Patent ID: 7348525

Claim:
A sealing jaw system comprising a sealing jaw, for manufacturing a transverse sealing seam ( 19 ) in the heat-sealable material for a package, where the heat sealable material has transverse crease lines 12 oriented in a direction that insects longitudinal crease lines 10 , said transverse crease lines being interrupted by gaps at a location where its direction passes a longitudinal crease line, and auxiliary crease lines 17 , 18 extending parallel to the direction of the transverse crease lines at least along the gaps, said sealing jaw having a sealing surface that is provided for coming into contact with the heat-sealable material, and at least one rod or bar-shaped heating device is provided on the sealing surface for heating the heat-sealable material, wherein at least one pressure element ( 23 ) is provided on the sealing surface, projecting above the sealing surface and at a distance from the heating device ( 22 ) and wherein the pressure element ( 23 ) is rod or bar shaped and extends substantially parallel to the heating device ( 22 ) and the pressure element ( 23 ) is adjustable for engagement with a fold line ( 10 , 11 ) running in a longitudinal direction relative to the pressure element and such that pressure element 23 extends along at least a portion of auxiliary crease lines 17 , 18 .
