Abstract

The effect of spiral-wrapping of a tobacco rod is obtained by providing a wrap material (1) having edge portions (3) which are angled to an edge (4) which is to be arranged axially of the tobacco rod when the material is wrapped cylindrically around the tobacco. Discontinuities (5) between inclined edge portions (3) are preferred positions for the severing of rods wrapped with the material, into cigarette lengths. Methods and apparatus are disclosed for wrapping or overwrapping with this material to form the tobacco rod.

Description

METHOD AND APPARATUS FOR WRAPPING A ROD
OF SMOKING MATERIAL
The present invention relates to a method and
apparatus for manufacturing a rod of tobacco or other
smoking material enclosed by a wrap (hereinafter "tobacco
rod") . It is especially concerned with tobacco rods
having a spiral-effect outer wrap and a method and
apparatus for producing these.
Cigarettes are commonly wrapped in paper by
placing a line of tobacco along a paper strip, in parallel
alignment with the edges of the strip, enclosing the
smoking material in the paper strip by bringing its edges
together and sealing them together to form a rod having a
longitudinal seam in its paper. Cigar-style products are
commonly provided with a spiral wrap of tobacco leaves or
reconstituted tobacco material. The machinery required to
spiral wrap a tobacco rod is more complex than that used
for parallel wrapping because either the rod, or the outer
wrap material must be rotated relative to the axis of the
rod to achieve the spiral .
One known method of providing a spiral wrap to a
cigar style product is to roll a double length tobacco rod onto a chevron-shaped piece of outer wrap material to give
a double length spirally wrapped tobacco rod with a left
hand and a right hand spiral. This is then cut in half to
give two cigars.
A second known method to produce a spiral outer
wrap rotates smoking material rods, pre-wrapped in a
binder or inner wrap, about their longitudinal axis
between two endless belts running in opposite directions.
The rod is set at an angle to the belts so that as it
spins, it also moves forward along its axis. A web of
outer wrap material is fed, parallel to the belts, to wrap
around the rod as it advances. The spirally wrapped rod
is then cut to the required length.
Another known method of spirally wrapping a
smoking material rod involves passing the rod through the
middle of a bobbin of outer wrap material, at an angle to
the axis of the bobbin, and rotating the bobbin around the
rod. The rod is spirally wrapped by outer wrap material
taken from the bobbin. A problem with this method is that
control is complicated by the changing inertia and speed
of the bobbin as the wrap material unwinds from it .
An object of the present invention is to achieve
a non-parallel wrap effect in a simpler and more efficient way .
According to a first aspect, the present
invention provides a method of wrapping a rod of smoking
material to give a non-parallel wrapped effect, which
includes
wrapping the rod in a parallel wrap binder,
guiding at least one extension, integral with or attached to the binder and having at least one edge at an
angle to the axis of the rod to overlie the binder on the
surface of the rod, so that the inclined edge gives a non-
parallel line,
securing said at least one extension to conform
to the binder on the rod,
and separating the wrapped rod into discrete
lengths.
In preferred embodiments, a plurality of
extensions each have at least one inclined edge, there being a discontinuity between inclined edges of adjacent extensions. In such embodiments, the wrapped rod may be
divided into discrete lengths at the discontinuities.
When the inclined edge is straight, a spiral wrap effect
is obtained.
Since the guiding is essentially a wiping motion it can be done by static parts (by virtue of the axial
motion of the rod through the machine) ,- even if a rotating
wiper is provided to cause the extension to conform it
does not have to contain or feed sheet material.
When the extensions are non-integral, they may
be attached to the binder before, during or after the
formation of the parallel wrap.
In one such method, discrete lengths of outer
wrap material are severed from a web of outer wrap
material and affixed to a binder pre-wrapping a rod of
smoking material, to form the extensions which project
from the rod at an angle to its longitudinal axis. The
projecting sheets are then guided around the rod to
provide the wrap effect.
In a second aspect, the present invention
provides an apparatus for wrapping a rod of smoking
material comprising means for wrapping the rod in a
parallel-wrap binder and means for guiding around the rod
at least one extension of wrap material projecting from
the parallel wrapped rod and having at least one edge
inclined at an angle to its longitudinal axis.
