ABSTRACT:
A tensioner for a power transmission belt which is adapted to be operated in an endless path and method of making same are provided and the tensioner comprises a rotatable idler pulley, a supporting assembly for rotatably supporting the pulley and urging same against the belt with a particular belt tensioning force with the assembly supported adjacent the belt, and a system for holding the assembly with the pulley urged against the belt, and wherein the holding system operates to lock the assembly at a fixed position immediately prior to moving the belt in its endless path and while the supporting assembly is applying the particular belt tensioning force to thereby determine a fixed center about which the pulley is rotated and the holding system operates to provide release of the assembly from the fixed position and hence the pulley from the fixed center only when the belt is stationary.
