Abstract: A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

Abstract: A packaging unit of articles in boxes includes a mandrel, a movement device, a feeding device, a folding device, and a first retaining device. The mandrel is configured to accommodate at least one of the articles therein. The movement device is configured to move the mandrel along a movement trajectory. The feeding device is configured to feed at least one blank towards the mandrel. The folding device is configured to cooperate with the mandrel to fold at least one panel of the blank being wound around the mandrel, and to form one of the boxes. The first retaining device is movably guided parallel to the movement trajectory and is configured to cooperate with the mandrel, along a section of the movement trajectory, retaining the at least one panel of the blank, wound on the mandrel, against an abutment surface of the mandrel extended parallel to the movement trajectory. A packaging method of articles into boxes by means of such a unit is also described.

Abstract: A packaging unit for packaging articles in boxes includes a mandrel, a movement device, a feeding device, a first abutment surface, and a retaining device. The mandrel is configured to accommodate at least one of said articles inside it. The movement device is configured to move said mandrel along a movement trajectory.

The machine base affords a plurality of mounting points arranged symmetrically on either side of a vertical median plane, passing longitudinally through the base, so that the position of the feed unit can be reversed in mirror image relative to the median plane, as also can the positions of the first folding and closing assembly and the second folding and closing assembly.

Abstract: In a manufacturing system utilizing a cigarette maker linked to a packer, cigarettes temporarily surplus to requirements are stored in containers, each provided with an opening by way of which it can be filled and emptied. A full container is picked up by a first pivoting arm from a magazine and overturned above a bearing surface advancing along a feed direction parallel to this same surface, so as to direct the opening downwards and allow the cigarettes to drop onto the surface. During the step of unloading the cigarettes, the container rests on a hopper and is traversed from a first station toward a second station along a direction parallel and opposite to the feed direction of the bearing surface, so that the cigarettes can be released more quickly from the container. After being emptied, the container is picked up from the second station by a second pivoting arm and put into a magazine with other empty containers.

Abstract: Cigarettes are transferred in batches adopting a procedure that includes the steps of feeding loose cigarettes en masse into a hopper with a back wall and two side walls delimiting a top inlet and a bottom outlet, also a shutter by which the bottom outlet is opened or closed, and actively varying the geometry of the side walls so that the internal volume of the hopper is adapted to accommodate the quantity of cigarettes admitted through the inlet, by means of an actuator mechanism connected to the side walls. Thus, it becomes possible to monitor and control both the rate at which the cigarettes flow into the hopper, and the pressure to which the single cigarettes are subjected while occupying the hopper and during the process of filling a tray.
