Abstract
Improvements in the construction of hydromechanical adjustment and preload laminators, which comprise, for each upright, firstly, a main adjustment jack, associated with a diver jack with a small section and large stroke, a constant amount of motor fluid being trapped between these two jacks, and secondly at least two preloading jacks, arranged between the boxes, characterized in that the pressure chambers of the preloading jacks of the same upright are, on the one hand, connected to each other and, on the other, connected to the pressure chamber of the diving jack corresponding to the same upright, which is intended to make the preload force unchanged in value.
