Title (EN) ARRANGEMENT IN A TWO-BELT CONVEYOR
(FR) AGENCEMENT POUR UNE TRANSPORTEUSE A DEUX BANDES
Abstract:
(EN) 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.
(FR) Les deux bandes (1, 2) d'une transporteuse à deux bandes sont scellées le long d'une partie d'une course de mouvement sans fin sur chaque bord longitudinal de la transporteuse, au moyen de deux parties de bordure longitudinale (3, 5; 4, 6) de la bande en contact l'une avec l'autre. Chaque partie de bordure (3, 5; 4, 6) de la bande est munie au niveau de son bord longitudinal d'un élément absorbant la force transversale (15, 18) et s'étendant le long de toute la longueur de la bande à partir d'une partie adjacente de la bande correspondante (1, 2). Un premier groupe de plusieurs éléments à force transversale (7, 8; 11, 12) sont montés le long de la partie scellée en contact avec les éléments absorbant la force transversale (15, 18), permettant ainsi l'application d'une force compressive (P) sur les deux parties de bordure (3, 5; 4, 6) de chaque bord longitudinal de la bande, lesquelles sont en contact l'une avec l'autre. Un second groupe de plusieurs éléments à force transversale (9, 10; 13, 14) sont également montés le long de la partie scellée qui est en contact avec lesdits éléments absorbant la force transversale (15-18), permettant ainsi de tenir éloignés les deux bords longitudinaux de la transporteuse sous l'action du matériau transporté entre les courroies (1, 2). Les éléments absorbant la force transversale (15-18) absorbent également les forces de traction dans la réaction longitudinale des bandes (1, 2). En outre, les deux parties de bordure (3, 5; 4, 6) de la bande sont courbées au niveau de chaque bord longitudinal à partir du plan central (M) de la transporteuse à bandes.
