Abstract
A blind rivet having a hollow rivet body made of plastic, an elongated shank with a bore, a head at one end of the shank and a foot end on the opposite end of the shank, and having, in the bore, a mandrel that has a mandrel shank with a drawing end and a mandrel head that acts on the foot end, the shank has a first region located between the head and the foot end, and has a second region with reduced cross-section and reduced wall thickness as compared to the first region. The regions arranged such that, as a result of a process in which the head is pressed against one side of a workpiece and the foot end is simultaneously drawn toward the other side of the workpiece with the aid of the mandrel, the wall of the shank forms a roll fold with an annular bead.
