摘要

A pressure riveting unit for blind or one-side riveting provided with a two-arm riveting head, there being a pull stud for hollow rivets on the end of each arm. The head is adapted to be turned through 180 DEG , thereby permitting the simultaneous fixing of one hollow rivet blank on one pull stud and the forming of a rivet head on a rivet blank which has been previously fixed on the other pull stud.
