ABSTRACT:
A pulp feed for a paper making machine comprising a nozzle channel or duct for the flow of the pulp or the like and terminating at a movable permeable element. The pulp feed has a first section bounded by a lower lip closer to the permeable element and a more remotely located pivotable upper lip which is adjustable at its edge which is downstream with regard to the flow of the pulp. The pulp feed further includes a second section which is bounded, on the one hand, by the permeable element, and on the other hand, by a pre-lip which merges with the upper lip and is pivotably mounted thereat by means of at least one substantially plug-shaped part. The outlet end of the pre-lip is adjustable in relation to the permeable element. The plug-shaped part is only rotatably mounted at least at two locations which are removed from one another and at the remaining bearing locations the bearing means possesses a displaceability with play in a plane containing an appreciable component in the direction of the surfaces of the upper lip and the pre-lip, respectively, bounding the nozzle channel or duct.
