A machine for labeling containers, which includes a transfer drum, fed by an unwinding assembly for unwinding a labeling ribbon, which is provided with cutting elements which are mutually angularly spaced apart around an axis thereof; the unwinding assembly is drivable by control elements which are adapted to command, during the rotation of the transfer drum about its own axis, at least one variation of the feeding speed of the labeling ribbon, with respect to the peripheral speed of the transfer drum; the control elements are adapted to command at least one first slowing of the feeding speed of the labeling ribbon during the activation of the cutting device.

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.

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, which includes a conveyor for conveying containers to be labeled and at least one labeling station provided with an unwinding assembly for a label ribbon on which a plurality of labels are printed in succession, and at least one drum which is provided, peripherally, with runners which have at least one relief portion, in relief with respect to the lateral surface of the drum; a spreading roller for spreading adhesive on the label ribbon; at least one of the runners has at least one contoured part in order to allow the application, by the spreading roller, on the portion of the label ribbon and/or of the labels that is on the contoured part, of at least one adhesive imprint which has at least one region without adhesive.

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.
