Abstract: A joint and device for joining ends of at least two fiber webs together, the joint being formed of at least one cut provided to penetrate through the ends of the fiber webs in an overlapping position, which cut has at least one side part and from the side part extending at least one substantially straight part and which cut, which forms at least one flap, being configured to remain attached to the fiber webs by at least one folding line substantially aligned with the direction of the movement of the fiber webs. The device comprises a tool with a cutting edge and a counter element with a groove and located on the opposite side of the fiber webs, and the tool protrudes into the groove. The groove has a greater cross-sectional area than the cross-sectional area of the tool such that a loose and spacey fitting is provided.
