Abstract

The invention relates to a method in connection with a change process of a reel-up of a fibre-web machine, which method is applied when performing a change of reeling of a web (W) from a web roll (11) being completed to a new web roll for reeling the next roll around a reeling shaft (12). In the method, for fastening the surface layer / surface layers of the web roll (11) to the web roll (11) beingcompleted, at least one two-sided tape (20) is adhered from its one side to the web (W) being passed to the web roll (11) being completed or to the surface of the web roll (11) and said tape (20) is adhered from its other side to the surface of the web roll (11) being completed / to the surface of the web (W) being reeled onto the web roll (11) being completed due to the effect of a reeling nip between the reel drum (13) and the web roll (11) or a pressing-roll nip between the web roll (11) and a pressing roll (14) or due to the effect of the tightness (T) of the web.

Description

technical field

[0001] The invention relates to a method according to the preamble of claim 1 . Background technique

[0002] It is known from the prior art that, in fiber web machines such as paper and board machines, coiling is used in relation to which fibrewebs (fibreweb) produced by fiber web machines such as paper / board machines Coiled onto machine rolls as a full width web for further processing. By surface pull in the take-up nip between the mandrel and the web roll being formed or by using a central drive, the web is wound up around a take-up shaft such as a reel / roll, whereby the take-up shaft is also set There are drives. In coiling, when a machine roll is about to be full, a roll change needs to be performed to start a new machine roll coil and the full machine roll needs to be removed from the coil. In the lap change process, the web is cut, whereby one end of the web is connected to a fully wound machine roll and the other end of the web is directed around a...
