摘要： The apparatus (10) of the present invention is a papermaking machine with a forming fabric (12) in a looped configuration. The forming fabric (12) carries paper stock (100) through the papermaking process. The forming fabric (12) passes over a liquid-filled cavity (20) which is bounded on its lower surface by a flexible non-permeable membrane (14). A roll (22) with regular protrusions (24) underneath the membrane (14) is rotated to vertically excite the membrane (14), the liquid-filled cavity (20), and, subsequently, the paper stock (100) in order to disperse the paper stock (100) into a random orientation.

摘要： The present invention provides a method making stratified paper by redistributing the pulp suspension inside the headbox nozzle using acoustic radiation waves. Acoustic radiation forces fractionate fibers based on fiber radius. The acoustic radiation waves separate the fibers by pushing the coarse and longer fibers to the inner area while fines and smaller fibers remain in the outer area. This has a similar effect of multi-layer stratification headbox, and provides paper with a smoother surface.

摘要： A feed line (10) for supplying a suspension in the distribution system (20) of the stock flow (30) of a paper machine is provided with a supsension equalizer (40) arranged upstream from the distribution system (20) and connected thereto by means of a straight feed piece. The suspension equalizer acts as a turbulence generator, whereby it sets the suspension into a state of turbulence with such force that the suspension is homogenized and the acceleration profile of the suspension is equalled out inside the cross-section of the feed line. This also enables optimum stock flow conditions to be created directly prior to the stock flow or even with relatively long feed lines running through windings or curves in order to meet the quality requirements for paper production. In one preferred embodiment, the turbulence generator consists of a tube section that is similar in shape to a venturi tube with an abruptly reduced cross section (42), followed by a gradual expansion of said cross section (45).

摘要： Method for preventing fibre flocculations to occur and to disperse already formed fibre flocculations, better to distribute additive chemicals, to increase fibrillation, to improve reaction and yield from two component chemicals, to prevent the forming of microbiological and other types of build-ups onto machine parts and other parts of the white water circulations, to prevent the filling of wires and felts, to prevent flocculation in coating equipments, to reduce content of air in the stock, and to reduce the foaming. This is achieved by that ultrasonic energy with a frequency of 15 - 60 kHz is added to the stock, machine parts, washing trays or coaters via externally mounted ultrasonic transducers or internally applied submersible ultrasonic units. The ultrasonic energy is added preferably by means of externally onto the head box mounted ultrasonic transducers or internally applied submersible ultrasonic units. The level of ultrasonic energy is controlled by in-line installed formation or flocculation size measurement systems to arrive at desired flocculation. The measured flocculation is used as a criterium for set point optimisation of weight per unit area for the paper or the board produced, and for maximum production per unit of time.
