BOUND BOOKLET IN PRSENTATIONSMAPPE AND PROCEDURES FOR MERGING

The invention concerns a presentation briefcase for the admission of a sheet pile, a bound booklet and a procedure for merging a sheet pile into a presentation briefcase with the characteristics of the generic terms of the independent patent claims.

For rapid binding of a sheet pile, i.e., a number of sheets between 1 and up to approximately 100 or more, which consist of paper, pasteboard or other printable material, with if possible little work and machine expenditure frequently for example loose-leaf binders are used. Here it concerns a briefcase with a covering containing a lower part and cover-hurries, which are connected at one of their Seitenkanten. The connection of documents in such a loose-leaf binder takes place frequently by means of a punching of the documents which can be brought in and one the punching appropriate photograph device within the loose-leaf binder. When using such a loose-leaf binder as presentation briefcase however the wertige general impression is disturbed by the remarkable photograph device. Besides the photograph device can loosen or open inadvertently, since it is also inadvertently easily operatable when each opening unfold the presentation briefcase. The photograph device usually rests against the inside of covering ILS, which when repeated up and pushing to manifestations of wear to cover-hurry lead can.

GB 2,253,374 describes a document briefcase, which exhibits a strip attached at a lower part of a briefcase, at which a sheet pile and cover-hurry one fastens and which after an attaching or clasping over the fastening parts one folds and these covered. The strip is not at the inside of the briefcase, but is from the outside visible. From the outside visible strip disturbs on the one hand the general impression, on the other hand exists by mounting lying outside the danger that the strip separates easily, from its folded position and the view of the booklet or clip means releases. A wertige casing of documents is not then ensured.

US 4.007.950 shows a booklet strip, which serves for the booklet attachment of a sheet pile and can around the attached edge of the sheet pile be folded. The strip exhibits break grooves and a section of the strip is at the back of the sheet pile to be glued to. A connection of the strip with a covering is not intended. In order to wrap a sheet pile, either covering and lower part would have to be inserted also into the booklet strip, or by means of further means of mounting a covering at the strip to be fixed. In both cases the means of mounting would be from the outside visible and disturb the general impression

US 4.793.758 shows a covering with a strip connected lying inside with the covering. This is provided with an adhesive, on which a sheet or a sheet pile can cling. The splicing tape exists only to a sheet of the sheet pile, whereby no solid connection between covering and sheet pile is producible, which would be suitable, loads, for example through sheets to hold conditions.

The task of the invention consists of avoiding the disadvantages of the acquaintance in particular a presentation briefcase presenting a bound booklet and a procedure for merging by which a pile of sheets is brought into an regulatory form with wertigem general impression and by which a solid connection between the sheet pile and the covering and if necessary between the sheets is at the same time ensured.

The task solved by a presentation briefcase from a covering with covering and lower part and at least one inside being because of the covering fastened booklet strip, whereby the booklet strip is at least so broad that place for an attaching, for a distance from attaching up to the page margin and the height of the sheet pile is given, and which in such a manner is folding booklet strip around the sheet pile that attaching is covered by the booklet strip in the umfalteten condition at least on a side of the sheet pile.

By an attaching connecting the sheets of the sheet pile and the booklet strip with one or more connecting and/or booklet means, staples, booklet thread, metal band, spiral volume or other one is e.g. understood.

A such attaching ensures for the fact that the sheets without large expenditure are to be connected firmly with the presentation briefcase and among themselves. The presentation briefcase is suitable from there manufacturing a solid and durable connection.

The presentation briefcase can exhibit a booklet strip, which is intended preferentially along the entire length of the presentation briefcase, or several booklet strips can be present along the length of the presentation briefcase, which ensure together that the sheet pile in the covering gets stop. In addition several booklet strips can be intended for the admission of several sheet piles in a covering.

The Umfaltung of the booklet strip contributes by the multi-layerness within the folding range to stabilization. Covering attaching by the booklet strip prevents that the booklet means rest against the inside of the covering and to these castings, scratch, manifestations of wear or other damages cause. If the booklet strip from obscure material is, in addition then by covering the booklet means a who tiger optical impression is favoured.

