in the direction of the filter chamber 29 the inlet ducts 17 may be either of single part or multi part configuration it is likewise possible for the inlet ducts 17 to be formed with a circular cross section fig1 clearly shows an inlet duct 17 running between the support flange 36 and the distributor flange 37 the figure also shows the protective lip 22 which is pivotably mounted on the lower end of the support flange 36 by a hinge 23 fig1 shows the lower end of the support ring 19 or of the support flange 36 the lower end of the support ring 19 is adjoined by the hinge 23 which is formed as a film hinge the hinge 23 is realized by a thinned material portion the hinge 23 is adjoined in turn by a carrier skirt 38 which is likewise composed of rubber here the carrier skirt 38 the hinge 23 and the end of the support ring 19 are formed from the same material in the exemplary embodiment this is rubber the flexurally rigid lip tab 39 is fixed to the carrier skirt 38 the flexurally rigid lip tab 39 is composed of suitably rigid material for example steel or plastic the flexurally rigid lip tab 39 may u2014 as in the exemplary embodiment u2014 be adhesively bonded to the carrier skirt 38 it is also possible for the carrier skirt 38 and the lip tab 39 to be of integrated design using a two component material it is also possible for the carrier skirt 38 and lip tab 39 to be clipped or screwed or welded to one another fig1 shows by way of example a filter panel with a centrally arranged pulp inlet 9 fig1 shows.
