Patent number: 7640935Abstract: Cigarette filters are supplied to the infeed portion (1) of a filter tip attachment machine by a unit (2) comprising rollers (11) which divert the filters (3) into an upstream hopper (8), and a channel (9) carrying the filters (3) from the upstream hopper (8) to a downstream hopper (4) where they are released to the infeed portion (1) of the machine. Located between the infeed rollers (11) and the feed channel (9) is a variable volume storage buffer (16) with a movable wall (28) attached to the top branch (23) of a conveyor belt (24); the Belt is driven by a motor (27) interlocked to sensors (31) which monitor and control the level of the mass of filters (3) occupying the upstream hopper (8), so that the size and capacity of the buffer (16) can be adjusted to accommodate fluctuations in the flow of filters through the hopper (8).Type: GrantFiled: March 11, 2004Date of Patent: January 5, 2010Assignee: G.D S.p.A.Inventors: Fiorenzo Draghetti, Salvatore Rizzoli

Patent number: 7040325Abstract: Adhesive-coated bands of paper, tipping paper or plastic foil are convoluted around discrete one-piece or composite rod-shaped articles, such as coaxial plain cigarettes and filter mouthpieces, during travel through a rolling zone bounded by a pair of surfaces at least one of which moves relative to the other. The inlet of the rolling zone receives articles, each of which carries a non-convoluted band, from a conveyor which forms part of a pressing device operative immediately ahead of the inlet of the rolling zone and serving to press successively delivered bands against the respective articles and to effect an at least slight flattening of the articles immediately prior to entry into the rolling zone. The width of the path for the articles increases at the outlet of the rolling zone or immediately downstream of such outlet.Type: GrantFiled: March 13, 2002Date of Patent: May 9, 2006Assignee: Hauni Maschinenbau AktiengesellschaftInventors: Manfred Dombek, Berthold Maiwald

Patent number: 6526985Abstract: Successive cigarettes of a series of cigarettes, such as filter cigarettes, are transported sideways in the axially parallel peripheral flutes of a rotary drum-shaped conveyor to the inlet(s) of a straight or V-shaped rolling channel or of two successive straight channels defined by the rolling surface(s) of one or two stationary block-shaped rolling members and the external surface of an endless belt trained over several rollers and being at least partially confined in a recess or groove of the conveyor in such a way that the surface(s) of the rolling member(s) cooperate with the surface of the belt to roll successive cigarettes in the channel or channels about their longitudinal axes while one or more beams issuing from one or more lasers or other radiation source(s) impinge upon the wrappers of the cigarettes rolling in the channel or channels.Type: GrantFiled: May 11, 2001Date of Patent: March 4, 2003Assignee: Hauni Maschinenbau AGInventor: Manfred Dombek

Patent number: 6390099Abstract: An apparatus, such as a filter tipping machine, wherein groups of coaxial rod-shaped articles are connected to each other end-to-end by adhesive-coated uniting strips or bands, employs two endless conveyor belts having parallel stretches defining an elongated rolling channel and moving in the same direction but at different speeds. A first rotary drum-shaped conveyor is employed to deliver successive groups, each of which can carry a uniting band, sideways into the inlet of the channel wherein the groups are caused to roll and the uniting bands are convoluted around them. A second rotary drum-shaped conveyor receives successive groups of interconnected rod-shaped articles from the outlet of the rolling channel and delivers them to a processing station, such as a severing or packing station, or to a magazine. One of the endless conveyor belts is trained over the drum-shaped conveyors.Type: GrantFiled: December 14, 1999Date of Patent: May 21, 2002Assignee: Hauni Maschinenabau AGInventor: Manfred Dombek

Patent number: 6152145Abstract: For the continuous production of the cigarette rod (10), the strip-like outer wrapper (12) and a tobacco strand (11) are provided on a forming belt (15) and conveyed, with the latter, through a rod-forming unit (13). Located within the latter is a forming bed (19) which, during transportation, deforms the forming belt (15) along with the outer wrapper (12) and the tobacco rod (11) so as to produce a cigarette rod (10). A compensating belt (21) is provided in order to avoid or reduce the friction of the forming belt on the forming bed (19), and said compensating belt circulates at reduced speed between the forming belt (15) and forming bed (19) The compensating belt (21) reduces the friction and dissipates (frictional) heat.Type: GrantFiled: May 18, 1998Date of Patent: November 28, 2000Assignee: Focke & Co. (GmbH & Co.)Inventor: Heinz Focke

Patent number: 5345954Abstract: On a cigarette manufacturing machine, a continuous cigarette rod is fed to a cutting device by a conveyor belt engaging a number of guide pulleys and a drive pulley fitted to a drive shaft; the traveling speed of the continuous rod being controlled by continuously determining the diameter of the drive pulley, for obtaining a first control signal as a function of the surface speed of the drive pulley and, consequently, as a function of the speed of the conveyor belt, and by comparing the first control signal with a second control signal as a function of the desired surface speed of the drive pulley, for obtaining an error signal for controlling the angular speed of the drive shaft.Type: GrantFiled: December 7, 1992Date of Patent: September 13, 1994Assignee: G.D Societa' Per AzioniInventors: Davide Dall'osso, Franco Ghini, Fiorenzo Draghetti

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: 4580939Abstract: A filter feed onto a fluted drum has conveyors which convey a stack-like stream of filters into a small reservoir adjacent to the drum. As they enter the reservoir, the filters are deflected upwards by a deflector plate so that the thrust by the conveyors does not produce a direct pressure of filters onto the drum. Instead, the filters are fed onto the drum by gravity after passing over the plate. A pivoted sensor plate over the reservoir controls the speed of the conveyors.Type: GrantFiled: December 8, 1983Date of Patent: April 8, 1986Assignee: Molins Machine Company Inc.Inventors: Derek H. Dyett, Clifford R. Marritt, William A. Cupp

Patent number: 4040429Abstract: A device for making "rolled" cigarettes comprising a housing containing a plate and a shaft around which an endless belt passes. Slack in the belt forms a groove or cradle between the plate and the shaft and relative movement between the plate and the shaft enables the groove or cradle to be opened and closed. When the groove or cradle is open tobacco may be inserted or a rolled cigarette removed. When the groove or cradle is closed, the belt may be moved relative to the plate by the user to roll the tobacco in the groove in paper or other sheet material.Type: GrantFiled: September 15, 1975Date of Patent: August 9, 1977Inventor: Jean R. Lacroix

Patent number: 3983761Abstract: An endless woven garniture tape or belt for cigarette making machines comprising a combination of natural, chemically modified, and synthetic fibers in a unique blend and arrangement which possesses properties that result in superior wear life performance without sacrificing other performance criteria. The warp is made from combed sak cotton fiber threads, with a multiplicity of such threads mercerized and plied together to form each warp thread. The filling threads are made up of a multifilament synthetic core wrapped with cotton fiber with a multiplicity of such wrapped threads plied together to form each filling thread. Endless belts made according to this invention have a wear life approximating three times the normal wear life of conventional belts used on cigarette making machines.Type: GrantFiled: October 28, 1975Date of Patent: October 5, 1976Assignee: Olin CorporationInventor: Emory Eugene Stewart
