This makes it possible to machine the plates in question with greater tolerances and to prevent any deformations on the plates from resulting in a deformation of the guide path.
- the maintenance of the guiding path in the closed position is ensured here, in addition to the shearing work of the elastic cylinders 57, by the clamping effect obtained thanks to the locking device described.

- the locking cylinders also tend to clamp the plates against each other.
- the opening / closing cylinders also.
- the resulting tightening state of the ones and / or others of these cylinders can lead to a sufficient closing resistance of the guide path, for some applications at least.
- the locking / clamping device described although advantageous in that it gives the flanges 5 a good rigidity while maintaining a relatively low mass, appears optional.
- the clamping effect obtained by the device described may be insufficient and require an additional closure device, including directly mounted between the rails 49 for example by means of latches.
- the reinforcement reinforcements described are advantageous in that they make it possible to produce a very rigid flange 5 without increasing its mass. However, in applications where phenomena related to the mass of the flanges 5 would be of little importance, one could obtain a similar rigidity using the thicker plates, for example.
- Plates are described which are assembled via hinge connections, which allow the plates to pivot relative to one another.
- the invention is not limited to this type of connection, but encompasses all the connections that could allow a set of plates forming a flange to adopt a closed position and an open position, whatever the relative movement. allowed by these links.
- annular guideway described above is particularly suitable for working parts of revolution in particular.
