摘要：
A machine for making steel wire springs particularly intended for the watch-making industry has a tray carrying fanwisearranged tool holders about the center of the tray and radially slidable towards the center of the tray with tools for shaping a spring from a wire coming out from the center of the tray. A means for actuating the tool holder include a gear mounted parallel to the tray and meshing with pinions distributed about the gear, each of these pinions being secured on a shaft carrying a cam controlling the advance of the tool holder, which is spring urged rearwardly.