In one embodiment, the means for guiding
comprise a paddle rotatable about the rod to guide the projecting sheets of outer wrap material around the rod.
As the guide means rotate around the axis of the rod, the rod moves forward along its longitudinal axis. In this
manner, the projecting extensions of outer wrap material
may be guided into a spiral formation around the rod.
In an alternative embodiment, the means for
guiding comprise a plough turner having a trough or tube
through which a tobacco rod may be passed, the trough or
tube having a spiral wall, edge or slot to guide the at
least one edge of a projecting extension around the rod as
the rod advances.
The apparatus according to the invention may be
provided by adapting known cigarette or cigar wrapping
machinery, or may be provided as a separate machine at the
end or in the middle of a conventional cigar or cigarette
manufacturing machine.
Glue may be applied to the projecting sheets of outer wrap material before or during guiding to form the
spiral effect wrap. In a third aspect, the present invention
provides a web of wrap material for wrapping a rod of
smoking material comprising a parallel wrap binder and at least one extension from a parallel binder forming portion thereof, the extension having at least one inclined edge.
Where there are a plurality of extensions, there
may be discontinuities between the inclined edges of
adjacent extensions.
The extensions may be integral with the binder,
or affixed thereto.

the middle of a conventional cigarette manufacturing
machine.
In the subject invention, a spiral-effect outer
wrap may be provided for a pre-formed tobacco (or other
smoking material) rod which already has a wrap of binder
material, or a rod may be formed and wrapped in one
process. In both cases, a conventional cigarette wrapping
machine can be adapted to provide the spiral wrap. Figs.
1 and 2 show two forms of wrap which may be used when the
rod is formed and wrapped in one action. A sheet material
used for cigarette wrapping is in the form of a web 1,1'
having a binder region 2,24 having a free edge 4 and a
parallel notional edge 6, thus being equivalent to a
conventional parallel-sided web of cigarette wrap paper
and forming a parallel wrap about the smoking material.
However, extending therefrom are extensions 8 (which in
Fig. 2 are provided by separate sheets 26 attached to the
binder region 24) having an inclined straight edge 3, angled away from the parallel binder edges 4,6. Between
successive extensions 8 are saw-toothed discontinuities 5,
where one inclined edge 3 stops and the next begins. When
the extensions 8 are guided around the rod, the inclined
edges 3 form a spiral effect which stops at the
discontinuity 5. The rod may then be divided into
lengths, preferably at the discontinuities, each length,
having an inner parallel wrap provided by the binder
region 2,24 and an outer, spiral effect wrap provided by
the extensions 8. The length and angle of the edge 3 may
be such as to provide one, or more than one, helical turn
in the length of each finished separated rod.
When the webs 1 of wrap material are used in a
combined rod forming and wrapping process, tobacco or
other smoking material 7 is deposited (see Fig. 5) on the
binder portion 2,24 of the wrap material 1 of Fig. 1 or
Fig. 2, which is supported and transported from a reel of
wrap material (not shown) by a garniture tape 10 supported
on two rollers 11. The wrap material is guided through a
guide trough 12 of mainly semi-cylindrical cross-section
formed in a support body 14, and the tobacco 7 is
compressed within the trough 12 by a concave pressure
finger 16 (Figs. 4-7) to form the tobacco rod 17. As the wrap material 1 and compressed tobacco 7 pass along the
trough 12, guiding wall elements 18,20 gradually raise the
longitudinal edges of the wrap material (Figs. 6-8) to
enclose the tobacco, as in a conventional cigarette making
machine. Glue is applied by a nozzle 23 (Fig. 9) along
the parallel glue line 6 of the binder portion 2,24 of the
wrap material 1 adjacent the projections 8 and guide means
22 hold the extensions 8 away from the tobacco rod 17.
The guide walls 18,20,30 fold the binding portion 2,24 of
the longitudinal wrap 1 to enclose the tobacco rod 17, the
free edge 4 of the wrap material 1 being secured with the
glue applied adjacent 6 the extensions 8. The glue is set
by application of a heat bar 32 (Fig. 11) .
