Problems solved by technology

In these known methods only the tail tape is first wound onto the reel, thus causing inhomogeneities when the web widens to extend across the full machine width
In addition, trapped air can also occur, which can cause the web to derail

Embodiment Construction

[0020] figure 1 Shown is the arrangement of a winding device 1 of a paper machine, in particular a textile machine, in which a paper web is wound onto a reel 2 . An empty reel 3 with a rubber cover or fitted with a mandrel 3' is brought from the storage area to position 3" with a lever 4 to the reel 5. From there, the reel 3 is swung in direction 6 towards the entire reel, where The paper is cut across the entire width in a continuous operation and the paper is rapidly continued to be wound onto the empty reel 3. This embodiment has an adhesive application device 7 for the empty reel 3 mounted above the storage position, to apply adhesive to the empty mandrel 3'.

[0021] Figure 2 shows a web tail 8 being fed to a reel 5 in the present invention. The web guiding device is used to feed the web tail into the space between the mandrel 5 and the auxiliary roll 9, which is either stationary or running at a creeping or other desired speed. Subsequently, the auxiliary roll 9 is pr...

Abstract

The invention relates to a process for reeling a paper web, particularly a tissue web, specifically when starting up the machine and after a web break. According to the invention, this is achieved by pressing the paper web tail 8 or the entire width of the web onto the reel drum 5 and securing it there by means of an auxiliary roll 9 before it is transferred to the reel spool 3. The invention also relates to a device for reeling a paper web, particularly a tissue web, specifically when starting up the machine and after a web break, using a reel spool 3 and a reel drum 5. Here, an auxiliary roll 9 is provided in addition to press a paper web tail 8 or the entire web width onto the reel drum 5 and secure it there.

Description

technical field [0001] The present invention relates to a method of winding a paper web, especially a tissue web, especially at machine start-up and after the web breaks. In addition, the invention relates to an apparatus for winding a paper web, especially a tissue paper web, with reels and mandrels, especially at machine start-up and after fabric breakage. Background technique [0002] Methods and apparatus are known for winding tail-fed strips onto reels or tubes on which adhesive or adhesive tape is manually applied across the width of the paper web. An automatic adhesive application device is known from AT 406 255 . It is also possible to use nozzles to apply the adhesive to the web in front of the roll. In these known methods, only the tail tape is first wound onto the reel, thus causing inhomogeneities when the web is widened to extend across the entire machine width. Additionally, trapped air can also occur, which can cause the web to derail. [0003] Due to the ...
