A forked frame 2 is pivoted about the gimbal axis 3 of pulley 4. Frame 2 supports a conical pressure roller 6 that rides against the upper surface 5 of pulley 4 (note the mounting method to avoid rubbing). Also supported by frame 2 is arm 7 that carries the belt-follower roller 8. The position of arm 7 relative to frame 2 is defined by adjustment screw 9; spring 10 provides sufficient force to assure contact between screw 9 and frame 2 at all times.
