Abstract
PURPOSE: To improve the fitness of a sheet to the surface of a forming die by a method wherein the heated and softened synthetic resin sheet which is gripped and supported by supporting ends at both sides is released from gripping by the supporting parts when it is drawn.
CONSTITUTION: A synthetic resin sheet 1 is heated and softened when it is gripped and supported by supporing parts 2 on both sides. Then, when this sheet 1 is drawn it is released from the combination with this supporting parts 2 and laid on the drawing die 3. The sheet 1 is fitted to the surface of the die and it follows these dies well when the dies 3 are closed. The fitness of the sheet 1 to the surface of the dies can be improved further if the width between both supporting parts 2 is reduced beforehand and the sheet 1 is sagged before it is released from gripping by the supporting parts 2.
