A method and a device for the ultrasonic welding of a first component to a second component of an electronic cigarette cartridge, wherein both components are made of a plastic material; the device includes an ultrasound generator, which delivers an electric pulse to a vibrating assembly, which, in turn, includes a converter designed to turn the electric pulse into a mechanical vibration movement and transfers it to a sonotrode, which directly transmits the energy in the form of vibrations to the two components to be welded; the sonotrode is designed so as to simultaneously weld a plurality of first components to the respective second components and cooperates with a plurality of striker elements, each associated to a respective first component and to a respective second component to be welded; and wherein each striker element is connected to a sensor, which is designed to detect a parameter of the welding process carried out to weld the first component to the second component and to control the welding process carried out to weld the first component to the second component based on the parameter.

The invention relates to a sonotrode for the ultrasonic welding of plastic components of an electronic cigarette.

The sonotrode comprises: a body comprising a first end which can be connected to an ultrasound generator, and a second end; a cavity that develops from the second end towards the first end, for receiving at least partially a plastic component of an electronic cigarette to be welded. The cavity defines an opening at the second end of the body, communicating with the outside of the sonotrode.

In particular, at the opening, the cross section of the cavity has an outline comprising: a first portion that has the shape of a first arc of a reference circumference, which comprises a first end and a second end, opposite each other; and a second portion, that has the shape of a second arc of said reference circumference, which comprises a first end and a second end, opposite each other.

The aforementioned outline further comprises: a third portion, connected to the first end of the first portion and to the first end of the second portion, which develops externally with respect to the reference circumference; and a fourth portion, connected to the second end of the first portion and to the second end of the second portion, which develops externally with respect to said reference circumference.

A packaging machine to make an airtight wrapper includes a wrapping sheet wrapped airtight around a structured assembly consisting of an organized group of smoking articles associated with a reinforcement insert. The reinforcement insert includes, in working sequence on one or more cyclical conveyor devices of the wheel or carousel type, a structured assembly formation unit, a combination unit suitable to combine the structured assembly with said wrapping sheet, a wrapping sheet work unit and a welding unit.

Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The first component includes a first facing surface that faces the second component, and a first outermost edge of the first facing surface. The second component includes a second facing surface that faces the first component, and a second outermost edge of the second facing surface. The first outermost edge and the second component are not joined or welded to each other, and the second outermost edge and the first component are not joined or welded to each other.

An aerosol-cooling element (100) for an aerosol-generating article. The aerosol-cooling element (100) comprises an interior structure (102) and a wrapper material (104) secured around the interior structure (102). The wrapper material (104) comprises a first portion (106) welded to a second portion (108) of the wrapper material (104).

A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

A molding apparatus, a cigarette filter rod and a preparation method thereof are disclosed. The molding apparatus comprises a single-screw extrusion system and a cooling setting system. The single-screw extrusion system comprises a feeder and an extruder. The feeder is arranged on the extruder. The extruder comprises a cylinder. A heater is arranged outside the cylinder. A screw is arranged inside the cylinder, and a mouth mold is arranged at one end of the cylinder. The cooling setting system comprises a round tube and a cooler. The cooler (6) is arranged outside the round tube. One end of the round tube is butted with the mouth mold of the extruder; and multiple groups of grooves are formed on threads of the head of the screw.

An aerosol-cooling element for an aerosol-generating article. The aerosol-cooling element comprises an interior structure and a wrapper material secured around the interior structure. The wrapper material comprises a first portion welded to a second portion of the wrapper material.

Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The second component includes a facing surface that faces the first component, and an outermost edge of the facing surface. The other end of the connection section is joined or welded to the facing surface of the second component, at a position away from the outermost edge.

A leftover material is prevented from being generated from a part, of a cartridge that forms a vapor product, where positioning is performed. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, a connection section that extends between the first component and the second component, with one end connected to the first component and another end connected to the second component, and a guide section that extends from the first component, and that is not joined or welded to the second component. The second component includes a receiving section where the guide section fits.
