Abstract: The folding mechanism for folding a flap of the wrapper against a face of a cigarette pack moving at a uniform speed along a conveying path in a direction parallel to said face, comprises a pair of rotatable discs facing each other and spaced apart, which have their axes of rotation parallel to and excentrically arranged with respect to each other, said axes being further inclined of a predetermined oblique angle with respect to the conveying path of the cigarette pack. The two discs are connected in their rotation by three connecting rods linking respective crank pins provided excentrically on the said discs, so that rotation of one of the discs causes a concurrent rotation of the other disc. Onto one of the said connecting rods there is provided a projecting folder element which presents a flat surface parallel to and intended to engage the flap to be folded.

Abstract: This invention relates to cigarette packaging machines having continuously moving wrapper forming and closing devices. The wrapper forming devices including arbors on which wrappers are formed being rotated 90.degree. on their longitudinal axes during closure of the bottoms of the wrappers and returning to their original position to be filled and transferred to the wrapper closing devices which have holding means for individual packs which are pivoted 90.degree. during closure of the tops or mouths of the packs.
