Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.

A gluing arrangement for applying glue to labels in a labeling machine, which gluing arrangement has a heated roller element and one or more temperature sensors which sense the temperature of a portion of the roller element. The temperature sensors are protectively sealed against contamination and mechanical damage, such as by being sealed inside the body of the roller element. The gluing arrangement also has a heating arrangement which includes one or more induction coils for heating the roller element. The heating arrangement and/or induction coils are positioned within the roller element such that they are surrounded by either an inner or outer surface of the roller element.

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.

The present invention provides a labelling apparatus for applying labels to containers, comprising a gluing device having a glue roller and a glue-application unit, 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 extentas seen in the axial direction of the glue rollerof the surface of the glue roller.

A labeling machine includes a conveyor to move containers to be labeled along an advancement path and at least one labeling station arranged along the advancement path. The labeling station includes an unreeling assembly for a label ribbon, on which multiple labels are printed in succession, and at least one drum designed to receive on its lateral surface the label ribbon or the labels obtained by cutting the label ribbon. At least one skid is arranged at the peripheral region of the drum and has at least one relief portion with the relief directed outward with respect to the remaining part of the lateral surface of the drum. At least one glue roller is arranged laterally to the drum. At least the relief portion of the skid is made of an elastically yielding material.

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.

The present invention provides a labelling apparatus for applying labels to containers, comprising a gluing device having a glue roller and a glue-application unit, 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 extentas seen in the axial direction of the glue rollerof the surface of the glue roller.

A device for removing hot-melt adhesive from a rotating, vertically-arranged roller (1), comprising: a hollow, preferably hollow cylindrical, scraper (2), characterized in that the scraper (2) comprises an opening (6) on the circumferential surface thereof along the longitudinal axis, at which opening a strike plate (3) that protrudes radially outward is arranged, and wherein the strike plate (3) is arranged such that it can be brought into a position for removing adhesive from the roller (1) and can convey the removed adhesive towards the circumferential inner side of the scraper (2).
