Abstract
PURPOSE: To produce moldings having excellent properties by stretching a heat- softened resin sheet as held by a clamping means and holding the stretched resin sheet on a mold by means of vacuum suction, thus preventing any drooping of the working resin sheet.
CONSTITUTION: A PP resin sheet 1 being held by a clamping means 2 is heated by a heater 3. As soon as the resin sheet 1 is softened, it is re-held by a secondary clamp 4 which is provided beside the clamp 2, and then subjected to stretch by moving the secondary clamp 4 toward outside by means of an air cylinder. Thereupon, the stretched sheet 1 is drawn to and held on a mold 5 by vacuum suction from inside, to form a shape or shapes as desired. According to this method, any deflection of the working resin sheet 1 that may occur following the heat-softening treatment can be prevented, resulting in the performance of satisfactory molding.
