<p>The present invention relates to a device for cutting a web of foil into lengths in a machine for packing cigarette packets. This device comprises at least one pair of continuous wheels for feeding the foil between fixed guides and a pair of cutting blades placed opposite each other below the said feed wheels. At least one of the cutting blades is driven in continuous rotation about an axis parallel to the feed wheels. A cylindrical pad of absorbent material freely rotates about its own axis set parallel to the axis of rotation of the said rotating blade and is in such a position that, during its rotatory movement, the said rotating blade comes into contact with the said cylindrical pad of absorbent material which may be pre-soaked in vaseline oil.</p> |
