Abstract

PURPOSE: To prevent damages such as cracks due to large local elongation by drawing a synthetic resin sheet having slits or notches which have been imparted with upper and lower dies while it is heated and softened.
CONSTITUTION: A synthetic resin sheet 1 with notches 2 such as slits which have been prepared is heated and softened, formed with upper and lower drawing dies and local elongation which appears in forming is absorbed. For example, notches 2 such as slits are given beforehand on a composite sheet 1 which is obtained by sticking a leather sheet 1a of polyvinyl chloride, etc. and a foam substance sheet 1b of polypropylene foam substance, etc. to each other up and down. Then, the sheet 1 is drawn, a notch 2 is located at a valley part 2' and a product is obtained by removing this valley part 2' so that the notch 2 does not appear on the product. It is preferable to give the notch 2 at a deep drawing part where large elongation is estimated.
