Translation of "Flying splice" in German

This kind of a connection is called a flying splice.

Unexpectedly, the adhesive tape of the invention is outstandingly suitable for flying splice.

This widespread technique is also referred to as the flying splice or flying reel change.

One such device is known by the name "Flying Splice".

The adhesive tape of the invention can be used in particular for flying splice.

The Flying Splice unwinder allows fully automatic reel change for offline calendars.

The invention further provides a method of flying splice using an adhesive tape of the invention.

The invention relates to an optically detectable adhesive tape for flying splice of flat web material which has been wound to form rolls.

An upgrade of existing calender systems with Flying Splice allows more efficiency by increasing system capacity.

The fully automatic reel change with Flying Splice LS helps increase the capacity of offline calendars.

The Flying Splice unwinder is used for quicker, fully automatic winding and unwinding with offline calendars.

Taking place in the operation of the unwinding station 1 at a traveling speed of the material web up to 2000 m/min or more, the splicing of the material web 3 is also termed “flying splice.”

DE 196 28 317 A 1 and DE 196 32 689 A1 describe pressure-sensitive adhesive tapes constructed especially for flying splice in high-speed paper machines and comprising particularly readily cleaving paper as intermediate backing material for an integrated fixing aid of the leading edge.

Of these, the middle zone is non-adhesive, which has a number of disadvantages in practice, such as in the case of the actual flying splice, where it is the cause of jerkiness, but also in the case of winding to form a reel of such an adhesive strip, and, finally, also in the case of mechanized attachment.

In the case of a butt joint, a so-called flying splice, there is no need for this part to be cut out during subsequent working.

The invention relates to an adhesive tape for flying splice (flying reel change) and to a splice method using such an adhesive tape, especially in paper-converting machines, printing machines and the like.

Flying splice in papermills, film-producing plants or the like is a common technique for replacing an old, almost fully unwound roll of paper by a new roll without having to stop the machines, with run at high speed.

The invention relates to an adhesive tape for the flying splice (flying roll change) in paper finishing machines, rotary printing machines and the like, and to its use accordingly.

Flying splice in papermaking factories or the like is a common technique for replacing an old, almost fully unwound roll of paper by a new roll without having to stop the machines, which run at high speed.

The self-adhesive composition 3 is now exposed and is ready for this flying splice, in a width of 60 mm and over the entire width of the roll of paper.

However, the drawback with the previously known products and their use is that it requires considerable experience and skill on the part of the personnel in order that a reel, for example a paper reel weighing several tonnes and having a width up to 8 m, can be prepared uniformly and correctly in this way, in order to ensure a successful flying splice at speeds of several hundred metres per minute.

Flying splice in paper mills or the like is a common technique for replacing an old, almost fully unwound roll of paper by a new roll without having to stop the machines, which run at high speed.

There are various products on the market, known as tabs, for this butt splicing in flying splice, which in addition to a paper carrier are coated on both sides with a water-soluble self-adhesive composition.

It is an object of the invention to provide an adhesive tape for flying splice which minimizes the thickness in the region of the bond of the old web and the new web while retaining the complete ultimate tensile stress strength in order to accommodate the maximum web tension.

Thus, it has surprisingly and unexpectedly been found that the adhesive tapes were in the reverse of a splittable main carrier is provided only partially with a self-adhesive system are outstandingly suitable for flying splice without uncontrolled tearing of the main carrier material during the splicing operation.

Part of the self-adhesive face layer 3 is now exposed and represents the area of contact with expiring webs for the flying splice.

The advantage will be depicted here by way of example in comparison with a prior art adhesive tape for flying splice (cf., for example, DE 196 28 317 A1, DE 199 02 179 A1):

In the context of this method it is preferred that first of all only the smaller portion of the slitted liner is peeled away and the adhesive tape is bonded with the exposed portion of the self-adhesive composition behind the topmost web of a new roll of portion, while the larger portion of the liner is not peeled away until shortly before its use for the flying splice.
