PCT No. PCT/EP98/00105 Sec. 371 Date Sep. 3, 1998 Sec. 102(e) Date Sep. 3, 1998 PCT Filed Jan. 9, 1998 PCT Pub. No. WO98/30832 PCT Pub. Date Jul. 16, 1998The device is used for fixing rivets, buttons, etc., which comprises an article lower part and an article upper part, to a fabric. It has a lower gripper (1) supporting the article lower part and a plunger (2) performing the riveting stroke. With the lower end of the plunger is associated an upper gripper (3) acting on the article upper part and with the upper end is associated a drive mechanism (4) responsible for the stroke movement. A finger guard bow (11), associated with the plunger and extending into the movement path of the upper gripper and which, after initiating a plunger riveting stroke, on encountering an obstacle and before reaching its end position, stops the drive mechanism and consequently the plunger. A significant constructional simplification of the device is obtained in that the finger guard bow (11) is connected to the plunger (2) acting on the gripper (3) in the sense of an entrainment, on initiating the stroke movement by the drive mechanism (4), by a coupling element (13), which initiates the stopping of the drive mechanism when the ginger guard bow (11) strikes the obstacle (14). The coupling element (13) is formed by a two-jointed bar (15) with an inserted spring (16). An electric switch (19) is located in the circuit (20) controlling the drive mechanism (4) of the plunger (2) and responds to a length change of the two-jointed bar (15) through the finger guard bow (11) striking the obstacle (14) accompanied by the tensioning of the spring (16).
