Patent ID: 8732936

Claim:
A method of operating with a rivet for the coupling and the tack riveting together of a first element and a second element, the rivet being an assembly comprising a breakable mandrel including a mandrel head, and a deformable hollow sleeve defining a first end and a second end, and the sleeve, being integrally formed of one and the same piece, is preformed from a single tapered portion positioned between the two ends, the tapered portion not interfering with tension forces, while facilitating the deformation of the sleeve and permitting the establishment of an installed tension, the first end comprising a preformed head for defining a first support surface on an external surface of the first element, the breakable mandrel being positioned within the sleeve, the method comprising: positioning the rivet such that the rivet traverses two substantially coaxial openings arranged in the first and second elements to be assembled; pulling the mandrel to form a bulb on the second end of the sleeve, the bulb defining a second support surface on an external surface of the second element, to draw the first and second support surfaces nearer each other and consequently draw nearer together the first and second elements, and to crimp the hollow sleeve against the mandrel; and resuming pulling of the mandrel, to cause a rupture of the sleeve at the bulb, removal, by way of the external surface of the first element, of the mandrel head and of a first portion of the sleeve, and detachment of a portion of the bulb from the first portion of the sleeve.
