## Abstract

A conveyor belt scraper (40) which includes a base (10) and a scraper element (42) which is molded to the base (10).

## Claims

### Claim 1

A conveyor belt scraper comprising:
a base comprising
an elongate body of uniform cross-section having a bridging piece with a first side and a second side opposed to the first side,
first and second spaced apart legs on the first side of the bridging piece; and
at least two spaced apart retention sections on the second side of the bridging piece in such that the first and second legs project from the first side and are divergent and in that the retaining formations extend from the second side, away from the legs; and
a scraper element formed by over-moulding the same onto the body and over the at least two spaced apart retention sections of the body.

### Claim 2 (depends on 1)

The conveyor belt scraper according to claim 1, wherein the at least two spaced apart retention sections comprise a first retention section, a second retention section, and a third retention section, and wherein the first retention section on the second side of the bridging piece is flanked by the second and third retention sections which are respectively spaced from the first retention section and which extend from the second side at respective opposed extremities of the bridging piece.

### Claim 3 (depends on 2)

The conveyor belt scraper according to claim 2, wherein the second and third retention sections are shorter than the first retention section in the direction of extension from the second side.

### Claim 4 (depends on 2)

The conveyor belt scraper according to claim 2, wherein only the retention sections are over-moulded by the scraper member.

### Claim 5 (depends on 1)

The conveyor belt scraper according to claim 1, wherein at least one retention section includes a number of keying formations which are adapted to bond to a material used to form and being over-moulded onto the base.

### Claim 6

A conveyor belt scraper comprising:
a base comprising
an elongate body of uniform cross-section having a bridging piece with a first side and a second side opposed to the first side,
first and second spaced apart legs on the first side of the bridging piece; and
a first retention section, a second retention section, and a third retention section, and wherein the first retention section on the second side of the bridging piece-is flanked by the second and third retention sections which are respectively spaced from the first retention section and which extend upward from the second side of the bridging piece; and
a scraper element formed by over-moulding the same onto the body and over the first, second and third retention sections of the body, wherein at least one of said first second and third retention sections includes a number of keying formations which are adapted to bond to a material used to form the scraper element.

### Claim 7

A conveyor belt scraper comprising:
a base comprising
an elongate body of uniform cross-section having a bridging piece with a first side and a second side opposed to the first side,
first and second spaced apart legs on the first side of the bridging piece; and
a first retention section, a second retention section, and a third retention section, all of which extend upward from the second side of the bridging piece; and
a scraper element formed by over-moulding the same onto the body and over the first, second and third retention sections such that no portion of any of the retention sections is exposed after the scraper element is formed.

### Claim 8 (depends on 6)

The conveyor belt scraper according to claim 6, wherein the second and third retention sections are straight and entirely enclosed within the scraper after the same is formed by over-moulding.
