Extruded profile filter framing

摘要

A framed filter media comprising a filter media having a fluid inlet face and a fluid outlet face with peripheral sidewalls. The peripheral sidewalls are attached to a strip frame by an adhesive-potting compound. The continuous strip frame is formed into three or more (up to an infinite number if the sidewall sections(s) is formed into a circular filter frame) sidewall sections having a substantially flat sidewall and at least two projecting filter retaining tabs which form a channel on a first face of the sidewall section for containing the adhesive potting compound. The sidewall sections are separated by corner notches extending through the retaining tabs at least to the substantially flat sidewalls. Two terminal sidewall sections meet to form a seam such that the sidewall sections circumscribe the filter media peripheral sidewalls. The continuous strip frame is formed by extruding a continuous strip frame blank comprising at least a substantially flat sidewall and at least two projecting filter retaining tabs forming a continuous channel on a first face of the continuous strip frame blank. The filter retaining tabs are then notched to form corner notches which corner notches extend at least to the substantially flat sidewalls creating sidewall section between the corner notches and optionally scoring first and/or second faces of the sidewall portions to form living hinges. The continuous strip frame blank is further cut into discrete strip frame blanks.
