Abstract
A web (P) is wound onto a core (17) while supported by a first carrier roll (11) and by a second carrier roll (12) and while a press roll (14) presses the web reel (13) that is being wound. The second carrier roll (12) is a carrier roll consisting of a set of belt rolls. The complete web reel is removed by means of a lowering device (15). During the lowering movement of the reel, a new core (17) is shifted into the gap between the first carrier roll (11) and the second carrier roll (12). The web (P) is cut off, and the cut-off end of the web (P) is attached to the core. The winding is slowed down to the exchange speed, nonstop, or to a stop, and the press roll (14) is raised off the complete reel (13) and shifted rearwards relative the complete reel (13). The set (12) of belt rolls is displaced in the lateral direction, and a new core (17) is shifted into the space defined the first carrier roll (11), the first roll (18) in the set (12) of belt rolls, and the complete reel (13). The set (12) of belt rolls is displaced back in the lateral direction, and the press roll (14) is displaced towards the new core (17), whereby the press roll (14) is, at the same time, positioned to push the complete reel (13) away from the first carrier roll (11). Substantially at the same time the second roll (19) in the set (12) of belt rolls is lowered in the vertical direction, whereby the complete reel (13) is positioned for transfer to the lowering device (15).
