Abstract
Unsealed packets of cigarettes emerging from a packaging machine present an outer surface that consists of an opaque wrapping material, to which a revenue stamp and a coupon are affixed as the packets are transferred directly and in an ordered succession from the packaging machine to a cellophaner; on reaching the cellophaner, each packet in turn is enveloped in a sheet of transparent overwrapping material covering the opaque wrapping material, the revenue stamp and the coupon, and the overwrapping sealed in such a way that the finished packet will remain substantially airtight
