Abstract
A method form forming fluted filtration media is provided. The method includes forming fluted filtration media having a repeating pattern of flutes wherein at least one flute in the repeating pattern of flutes comprises at least one ridge in a flute period between adjacent same side peaks. The repeating pattern of flutes can comprise at least one flute having at least two ridges provided in a flute period between adjacent same side peaks. An apparatus for forming fluted filtration media is provided.
Claims22
A method for forming fluted filtration media comprising:
- fluting filtration media to provide fluted filtration media having a repeating pattern of flutes wherein the repeating pattern of flutes comprises at least one flute having at least one ridge provided in a flute period between adjacent same side peaks;
- and
- providing a facing sheet of filtration media;
- applying an adhesive bead to at least one end of the fluted filtration media such that fluid flowing through the flute is directed through the fluted filtration media;
- at least a portion of the adhesive bead formed between the fluted filtration media and the facing sheet of the filtration media;
- wherein the method comprises feeding the filtration media into a bite formed between a first roll and a second roll to form the fluted filtration media;
- and
- wherein the first roll comprises a plurality of first roll projections and a plurality of first roll recesses, and wherein at least one of the first roll projections comprises at least two media contact areas separated by a media relaxation area.
A method for forming fluted filtration media comprising:
- fluting filtration media to provide fluted filtration media having a repeating pattern of flutes wherein the repeating pattern of flutes comprises at least one flute having at least one ridge provided in a flute period between adjacent same side peaks;
- combining the fluted filtration media with a facing sheet to provide a section of single facer media;
- applying an adhesive bead to at least one end of the fluted filtration media between a portion of the facer media and fluted filtration media such that fluid flowing through the flute must exit the flute through the filtration media;
- and
- layering multiple sections of single facer media;
- wherein the flutes are arranged substantially parallel to one another on the multiple sections of single facer media;
- wherein the method comprises feeding the filtration media into a bite formed between a first roll and a second roll to form the fluted filtration media.
