ABSTRACT:
An apparatus for closing and transporting tobacco pouches includes a turret type feed conveyor, a reciprocating preconveyor and a pocket-chain type discharge conveyor. Closing apparatus are associated with the pre-conveyor. A tobacco pouch is transported from the feed conveyor to one of a plurality of movable pack receptacle regions at a feed station, and then transported, by reciprocating fingers, to a discharge station where closing apparatus seals the pouch. The sealed pouch is thereafter discharged to a pocket of the discharge conveyor. Each discharge station is provided with a pair of spaced, movable walls which receive a pouch therebetween, retain the pouch during sealing and are thereafter moved to carry the sealed pouch to the discharge conveyor. Finger retraction and extension apparatus are provided to move the fingers into engagement with a pouch at the feed station and to disengage the fingers from a pouch at the discharge station.
