Abstract
A system for reducing looseness and backlash generally associated with transfer feed press feed systems that includes a driven tensioning device that exerts continuous tension on the drive system to ensure positive, slip-free meshing of the drive components. The tensioning device includes a tensioning sprocket that is coupled to a sprocket of the driven system by a chain or the like. An actuator positions the tensioning sprocket to maintain tension on the chain, and, therefore, the drive system. An additional tensioning device, such as a spring-biased sprocket, is also positioned against the chain to prevent any looseness from developing during operation.
