System for performing a processing step on cigarette parts of an electronic cigarette, said system comprising; - a transport device comprising multiple holding units for holding the cigarette parts, wherein the holding units are positioned at a holding distance from each other while forming a circular configuration, and the transport device comprises a transporter drive by which the holding units are moved at a speed in a rotation direction along a circular trajectory having a centre, - a supply unit which places the cigarette parts in the holding units of the transport device at a receiving location along the circular trajectory so that the cigarette parts are transported along at least part of the circular trajectory, - a discharge unit which removes the cigarette part from the holding units at a discharge location along the circular trajectory, - a pivot device comprising multiple processing units positioned along at least a part of the circular trajectory at a process distance from each other which corresponds with the holding distance between the holding units so that the processing units can be associated with the cigarette parts held by the holding units, wherein; -- the pivot device is pivotable about a pivot axis extending through the centre of the circular trajectory, -- the pivot device comprises a pivot drive to alternately pivot the processing units from a first radial position to a second radial position in a first pivot direction parallel to the circular trajectory and in the rotation direction of the transport device and synchronously with the cigarette parts transported by the transport device and subsequently back from the second radial position to the first radial position in a second pivot direction parallel to the circular trajectory and opposite to the rotation direction of the transport device, -- in the first radial position, each processing unit is positioned in an associated position relative to one of the cigarette parts held by the holding units of the transport device, and -- each processing unit performs the processing step on the cigarette part associated with said processing unit while the pivot device pivots from the first radial position to the second radial position synchronously with said associated cigarette parts. - a transport device comprising multiple holding units for holding the cigarette parts, wherein the holding units are positioned at a holding distance from each other while forming a circular configuration, and the transport device comprises a transporter drive by which the holding units are moved at a speed in a rotation direction along a circular trajectory having a centre, - a supply unit which places the cigarette parts in the holding units of the transport device at a receiving location along the circular trajectory so that the cigarette parts are transported along at least part of the circular trajectory, - a discharge unit which removes the cigarette part from the holding units at a discharge location along the circular trajectory, - a pivot device comprising multiple processing units positioned along at least a part of the circular trajectory at a process distance from each other which corresponds with the holding distance between the holding units so that the processing units can be associated with the cigarette parts held by the holding units, wherein;
