A device for detecting defects during sealing of a package comprising a foil, comprising:
- at least one distance sensor for determining the distance between at least two relatively displaceable clamping elements for pressing against each other the foil and another part of the package to be attached to the foil, and
- at least one control unit coupled to the at least one distance sensor for comparing the measured values collected by the distance sensor to predefined reference measured values for a period during displacement of the clamping elements toward each other.
A method for detecting defects during sealing of a package comprising a foil, comprising:
- positioning a foil and another of part of a package to be connected to the foil between at least two clamping elements,
- moving the clamping elements toward each other, wherein a connection between the foil and the other part of the package is formed,
- moving the clamping elements apart, and
- removing the package relative to the clamping elements, wherein the distance between the clamping elements is determined for a period during displacement of the clamping elements moving toward each other and, wherein the collected measured values are compared to predefined reference values.
