Abstract
A tobacco cutting machine wherein two endless chain conveyors define a horizontal channel of diminishing height for conversion of tobacco into a cake whose leader advances into the range of and is shredded by orbiting knives. The lower chain conveyor extends rearwardly beyond the upper chain conveyor and is located below the lower end of a vertical passage which is defined by an upright duct having several mobile walls which flank different portions of the passage and are pivotably mounted in the housing of the cutting machine. One of the mobile walls is located immediately above the rearwardly extending portion of the lower chain conveyor and is oscillated at a high frequency by an eccentric drive. Another mobile wall of the duct is located above the one mobile wall or directly above the rear end of the upper chain conveyor and is oscillated by a second eccentric drive at a lower frequency but through larger angles. This insures that tobacco leaves which are showered into the open upper end of the duct are free to move relative to each other during downward movement in the duct and thereupon advance edgewise into and in the channel to form a laminated cake of predictable density before the leaves reach the path of orbiting knives.
