<p>A system for automatic inspection and ejection of cartons in a packaging machine includes detection elements (20, 22) for determining whether a carton (C) has assumed a predetermined configuration at a predetermined point in its path of travel. Carton ejection elements include rollers (30, 32) which are actuated to eject a carton (C) when the detection elements (20) determine that the carton has not assumed the predetermined configuration at the predetermined point in its path of travel. A synchronous relationship between a flow of cartons (C) and a flow of groups of articles (G) to be packaged is preserved and as cartons leave the carton inspection and ejection station of a packaging machine.</p> |
