[0002] Composite board is a commonly used board at present. There are many types of composite boards, but its basic structure is an upper metal plate, a lower metal plate and a core plate. The core plate has many different functions, such as a honeycomb core layer, a three-dimensional core layer, an A2 fireproof core layer and a B1 fireproof core layer. Therefore, a variety of composite boards are derived, such as honeycomb core composite boards, three-dimensional core composite boards, A2 composite boards and B1 composite boards. However, each composite board currently requires a separate production line for production, which greatly increases the equipment investment cost. Summary of the invention

[0062] A slide 9 that can slide laterally is arranged downstream of the first laminating machine 5.
