EP2604439A1 - Manufacturing method for a booklet and booklet - Google Patents

Abstract

The method involves providing a booklet that comprises an over-size cover sheet (10) and a set of sheets (20), where the sheets are arranged top of another to form a stack. A glued binding (30) or a folded and glued binding is formed to bind the stack of sheets. The cover sheet is upwardly lifted from the sheets such that the cover sheet is positioned in an upright position at an angle of about 90 degree. The sheets are cut, and the cover sheet is folded back. The cover sheet is cut using a laser beam such that an outer contour of the cover sheet projects beyond the sheets. The cover sheet and the sheets are formed as printed paper sheets. An independent claim is also included for a booklet.

Description

The present invention relates to a booklet with an oversized cover sheet and a manufacturing method for such a booklet with an oversized cover sheet.

Booklets, i. small booklets with some leaves, provide a way to make a limited amount of information in print accessible to a user. Such a booklet usually covers a few to several tens of pages.

Usually, the pages are sheets of paper, which are usually printed on both sides. The individual sheets are joined together after printing and bound to one side. In the simplest case, the binding can be a joining by means of simple staples. For more sophisticated booklets, however, a glued or glued binding is usually preferred.

Finally, the leaves of the booklet at the outer edges are cut together to the desired format. Due to the limited number of pages and the resulting relatively low material thickness of the entire booklet can be used here on known cutting or punching.

Such a booklet can for example be enclosed with a product as a small information booklet or operating manual. In special applications, it is advantageous if the booklet is attached to the associated product. For example, such a booklet can be adhered to the product by means of an adhesive.

However, when gluing a booklet to a product as described above, there is a possibility that the individual pages of the booklet may be off the product. This would give an ugly appearance. Furthermore There is a risk that the booklet could be damaged very quickly or torn off the product when leaving individual pages.

In order to counteract the leaving of individual booklet pages, there are various efforts to also glue the top side of the booklet, so the cover sheet, with the corresponding product. For this purpose, however, it is necessary that the cover sheet of the booklet protrudes beyond the remaining sides at least at one point. Only then can the protruding area be glued directly to the product to prevent it from sticking out of the booklet pages.

However, as described above, if all pages of the booklet are cut to a common size during manufacture, the cover sheet initially has no area which would allow the product to be glued to the cover sheet. Therefore, it is necessary to enlarge the cover sheet at the desired location by additional process steps again.

For example, an additional layer of material may be applied to the cover sheet which is larger in size at the desired location than the underlying pages of the booklet. However, the cover sheet would consist of at least two different material systems and thus have a significantly greater thickness. In addition, the applied to the booklet laminate would have to be applied very precisely, which is associated with a correspondingly high production costs.

Alternatively, it would also be conceivable first to cut all the sheets of the booklet individually to the desired format and to choose a larger dimension for the cover sheet from the outset. Only after all leaves have been cut to size, they are joined together in a suitable binding process. However, this requires a very precise assembly and binding of the individual sheets with a correspondingly high process cost. Nevertheless, in As a rule, it can not be guaranteed that the user will be able to perceive certain tolerances of the individually assembled pages.

It is therefore the object of the present invention to provide an alternative, easy-to-implement manufacturing method for a booklet with an oversized cover sheet.

This object is achieved by a manufacturing method for producing a booklet with a cover sheet, comprising the following steps: providing a booklet with a cover sheet and at least one further sheet; Lifting the cover sheet from the at least one further sheet; then pruning the at least one further sheet; then fold back the cover sheet; and then trimming the topsheet so that its outer contour overhangs the at least one other sheet.

Furthermore, the object is achieved by a booklet with an oversized cover sheet and a plurality of further sheets, which was produced in the above-mentioned manufacturing process.

It is a particular approach of the present invention to first assemble all pages of a booklet together and connect them together by a suitable method and only then to crop the cover sheet and the remaining pages to different sizes. For this purpose, the cover sheet is first folded away from the remaining pages. Then all pages except the cover sheet are trimmed to a common length. In a separate step, the cover sheet is then trimmed separately to the desired shape.

