PROCEDIMIENTO PARA LA FABRICACION DE PATILLAS O LENGUETAS DE EXPANSION EN REMACHES CIEGOS.

摘要

The disclosure relates to blind rivets and to an improved method of making such rivets. Symmetrically disposed slots are formed in the plain end of the rivet by means of chisel-type or edge-cutting tools so as to form several segments or lugs which, in use, may be spread apart by a spreading pin or the like to secure two or more members together.
