  • the wedge jaw 30 is moved in the direction of the first movable press jaw 20 with the aid of the first drive 23 and the first drive device 22.
  • the wedge jaw 30 is pressed from its rest position along the first guide device 18 in the direction of its working position.
  • the contact geometry 29 slides along the first slotted link slope 36 of the slotted guide 35, as a result of which the first movable press jaw 20 is pressed with the aid of the gear device 32 in the direction of the further press jaw 220 during transfer (see FIG Fig. 7 ).
  • step b) the wedge jaw 30 is positioned between the base structure 17 and the first movable press jaw 20.
  • the wedge jaw 30 is brought into operative connection with the first movable press jaw 20 by the contact surface 31 pushing the first movable press jaw 20 and due to the wedge angle ⁇ between the contact surface 31 and the base surface 34 of the wedge jaw 30 lifts the first movable pressing jaw 20.
  • the wedge jaw 30 is with the help of the first drive device 22 in the Working position and at the same time the first movable press jaw is transferred to the crimping position (see Fig. 8 ).
  • the contact geometry 29 designed as a slide bearing slides along the further slotted link slope 37 of the slotted guide 35, which is flatter than the first slotted guide, whereby the first movable press jaw 20 is pressed further in the direction of the further press jaw 220 with the aid of the gear device 32 during transfer. Subsequently or at the same time, the first movable pressing jaw 20 is transferred in the direction of the latching position with the aid of the prestressing element 27 (see FIG Fig. 2 ), so that the first movable press jaw 20 is finally in the crimping position.
  • a crimp connection is then crimped with a further press jaw 220, with at least one crimping tool 216 being arranged on one of the two press jaws 20 or 220 (step c)).
  • the further press jaw 220 is guided to the first movable press jaw 20 with the aid of the crimping drive 151, so that the crimping tool 216 can produce the crimp connection.
