Verfahren zur Erzeugung der bei Gebrauch aufzuspreizenden Lappen von Blindnieten und nach diesem Verfahren hergestelltes Blindniet

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.
