ABSTRACT:
A control mechanism for a lip of a headbox slice. A first vessel contains a substantially incompressible liquid. The temperature of the incompressible liquid can be varied. An expansible member communicates with the first vessel and is also full of a substantially incompressible liquid. Thus increasing the temperature of the incompressible liquid in the first vessel expands liquid from the first vessel towards the expansible member to expand that member.
