ABSTRACT:
The distributor of a cigarette rod making machine delivers particles of tobacco into a stream building zone wherein the particles are accumulated into a continuous stream. The surplus of tobacco is removed by an adjustable trimming device and the removed surplus is transported back to the distributor for reuse. The quantity of removed surplus is measured by a weighing device whose transducer transmits signals which are compared with signals denoting the position of the trimming device, and the resulting signals are used to adjust the rate of delivery of tobacco particles to the stream building zone. The weighing device has a frame which carries two pulleys for an endless belt. The frame can pivot about the axis of one of the pulleys or it can be tiltably mounted on a fulcrum between the two pulleys.