Preferentially that is at least booklet strips in such a manner folding that he covers at least the range of the booklet strip, which is intended for attaching the range of the sheet pile between attaching and page margin and the edge of the sheet pile on the length of the booklet strip. The edge of the sheet pile, at which attaching takes place, can be at least partly set in thus by the booklet strip. The impression of a high-quality connection, like it otherwise only from a comparatively complex procedure, results for example a book connection, is obtained, although the sheets are connected by an attaching only.

Due to the Umfaltung the free edge of the booklet strip and the edge of the sheet pile fit about together. Thus a simple accesibility with a tool results, like for example a temporary fastener.

Since the sheets and the booklet strip are connected with booklet means, which can be removed also again, a reversible, i.e. a solvable connection are present. Thus missing sides can be supplemented or redundant sheets be removed. This possibility does not exist during an adhesive bond, e.g. with hot adhesive.

In a preferential execution form the covering consists PP (polypropylene) of a first material, in particular, and that at least booklet strips of a second material, in particular PPP (Polyphenylen), which softer and/or more flexible than the first material is, in such a manner that the booklet strip on its width without tool several times break, and/or is folding.

In the following is described, what in the available case by softer, and/or more flexibly is to be understood. While it is favourable for the covering, if it possesses a certain rigidity, by which the sheet pile is protected in particular against breaks, should the booklet strip on itself and around an edge of the sheet pile be folding, to which it consists of a material suitable for it. In order to ensure the folding and/or break barness of the detention strip, this material must be sufficiently flexibly and/or softly, thus less hard than that the covering.

The flexibility, which has to exhibit the material, refers primarily to the foldingness, the stretching or compressibility of the material is less substantial.

For attaching of few or thin sheets the components of the presentation briefcase can be manufactured for example of paper of different strength, for instance the covering from firm pasteboard and the booklet strip of paper.

Depending upon desired firmness a large number of materials is usable, among them different plastics or also textile materials.

With the selection of the Materialen from the elastomers softness and/or pliancy with parameters can be described, how the bending strength, which lies e.g. for PP within the range of 30-40 MPa, the modulus of elasticity, which lies e.g. for PP within the range of 1300-1600 MPa, the notched-bar impact-strength, for PP with 23 C within the range of 4-10 kJ/m2, or the hardness, for PP e.g. the Rockwell hardness (D785) amounts to about 98, or about shore D70.

For the booklet strip it is important that it exhibits on the one hand a sufficient firmness for the admission of attaching and for carrying the sheet pile. On the other hand it must be flexible enough, in order to be conductible over its entire length along the sheet pile on itself fold backable and around the edge of the pile around. But the material should a certain tenacity exhibit and may not be not so brittle that it tears or breaks during strong bending load.

The covering usually cannot be broken in the range of the covering back, if it is for example einstückig manufactured, it however in small distances several times strongly is folded, like it with the booklet strip the case is harder and/or less flexible and can from there than these be.

PPP (Polyphenylen) is an example of a material, which combines firmness and Flesibilität particularly well with one another.

Both PP and PPP can be made available in any color selection, so that large organization variety is given.

In an execution form according to invention the booklet strip exhibits holes for the admission of booklet means. These can be set with accordingly holes existing in the sheet pile to coincide and taken up booklet means, which serve a solvable connection.

Preferred as booklet means staples are used. In this case no preparation of the booklet strip is necessary.

After a Umfaltung of the booklet strip the booklet means are covered by this and are not visible.

In a favourable execution of the invention the covering exhibits at least two pre-defined crease lines, which define a covering back.

At a crease line the covering can be folded easy in a certain direction. The covering receives thereby a certain form, in which by the distance of the crease lines a width of the covering back is given. A back certain width is favourable if the presentation briefcase is intended for the admission of a sheet pile with a Stapelhöhe, which does not exceed the covering width.

Presentation briefcases with backs can be stacked also with merged contents well. The back can be printed on or be provided with a sticker, so that a marking of the presentation briefcase is also readable, if the presentation briefcase stands on one of its edges.

