ABSTRACT:
A method and a device for threading the end of a web (P) from a jumbo roll (30) or equivalent through a winder along a path determined by members guiding the web (P). The end of the web (P) is passed from the jumbo roll (30) through the winder as a full width by grasping the end of the web (P) placed on the jumbo roll by means of a fetching and grasping device (13) and is held by means of the web (P) holding device (13). The web (P) is detached from the fetching and grasping device (11), attached to a threading member (22) carried by a carrier device (12), detached from the web (P) holding device (13), and threaded as a single thickness through the winder, whereby web (P) is unwound from the jumbo roll (30). The web (P) is cut off before the web (P) is attached to the threading member (22) carried by the carrier device (12).
