A cutting drum for a labeling machine, which includes a drum main body designed to receive in adhesion a label ribbon on which multiple labels are printed in succession; along the perimeter of the drum main body there is at least one cutting device which includes a respective suction chamber, which accommodates at least one blade; the suction chamber is connectable to air suction elements, in order to attract the label ribbon toward the inside of the suction chamber and against the blade, in order to produce the cutting of the label ribbon; the cutting device comprises a respective box-like body for supporting the blade which forms internally the suction chamber and is detachably supported by the drum main body; the blade is coupled to the box-like body by virtue of detachable retention elements.

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.

A beverage container handling machine, such as a beverage container filling machine or a beverage container closing machine, is used to handle beverage bottles, cans, and similar containers, which containers are configured to hold or contain a beverage, such as water, soft drinks, beer, wine, and juices, or a similar product for transport and consumption by consumers of beverages and similar products.

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 labeling machine includes a conveyor of containers to be labeled along an advancement path and at least one labeling station. The labeling station includes an unreeling assembly for a label ribbon, and a cutting drum. At least one cutting device is provided and has a respective suction chamber, which accommodates internally a blade. The suction chamber is connectable with an air suction device, in order to attract the label ribbon toward the inside of the suction chamber and against the blade, in order to cut the label ribbon. The cutting device includes a respective blade supporting element which is coupled to the cutting drum and supports the blade. This blade supporting element is elastically deformable in order to allow the coupling/uncoupling of the blade to/from the blade supporting element.

A labeling machine includes a conveyor of containers to be labeled along an advancement path and at least one labeling station which is arranged along the advancement path of the containers. The labeling station supports at least one cutting device for the label ribbon. The cutting device includes a respective suction chamber which accommodates internally at least one blade. The suction chamber is connectable with an air suction device, in order to attract the label ribbon toward the inside of the suction chamber and against the blade and in so doing cutting the label ribbon. The cutting device includes at least one respective blade supporting block which is supported by the cutting drum and supports the blade. At least one portion of the blade supporting block is provided internally with at least one cavity for attenuating noise generated by cutting the label ribbon.

A method is for manufacturing a container (C), such as a PET bottle, with a convex bottom and a self-bearing support, typically a self-bearing label. In particular, the method is for manufacturing a container (C) with a convex bottom and a self-bearing support including providing a plurality of containers (C) having a convex bottom. A machine (100) is provided for applying strips made of flexible material to the containers (C) and a plurality of support elements (1, 101, 201) for the containers (C). The support elements (1, 101, 201) are strips made of a support material. The method further includes feeding the plurality of containers (C) to the machine (100) and applying a support element (1, 101, 201) to each of the containers (C).
