Abstract

Method and device in a paper machine or a finishing machine for paper in order to spread out a threading strip R, which is cut from a full-width paper or cardboard web W, to a full-width paper web by means of inclined drawing. The inclined drawing cut Cv is performed by a mechanical cutter blade 13 or water jet. In the direction of advance of the web W that is to be cut ahead of its inclined drawing position, a jet S of water and/or steam is directed at the web W. In so doing, a wetting groove CM is Adrawn@ at the point for the cutting line, the said groove preventing cracks in the web W that deviate from the cutting line in inclined drawing. <IMAGE>
