  • Patent number: 4367758
    Abstract: A cigarette manufacturing machine of the continuous rod type in which a stream of tobacco particles flows upwardly through a vertical duct and feeds a conveyor system to form a tobacco layer or filler and feed it to a continuous cigarette rod forming apparatus. The conveyor system includes an air-permeable mobile belt which spans the duct outlet and extends to the cigarette rod forming apparatus. During its formation and transfer, the tobacco layer is retained on the belt by suction applied to the belt face opposite the face holding the filler. The suction is divided with first suction apparatus operating on the belt portion disposed over the duct outlet, and with second suction apparatus, independent of the first, operating on the belt portion between the duct edge and the cigarette rod forming apparatus.

  • Patent number: 4265073
    Abstract: Disclosed herein is an improved apparatus for forming and overwrapping the batches of products commonly known in Italy as "sticks".To form batches of products either flat, one on top of the other, or tip to tip along one of their narrower sides, a first intermittently rotating head provided with radial compartments for accommodating the individual products is placed at the side of a second head that rotates intermittently around an axis perpendicular to that of the first rotating head, is coupled to a wrapping mechanism and is provided with radial compartments, each suitable for accommodating one batch of products.The said second rotating head and the wrapping mechanism are supported in such a way that they are able to move in the direction of the first head so that the second rotating head can arrive at two different stations to receive the individual products from the first rotating head. The said two stations, angularly interspaced by 90.degree.

  • Patent number: 4209955
    Abstract: The device is conventionally associated to a cigarette packaging machine and comprises a hopper for successively distributing individual layers of adjacently disposed cigarettes into transferring means which successively transfer each layer into compartments intermittently moved in front of said transferring means. A plurality of layers are superimposed in each compartment to form a bundle to be fed to the wrapping means of the packaging machine. During the transferring, the layers are compelled to pass through a passage delimited by side guiding members and by an upper and a lower light-transparent guiding plate, said passage having a width substantially equal to the width of a layer and a height substantially equal to the diameter of a cigarette. The upper plate has a slot in the direction of the transverse dimension of the passage and this slot is subjected to the light rays generated by a light source transversely disposed relative to said passage and above said slot.

  • Patent number: 4196560
    Abstract: A dispensing apparatus for machines for packeting cigarettes into hinged-lid rigid type cigarette packets is of the type comprising an intermittently rotating wheel having radially disposed compartments for housing individual cigarette packets. A dispensing channel is associated with the wheel and upper and lower heated plates cooperating with the compartments. A pushing member is provided at the end of the dispensing channel to push, during the normal operation of the apparatus, the individual packets into a first track coplanar to the dispensing channel. A control mechanism, should the wheel accidentally stop, acts on a pair of mechanical systems which cause the spacing apart of the plates from the compartments and further starts a timer.
