Abstract

A belt end body includes an arrangement for coupling together with a further corresponding belt end body. The belt end body further includes a plurality of clamping openings and clamping recesses for accommodating reinforcement members of a belt in a clamped manner. The coupling arrangement and the clamping openings lie substantially opposite each other when viewed in the longitudinal direction of the belt end body. The belt end body is configured in such a way that the unclamped segments of the clamped reinforcement members are always in the neutral phase during operation.

First claim

What is claimed is:

1. A belt end body assembly of a conveyor belt configured to roll on a cylindrical body of a belt conveyor installation, the belt end body assembly comprising:
a belt segment having a plurality of reinforcement members embedded in elastomer having respective end portions extending from said elastomer and being free of said elastomer;
a belt end body defining a longitudinal direction and having first and second longitudinal ends;
said first longitudinal end having projections for coupling said belt end body to a further, corresponding belt end body;
said belt end body defining a plane extending in said longitudinal direction and having a plurality of clamping openings formed in said second end thereof and clamping recesses extending into said belt end body from corresponding ones of said clamping openings for receiving respective ones of said end portions of said reinforcement members therein;
each of said end portions having an innermost segment clamped in said clamping recess and an outermost segment disposed in the region of said clamping openings;
said belt end body defining a longitudinal direction and said projections and said clamping openings lying substantially opposite each other when viewed in said longitudinal direction;
said belt end body having a surface for contact engaging said cylindrical body during movement of the conveyor belt;
said surface having a curved depression formed therein to facilitate movement over said cylindrical body; and,
each of said clamping openings having a widening so as to permit the unclamped outermost segment of the end portion corresponding thereto to move perpendicularly to said plane so as to always remain in a neutral phase as said conveyor belt moves over drums in said conveyor installation thereby preventing kinking of said end portions.

2. The belt end body assembly of claim 1 , wherein said cylindrical body has a radius (R); and, said curved depression has a radius essentially corresponding to said radius (R) of said cylindrical body.

3. The belt end body assembly of claim 1 , wherein said widening of said at least one clamping opening is configured to have a hyperbolic form.

4. The belt end body assembly of claim 1 , wherein said projections are configured as a hinge.

5. The belt end body assembly of claim 1 , wherein said projections are configured so as to be detachable.

6. The belt end body assembly of claim 1 , wherein said belt end body is configured to have a form that is entirely integrated into the cross section of said belt.

7. The belt end body assembly of claim 1 , wherein each of said clamping openings defines a channel extending into said belt end body to transition into the clamping recess corresponding thereto with the diameter of said channel being greater than the diameter of the clamping recess.

8. The belt end body assembly of claim 7 , wherein said channel has a hyperbolic shape when viewed in section taken along said longitudinal direction.

9. A belt assembly configured to roll on a cylindrical body of a belt conveyor installation, the belt assembly comprising:
a belt defining a longitudinal direction (A) and being made of elastomer;
said belt having a plurality of mutually parallel reinforcement members embedded in said elastomer and running in said longitudinal direction (A);
said reinforcement members having respective end portions extending from said elastomer and being free of elastomer;
a belt end body extending in said longitudinal direction (A) and having first and second longitudinal ends;
said first longitudinal end having projections for coupling said belt end body to a further, corresponding belt end body;
said belt end body defining a plane extending in said longitudinal direction and having a plurality of clamping openings formed in said second end thereof and clamping recesses extending into said body from corresponding ones of said clamping openings for receiving respective ones of said end portions of said reinforcement members therein;
each of said end portions having an innermost segment clamped in said clamping recess and an outermost segment disposed in the region of said clamping openings;
said projections and said clamping openings lying substantially opposite each other when viewed in said longitudinal direction (A);
said belt end body having a surface for contact engaging said cylindrical body during movement of the conveyor belt;
said surface having a curved depression formed therein to facilitate movement over said cylindrical body; and,
each of said clamping openings having a widening so as to permit the unclamped outermost segment of the end portion corresponding thereto to move perpendicularly to said plane so as to always remain in a neutral phase as said belt assembly moves over drums in said belt conveyor installation thereby preventing kinking of said end portions.
