ABSTRACT:
A conventional filter pleating machine has a laterally movable pusher bar and a vertically movable stripper bar parallel to it and normally spaced laterally from it above a table, with a vertically movable breaker bar between the other two bars and normally below the table top. The invention lies in providing the lower edges of the pusher bar and the stripper bar with a plurality of longitudinally spaced upwardly extending slots for receiving parallel separator tapes above a filter strip extending along the table beneath those two bars, and also in providing the upper edge of the breaker bar with longitudinally spaced downwardly extending slots for receiving parallel separator tapes below the filter strip when the breaker bar is raised, whereby the pleats in the filter strip will be separated by the separator tapes folded between them.
