Abstract: An annular container mounted at the base of a passage between a layering tube and a central mandrel is charged with a layered tube of flexible tubing delivered over a floating mandrel when coaxially in contact with mandrel by driving rollers coacting with pinch rollers on the floating mandrel. The tubing passes over the mandrel and gathers in the layering tube while being compacted by two sets of shoes reciprocated 180.degree. out of phase by rotating discs and connecting rods. When sufficient tubing has been delivered the floating mandrel is raised to enable a hot wire to pass between the mandrels to sever the tubing. The layering tube and central mandrel with the container can then be carried by a turntable through further stationary positions where the layered tubing is further compressed by reciprocable rings, a lid is put on the container to form a cassette and the cassette is discharged.

Abstract: In a cassette for dispensing flexible tubing, the tubing is packed in a tightly layered mass between a tubular core and the vertical wall of a casing. Subsequently a cap is mounted in an expanded portion of the casing. The cap has a vertical part fitting the portion and a flange partially overlapping the pack. The cap is secured against rising by punching tongues out of the portion that engage in a groove in the part. The inner surface of part aligns with surface of casing. The junction beneath expanded portion prevents cap from descending as the tubing is dispensed from the top of the pack, over the core edge and through core.

Abstract: A pack comprising a core and pleated tubing is used to provide a series of packages each containing a disposable object such as a baby's nappy along the tubing as it passes over the top edges of the core and then down through the core. The core is turned by means of a lid about a cylinder to twist the flexible material at locations between the adjacent packs to seal the packs at their ends thereby providing hygienic disposal of the waste. A safely located rotatable cutter in the lid is provided for severing the flexible tubing above the top twist.
