| description | The present invention relates to a method for manufacturing a pleated filter (1) obtained by pleating a filtering material and folding the pleated filtering material to form a cylindrical configuration, which method further comprises applying at least one layer of fibrous covering on the outer surface of ridges of the pleats, which fibrous covering comprising melt-blown fibres (3) of thermoplastic polymer, wherein the pleated filter (1) is arranged in parallel to the blowing head which blows the molten polymer forming fibres, whereas at the same time the filter (1) performs rotational movements and/or reciprocating motions, while the distance of the blowing head from the said outer surface of the filter (1) is selected so that the fibres blown from the head from the said outer surface of the filter (1) is selected so that the fibres blown from the blowing head at the time of contacting the pleat ridges are still in a plastic state. The application provides further a pleated filter containing a pleated filtering material folded to form preferably a cylindrical configuration, on the outer surface of which filter the covering layer manufactured according to die method of the invention is arranged. |
