ABSTRACT:
The method for spacing the folds of a folded filter media assembly includes the steps of separating the folds of the filter media by the use of the tapered assembly comb having uniformly spaced teeth and subsequently inserting a rigid divider into the separated and spaced media folds to produce a uniformly spaced filter media. The comb can be discarded after the divider is inserted, and, accordingly, the comb is made of an inexpensive material having a desired degree of rigidity for handling, e.g., cardboard. The uniformly spaced filter media assembly is inserted into an operative position for filtering, e.g., as an air filter.
