Abstract
A filter cartridge has a tubular filter element made from a porous, flexible sheet forming an annular succession of pleats having axial ridges, in the form of vanes all curved in a same circumferential direction, each vane comprising an upper face and a lower face. The lower face and upper face of each vane has lines of least resistance forming hinges, enabling the curvature of the vanes to be better controlled.
