Abstract: A guide beam for plural carriages including supporting rails secured to the beam, driving devices disposed along the rails each associated with a carriage and operated by a separate motor, troughs placed along the length of the beam, flexible cables placed in the troughs, and a hollow arm fixed to each carriage and the end of which moves above each trough, the flexible cables placed in each trough being inserted into the end of the arm located above the trough. The guide beam is characterized by guide tracks placed along the beam one for each carriage and by caterpillars for the cables, each being movable above its associated trough in one of the guide tracks, and supporting the end of the variable length of the cables which are inserted into the hollow arm.