At this stage, in a conventional cigarette
manufacturing machine, the tobacco rods would be cut into
lengths suitable for the cigarette or cigar product. They
would then be transported to tipping and packaging
machines as applicable. However, in the methods of the
invention, this is preceded by the need to guide the
projecting outer wrap sheets around the formed tobacco
rod.
After the binder glue has set, the extensions 8
are guided around the formed rod 17 and secured there with glue which can be applied either just before the guidance
or at an earlier stage.
Preferably, non-moving parts of the apparatus
guide the extensions 8 as the tobacco rod 17, enclosed by
the binding portion 2,24 of the wrap 1, moves
longitudinally through the wrapping apparatus supported by
the garniture tape 4. One way in which this can be
achieved is by plough turning. In this process the
tobacco rod 17 moves along a guide channel 40 of a plough
turner (Figs. 12-17) one wall 42 of which defines a spiral
and which guides the extensions 8 spirally around the rod
17. Glue may be applied to the extensions 8 as the rod 17
moves along the plough turning guide channel 40 or before
the rod 17 enters the plough turner.
Alternative methods of guiding the extensions
around the rod include using garniture tapes or external
winders. One example of an external winder is indicated
by reference numeral 100 in Fig. 18. This consists of a
blade 102 having a portion parallel to the tobacco rod 17
and a portion angled away therefrom, the blade 102 being
rotationally mounted upon a drive unit 104 through which
the tobacco rod 17 passes. Rotation of the blade 102
about the tobacco rod 17 causes the projecting sheets 8 of outer wrap material to be wrapped around the rod, as the
rod 17 passes through the drive unit 104.
Fig. 18 illustrates apparatus for carrying out
the method in which separate strips 28 of outer wrap
material are attached to a pre-made rod 17 as shown in
Fig. 3 and then wound around the rod. The pre-made rod is
enclosed in a binder or inner wrap before the strips of
outer wrap material are attached. This may be done in a
conventional cigarette making machine.
As the wrapped tobacco rod 17 exits guide trough
12 of a conventional cigarette making machine, it passes
under a suction drum 110 which carries pre-cut sheets, or
"flags" 28 of outer wrap material. The flags 28 are
removed from the suction drum 110 by garniture tape 112
which passes around the drum and under inverted guide
trough 113. This so-called inverted garniture tape
transfers the flags from the drum to the moving tobacco
rod.
The flags are cut from a web of outer wrap
material 115 drawn by drive units 116 from a bobbin 114.
Glue is applied to the web 115 by gluing rollers 118 and
the web 115 is fed towards the suction drum 110 at an
angle to its axis, passing beneath cutting roller 120, mounted parallel to the suction drum 110, which cuts
rhomboid flags from the web 115. Rotary clamp 122 presses
each severed flag 28 onto the garniture tape and suction
drum 110. Suction from within the drum 110 acts through
perforations in the drum's circumferential surface to hold
the flags 28 in place. As the flags 28 come into contact
with the tobacco rod 17 beneath the suction drum 110, they
are attached by the previously applied glue to the rod 17
to form extensions of the binder. The flags 28 are held
in place and curved around the rod as the inverted
garniture tape passes through the guide trough 113, so
that they project generally downward from the rod 17 as
they approach the external winder 100, the action of which
is described above.
The spirally wrapped tobacco rod passes to
cutting drum 124 and is cut at the discontinuities 5'
between the extensions, into the correct lengths 125 for
the desired cigarette or cigar product. Each length 125
has a spiral effect outer wrap provided by the inclined
straight edge 3 of a single projecting flag 8. The
lengths 125 are then passed through a series of rollers
126,128 to an end trimming roller 130 and blade 131 which
may be as found in a conventional cigarette manufacturing machine. The trimmed lengths may then pass to tipping or packaging machinery, as required.
Further winding means such as the plough turner described above may be fitted between the inverted
garniture 112,113 and the external winder 100.
The edges 3 need not be straight, so that wrapping effects other than spiral, e.g. a wavy edge, could be obtained if desired.
