Abstract (en)
[origin: ES268537U] A method for the manufacture of stopper wirings which consists: in shaping wires to a profile including in a first plane a central portion in the form of an arc of circle and two straight branches, in disposing the shaped wires to form a complete ring, the straight branches extending outwardly from the ring, in twisting each branch along a first portion of its length starting from the ring, in twisting locally the remaining portion of each branch in a zone intermediate between the twisted portion and the outer end, and in rolling the end of the remaining portion of each branch in the shape of a loop to form one leg of the wiring.
