Abstract

The invention refers to a headbox device for feeding a pulp suspension to a dewatering installation, particularly for a tissue machine. It is mainly characterized by an eccentric shaft being provided to set the slice gap between a minimum and a maximum height. It also includes a wedge shaped steel lamella tip attached under pre-stress by a tie/rod to a headbox partition.
