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 (S1) 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 (S3) 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.

Dependent claims

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.
