Abstract

The cutting station (S1) carries out a cutting of a cardboard sheet (F) from a continuous strip of cardboard (S), which continuous strip of cardboard (S) is unwound from a fanfold. The cutting station (S1) comprises: a conveyor plane (1), for advancing the strip of cardboard (S); conveying means (2), for advancing the continuous strip of cardboard (S) along the conveyor plane (1) and for halting the continuous strip of cardboard (S) for enabling cutting thereof; a cutting group (3), predisposed above the conveyor plane (1), and comprising a first rotary circular blade (31) and a toothed second rotary circular blade (32). The cutting group (3) is mounted above the conveyor plane (1) so as to be movable in alternating translation transversally to the conveyor plane (1). The first rotary circular blade (32) is mounted so that the cutting profile thereof passes beyond the conveyor plane (1) at a transversal channel (33), so as to be able to cut the continuous strip of cardboard (S) and obtain a cardboard sheet (F), the toothed second rotary circular blade (32) is mounted so that the cutting profile thereof contacts the continuous strip of cardboard (S) without passing beyond it so as to realise thereon a transversal score line (T4).
