Title (EN) LATERALLY FLEXIBLE CONVEYOR BELT
(FR) BANDE TRANSPORTEUSE FLEXIBLE LATERALEMENT
Abstract: front page image
(EN)The structure of a conveyor belt supportable on throughing rollers for conveying bulk material. The belt is capable of sharp lateral curves and includes a main body section with an embedded, central, inextensible flexible spine formed of cables (12). Corrugations (14), (16) extend outwardly to the edges from the central section of the body. The central section of the body is rectangular in cross section and constitutes the majority of the belt. The belt is molded flat and has layers of cords or strands (20), (22) of inextensible material such as wire, embedded therein from edge to edge. The layers are parallel to each other and to the surfaces of the belt adjacent the edges and adjacent the central portion of the body. Along the lines where the corrugations meet the central portion, the layers are positioned closer together to thereby define hinges (44), (46) for bending of the belt longitudinally to solve the problem of the throughing of the belt during the conveying of bulk material.
(FR)Structure d"une bande transporteuse supportee sur des cylindres a rigole pour transporter du materiau en vrac. La bande peut faire des courbes laterales prononcees et comprend un corps principal avec un dos noye central, flexible, inextensible, forme de cables (12). Des ondulations (14, 16) s"etendent vers l"exterieur des bords de la partie centrale du corps. La partie centrale du corps possede une section rectangulaire et constitue la partie principale de la bande. La bande est coulee, en forme plate et possede des couches de cordes ou torons (20, 22) en materiaux inextensibles tels que des cables noyes a l"interieur bord a bord. Les couches sont paralleles les unes au autres et aux surfaces de la bande adjacente aux bords et adjacentes a la partie centrale du corps. Le long des lignes ou les ondulations rencontrent la partie centrale, les couches sont positionnees plus pres les unes des autres pour definir ainsi des charnieres (44, 46) de courbure de la bande longitudinalement pour resoudre le probleme des rigoles de la bande pendant le transport du materiau en vrac.
