Abstract

A sealing member comprising a sealing section configured to interact with a sealing band of a tube of packaging material in a sealing stage, and a package volume controlling section configured to interact with a first area next to the sealing band of said tube of packaging material in the sealing stage, wherein said package volume controlling section is provided with a socket for holding an insert.

Claims

1. A sealing member comprising:

a sealing section configured to interact with a sealing band of a tube of packaging material in a sealing stage, and

a package volume controlling section configured to interact with a first area next to the sealing band of said tube of packaging material in the sealing stage,

wherein said package volume controlling section is provided with a socket for holding an insert,

wherein the socket is provided with socket protrusions for holding the insert in place,

wherein the socket protrusions extend in a sliding direction perpendicular to a surface normal of said package volume controlling section, and

wherein the socket is arranged for receiving the insert via a section placed opposite to the sealing section.

5. The sealing member according to claim 1, further comprising

a tube controlling section configured to interact with a second area next to the sealing band, wherein the first area and the second area are placed on each sides of the sealing band in the sealing stage,

wherein the tube controlling section is provided with an additional socket for holding an additional insert.

6. The sealing member according to claim 1, wherein the sealing member further comprises an inductor.

7. An insert comprising:

a convex portion configured to interact with the first area of a tube of packaging material in a sealing stage,

a first section configured to be placed in the socket, and

a second section placed on top of the first section and placed off set the first section,

wherein the insert is configured to be held in a socket of a sealing member according to claim 1.

8. The insert according to claim 7, wherein the insert is provided with insert protrusions configured to interact with socket protrusions of the socket.

9. The insert according to claim 7, wherein the insert is configured to be held in the socket of the package volume controlling section.

11. A sealing apparatus comprising a first sealing member and a second sealing member, wherein the first sealing member is provided with an inductor and an active surface of the sealing section, and the second sealing member is provided with at least one pressure pad for providing a counter-pressure in the sealing stage, and wherein the first sealing member and the second sealing member both comprising a package volume controlling section provided with a socket holding an insert according to claim 7.
