ABSTRACT:
A method of making the combination of a power transmission belt that is to be operated in an endless path and a tensioner for the belt is provided, the tensioner comprising a support unit fixed relatively to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a biasing unit operatively associated with the support unit and the belt engaging unit urging the belt engaging unit relative to the support unit in a belt tensioning direction against the belt with a force to tension the belt, and a control unit operatively associated with the biasing unit to progressively decrease its urging force on the belt engaging unit as the speed of movement of the belt progressively increases from a certain low speed of movement thereof to a certain high speed of movement thereof.
