A drive unit for driving a carriage which can be displaced along a transporting path comprises a barrel cam, which can be driven to rotate and has a drive groove for engagement of a driver arranged on the carriage, and also comprises a control device for controlling the drive of the carriage. The barrel cam has a first barrel portion and a second barrel portion, which is separate from the first, wherein the barrel portions can be driven independently of one another, and wherein the control device is designed so that, once the carriage has been received from a separate drive unit, it can accelerate the carriage with the first barrel portion and can supply the accelerated carriage to the second barrel portion.
