Abstract

An adhesive tape for a flying reel change of a flat material wound up over a reel, provided with at least one detachable adhesive system. The adhesive tape is provided with at least one transponder which can be detected by means of a detector.

Claims

1. A splicing method for the flying reel change of flat web material wound up on reels, said method comprising the following steps:

a) providing an adhesive tape comprising a cleavable adhesive system and a transponder;

b) adhering an uppermost web of a new reel with the adhesive tape to a web lying underneath said uppermost web;

c) exposing a portion of said adhesive tape intended to be spliced to an old unwinding reel to be replaced;

d) placing the new reel beside the old unwinding reel;

e) accelerating the new reel to a rotational speed that is substantially the same as that of the old unwinding reel;

f) determining the exact time that the new reel is to be pressed against the old unwinding reel to effect a splice of the new reel to the old unwinding reel by detecting the transponder; and

g) pressing the rotating new reel against the old unwinding reel at said exact time, wherein the adhesive tape bonds to the old unwinding web to effect the splice, while at the same time the cleavable system cleaves in such a way that no adhesive regions of the cleavable system are exposed afterwards.

2. The method according to claim 1, wherein the adhesive tape comprises a main carrier and the main carrier comprises a transponder.

3. The method according to claim 1, wherein the transponder is a thin-layer transponder.

4. The method according to claim 1, wherein the web material comprises paper.