By setting up the cover sheet can be achieved despite previous binding of all pages in a surprisingly simple and efficient way an oversized cover sheet, which is for the desired booklets and their application and processing of advantage.

Preferably, the cover sheet is trimmed so that the outer contour of the cover sheet is at least partially larger than the outer contour of the at least one further sheet or the plurality of further sheets after trimming. The cover sheet thus protrudes beyond the underlying sheet (s). As a result, on the one hand, the leaves of the booklet lying below the cover sheet are protected and, on the other hand, the projection of the cover sheet serves as a grip for opening the booklet.

In a preferred embodiment of the manufacturing process, in the step of setting the topsheet, the topsheet is set at an angle of about 90 degrees. With a cover sheet set up in this way, the remaining pages of the booklet can easily be trimmed without damaging the cover sheet itself.

In a special embodiment, the trimming of the outer contour of the cover sheet is done with a laser beam. The decision with a laser beam, also called "laser punching", is a suitable method to cut out the cover sheet in almost any outer contour. Thus, the greatest possible flexibility in terms of the shape of the cover sheet is achieved.

Preferably, in the step of providing the booklet, a raw booklet is provided with a plurality of contiguously juxtaposed booklets. Thus, multiple booklets can be made in one go in a single pass. Alternatively, in the step of providing the booklet, only a single booklet may be provided.

In a preferred embodiment, in the step of providing the booklet, a stack is provided with a plurality of stacked sheets. Particularly preferably, this embodiment also includes a step for binding the sheet stack.

The binding of the stack of sheets is particularly preferably carried out by means of adhesive bonding or seam-glue bonding. These binding methods have proven to be especially suitable for booklets.

Preferably, the method also includes a step of applying a top laminate to the topsheet. Such a top laminate reliably protects the underlying bucklet according to the invention. Particularly preferably, the upper laminate comprises an adhesive coating on the side facing the cover sheet, so that the entire structure can be comfortably applied to an object to be marked.

In a specific embodiment, the manufacturing method further comprises a step of applying a sub-laminate, wherein the sub-laminate is applied on the side facing away from the upper laminate side of the booklet. Thus, the booklet is protected from both sides by a top or bottom laminate.

A particular embodiment of the manufacturing method comprises a step of introducing a line of weakness into the top laminate. Thus, a part of the upper laminate can be separated quite easily and used separately as auxiliary or Belegetikett.

In the following the invention will be described with reference to the accompanying drawings. These are schematic drawings in the drawings. The proportions in the drawings do not necessarily coincide with the practical reality, but are greatly exaggerated in part for better representation. Show it:

• Figures 6a and 6b : a schematic representation of another alternative embodiment in cross section and plan view.

FIG. 1 shows a cross section through a booklet structure, which was created by means of a manufacturing method according to the invention. The booklet consists of several individual sheets 20. The individual sheets of the booklet may be one or more printed sheets of paper that have previously been folded in a suitably appropriate method to yield a multi-page booklet. Shown in FIG. 1 are four individual sheets 20 and cover sheet 10. In general, the number of sheets may be less or more, for example, up to 20 individual sheets plus cover sheet.

These individual leaves are in FIG. 1 connected on the left side in the region of the binding 30 by means of a suitable method. The binding 30 can be designed, for example, as an adhesive bond or produced in the seam-and-glue process.

The peculiarity of the booklet 1 in FIG. 1 consists now in that the cover sheet 10 projects at least partially on one side over the underlying pages 20 addition. In the illustrated example, it is on the right side shown the case in that cover sheet 10 protrudes right above the edge of the leaves 20 shown on the right.

The method according to the invention for producing such a booklet with reference to the figure will now be described below FIGS. 2a to 2f described.

As in FIG. 2a First, a stack of multiple sheets of the booklet is provided. As already described above, this may be, for example, one or more single or preferably double-sided printed paper sheets, which are suitably folded so that the individual pages come to lie one above the other in the correct sequence. Of course, it is also possible to put several individual sheets on top of each other and thus to get to a booklet with multiple pages.

