摘要： The invention relates to a pressure unit (1) for sealing a package (2) for a food product, comprising a conveyor (3) for transporting the package (2) through the pressure unit (1) in a travelling direction (d), a first rotatable pressure roller (11) and a first rotatable anvil roller (21). The first pressure roller (11) is arranged opposite to the first anvil roller (21) to form a first nip (4) for receiving and rotationally engage with a portion (5) of the package, and arranged downstream of the first pressure roller (11) and the first anvil roller (21) in the travelling direction, a second rotatable pressure roller (12) and a second rotatable anvil roller (22). The second pressure roller (12) is arranged opposite to the second anvil roller (22) to form a second nip (6) for receiving and rotationally engage with the portion (5) of the package. The first anvil roller (21) and the second anvil roller (22), respectively, has a smooth rim surface (25). The first pressure roller (11) comprises a first bulge (15) extending annularly around its rim surface (18), the second pressure roller (12) comprises a second bulge (16) extending annularly around its rim surface (19), and the first bulge (15) is offset in relation to the second bulge (16) in an axial direction (7) of said first pressure roller (11) and the second pressure roller (12).
