Patent number: 7258122Abstract: A forming device applied to a cigarette manufacturing machine causes a garniture tape 10 to travel through a wrapping section 8, and meanwhile wraps a shredded tobacco layer T in wrapping paper P to form continuously a cigarette rod R. The tape 10 is guided to travel by a forming guide 18 in the wrapping section 8, and is simultaneously bent to have a cross section of an arc that is downward convex. On the other hand, the travel of the tape 10 is guided by a pair of guide rollers 24 in upstream and downstream sides of the wrapping section 8, and the tape 10 is bent to have a cross section of an arc that is upward convex by guide surfaces of the rollers 24. Thus, difference of travel length, that is generated between both side edges and the central part of the tape 10 in the wrapping section 8, is offset by the guide rollers 24.Type: GrantFiled: February 26, 2004Date of Patent: August 21, 2007Assignee: Japan Tobacco Inc.Inventor: Hiroshi Okamoto

Patent number: 6742525Abstract: A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls (e.g. moistened tobacco leaves) and/or homogenized sheet tobacco about a slit mandrel to form a shaped tube. The shaped tube is then packaged for shipment to an end user or consumer. The shaped tube remains in the rolled, shaped tube form inside the package. After the shaped tube is removed from the package, a consumer can fill the tube with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the sheet or to the finished tube to moisturize same. The liquid can include flavoring. The tubes are unfilled when packaged and sent to a consumer/end user in tube form so that they have a “memory” that helps hold a tubular cigar shape after they are filled with selected tobacco fill material.Type: GrantFiled: February 26, 2002Date of Patent: June 1, 2004Assignee: Blunt Wrap U.S.A., Inc.Inventor: Daniel S.

Patent number: 4832056Abstract: A hand operated device for applying cigarette paper to a preformed tobacco rod comprises a forming roller arranged to rotate the rod about its longitudinal axis, a mechanical applicator for applying a pregummed sheet of cigarette paper to the rod as the rod is rotated about its axis, wherein the forming roller is provided along its length with a pair of circumferential helical grooves of opposite chirality, there being further provided a manually operable spigot device adapted to cooperate with the grooves and constrained to travel linearly parallel to the axis of the roller whereby manual movement of the spigot in either linear direction rotates the roller in a constant angular direction.Type: GrantFiled: February 25, 1987Date of Patent: May 23, 1989Assignee: Imperial Tobacco LimitedInventors: Raymond A. Bryant, Beresford R. Gill, Stephen J. Garrett, Christopher R. Bale

Patent number: 4697602Abstract: A machine for rolling bulk material, such as fiber filters and tobacco, and wrapping a sheet member around the bulk material has a flexible apron connected to a roller bar which is rotated with an electric motor. The apron is located over a convex support between side walls having track slots for guiding the roller bar as it rolls up the apron and moves relative to the support. Bulk material placed on the apron adjacent the roller bar is rolled into a generally cylindrical shape within a sheet member as the apron moves over the support. The cylindrical product is discharged from the apron when the roller bar reaches the rear of the slots.Type: GrantFiled: March 28, 1986Date of Patent: October 6, 1987Inventor: Terry L. Pelkey

Patent number: 4319588Abstract: A reusable device for rolling a cigarette from a generally rectangular cigarette paper and for holding the rolled cigarette during consumption thereof includes a rigid elongated member disposed along a longitudinal edge of the paper, and a crimping member for engaging a transverse edge of the paper. The elongated member provides a rolling guide for the cigarette, longitudinally strengthens the cigarette after rolling, and also provides a holder for the cigarette as the elongated member is exposed as the cigarette is consumed by smoking. The crimping member is adjacent the elongated member and prevents movement thereof during the rolling and the smoking of the cigarette. The elongated and crimping members may be integrally formed of a thin, rigid, and elongated wire of low heat conductivity having a hook at one end.Type: GrantFiled: June 2, 1980Date of Patent: March 16, 1982Inventor: Henry J.

Patent number: 4180082Abstract: Disclosed is apparatus for manufacturing cigarettes, cigarillos, and the like. The apparatus comprises a housing, a tray for receiving and measuring a charge of a smokable substance, a cylindrical form for forming a cigarette or the like, and means for opening and closing the form. The tray, which is preferably cylindrical in shape, is open on one side, movable from a first position within the housing to a second position exterior of the housing, and rotatable from a first orientation in which it is open upwardly to a second orientation in which it is open downwardly. The form is located beneath the tray, movable from a first position within the housing to a second position exterior of the housing, divided into two semi-cylindrical form components, and hinged along its axial length between the semi-cylindrical form components to permit opening and closing.Type: GrantFiled: May 30, 1978Date of Patent: December 25, 1979Assignee: Pyro Dynamics, Ltd.Inventor: Bernard Wachter

Patent number: 4010763Abstract: An adjustable apparatus can cut V-shaped segments of different dimensions from continuous sheets so that the V-shaped segments of different dimensions are suitable for application as wrappers to double cigar bunches of different dimensions. The apparatus can also cut the two tails of each V-shaped segment into flag-shaped configurations which will permit the smooth application of the two tails to the opposite ends of double cigar bunches having rounded ends.Type: GrantFiled: December 18, 1975Date of Patent: March 8, 1977Assignee: Culbro CorporationInventor: Hans C.
