Abstract

The folded or foldable sheet (1) has a sheet of paper, which has an adhesive area (3) on its inner side on a folding part (1.1), coated with a pressure-sensitive adhesive, and has an anti adhesive area (4) or only little adhesive to the pressure-sensitive adhesive on another folding part (1.2). The anti adhesive area is equal to the adhesive area and completely covers these, if the sheet of paper is folded along a folding line (2), and the adhesive area and the non-adhesive arealies on each other.

Description

The invention is in the field of printing technology and the further processing of printed products and relates to a folded or foldable sheet according to the preamble of the independent claim. The sheet is folded along an effective fold line and / or foldable along a potential fold line. It has an inner side and an outer side and two Faltteile, which are separated by the fold line. The sheet is particularly suitable for attachment to a printed product or to another, flat object.

In the non-prepublished International Patent Application no. PCT / CH2006 / 000543 a method is described, is added to the multi-page, folded or bound printed products, which thus have a specific folding or Rükkenkante, each one supplement. The supplement may also be attached to the printed product. The printed products are for example newspapers, magazines or brochures and the supplement is folded along a folding line. It is fed in the folded state, then opened and placed immediately after opening on the printed product so that it rests on the front or back of the printed product or on its folding or back edge and aligned its fold line on the folding or back edge of the printed product is. For attachment of the deposited on the folding or back edge of the printed product Supplement is proposed to apply before the discontinuation of the supplement on the front or back of the printed product in the area of the folding or back edge or on the folding or back edge itself an adhesive and optionally press the insert after settling to the adhesive. It is also proposed to attach the insert by stapling the printed product.

Of course, it would also be possible to apply an adhesive on the inside of the insert in the process briefly described above for attaching the insert to the printed product. An activatable adhesive would be easy to include in the supplement, but would have to be activated in an additional step (heat treatment, irradiation, etc.). A pressure-sensitive adhesive could be introduced only immediately before placing in the already opened supplement, which would not be easy.

The object of the invention is to provide a folded sheet, which is suitable, for example, as a side dish in the method described briefly above and is ready for attachment to the front or back of the printed product or at its folding or back edge so finished that nothing must be presented on the printed product for the attachment and that the supplement still needs to be slightly pressed at least for their attachment to the printed product after placement in order to be attached in a satisfactory manner to the printed product. It should also be possible to stack appropriately equipped sheets. The sheet according to the invention should not only be suitable for the method briefly described at the outset for attaching an insert to a folded or bound printed product in the manner mentioned, but should also be used for other methods in which a folded sheet is applied to one printed product or to another be attached flat object, be applicable.

This object is achieved by the folded or foldable sheet, as defined in the patent claims.

In the present specification, the term "bow" is used very generally. The term "bow" is to be understood not only a once or more than once folded or foldable bow but also a multi-layered, violent structure, which effectively consists of more than one sheet.

The folded or foldable sheet according to the invention has an inner side and an outer side and is folded along an effective fold line and / or foldable along a potential fold line. He has two folding parts separated by the fold line. On the inside of the first folding part, an adhesive area is arranged, in which the sheet is coated with a pressure-sensitive adhesive. This means that the adhesive area of the first folding part is permanently tacky without activation and adheres to it by contacting and, if necessary, lightly pressing on another surface. In order that the adhesive area does not adhere to the inside of the second folding part of the sheet when the sheet is folded, a non-stick area is arranged on the inside of the second folding part such that the two areas are substantially in contact with each other when the sheet is folded. That is, the adhesive area and the non-stick area are arranged substantially mirror-symmetrically relative to the fold line. The non-stick area can be the same size as the gluing area, but is advantageously somewhat larger and completely covers the gluing area when the two areas lie in a folded arc. The non-stick area is equipped in such a way that the pressure-sensitive adhesive of the adhesive area can not adhere to it or only adhere to it in such a way that the two areas can be separated from each other by using only a very small peeling force.

The sheet is in the non-stick area of the non-stick material (e.g., silicone) or coated with such material. Material combinations of pressure-sensitive adhesive and non-stick material are known per se to the person skilled in the art. The non-stick area can also be a recess in the second folding part of the sheet.

