Abstract

Prior art album pages in which a transparent film is applied to a solid substrate, e.g. cardboard, are of inadequate bookbinding and optical quality. To make the album page of the invention, a transparent film (2) is bonded to one side of a substrate (3) at the upper and lower transverse edges by an adhesive seam (4; 5) and transversely by one or more additional adhesive seams (6), if required, to form a plurality of insertion pockets (1). The description also includes a device for applying an edging strip having a self-adhesive coating. Such album pages are bound together to make photograph, coin or other albums, visiting card sleeves and similar collective holders or arranged so that they can be fitted in ring-binders. The edging strip provides a particularly high optical quality and easy handling.

Description

ALBUM LEAF

description

The invention relates to an album sheet provided with at least one insert pocket, which consists of a base made of solid material and a transparent film connected to the base, and an inner longitudinal edge which can be fixed in an album, an outer longitudinal edge which runs parallel thereto, and has an upper and a lower transverse edge.

Such album sheets are bound to photo albums, coin albums or other albums, business card sleeves and similar collectibles or provided with stitching holes for recording in ring binders. The sheets are made of cardboard or a similar suitable material. The insert pockets are made of a transparent film.

From DE-OS 23 13 146 a pocket album sheet is known. According to this suggestion, the pockets are to be formed by passing folded strips of transparent film through slots made in the box, and then wrapping them around an edge of the box. Fastening strips are attached to the longitudinal edges of the sheet, with the aid of which the transparent strips are adhesively attached to the cardboard. The attachment strips are passed over rollers before being applied and thereby folded and then cut off in the length of the album sheet.

The solution has the disadvantage that complicated devices are required to handle the film strips. Outside— only pockets that can be loaded from the top of the sheet can be formed in this way.

From DE-GM 94 04 489 a further solution for forming insert pockets on album sheets is known. According to this, the transparent film has the shape of an envelope open on one side, into which the carrier material is inserted. In order to fix the film, the carrier material has holes through which both sides of the film sleeve are connected, preferably welded, to one another. The pockets should be open towards the binding edge of the album sheet.

The solution has the disadvantage that here, too, there is a technologically complicated process involved in inserting the cardboard sheets into the film envelope. On the other hand, as in the case described above, it is not possible to process the carton on a rolling basis, but only to process the individual carton sheets in cycles.

Further disadvantages are that, firstly, the optical quality of the album sheets due to the always visible connection holes in the carton and secondly the bookbinding quality due to the film covering the outer edges leaves something to be desired.

The invention has for its object to provide an album sheet that consists of cardboard or a similar solid support material which is connected to a transparent film in such a way that there are insert pockets which can be loaded from the center of the album. The album page should be technologically easy to manufacture, enable good bookbinding further processing and meet high visual requirements. A particularly suitable technology is to be specified for the production.

The object is achieved according to the invention in the case of an album sheet of the type mentioned at the outset in that the transparent film on at least one side of the base has this on upper and lower transverse edge and on the outer longitudinal edge with an adhesive seam and possibly to form several insert pockets in the transverse direction with one or more additional adhesive seams.

Cardboard is preferably used as the material for the base.

A plastic film, preferably a polyolefin film, can be used as the material for the transparent film.

The width of the transparent film is less than the width of the base. This is necessary once in order to create a binding edge of the album sheet. On the other hand, the width of the transparent film can be kept in such a way that a bar remains on the inside of the album sheet, which is used to label and design the album.

In order to conveniently load the groupage, e.g. Photos to enable lifting of the edge of the transparent film can be provided in a preferred manner that the adhesive seams at the upper and lower transverse edges start from the outer longitudinal edge and their length is less than the width of the film.

Additionally or alternatively, it can preferably be provided that the additional adhesive seams start from the outer longitudinal edge and their length is less than that of the adhesive seams located on the transverse edges.

According to a preferred embodiment of the invention, the adhesive seam on the outer longitudinal edge can be realized with the aid of an additional binding tape which is glued on all sides and is wrapped around the longitudinal edge.

At least one insert pocket is preferably formed on both sides of the base. The adhesive seams on the edges of the cardboard sheet preferably start directly on the sheet edge. At the edges of the album sheet, it is therefore not possible to leave the film behind. This makes it impossible to remove the film accidentally. In addition, a high optical quality of the album sheet is achieved.

The album sheet thus formed has very clean and uniform edges. When bound, an album made with these album sheets has a high optical quality both in the open and in the closed state. This applies in particular to an album sheet that has been provided with a binding tape on its longitudinal edge.

A method according to the invention for applying a binding tape provided on one side with a self-adhesive layer to form an album sheet consists of the following steps:

The binding tape is pulled off a supply roll, is guided via reversing centering and guide rolls under the edge of a running continuous cardboard web forming the base, which was previously glued on one or both sides with a film by means of adhesive seams running transversely to its transport direction, and closed part of its width glued on one side to the edge of the cardboard / film web. Thereupon, by means of a molded part which rests on the edge of the cardboard / film web, the edge of the binding tape projecting beyond the cardboard / film web is rotated by 180 'to the other side of the cardboard / film web and also with this side of the Cardboard / foil sheet glued. Finally, the cardboard / film web is cut into individual album sheets.

