ABSTRACT:
Method for sealing a tear-off foil (16) onto a packaging element (12) including a sealing step in which the packaging element (12) is conveyed in a direction of transport (A) and, by a sealing stroke crosswise to the direction of transport (A), is moved towards a stamp tool (28) carrying punched-out foil (16), and is pressed against punched-out foil (16), with punched-out foil (16) and packaging element (12) being sealed together under the influence of heat, and in which the sealing step is preceded by a heating step in which packaging element (12) is heated by non-contact arrangement to at least the temperature required for subsequent sealing, and in that during the sealing step, stamp tool (28) carrying punched-out foil (16) is moved towards packaging element (12) by a feed stroke executed counter to the sealing stroke.
