Description

The invention relates to an adhesive fastening for plate material made from a tongue made of paper or the like the like, which along a fold line dividing the tongue into two sections on itself turned over and provided with glue on the inside.

A known adhesive fastening for sheet material (DE-PS 9 33 943) is used essentially for fastening of drawing paper on drawing boards. In order to avoid drawing pins that have difficulties when drawing self-adhesive strips are used to attach them. To be able to achieve the goal is like this therefore the adhesive fastening as double-sided with self-adhesive, which does not completely cover the carrier Adhesive formed. To get such an adhesive strip despite the adhesive application on both sides to be able to wind into a roll of adhesive tape without the adhesive tape on both sides of the carrier stick together, the adhesive layers are on one side of the carrier opposite the Adhesive layers arranged offset on the other side of the carrier. The double-sided with self-adhesive «· Adhesive-coated adhesive tape can also be used as a cover for books and magazines or the like. Use. One uses adhesive strips on one side in the central area have an adhesive layer, while on the other hand they are offset in the edge area two layers of adhesive are provided. The adhesive layer in the central area is used to hold the Side edges of the sheets to be inserted in the area of the fold line. When turning over the adhesive strip along the Fold line in the central area, the external adhesive strips point outwards and serve as a connection with the outside adhesive layer of the next adhesive strip. So there is glue on glue to lie.

It is already known (BE-PS 6 43 767) the sticking together of adhesive strips during transport and storage by a perforated layer to prevent the adhesive partially covers, but gluing under pressure is permitted

The object of the invention is to provide an adhesive fastening for easy and quick connection or tacking of sheet material, such as loose sheets, that are reliable in function and handling This object is achieved by the invention specified in claim 1

Appropriate refinements are given in the subclaims.

It can first be seen that with regard to the adhesive areas on the adhesive fastening depending on their location or their distance from the fold line is proceeded. If necessary, a narrow adhesive area is provided in the area of the fold line, which extends on both sides of the fold line and can be used to first fix the sheet edge. In the Remaining areas of the partial sections of the adhesive fastening away from the fold line on both sides of the fold line Adhesive areas and areas with anti-adhesive coating are offset in such a way that when the two sections of the adhesive fastening on top of each other, never two adhesive areas in this remaining area come to rest on each other. In addition, one of the sections protrudes over the other. The for this required different shape or area of the subsections can for example by corresponding Cropping can be achieved.

The adhesive fastening is expediently stored in the folded state in which the two Sections are turned over to each other. By grasping the protruding section, If a loose sheet is to be inserted, separate the two slightly from one another, as they are at a distance from the fold line One adhesive area in each case comes to lie on an antique adhesive covering and only has a slight stapling effect here Has. The adhesive area, which may be present along the fold line, can also be easily opened. Now the loose sheet is inserted and the two sections are hit against the inserted one from the outside Sheet material. This is with its edge in the possibly existing adhesive areas along the Fold line and / or with its side surfaces through the adhesive areas in those remote from the fold line Remaining areas reliably held. In this way one obtains a and which satisfies the practical needs well In addition, easy-to-use adhesive fastening.

In principle, it is possible to produce the adhesive fastening from a single tongue, the adhesive areas and has areas with anti-adhesive coating. Is particularly easy to manufacture and easy to use but an adhesive fastening made of two tongues, the first of which is entirely with adhesive on the inside is coated, with a second tongue being placed on this adhesive layer of the first tongue, whose Outside has an anti-stick coating and has holes through which the adhesive on the first to nee in

Form of adhesive areas is exposed. The holes are arranged in such a way that when the partial sections are turned over on themselves, each adhesive area is applied An anti-adhesive coating section of the second tongue comes to rest. The adhesive areas can expediently along the fold line, which are turned over on themselves, in the same technique as in the second tongue formed holes are made. This creates when needed and appropriate Training a fixed attachment fold. Of course, several such adhesive fastenings can also be used lengthways of a sheet are attached laterally next to each other, whereby, for example, when using a lid a binding can arise.

Handling is made even easier if the outside of the adhesive fastening has an anti-adhesive coating It can also have a metal layer that deforms under pressure and then one in particular Forces intimate contact of the adhesive of the adhesive areas with the sheet material to be stapled

In this context, “adhesive” is to be understood as a material that becomes in contact with a surface firmly connects to this surface without being moistened, heated or otherwise must be treated.
