  • the carrier carrying the arms is expediently mounted in two mutually opposite supporting pieces which are guided in the same direction and parallel to one another in side parts of the side posts of the frame. In this way, a height compensation between the transfer station and the delivery station can be achieved. Furthermore, height adjustment must usually also be carried out if the packages to be created are to be turned between the transfer and delivery stations.
  • the carrier expediently forms the web part of a U-shaped frame, the legs of which are mounted in the support pieces so as to be pivotable about an axis parallel to the web part.
