ABSTRACT A turret, comprising a carrier disc and a set of parallel hollow mandrels carried thereby, is rotatable to carry a mandrel from (a) a tubular wrapper stock-receiving station where tubular wrapper stock from a supply roll of flat-folded tubular film wrapper stock is advanced by rollers to form a build-up of shirred film stock on the mandrel, to (b) a wrapper stock-dispensing station where the leading end of the shirred build-up is sealed and the emergence of an elongate product article driven by a loading ram withdraws the required length of tubular wrapper stock material from the build up to dispense a wrapper of the required length which is then severed by severing means while the leading end of the next successive wrapper is sealed by hot welding bars. This apparatus enables wrappers of varying lengths to be manufactured from a given supply roll of flat-folded tubular film wrapper stock in a continuous and automatic manner.
