A method for joining ends of fiber webs with a device comprising a tool element with a gripping device and a traversing punching device. A run of the fiber web from the emptying parent roll is moved to a joining position at the tool element. The trailing end of the parent roll fiber web is cut upstream from the joining position and the fiber web is attached to the tool element by a gripping device of the tool element. An end of a new roll fiber web is guided to contact with and to an overlapping position with the trailing end of the parent roll fiber. The traversing punching device is moved across the width direction of the fiber webs and makes at least one joint cut and joins the fiber webs. The new fiber web is cut downstream from the joint, and then tension control is turned on.