Favourable way is fastened that at least booklet strips in a crease line. If the adjustment of the booklet strip, in particular by a sewing or a welding, runs along a line, which coincides with the crease line, then the attachment of the booklet strip takes place in a preferential folding line of the covering, which facilitates both a merging of the sheet pile and for the Umblättern.

Alternatively that can be fixed at least booklet strips in a distance from a crease line, outside of a section between this and a further crease line, which defines a covering back.

In a preferential execution form that exhibits at least booklet strips a range, with which he rests against the inside of the lower part of the covering. The booklet strip can cover then additionally a range on the back of the sheet pile.

In this case attaching on both sides of the sheet pile can be covered by the booklet strip. The edge of the sheet pile is set in by that at least one booklet strip at least on its length.

That at least one booklet strip can be along a line parallel to the crease lines to the covering fastened, preferentially exists however a laminar connection, as for example the range at least of the booklet strip, which covers a range at the back of the sheet pile, is fixed at the covering.

Preferably that possesses at least booklet strips a range, which is glue toable on the back of the sheet pile. While attaching already ensures that the booklet strip and the sheet pile are not against each other movable in the range of attaching, ensures sticking for the fact that the folding of the booklet strip cannot be cancelled any longer and so that the verge of the sheet pile is fixed.

The possibility for the gluing is preferentially through already at the booklet strip attached adhesive intended, e.g. by a self adhesive strip, which is covered by a protective plastic film before the gluing or which becomes sticking by dampening.

Preferred that exhibits at least booklet strips at least a pre-defined crease line, which separates the ranges for attaching and the distance to the edge of the sheet pile. When merging thereby the break line of the booklet strip is given to cover at which the booklet strip on itself back-folded, in order attaching. The given crease line facilitates the positioning and a merging of the sheet pile.

In a favourable execution form that exhibits at least booklet strips at least one crease line, which separates the ranges for the distance to the edge of the sheet pile and the range for covering the height of the sheet pile. The crease line is intended, where the booklet strip at the edge of the sheet pile lies close and ensures for the fact that booklet strips and sheet piles fit together and form no break bulge. In addition the given crease line facilitates a merging.

In a preferential execution form that is festgenäht at least booklet strips at the covering, with which covering welds, at the covering glued to and/or at the covering firmly attached.

The task is solved further by a bound booklet, which of a presentation briefcase with a covering, at least one inside being because of the covering fastened booklet strip, in particular of one like presentation covering, and a sheet pile, descriptive above, which consist are attached at that at least one booklet strip, whereby the booklet strip is so folded that it covers the range of attaching and the edge of the sheet pile.

Bound booklets according to invention can be very simply manufactured and offered a durable and optically fastidious connection.

Staples are intended favourable way as means for attaching. These are usually very narrow, and need toward perpendicularly to the attaching edge only minimum place. Attaching takes place thus practically along a line, which saves place and which leafing facilitates.

In an alternative execution form at least one metal band is intended as means for attaching, which is led by a punching in that at least one booklet strip and the sheet pile. In such a manner a solvable attachment can be achieved in a simple manner.

In addition the task is solved by a procedure for merging a sheet pile lying into a presentation briefcase with a covering and at least a one inside fastened booklet strips, in particular in one like presentation briefcase descriptive above, which exhibits the following process steps:

• Present the sheet pile on a covering inside, concisely to the booklet strip,
• Booklets of the sheet pile to that at least one booklet strip,
• Turn down the sheet pile on the other covering inside.

Preferred the covering before presenting the sheet piles is so far opened unfold that the exteriors of the covering lie one on the other. The booklet strip points then from the covering away and can be achieved well by a temporary fastener.

Back-folded when turning the sheet pile down the booklet strip on the one hand on itself, on the other hand puts it around de Rand of the sheet pile. It covers attaching.

Preferred inserting the sheet pile takes place in such a way that this lies first with the front on the booklet strip, which is pushed booklet gorges by the booklet strip and the sheet pile and which are bent staples on the back of the sheet pile. The sheet pile is then turned down on the back, whereby the booklet strip covers attaching on the front.

If the booklet strip is long enough, it can be resumed also still on the back of the sheet pile and be covered there visible attaching.
