Abstract: A device for automatically orienting containers to be labeled entering a labeling machine, which includes at least one emitter device, which is adapted to emit electromagnetic radiation toward the containers, elements of detecting the electromagnetic radiation reflected by the containers, and processing and control elements adapted to identify the position of the optically detectable defects on each one of the containers; the emitter device including a lighting module with an emitting face which has at least one first emitting portion and is associated with a plurality of first sources of electromagnetic radiation of a first type which are designed to activate/deactivate the first emitting portion; the emitting face of the lighting module further including a second emitting portion, and an associated plurality of second sources of electromagnetic radiation of a second type, different from the first type, which are designed to activate/deactivate the second emitting portion.

Abstract: A device for applying, around groups of two or more containers, a tape provided on one surface with adhesive without discontinuities, which comprises a carousel provided with plates shaped so that each one accommodates a group of containers to be wrapped together with the tape, a drum for cutting and transferring portions of tape of a length necessary to wrap each group, a roller for unwinding the tape for feeding the drum, a roller for preliminary unwinding of the tape from a reel, adapted to feed the unwinding roller with the interposition of a compensation buffer and a device for compensating the tension of the tape between the reel and the preliminary unwinding roller.

Abstract: An apparatus for applying leaflets to containers, which comprises a fixed framework that supports at least one magazine for containing leaflets which faces, with its outlet, the peripheral region of an application drum, which can rotate about its own axis, with respect to the fixed framework, and is provided with at least one accommodation seat for at least one respective leaflet picked up from the outlet of the magazine and intended to be transferred onto at least one respective container moved by a conveyor; the application drum can be actuated with a continuous rotary motion about its own axis and is provided, at the accommodation seat, with elements for retaining the leaflet that can be moved on command between a condition that lies close to the axis of the application drum and a condition that is spaced from the axis of the application drum.

Abstract: A carousel labeling machine for pre-glued labels on a ribbon is provided. The machine includes a label cutting and transfer drum fed by a roller for unwinding the label ribbon from a reel, and rotating in step with the carousel, in the sense that the unwinding roller provides the drum with the label intended for the container that rests on a specific receptacle of the carousel. A cutter of the drum is actuated so as to cut the label when a photocell sends a clearance signal as a consequence of the presence of the container. If at least one container is missing on the corresponding receptacle, the photocell sends a command to the unwinding roller to feed the label ribbon to the cutting and transfer drum at a speed reduced with respect to the normal speed.
