输送辊及输送辊的制造方法
摘要：
本发明提供一种能够在高温环境下以合适的状态输送卷筒料的输送辊。输送辊1具有：圆筒状的中空辊基部2，形成于中空辊基部2的外周面上的圆筒状的缓冲部3，以及形成于缓冲部的外周面上的镀层部4。缓冲部3的热膨胀系数α3大于等于镀层部4的热膨胀系数α4、α5。由于输送辊1即使在高温环境下，与卷筒料接触的镀层部4的表面也能够维持平滑，因此能够以合适的状态输送卷筒料W。
摘要（英）：

The invention provides a transfer roller capable of transferring drums in a proper state at high temperature. A transfer roller (1) has a cylindrical hollow roller base portion (2), a cylindrical buffer portion (3) formed on the peripheral surface of the hollow roller base portion (2), and a plating coat portion (4) formed on the peripheral surface of the buffer portion. The coefficient of thermal expansion [alpha]3 of the buffer portion is larger than or equal to the coefficient of thermal expansion [alpha]4 and 5 of the plating coat portion (4). Because the surface of the plating coat portion (4), contacting with drums, of transfer roller (1) can be kept smooth at high temperature, the transfer roller can transfer drums (W) at a proper state.
