<p>The belt (1), made with a series of transverse V-section ribs (6) and reinforced by cables (5) e.g. of 0.9 - 1 mm diameter, has a dynamic modulus of elongation of between 7000 and 10000 N at 120 degrees C after 2 hours, and between 8000 and 9500 N after 24 hours. It has a positive over-tension and a relaxation of over -25 per cent.</p> |
