Abstract (en)
The control process adjusts the position of the sliding rail fitting over the pipe section in a direction transverse to the pipe, so that the pressure force exerted on the pipe exhibits a defined value. Pref., the required value (Fs) of the pressure force is provided by a required value generator (49) and compared with the actual force value (Fi) to provide a setting signal for a regulator controlling a pressure cylinder (37) for moving the sliding rail.

Die Andruckkraft, mit der ein Andruckzylinder (37) das Rohr (13) in einer Rohrbiegemaschine abstützt, wird von einer Regeleinrichtung geregelt, indem der Andruckzylinder die Gleitschiene (32) quer zum Rohr bewegt, bis die Andruckkraft einen vorgegebenen Sollwert erreicht hat. <IMAGE>
