Designed to immobilise the chain conveyor to ensure that it does not move transversally, and to make it easier to clean it, the main characteristics being that each one of its cogs (3) is equipped, only on its rear wall (10), with a crest (9) that is off-centre with respect to the imaginary plane of the cog running perpendicular to the centreline of the crown, which crest has to be inserted between the protrusions on the links that form the chain. The layout of this crest (9) is trapezoidal and isosceles, diverging towards the cog (3), and the lateral surfaces are concave, in such a way that the aforementioned lateral surfaces are joined to the marginal surfaces of the surface (10) of the cog (3), in a markedly rounded way, so there are no sharp edges, which makes it easy to clean the crown when, for example, a jet of water is sprayed onto it.
