A PROCESS OF FEEDING A TOBACCO STREAM, A HOPPER AND A MACHINE EQUIPPED WITH A HOPPER

摘要

A hopper is connected with a machine for manufacture of tobacco industry products including a tangential separator sequentially feeding an entry stock of the hopper. The distribution between portions of tobacco streams including a large proportion of short tobacco fibers and portions including a large proportion of long tobacco fibers of the tobacco stream set apart in advance in the entry stock is essentially longitudinal when the stream arrives on a transfer belt of the hopper. By imposing a change of direction on the tobacco stream as well as a reduction of speed of displacement of this stream, this longitudinal distribution is transformed into a transverse distribution. A spiked or barbed roller, placed at a right angle to this latter stream, homogenizes the distribution, making it possible for the distribution to be regular between short fibers and long fibers in the tobacco stream arriving through the chimney for the manufacture of the tobacco rod.
