    Abstract: A conveyor device (1) for conveying substantially round products (11), for example eggs, comprises a support track (4) along which the products (11) can move in a conveying direction during use. Furthermore, the conveyor device (1) comprises a first substantially cylindrical engagement member (5), which extends transversely over the support track (4) with respect to the conveying direction.

The support track (4), downstream of the first engagement member (5) as seen in the conveying direction, has a elevated portion (8) which is located at a distance from the first engagement member (5) which is such that the latter engages on the products (11) on the upward part of the elevated portion (8).
