Patent number: 5435326Abstract: A smoking article having a controlled yield of wet particulate matter and a method of making a smoking article with predetermined total and per puff yields of wet particulate matter. The smoking article has a tobacco rod connected to an air ventilated compound filter having two abutted filter segments, a rod end segment with a passage therethrough and a mouth end segment. The pressure drop of the abutment interface between the segments is selected to be in a range of from about 10 mm to about 100 mm water gauge. The total pressure drop of the filter including the interface and the amount of air dilution can be selected to provide a smoking article with a level per puff yield or a decreasing per puff yield.Type: GrantFiled: July 27, 1993Date of Patent: July 25, 1995Assignee: R. J. Reynolds Tobacco CompanyInventors: Thomas L. Gentry, Russell D. Barnes, Richard L. Blakley, Charles R. Ashcraft, Juanilla M. Gwyn, James W. Pryor, Henry T. Ridings, Milly M. L. Wong

Patent number: 5163452Abstract: Rods for use in the manufacture of smoking products are provided using a rod-making apparatus. The apparatus includes (a) an unwind unit for continuously supplying a material having a continuous integrity; (b) a rod-forming unit for forming a rod-like composite of the supplied material; (c) a constriction member for constricting the rod-like composite, the constriction member including (i) a material-contacting surface and (ii) a reservoir for supplying an amount of liquid to at least a portion of the material-contacting surface; and (d) a rod-making unit for receiving the rod-like composite and for circumscribing the rod-like composite with wrapping material thereby forming a continuous rod.Type: GrantFiled: March 19, 1992Date of Patent: November 17, 1992Assignee: R. J. Reynolds Tobacco CompanyInventors: Clifford R. Marritt, James W. Pryor, Philip A. Deal

Patent number: 4889143Abstract: Rods are manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands of about 1/32 inch width. The strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod. The continuous rod is severed at regular intervals to provide a plurality of rods of the desired length. The resulting rods have a plurality of substantially longitudinally extending strands provided from shredded sheet-like material. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.Type: GrantFiled: May 14, 1986Date of Patent: December 26, 1989Assignee: R. J. Reynolds Tobacco CompanyInventors: James W. Pryor, Mark L. Raker, Andrew J. Sensabaugh, Jr., Henry A. Hauser

Patent number: 4807809Abstract: Rods for use in the manufacture of smoking products are provided using a rod making apparatus equipped with a web preforming unit. A web of sheet-like material is passed through the web preforming unit and is pleated to form a rod-like composite. The rod-like composite then is circumscribed with wrapping material to provide a rod. The web preforming unit includes an outer frustoconical tube and an inner frustoconical member. The frustoconical member is concentric to the tube, and is positioned coaxially with respect to the tube such that an annular region is formed between the outer surface of the member and the inner surface of the tube.Type: GrantFiled: February 12, 1988Date of Patent: February 28, 1989Assignee: R. J. Reynolds Tobacco CompanyInventors: James W. Pryor, John L. Nelson, Clifford R. Marritt
