Abstract
A conveyor for transporting articles includes an upper surface for transporting the articles and a top guide that is resiliently supported relative to the upper surface for preventing the articles from tipping over as they are transported. A plurality of resilient supporting mechanisms, such as gas springs, is provided on each of the opposite sides of the conveyor. A mechanism is provided to selectively move the top guide toward the upper surface of the conveyor against the urging of the gas springs to position the top guide at a predetermined distance relative to the upper surface of the conveyor. The mechanism includes a plurality of flexible cables having first ends that are connected to the top guide and second ends that are connected to a pair of actuating members that are supported on the conveyor for sliding movement. An actuator is provided for selectively effecting movement of the first and second actuating members and, therefore, positioning the top guide at a predetermined distance relative to the upper surface of the conveyor.
