Embodiment Construction

[0040]If not stated otherwise, in the figures, the same reference numerals are used for parts and components that correspond to each other.

[0041] exist figure 1 with figure 2 Two different intermediate winders according to the prior art are shown in . The intermediate winder typically includes an unwinder 20 , an edge cutting unit 24 and a coiler 30 . The machine roll 15 to be processed in the intermediate winder is conveyed to the unwinder 20 and from there the web W is directed to an edge cutting unit 24 and then to a reel 30 comprising a winding drum 31. The winding shaft emptied by the unwinder 20 is lifted by means of the transport device 22 onto the winding shaft support 25 placed above the intermediate winder and on the track of the winding shaft support or correspondingly along the track The winding shaft 10 is transported for reuse on the coiler 30 . Adjacent to the edge cutting unit 24 is provided an operating platform 26 where the control personnel can obse...

Abstract

The invention relates to a fiber web winding machine, especially to an intermediate winding machine for fiber webs. The intermediate winding machine comprises an uncoiling unit (10), a winding shaft bearing (25), an extending roller (21) and a coiling unit (30), wherein the coiling unit (30) comprises a winding drum (31) for forming a winding roller gap between itself and a to-be-wound machine roll (15). The winding drum (31) for the coiling unit (30) of the intermediate winding machine has at least two positions substantially in the vertical direction, wherein one of the positions is a winding position, where the winding drum and the to-be-formed machine roll (15) form the winding roller gap.

Description

technical field [0001] The present invention relates to fibrous web machines, such as paper and board machines, in particular fibrous web finishing devices. The invention relates in particular to intermediate windings for fibrous webs and intermediate winding machines for fibrous webs. In particular the invention relates to a device for winding a fibrous web and a method for winding a fibrous web. Background technique [0002] Fibrous webs, such as paper or cardboard, are known to be produced in machines which together constitute a fibrous web production line, which can be several hundreds of meters long. Current paper machines can produce more than 450,000 tons of paper per year. The speed of the paper machine is typically 1200-1800 m / min, while the paper web width can exceed 11 meters. [0003] The production of fiber webs in a fiber web production line is realized as a continuous process. With the winder, the fibrous web to be produced in the fibrous web machine is wo...
