Abstract: A manufacturing machine for producing disposable cartridges for electronic cigarettes can have a manufacturing drum supporting at least one group of seats, each adapted to receive a component of the disposable cartridge; and a feeding unit which feeds the components of the disposable cartridges to the seats. Each seat has a housing through channel crossing the manufacturing drum from side-to-side to contain a component and a pair of opposite jaws mounted in the housing channel and movable between a gripping position, in which they engage a component arranged in the housing channel and a transfer position, in which they do not engage the component. Each pair of jaws has two teeth arranged at the top and projecting from the corresponding jaws towards the center of the seat, so that the two teeth hold the component inside the seat at the top when the two jaws are in the gripping position.

Abstract: A label-rejecting station, where labels are carried by a support band along an advancing path. The rejecting station includes a deviator element and a contrast element. The deviator element is arranged along the advancing path and movable between an inactive position and an active position wherein it contacts the support band at a first surface thereof, deviating the advancing path. The contrast element is arranged along the advancing path downstream of the deviator element and includes: an abutting surface provided for receiving partially thereon a second surface of the support band, opposite to the first surface; and a detachment edge provided for detaching a label from the support band when the deviator element moves into its active position.

Abstract: A laser soldering device for laser soldering an electric circuit of a heating portion of an electronic cigarette, the soldering device including a head having an emitting area where a laser beam is emitted and a feeding device to feed a heating portion of an electronic cigarette along a feed path, where the heating portion faces the head at the emitting area. A movement device is operatively connected to the head to move the head between first and second points of the electric circuit such that the laser beam is perpendicular to the respective surface to be soldered at the first and second points to form first and second connections, respectively. The head generates two distinct pulses of the laser beam at the first and second points.

Abstract: A coupling unit and method for inserting a support fitted with a hygroscopic pad in a base during the manufacture of a disposable cartridge for an electronic cigarette; are provided: a first seat that accepts the support fitted with the hygroscopic pad; a second seat that accepts the base and can be axially aligned with the first seat; a transfer device that inserts the support fitted with the hygroscopic pad in the base by applying a relative axial movement between the support fitted with the hygroscopic pad and the base; and a suction device, which is coupled to a first end of the base opposite to a second end of the base through which the support fitted with the hygroscopic pad enters, and causes suction that acts inside the base.
