Problems solved by technology

[0004] The problem with this embodiment is that when the labeling machine is stopped, the glue line left on the glue roller dries up and is sometimes difficult to remove
Furthermore, in such systems there is the risk that the glue changes its chemical structure and / or composition through contact with ambient air, in particular with atmospheric oxygen
Furthermore, the glue line in known systems extends over the entire height of the glue roller, ie over the extent of the glue roller in its axial direction, so that the applied glue is not completely taken up by the generally smaller labels or trays

Abstract

The present invention provides a labelling apparatus for applying labels to containers, comprising a gluing device having a glue roller (301) and a glue-application unit (372), which is assigned to the glue roller and is intended for applying glue to the glue roller, wherein the glue-application unit has at least one accommodating space for accommodating the glue, and wherein the glue roller and / or the glue-application unit are designed, and arranged in relation to one another, such that glue which is located in the accommodating space is applied to the surface of the glue roller only in one or more sub-regions of the overall extent - as seen in the axial direction of the glue roller - of the surface of the glue roller.

Description

technical field [0001] The invention relates to a device and a method for the targeted application of glue to labels of containers, in particular of jars, glass bottles, PET bottles, etc., in a labeling device. Background technique [0002] Labeling machines are used in the beverage processing industry to continuously and efficiently apply labels to continuously conveyed goods or containers. In this regard, the container may be a jar, a glass bottle, a plastic bottle or the like. In addition to self-adhesive labels, labels are also known to which glue is first applied in order to subsequently attach the glued label to the container. A suitable glue is applied to the back of the label, for example via a gluing device with a glue roller. This can be done directly, ie glue is applied by means of a glue roller to the label which is passed by the glue roller by means of a vacuum cylinder. However, it can also be done indirectly, that is, the glue is first transferred by means ...
