  • the present invention relates to transfer machines with free carriages and, more particularly, to those comprising independent and motorized free carriages.
  • a transfer machine having at least one rectilinear traffic lane requires, in frequent cases, the installation of diversions to bring the carriages facing work stations excluded from the path line, when, for example, their execution time is greater than the longest time taken as the basis for determining the overall operating cycle.
