Abstract

A system (100) is disclosed for producing a frame (91) for air filtering means (90) comprising at least one mould (40) adapted to retain a filter element (80) and delivery means (31 ) adapted to deliver an extinguishable plastic material into the mould (40) so as to form a peripheral frame (91) of extinguishable plastic material around said filter element (80). A method is also disclosed for obtaining said frame (91) for the air filtering means (90).
