! BACKGROUND OF THE INVENTION
,~ This invention relates to an improved cigarette tipping
l'material and more particularly relates to a cigarette tipping
O limaterial having a non-lipsticking coating on preselected areas
jlthereof.
,¦ In the manufacturing of cigarettes it is common practice~
to apply a coating on the tipping material of the cigarettes to
ilreduce or prevent lipsticking; that is, to `prevent the tendency
l¦of the wrapping around a cigarette filter which comes in contac~
with the smoker's lips to adhere thereto. Presently, there is
known in the art several different methods for coating the tipping !
of ci~arettes to prevent or at least reduce the sticking of
Ijcigarette wrapping or materia~ to the smoker's lips during use.
0 l,British Patent No. 328,147 relates to a cigarette having a tip
'¦or end that prevents sticking to the lips wherein the coating
~is applied to preselected surfaces on the tip. U.S. Patent
No. 288,151 teaches a cigarette wrapper having preselected areas
llwith the coating thereon which is applied in a form of a design.
S IlU.S. Patent No. 2,033,791 teaches a water-proof tip for cigarettes,
which is "lip-proof" and only preselected portions of the tobacco
llpaper are coated and this coating is applied for strengthening
jjthe paper. Other patents ~hich teach coating of the wrapper

S~I~ARY OF THE I~TV~NTION
! In the present invention, it is recognized that it is
1¦ desirable to provide a cigarette tipping material with non-
¦ lipsticking properties. Furthermore, it is recognized that
¦¦it is desirable to provide a cigarette tipping material havin~
I! air ventilating perforations in the tipping material for mixing
j~of air with the smoke stream at the filter end of a cigarette.
¦I The present invention advantageously provides a
¦cigarette tipping material having non-lipsticking properties.
The present invention further provides cigarette tipping material
,which has non-lipsticking properties and is also provided
jwith air ventilating perforations therein. E~en further, the
¦present invention provides a method of making cigarette tipping
material having a coating in preselected areas thereon with
non-lipsticking properties and perforations in non-coated
areas wherein the method includes means that eliminates clogging
of the perforations with coating material and eliminates
build-up or other problems with the means for addin6 the per-
¦forations thereby reducing downtime, machine clean-up and
~provides for a consistent perforated product.
¦ ~arious other features of the present invention will
become obvious to those s~illed in the art upon reading the
~5 disclosure set forth hereinafter.
More particularly, the present invention provides a
cigarette tipping material comprisin~:

a sheet of tipping material;
I a coating having non-lipsticking properties covering
¦preselected areas of the sheet; and,
! perforations in the sheet, said perforations being
located in areas not covered by said coating.
It is to ~e understood that the description of the
examples of the present invention given hereinafter are not
¦by way of limitation and various modifications within the
~scope of the present invention will occur to those skilled
~0 ¦in the art upon reading the disclosure set forth hereinafter.
BRIEF DESCRIPTION OF THE DRAWING
Referring to the drawing:
Figure 1 is a perspective view of a sheet of cigarette
tipping material of the present invention;
Figure 2 is a perspective view of a cigarette using
the tipping material of Figure l; and,
Figure 3 is a schematic view, in perspective, of one
preferred embodiment of making the tipping material of Figure 1.
DESCRIPTION OF THE PREFERRED EMBODI~NT OF THE INYENTION
In Figure 1 a sheet of tipping material 2 is provided
with preselected are~as 4 coated with non-lipsticking or lip
releasing type material thereon. These coatings with the non-
¦lipsticking properties include ethyl cellulose, nitrocellulose,
or any other well known agent used for preventing the sticking
of a smoker's lip to a cigarette. The coating may be applied
along various configurations and as shown is applied alon~
spaced parallel straigllt lines running the length of the paper
an~ in use, as shown in Figure 2, extends around the filter 6
of a cigarette 5. The uncoated areas of the tipping paper is
1 157733
~1
also provided with spaced parallel straight lines of perfora-
tions 8 which also encircle a filter 6 (as shown in Figure 2)
thereby allowing air into the smoke stream as it passes through
the filter 6 when in use.
In a preferred method of making tipping material
of the present invention, as shown in Figure 3, unprinted
tipping paper 10 is fed to a pair of synchronized rollers 12
and 14. ~oller 12 is a pressure roller and roller 14 is a
gravure printing roller having preselected engraved areas
therein, the engraved areas being identified by the numerals
16a, 16b and 16c so~~that as the roller 14 passes through a
reservoir 20 having a coating 22 therein the coating does
not transfer or adhere to the unengraved areas of the roller
Igravure cylinder. Thus, as the sheet 10 passes between the
¦jrollers 12 and 14, coating is applied to the underside of
¦¦the tipping paper in a preselected pattern. The tipping paper
¦10 leaving the coating step of the preparation is then fed
into a drier for drying the coating. The drier includes
iair blower 40 and a fire-box 4~ for heating air and directin~
¦same to the paper 10 passing therethrough. It is realized
¦that the drier as shown is for illustrative purposes only as
¦any means for drying known in the art may be utilized. Paper 10
is then fed into a pair of synchronized rol~s 24 and 26. The
roller 26 is provided with a pair of parallel rings 18a and
2~ 18b wherein the rings are provided with a plurality of pins
28 which, upon rotation of the cooperating rollers 24 and 26,
perforate the tipping paper.~ It is noted that the rings 18a
and 18b are in alignment with the unengraved portions of the
cylinder so that when the tipping paper passes ~etween the
cooperating rollers 24 and 26 the pins 28 perforatc the tippin~ '~

paper in the uncoated area of the paper 10. ~he product
leaving the rollers 24 and 26 shows the uncoated portion
having rows of apertures therein, identifiable by the numerals
18c and l~d, and a coated area 30. The tipping paper is then
ready for use with a cigarette filter.
It is realized that the tipping material may be per-
forated prior to coating and that various other changes may
¦be made to the specific embodiments shown and described without
departing from the principles and spirit of the preSeAt invention.
