ABSTRACT:
A filter element for use in a filter for pressurized material in flowable form is disclosed. The filter element includes an elongated perforate web adapted to move longitudinally across the flow axis of the material being filtered and to accommodate filtered flow therethrough of the material. A plurality of seal members are fixed to the perforate web transversely to and at spaced intervals along the longitudinal axis thereof. The perforate web extends continuously and uninterruptedly across the seal members to thereby provide the sole and exclusive means of interconnection therebetween. The seal members preferably have a thickness at least as great or greater than the thickness of the perforate web, and preferably the ends of the seal members protrude laterally beyond the side edges of the perforate web.
