Abstract

A device for feeding a pulp suspension to a tissue machine includes a headbox having top and bottom lips defining a slice gap forming a free flow jet of the pulp suspension. The device also includes at least one eccentric shaft for setting the slice gap between a minimum and a maximum height. Each eccentric shaft is supported at several points over the machine width and is driven directly by a gear motor.
