Method and apparatus for producing pouched tobacco product
In a method and apparatus for producing a small pouch with a predetermined amount of particulate material therein, a predetermined amount of the particulate material is portioned from a bulk supply and compacted into a single discrete caplet. The caplet is then deposited into an open hollow pouch closed at one end thereof, and the open end is then closed with the caplet between the closed ends of the pouch. The caplet in the pouch is then compressed to return it to its particulate form. The particulate material may be granular or shredded tobacco.
