Abstract
In a multi spindle drive belt tensioning assembly a motor is mounted to a frame and the drive pulley is coupled for rotation to the motor shaft. At least two driven pulleys are each coupled to a driven member rotatably mounted to the frame. The driven pulleys are spaced apart relative to one another and at least one belt is in engagement with the drive pulley and each of the driven pulleys. In either pulley is rotatably coupled to the frame between two of the driven pulleys and engageable with the belt. The idler pulley is movable relative to the belt to increase or decrease the tension thereof and the degree of engagement between the belt and the driven pulleys. The idler pulley is adjustable relative to the belt to allow a desired belt tension in engagement between the belt and the driven pulleys such that the belt extends approximately 180 degrees around the circumference defined by each of the driven pulleys.
