Abstract
The joining device comprises two halves of a joining device made up of a flexible and elastic material each one comprising a pair of flexible wings (4). These wings are fixed to the conveyor belt (6) by rivets (10). A frame (5) extends into the wings (4) and in the part of the joining device which constitutes the joining itself. The frame (5) is trimmed to washers (10) or to small plates (8) used as reinforcement for the fixing holes. A linking stem is threaded across through holes or passages provided in the linking elements.
Claims14
A joining device for a conveyor belt, said device having linking elements each having an internal surface defining a hollow part, said linking elements being aligned on the external edge of two half joining devices, each joining device of said joining devices being solidly linked to a respective end of the conveyor belt, said linking elements being arranged to receive a linking stem which is passed transversely and alternatively through a linking element of said linking elements belonging to one of said half joining devices, then through a linking element of said linking elements belonging to another of said half joining devices, and so on, the half joining devices being brought close to each other in order to overlap the linking elements on each said joining device, said joining device being formed from a flexible and elastic material comprising an internal frame or reinforcement designed for surrounding over approximately 180.degree. of the hollow part of the linking elements used as a passage for the linking stems at a distance from the surface of the linking elements or flush with said surface, said joining device having flexible fastening arms in which the reinforcement extends,
- wherein the flexibility and the elasticity of the internal frame or reinforcement is in the same range as those of said material.
The joining device according to 3, wherein the trimming of cables is achieved by forming loops which partially surround the washers or the sockets lining the holes.
