Abstract
The low speed continuous run feature of a double facer machine is attained by a discrete drive motor coupled thereto by an overrunning clutch. The main drive shaft is coupled to the double facer machine by a fluid operated clutch coupled to circuitry for the double facer machine belt tensioner so that the double facer machine may not operate unless the belt has been tensioned.
