In case of using flat plate plastic in various fields such as home appliance field, building field, and automobile interior, warping or deflection occurs due to the action of tensile force and compressive force and gravity. Since it is difficult to maintain the original shape of the flat plate plastic according to the external stress and the load of the plastic itself, it is generally used by adopting zinc or chromium plated steel reinforcement.

However, the steel reinforcing material has a problem in that it is troublesome to carry out auxiliary operations such as cutting work.

Such an apparatus has an advantage that a lightweight sheet having a high strength can be produced by extruding long fiber glass fiber and continuous fiber.

However, in the manufacturing apparatus as described above, it is required that continuous fibers are arranged at regular intervals so as to be supplied so that the strength of the produced reinforcing material is uniform throughout.

In addition, the above-described production apparatus has a problem that the continuous fibers are simply passed through the thermoplastic resin melted portion to cause the resin to be hardened, and the infiltration rate is low.
