ABSTRACT:
A smoothing device for an applicator unit for applying a coating on a moving web of fabric, or the like. A hollow supporting beam supports a doctor element via a holding device carried on the beam. A supporting body extends through the beam. An outer pipe surrounds the supporting body and is radially spaced therefrom. Hydraulic pressure elements between the outer pipe and the supporting body transmit forces to the supporting body. At circumferentially spaced locations around the outer pipe, the outer pipe engages the interior of the beam, defining liquid transmission channels located circumferentially between the connections to the support beam around the outer pipe. The channels permit liquid to be transmitted axially of the support beam for transferring heat along and eliminating localized heat stress on the beam. Various cross-sectional shapes of the outer pipe and of the beam are disclosed.
