FIELD: textile, paper.
SUBSTANCE: movable support surface with waterproof areas is passed through a bath with a fibre-containing solution, thus aiding in accumulation of fibres on the movable support surface. A belt is fed to the movable support surface, which contains open parts and linking parts so that open parts are substantially opposite to waterproof areas of the movable support surface. The belt is fed to the movable surface in the bath under its free surface in the area, where fibres have already been accumulated on the movable support surface, accumulation of fibres continues so that they are accumulated on linking parts and along the contour of open parts. At the same time waterproof areas do not protrude relative to the specified movable surface or protrude by not more than the thickness of a sealing substance applied onto the movable surface at the level of waterproof areas.
EFFECT: method ensures development of a fibre base with windows on a movable support surface, which does not contain relief elements, to simplify technology of base manufacturing with windows and to reduce requirements to accuracy of belt synchronisation with the surface.