The sheet according to the invention can be fastened in a very simple manner to a printed product or to another, flat object in at least partially open state, namely simply by being pressed against the printed product or the object in the area of the adhesive area. However, the bow according to the invention can also be opened without problems by the two folding parts, which do not adhere to one another or only to a very small extent thanks to the pairing of adhesive area / non-stick area, be moved away from one another. Furthermore, it is also possible to stack sheets according to the invention in a folded state without the sheets adhering to one another. If the non-stick area is formed as a recess, it is unavoidable for non-stick stacking to adapt the dimensions of the non-stick area and thus of the gluing area to the thickness and flexibility of the sheet material. As will be shown, it is therefore advantageous in the case of thin and / or very flexible sheet material to provide a plurality of smaller non-stick areas and corresponding adhesive areas instead of a single, relatively large non-stick area.

The sheet according to the invention consists for example of paper, of a paper-like material or of a plastic. He is a simple bow or can also consist of several layers, so it can also be folded several times or formed as a booklet, with adhesive area and non-stick area are arranged on the inside, for example, the middle sheet of the booklet. The sheet according to the invention may or may not be printed, although it is quite possible that the adhesive area (under the pressure-sensitive adhesive) and, if it is not formed as a recess, also the non-stick area (under or even a corresponding coating of the sheet material). The sheet according to the invention is designed, for example, as a supplement which is to be applied and fixed on the folded or back edge of a printed product (eg newspaper, magazine or booklet). He serves in this embodiment, especially promotional purposes. The sheet according to the invention may also be a partial sheet of a multi-page printed product to be produced by collecting or a cover sheet for a printed product or for another flat object (eg plastic container for CD or other flat product).

Exemplary embodiments of the inventive sheet will be described in detail with reference to the following figures. Showing:

Figures 1A and 1B

a first embodiment of the inventive sheet in unfolded and folded state;

FIGS. 2 and 3

two variants of a second embodiment of the inventive sheet in the folded state;

FIG. 4

a stack of folded sheets of the embodiment according to Figure 2 or 3 in section;

FIGS. 5 and 6

two further embodiments of the inventive sheet in unfolded state;

FIG. 7

a printed product with an inventive bow.

Figures 1A and 1B show a first exemplary embodiment of the inventive arc. The bow is in the unfolded state in FIG. 1A shown from its inside and in Figure 1B in folded or kinked state.

The sheet 1 has a fold line 2 (in the unfolded state: potential fold line, in the folded state effective fold line), which divides the sheet into two fold parts 1.1 and 1.2. If the two folding parts 1.1 and 1.2 as shown in the figure have transverse to the fold line 2 different dimensions, the sheet can be opened very easily.

The inside of the first folding part 1.1 is equipped with the adhesive area 3, the second folding part 1.2 with the non-stick area 4, which consists in this case of a not adhering to the pressure sensitive adhesive of the adhesive area 3 material or coated with such. Of course, the whole sheet may consist of the non-adhesive material. The non-stick area 4 is slightly larger than the gluing area and is arranged so that it is mirror-symmetrical relative to the gluing area 3 in such a way that it completely covers the gluing area 3 when the sheet 1 is folded along the fold line 2.

The sheet according to FIGS. 1A and 1B can be printed on both sides. In this case, the adhesive area 3 (under the transparent pressure-sensitive adhesive) and / or the non-stick area 4 (on a non-adhesive material or under a corresponding coating) can also be readily printed.

FIG. 2 shows a further exemplary embodiment of the sheet according to the invention in the folded state. Like elements are designated by like reference numerals as in FIGS. 1A and 1B. The non-stick area 4 is formed in this case as a recess in the second folding part 1.2.

FIG. 3 shows a further embodiment of the sheet according to the invention, in which a plurality of adhesive areas 3 and non-stick areas 4 are provided, wherein the non-stick areas 4 are in turn formed as recesses in the second folding part 1.2.

