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.

A labeling unit for applying labels to containers includes a label removing device, a vacuum drum, and a gluing device. The vacuum drum receives labels at a first transfer position and delivers them to a second transfer position. The gluing device is arranged within an angular region of rotary motion of the vacuum drum between the first and second transfer positions. The vacuum drum moves labels past the gluing device. The label removal device removes either labels or label residues that remain on the vacuum drum in the angular region.

The disclosure relates to a labelling machine for applying labels onto containers using cold glue, comprising a glue supply device. The glue supply device is configured to produce the cold glue from several components, in particular at least one liquid and one solid component, so that the cold glue required for applying the labels can be produced by processing the components, in particular mixing them together.

An adhesive label application system is disclosed. The adhesive label application system may detect that a label has been received within an adhesive application zone of a robotic device. The adhesive label application system may remove, via a first mechanism, a portion of the label from the adhesive application zone. The adhesive label application system may convey, via a second mechanism, an adhesive, of an adhesive-carrying tape, to the adhesive application zone. The adhesive label application system may position, via the first mechanism, the portion of the label within the adhesive application zone after the adhesive is positioned within the adhesive application zone. The adhesive label application system may press, via a third mechanism, the portion of the label to the adhesive to apply the adhesive to the label. The adhesive label application system may configure the label to be adhered to a receiving surface via the adhesive.

A machine for labeling containers conveys, along an advancement direction, the labels to be applied, which have a transfer drum which is adapted to bring individual labels into contact with corresponding containers which are supported by a conveyor. A spraying assembly faces the transfer drum and is adapted to apply glue on the labels; the spraying assembly includes at least one spray gun which has a plate-like glue dispensing body which faces the lateral surface of the transfer drum and is passed through by a plurality of dispensing ports, which are arranged mutually spaced apart along at least one row which extends substantially parallel to the axis of the transfer drum; a controller is configured to actuate a slowing of the advancement speed of the labels with respect to the spray gun before actuating the activation of the spray gun for the application of the glue on the labels.

The present invention provides an apparatus and a method for applying labels to containers or packs, comprising the following steps: taking over a label from a label providing unit by means of a pallet such that a glue application surface of the label faces away from the pallet; conveying the label by means of the pallet past a glue application unit, where the glue application surface of the label has cold glue applied thereto, at least over part of its area; and, subsequently, directly transferring the glue-coated label to a container conveyed by a conveyer or to a pack conveyed by the conveyor.

The present disclosure relates to a labeling apparatus for labeling articles. In one implementation, the apparatus may include a transfer drum having at least one label retaining segment adapted to receive and to retain at least one label, a glue application unit adapted to apply glue onto the label, a cleaning unit adapted to clean the transfer drum and a control unit adapted to selectively activate the cleaning unit into at least any one of: a partial cleaning configuration in which the cleaning unit is configured to partially clean the at least one label retaining segment or a full cleaning configuration in which the cleaning unit is configured to fully clean the at least one label retaining segment.

An apparatus for producing reels of adhesive label laminate, the apparatus comprising a transfer device, the transfer device comprising: a transfer unit, which comprises a perforating blade, and a transfer surface, an adhesive applicator unit for providing an adhesive layer on the transfer surface, a motor to rotate the transfer unit about a first rotation axis, an actuator unit to move the first rotation axis from a standby position to a cutting position,
wherein the transfer device is arranged to form a perforation in the label laminate by cutting with the blade of the rotating transfer unit when the first rotation axis is in the cutting position,
wherein the transfer device is arranged to form an adhesive region on the label laminate by pressing the transfer surface of the rotating transfer unit onto the label laminate such that the adhesive layer is transferred to the label laminate, wherein the transfer device is arranged to move the first rotation axis back to the standby position.

The present disclosure provides a glue supply device for a labeling unit with a glue printer, comprising: a storage tank for glue, a supply line for supplying glue from the storage tank to the glue printer, a continuously delivering glue pump which is embodied to deliver glue from the storage tank into the supply line, and a hydropneumatic reservoir for the glue, wherein the hydro-pneumatic reservoir is arranged at the supply line upstream of the glue printer.

A machine and a method for labeling containers, the machine including a transfer drum, fed by an assembly for unwinding a labeling ribbon and provided with cutting elements, which is adapted to bring the individual labels, separated after cutting, into contact with corresponding containers which are supported by a conveyor; a roller for spreading adhesive faces the transfer drum and is designed to apply, to the labels that are present on the ribbon, at least one line of adhesive prior to their separation from the ribbon.
