The present invention relates to a linear movement device comprising at least two linear movement units (12, 14) which are guided in a movable manner along a shared linear movement axis (L), wherein the linear movement device (10) comprises a first linear drive (28) and a second linear drive (30), in such a way that each linear movement unit (12, 14) can be driven in movement along the linear movement axis (L) merely by the first linear drive (28), merely by the second linear drive (30), and also by both linear drives (28, 30) together, the first and the second linear drive (28, 30) being coupled to the linear movement units (12, 14) so as to transmit drive force, in such a way that when merely the first linear drive (28) or merely the second linear drive (30) is activated the linear movement units (12, 14) can be driven in movement in a shared direction along the linear movement axis (L) with a speed relative to one another, whereas when the first and the second linear drives (28, 30) are activated simultaneously all of the linear drive units (12, 14) can be driven at least in joint movement in the same direction along the linear movement axis (L) without any speed relative to one another. |
