11 Adjustable guide rail apparatus for independently adjusting positions of guide rails disposed respectively on opposite sides of a path of a conveyor, for guiding articles. The apparatus comprises first and second elongated members to be disposed respectively in parallel and along outward surfaces of the guide rails, each member being provided with threaded sections along its length; first and second supports for supporting respectively the members in parallel to and along the outward surfaces, each support including several bodies, each body having a first channel providing a passage to and supporting the corresponding elongated member, each support having certain of their bodies provided with a second channel that is transversal and adjacent to the corresponding first channel; and rods respectively associated with certain bodies, each rod having an end that can be fixed onto the corresponding guide rail, and a threaded portion along its length. The rods are inserted into the corresponding second channel so that each rod can slide along the corresponding second channel and so that its threaded portion can be engaged with the threaded section of the corresponding elongated member, whereby a user can independently adjust the guide rails by rotating the elongated members, and lock the guide rails in desired positions with locking devices.
