The BBS PK40 is a folding machine — sometimes referred to as a folder gluer — designed to automate the boxing and stacking of folded cartons at the end of a folding and gluing line. Machines of this type are a core part of packaging production, gathering and collating finished folded boxes into counted, stacked bundles ready for dispatch. BBS is a specialist manufacturer in the carton packaging machinery sector, known for producing equipment that integrates into folder gluer lines.
This particular unit is described as an auto-pack system built for seamless connection with both new and existing folding and gluing machines. Its compact footprint is a notable design feature, with overall dimensions of 2,600 mm × 1,850 mm × 1,100 mm, allowing it to fit into production environments where space is limited. A patented vertical stacking mechanism enables boxes to be stacked without the need for a backstop, which the manufacturer states improves both usability and workflow efficiency.
The machine handles a broad range of box formats. Compatible box types include straight-line boxes, 4-corner boxes with lids, and 6-corner boxes — covering the most common constructions encountered in folding carton production. Cardboard weights from 200 to 600 g/m² are supported, giving the machine flexibility across a wide spectrum of board grades from lighter consumer packaging to heavier, more rigid carton stock.
Box size capacity spans a maximum width of 320 mm down to a minimum of 70 mm, and a maximum length of 400 mm down to a minimum of 80 mm. The maximum stacking thickness the machine can accommodate is 70 mm per bundle, which governs the depth of each collated stack before ejection. The machine is located in Italy and is offered in used condition.
