Abstract: A twisting apparatus has a rotor driven around an axis by an electric motor, a microcontroller; three elastomeric balls at ends of pivot arms mounted to a lower surface of the rotor such that arms may pivot to move the elastomeric balls toward or away from the central axis, a clutch mechanism having a clutch plate with pins interacting with the pivot arms such that rotation of the rotor from a stopped position in one direction closes the elastomeric balls toward the central axis, and rotation of the rotor from a stopped position in the opposite direction retracts the elastomeric balls; and a detection device sending a trigger event to the micro-controller. The trigger event closes the elastomeric balls on the cigarette end, then reverses to release.
