This type of equipment erects a case from a case blank. The case blanks are pre-scored, and are loaded into a magazine while folded flat. The case is typically formed through the use of pin & dome systems (mechanical) or vacuum assisted systems (pneumatic), or a combination of both. The bottom of the case can be sealed with tape or glue, or the flaps of the closure can be folded but left unsealed. Case erectors may be semi-automatic or automatic, and are able to assemble many different container types such as bliss boxes, partitioned cases, or bag in box.
