ABSTRACT:
The invention relates to an apparatus for applying a heat-shrinkable band to the neck or to the body of a container. The apparatus comprises a feeding assembly for advancing a continuous sleeve of heat-shrinkable polymeric material along a predetermined path to slip the sleeve over the cap of the container. A cutting assembly then severs the sleeve to leave on the container cap a short band which can be heat-shrunk to form the tamper-proof seal. The cutting arrangement includes a blade carrier rotatable about the feed axis of the sleeve. An extendable cutting blade is mounted to the blade carrier. When the blade is extended to the cutting position, it pierces the sleeve. By rotating the blade carrier, the cutting blade is caused to slit the sleeve circumferentially until a complete cut is effected. The advantage of this arrangement is reduced blade wear, higher speed and possibility to apply the sleeve without any gating or timing of the containers.
