Abstract
Abstract A roller with a friction surface is positioned adjacent the cigarette transfer drum and is driven by a transmission off the transfer drum drive to rotate at a greater speed than the transfer drum. The greater speed of the roller allows the roller to positively roll the cigarettes on the drum prior to ejection in order to seal the free end of the mouthpiece paper on itself while also imparting a roundness to the cigarette. The greater speed of the roller also serves to positively eject the cigarettes into a chute below the transfer drum.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
103 words
In a cigarette transfer assembly, a rotatable transfer drum for moving a continuous stream of cigarettes from a receiving position to an ejection position, said stream being composed of individually spaced apart cigarettes, means for retaining said stream of cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection.
Claim 2
Dependent Claim
103 words
In a cigarette transfer assembly, a rotatable transfer drum for moving a continuous stream of cigarettes from a receiving position to an ejection position, said stream being composed of individually spaced apart cigarettes, means for retaining said stream of cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection.
Claim 3
Dependent Claim
103 words
In a cigarette transfer assembly, a rotatable transfer drum for moving a continuous stream of cigarettes from a receiving position to an ejection position, said stream being composed of individually spaced apart cigarettes, means for retaining said stream of cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection.
Claim 4
Dependent Claim
103 words
In a cigarette transfer assembly, a rotatable transfer drum for moving a continuous stream of cigarettes from a receiving position to an ejection position, said stream being composed of individually spaced apart cigarettes, means for retaining said stream of cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection.
Claim 5
Dependent Claim
23 words
In a cigarette transfer assembly as set forth in claim 1, said friction surface being a gum rubber strip secured to said roller.
Claim 6
Dependent Claim
35 words
In a cigarette transfer assembly as set forth in claim 1 wherein said roller is spaced from said drum to form a nip slightly less than a predetermined diameter of a cigarette in said stream.
Claim 7
Dependent Claim
37 words
In a cigarette transfer assembly as set forth in claim 1 wherein said means includes a pair of endless belts passing over said drum between said positions to hold the cigarettes of said stream on said drum.
Claim 8
Dependent Claim
57 words
In a cigarette transfer assembly as set forth in claim 1 wherein said roller rotates at a speed relative to said drum to roll each cigarette through one revolution of a cigarette prior to ejection to seal a strip of self-adhering wrapping paper of each cigarette to itself and to eject each cigarette at an accelerated speed.
Claim 9
Dependent Claim
101 words
In a cigarette transfer assembly, a rotatable transfer drum for moving cigarettes from a receiving position to an ejection position; means for retaining said cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection under a pressure sufficient to impart a round cross-sectional shape to each cigarette.
Claim 10
Dependent Claim
101 words
In a cigarette transfer assembly, a rotatable transfer drum for moving cigarettes from a receiving position to an ejection position; means for retaining said cigarettes on said transfer drum between said positions; a roller positioned adjacent said drum at said ejection position, said roller having a friction surface thereon for engaging the cigarettes of said stream; and means for rotating said roller at a greater speed of rotation than said drum to cause each cigarette in said ejection position to be rolled on said drum prior to ejection under a pressure sufficient to impart a round cross-sectional shape to each cigarette.
Claim 11
Dependent Claim
35 words
In a cigarette transfer assembly as set forth in claim 6 wherein said roller is spaced from said drum to form a nip substantially equal to a preset diameter of a cigarette in said stream.
Claim 12
Dependent Claim
57 words
In a cigarette transfer assembly as set forth in claim 6 wherein said roller rotates at a speed relative to said drum to roll each cigarette through one circumference on said roller prior to ejection to seal a strip of self-adhering wrapping paper of each cigarette to itself and to eject each cigarette at an accelerated speed.
Claim 13
Dependent Claim
91 words
In combination, a rotatable drum for moving cigarettes from a receiving position to an ejection position, a roller positioned adjacent said drum at said ejection position, said roller having a surface for engaging a cigarette at said ejection position, and means for rotating said roller at a greater speed of rotation than said drum and in an opposite sense of direction to cause a cigarette in said ejection position to be rolled on said drum prior to ejection under a pressure sufficient to impart a round cross-sectional shape to each cigarette.
Claim 14
Dependent Claim
91 words
In combination, a rotatable drum for moving cigarettes from a receiving position to an ejection position, a roller positioned adjacent said drum at said ejection position, said roller having a surface for engaging a cigarette at said ejection position, and means for rotating said roller at a greater speed of rotation than said drum and in an opposite sense of direction to cause a cigarette in said ejection position to be rolled on said drum prior to ejection under a pressure sufficient to impart a round cross-sectional shape to each cigarette.
