| 摘要 |
An insulating apparatus is disclosed for thermally insulating a dryer head journalled in a dryer section of a papermaking machine. The apparatus includes a stationary insulator having a disc-shaped configuration. The insulator defines a central bore for the rotatable reception therein of the journal. A peripheral seal extends circumferentially around the insulator for inhibiting the flow of convection currents past the periphery of the insulator thereby reducing thermal losses through the head. |
