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.
