Abstract
Apparatus and a method is disclosed herein whereby flexible drive members such as for example conventional V-belts may be automatically prestretched and tensioned to a particular predetermined value with both a high degree of reliability and repeatablity. The apparatus comprises a sensor for continuously monitoring the actual tension on the flexible member and providing a signal to a central control unit. A force generating apparatus is also interconnected with the central control unit and operates to exert a force such as to increase or decrease the tension to which the flexible member is subjected. Wrench means may also be provided which are connected to the central control unit and actuated thereby so as to lock the movable pulley member or the like in position once the predetermined tension has been achieved on the flexible interconnecting member.
