Description

DETAILED DESCRIPTION OF THE INVENTION The present invention interposes a synthetic resin foam between the front and back materials, and forms on the decorative surface of the surface material a moritalysin texture or a surface with a three-dimensional effect with larger irregularities. The present invention relates to a device for manufacturing composite boards with rich and decorative designs.

Recently, composite plates have been increasingly used due to demands for mechanical properties, strength, and versatility.

However, most of the manufacturing equipment up to now has adopted the so-called batch method, which is very inefficient.

There are various inconveniences in continuously producing composite boards with a sandwich structure with a lysine-like decorative surface.
It could not be put into practical use.

In order to eliminate such drawbacks, the present invention forms a thin metal plate into a gutter shape, and after completing the lysine process on the decorative surface of the metal sheet, a core material is supplied from the back side of the metal sheet to form a sheet-like material that will become the back surface material. Each device is arranged in a line so that the gutter-like opening is closed with a trough-like opening, and the core material is foamed and hardened by heating and pressurizing.
Moreover, the present invention provides an apparatus that can produce uniform composite plates with excellent design at low cost and in large quantities by controlling the entire body with a control device.
