Abstract
The present disclosure provides workpiece feed systems, methods and assemblies comprising one or more tapered feed rolls positioned at an angle to incoming workpieces. The tapered feed rolls may pull individual workpieces toward a guide while gradually accelerating the workpieces and altering their direction of travel. The angle and speed of rotation of the tapered feed rolls may be automatically adjusted to control workpiece speed/acceleration, providing improved gap control and minimizing collisions between successive workpieces. Tapered feed rolls may therefore reduce or eliminate the need for a conventional bridge to decelerate the workpieces after the directional change, reducing the operational space required by a workpiece feed system.