The binding tape is preferably drawn off from a supply roll by being carried along by the cardboard / film web. Neither the supply roll nor the rolls over which the binding tape is guided thus have a drive. The binding tape is large on the supply roll Length coiled spirally.

A device according to the invention is used to carry out the method, in which a pressure table loaded with a force parallel to the plane of the cardboard / film web and in the direction of the cardboard / film web can be moved linearly on rails arranged transversely to the transport direction of the cardboard / film web is guided, which carries a molded part for folding over the binding tape coming from a pull-off and feeding device and a guide roller for the binding tape, the molded part being positioned between a first and a second pressure roller, which are firmly connected to a machine frame and each act on the edge of the cardboard / film web led over the pressure table.

The pressure rollers are advantageously carried by a base table which is adjustably attached to the rails.

The cardboard / film web runs directly over the pressure table. It is passed between the pressure table and the pressure rollers and takes the pressure table with it when there are small lateral web movements over the molded part. For this purpose, the force exerted on the pressure table is applied, for example, by a tension weight which is articulated on the pressure table via a rope and a rope pulley. Additionally or alternatively, the pressure table can be resiliently supported in both directions with respect to the machine frame.

The molded part forms a slot together with the pressure table, which has a decreasing width in the transport direction of the cardboard / film web and is designed so that the edge of the binding tape projecting over the cardboard / film web initially protrudes 180 ° around the edge of the Cardboard / film web is put around. In connection with the floating storage of the molded part, this has the advantage over known solutions in which the tape is folded into a U-shape by means of nozzles or rollers before application, that the binding tape is always full at the edge without forming cavities of the album sheet and the folding is always strictly in the middle or in the intended area of the binding tape.

The pulling and feeding device for the binding tape is preferably designed such that it is constructed from a first deflection roller, which lies directly on the supply roller with its own weight, and from a second deflection roller, which acts on the first deflection roller with its own weight, both deflection rollers are guided so that they can move vertically in a slot-shaped guide and that the binding tape is first guided around the underside of the first deflecting roller, between the two deflecting rollers and around the second deflecting roller.

Since the adhesive force of the binding tape is to be overcome, it is appropriate for the first deflection roller to have a smooth surface and the second deflection roller to have a corrugated or corded surface.

The supply roll is a large roll on which the binding tape is coiled over a long length in a spiral. The pass band must therefore be passed over a centering roller after passing through the deflection rollers.

The invention will be explained in more detail below with reference to exemplary embodiments. In the associated drawings show:

10 - FIG. 14 the individual steps in the application of the binding tape to the edge of the album sheet.

The insert pockets 1 of the album sheet shown in FIG. 1 serve, for example, to take one photo at a time. The transparent film 2 is fastened to the cardboard sheet 3 by adhesive seams 4 on the upper and lower transverse edges and by an adhesive seam 5 on the outer longitudinal edge. To form two insertion pockets 1 an additional adhesive joint 6 is provided in the transverse direction ^¬. The photos are inserted from the middle of the album. The glued seam 6 is shorter than the glued seams 4 and therefore does not extend across the entire width of the film 3. In this way, a convenient lifting of the film edge is made possible and insertion of the photos into the insertion pockets 1 is made easier.

The width of the transparent film 2 is such that a labeling strip 7 is formed towards the inner edge of the album sheet.

Expediently, insertion pockets 1 are arranged on both sides of the album sheet, a label strip 7 remaining free towards the center of the album.

The adhesive seams 4 and 5 start directly at the edge of the album sheet 3. This prevents the film from touching the edges of the album page, which could result in the film being pulled off unintentionally.

2 shows a variant of the album sheet according to the invention, in which not only the length of the central adhesive seam 6, but also the length of the adhesive seams 4 at the upper and lower transverse edge of the album sheet is kept smaller than the width of the film 2 on the edges of the album sheet allows the edge of the film to be raised, thus further reducing the risk of the film 2 coming off the adhesive seams 4 when photos are inserted.

A particularly preferred embodiment in terms of optics and manageability results if the adhesive seam 5 is realized on the outer longitudinal edge by a binding tape which is placed around the longitudinal edge of the album sheet.

Fig. 3 shows a cardboard / film web 8 before separation into album sheets, which is provided with such a binding tape 9. An endless cardboard web is already connected to a film 2 via the adhesive seams 4 and 6. The carton / film web 8 is separated after application. gene of the binding tape 9. The cut runs in the middle through the adhesive seam 4, so that these places later form the upper and lower transverse edge of the album sheets. The arrow indicates the direction of transport of the cardboard / film web 8.

Fig. 4 shows a pulling and feeding device for the binding tape 9. The binding tape 9 is located on a rotatably mounted supply roll 10. On the side facing the supply roll 10, the z. B. made of plastic (PVC, polyester, polypropylene) edging tape provided with a self-adhesive layer 11.

