In-line corrugated cardboard laminating plants

An in-line corrugated cardboard laminating plant, the plant comprising:

• a first corrugating group, comprising a first corrugator and a plurality of first continuous paper web magazines configured to form a first canneté;
• a second corrugating group, comprising a second corrugator and a plurality of second continuous paper web magazines configured to form a second canneté;
• and
• a laminating machine, comprising a magazine of laminated sheets and a coupling unit configured to couple the laminated sheets to the first canneté, the second canneté, or the first and second cannetés so as to form a laminated corrugated cardboard;
• wherein the plant further comprises a gluing unit and a double backer unit, downstream of the first and second corrugating groups and upstream of the laminating machine with respect to a direction of movement along a longitudinal direction in which the first and second cannetés move, and
• wherein the plant further comprises a trimming unit and a transverse cutting unit, downstream of the double backer unit and upstream of the coupling unit with respect to the direction of movement along the longitudinal direction in which the first and second cannetés move, configured respectively to trim to predefined widths in a continuous manner and to cut transversely the first canneté, the second canneté, or the first and second cannetés coupled together.
