Abstract

A paper filter (4) is placed in a casing (2) and a cover (3) placed on the casing to pre-form a filter cartridge (1). The filter cartridge is then spun as putty (resin) is fed into the filter. The putty is ejected by centrifugal force onto the periphery of the filter, along the internal wall of the metal casing. The filter continues to rotate throughout polymerisation of the putty. A paper filter (4) is placed in a casing (2) and a cover (3) placed on the casing to pre-form a filter cartridge (1). The filter cartridge is then spun as putty (resin) is fed into the filter. The putty is ejected by centrifugal force onto the periphery of the filter, along the internal wall of the metal casing. The filter continues to rotate throughout polymerisation of the putty. The cover has an opening (5) for the air inlet and the putty is put into the filter using this opening. A means of ejection (6) is placed on the route F1 of the putty flow before the filter and the putty flows on this means. The rotation of the filter cartridge ensures that the putty is spread over its periphery by centrifugal force. The paper filter has a means of protection combined with the means of ejection. The putty is a mono- component and the polymerisation is carried out by heating. Alternatively, the putty is bi-composite and is polymerized at ambient temperature. AN Independent claim is included for a filter cartridge made using the above process.
