Abstract

PURPOSE: To obtain a deeply drawn molding free of cracking, breaking, wrinkling or the like by inserting a multi-directional fiber plywood made up of more than two layers of veneers glued at such an angle that individual fibers are neither perpendicular nor parallel to each other in the direction into a tapered section of a lower die and press it with an upper die through a cushion material.
CONSTITUTION: For example, three layers of veneers are laminated through an adhesive with fibers arranged in the directions of the arrows a, b and c shifted by 120° from each other to obtain a multi-directional fiber plywood 4, which is inserted into a tapered section 3B of a lower die 3 and softened by curing under evaporation. Then, after a cushion material 5 is placed on the plywood 4, an upper die 2 is lowered to heat it under pressure. Thus, a deeply drawn molding such as tray is obtained. Under a condition that the plywood 4 is inserted in the tapered section 3B, there is no angle causing a hitching resistance thereby preventing cracking. In addition, interposition of the cushion material 5 permits the material to be pressed entirely thereby assuring a deeply drawn molding free of cracking, breakihg, wrinkling, irregularities or the like.
