During the manufacturing process, it is necessary to check the integrity of the tissue flowing at very high speed from the rollers of the automatic machine. 

The high tension of the material could cause it to tear. 
The M12 photoelectric sensors of the Datasensing DM Series are able to correctly detect both the presence of any tears and the incorrect positioning of the roller or its end stroke, allowing the operator to intervene immediately to replace or realign the roller.
