Grip strips for self-adhesive tapes

The invention relates to a grip strip for self-adhesive tapes, especially for transparent, self-adhesive strips.

It is known that self-adhesive tapes wound into rolls with thin carriers, in particular, are used for the first time those made of plastic foils, it is often difficult to see the beginning of the adhesive tape that is stuck to the following turn • and to be replaced.

It has therefore been proposed that the tape end to the adhesive side to fold over so that a non-adhesive end of the tape is formed. For this, for example, according to the German Patent specification 1 014-253 a support bracket provided with a recess used. In this way, the end of the tape is made tack-free, but a visible marking for quick location the end of the tape is missing.

It has also already been proposed to improve the adhesiveness by applying covering agents such as fillers, wax powder and pick up color pigments. However, these methods cannot be carried out without difficulty and are related to the The production of single rolls is often uneconomical.

Furthermore, from the German patent specification 1 04-3 556 a Known separation process according to which the cut edges are colored at the same time as a base is cut. In this way the end of an adhesive tape can be given an optical mark,

- 2 but not made tack-free.

According to the German utility model 1 65> 4 617 is also already a V-shaped folded double flap has been proposed, which is releasably glued to the end of the adhesive tape. This double flap must but can be placed on every single cut tape end and therefore leads to high costs in industrial production.

It is also known to apply a colored paper sheet to the end of the adhesive tape to form part of the adhesive surface to cover and in this way to form a visually striking flap that can be easily grasped. To such a one Grab strips, a paper strip is glued in the transverse direction over a wide strip of self-adhesive film, which are then cut with the paper in the longitudinal direction into a multitude of individual strips of the desired width and on each one Cores is wound into rolls. The paper strip must be applied in such a way that it has the tack-free end a rolled up adhesive strip of a certain length forms when the plurality of individual adhesive tapes through a cut is separated transversely to its running direction over the entire width of the not yet divided web.

Only when this cross-section is made exactly at the outer edge of the paper strip does the strip form with its full length Spread the end of the rolled up tape. But such a careful cut takes a lot of time. This makes it special then very annoyingly noticeable when a web is cut into many adhesive strips of small length and width got to.

Often this cross-section is therefore in the area of the paper strip, so that a remnant of this colored strip is stuck to a new core as the beginning of a new adhesive tape. at For largely clear and transparent films and cores, this conspicuous scrap of paper is an ugly sight and can

in the case of rolls with a low number of turns, this can even lead to confusion with the free end of the tape.

To avoid this disadvantage, the adhesive tape is placed at some distance behind the paper strip in the area of the new roll If the part belonging to the beginning is cut off, a sticky end of the tape is created behind the non-sticky zone, with which the covered zone becomes stuck on the roll and loses its function.

The object of the invention is to avoid the disadvantages mentioned and to provide a grip strip in particular for such self-adhesive tapes to create that are clear and / or wound on clear cores. This also applies accordingly to Cores or ribbons that are so little colored or matted that a colored or otherwise marked one Grip strip shines through. In addition, this grip strip is intended to enable rapid cutting of the webs and tracks equipped with it Allow tapes using standard time-saving methods.

According to the invention, this object is achieved by a grip strip for self-adhesive tapes, which is characterized in that it is colored, patterned and / or labeled with a limited area and has a longitudinally extending colorless and transparent zone, the outer lateral boundary of which the edge of the grip strip forms.

For the combination with the adhesive tape, the grip strip is in such a way transversely to the running direction of the one to be cut Web of self-adhesive material placed on the adhesive surface that the colorless zone facing away from the roll of tape at the end of the Adhesive tape lies and the cross section that separates the rolled up tape from the web takes place in the area of this colorless zone. The end of the tape, which is non-sticky in its entirety, is thus formed by the colored or otherwise marked part of the grip strip and the colorless zone adjoining the outside at the end, which is generally narrower due to the gate.

The grip strip according to the invention is characterized in that only an inconspicuous, practically invisible section this strip after a cross-section which is unproblematic in terms of accuracy as the beginning of another adhesive tape on the core winding the following roll of tape. It is therefore particularly suitable for use with colorless and largely clear see-through tapes.

This colorless grip part can analogously, particularly in the case of adhesive tapes which are colored or matted to a lesser extent have a weak, appropriately similar shade or matt finish and still be inconspicuous. Such The specialist can vote at any time.

Since the entire width of the colorless grip part, for example several millimeters, is available for a cross section Much higher cutting sequences are possible than when using colored paper strips, which have a precise cross-section along their edge and thus always require tedious adjustment work on the cutting device.

The grip strip according to the invention can expediently consist of such flexible film-like or foil-like plastics or modified natural materials that are sufficiently colorless, are transparent and clear. Patterns, markings and colors can be done, for example, by embossing, printing or impregnating or mixing in suitable materials to the extent desired can be achieved. A strip of, for example, is well suited Polyvinyl chloride, which is only partially printed with one color on one side.

In the drawing, for example, is one of the possible embodiments of the grip strip according to the invention shown as a plan view. Next to a colored zone 1 extends a narrower, colorless cone 2 up to the edge of the grip strip.
