<p>#CMT# #/CMT# The head box has a manifold battery (9) whose manifolds (11) are provided with throttling bushes. Each bush is partially inserted into an interior of one manifold at an end of a distributor (10) of the manifold. A part of the bushes is asymmetrically designed and rotatable around a bush longitudinal axis. Pressure loss of a fiber suspension flow is regulatable during turning of the flow into the manifold by rotating the bushes around a longitudinal axis of the manifold. Each bush has an asymmetrical inlet section whose curvature and/or taper are formed asymmetric to the bush longitudinal axis. #CMT#USE : #/CMT# Hydraulic head box for a fiber web manufacturing machine. #CMT#ADVANTAGE : #/CMT# The pressure loss of the fiber suspension flow is regulatable during turning of the suspension flow into the manifold by rotating the throttling bushes around the longitudinal axis of the manifold, thus improving regulation of the fiber suspension flow in an easy and flexible manner, and manufacturing paper with constant and good quality. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side sectional view of a hydraulic head box. 9 : Manifold battery 10 : Distributor 11 : Manifolds 12 : Nozzle area 13 : Distributor plate.</p> |
