Patent ID: 7665276

Claim:
An apparatus for sealing a package, comprising a sealing unit and an abutment between which a number of material layers are disposed to be clamped and sealed and fused together, the abutment is connected to at least one elongate element which extends in a direction from the abutment towards and past the sealing unit, the at least one elongate element, beyond the sealing unit is disposed to be connected to at least one first operating element, and an operating unit is disposed to apply a force between the sealing unit and said first operating element so that the sealing unit and the first operating element are displaced in a direction from one another and so that the abutment and the sealing unit are displaced in a direction towards one another, wherein the force from the operating unit is applied to the sealing unit by the intermediary of a second operating element comprising at least one force-restricting coupling member which is disposed to restrict force between the second operating element and the sealing unit and thereby force between the abutment and the sealing unit, and wherein the at least one force-restricting coupling member is disposed between the sealing unit and the first operating element.
