摘要： Method and apparatus in the head box of a paper machine for controlling the distortion of fibre orientation in the paper web comprise an arrangement wherein by-pass flows of pulp suspension are passed through opposite passages lateral of the turbulence generator preceding the slice portion or discharge channel of the head box. The magnitude and/or the mutual relationship of the by-pass flows is adjusted to control the distortion of the fibre orientation in that the by-pass flows produce a transverse flow in the discharge flow of the pulp suspension from the head box, the speed of which compensates for the distortion of the fibre orientation.

摘要： A movement compensator apparatus and method for compensating for movements taking place during tilting of a headbox of a paper machine and preventing transfer of strains from a pulp supply pipe in the headbox to a stationary pulp supply pipe. The movement compensator has a first pipe connected to the supply pipe by a connecting flange that permits rotation of the first pipe and the supply pipe relative to one another, and a second pipe connected to the first pipe by another connecting flange that permits rotation of the first pipe and the second pipe relative to one another. The second pipe is further connected to the stationary supply pipe by a third connecting flange that also permits rotation of the second pipe and the stationary supply pipe relative to one another.

摘要： A system for combining a dilution flow with the stock flow passed from the inlet header of the headbox of a paper/board machine. The equipment comprises a valve which regulates the dilution flow and which consists of a valve housing, of a spindle, and of a flow duct placed in the spindle, which flow duct can be rotated into different regulation positions for the purpose of regulating the dilution flow departing from the valve. One end opening of the flow duct and the flow opening in the valve housing are placed in alignment with one another irrespective of the position of rotation of the spindle. The position of the other end opening of the duct placed in the spindle in relation to the flow opening in the valve housing can be regulated by rotating the spindle.

摘要： A method and device in the regulation of the headbox of a paper machine/board machine, in which additional flows are introduced into the pulp suspension at different points across the width of the headbox. The concentration of the additional flows is different than the average concentration of the pulp suspension. The additional flows are introduced through additional-flow pipes to the vicinity of inlet openings of turbulence tubes of a turbulence generator. The grammage profile of the web in the direction of width of the web is regulated in the headbox by adjusting the distance of the end of the additional-flow pipe/pipes from the turbulence generator, whereby the amount of the additional flow entering into the additional-flow pipes and, at the same time, the amount of the pulp suspension flow are regulated.

摘要： Method and apparatus for regulating pressure in a wedge-shaped space between the wall of the headbox lip beam or the like and the breast roll. An arrangement is provided by which air jets are directed in a direction opposite to the direction in which the forming wire moves on the breast roll to eject air out of the wedge-shaped space to maintain the pressure induced therein at a desired level. The apparatus includes a blow box coupled to a source of pressurized air and the box having a wall in opposed relationship to the forming wire in which nozzle openings or slots are formed through which the air jets are directed. The blow box has a wider side which substantially closes the wedge-shaped space. Water jets are directed into the wedge-shaped space by water supply devices provided on the blow box for cleaning purposes.
