ABSTRACT:
Apparatus utilized in the continuous manufacture of sheet material, such as paper, includes a frame having at least one hollow beam for carrying means such as sheet-gauging heads operatively associated with the sheet material being fabricated. Thermal stability of the at least one hollow beam is enhanced by circulating fluid within the beam. Fluid displacement means which may be in the form of a series of inserts disposed end-to-end within the hollow beam define with the interior wall of the beam a fluid conduction channel. The fluid displacement means may also include generally helically oriented guides projecting into the fluid conduction channel for inducing turbulence in the circulating fluid.
