1. A packaging material sealing device (12) comprising:
a first sealing jaw (16) and at least a second sealing jaw (18);
at least one movement unit (20) for actuating the two sealing jaws (16, 18) along a sealing direction (30); and
at least one control unit (32),
wherein the movement unit includes bearings (154, 156, 157, 158) and at least two guiding rails (150, 152) for moving the two sealing jaws (16, 18) along at least the sealing direction (30), wherein in at least one operating state the control unit (32) controls a rotation of the two sealing jaws (16, 18) about a horizontal axis (112) perpendicular to a transport direction (72) of a packaging material (14, 14′), wherein each of the at least two guiding rails (150, 152) of the movement unit (20) is mounted in at least two of the bearings (154, 156, 157, 158) in such a way that there is a clearance (164, 166) between the at least two guiding rails (150, 152) and the corresponding bearings (154, 156, 157, 158) in order to allow the rotation of the two sealing jaws (16, 18) about the horizontal axis (112).
