Abstract
A system for inspecting individual bags during stacking facilitates defect-free stacking of the bags for subsequent use with automated filling equipment. The present system includes a camera inspection system which is operated to inspect a predetermined portion of each bag, such as a header portion thereof, preferably in conjunction with stacking of each bag on an associated wicket. The present system is particularly suited for identifying bags having a folded corner and/or determining that only one of a pair of holes of a hag has been placed on the associated wicket.
