Thermally compensated coater rod

摘要

A coater for applying a coating medium to a moving surface includes a mounting; a coater rod bed connected to the mounting; and a coater rod carried by the coater rod bed. The coater rod is configured for applying the coating medium to the moving surface, and includes a hollow rod with a longitudinal bore interconnecting opposite ends thereof. A pair of fluid couplings are respectively attached to each end of the coater rod. Each fluid coupling has an internal fluid passage which is disposed in fluid communication with the longitudinal bore of the coater rod, whereby a thermal transfer fluid may be transported through the longitudinal bore of the coater rod.
