Patent ID: 6926781

Claim:
A method of making filtration product comprising the steps of: providing filtration media having a first face, a second face and at least one side edge surface; providing an indefinite length supply of strip framing material, said strip framing material including at least one longitudinally extending sidewall portion and an edge portion separated by a longitudinally extending living hinge; providing substantially the entire sidewall and edge portion including the living hinge with an adhesive layer; combining a length of the strip framing material along at least a portion of the side edge surface of the filtration media so as to adhere the adhesive on the sidewall portion of the strip framing material along an edge of the filtration media; bending the edge portion of the strip framing material that has been combined with the filtration media from a first orientation, wherein the edge portion extends generally in a transverse direction of the sidewall portion of the strip framing material, to a second orientation, wherein the edge portion extends more toward the filtration media than in the first orientation thereof so as to squeeze adhesive from the living hinge to form a bead of adhesive between the sidewall portion and the edge portion; securing the edge portion of the strip framing material in its second orientation; and cutting the strip framing material as combined with the filtration media from its supply of indefinite length.
