Abstract (en)
[origin: WO9925547A1] A method of joining together at least two paper sheets (1, 2). The method comprises the steps of moistening each paper sheet (1, 2) with a determined amount of water within the region of the intended join (9); placing the paper sheets together with the moistened regions in abutment with one another; and processing the moistened regions of the combined paper sheets in an ultrasound welding device (7, 8) such that at least 80 percent by weight of the water applied will be removed. The invention also relates to apparatus for carrying out the method and to a join produced by means of said method.
