摘要 |
A tubular synthetic-resin body usable as a roadway marker comprises spaced upper and lower tubular parts interconnected by thin webs formed integrally with the upper and lower parts. A middle part of contrasting color lies between these upper and lower parts and has grooves receiving the connecting webs. Such a roadway marker is made by fitting the middle part over a core of a mold, and then injecting synthetic-resin material into the mold around this sleeve so as to form the upper and lower parts and the web. |
