Definitions
- This invention is concerned with the manufacture of double-tipped cigarette units, each comprising a double-length tobacco rod to each end of which a filter portidn is secured; such units will, for convenience be referred to as "double cigarette units".
- double cigarette units In accordance with the invention described in our British patent specification No. 1584551 (and corresponding German Offenlegungsschrift 2716391), such cigarette units may be conveyed to a packing machine at which the units are cut through the middle to form individual filter-tipped cigarettes. In that way, the tobacco is positively retained until just prior to packing of the cigarettes.
- such double-length cigarette units are made by forming a continuous tobacco-filled rod (in any known manner), cutting the rod at regular intervals to form double-length tobacco rods, spacing the tobacco rods apart while they are moving longitudinally, inserting double-length filter portions between successive rods, applying strips of uniting material at regular intervals so that each strip extends along the entire length of a double-filter portion and overlap the adjacent ends of the adjacent tobacco rods, wrapping the strips around the tobacco and filter portions to form a continuous rod comprising alternate double tobacco and filter portions, and then cutting the continuous rod through the middle of each double-filter portion to form the desired double-cigarette units.
- the invention avoids the production of "ring- tipped” cigarettes, as described in the above-mentioned Patent Application.
- this invention enables conventional filter-tipped cigarettes to be made, with ihe "cork” or other uniting web surrounding the entire filter portion instead of only the end adjacent the tobacco rod.
- tobacco in this content is intended to include any smokable material or mixture of such materials, including possibly reconstituted tobacco or synthetic tobacco or both.
- Figure 1 shows a basic cigarette making machine comprising a chimney 10 up which tobacco is showered, by means of an upward-moving air stream, onto a suction band 11 to form a continuous cigarette filler stream 12.
- the filler stream is trimmed by a trimming device 13 and is then deposited on a continuous wrapper web 14 which is wrapped around the filler stream in a rod-forming section 15 to form a continuous cigarette rod.
- Further details of the machine may be similar to the Molins Mark 8 or Mark 9 cigarette making machine, though other completely different forms of machine may be used for this purpose.
- the continuous cigarette rod is cut at regular intervals by a cutting device 16 to form double-length tobacco rods 16A. These rods are then spaced apart, for example by means of a faster moving suction band 17, too produce gaps between which double-length filter portions 18A are fed by a device 18.
- This device 18 may be as described in our British Patent Specification No. 1471534 (and corresponding German Offenlegungsschrift 2434449).
- the stream of alternate cigarette and filter rods is then conveyed forward by a band 17A and is closed up so as to eliminate the gaps between successive rods.
- the stream of rods is then fed onto an air-pervious tape 19 which carries on its outer surface spaced web portions 20 with the aid of suction applied through the tape 19 from a suction chamber 21.
- Each web portion 20 is applied over one double-filter rod and overlaps onto the ends of the adjacent tobacco rods.
- the web 19 moves along a bed member 22 which progressively bends the tape 19 and consequently also the web portion 20 into a U-section, after which the upper edges of the web portions 20 are bent further around the rod by a device 23 so as to be wrapped completely around the rods.
- the composite rod which is thus formed is then cut at regular intervals by a cutting device 24 to form double-cigarette units 24A of the construction already described. These cigarette units are then conveyed to a packing machine at which they are cut through the middle to form individual filter-tipped cigarettes.
- the device 23 which completes the wrapping of the web portions 20 around the rods may, for example, comprise a pair of rotary tucker members each having one or more web-engaging parts which fold over the edges of successive webs when the webs are aligned with the device 22.
- a pair of rotary tucker members each having one or more web-engaging parts which fold over the edges of successive webs when the webs are aligned with the device 22.
- Figure 2 shows a modified arrangement for feeding strips of uniting material onto the rods.
- a continuous web 25 of uniting material e.g. "cork”
- rollers 26 towards a drum 27 which rotates with a peripheral speed greater than the speed of the web.
- a cutting device 28 cooperates with the drum 27 to cut the web at regular intervals, and the strips 25A cut off the web are carried further on the drum through the action of suction ports in the surface of the drum in a manner similar to that used in our PA8 filter attachment machine (some details of which are described in our U.S. patent 4,044,779); suction in those ports is timed to cease when each strip is applied to the respective rods.
- Folding of the strips around the rods is started, as soon as possible thereafter, by a tape 29 acted somewhat like a garniture tape in a conventional cigarette making machine.
- the completion of folding may be achieved by means of one or more rotary tuckers or by one or more stationary folders or by a combination of both.
- Adhesive is preferably applied to the outer, surface of the web 25, by means of an applicator roller device 30, before the web reaches the drum 27.
- timed patches of adhesive may be applied to the strips cut from the web while they are on the drum 27.
- the timing of the delivery of the strips to the rods may be controlled as follows.
- An optical device 31 detects and signals the arrival of the filters, and the signals are used to control the timing or phasing of a motor (not shown) during the strip-feeding parts.
- the motor may be one of the low-inertia "printed circuit" motors, which can be finely adjusted as to its speed.
