Patent

CA 2621833

A flapper roll including a resilient substantially cylindrical core and extending radially outwardly therefrom a spaced array of resilient rearwardly cantilevered curved flapper flanges lying in a plane substantially containing a direction of flow of workpieces passing under the roll. The flanges are rearwardly curved relative to a direction of rotation of the roll about a corresponding axis of rotation. The axis is orthogonal to the plane. Each flange may be substantially flat across its width in a direction parallel to said axis so as to substantially evenly distribute across the width a resiliently biased downward force applied to the workpieces passing under the roll. Each flange is compressed as it engages the top surface of its corresponding workpiece to thereby substantially evenly hold down the workpiece and stabilize the workpiece directionally along its intended flow path.
