This paper deals with effects to the gluing strength of hot-press plywoods by pressures (Tab. 1,A), times of pressing (Tab. 1,B), and temperatures of gluing (Tab. 1,C) when plywoods are joined with blood-clot glue.The plywoods were made by the method of three-way layout having 3 factors at 3 levels each : Pressures [A_1 (10 kg/cm^2) ・ A_2 (20 kg/cm^2) ・ A_3 (20 kg/cm^2)], times of pressing [B_1 (min.) ・ B_2 (10 min.) ・ B_3 (15 min.)], and temperatures of gluing [C_1(100℃) ・ C_2(115℃) ・C_3(130℃)].These experiments were replicated 3 times.Then the analytical research of the data, the gluing strengths of hot-pressed plywoods, was done by analysis variance.The results obtained as follows.1. The higher pressure is added, the stronger gluing strength of plywoods may be obtained.2. The time of pressing does not much influence upon the gluing strengths of plywoods.3. The more the temperatures of gluing is in creased, the stronger gluing strengths of plywoods may be obtained.4. It seems there are interactions between the temperatures of gluing and pressures.
