    Patent number: 5829577
    Abstract: A method of retrofitting the idler assemblies of an idler conveyor with an air plenum is shown. The method includes the steps of detaching the belt and removing a preselected number of idler assemblies from an existing frame of the idler conveyor. A number of bracket pairs are attached to the frame and an air plenum is attached to the brackets. An air source is attached to the plenum and the belt is reattached. An air plenum conveyor is also shown which includes a frame with a number of bracket pairs attached at spaced intervals along the frame. A V-shaped plenum is secured to the brackets. An air source is attached to the plenum to permit a continuous belt positioned about the plenum to be support by the plenum.
