La meule 10 comprend des rainures de mise en prise 14 sur les surfaces latérales de la meule 10 pincées entre les brides 30, 51, les rainures de mise en prise 14 étant formées de manière circulaire autour du centre de rotation de la meule 10. Les saillies de mise en prise 36, 55 des brides 30, 51 sont en prise avec les rainures de mise en prise 14 de la meule 10 de sorte à positionner de manière concentrique le centre de rotation des brides 30, 51 et le centre de rotation de la meule 10.
