  • Blind-rivet setting device
    Patent number: 5655289
    Abstract: A blind-rivet setting device, includes a tension device, an intermediate storage and computing device, an evaluation device and an electrical circuit. The tension device is driven by an electric motor having an input current and provides a tensile force on the blind-rivet. The intermediate storage and computing device stores and computes a rated current range depending on the material and dimensions of the blind-rivet. The evaluation device has a comparator for monitoring the input current received by the electric motor. The electrical circuit produces an error message when the maximum value of the input current is not within the rated current range.