Figure 4 shows a section through a stack of sheets, as illustrated for example in Figures 2 and 3. It can be seen that, although the non-stick areas 4 are formed as recesses, the pressure sensitive adhesive of the adhesive areas 3 in the stack can not adhere to the outside of the first folding part 1.1 of an adjacent sheet, since the second folding part 1.2 of the sheet is therebetween. It can be seen from FIG. 4 that the size of the non-stick region 4 and thus also the size of the adhesive region 3 are adapted to the inherent rigidity or flexibility and thickness of the sheet material. For a very stiff sheet material, the areas can be almost any size regardless of the thickness of the sheet material, because the first folding part 1.1 of a sheet will not bend into the recess of the second folding part 1.2 of an adjacent sheet and thereby come into contact with the pressure sensitive adhesive. However, if the sheet material is flexible and, in particular, if it is thin and flexible, the first folding part of a sheet will have a tendency to bend into the recess of the second folding part 1.2 of the adjacent sheet and come in contact with the pressure sensitive adhesive, which only by correspondingly small dimensions of the non-stick area 4 can be avoided.

FIG. 5 shows, on a further embodiment of the sheet according to the invention, further aspects of the invention in order to show that the sheet according to the invention does not have to be rectangular, does not have to be folded perpendicularly to its edges and can also have several fold lines, whereby it folds around one sheet the fold lines (effective fold line) is folded and the other fold lines are formed as potential fold lines (scratched, grooved or perforated). That means with others In other words, the invention is not bound to any particular form of the sheet nor to any particular sheet material.

For example, the arc shown in Figure 5 has a square shape with rounded corners, has a plurality of parallel and spaced apart fold lines and these are diagonally aligned. The two non-stick areas 4 are dimensioned so that they cover the adhesive areas 3 in the folded state of the sheet, regardless of along which fold line the sheet is folded. Depending on the folding, one or the other of the fold lines is the effective fold line 2 and the others are potential fold lines 2 '.

In particular, if the non-stick area 4 is formed as a recess and the sheet 1 is printed, it is advisable to make adhesive area 3 and non-stick area 4 small and as close as possible to the fold line or to the fold lines.

Sheets with a plurality of parallel and spaced-apart fold lines are particularly suitable for placing on a relatively wide folding or Rükkenkante a printed product, because they can bend along all fold lines and thereby bend plygonartig around such an edge.

FIG. 6 shows a last exemplary embodiment of the sheet according to the invention. This has two parallel and spaced apart fold lines, where it is to be folded along fold line 2 (effective fold line) and the other fold line is a potential fold line 2 '. The adhesive area 3 is arranged between the two fold lines 2 and 2 'and the non-stick area 4 is arranged relative to the effective fold line 2 mirror-symmetrically to the adhesive area. If the sheet according to FIG. 6 is folded along both fold lines, it has a back surface whose Inside is sticky. This sheet is therefore particularly suitable for placement on a back edge of a print-bound example, or on a similarly designed edge of another flat object, wherein the width of this edge is approximately equal to the distance between the two fold lines 2 and 2 'of the sheet 1. Der Sheet according to FIG. 6 can be stored and fed in a very simple way along the folding edge 2. It can simply be opened and placed on a corresponding edge, to which it simply adapts itself by folding around the fold line 2 '. For attachment, the adhesive area only has to be pressed against the edge. The sheet according to FIG. 6 can be, for example, a cover sheet for a printed product.

FIG. 7 shows a printed product with a front side 11 and a rear side 12 and a back edge 13, along which, for example, an adhesive binding or stitching runs. An arch according to the invention, e.g. As shown in Fig. 6, is attached to the printed product such that its adhesive portion 3 rests against the back edge 13. The first folding part 1.1 and the second folding part 1.2 cover the front 11 and back 12 partially here; Covering the entire surfaces in the manner of an envelope is also possible. The printed product bears an imprint 15, e.g. the title, and the sheet 1 according to the invention may also carry a print 14, e.g. Advertising or additional information. The imprint 14 may also be located in the adhesive area 3.
