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. Upon operation of the mechanism consequent to rotation of one of the discs in correct time relationship with the speed of the pack along the conveying path, the folder element engages the flap in a direction which is transverse to the direction of movement of the pack, while simultaneously accompanying the pack in its movement, and at the same time moving cyclically to-and-fro perpendicularly with respect to the face of the pack against which the flap is folded.
