Abstract

A method and a sealing device for sealing a joint ( 5; 31 ) between two end sides ( 3, 13 ) of two contiguous panels ( 1, 11 ). The method comprises the steps of: holding (S 1 ) an end side ( 3 ) of a first panel ( 1 ) close to an end side ( 13 ) of a second panel ( 11 ), whereby the joint ( 5; 31 ) to be sealed is defined by the adjacent end sides ( 3, 13 ) of the two panels ( 1, 11 ); sealing (S 3 ) the joint ( 5; 31 ) with a first and a second adhesive tape ( 15, 17 ) by providing a first tape ( 15 ) to a first face ( 19 ) of the two panels ( 1, 11 ), said first tape ( 15 ) sealing the joint ( 5; 31 ) and being provided in the direction of the joint and providing a second tape ( 17 ) to a second face ( 21 ) of the two panels ( 1, 11 ), wherein the second face ( 21 ) of the two panels ( 1, 11 ) is the opposite face to the first face ( 19 ) of the panels, said second tape ( 17 ) sealing the joint ( 5; 31 ) and being provided in the direction of the joint.

First claim

The invention claimed is:

1. A sealing device for sealing a joint between two end sides of two contiguous panels, said sealing device comprising:
a first part comprising a first tape dispenser arranged for providing a first adhesive tape to a first face of the two panels, said first tape sealing the joint and being provided in the direction of the joint when the two panels are passing through the sealing device; and
a second part comprising a second tape dispenser arranged for providing a second tape to a second face of the two panels, wherein the second face of the two panels is the opposite face to the first face of the panels, said second tape sealing the joint and being provided in the direction of the joint when the two panels are passing through the sealing device;
wherein said first and second parts of the sealing device are connected to each other such that the first and second tapes are provided simultaneously to the panels when the panels are passing between the first and second parts of the sealing device thereby sealing the joint from both faces of the panels, and
wherein the first and second parts of the sealing device are connected to each other by a transverse member such that the two panels to be joined can be passing between the first and second parts with the transverse member fitting in the joint, hereby there will be a distance between the two panels in the joint which distance corresponds substantially to a width of the transverse member.

2. Sealing device according to claim 1 , wherein the first and second tape dispensers each comprises a tape roll and an applicator roll, whereby tape from the tape roll is provided onto the panels by the applicator roll and the two applicator rolls will be provided close to each other allowing the two panels to pass between them whereby the first and second tapes will be provided to the panels while they are passing between the applicator rolls.

3. Sealing device according to claim 2 , wherein at least one of the applicator rolls is provided spring loaded such that by loading a spring the spring loaded applicator roll can be forced away from the other applicator roll thus allowing the panels to pass between the applicator rolls.

4. Sealing device according to claim 1 , further comprising a cutter arrangement arranged for cutting the two tapes at a certain distance from the panels.

5. Sealing device according to claim 4 , wherein the cutter arrangement is spring loaded and comprises an extending part arranged for sliding over a surface of the panels when they are passing through the sealing device, said extending part keeping a cutting part of the cutter arrangement in an inactive position as long as the extending part is in contact with the panels and when the panels have passed the sealing device and the extending part no longer is in contact with the panels the spring force will bring the cutting part into a cutting position where the two tapes are cut off.

6. Sealing device according to claim 1 , wherein at least one of the applicator rolls is driven by a motor which can be controlled in dependence of output from a sensor which can detect the presence of a panel in the sealing device.

7. Sealing device according to claim 1 , further comprising guiding wheels protruding into an opening between the first and second parts which opening the panels are passing through during sealing of the joint, said wheels being oriented for guiding the two panels towards each other during their passing through the sealing device.

8. A sealing device for sealing a joint between end sides of two panels, the sealing device comprising:
a first part comprising a first mounting surface and a first tape dispenser mounted on the first mounting surface, the first tape dispenser being configured to apply a first adhesive tape to a first face of the two panels to seal the joint; and
a second part comprising a second mounting surface and a second tape dispenser mounted on the second mounting surface, the second tape dispenser being configured to apply a second adhesive tape to a second face of the two panels to seal the joint; and
a transverse member connected between the first part and the second part, such that the end sides of the two panels can pass between the first and second parts with the transverse member disposed between the end sides of the two panels, such that a distance between the end sides of the two panels in the joint corresponds substantially to a width of the transverse member.

9. The sealing device of claim 8 , wherein the second face of the two panels is opposite to the first face of the two panels.

10. The sealing device of claim 8 , wherein the first and second parts are configured to apply the first and second tapes to the two panels in a direction generally parallel to the length of the joint.

11. The sealing device of claim 8 , wherein the first and second parts of the sealing device are configured to apply the first and second tapes to the two panels substantially simultaneously.

12. The sealing device of claim 8 , further comprising one or more guiding wheels protruding into an opening between the first and second parts, the opening being configured to have the end sides of the two panels pass therethrough during sealing of the joint.

13. The sealing device of claim 12 , wherein the one or more guiding wheels being oriented for guiding the end sides of the two panels towards each other as the end sides of the two panels pass through the sealing device.

14. The sealing device of claim 8 , further comprising a cutter arrangement configured to cut the first and second tapes at a certain distance from the two panels.

15. The sealing device of claim 14 , wherein the cutter arrangement is spring-loaded and comprises an extending part configured to slide over a surface of the two panels when the two panels pass through the sealing device, the extending part being configured to keep a cutting part of the cutter arrangement in an inactive position as long as the extending part is in contact with the two panels and when the two panels have passed through the sealing device and the extending part is no longer in contact with the two panels, the spring force being configured to bring the cutting part into a cutting position to cut the first and second tapes.

16. The sealing device of claim 8 , wherein each of the first and second tape dispensers comprises a tape roll and an applicator roll, the applicator roll being configured to apply tape from the tape roll onto the panels.

17. The sealing device of claim 16 , wherein at least one of the applicator rolls is spring-loaded to move the applicator roll away from the other applicator roll to allow for the two panels to pass through the sealing device.

18. A sealing device for sealing a joint between end sides of two panels, the sealing device comprising:
a first part comprising a first mounting surface and a first tape dispenser mounted on the first mounting surface, the first tape dispenser being configured to apply a first adhesive tape to a first face of the two panels to seal the joint; and
a second part comprising a second mounting surface and a second tape dispenser mounted on the second mounting surface, the second tape dispenser being configured to apply a second adhesive tape to a second face of the two panels to seal the joint;
a transverse member connected between the first part and the second part, such that the end sides of the two panels can pass between the first and second parts with the transverse member disposed between the end sides of the two panels, such
