  • Patent number: 8602035
    Abstract: One embodiment of the invention provides apparatus for manufacturing a smoking article. The apparatus includes an ecreteur having at least one trimming disk configured to trim a tobacco rod for a smoking article to have at least one end region of increased tobacco density. The at least one trimming disk is further configured to trim a body region of the tobacco rod such that the body region has a variable tobacco mass per unit length, where the body region is distinct from said at least one end region of increased density.

  • 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.

  • Publication number: 20030062054
    Abstract: The outfeed unit of a cigarette maker establishes a feed path along which at least one cigarette rod is caused to advance in a predetermined direction from the outfeed end of a beam, on which the rod is formed, toward a cutter device by which the rod is divided into sticks constituting single cigarettes; the unit is equipped with a cut-off device located in close proximity to the outfeed of the forming beam, by which the rod is severed and diverted from the feed path, and, at a given point downstream of the cut-off device, with pinch rollers by which a portion of the rod separated through the action of the cut-off device is removed from a final stretch of the feed path between the cut-off device and the cutter device.

  • Patent number: 6354300
    Abstract: A pusher/cutter drum arrangement for use in the tobacco-processing industry for longitudinal-axial positioning and cutting of rod-shaped objects includes a rotating trough drum containing receiving troughs for receiving, respectively, the rod-shaped objects in a staggered formation. Alignment contacts extend in the receiving troughs and are adapted for aligning the rod-shaped objects with one another in a transverse direction. A rotating cutting means extends through the receiving troughs for making a transverse cut of the aligned rod-shaped objects.

  • 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.
