Abstract

A filter comprises a section of pleated filter fabric 2 clamped between detachable frame members 3, 4, profiled to maintain the pleated shape. The fabric is replaced when clogged. Fig. 1 shows rectangular frame members with rods 7, 8 round which the fabric 2 is extended. In manufacture the fabric 2 is drawn from a roll and held at one end while rods 8 are successively lowered to form successive pleats (Fig. 2). Rods 8 may extend between two levers pivoted to frame member 3 (Fig. 3) to facilitate this process. In Figs. 6-8 a preformed frusto-conical pleated filter paper sleeve is removably clamped between end fittings, each composing inner and outer rings with matching sets of teeth. <IMAGE>
