Abstract
A cigarette rod making machine wherein the trimming device is movable toward or away from the suction conveyor on which the tobacco stream is formed so as to remove larger or smaller quantities of excess tobacco and to thereby influence the density of the resulting filler. The sidewalls of the tobacco channel which confines the tobacco stream on the suction conveyor have portions which are immediately adjacent to the trimming device and are movable therewith relative to the suction conveyor so that the positions of such portions of the sidewalls relative to the trimming device remain unchanged in all positions of the trimming device. The disc-shaped members establish a boundary between the excess of tobacco and the tobacco which is to form the filler, and the excess is removed by a rotary brush.
Claims10
Apparatus for converting a stream of tobacco particles into a filler, comprising an elongated tobacco channel arranged to receive particles of tobacco which form therein a continuous stream containing particles in excess of the quantity required in the filler and including a foraminous first wall arranged to move lengthwise of the channel and having a first side and a second side, said channel further including spaced-apart first and second sidewalls extending from the first side of said first wall;
- a suction chamber adjacent to the second side of said first wall to attract the particles of the stream to said first side;
- a trimming device spaced apart from the first side of said first wall and arranged to remove the excess from the tobacco stream in said channel, said sidewalls having portions adjacent to said trimming device;
- and means for jointly moving said trimming device and said portions of said sidewalls toward and away from said first wall.
In a cigarette maker, the combination of a conveyor having an elongated portion arranged to transport a continuous stream of tobacco particles so that an exposed side of the stream faces away from said portion;
- a trimming device adjacent to such side of the tobacco stream and movable toward and away from said portion to thereby respectively remove larger and smaller quantities of tobacco particles at the exposed side of the stream;
- spaced apart first and second wall portions flanking the stream in the region of said trimming device;
- and means for moving said trimming device and said wall portions relative to said conveyor so that the positions of said wall portions with reference to said trimming device remain unchanged.
