Heat sensitive containers with loosely fitting circumferentially heat shrinkable sleeves are conveyed linearly while rotating, past heating means for impinging hot gas against the sleeve serially from the bottom to the top thereof to heat shrink the sleeves around the bottles; also disclosed is delivering different amounts of heat per unit height to at least two axially adjacent horizontal zones of said sleeve.

Method for applying a heat shrinkable sleeve to a plastic bottle

There is disclosed a device for applying a liquid adhesive onto the surface of bottles moving in upright seriatim fashion on a horizontal moving conveyor at an adhesive applying station. The device includes a container for liquid adhesive and a pivoted frame supported over the container which supports a beveled feed wheel on an inclined shaft driven by its connection to an electric motor. The beveled feed wheel rotates partly submersed in the adhesive and engages a cylindrical applicator roller freely rotatable on a vertical axis at the applying station. The outer periphery of the roller is comprised of a porous, resilient layer, e.g. a spongy urethane layer which receives adhesive from the beveled facing of the feed wheel. The beveled facing of the latter is non-porous and smooth, e.g. a steel facing. The roller is properly loaded with adhesive transferred by the feed wheel and is also driven by the wheel in a direction corresponding with movement of the bottles in the applying station; whereat the roller surface layer engages the bottle surface and applies adhesive thereto.
