Claim 7:
8. A method for the dip treatment of articles, comprising the steps of:
a) dipping articles to be treated completely or partially into a treatment liquid with which a dip tank is filled;
b) providing a conveying system which defines a conveying path and comprises at least one transport carriage, which is moved along the conveying path in a transporting direction and has a fastening device to which at least one article is fastened, the conveying path of the conveying system dividing into sub-paths, and articles are guided on at least one first sub-path to the dip tank or to a dipping region of the dip tank, and/or articles are guided on a second sub-path past this dip tank or past this dipping region of this dip tank even when the dip tank or the region of the dip tank is occupied;
c) selectively connecting and disconnecting
a. a first switch point section to connect and disconnect the at least one first sub-path to move the articles to be treated by the conveying system toward the dip tank, completely or partially into the interior space of the dip tank, out of the dip tank and away from said dip tank, and
b. a second switch point section to connect and disconnect the second sub-path to provide a bypass route for the articles to be treated around the dip tank or the dipping region of the dip tank, wherein
only one of the first switch point section or the second switch point section are physically connected to the conveying path at any given time;

d) selectively connecting and disconnecting
a. a third switch point section to connect and disconnect the at least one first sub-path to allow articles to return to the second-path from the dip tank or continue along the second sub-path, and
b. a fourth switch point section to connect the second sub-path to a second first sub-path to move articles to be treated toward a second dip tank, completely or partially into the interior space of the second dip tank, out of the second dip tank and away from said dip tank, wherein
only one of the third switch point section or the fourth switch point section are physically connected to the conveying path at any given time, and the first switch point section and the second switch point section are selectively connected and disconnected independent of the third switch point section and the fourth switch point section.
