The invention concerns a disconnectible and reconnectible junction device for conveyor band made up of two flat flexible elements (A, a)~ presenting at the front side complementary shapes capable of interleaving in one same plane, connected rearwardly to the ends of a conveyor band, by sticking, vulcanization, riveting, clamping, thermoplastic molding, or formed directly by moulding over the ends of the conveyor band, each one of the flexible elements comprising at the front side oblong strips (L1, L2, L3, 1 1, 1 2, 1 3) in the longitudinal direction, separated by notches (E1, E2, E3, e1, e2, e3) of a shape complementary to those of the strips, the said strips comprising aligned holes (1) capable of receiving at least two and preferably several linking stems which cross through them in an approximately transversal direction, and being made of an elastomer material reinforced by one or several reinforcement layers (1) to which adheres the elastomer material, the number of junction stems and their spacing in the longitudinal direction being chosen in relation, on the one hand with the forces to be transmitted by the conveyor band and on the other hand by the adherence of the elastomer material surfaces to the reinforcement layer on reinforcement layers surfaces.

L'invention concerne un dispositif de jonctionnement déconnectable et reconnectable pour bande transporteuse constitué de deux éléments souples plats (A, a) présentant à l'avant des formes complémentaires susceptibles de s'imbriquer dans un même plan, reliés par l'arrière aux extrémités d'une bande transporteuse par collage, vulcanisation, rivetage, agrafage, soudure thermoplastique, ou formés directement sur les extrémités de la bande transporteuse par moulage, chacun des éléments souples comportant à l'avant des languettes oblongues (L1, L2, L3, 11, 12, 13) dans le sens longitudinal, séparées par des échancrures (E1, E2, E3, e1, e2, e3) de forme complémentaire de celles des languettes, lesdites languettes comportant des trous (1) alignés susceptibles de recevoir au moins deux, et de préférence plusieurs tiges de liaison les traversant dans le sens approximativement transversal, et étant constituées d'une matière élastomère armée d'une nappe, ou de plusieurs nappes d'armature (1), auxquelles adhère la matière élastomère, le nombre des tiges de jonctionnement et leur espacement dans le sens longitudinal étant choisis en fonction, d'une part, des forces à transmettre par la bande transporteuse et, d'autre part, de l'adhérence des surfaces de matière élastomère aux surfaces de la nappe d'armature, ou des nappes d'armature.
