Abstract

A headbox for machines for making fibrous sheet, especially paper or cardboard, in which the fluid feed lines open (preferably directly) into the top, bottom and/or front of the upstream part of the intermediate compartment, which is also sub-divided by flow dividers across the machine width so as to form a first (upstream) intermediate compartment with flow channels. A headbox (1) for a machine for the production of fibrous sheet, especially paper or cardboard, with at least one distributor (2) for distributing a pulp suspension (3) over the width of the machine (MB), a guiding device (4) with numerous channels (5), another guiding device (6) with channels (7), an intermediate compartment (8) between, a headbox nozzle (9) connected to (6) and provided with an outlet gap (10) delivering a stream of pulp suspension (11), and several feed lines (12) for a fluid to be added (13), which are distributed over MB. The fluid feed lines (12) preferably open directly into the top, bottom and/or front of the upstream part (14) of compartment (8), which is also sub-divided over at least part of its length by several flow dividers (15) spread over the machine width (MB) and forming flow channels (16) so as to form at least one first (upstream) intermediate compartment (17). An independent claim is also included for a machine for the production of fibrous sheet, especially paper and/or cardboard, with a headbox (1) as described.
