Converting machine with automatic insertion of the material strip

A machine for converting coils of a material into smaller coils, comprising a loading unit for automatically loading a strip of material into the machine, an accumulation unit of the strip being processed, and a winding unit of the strip on a winding shaft to form respective coils, wherein the loading unit comprises an accompanying system for the strip from the loading unit to the winding unit, said accompanying system being formed by a double chain, comprising a first chain and a second chain and an accompanying bar driven by said first and second chains, wherein the double chain develops as a loop along a path and wherein the accompanying bar is movable along the loop-shaped path and is configured to drive the strip starting from the loading unit to the winding unit and then, after releasing the strip, to return to the starting point in the loading unit,

• wherein the accompanying system further comprises a non-motorized magnetic bar, which slides idly along the path, wherein, in a rest condition, the magnetic bar is housed in a locking-unlocking device, from which it is picked, during the loading step of the strip, by the accompanying bar, so as to be pushed along the path.
