Abstract
Abstract A cigarette packing machine of the type where a hollow packet or wrapper presenting an open head side and a closed bottom side is formed around a tubular mandrel or arbor, and a pushing plunger is provided for ejecting a group of cigarettes previously inserted at the interior of said arbor in the direction of the closed bottom side of the wrapper, further comprises a slip-off device for slipping the hollow wrapper off the arbor concurrently with the displacement of the cigarette group promoted by the pushing plunger. The slip-off device consists of a rotating friction roller arranged towards and away from said arbor, so as to cause the engagement of its peripheral friction surface with the wrapper formed on the arbor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A cigarette packing machine of the type where a hollow packet or wrapper presenting an open head side and a closed bottom side is formed around a tubular mandrel or arbor, the packing machine including plunger means for ejecting a group of cigarettes previously inserted at the interior of said arbor in the direction of the closed bottom side of the wrapper, and drive means to reciprocate said plunger means through said arbor, wherein the improvement comprises a slip-off device for slipping the said hollow packet or wrapper off the said arbor concurrently with the displacement of the cigarette group promoted by the said plunger means, and drive means connected for operating said slip-off device synchronously with said plunger drive means so that the cigarette group is maintained out of contact with said closed bottom side of said wrapper during at least a substantial portion of the slipping movement of said wrapper off of said arbor.
Claim 2
Dependent Claim

A cigarette packing machine of the type where a hollow packet or wrapper presenting an open head side and a closed bottom side is formed around a tubular mandrel or arbor, the packing machine including plunger means for ejecting a group of cigarettes previously inserted at the interior of said arbor in the direction of the closed bottom side of the wrapper, and drive means to reciprocate said plunger means through said arbor, wherein the improvement comprises a slip-off device for slipping the said hollow packet or wrapper off the said arbor concurrently with the displacement of the cigarette group promoted by the said plunger means, and drive means connected for operating said slip-off device synchronously with said plunger drive means so that the cigarette group is maintained out of contact with said closed bottom side of said wrapper during at least a substantial portion of the slipping movement of said wrapper off of said arbor.
Claim 3
Dependent Claim
66 words
A cigarette packing machine according to claim 1, in which the slip-off device consists of a friction roller operatively arranged in proximity of the arbor, said friction roller being driven into rotation, means being provided for moving said friction roller laterally towards and away from the said arbor so as to cause the engagement of its peripheral friction surface with the wrapper formed on the arbor.
Claim 4
Dependent Claim
27 words
A cigarette packing machine according to claim 1, in which the slip-off device consists of a revolving sector provided on its arcuate periphery with a friction surface.
Claim 5
Dependent Claim
54 words
A cigarette packing machine according to claim 1, in which the slip-off device consists of a friction finger movable to and fro in the longitudinal direction of the arbor, means being provided for moving said friction finger laterally towards and away from said arbor so as to engage the wrapper formed on the arbor.
Claim 6
Dependent Claim
43 words
A cigarette packing machine according to claim 1, in which the slip-off device consists of a suction head movable to and fro in the longitudinal direction of the arbor and acting on the outer surface of the closed bottom side of the wrapper.
Claim 7
Dependent Claim
68 words
A cigarette packing machine according to claim 5, which further presents an additional slip-off device consisting of a friction roller operatively arranged in proximity of the arbor, said friction roller being driven into rotation, means being provided for moving said friction roller laterally towards and away from the said arbor so as to cause the engagement of its peripheral friction surface with the wrapper formed on the arbor.
