Abstract
Circumferentially extending recesses in the peripheral surface of a rotating suction wheel are filled with tobacco shreds which are delivered in the form of a narrow stream by a pneumatic conveyor having a narrow tobacco propelling channel extending radially of the suction wheel and receiving the shreds of the stream in a current of compressed air. The surplus of shreds is removed by the current and/or by a trimming device which is installed in the interior of the pneumatic conveyor, and such surplus is recirculated through the distributor of a cigarette rod making machine and back into the pneumatic conveyor. The batches are used to form the interrupted core of a composite tobacco filler wherein the core is surrounded by a tubular envelope containing a different blend of tobacco.
Claims20
A method of forming discrete batches of tobacco particles at the periphery of a rotating conveyor, comprising the steps of converting the particles into a first stream and forcibly advancing the stream along a first portion of a predetermined path;
- converting the first stream into a narrower second stream and forcibly advancing the second stream along a second portion of said path;
- and conveying successive increments of the second stream toward the periphery and substantially radially of the conveyor.
Apparatus for forming discrete batches of tobacco particles, comprising a rotary conveyor having a peripheral surface provided with distinct recesses for tobacco particles, said recesses being separate from each other;
- and means for delivering tobacco particles to said conveyor, including a tubular second conveyor having a particle-guiding wall extending substantially radially and toward the peripheral surface of said rotary conveyor.
