Method and device in a winder for webs, in particular feeding new cores to a winder

The invention relates to a method in a winder for winding fiber webs, particularly for winding longitudinally slitted paper and board webs into partial web rolls (20A, 20B) around cores (26A, 26B), in which method the partial web rolls (20A, 20B) are wound in winding stations on one or two winding rolls (10A, 10B) by a nip between the winding roll (10A, 10B) and the partial web roll be wound (20A, 20B). In the method the new cores (25A, 25B) are transferred to the winding stations of the winder on feeding beams (11 A, 11 B) supported by support guides (12A, 12B) such that the cores (25A, 25B) are supported stationary on two fixed support points during movement of the feeding beams (11 A, 11 B). The invention also relates to a device in a winder for winding fiber webs, particularly for winding longitudinally slitted paper and board webs into partial web rolls (20A, 20B) around cores (26A, 26B), which winder comprises one or two winding rolls (10A, 10B), which device comprises an arrangement (11 A, 11 B) for feeding cores (25A, 25B) into winding stations located on each winding roll (10A, 10B), which winding stations comprise winding heads (13A, 13B) for supporting the ends of the cores (26A, 26B) during winding. The arrangement for feeding new cores (25A, 25B) to the winding stations comprises feeding beams (11A, 11 B) with support guide (12A, 12B) for supporting the cores (25A, 25B) stationary on two fixed support points during movement of the feeding beams (11 A, 11 B).
