Abstract: Systems and methods for automated fabrication of pleated filters that promote user-selected adjustment of the pleat spacing generated by the system. A lower conveyor of a pleat spacing station is operated at a selected conveyor rate. A gathered pleated segment of filter material is received at the pleat spacing station. The pleat spacing station expands a pleat spacing of the gathered pleated segment in forming a pleated filter segment. Expansion of the pleats at the pleat spacing station is accomplished by initially engaging the filter material along the lower conveyor, with the conveyor rate being alterable by a user, including on the fly alteration, to establish a desired pleat spacing and thus pleat density in the pleated filter.

Abstract: A framed air filter and method of making. The framed air filter includes air filter media and a frame with a frame portion with an upstream flange and a downstream flange and an inner sidewall and an outer sidewall. The inner sidewall includes an open-ended, offset slot.

Abstract: A framed air filter and method of making. The framed air filter includes a non-self-supporting air filter media with a generally rectangular perimeter with four major edges, a support frame comprised of four support frame portions each portion being mounted on one of the four major edges of the non-self-supporting air filter media, and a support grill that is attached to each of the four portions of the support frame but that is not integral with any portion of the support frame.
