would not go beyond its scope by making changes. Thus, to ensure the continuity of the successive movements of the machine, use can be made of detection and control means such as probes, photoelectric and infrared cells, limit switches, scales, shutters, etc. and it goes from ground that the machine can also be operated manually. Finally, the invention obviously does not relate to the application of pneumatic jacks and these can be replaced by mechanical, hydraulic or other means.
