摘要

Improvements in the construction of machines for bending or bending links for the manufacture of chains, characterized in that the machine is constituted by two hydraulic cylinders, opposite coaxially, driven by electric controls simultaneously; one that drags the material, and another that acts as a reference stop, moving on the corresponding guide pieces, in which the first is screwed, respectively, and the second screw and nut; the section of the latter being larger, and both fed at the same pressure.
