Abstract A method and a device for cutting an edge strip in a web by means of a water jet against a felt or wire of a paper machine for the threading of the web, whereby the end of the web is passed through the paper machine by means of the edge strip cut in the web, the edge strip being narrower than the web. In order to prevent the felt or wire from getting wet or being choked, the waker jet is displaced back and forth across the di- rection of travel of the web so that the water jet cuts a gently wavelike edge in the edge strip. Corre- spondingly, the water used in the cutting and the filling agent or other such waste possibly separated from the web spread over the web over a wider area in- stead of spreading linearly, whereby the felt or wire will not get wet or choked.
