Abstract
The present invention relates to a sealing apparatus for sealing foil material, the apparatus comprising a foil conveying means and a sealing means including a sealing head which has at least one sealing position for performing the foil sealing operation, an intermediate position in which the sealing head has a predetermined distance from the sealing position, and an inoperative position in which the sealing head has a second predetermined distance from the sealing position that is greater than the first distance. Furthermore, the invention relates to a corresponding sealing method which can be carried out with the sealing apparatus, wherein the sealing head is removed from the foil material to a first distance during the further transporation of the foil material and is removed from the foil material to a second greater distance when the foil sealing operation is interrupted.
