Abstract
A method and an apparatus for reclaiming tobacco from cigarettes is disclosed. The apparatus and method include a cigarette pack opener and a method of opening cigarette packs wherein the packs are conveyed by an endless conveyor along a path of travel having an arcuate portion and a linear portion. The packs are inputted to the conveyor at the arcuate portion where a pair of circular cutting knives are arranged to cut off the end panels of the pack. The packs are then conveyed to the linear portion of the path where pusher/squeeze bars are urged against the side panels of the pack to deform the pack and cause the cigarettes to fall from the pack by gravity into a collector. The empty pack is conveyed to another arcuate portion of the path where it is discarded.
