Abstract

Przedmiotem zgłoszenia jest sposób zmniejszania gęstości papieru w trakcie jego wytwarzania w maszynie papierniczej, który polega na tym, że formowaną wstęgę papieru po wyjściu z pras, przed procesem jej suszenia lub w trakcie suszenia nadmuchuje się strugami powietrza o temperaturze 20-700°C wypływającymi z prędkością nie mniejszą niż 150 m/s z dysz o średnicach otworów wylotowych nie większych niż 0,5 mm, usytuowanych w odległości od powierzchni wstęgi papieru nie większej niż 25 mm.The subject of the application is a method of reducing the density of paper during its production in a paper machine, which consists in the fact that the formed paper web after being released from the presses, before its drying process or during drying is blown with air streams at a temperature of 20-700 ° C flowing from speed not less than 150 m / s with nozzles with outlet diameters not greater than 0.5 mm, located at a distance from the surface of the paper web not greater than 25 mm.
