A vacuum drum for a labelling unit of a labelling machine has the segments arranged next to each other to collectively form a circumferential surface of the vacuum drum. A typical segment has vacuum-holders that holds ends of the label. The holders are offset along the drum's circumferential surface. The segment also has a carrier plate and a label arc between the first and second vacuum holders. The first vacuum-holder comprises a first housing and the second vacuum holder comprises a second housing. At least one of the carrier plate, the housings, and the label arc is formed by additive manufacturing.

An apparatus for feeding a strip (1) of linerless labels (2) to a drum (60) for applying the labels onto containers comprises a strip support (10) for supporting a reel of a strip of linerless labels (2) and allowing unwinding of the strip (1) from the reel; a first motorized drive roller (20), designed to rotate in a direction of rotation to cause unwinding of the strip (1) arranged on the support (10) and continuous feeding thereof downstream in an advancement direction (X-X) of the strip; a second motorized drive roller (50), designed to rotate such as to cause advancing of the strip (1) towards the drum (60); a chamber (100) which is arranged between the first drive roller (20) and the second drive roller (5) in the direction (X-X) of advancement of the strip; a first upstream roller (11) of the chamber, motorized and rotating in the direction of rotation for advancing the strip, and a second downstream roller (120a) of the chamber, motorized to rotate in a direction opposite to that of the first upstream roller, said rollers being arranged at a respective upstream or downstream edge of the opening (101) of the chamber (100). Pressurized air is fed to a dispensing nozzle (202) arranged to dispense the pressurized air towards the inside of the chamber (100) and a control unit (500) is configured and arranged to cause the unwinding and continuous advancing movement of the strip (1) from the support (10) to the upstream roller (11) of the chamber (100) and an advancing movement of the strip with a predefined speed and tension between said downstream roller (120a,120) of the chamber (100) and the second motorized drive roller (50).

A device for removing labels from a label applicator in a produce labeling system is provided. The device includes a label pickup roller positioned in the downstream path of the label applicator. A spindle is positioned on the machine such that the label pickup roller can be positioned as described. When a label attempted to be applied to produce from the label applicator does not get applied for any reason, the pickup roller removes this unapplied label from the label applicator before the label applicator travels back to the label dispenser to receive another label for the next labeling cycle.

The invention relates to a wrapping device (300) for wrapping a band around a wound up roll (5), characterised in:a storage (301) for said band (303) to be wrapped around said wound up roll (5),a first conveyor (330) positionable adjacent said wound roll (5), for conveying said band (303) to said roll (5),said first conveyor (330) comprising a cylindrical drum configured for rotation about an axis (W),said drum (330) having a surface configured for receiving and transferring said band (303) to said wound up roll (5) by a vacuum applied to said band (303) via apertures (331) formed in said surface.

A labeling machine including a conveyor of containers to be labeled along an advancement path and at least one labeling station arranged along the advancement path. The labeling station includes an assembly for unwinding a label ribbon, on which multiple labels are printed in succession, and at least one drum designed to receive on a lateral surface thereof the label ribbon and/or the labels obtained by cutting the label ribbon. Multiple sliders are arranged at the peripheral region of the drum; at least one of the sliders has contact regions designed to engage by contact the label ribbon and/or the labels, provided with a different degree of mutual adherence with respect to the material of which the label ribbon is made.

A label application system for applying paper non-pressure adhesive labels to relatively short, round, straight-walled articles is constructed and designed so that labels to be applied to passing articles are delivered to the label application zone on a vacuum conveyor in a short feed orientation, with each label being oriented lengthwise across a width of the vacuum conveyor. At the time of labeling, the label is held stationary on a flat vacuum surface, and the label is applied by spinning the articles past the vacuum surface. As a result, the system is capable of labeling articles at processing speeds of up to or exceeding 800 articles per minute.

A container-labeling apparatus includes a label-strip feeder having a vacuum drum and a vacuum cylinder that has vacuum regions extending between different angular ranges. A first vacuum source provides the vacuum at the vacuum drum and a second vacuum source provides the vacuum at the vacuum cylinder. During operation, the vacuum regions provide different under-pressures.

There is disclosed a labelling group for advancing a series of labels to be applied onto relative articles. In one implementation, the labelling group may include a first drum adapted to convey a strip of labels along a first path and towards a transfer station; a cutting mechanism adapted to cut a sequence of single labels from the strip; a second drum fed by first drum with cut single labels at the transfer station and adapted to convey simultaneously a required number of cut single labels along a second path. The first drum may move at a first tangential speed at the transfer station, and the second drum may move at a second tangential speed at the transfer station, where the first tangential speed is different from the second tangential speed and is adjusted on the basis of required number of cut labels to be simultaneously conveyed on second drum.

A labeling machine includes a conveyor of containers to be labeled along an advancement path and at least one labeling assembly arranged along the advancement path of the containers; the labeling assembly includes an unwinding assembly for a label ribbon, on which multiple labels are printed in succession, and at least one conveyance drum designed to receive the label ribbon and/or the labels obtained by cutting the label ribbon. At the peripheral region of the conveyance drum there is a plurality of sliders, which are mutually angularly spaced around the axis of the conveyance drum. At least one of the sliders has resting regions designed to engage by contact the label ribbon and/or the labels, which are adapted to apply, with respect to the label ribbon and/or the labels, mutually different attraction forces toward the corresponding slider.

A labelling unit and a method for labelling containers is provided. Said method provides rapid and reliable switching movements with low noise development and low wear of the mechanical components in that suction bars for suctioning label areas at places where container gaps occur can be actively switched back to an inner position, in which they do not come into contact with a gluing unit, and in that the switching process is triggered with the aid of a stationary toggle lever.
