  • Patent number: 6378194
    Abstract: In a method for joining workpieces, in particular press fittings (24) to a pipe (23), the pressing device (1) is placed with its at least two pressing jaws (21, 22) in the open position against the joining point of the workpieces 23, 24), and the pressing jaws (21, 22) are then moved with respect to one another by means of a jaw drive (7, 50), while the workpieces (23, 24) deform plastically, into a terminal pressed position in which, at the latest, the application of power to the press jaws (21, 22) ends. According to the invention, the power of the jaw drive (7, 50) is controlled in such a way that, at least toward the completion of pressing, the pressing jaws (21, 22) have less kinetic energy than without a power controller. The invention further concerns a pressing unit (1) for carrying out said method.

  • Patent number: 5868021
    Abstract: In a method for binding rope- or cable-type cords with press-fit elements (13), the press-fit element (13) is placed over the cord, and the cord and press-fit element (13) are compressed radially and plastically via a pressing device (1, 11, 31, 41, 51) that is equipped with pressure clamps (3, 4), such that a reduction in the material cross-section results. In accordance with the invention, the longitudinal extension of the cord and/or the press-fit element (13) is gauged during the pressing process, and compression is halted when a predetermined end value (db) for the longitudinal extension has been reached.
