Abstract

The invention relates to a control system for the head box in a paper-making machine/cardboard machine, by means of which the grammage of the web can be adjusted to the desired value. According to the invention a functional device 20 is used, which is designed to operate functional elements, which adjust the grammage of the web in various positions over the width of the head box, such as dilution valves V1 ... Vn or a leader strip. In one embodiment of the control system according to the invention a functional device, which is designed to move in the lateral direction of the head box, is therefore designed to engage as required with spindles that control the leader strip in the discharge funnel of the head box. A plurality of spindles can thereby be operated by one functional device. The grammage of the web is controlled by controlling the position of the leader strip. According to the invention the grammage can also be controlled through the supply of dilution liquid, advantageously the dilution water for the pulp suspension. <IMAGE>
