Abstract

809,899. Suction cleaner filters. VAN DER HEEM N. V. Sept. 23, 1957 [Nov. 7, 1956], No. 29783/57. Class 8(2). A porous paper filter bag suitable for use within the casing of a cylinder-type section cleaner comprises spaced inner and outer jackets 8, 7 between which dust is collected ; one end of the outer jacket 7 having an aperture 10 in sealing engagement with the suction inlet 5 of the cleaner and the other end of jacket 8 being secured to the corresponding end of jacket 7. The air permiability of the outer jacket is less than that of the inner jacket whereby the former remains against the casing wall. An inner fabric filter bag 4 is supported on a framework and the jackets of the paper bag may be pleated.
