Embodiment Construction

[0044] In the following description, similar names refer to similar components. It should be noted that the drawings are not drawn to scale and that they mainly serve the purpose of illustrating embodiments of the invention.

[0045] Figure 1-7 The shown fiber web production line comprises a fiber web machine, such as a paper machine 30 , and a turn-up device 10 in line with the paper machine 30 . On the reel-up 10 of the paper machine, the paper web W finished in the paper machine 30 is wound into a machine roll 12 around a reel shaft, ie, a reel roll 13, by means of a reel cylinder. The rolling device 10 advantageously comprises a transfer rail 40 ( figure 2 ) to the collection station 15 of the connected machine reel 12; the completed machine reel 12 is further transferred from the collection station 15 to the machine reel storage device 18, 18', 18", or at least one slitter rewinder 20A, 20B or not shown The backup station 16A, 16B of some other finishing machine that...

Abstract

A manufacturing line of a fibrous web (W) comprises a windup (10) of the fibrous web and at least one slitter-winder (2OA, 20B) or finishing machine and means for transferring machine reels (12) and / or winding shafts (13) to said windup and said at least one slitter-winder or finishing machine. In the manufacturing line, the direction of the manufacturing process of the fibrous web (W) is substantially reversed at 180 DEG after the windup (10) in relation to the process direction of the windup before the slitter-winder (20a, 20B) or finishing machine. The invention also relates to a method for manufacturing a fibrous web in a manufacturing line.

Description

technical field [0001] The invention relates to a fiber web machine such as a paper machine. More specifically, the invention relates to the production line of paper webs. Background technique [0002] As is known, paper is produced by a plurality of machines which together form a paper production line up to hundreds of meters long. Modern paper machines can produce more than 450,000 tons of paper per year. The speed of the paper machine can exceed 2000 m / min, and the width of the paper web can exceed 11 meters. [0003] In a paper production line, paper production takes place as a continuous process. In the paper machine, the finished paper web is wound into a machine roll by a rewinder around a reel, that is, a reel roll. The diameter of the machine roll can exceed 5m, and the weight of the machine roll is more than 160 tons. The purpose of rewinding is to change the finished flat paper web into a form that is easier to handle. On the rewinder, the continuous process ...
