A conditioning apparatus for a rotating annular belt at a powder reinforcing machine, wherein an arrangement of arms are pivotably secured to a frame portion of the machine, to scrape the belt as it intermittently rotates, to deposit a release fluid onto the width of the belt as it rotates, and to spread the fluid evenly across the belt if fluid puddles up thereon due to the intermittent nature of the belts rotation. The arm for releasing fluid onto the belt has a felt portion which receives fluid from a conduit in communication with a reservoir for the fluid. All the arms are pivotably attached to the frame portion of the machine, adjacent the annular belt, and all are lockable in an upright position to facilitate repair or replacement of any components thereof.
