Abstract (en)
[origin: WO9828216A1] The invention concerns a method of treating moving paper webs wherein, before transverse folding of the web along the cross-fold-line provided therein, a cross-groove is produced by means of a radially vibrating rail-like pressure tool and a counter pressure tool. In this way, a sharp folded crease can be produced in thick products in particular.
