Abstract
A method and apparatus for assembling oil filter components is disclosed. The components include a spring guide element which centers a filter element when assembled within a filter canister. Invention is based on the discovery that when the spring guide element is pushed horizontally into the canister by the filter element, the leading edge of the spring guide element automatically slides up the dome shaped bottom of the canister to its proper upright position without need for manual (individual) handling. An assembly machine is also disclosed which provides feed chutes for supplying the canisters, spring guide elements, and filter elements to troughs on a conveyor belt. A stationary bar cam is provided for effecting a force vector in a direction which pushes the filter element and, in turn, the spring guide element into the canister. Alternate embodiments are also disclosed wherein the components may be assembled by centrifugal force, gravity or direct plunger action.
