Abstract:
A method of blind riveting to secure together a plurality of members with aligned apertures, using a blind rivet comprising a tubular shell and a stem extending through the tubular shell, the stem having a head, the stem head being adjacent one end of the shell and the other end of the shell having no preformed radially enlarged head or only a vestigial head of minimal radial and axial extent which is ineffective to exert any substantial clamping force on the members, which method comprises the steps of:inserting the shell through the aligned apertures in the members, from the near face of the near member, so that the aforesaid one end of the shell and an adjacent portion of the shell protrude beyond the remote face of the remote member and until the aforesaid other end of the shell is substantially level with the near face of the near member; supporting the aforesaid other end of the shell with a supporting means and applying a first force with respect thereto to the stem so as to pull the stem head towards the aforesaid other end of the shell and cause the end portion of the shell adjacent the said one end thereof to deform to substantially form a blind head beyond the remote face of the remote member; applying a second force to the near member with respect to the stem, to push the near member towards the blind head until any gap between the members is taken up, with the portion of the shell adjacent the aforesaid other end of the shell then protruding from the near face of the near member; and increasing the aforesaid first force so as to deform the aforesaid protruding portion of the shell to form a near-side head, so that the members are clamped together between the blind head and the near-side head of the rivet shell.
