Document Type and Number:

WIPO Patent Application WO/2018/225490

Kind Code:

A1

Abstract:

The present invention mainly addresses the problem of making it possible to reduce protrusion of a foaming layer at a switching portion between a self-seal part and a nipping seal part. The present invention pertains to a foam molding method for sealing core material (4) and skin material (5) at a seal part (7) and molding a foaming layer (6) inside the seal part (7). A part of the seal part (7) is used as a self-seal part (23) in which an edge part (22) of the skin material (5) is accommodated in a concave part (21) provided in the core material (4), and the remaining part of the seal part (7) is used as a nipping seal part (26) in which the core material (4) and the edge part (25) of the skin material (5) are nipped by foam molding molds (11, 12). A switching part (27) between the nipping seal part (26) and the self-seal part (23) is used as a crimping seal part (29) for crimping the edge part (28) of the skin material (5) onto the core material (4).
