, the soft polyurethane foam and the surface member are laminated and integrated with each other to form a laminate for shaping irregularities. The laminate for shaping irregularities is heated and compressed by a heating compression device having irregularities on a pressing surface thereof to shape irregularities on a surface of the laminate for shaping irregularities.
