    Abstract: A method is described for processing waste materials in the form of filter rods, filter cigarettes and the like comprising filter material with inner hollow volumes accessible from the outside and at least one other material component, in particular paper and tobacco, wherein the following process steps are carried out: the waste material is distributed in a liquid in a pressure vessel. By increasing the pressure or decreasing the temperature an inert gas is dissolved in the liquid. Subsequently the temperature is increased or the pressure decreased so that fine gas bubbles develop within the filter material which permits the latter to float whereby a separation from the further material components to be separated is possible. With this method a separation of the waste material into its individual component parts is possible so that for example valuable filter material in the form of cellulose acetate is obtained in highly pure form and can be used again for the production of filter materials.

  • Patent number: 5207735
    Abstract: Apparatus for reclaiming tobacco from rejected cigarettes is provided. A receiving drum having holes to receive the rejected cigarettes is provided coaxial with a fluted drum, so that both drums rotate in the same direction. Via a control ring turning in synchronization with the receiving drum, jets of compressed air eject the tobacco from the rejected cigarettes, before the empty cigarette wrapper (tube) is also expelled from the receiving hole. A timing disk controls the work cycle. Suction pressure applied to the receiving holes of the receiving drum sucks the rejected cigarette into a predetermined stop position in the receiving hole prior to the application of compressed air. With the aid of restraining needles, the cigarettes are held firmly while the jet of compressed air is applied to expel the tobacco. On release by the restraining needles, the cigarette wrapper (tube) is ejected from the receiving hole to a discharge chute by a jet of compressed air applied via the control ring.

  • Patent number: 5086790
    Abstract: A method and apparatus for opening cigarette packs involving minimal contact with the cigarettes in the pack and little likelihood of damage or degradation of the tobacco contained in the cigarettes. The invention includes conveying packs to a first location where they are received, moving the packs to a second location where they are pressurized and expanded, moving the pressurized expanded packs to a third location where one end is cut off, moving the packs to a fourth location where impulse is applied to the pack as a whole, resulting in the transfer of the pack to a fifth location, where the motion of the pack itself is stopped, but the inertia of the cigarettes themselves is conserved sufficiently that they are transferred to a conveyance for further processing. The empty packs are disposed of at a sixth location. The method and apparatus is intermittent, involving regular starting and stopping motions.

  • Patent number: 5076291
    Abstract: The method and apparatus of this invention relates to the detipping of cigarettes at high speed without degradation of the tobacco in the tobacco rod and regardless of the intial orientation of the filter tip and the tobacco rod in the apparatus. Cigarettes are fed onto a conveyor belt so that they are traveling in a direction perpendicular to their longitudinal axis. A rolling belt disposed above the conveyor belt straightens bent cigarettes and rolls uneven cigarettes. The cigarettes are then fed onto a fluted rotating drum and aligned on the drum by means of an optical sensor and an air jet so that the filter tip portion of each cigarette is adjacent either side of the drum. Rotating knives are properly oriented so they engage the cigarettes only at the point where the filter tip is connected to the tobacco rod and cut off the filters of the cigarettes.

  • Patent number: 4665930
    Abstract: Cigarettes are perforated by being rolled along a row of pins which are excited, for example by being vibrated. Vibration may be towards and away from the cigarettes so that the pins penetrate as a result of the vibration; the depth of penetration may be varied to control the size of the perforations. Alternatively the vibration may be in a direction transverse to the axes of the pins. In either case the pins may be mounted on a flexible member having a resonant frequency equal to the frequency of vibration. The vibratorary drive may be an electro magnetic device or a piexoelectric crystal. An alternative form of excitation of the pins involves passing compressed air through the pins and into the cigarettes, the pins being tubular for that purpose.
