A method and device for bending the end tabs of blanks for producing rigid flip-top cigarette packets. The blanks are loaded on a conveyor and are fed continuously along a path with the end tabs slidably engaged in a helical slit, which is in part defined by facing helical surfaces of first and second helical guide elements. The blanks wind over an arc of 180 DEG for bending the end tabs in a U and enabling the bent end tabs to be fed between two pressure rollers of a stabilizing unit. |
