である。[Means for Solving the Problems] This invention solves the above-mentioned drawbacks. Specifically, when manufacturing a decorative board in which a synthetic resin end decorative body is integrally formed on the end portion of a wooden substrate, A soft synthetic resin mold for forming a synthetic resin end decorative body was covered from the side, and pressing materials were applied to the top and bottom of the synthetic resin mold that was in contact with the top and bottom surfaces of the substrate, and pressed from above and below. The present invention relates to a method for manufacturing a decorative laminate, which comprises injecting a resin into a synthetic resin mold and curing it in a state in which the resin is injected into the synthetic resin mold, and then removing the synthetic resin mold.

面には滑りどめ用の凹凸が設けられている。FIG. 1 is a perspective view of a stair tread board 1 before it is covered with a synthetic resin mold 2. The board 1 is made of a particle board 3 with decorative plywood 4 pasted with a veneer of precious wood adhered to both sides. A protrusion 5 is formed on the edge. The synthetic resin mold 2 has a cavity 6 for forming the nosing of the stair tread, and a substrate l.
A hollow space 7 is provided at the front edge of the
After fitting the front edge of the substrate 1 into this space 7, pressing material 8 is applied to both the upper and lower surfaces of the synthetic resin mold 2 and pressed with a press, and the synthetic resin injection provided in the synthetic resin mold 2 is pressed. A synthetic resin is injected through the hole 9 at a pressure of 1 to 1 kg/cm2 for several seconds to several minutes. As the synthetic resin, a room temperature curable urethane resin is generally used. The synthetic resin mold is removed 1 to 30 minutes after the injection, but at that time, since the synthetic resin mold 2 is made of a soft material, the synthetic resin mold is expanded vertically and forcefully removed. FIG. 2 is a side cross-sectional view of a stair tread manufactured according to the present invention, and numeral 10 indicates a nosing portion of the stair tread integrally molded with the base plate 1. FIG. The thickness T of the tip of the step nosing lO is slightly thicker than the thickness t of the substrate 1, and its surface is provided with irregularities to prevent slipping.
