Abstract (en)
[origin: EP0436826A2] Roll-changing devices used previously require replacement rolls, in which the adhesive tip is completely prepared, i.e. in which the adhesive for gluing the running web to the new roll has also been applied. In this case, the disadvantages are, on the one hand, the formation of a remaining tab when the old web is separated from the now running new web and, on the other hand, the time required for applying the adhesive, especially when the prepared roll cannot be used before the use-by date of the adhesive and therefore renewed adhesive tip preparation is required. <??>The roll-changing device according to the invention has an adhesive application device (6) which is arranged such that it applies an adhesive to be applied to the web (10) of the partially unwound roll (2). Furthermore, a blade (12) contained in a web pressing-on and separation device (5) of the roll-changing device is arranged such that no remaining tab is left after separation of the remaining web of the first roll from the now running second roll. <??>The invention can be used on all roll-changing devices. <IMAGE>
