Abstract
To improve the efficiency of powerful packaging machines for cigarettes or the like, the blanks (10) for wrapping the cigarettes or the like are monitored in respect of correct formation whilst being conveyed along a blanks path (27) to a revolving folding unit (28). Bifurcate photoelectric barriers are positioned on side regions of the blanks path (28) as monitoring units (40, 41). These barriers monitor the state of folding flaps (19. .24), arranged at the side, of the transported blanks (10).
