Embodiment Construction

[0035] In the state of FIG. 1 a, a new reel serving as a new core 2 is in the roll change position, and a web of fibrous material W, such as a paper web, running to an old, already full roll, is in this position. connected, so this connection makes replacement possible. The winding core 2 contacts the web running on the surface of the web guide (coiling cylinder 1 ) in such a way that the winding core forms a changing nip N with the web guide and essentially in the same manner as the paper The running speed of the web rotates at the corresponding peripheral speed. After the change nip N between the winding core 2 and the take-up cylinder 1, the web moves on the surface of the web guide to the actual take-up nip, through which the web is wound on On a paper roll that gradually fills up. Hereinafter, the nip N refers to the nip formed in the replacement position, that is, the replacement nip.

[0036]The roll changing device shown in Fig. 1a comprises: cutting device 3, which...

Abstract

During a roll change in the winding process of the fibrous material web, the fibrous material web (W) running onto a full roll is removed by adhering the web to the surface of a new winding core (2) Change to run around a new core (2) in roll change position. The web (W) adheres to the surface of the core (2) by changing the properties of the material located on the surface of the core (2). The material is a combination of an adhesive area (6a) on the core surface and a protective layer (6b) on top of the adhesive area, and the properties of the material are changed by removing the protective layer (6b).

Description

technical field [0001] The invention relates to a method for changing laps in a coiling process of a web of fibrous material, for example in a paper or board machine, or in the finishing of paper or board, as described in the preambles of the appended independent claims The method of changing rolls in the coiling process of the device. In particular, the present invention relates to a method for changing rolls in continuous coiling without reducing the running speed. Background technique [0002] In the reeling of a paper machine, in so-called pope reeling or in center driven assisted reeling, the finished paper after passing through the calender is reeled around a core such as a mandrel. The coiling itself is carried out in such a way that the core is loaded against the means for guiding the web, namely the coiling cylinder, through which the web to be coiled travels and is wound around the core, thus forming The finished scroll. Coiling can be done by surface pull (coil...
