A process for forming a web by aerodynamic method comprises feeding an aerosuspension onto a moving forming wire positioned at an inclination angle .alpha. relative to the aerosuspension flow and removing an air component of the above aerosuspension by means of a suction device located on a backside of the wire, with the incline angle .alpha. being selected by the equation arcctg(Vw/Vf + ~~) < .alpha. < arcctg(Vw/Vf - ~~), where: Vw - velocit y of forming wire; Vf - air filtration rate through a layer of formed web and wir e provided by a suction device at a steady stationary airflow from the aerosuspension into the suction device. As a result, a possible shear of the formed web caused by the aerodynamic pressure of aerosuspension flow is prevented, which permits production of paper having a high degree of uniformity.
