где Vc - скорость движения формующей сетки;
Vф - скорость фильтрации воздуха через слой формуемого полотна и сетку с помощью отсасывающего средства, при установившемся стационарном потоке воздуха из аэровзвеси в отсасывающее средство;
η коэффициент трения скольжения волокон о формующую сетку.A method of forming a web of aerosuspension of fibrous material, comprising supplying an aerosuspension to a moving forming mesh mounted obliquely to the flow of the aerosuspension, and removing the air component of the air suspension using suction means mounted on the back of the mesh, characterized in that the angle α of inclination of the forming mesh in its direction movement to the direction of flow of air suspension is selected from the ratio:
where V c is the speed of movement of the forming mesh;
V f - the rate of air filtration through the layer of the molded web and the mesh using the suction means, with a steady-state stationary flow of air from the air suspension into the suction means;
η the coefficient of friction of the sliding of the fibers on the forming mesh.
