METHOD FOR MANUFACTURING A FILTER FROM SHEET METAL AND A FILTER MANUFACTURED BY THE METHOD

摘要

A method for manufacturing a filter from sheet metal uses two perforated sheets mounted at a distance from one another, between which is formed a space for a filtered liquid. In the method, on at least one edge of one of the sheets is formed a connecting groove by bending an edge of the sheet. In the connecting groove is placed a connecting part, of either a separate edge strip or of the opposite sheet, in such a way that the said connecting part can be moved to a correct location in the connecting groove, after which the connecting part is connected to the connecting groove by welding.
