2. Description of the Related Art The above-described laminating method is used when a laminate of a required number of films, sheets, plate-like materials, non-woven fabrics, woven fabrics, knits, papers or prepregs is formed by a molding machine or processed by a processing machine. It is necessary to first carry the material into a molding machine or processing machine. When the molding and processing are completed, the laminate is taken out from a molding machine or a processing machine. Therefore, conventionally, a large number of these laminates are manually carried in or carried out.

[0003]

When a molding machine, a processing machine, or the like becomes large, it is necessary to carry in and carry out a laminate to a high position, but these operations involve difficulties. When the treatment is performed at a high temperature or a high pressure, there is a possibility that danger is involved.
