Abstract
Abstract Cigarettes are made with a filler comprising an outer annulus of tobacco surrounding a core of a tobacco or other material different from that in the outer annulus. The annulus tobacco may be showered to form a layer which is then bent into a U-section to receive the core, after which further tobacco is showered on to the U-section plus core to enclose the core in tobacco. Alternatively the core material may be incorporated in the filler by pneumatically rolling a carpet of an annular of tobacco round the core.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
In apparatus for making a cigarette filler stream, comprising a. support means movable along a predetermined path, b. means for forming on said support means a carpet comprising strips lying side-by-side, said strips comprising annulus tobacco particles and core material particles, respectively, c. a trough arranged obliquely across the support means and extending obliquely downstream from the side of the support means adjacent the core material, and d. means for blowing air into the trough to roll the carpet progressively in the trough to form a filler rod, e. whereby the core material is incorporated substantially along the center of the rod.
Claim 2
Dependent Claim
102 words
In apparatus for making a cigarette filler stream, comprising a. support means movable along a predetermined path, b. means for forming on said support means a carpet comprising strips lying side-by-side, said strips comprising annulus tobacco particles and core material particles, respectively, c. a trough arranged obliquely across the support means and extending obliquely downstream from the side of the support means adjacent the core material, and d. means for blowing air into the trough to roll the carpet progressively in the trough to form a filler rod, e. whereby the core material is incorporated substantially along the center of the rod.
Claim 3
Dependent Claim
112 words
Apparatus according to claim 1 wherein said support means is elongated, has a variable width and is air-permeable and moves along a path including a curved section, said apparatus further comprising suction means to hold said carpet on said support means as it passes along said curved section, and an adjustable shutter means adjacent to the said curved section responsive to filler density detecting means to vary the proportion of the width of said support means through which air is drawn by the suction whereby the amount of particles thrown off by centrifugal force from one edge of said carpet as said support means passes along said curved section can be controlled.
Claim 4
Dependent Claim
130 words
Apparatus for making a cigarette filler stream, comprising a core of core material surrounded by an annulus of tobacco particles, the apparatus comprising a. support means movable along a predetermined path, b. means for forming on said support means a carpet of annulus tobacco particles, c. means for feeding core material on to said support means along one side of said carpet, and a trough arranged obliquely across the support means and extending obliquely downstream from the side of the support means adjacent the core material, and d. means for blowing air into the trough to roll the carpet progressively in the trough and around the core material to form a cigarette filler stream, e. whereby the core material is incorporated substantially along the center of the cigarette filler stream.
Claim 5
Dependent Claim
130 words
Apparatus for making a cigarette filler stream, comprising a core of core material surrounded by an annulus of tobacco particles, the apparatus comprising a. support means movable along a predetermined path, b. means for forming on said support means a carpet of annulus tobacco particles, c. means for feeding core material on to said support means along one side of said carpet, and a trough arranged obliquely across the support means and extending obliquely downstream from the side of the support means adjacent the core material, and d. means for blowing air into the trough to roll the carpet progressively in the trough and around the core material to form a cigarette filler stream, e. whereby the core material is incorporated substantially along the center of the cigarette filler stream.
Claim 6
Independent Claim
125 words
A method of making cigarettes and the like comprising a. forming a carpet comprising strips lying side-by-side on a moving support, said strips comprising annulus tobacco particles and core material particles, respectively, b. continuously feeding said carpet along a path past a trough extending obliquely across the carpet in a downstream direction from the side of the carpet containing the core material strip, and c. dIrecting a jet of air into said trough and carpet in a direction transverse to the longitudinal axis of said trough to progressively roll the carpet beginning at the core material strip side and ending at the annulus tobacco strip side to form a filler rod in which the core material is incorporated substantially along the center of the rod.
Claim 7
Independent Claim
125 words
A method of making cigarettes and the like comprising a. forming a carpet comprising strips lying side-by-side on a moving support, said strips comprising annulus tobacco particles and core material particles, respectively, b. continuously feeding said carpet along a path past a trough extending obliquely across the carpet in a downstream direction from the side of the carpet containing the core material strip, and c. dIrecting a jet of air into said trough and carpet in a direction transverse to the longitudinal axis of said trough to progressively roll the carpet beginning at the core material strip side and ending at the annulus tobacco strip side to form a filler rod in which the core material is incorporated substantially along the center of the rod.
Claim 8
Independent Claim
147 words
A method of making cigarettes and the like comprising a. forming a carpet comprising strips lying side-by-side on a moving support, said strips comprising annulus tobacco particles and core material particles, respectively, b. determining the density of said carpet, causing said moving support with said carpet to move along a circular path and throwing off a portion of the tobacco particles along one side of said carpet by centrifugal action while retaining the remainder of said carpet on said moving support by suction means, adjusting the width of carpet retained on said moving support by said suction means in accordance with the density of said filler rod, and c. progressively rolling the carpet beginning at the core material strip side and ending at the annulus tobacco strip side to form a filler rod in which the core material is incorporated substantially along the center of the rod.
