Used Box & Case Erectors & Formers. A case erector is a machine that takes a flat-packed cardboard box and forms the blank into a shape using either pin & dome systems (mechanical), vacuum-assisted systems (pneumatic), or a combination of both. Once formed, case erectors can seal the bottom of the case using tape or glue, or leave the bottom of the case unsealed. The case opening can be facing up or to the side. Special case erectors can be designed to erect bliss boxes, insert partitions into a box or case, or to erect a case and insert a bag into the case for a bag-in-box application.
