초록 ▼

An air filter comprising a sheet of filter material folded in a zig-zag configuration. A hardenable material is dispensed in a flowable state onto the sheet. The hardenable material has a varying thickness such that upon hardening, it holds the folds of the sheet apart in a selected orientation. The hardenable material may comprise glue to also secure the folds together. An air penetrable sheet can be secured to the fold edges at one or both sides of the filter.

대표청구항 ▼

A filter comprised of sheet material having first and second opposing sides, said sheet folded in a zig-zag configuration such that said first and second sides of said sheet form first and second sets of spaced-apart channels, each channel having an open wide end and a closed narrow end formed by mutually convergent channel faces such that a width of each channel becomes progressively smaller toward said narrow end, said first set of channels having their channel faces convergent in a first direction, and said second set of channels having their channel faces convergent in a second direction opposite said first direction, and spacer means for maintaining said convergent relationship of said channel faces, said spacer means comprising a hardenable material dispensed in a flowable state onto at least said first side of said sheet so as to lie within said first set of channels when said sheet is in a folded state, with some of said hardenable material being disposed adjacent said narrow ends of said first set of channels and some of said hardenable material being disposed adjacent said wide ends of said first set of channels, said hardenable material disposed adjacent said wide ends having a greater thickness than said hardenable material disposed adjacent said narrow ends when said filter is in said folded state, to maintain said convergent relationship of said channel faces, said thickness being measured in the direction of said channel width, wherein said hardenable material is dispensed onto both of said faces adjacent said wide end of each channel of said first set of channels and onto only one of said faces adjacent said narrow end of each channel of said first set of channels.
