Abstract A variable pleat filter paper pleator with rotary scoring means is disclosed. A large roll of resin impregnated paper is passed through rotary scoring means to score the paper to facilitate folding (pleating). The paper is drawn past or through the rotary scoring means by drive rollers. The rotary scoring means rotational speed may be varied with respect to the drive Tolls. The scored paper passes from the drive rolls into pleating means which causes the paper to form pleats. The pleated paper is passed through an oven to cure the paper. The cured or partially cured paper is placed in porous canisters. Lids are sealed on each end of the canister to form an air filter for vehicles.
