• a stacking device according to the invention comprises a stacking head E with a vertical feed path for the notebooks C on a horizontal stacking table T.
• the vertical feed path of the notebooks C is defined between two series of drive belts 1, 2 of the notebooks C.
• a first series of belts 1 (shown in dotted lines) defines an interior vertical wall in the stacking head E and a second series of belts 2 (shown in dotted lines) is arranged opposite said internal vertical wall towards the outside of the stacking head, the notebooks C being guided between the internal vertical wall and the external drive belts 2.
• These external drive belts 2 are mounted on a support and, more precisely, said belts 2 are stretched around a frame 3 extending along the inner vertical wall, the belts 2 being at least guided on rollers. guide 4 mounted free to rotate at the lower end of the chassis 3.
