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 supply system (not shown) and supply beams 11A, 11B; the supply beams 11A, 11B are used to supply 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 and apparatus for winding a fibrous web in a winder for winding a longitudinally slit paper and board web around a mandrel into partial rolls; wherein said The partial web roll is wound on one or two winding rolls in the winding station by means of the nip between the winding roll and said partial web roll being wound; Transfer to the winding station of the winder so that the cores are supported statically on two fixed support points; where new cores are transferred on a feed beam to the The winding station of the winding machine, such that the winding core is supported stationary on the two fixed support points during the movement of the feeding beam; and such that the feeding beam for supporting the winding core is moving near the winding station so that the winding cores are picked up to the winding station and the winding head of the winding station picks up the winding cores directly from the feed beam.

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. ...
