The invention relates to a method for winding of partial webs, in which method the partial webs are wound around cores (31; 31 L", 31 R") to partial web rolls (35L, 35R) as set in winding stations by a nip between a winding roll and the partial web roll being formed in a multistation type winder, which comprises one or two winding rolls (35L, 35R) and arrangement for feeding cores (31; 31 L, 31 R; 31 L', 31 R') into the winder. In the method the cores (31; 31 L, 31 R; 31 L', 31 R') for one set are moved into the winder in pairs (31 L, 31 R; 31 L', 31 R') by a core pusher (21) that pushes two adjacent cores (31 L, 31 R; 31 L', 31 R') into the winder simultaneously and that the cores (31 L, 31 R; 31 L', 31 R') are positioned one at time to a location for pick up to the winding stations and that in the method in case of uneven number of cores (31; 31 L, 31 R; 31 L', 31 R') needed for winding a set of partial web rolls (35L, 35R) one core is moved and located at time. The invention also relates to a device in a winder for winding of partial webs in a multistation type winder, which comprises one or two winding rolls on which winding stations are provided for winding the partial webs around cores (31; 31 L", 31 R") to partial web rolls (35L, 35R) as set in the winding stations by a nip between the winding roll and the partial web roll being formed, which device comprises an arrangement for feeding cores (31; 31 L, 31 R; 31 L', 31 R') into the winder. The arrangement comprises a core pusher (21) for pushing one or two adjacent cores (31 L, 31 R) at time into the winder and for locating the cores (31 L, 31 R) in the winder to be picked up to the winding stations on the winding rolls. |