The puller for the binding tape 9 consists of two deflecting rollers 12, 13 of the same width as the supply roll. They are mounted in smooth-running ball bearings 14 and guided in vertically arranged slots 15 of a guide bar 16, so that they constantly rest on one another and on the supply roll 10 with their own weight. The first deflection roller 12 is designed with a smooth surface, the second deflection roller 13 with a corrugated surface. The binding tape 9, starting at the point of contact of the first deflecting roller 12 on the supply roller 10, is guided around the first deflecting roller 12 in order to then be guided between the two deflecting rollers 12, 13 and around the second deflecting roller 13. This arrangement of the guide rollers ensures that the binding tape 9 is always pulled off the supply roll 10 at the same take-off angle. The constant pull-off angle on the one hand and the constant loading of the binding tape 9 by the weight of the deflecting rollers 12, 13 on the one hand lead to a constant pulling force in the binding tape 9 which is independent of the pull-off speed, on the other hand they prevent the supply roll 10 from running on when the belt speed or belt stop decreases .

After passing the deflecting rollers 12, 13, the binding tape 9, here initially via a guide roller 17, is by means of a centering roller 18 and guided over at least one further guide roller 19 to the edge of the cardboard / film web 8, not shown in the drawing.

Fig. 5 shows the pulling and feeding device again in a perspective view.

The further process sequence is shown in FIG. 6. The binding tape 9 guided under the cardboard / film web 8 is first placed half on the edge of the cardboard / film web 8 and pressed against it. The second half of the binding tape 9 now projects with its open adhesive layer 11 over the edge of the cardboard / film web 8. Subsequently, this überste _h edge of the binding tape 9 is folded by means of a mold part 20 to ₁ 80 "on the top of the cardboard / plastic belt 8 and bonded there with the film and the board edge.

The device for this purpose consists of a base table 21 and a transverse to the cardboard / Fol ien-web 8 movably guided pressing table 22. The pressing table 22 carries the mold part 20 for moving the binding tape 9 and a guide roller 23 on the _P age at which the binding tape 9 and the cardboard / film web _{8 are} fed. The position of the guide roller 23 is easily adjustable by means of a thread in relation to the cardboard / film web 8.

Are to _b eiden sides of the mold part 20 in the direction of Ban _d course of pressure rollers 24, 25 the first of _t he bottom arranged the cardboard / plastic belt 8, and after folding of the binding tape 9 and the upper side of the cardboard / plastic belt with the edge binding 9 connect. The pinch rollers 24, 25 _d sin fixedly mounted in the base table 21st

Since a slight lateral deflection of the cardboard / film web 8 cannot be avoided, on the other hand, the binding tape _{9 should} firstly lie against the edge of the cardboard / film web without forming cavities, and secondly the buckling band of the binding tape 9 in the present embodiment. game should run in the middle, so as to glue the binding tape on both sides of the cardboard / film web in a constant width, the pressure table 22 is acted upon by springs 26 and / or a weight with a force that the pressure table 22 and thus that Molding 20 always presses against the edge of the cardboard / film web 8.

When the cardboard / film web 8 deflects sideways in the direction of the molded part 20, the pressure table 22 including the molded part 20 and guide roller 23 is taken along. When moving sideways in the opposite direction, the pressure table 22 follows the movement due to its pressure force.

The molded part 20 comprises the edge of the cardboard / film web 8 and forms a u-shaped slot with the pressure table 22, this slot being shaped in such a way that the part of the binding tape 9 projecting over the cardboard / film web is folded over in a helical manner.

Fig. 7 shows the device in section along the line AC and makes the tables arranged one above the other clear. The base table 21 is movably mounted for adjustment, but is fixed during operation by a locking device, not shown here. The pressure table 22 is mounted so that it can move easily relative to the base table 21 and is subjected to a pressure force in the direction of the edge of the cardboard / film web 8, so that the molded part 20 always lies against the edge of the cardboard / film web.

8 and 9 show the molded part 20 in an enlarged view. Half of the binding tape 9 already applied to the underside of the cardboard / film web 8 runs in at the arc-shaped grooved leading edge 27 of the molded part 20 and is bent upwards in this area so that it is at an angle of 90 ° to the cardboard / film -Bahn 8 arrives in the transfer area 28. The laying area 28 forms together with the pressure table 22 on which the molded part 20th is fixed, by its wedge-shaped projection 29 a U-shaped slot, in the narrowing in the transport direction of the binding tape 9 is bent around the edge of the cardboard / film web.

10 - 14 show the steps taking place again in detail 1.

In step 1, the binding tape 9 is brought under the edge of the cardboard / film web 8 by means of the guide roller 23. in the

Step 2 is done by the pressure roller 24, the binding of the binding tape 9 to the underside of the cardboard / film web

8. At the same time, the edge of the binding tape 9 protruding beyond the cardboard / film web 8 runs into the leading edge 27 of the molded part 20. In step 3, the binding tape 9 has the

Area of the leading edge 27 passes and now runs into the

Transfer area 28 in which in step 4 the transfer to the

Edge of the cardboard / film web 8 is done. The final step is finally the pressing of the binding tape 9 onto the top of the cardboard / film web 8 by means of the pressure roller

25th

Finally, the cardboard / film web 8 only has to be cut into individual album sheets.
