  • Patent number: 5500998
    Abstract: Tongs for dressing conductor ends have two handles (3, 11) which can move relative to one another, at least two dressing stations (4, 8), and a drive device (10, 12, 20), via which the dressing stations can be driven during operation of the handles. At least one (18, 19) of the dressing stations (4, 8; 18, 19) can be coupled to the drive device (10, 12, 20) with the aid of the conductor end (28) which is to be dressed. The dressing station which can be coupled to the drive device is thus driven only when this is also actually required.

  • Patent number: 5400941
    Abstract: Core end sleeves (22) are linked to one another in the form of a belt and in each case have a metal sleeve (70) in the front region and a plastic sleeve (71), which partially engages over the metal sleeve (70), in the rear region, via which the core end sleeves are connected to one another. The plastic sleeves are in each case provided on their rear end with a projection (72) which points to the rear and rests on an outer side of the belt. The height, running at right angles to the plane of the belt, of the projection (72) is independent of the diameter of the plastic sleeves (71). Core end sleeves (22) for different conductor cross-sections can thus be transported using one and the same core end sleeve guide track (63) which has a guide groove (67) on its one side wall (65) for the projections (72).

  • Patent number: 5347705
    Abstract: Pliers for dressing conductor ends have two handles (3, 11) which can move relative to one another, a plurality of dressing stations for the conductor ends, and a drive device (21) via which the dressing stations can be driven during operation of the handles (3, 11). One of the dressing stations is constructed as a crimping drum (18) which can be displaced axially and is supported such that it can rotate and be coupled to the drive device (21) in the axially displaced position over only one dressing process. In this position, the station can be locked via a flange (52) which projects radially from it. This flange (52) extends over the overall circumference of the crimping drum (18) and has at least one recess (51).
