Abstract

PURPOSE: To obtain this roller, by easily releasing a mold only by pulling up a core bar to an upper portion of the mold without using special tools by hardening a liquefied coating material sticked on the circumference of the core bar and by thermally contracting the coating material by positioning the material in an atmosphere with low temperatures.
CONSTITUTION: Room temperature hardening type liquefied silicone rubber is injected into a mold, to which a core bar is upright arranged, from an upper portion. After a coating material is hardened, the material is admitted into a low temperature chamber with the mold, the coating material is thermally contracted by cooling it at 0W-10°C and the mold and the coating material are brought to a condition that both are perfectly separated. Then, the mold is released by pulling up the core bar to an upper portion of the mold.
EFFECT: The mold can be released without overhauling the mold.
