• the associated advantage consists in conferring an increased bending capacity on the trays 31. Indeed, the plates 31 having more material than the teeth 32, they are less able to flex axially than are the teeth 32. Decrease the dimensions of the cross section of the core 12 in the zones Z1 carrying the radial rows plates R31 makes it possible to increase substantially the radial extension of said plates 31 - distance between the base 33 of said plates and their free end 35 - and thus, to make them more flexible axially.
