  • Patent number: 9131731
    Abstract: A method of destructive opening cigarette packs in which the packs are successively mechanically deformed by deflection of at least one wall of each pack toward the outside of the pack, then the deflected wall of the pack is incised from the outside and a pack opening element is slid between the deflected wall of the pack and the cigarettes contained therein, and the pack is opened from the inside by means of the pack opening element. An apparatus for destructive opening cigarette packs using the method according to the invention.

  • Patent number: 8925707
    Abstract: Apparatus for sorting rod-like elements such as each having a defined different length, including a sorting transporter inclined with respect to the horizontal at an angle and having a longitudinal sieve element above and along which a transverse pusher slat moves to shift the elements upwards along the sieve element. The shifted elements are oriented along the pusher slats. The sieve element includes a through opening in the transporter which is divided by askew bars into at least two neighboring through sub-sections. The width and length of each section is selected specifically for one selected length of the rod-like elements so that only the rod-like elements having the length smaller or equal to the one selected length pass through the sub-sections of this section while being oriented along the pusher slats. A system including the apparatus according to the invention and a method for sorting rod-like elements are also disclosed.

  • Patent number: 8930016
    Abstract: Method for arranging rod-like elements including cigarette parts such as filter and tobacco parts, in which elements are delivered to a conveyor having successive sectors which arrange the elements in separate rows along the conveyor. The type, number and location of element transported on the conveyor are determined by at least a single scanning of each successive element on the conveyor. The scanned results are transmitted to a control unit which assigns each sector of the conveyor information according to its contents. The elements are subsequently sorted based on the information received by the control unit according to the type and the number of parts each element is composed of, the orientation of these parts in relation to the direction of movement of the conveyor. Each of the successive elements is transferred to a predetermined receiving area based on the information received from the control unit.

  • Patent number: 8918201
    Abstract: Method and system for arranging rod-like elements, in which an unordered portion of rod-like elements, composed each of at least one part selected from cigarette parts being filter parts and tobacco parts, is delivered to a conveyor which arranges the elements on the conveyor in a plurality of compartments, longitudinally in each compartment and transversely to the direction of movement of the conveyor. The compartments have a length which receives at least one filter part and at least one tobacco part of a cigarette. The type, number and location of parts of the element received in each compartment is defined by at least a single scanning of each successive compartment of the conveyor. The result of the scanning is transmitted to a control unit and the elements are subsequently sorted based on information received from the control unit.

  • Patent number: 8651114
    Abstract: Method of opening a cigarette wrapper including cutting open a cigarette transported in a guiding groove of a feeder of a machine for recovering tobacco from defective and/or substandard cigarettes with at least one revolving disc knife located above the feeder, in which the at least one revolving disc knife is applied to the cigarette in such a way that the axis of rotation on which the said disc knife is perpendicularly mounted lies on a plane parallel to the plane over which the cigarette axis is translated, and the plane of the disc knife does not contain the cigarette axis and is parallel to the said cigarette axis, the possibility of rotation of the cigarette around its axis in the guiding groove is blocked, whereby tensile stress is applied in the cigarette wrapper facilitating its opening. Assembly for applying the method according to the invention.
