Abstract
Method and apparatus for erecting cartons wherein a flat folded carton blank is conveyed to the apparatus where it is momentarily stopped. Suction cups pull the underside of the blank downwardly against a breaker bar to bow the underside downwardly pulling the leading and trailing ends of the blank toward each other and thus bowing the upper carton side upwardly. With the carton thus partially opened, an overhead opening element rotates into engagement with a trailing side panel of the carton to swing it through an arc of about 90.degree. until it is substantially vertical. An overbreak element thereafter engages the now vertical trailing side panel and swings it through another 90.degree. to overbreak the carton. In this condition, the carton is conveyed out of the erecting apparatus and into transport lugs of the transport conveyor of a cartoner.
