Abstract
A method and device for threading a paper web or an equivalent web-like material in a winding device, in particular in a slitter-winder, in which the paper web or the equivalent web-like material is wound from a web reel or equivalent onto another roll. A threading wedge is formed into the paper web or equivalent web-like material and passed through the winding device. Substantially at the same time as the web reel is unwound, a threading wedge narrower than the width of the web is separated from the web by a wedge-making device/devices and the web is passed by threading devices through the winding device. The arrangement includes members for winding the paper web or equivalent web-like material from the web reel or equivalent onto another roll, a pulling device or equivalent for unwinding the web from the web reel, a wedge-making device/devices for cutting the threading wedge substantially at the same time from the web and threading devices for passing the threading wedge through the winding device substantially at the same time.
