<p>The two belts (1, 2) of a two-belt conveyor are sealed along a part of an endless path of motion at each longitudinal edge of the conveyor by means of two longitudinal belt edge portions (3, 5; 4, 6) contacting one another. Each belt edge portion (3, 5; 4, 6) is provided at each longitudinal edge with a transverse force-absorbing element (15-18) extending along the entire length of the belt and projecting from an adjacent part of the respective belt (1, 2). A plurality of first transverse force members (7, 8; 11, 12) are mounted along the sealed portion in contact with the transverse force-absorbing elements (15-18) for applying a compressive force (P) to the two belt edge portions (3, 5; 4, 6) of each longitudinal edge which are in contact with one another. A plurality of second transverse force members (9, 10; 13, 14) are also mounted along the sealed part in contact with said transverse force-absorbing elements (15-18) for keeping apart the two longitudinal edges of the conveyor against the action of the material conveyed between the belts (1, 2). The transverse force-absorbing elements (15-18) also absorb tensile forces in the longitudinal reaction of the belts (1, 2). Furthermore, the two belt edge portions (3, 5; 4, 6) are bent out at each longitudinal edge from the center plane (M) of the belt conveyor.</p> |
