<p>A continuous belt (14) has upper and lower runs (14a, 14b) and is supported by upper and lower runs (23a, 23b) of steel ropes (23) carried and driven by rollers (12, 13). The ropes (23) are supported on wheels (22) carried by a frame (11). Rollers (30) invert the lower run of the belt and lead it onto the lower run of the ropes. Magnetic members (50) are secured to the belt and hold the belt relative to the ropes to inhibit relative movement and reduce wear. </p> |
