  • Patent number: 6918328
    Abstract: Lack of balance of a crank mechanism, which reciprocates a ledger having one or more guides for one or more cigarette rods or filter rods each issuing from a maker and being subdivided into a row of cigarettes or filter mouthpieces, is at least partially counteracted by at least two counterpoises one of which orbits about the axis of the crank mechanism in a first direction and the other of which orbits, in a second direction counter to the first direction, about a second axis laterally offset relative to the axis of the crank mechanism. A third counterpoise can be mounted for orbital movement about the axis of the crank mechanism and, if utilized, is angularly offset relative to the first counterpoise. The prime mover for the crank mechanism orbits the first and third counterpoises in the first direction, and the second counterpoise in the second direction.

  • Patent number: 6782889
    Abstract: Apparatus for controlled removal of surplus material from one or more tows of tobacco particles, filter material for tobacco smoke or the like employs at least one belt conveyor for each stream. The outer side of such belt conveyor is provided with recesses which receive particulate material at the stream forming station or stations. Each stream is equalized by a discrete trimming device which employs a pair of cooperating rotary knives having circular cutting edges and serving to remove the surplus prior to compacting and wrapping of the thus obtained rod-like filler or fillers into web(s) of cigarette paper of the like. The material which has entered the recesses of the belt conveyor(s) contributes to greater density of the corresponding portions of the fillers or fillers, and such densified portions are severed by a cutoff to be located at the ends of plain cigarettes or at the tobacco-containing ends of filter cigarettes.

  • Patent number: 6732740
    Abstract: The filler of a cigarette rod has a tubular portion made of shredded tobacco and surrounding at least one row of spherical inserts made of aromatic material or aerosol. The tubular portion is made by feeding tobacco shreds against the underside of the horizontal lower reach of a foraminous conveyor belt advancing beneath a suction chamber to accumulate a first layer of shreds. The inserts are delivered to the underside of the first layer and are attracted thereto by suction. A second layer of shredded tobacco is assembled by showering shreds against the underside of the first layer where the second layer underlies the spherical inserts. The thus obtained filler is draped into a web of wrapping material to form a cigarette rod ready to be subdivided into sections of unit or multiple unit length. The spherical inserts are expelled from a revolving receptacle under the action of centrifugal force to form a row which is conveyed toward the underside of and advances with the first layer.

  • Patent number: 6708695
    Abstract: An asymmetrical trimmer disk/paddle wheel apparatus for trimming tobacco from a stream or braid of cut tobacco in a cigarette maker comprises a pair of counter rotating disks with a plurality of pockets arranged to coact with one another to trim off excess tobacco and create densified regions at the filter and lit ends of a cigarette rod product made in the maker. The pockets are constructed with different widths and depths to provide densified regions of different densities and lengths at the filter and lit ends of the cigarette rod product. The cigarette rod product formed by the asymmetrical trimmer disk/paddle wheel apparatus has an improved density profile that minimizes rejects at maker speeds up to about 8000 rods/minute.

  • Patent number: 6478031
    Abstract: This invention is concerned with improvements to a ledger for a rod-making machine of the type comprising a rod supporting part (14, 16) which is pivotally mounted on two linear motion devices (10; 12) each comprising a fixed gear (A), a first orbiting gear (B) which is preferably smaller than the fixed gear, and a pair of connected coaxial gears (C) and (D) of different diameter which also orbit about the axis of the fixed gear and which mesh respectively with the fixed gear and first orbiting gear (B), such that the effective gear ratio between the fixed gear (A) and the first orbiting gear (B) via the other two gears is 2:1, the rod supporting part being pivotally connected to the first orbiting gear (B) or to a crank connected thereto. According to the main improvement, an assembly including gears B, C and D and parts carrying them at appropriate positions is arranged to be readily replaceable to achieve a rod length change.

  • Patent number: 6390100
    Abstract: A continuous rod with a composite filler having a core constituting a small-diameter cigarette rod and a tube surrounding the core and being confined within a converted web of cigarette paper has axially spaced-apart densified sections in the core as well as in the tube. When the continuous rod is converted into a series of discrete cigarettes, it is severed simultaneously across the densified sections of the core as well as across the densified sections of the tube. If the densified sections of the core are not confined within the densified sections of the tube, a trimming device of the maker of the core is adjusted to shift the locations of the thereafter formed densified sections of the core until such densified sections register with those of the tube.

  • Patent number: 6202648
    Abstract: A cigarette rod wherein a flexible tubular insert is surrounded by smokable material which, in turn, is surrounded by a wrapper of cigarette paper is formed by advancing the insert from a source at a variable speed toward one or more stations where the running insert is confined between two layers of smokable material. A combined monitoring and regulating system is provided to monitor the extent of sag of the insert between the outlet of the source and the confining station(s), to generate signals denoting the extent of sag, and to regulate the speed of a motor for the insert at the outlet of the source in response to such signals. The purpose of the combined signal generating and regulating system is to maintain the extent of sag of the insert between an upper threshold value and a lower threshold value.
