Plant and method for laser scoring

Plant for laser scoring, the plant comprising:

• a plurality of rollers defining a auidina line which supports and conveys a web of flexible material fed from an unwinder station along a conveyance path towards a slitter-rewinder station configured to rewind and/or slit the web ;
• a laser station including a guided path portion through which a portion of the conveyance path can be routed, the laser station comprising at least one laser unit configured to create weakening lines on the web with a certain contour by scoring the web when passing though the guided path portion;
• and
• a labelling station including an additional guided path portion through which a portion of the conveyance path can be routed, the labelling station including at least a labelling unit configured to attach a resealable label in the target zones of the web when passing through the additional guided path portion;
• the guiding line is adjustable to define the conveyance path as a first conveyance path passing firstly through the guided path portion of the laser station and then through the additional guided path portion of the labelling station, or as a second conveyance path passing firstly through the additional path portion of the labelling station and then through the guided path portion of the laser station, or as a third conveyance path passing only through the guided path portion of the laser station skipping the labelling station.
