<p>PURPOSE:To eliminate a loss in rubber materials and the occurence of condemned articles to enhance the production rate of intermittent type rubber rollers, by arranging a plurality of rubber cylinders on a metal core coated with an unhardened rubber at predetermined intervals, and then by hardening the unhardened rubber to make the rubber cylinders adhere to the metal core. CONSTITUTION:A cold hardening type rubber is beforehand formed in a cylindrical shape, and is cut, after it has been hardened, into a plurality of short rubber cylinders 2 having a predetermined length. Meanwhile, a metal core 1 is coated with a primer, and then is coated with an unhardened rubber of the same material as that of the above-mentioned rubber. After the plurality of rubber cylinders 2 are set on the metal core 1 at predetermined intervals, these rubber cylinders 2 are made adhere to the metal core 1 by hardening the unhardened rubber. With this process, a loss in rubber materials and the occurrence of condemned articles may be eliminated.</p> |
