Abstract
A packaging material sealing device, in particular cross seam packaging material sealing device for a vertical packaging machine, includes a first sealing jaw and at least a second sealing jaw, at least one movement unit for actuating the two sealing jaws along a sealing direction, and at least one control unit. In at least one operating state the control unit controls a rotation of the two sealing jaws relative to a transport direction of a packaging material. At least two guiding rails of the movement unit for moving the two sealing jaws along at least the sealing direction each have clearance with respect to their bearings in order to allow rotation of the two sealing jaws relative to the transport direction.

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).
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 the movement unit (20) comprises a first actuator (66) and at least a second actuator (68) for moving the two sealing jaws (16, 18) perpendicular to the sealing direction (30), 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 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′).