In the next step, as in FIG. 2b shown, the leaves on one side firmly connected. This is usually done by means of a suitable binding method, which is known from the field of book binding. For example, the bond may be made as an adhesive bond or produced in a seam-and-glue process. Other binding methods that lead to the desired result are also possible. For the further explanations, a direction x is introduced which extends away from the binding in the direction of the opposite edge of the cover sheet 10 or of the further sheets 20 shown on the right.

In the in Figure 2c step shown, then the cover sheet 10 is then placed first upwards, so that it is approximately at right angles, so about a 90-degree angle upwards way. Basically, other angles are possible here. For example, the cover sheet could be folded by almost 180 ° to the rear way or less than 90 °, for example up to 45 °. In particular, the cover sheet is placed or lifted at an angle of 85 ° to 95 ° relative to the other sheets 20. However, it is essential in this step that the next step after cutting off the underlying pages by the cover sheet is not hindered.

After the cover sheet as in Figure 2c The manufacturing step shown above was folded away, then, as in Figure 2d represented, the underlying leaves 20 shortened in a joint step to the desired length in the direction x. Usually this step takes place by means of a sharp knife, a kind of fall ax, or even a suitable punching device.

In principle, this result could also be achieved in that the cover sheet 10 is only slightly lifted from the other sheets 20, so that a solid plate, such as a metal plate, between the cover sheet 10 and the cover sheet 10 closest further sheet 20 is pushed to ensure that the cover sheet 10 is not affected by the cutting process applied to the further sheets 20 and, conversely, that the cutting operation on the other sheets 20 is not hindered by the cover sheet 10 when the cutting or punching tool is brought from below to the booklet, ie the farthest from the cover sheet further sheet 20 is first contacted by the cutting or standing tool.

Subsequently, the cover sheet 10 can be folded back into its original starting position parallel to the other leaves 20, which is in FIG. 2e is shown.

In a further step, after the in FIG. 2e illustrated step as shown in FIG FIG. 2f the outer edge of the cover sheet 10 is shortened to the desired length in the direction x and shape. For example, cutting out by means of a laser beam is particularly suitable for this purpose. Such a laser beam can be guided almost arbitrarily by means of software and so also very individually cut complex contour shapes very accurately. However, at this step, it is important that the contour to be cut by the laser beam be outside of the underlying leaves 20. Otherwise, there is a risk that the underlying leaves 20 would be at least partially damaged by the energy of the laser beam. With regard to the shape can be provided to form a grip tab as described below, for example, grip tab 12 as in FIG. 6b shown and described. After completing this step, you will first receive a booklet in which, in the position shown, both the left and the right all the sheets have been shortened to the desired length.

In a further step, now also the remaining two known can be cut in a conventional manner by means of a knife, punch or the like to the appropriate length.

Basically, it is possible in the manner described above to crop each booklet separately and produce in this way each individual booklet. However, in order to enable a particularly efficient production process, it is also possible first of all to produce and provide paper stacks in which a plurality of booklets 1a to 1d are arranged next to one another, as is described, for example, in US Pat FIG. 3 is shown.

In the illustrated figure, for example, four booklets are arranged side by side, with any other number of adjacent booklets is possible. This means that printed sheets are created in which all contents are common to these four booklets. This will turn out for the step FIG. 2a first made a common stack of paper and then processed as described in the further course above. Such a paper stack, which comprises several individual booklets, is usually referred to as a raw booklet. The raw booklet in this example has an extent of four contiguous booklets. Each two immediately adjacent booklets are connected to one another and have a common, imaginary edge in the direction x running along, along which the booklets are later cut and separated. The adjacent booklets are arranged side by side in the direction y, with the direction y being perpendicular to the direction x. For example, each booklet contains the same print information, and the dimensions of each booklet in the raw booklet are the same.

After such Rohbooklet was prepared analogously to the manufacturing method described above with an oversized cover sheet, the individual booklets are then cut out by means of a suitable cutting or punching method and separated or singulated after the left outer contour of the common cover sheet of the raw booklet has been trimmed. Thus one obtains in a very efficient manner in a single process run a multiplicity of individual booklets.

