Device and method for feeding a web of a packaging material

A method for feeding a web of a packaging material along a path and towards an application station;

• said packaging material comprising a plurality of areas at which said application station applies respective opening devices;
• said method comprising:
• advancing said web along a first direction parallel to said path by using first advancing means;
• detecting the positions of said areas;
• and
• generating a plurality of measure signals which are associated to positions of said areas;
• transversally moving, on the basis of at least one of said measured signal, said first advancing means along a second direction transversal to said path.

A device for feeding a web of a packaging material along a path and towards an application station;

• said packaging material comprising a plurality of areas at which said application station applies, in use, respective opening devices;
• the device comprising:
• a roller motor connected to a roller to rotatably drive the roller while the roller is in contact with the web to advance the web along a first direction parallel to the path;
• a sensor configured to generate a plurality of measure signals associated with positions of the areas of the packaging material;
• and
• a first motor operatively connected to the roller and controlled according to at least one of the measure signals to move the roller in a second direction transverse to the path.
