Transfer system for transferring items, such as parts of a simulated smoking device, which transfer system comprises a first transfer device for receiving the items, a second transfer device for discharging the items, and a buffer device for buffering items between the first transfer device and the second transfer device, wherein; - the first transfer device comprises a first transfer rotator rotatable about a fixed first transfer axis and provided with first transfer holders configured to hold the items, which first transfer holders are arranged in a first circular transfer arrangement around the first transfer axis, - the second transfer device comprises a second transfer rotator rotatable about a fixed second transfer axis and provided with second transfer holders configured to hold the items, which second transfer holders are arranged in a second circular transfer arrangement around the second transfer axis, - the buffer device comprises at least two buffer rotators, each buffer rotator being rotatable about a respective buffer axis which is movable along a predetermined buffer trajectory, and each buffer rotator being provided with buffer holders configured to hold the items and arranged in a circular buffer arrangement around the buffer axis, - the at least two buffer rotators are positioned one after the other, neighbouring buffer rotators being arranged near each other in a respective buffer region to transfer the items from one of the buffer rotators of said neighbouring buffer rotators to the other, - the buffer device is configured to hold the buffer axes of neighbouring buffer rotators at a respective constant buffer distance during their movement along their buffer trajectory, - the at least two buffer rotators comprise a first buffer rotator having a first buffer axis which is movable along a first buffer trajectory and a last buffer rotator having a last buffer axis which is movable along a last buffer trajectory, - the first transfer rotator is arranged near the first buffer rotator in a first transfer region to transfer the items from the first transfer rotator to the first buffer rotator, and the last buffer rotator is arranged near the second transfer rotator in a second transfer region to transfer the items from the last buffer rotator to the second transfer rotator, - the first buffer trajectory defines a first part of a first circle having a first centre coinciding with the first transfer axis, - the last buffer trajectory defines a second part of a second circle having a second centre coinciding with the second transfer axis, and - the transfer system is configured to adjust at least one of a first transfer speed of the first transfer rotator and a second transfer speed of the second transfer rotator. - the first transfer device comprises a first transfer rotator rotatable about a fixed first transfer axis and provided with first transfer holders configured to hold the items, which first transfer holders are arranged in a first circular transfer arrangement around the first transfer axis, - the second transfer device comprises a second transfer rotator rotatable about a fixed second transfer axis and provided with second transfer holders configured to hold the items, which second transfer holders are arranged in a second circular transfer arrangement around the second transfer axis, - the buffer device comprises at least two buffer rotators, each buffer rotator being rotatable about a respective buffer axis which is movable along a predetermined buffer trajectory, and each buffer rotator being provided with buffer holders configured to hold the items and arranged in a circular buffer arrangement around the buffer axis, - the at least two buffer rotators are positioned one after the other, neighbouring buffer rotators being arranged near each other in a respective buffer region to transfer the items from one of the buffer rotators of said neighbouring buffer rotators to the other, - the buffer device is configured to hold the buffer axes of neighbouring buffer rotators at a respective constant buffer distance during their movement along their buffer trajectory, - the at least two buffer rotators comprise a first buffer rotator having a first buffer axis which is movable along a first buffer trajectory and a last buffer rotator having a last buffer axis which is movable along a last buffer trajectory, - the first transfer rotator is arranged near the first buffer rotator in a first transfer region to transfer the items from the first transfer rotator to the first buffer rotator, and the last buffer rotator is arranged near the second transfer rotator in a second transfer region to transfer the items from the last buffer rotator to the second transfer rotator, - the first buffer trajectory defines a first part of a first circle having a first centre coinciding with the first transfer axis, - the last buffer trajectory defines a second part of a second circle having a second centre coinciding with the second transfer axis, and - the transfer system is configured to adjust at least one of a first transfer speed of the first transfer rotator and a second transfer speed of the second transfer rotator.
