ABSTRACT:
A roller cradle of an inherently stable furnace comprises a contact surface whose rest portion has a curvature which is less than that of the remaining contact surface portions. The rest portion is preferentially flat and the remaining portions are of involute form. The geometry of the roller cradle is such as to provide an approximately constant restoring moment. Sufficient restoring moment is ensured in the case of small tilt angles.
