ABSTRACT:
A web manufacturing apparatus including a flexible shaping member that engages fluid material of which a web is formed, a support that extends parallel to the shaping member and a plurality of thermal expansion rods that extend between the shaping member and the support so that the shaping member can be flexed to control the web thickness profile by means of heaters on the thermal expansion rod. Each thermal expansion rod is fixed to the shaping member and is secured to the support via a differential screw mechanism that includes a driven screw and an adjusting screw positioned in tandem in a threaded bore through the support and are coupled so that the driven screw can be turned by turning the adjusting screw. The driven and adjusting screws have internally threaded bores and one end of the thermal expansion rod screws into the bore of the driven screw. A jam screw is screwed into the bore of the adjusting screw to be screwed down against the end of the thermal expansion rod within the differential screw mechanism.
