Problems solved by technology

This is especially critical in cases where the user does not notice it, as the bond performance is reduced
If the user notices an initial tear, these tapes must be reapplied, which is time consuming and adversely affects productivity

Embodiment Construction

[0035] The adhesive tape (K) first consists of the main carrier (H) (in the Figure 1a and 1b not shown separately), on the front of the main carrier (O H ) with self-adhesive adhesive (M). Front side of tape (K) (O K ) and the front (O H ) on the same side (upper); the tape (K) and the back of the main carrier (U K , U H ) is also on the same side (underneath in each case) - for this see Figure 1c .

[0036] Figure 1a is a top view of this tape, whereby the front side (O K )lie in Figure 1a of the top. On the back of the tape (U K ) is a split system (TS) comprising multiple segments (S). exist Figure 1a In , this separation system (TS) is schematically indicated with dashed lines and only its course is shown (specifically, no segments are shown), since it is located underneath the tape, this area is not visible.

[0037] The tape can be wound into a roll (W), at which point the front side of the tape (K) (O K ) represents the appearance of each turn, the back...

Abstract

The invention relates to an adhesive tape for flying splice, having a left (l) and right (r) boundary edge, comprising at least one main carrier and a first layer of self-adhesive on the obverse (O) of the main carrier, the reverse (U) of the main carrier bearing a parting system (TS) which is suitable for effecting an adhesive bond to a substrate that can be parted again in such a way that sticky residues are left neither on the reverse of the main carrier (H) nor on the substrate in the region of the parted bond, the parting system (TS) being constructed in the form of a multiply interrupted stripe comprising a plurality of segments (S) that extends in the longitudinal direction of the adhesive tape (x direction), the individual segments (S) having less of an extent in the longitudinal direction of the adhesive tape (K) than the adhesive tape (K) itself, and the parting system (TS); being suitable for effecting the parting process, without the main carrier (H) being damaged in the course of that process.

Description

technical field [0001] The present invention relates to adhesive tapes for high speed splicing of flat webs wound into rolls, and also to on-the-fly splicing of flat webs wound into rolls at high speeds. Background technique [0002] When processing open web materials (paper, film, nonwovens, etc.), high-speed splicing is a common method of replacing old, almost completely unwound rolls with new rolls without stopping high-speed machinery for this purpose . During such on-the-fly roll changes, (pressure sensitive) adhesive tapes are often used to join (or bond) the end of the old web and the beginning of the new web. [0003] For many years, it has been known in this respect that some tapes are adhered in a straight line above or below the uppermost layer of the new roll and thus combine in one tape the function of roll closure and the function of the adhesive tape (the The tape joins the new web, more specifically the paper web, with the old, dying web). [0004] During ...
