A roll-fed labelling machine that can be quickly changed to process containers and labels of different sizes does not require changed cutters to match different label sizes by engaging at least 50% of each label on the vacuum drum before it is cut from the web. Infeed guides and roll-on-pad assemblies, specific to individual container sizes can be installed swiftly by means of fixed alignment pins. The starwheel, having a diameter that is only five times the diameter of the mid-size container that the labelling machine is designed to process reduces abrasion and vibration. Starwheels that are aligned and with preset timing adjustment integral with the starwheel members for each container size are changed quickly to synchronize starwheel timing with that of the labelling machine. A glue applicator has a heater cartridge in the glue bar for warming the glue to a suitable range, while the glue roller has a circumference of not more than nine inches to control thermal losses and to reduce glue 'slinging' and glue 'stringing.'

Labelling machine

An apparatus and method for applying a heat shrinkable film to a container having a right-circular, cylindrical sidewall section and at least one inwardly directed end section. A film segment is transported by a rotary vacuum drum past an adhesive station, where adhesive is applied to leading and trailing ends of the film. Then, the film is wrapped completely around the container by the co-operative action of a vacuum drum and an arcuate roll-on pad, leaving a free-standing portion of the label extending past the sidewall section. In the overlapping ends of the film, a first seam is formed by compressive forces between the vacuum drum and the container sidewall. A second seam is simultaneously formed by the compressive force of an active label deflector on the vacuum drum, adapted to press the free-standing portion of the label ends against the end section of the container. Heat is then applied to the label, shrinking the free-standing portion upon the container's end section.
