Abstract
One of the junction devices for a conveyor belt comprises three parts, namely an upper part (2), a lower part (3) and an intermediate part (4). Inserts (6′) and (7′) are used to assemble parts (2) and (3) using screws (5). Inserts (6) and (7) are used to assemble the junction device on the ends of a conveyor belt.
Claims15
A non-disconnectable junction device for connecting two ends of a conveyor belt having a longitudinal direction, the junction device comprising:
- a flat upper part, a flat lower part, and an intermediate part between said upper and lower parts,
- each of said upper and lower parts being made of a flexible elastic material provided with a reinforcement, said reinforcement comprising a woven fabric that is loose in warp and in weft and that is flexible up to a defined limit in a first direction and in a second direction perpendicular to the first direction, said woven fabric having warp threads and weft threads, wherein one of said warp threads and said weft threads are arranged to form an angle with a transverse direction of the junction device, the transverse direction being perpendicular to the longitudinal direction.
A non-disconnectable junction device for connecting two ends of a conveyor belt having a longitudinal direction, the junction device comprising:
- a flat upper part, a flat lower part, and an intermediate part between said upper and lower parts,
- each of said upper and lower parts being made of a flexible elastic material provided with a reinforcement, said reinforcement comprising a textile that is flexible up to a defined limit in a first direction and in a second direction perpendicular to the first direction;
- and
- annular inserts in each of said upper and lower parts corresponding positions, each of said annular inserts having a central depressed recess that defines a hole therethrough, insides of the holes in said annular inserts in said lower part being threaded.
A method of making a junction device for connecting two ends of a conveyor belt, the method comprising the steps of:
- providing two half-molds, a lower one of the half-molds having projections from a bottom thereof;
- forming a layer of vulcanizable rubber in the lower half-mold so that the projections extend through the layer;
- placing annular inserts on the projections, each of the annular inserts having a central depressed recess that defines a hole therethrough, insides of the holes in the annular inserts being threaded;
- placing a flexible elastic material on the projections in the lower mold, the flexible elastic material having a reinforcement, the reinforcement comprising a textile that is flexible up to a defined limit in a first direction and in second direction perpendicular to the first direction;
- placing the molds together and pressurizing the joined molds so that the rubber covers the threaded insides of ti annular inserts;
- and
- removing the molded part, which constitutes a lower part of the junction device.
