Abstract: A rivet setter has a holder for holding a blind rivet prior to said rivet being set by means of the setter. The holder has a central cylindrical passage, the diameter of which is somewhat greater than the diameter of the mandrel. At least two, preferably three clamping jaws, which are guided in radial slots so as to be radially and axially displaceable, act on the mandrel. The width of the slot is smaller than the diameter of the mandrel.

Abstract: What is proposed is a device for setting blind rivets which has a motor-actuated pulling device for pulling on the rivet mandrel. The pulling device comprises a disk spring which is initially stressed during the actuation of the pulling device. As soon as the force exerted on the rivet mandrel by the pulling device is sufficiently large such that the rivet mandrel breaks off as intended, the previously stressed spring suddenly relaxes and results in the part of the pulling device which engages on the rivet mandrel butting against a stop. As a result, this part of the pulling device then stops abruptly whereas the rivet mandrel is projected further. It is possible in this way for the rivet mandrel to be conveyed into a rivet mandrel container present in the housing without a user having to execute a particular operation for this purpose.
