Abstract
An apparatus for manipulating a multilayer stream of tobacco particles with randomly intermixed foreign particles has a vibratory conveyor which advances the stream toward and discharges successive increments of the stream onto the upper reach of an endless belt or chain serving to advance the increments at a speed exceeding the speed of advancement of the stream by the vibratory conveyor. The endless belt or chain discharges a single layer of tobaco particles and foreign particles, and such single layer is caused to move past a segregating unit which detects and expels foreign particles therefrom.
Claims23
Apparatus for transforming a multilayer stream of tobacco particles into a single layer during advancement of the particles in a predetermined direction along an elongated path, comprising a first transporting unit including at least one vibratory first conveyor having means for advancing the particles at a first speed along a first portion of said path;
- and a second transporting unit located downstream of said at least one first conveyor and included two second conveyors having means for advancing the particles at a second speed higher than said first speed along a second portion of said path, said second conveyors being disposed one above the other and defining an air-confining channel for the advancement of particles along said second portion of said path, said second conveyors including endless flexible elements one of which includes an upper reach below and the other of which includes a lower reach above said channel.
