ABSTRACT:
A method of manufacturing a cushion material by welding under heat a first layer to an adjoining second layer at necessary portions of the latter by use of a welding member having a plurality of pressure applying projections. The material of the second layer is deformed and molten and flows at temperatures higher than those of the material of the first layer. In the method, the surface portions of the first layer not engaged by the welding member and lying closer to the welding member and/or the welding member itself are cooled by cooling gas thereby welding the first layer to the second layer without giving rise to any appreciable thermal change on the surface of the first layer except the portions engaged by the welding member.