Regardless of whether a booklet was produced directly as a single booklet, or whether the booklet was produced using a raw booklet with multiple uses, such booklets with an oversized cover sheet are particularly well suited as a self-adhesive solution for an application on a surface. As in FIG. 4 For example, an upper laminate 40 with an adhesive 41 can be applied over the cover sheet, which is applied to the cover sheet and projects at least partially.

With the protruding portions of the self-adhesive upper laminate 40 such a booklet can be particularly easily glued to a surface or an object. The oversized cover sheet of the booklet covers a portion of the self-adhesive laminate and thus protects the open side of the booklet from sticking together.

FIG. 5 shows an alternative embodiment of a composite comprising a booklet produced according to the invention with an oversized cover sheet. The booklet is first applied to a sub-laminate 50. The booklet is glued to the sub-laminate 50. The booklet can be adhesively bonded by means of an adhesive 51 either to the entire surface of the sub-laminate 50 or more preferably only in a small area as in FIG FIG. 5 shown.

To protect against damage and environmental influences, the booklet is provided with the sub-laminate 50 with an upper laminate 40, as has already been described above in the previous embodiment.

In order to be able to attach this structure of booklet, upper laminate 40 and lower laminate 50 as simply as possible to an object, this is under laminate 50 the side facing away from the booklet completely or partially provided with an adhesive 60. Adhesive adhesives are particularly suitable for this purpose.

In FIG. 6 a further embodiment of a structure with a booklet produced according to the invention is shown. In the previous embodiment, this construction comprises booklet, sub-laminate 50 and upper laminate 40. In contrast to the previous embodiment, this variant is supplemented on the right side shown by an additional area 100. On the lower side, this region 100 consists of an extension of the lower laminate 50. On the upper side, the upper laminate 40 is also correspondingly extended, wherein the upper laminate 40 is stamped along the edge 110, so that a weakening line is formed. Between upper laminate 40 and lower laminate 50 is an adhesive.

The oversized cover sheet 10 of the booklet produced according to the invention also protrudes partially into the additional region 100, so that upper laminate 40 and lower laminate 50 are not glued together in this region into which the oversized cover sheet 10 protrudes. The cover sheet 10 thus projects beyond the weakening line 110. In this area, therefore, a user can very easily reach into it and thus gets to grasp the upper laminate 40. Subsequently, the user can peel off the upper laminate 40 and glue it back in place due to the adhesive contained therein.

The top laminate thus removed from region 100 serves in this case as a type of printed label, which can be produced together with the booklet and applied to an article. At a later date, this leaflet may then be applied elsewhere for documentation purposes, for example.

The edge 11 of the cover sheet 10 of the booklet shown on the right is cut in such a way that it projects beyond the edge 21 of the further sheets 20 to the right and projects beyond the edge 21. In this case, the distance between the left and right edges 13 and 11 of the cover sheet 10 is greater than the comparable Distance between the left and right edges 13 and 21 of the other sheets 20. The right edge 11 of the cover sheet 10 is beyond the right edge 21 of the other sheets by a certain length, which length may depend on the application of the booklet. In practice, this length is at least 1 mm (millimeters), preferably about 2 - 4 mm. The length can be even longer if the booklet is to be applied to a round body, for example.

Furthermore in FIG. 6b the gripping tab 12 of the cover sheet 10 is shown, which is extended beyond the right edge 11 of the cover sheet 10 in the direction x. The grip tab comprises only a portion of the right edge of the topsheet 10 and is located at the upper longitudinal edge of the topsheet 10. The left edge 121 of the grip tab lies within the area of the area 100 and can be grasped by a person with fingers when the area 100 is removed is. In other words, the weakening line 110 extends over the gripping tab 12, while the weakening line in the area outside the gripping tab does not extend beyond the cover sheet 10.

In summary, the present invention relates to a manufacturing method for a booklet with an oversized cover sheet. For this purpose, all pages of the booklet are first joined together and connected. The cover sheet is then folded aside and the remaining sheets are trimmed to the desired size. Subsequently, the cover sheet is brought in a special process, preferably by means of a laser beam to the desired, over large format. The invention further includes a booklet in which, according to the above-mentioned manufacturing process, the cover sheet has been cut in other ways than the remaining sheet stack.
