    摘要： A filter apparatus and method utilize a filter element, defining a longitudinal axis and an axial end thereof, and having a central winding structure and a length of fluted filter material wound about the winding structure with the flutes of the media oriented to provide for filtration of fluid passing axially through the filter element. An edge of filter media defines the axial end of the filter element when the media is wound about the winding structure. An axial end of the winding structure is disposed adjacent the axial end of the filter element. A winding feature extends substantially axially outward from the axial end of the winding structure to a distal end of the winding feature. The filter media is wrapped about the winding structure such that the axial end of the filter element is disposed substantially flush with the distal end of the winding feature.

    摘要： A filter element for filtering a particle-containing paint composition or a particle loading slurry composition which is a precursor to a particle-containing paint composition is provided. The filtration element comprises at least one filtration layer formed from woven polymer fibers and having substantially uniform pores and two spacer layers. The spacer layers have raised projections to create a space between adjacent spacer layers having contacting projections. The filtration element has a pleated or spirally wound configuration.

    摘要： A prefilter bag for insertion into a standard filtration bag apparatus, having a filtration assembly comprising a seamless filter membrane having uniform pore openings preselected within the range of between about 2 and about 50 microns (.mu.) and a linearly channeled, non-deformable, semi-rigid liquid transport thermoplastic sheet in the form of a molded webbing or netting in contact with the upper surface of the filter membrane; said webbing having marginal edges which are coextensive with those of the membrane; said assembly adapted to be shaped by continuous winding of the assembly upon itself for 2 to 5 complete convolutions around a tubular mandrel so as to form a cylindrical tube or cone; the bottom of said cylinder being sealed to prevent liquid leakage and the top of said cylinder, forming a liquid inlet opening, being sealed to a retaining ring adapted to be inserted in, attached to or sealed to an outer, retaining ring of a non-wrapped filter bag. The inlet of the wrapped cylindrical bag is optionally fitted with vortex directing means to enhance a linearly tangential direction of the entering liquid against the walls of the inside membrane. The invention also pertains to a method for the fabrication and use of the present filtration bag.

    摘要： A filter element for straining liquid formed of a filter material in a convoluted form including two portions, one portion being a planar portion and the other portion being a corrugated portion having a plurality of elevated areas. The filter material is foled in half in the longitudinal center and wound in convolutions so that a series of letters V are formed on a transverse cross-sectional surface thereof. The pitch of the elevated areas is smaller in the central portion of the convoluted filter element corresponding to the end of the filter material at which winding is started and larger in the outer peripheral portion thereof.
