摘要

A folding station (S3) for folding the cardboard blank (C) includes an inlet (IN) and an outlet (OUT), and is preliminarily arranged to receive the cardboard blank (C) at the inlet (IN); Corrugated blank (C) has two lateral edges (B1, B2) and two longitudinal edges (BL), two longitudinal fold lines (L1, L2), and four lateral folds Line of sight (T1, T2, T3, T4) with two longitudinal crease lines (L1; L2) in the corrugated blank (C) and two longitudinal crease lines (L1, L2) , And a central zone (SC) between two lateral zones (SL1, SL2) outside the two longitudinal fold lines (L1, L2), and the folding station (S3) further comprises two Side area (SL1, Sl2) It comprises a cut (I1, I2, I3, I4), to define a series of flaps. The folding station (S3) further transports the cardboard blank (C) in the forward direction (V) and stops the cardboard blank (C) at a given position (Z) (4); conveyor ( A first bending bar (61) positioned at position (Z) by the side of the first side of 4) and a second positioned side (Z) by the side of the second side of the conveyor (4) It has two folding bars (62). The first folding bar (61) and the second folding bar (62) are actuable to rotate, and the flaps present in the two lateral sections (SL1, SL2) are connected to a cardboard blank (C Fold into the relevant part of the central area (SC)).
