Abstract

A control for the headbox slice opening of a papermaking machine in which the slice is position controlled by pneumatic means, such that the load upon the slice lips is transferred to a heavy frame member. Air blocks are mounted between the slice lip and the heavy frame member to allow precise position control of the slice lips.
