Embodiment Construction

[0028] In the figures, the same reference numerals designate corresponding parts and combinations of parts.

[0029] exist Figure 1 to Figure 3 In the example shown is a winder for winding a partial web comprising two winding rolls 10A, 10B. The partial webs are wound at the winding stations to partial web rolls respectively around cores 26A, 26B via winding nips formed between the partial web rolls 20A, 20B and the winding rolls 10A, 10B. 20A, 20B, these winding stations are arranged successively in the axial direction of the partial web roll 20A, 20B of each winding roll 10A, 10B. The partial web rolls 20A, 20B are supported at the ends of winding cores 26A, 26B by means of winding heads 13A, 13B. The winding machine comprises a core feeding system (not shown) and feeding beams 11A, 11B; the feeding beams 11A, 11B are used to feed new winding cores 25A, 25B into the winding machine, and in the previous set of sections During winding of the web rolls 20A, 20B close to the...

Abstract

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 around cores, in which method the partial web rolls are wound in winding stations on one or two winding rolls by a nip between the winding roll and the partial web roll be wound. In the method the new cores are transferred to the winding stations of the winder on feeding beams supported by support guides such that the cores are supported stationary on two fixed support points during movement of the feeding beams. 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 around cores, which winder comprises one or two winding rolls, which device comprises an arrangement for feeding cores into winding stations located on each winding roll, which winding stations comprise winding heads for supporting the ends of the cores during winding. The arrangement for feeding new cores to the winding stations comprises feeding beams with support guide for supporting the cores stationary on two fixed support points during movement of the feeding beams.

Description

technical field [0001] The invention relates to a method for winding a fibrous web in a winder, in particular for winding longitudinally slit paper and board webs into partial web rolls, in which method the partial web The roll is wound in the winding station by means of a nip formed between the wound partial web and the winding roll to wind the partial web roll. [0002] The invention also relates to an apparatus for winding fibrous webs in a winder, in particular for winding longitudinally slit paper and board webs into partial web rolls, wherein the apparatus comprises As for the winding stations for winding partial web rolls, these are formed in connection with one or two winding rollers. Background technique [0003] It is known that fibrous webs such as paper are manufactured in a plurality of machines which together form paper production lines up to several hundred meters in length. Modern paper machines are capable of producing over 450,000 tons of paper per year. ...
