Abstract
An improved belt guide system has individual guide sleeves mounted on one or more of the guide rolls, one sleeve for each belt, in an agricultural round baler. Each sleeve encircles the roll surface of the guide roll and is positioned between the belt and the guide roll surface in a manner allowing relative rotational movement between the sleeve and the guide roll. Each guide sleeve is thus allowed to match the peripheral speed of the respective belt as it passes over the guide roll and allow slippage to occur between the guide roll surface and the inner circumference of the guide sleeve. Flanges extending radially outwardly on each sleeve end maintain the sleeve alignment with the respective belt.
