A cardboard case former is a machine that takes box material (corrugated cardboard sheets) that has been set in place and assembles cardboard boxes. The only step to be done manually is setting the box material. All steps of the case-forming line can be automated, with everything from taking the box material to 3D composition, bottom taping, and discharging handled by the machine. Changing types can be done with ease, and it can be used either as a standalone unit or as part of a line system.
