Description

In the cutting zone 14, input material for rivet blanks is fed through the input window 15, for example, wire from the winder to the limiter 16. Turn on the actuator 7, and pull 8, lower, set in motion an eccentric cam 12 that moves the movable down the knife 11, which cuts the measured workpiece from the wire, the workpiece enters the channel b, and the movable knife remains in the lower position, closing the inlet window and preventing air from entering through the slide valve 13. Compressed air jets move the rivet workpiece along anal used in the riveting zone under the presser flange 17. At the same time, the drive is turned riveting tool T is produced riveting, whereupon a tool is supplied A further mer preform rivet turning movement of the actuator 7 kronschteynapolzuna.
