Abstract
651,916. Air filters. TISSUE PAPERS, Ltd., and SCHECHNER, P. June 15, 1948, No. 16124. [Class 8(ii)] A suction cleaner filter bag comprises an impervious tubular envelope 16, Fig. 2, having one end as an inlet and the other as outlet for filtered air and an edge filter 17 consisting of a plug of spirally wound or zig-zagged crepe paper strip creped transversely to the length of the strip located in the envelope so as to leave a dust collecting space between the inlet end and the plug 17. The envelope 16 which may be of transparent plastic material is sealed to the periphery of a wood or cardboard ring 15 in turn secured to a cardboard inlet tube 14. In a modification the ring 15 is dispensed with and the margin of the inlet end of the envelope 16 is folded over to form a reinforcing ring of several layers to fit over an inlet tube. In a further modification the envelope 16 has a radial flange formed by a cardboard ring to which the envelope is sealed. Alternatively the margin of the open end of the envelope is folded in several layers to form a reinforcing ring which is clamped between a flange 19, Fig. 8, and an end cap 20 of the suction cleaner.
