The invention relates to machines, for the manufacture of springs, of the type which produce springs with a hook in a plane passing through the axis of said spring at one end, and a hook lying in the extension of the last turn of the spiral at the other end. The improvement is that means are provided for transferring the roughed-out spring in front of a device, for straightening the second hook, which is angularly displaced in relation to the machine, the transfer being effected by an axial movement of the blank, followed by rotation, and ending with a further axial movement.
