  • Patent number: 4558778
    Abstract: A device for sequentially transferring cigarettes or cigarette pairs from a rectilinear, preferably horizontal path, so-called "longitudinal", along which the cigarettes are moved forward in a file in which they are axially aligned, to a rotary fluted drum with its axis of rotation being parallel to the rectilinear horizontal path, the transferred cigarettes being successively deposited, parallelly arranged side by side, onto the drum in a row, which is transverse with respect to the cigarette file moving along the longitudinal path. The transferring device includes a rotary drum positively driven at a constant speed, onto which there is mounted a number of swinging arms star-like arranged at an equal distance therebetween and carrying each one a suction head for picking up and transferring the cigarettes.

  • Patent number: 4296660
    Abstract: The device for feeding filter plugs to a demand drum comprises, in combination, a gravity-feed hopper containing a supply of multiple length filter rods, the hopper being closed, in correspondence of its bottom end, by a rotating fluted drum wherein each flute of the drum is capable of housing a filter rod. The filter rods, thus removed from the hopper, are cut into three filter plugs, which are delivered, axially aligned, onto a horizontal conveyor belt subdivided into three tracks. As a continuation of the conveyor belt there is provided a horizontal fixed sliding surface onto which the articles slide in three rows, each leading article of the three rows being pushed by the subsequent ones, until the leading article reaches an abutment member, where it is firmly positioned. Also the sliding surface is subdivided into three tracks.
