Abstract
Abstract A method for ensuring the cohesion of a stream of rod-shaped objects and especially cigarettes comprising a plurality of adjacent layers of the said objects and for permitting the displacement of the said stream by propulsion means which are adapted to produce action solely on one of the two outer layers comprising the step of exerting a pressure of fluid on the other outer layer in the direction of the first of the said layers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
Apparatus for conveying a plurality of piled-up layers of substantially small, lightweight, rod-shaped articles such as cigarettes in a stream in a direction transverse to their length, including: a. an infeed conveyor on one side of said stream; b. an outfeed conveyor on the same side of said stream; c. a stationary hollow casing having an exterior surface facing and alongside said stream on said one side thereof and extending between said infeed and outfeed conveyors; d. a plurality of apertures in said surface along the stream line; e. means for applying gas under pressure into said casing and through said apertures transverse to said stream; f. belt conveying means spaced from and facing said casing, said conveying means spanning the gap between the infeed and outfeed conveyors and in driving contact with one outer layer of said articles; and g. said gas impinging on the other outer layer of said articles forcing the layers toward said conveying means so that the layers are conveyed past said casing in spaced relation to the surface thereof by means solely of said belt conveying means.
Claim 2
Dependent Claim

Apparatus for conveying a plurality of piled-up layers of substantially small, lightweight, rod-shaped articles such as cigarettes in a stream in a direction transverse to their length, including: a. an infeed conveyor on one side of said stream; b. an outfeed conveyor on the same side of said stream; c. a stationary hollow casing having an exterior surface facing and alongside said stream on said one side thereof and extending between said infeed and outfeed conveyors; d. a plurality of apertures in said surface along the stream line; e. means for applying gas under pressure into said casing and through said apertures transverse to said stream; f. belt conveying means spaced from and facing said casing, said conveying means spanning the gap between the infeed and outfeed conveyors and in driving contact with one outer layer of said articles; and g. said gas impinging on the other outer layer of said articles forcing the layers toward said conveying means so that the layers are conveyed past said casing in spaced relation to the surface thereof by means solely of said belt conveying means.
Claim 3
Dependent Claim
40 words
A device according to claim 1, said casing further comprising, in the upstream edge thereof, a slit disposed for discharging of said gas therethrough, said discharging blowing in a direction opposite to the direction of said transport of said articles.
Claim 4
Dependent Claim

Apparatus as defined in claim 1, wherein said infeed and outfeed conveyors are in the same plane.
Claim 5
Dependent Claim
29 words
Apparatus as defined in claim 1, wherein said casing is of concave shape and said belt conveying means has a complimentary curved path and passes over an idler roller.
