  • the means used are of relatively economical design and that, moreover, the contact setting rate can be very high since all the operations are controlled positively, while at the same time the results obtained are quite constant and readily adjustable.
  • the length of the wire sections which will form the desired contacts subsequent to riveting, heating or the like can be readily increased or reduced. It is thus possible to modify at will the characteristic on the said contacts.
  • the machine may be adapted to any press and used for any support, irrespective of its thickness.
  • the number of contacts set simultaneously by one and the same press can be relatively great.

  • the device 10 supplying the wire 70 is of a known type per se and comprises a slide 11 urged in the direction of the arrow F, by a spring 12 bearing upon an abutment 13 solid with the stationary portion 14 of the device 10.
  • the slide 11 moves on the portion 14, for instance in grooves.
  • the cam 42 acts upon the roller 15 mounted on the slide 11 so as to push the latter back in the direction of the arrow F against the action of the spring 12, thus compressing the latter, as shown in P16. 2.
  • a movable gripper 16 mounted on the slide 11 bears upon the wire 70 so as to drive it in the direction of the arrow F every time the slide 11 moves in this direction.
