Abstract
A process for producing a filter with multiple folds from an aqueous fiber mixture that is applied to a porous form, in which a paper-like filter mat is produced on the form under the action of pressure, and it is carried out without mechanical deformation of the rough casting. This is achieved pursuant to the invention by the fact that the aqueous fiber mixture is deposited on the porous form having the contour of the filter, from loading chambers separate from one another, and the filter is built up of adjacent fold sections in layers on the form by separate introduction of the fiber mixture to the fold sections connected to one another.
