摘要

The lip at the outlet of the nozzle duct is adjustable via an adjusting mechanism which includes a longitudinal adjusting rod disposed parallel to the pivot axis of the lip and a number of connecting rods pivotally connected at each respective end to the adjusting rod and the lip. Axial movement of the adjusting rod causes the lip to move relative to a permeable element on a suction roll. The movement of the lip is carried out in a curvilinear relation with respect to the axial movement of the adjusting rod.
