A vacuum drum for container labeling includes vacuum holders for holding a label. Each holder has a bistable rotational switch that switches between operating positions as a result of its switch actuator interacting with stationary switches during the drum's rotation. In one operating position, a label receives glue from a glue station. In the other, the holders avoid engagement with the glue station.

A gluing system for applying glue on products is disclosed. The gluing system includes a glue applicator configured to deposit melted glue on products, a glue container configured to contain excess melted glue discharged from the applicator and fresh melted glue, a glue delivering unit configured to deliver glue from the container to the applicator and a glue discharging unit configured to convey excess glue not used by the applicator to the container. The container is divided by a partition into a first chamber, containing the fresh melted glue, and into a second chamber containing the excess melted glue and separated from the first chamber. The partition includes a filter allowing flow of the fresh melted glue and the excess melted glue from both the first and second chambers to the delivering unit.

The present disclosure relates to a hot glue unit for a labeling machine in the beverage processing industry. The hot glue unit includes a housing, a glue roller disposed in an interior of the housing, a glue container, and a filter unit including an extractor connected to the housing. The extractor is to extract gases from the interior of the housing and supply the gases to the filter unit before the gases are to exit the hot glue unit.

Provided herein is a water-activated adhesive comprising an aqueous emulsion of vinyl acetate, polyvinyl alcohol, and glycerin. The adhesive has no significant tack prior to being activated, can be repositionable for at least 1 minute after activation, and can form a strong bond less than two hours after activation. Also provided are labels comprising the water-activated adhesive, methods for producing and using the water-activated adhesive, and systems for labeling articles with the water-activated adhesive.

An apparatus for applying a respective label, on a corresponding container, in particular in the form of a bottle, especially in the form of a container, or bottle, made of plastic material; in particular said label being adapted to circumferentially wrap the body of said container, or bottle, includes means for applying a corresponding adhesive or glue on one or more corresponding parts, in particular on the outermost parts, of the respective label; said means for applying a corresponding adhesive or glue being movable into a close position for engaging said one or more corresponding parts of said label and for applying thereon said adhesive or glue and a position disengaged from said label, and in particular which lets the label freely pass without said adhesive or glue being applied, which position disengaged from said label, and in particular which lets the label freely pass without said adhesive or glue being applied, is close to the label itself.

An apparatus for the application of hotmelt onto labels, includes a vacuum cylinder, a gluing unit with a glue roller unit, and a glue reservoir. The gluing unit is pivotally mounted such that it can be slewed away from the vacuum cylinder and the glue reservoir is designed as a self-contained unit that is structurally separate from the pivotable gluing unit. A glue reservoir for hotmelt includes an inner body with heating fins, a thermally insulating jacket enclosing the inner body, and an outer casing made of plastic.
