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.
