Description
PAS AID DEVICE FOR RE~TG A PAPER V7EB
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. In addition, the invention 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 and a reel drum.
Processes and devices are known in which the tail feed strip is reeled onto a reel spool or a winding tube, on or to which an adhesive or an adhesive strip has been applied manually over the entire web width. An automatic adhesive application device is known from AT 406 255. The adhesive can also be applied to the paper web ahead of the reel spool using spray nozzles. In these known processes, only a tail strip is wound onto the reel first of all, thus causing unevenness when the paper web then becomes broader to extend over the machine width. In addition, air entrapment may occur, which can cause the web to run off track.
Due to the unevenness over the web width, particularly the equipment for measuring the web tension and corresponding control device (winding tightness control) can no longer be used.
The aim of the invention is thus to transfer the full web width onto the reel spool or winding tube when feeding in the web or after a web break. This method can also reduce the amount of broke.
According to the invention, this is achieved by pressing the paper web tail or the entire width of the web onto the reel drum and securing it there by means of an auxiliary roll before it is transferred to the reel spool. In this way, the web tail or the entire web width can run over the reel drum without the disadvantages of having to be wound onto the reel spool.
An advantageous further development of the invention is characterised by the auxiliary roll being at a standstill, however it can also be operated in creep mode or accelerated to and then operated at production speed.
Thus, the paper web tail can be placed easily over the reel drum when first fed in after a shutdown and can also be inserted again quickly after a web brea k.
A favourable embodiment of the invention is characterised by the paper web tail being diverted into a puiper after the reel drum until the web has the required width. This provides a favourable means of transferring the web in its the entire width.
A particularly favourable further development of the invention is characterised by an adhesive being applied to the reel spool so that the full width of the web can be transferred instantly to the reel spool. With this step, the entire web can be wound directly onto the reel spool without unevenness occurring at the edges.
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 and a reel drum. According to the invention, this device is characterised by an auxiliary roll being provided in addition to press a paper web tail or the entire web width onto the reel drum and secure it there.
If the auxiliary roll has a design that is suitable for pressing onto the reel drum, the paper web can be secured to the reel drum particularly well.
If the auxiliary roll is designed such that it can be lifted off the reel drum, this will prevent anything from influencing normal production operations.
If the auxiliary roll has a drive to accelerate to production speed, transfer of the paper web tail or the entire web width can be performed particularly favourably until the web is received on the reel spool.
If a device is provided for applying adhesive to the reel spool, the entire web width can be transferred particularly well to the reel spool without any unevenness over the web width. This results in a sharp drop in the amount of broke.
The invention will now be described in examples and referring to the drawings, where Fig. 1 shows a state-of the-art reeling device, Fig. 2 contains a schematic diagram of the invention feeding in the web tail, Fig. 3 a schematic diagram of the invention with the web being transferred to the reel spool, and Fig. 4 a schematic diagram of the invention in continuous winding operation.
Figure 1 now shows the arrangement of a reeling device 1 for a paper machine, particularly a tissue machine, where the paper is wound onto a reel 2. The empty reel spool 3 has a rubber covering or is fitted with a core shaft 3' and brought from a storage area into position 3" to a reel drum 5 using a lever 4. From there, the reel spool 3 is swung in direction 6 towards the full reel, where the paper is cut over the entire width in continuous operation, and reeling continues immediately onto the empty reel spool 3. This embodiment has an adhesive applying device 7 mounted above the storage position for the empty reel 3 to apply adhesive to the empty core shaft 3'.
Figure 2 shows the invention with a paper web tail 8 being fed to a reel drum 5. A web guiding device is used to feed the paper web tail into the space between the reel drum 5 and the auxiliary roll 9, where the auxiliary roll 9 is either at a standstill, or running at creep or any other desired speed. Subsequently, the auxiliary roll 9 is pressed onto the reel drum 5 and thus secures the web tail 8. After leaving the reel drum 5, the web tail 8 is diverted into a pulper (not shown). This is where web widening begins, i.e. the web tail broadens until it reaches the full web width. Then it can be cut lengthwise in one or more places using a slitter. At the same time, an empty reel spool 3 (position 3a) from the reel spool magazine is brought to the reel spool lift (lever 4) and adhesive 10 is applied to the reel spool 3 (in position 3b) using an adhesive applying device 7. As an alternative, an adhesive strip can also be applied over the entire web width.
The reel spool is then placed in the primary arm of the winder 1 using the reel spool lift.

This embodiment has an adhesive applying device 7 mounted above the storage position for the empty reel 3 to apply adhesive to the empty core shaft 3'.
Figure 2 shows the invention with a paper web tail 8 being fed to a reel drum 5. A web guiding device is used to feed the paper web tail into the space between the reel drum 5 and the auxiliary roll 9, where the auxiliary roll 9 is either at a standstill, or running at creep or any other desired speed. Subsequently, the auxiliary roll 9 is pressed onto the reel drum 5 and thus secures the web tail 8. After leaving the reel drum 5, the web tail 8 is diverted into a pulper (not shown).

As an alternative, an adhesive strip can also be applied over the entire web width.
The reel spool is then placed in the primary arm of the winder 1 using the reel spool lift.
Figure 3 illustrates the status when the entire web 8 is transferred to the reel spool 3. The reel spool 3 is brought to machine speed in position 3c and then pressed onto the paper web 8 running over the reel drum 5 in position 3d. At the same time, the entire web is detached instantly, i.e.
within a fraction of a second, and wound immediately onto the reel spool 3.
Since the paper web widens on the reel drum 5 from the web tail to the full web width during the start-up procedure, and also after a web break should the situation arise, the web can also be transferred to the reel spool right away with its full width and need not be allowed to widen during winding on the reel spool, as was the case to date, which would lead to the unevenness and problems described above.
Figure 4 then shows the situation during continuous winding of the paper web 8 onto the reel 2, where the auxiliary roll 9 is lifted off the reel drum here and thus, there are no obstacles for the paper web.
The invention is not limited to the variants shown. It can be used in any paper machine, but does bring advantages in tissue machines because it is particularly important here to have even web distribution over the web width and because, due to creping, there is also a particular risk of air entrapment between the layers of the paper web on the core shaft, which could thus cause web displacement. There are various possibilities for transferring the web to the reel spool, where the embodiment with adhesive and instant transfer of the entire paper web is particularly advantageous.
