Abstract
Filter cigarettes are produced by uniting tobacco sections (12, 122) and filter portions (21, 120) with a wrapper (28, 124) which carries a relatively thick circumferential bead (126) of adhesive or other filler material to provide an effective seal around the cigarette. The cigarettes may be assembled on parallel assembly lines (16, 18) supplied with tobacco sections from a common maker line (10) by a carrier conveyor (14) arranged to supply alternate sections to different assembly lines disposed at 90.degree. to the maker line.
Claims28
Apparatus for conveying rod-like articles of the tobacco industry, particularly in the manufacture of filter cigarettes, comprising means for conveying rod-like articles in axially adjacent positions, means for delivering a wrapper to a plurality of said articles to be united, and wrapping means for feeding said wrapper around at least a portion of each of said plurality of articles to unite said articles, including means for locating a flowable filler material between said wrapper and each of said plurality of articles in the form of at least one relatively thick discrete band positioned about each of said plurality of articles and means for pressing said wrapper onto and around said articles to seal any space between said wrapper and each of said plurality of articles, whereby a composite rod, comprising said plurality of articles, is formed having a wrapper sealingly surrounding at least a portion of each of said articles.
Apparatus for conveying rod-like articles of the tobacco industry, particularly in the manufacture of filter cigarettes, comprising means for conveying a stream of tobacco sections in an axial direction along a first conveyor path, means for conveying tobacco sections in an axial direction along second and third conveyor paths on which paths said sections are intercalated with filter portions, and means for receiving selected tobacco sections from said first conveyor path and for transferring them to said second or said third conveyor path, said second and third conveyor paths being disposed at an angle to said first conveyor path and said selected tobacco sections being conveyed substantially in an axial direction between said first and said second or said third path, said receiving and transferring means comprising further conveyor means with a plurality of first carriers and a plurality of second carriers, respectively, having a common path portion adjacent said first conveyor path and separate path portions adjacent said second and third conveyor paths respectively, and transfer means for transferring tobacco sections from said first conveyor path to said first and second carriers in said common path portion and for transferring tobacco sections from said first carriers in one of said separate path portions to said second conveyor path and from said second carriers in the other of said separate path portions to said third conveyor path.
Apparatus for conveying rod-like articles of the tobacco industry, particularly in the manufacture of filter cigarettes, comprising first and second endless conveyors having respective carriers for rod-like articles which have a common path portion and which each have path portions which are not common with any path portion of the carriers of the other conveyor, including means for transferring rod-like articles to the carriers of either conveyor in said common path portion, and means for releasing said articles on said path portions which are not common.
Apparatus for conveying rod-like articles of the tobacco industry, particularly in the manufacture of filter cigarettes, comprising an endless conveyor including at least one carrier for rod-like articles, guide means defining a concave path portion for the conveyor, suction means for maintaining the conveyor in contact with the guide means against tension in the conveyor and also for retaining a rod-like article on said carrier, and air pressure means for supplying air under pressure to reduce friction between the guide means and the conveyor.
Apparatus for conveying rod-like articles of the tobacco industry, particularly in the manufacture of filter cigarettes, comprising means for conveying rod-like articles in axially adjacent positions, means for delivering a wrapper to a plurality of said articles to be united, and wrapping means for feeding said wrapper around at least a portion of said plurality of articles to unite said articles, including means for locating a flowable filler material between said wrapper and each of said plurality of articles in the form of at least one relatively thick discrete band positioned about each of said plurality of articles and means for pressing said wrapper onto and around said articles to seal any space between said wrapper and at least one of said articles, whereby a composite rod, comprising said plurality of articles, is formed having a wrapper sealingly surrounding at least a portion of each of said articles, said locating means being arranged to apply said flowable material to form said at least one band such that, in said composite rod, an annular space is formed between said wrapper and said at least one of said articles, whereby air flow over the surface of at least one article in said space is possible.
