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.
Claims20
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 in at least one operating state the control unit (32) controls a rotation of the two sealing jaws (16, 18) relative to a transport direction (72) of a packaging material (14, 14′), wherein at least two guiding rails (150, 152) of the movement unit (20) for moving the two sealing jaws (16, 18) along at least the sealing direction (30) each have clearance with respect to their bearings (154, 156, 157, 158) in order to allow rotation of the two sealing jaws (16, 18) relative to the transport direction (72).
A packaging material sealing device (12) comprising:

- 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 (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 at least two guiding rails (150, 152) of the movement unit (20) for moving the two sealing jaws (16, 18) along at least the sealing direction (30) each have clearance with respect to their bearings (154, 156, 157, 158) in order to allow rotation of the two sealing jaws (16, 18) relative to the transport direction (72).
