Abstract

A distributor or hopper is part of a cigarette production machine and serves for dressing the tobacco in the provision of a continuous tobacco strand. An integral part of a distributor is a metering system which prepares the tobacco for the production of the tobacco strand. To separate out undesirable constituents, such as foreign bodies, stalks or ribs, from the tobacco, at least one sifter (15) is provided. The latter precedes the metering system of the distributor in the working direction, in particular is arranged outside the distributor, so that sifted tobacco is introduced into the distributor.
