Abstract
PURPOSE: To remove defects due to the sag of forming material by a method wherein the forming material is positioned on a contractible, elastic sheet stretched under a mold and held nearly horizontally by thd stretching force of the sheet and vacuum forming is performed in contact with a mold.
CONSTITUTION: A mold 1 for vacuum forming is arranged with its forming surface down and a sheet 3 rich in contractibity and elasticity is arranged nearly horizontally under the mold. In order to perform the vacuum forming, a heated and softened forming material (m) is mounted on the upper surface of the sheet 3, the forming material (m) is held nearly horizontally by the tensile strength of the sheet 3, the mold 1 and the sheet 3 are moved relatively and are brought into contact with each other. Even the material under the molten or excessively softened state can be treated smootly by the vacuum forming without raising problems of wrinkles and irregular thickness, etc. of a formed product caused by the sag of the material.
