PURPOSE:To form strobe stripes with a fixed width by forming wide projection parts for the strobe stripes, applying a coat for antireflection to the projection parts and then striping off the coat having the width narrower than that of said projection part. CONSTITUTION:The projection parts 3 for strobe stripes with comparatively wide width (b) are formed on a turntable 1 and coat for antireflection is applied to the projection parts 3. The turntable 1 is turned while catching its periphery and drilled with a drill. A shaft is inserted into the drilled hole to be used as a revolving shaft 4, and while turning the turntable 1, a tool having the width (a) narrower than the width (b) is abutted to each projection part 3 to strip off the surface of the coat by the width (a), so that strobe stripes 2 are formed. After applying the antireflection coat, the strobe stripes with a fixed width can be obtained simply only by one cutting work. |
