Abstract
PURPOSE:To make an angle of bend correct and the flatness after assembling favorable by a method wherein holes are interruptedly, formed at the bottom part of a groove, which forms a score, along the long direction of the groove. CONSTITUTION:A score 1 is provided as a groove 11, which is formed on the surface of a plastic sheet 2 so as to easily bend the sheet. Interrupted holes 3 are made at the bottom part of the groove 11 along the longitudinal direction of the bottom part. The interrupted holes 3 scatter sand uniformize the strains, which develop in the groove 11 by bending the sheet, in the long direction of the groove, so as to prevent local stress concentration and shape restoration by spring-back from occurring. The groove 11 and the interrupted holes 3 are simultaneously made by pinching a plastic sheet between a scoring blade 4, on which unevenness 42 obtained by notching a blade point 41 intermittently is produced, and a flat cradle 5.
