Abstract

The cut-out section for forming the cover's (40) base consists of paperboard or cardboard. The outer surface (46) of the base material is coated with a stuck-on covering paper. The inner surface (45) has a stuck-on piece of paper or sheeting (55) as mirror. Before the paper or sheeting piece is applied to the base, the end parts (51) of the covering paper protruding beyond the cover are folded onto the inner surface of the cover and then the paper of sheeting piece is applied. An embossing calender (80) with two rollers (81,82) mechanically fixes the coating paper and paper or sheeting to the base.

Description

The invention relates to a method for manufacturing of blankets for file folders, using a Ceiling manufacturing device with a number of Calenders, with the blankets made from a beam Form of a blank from a solid material, like cardboard or cardboard, especially with uneven ones Surfaces or material-related surface structures, consists, the carrier on its outer wall surface with a reference paper, especially one Cloud marble paper or other suitable Material laminated using an adhesive is and using on its inner wall surface an adhesive with a laminated paper or Foil cut is provided as a mirror, wherein before embossing the paper or foil blank on the beam that protrude beyond the blanket Edge sections of the reference paper to the Folded inside wall surface of the blank, whereupon the paper or foil cut is then applied becomes. The invention further relates to a File folders from a blanket of cardboard or Cardboard, which is covered on its outer wall surface with a reference paper, like cloud marble paper or with one other suitable reference material and on it Inner wall surface covered with paper or plastic film is, with the formation of the file spine between the two formed lid parts two parallel and at a distance from each other transversely to the longitudinal direction of the cover blank running joint or Folding grooves are formed on the side of the back part limit the folder.

Conventional file folders consist of a blank blank made of cardboard or cardboard on the outside with a reference paper, like cloud marble paper, and on the inside with paper or plastic film is covered. By two transverse to the longitudinal direction of the cover cut running joint or rebate grooves the lid parts of the folder are formed, between which the spine lies. On the inner wall surface one of the two lid parts of the folder a line-up mechanism is arranged.

The reference materials are made using a Adhesive glued onto the blanket, first applying the outer reference paper becomes. Its edge sections are on the inner wall surface of the blanket folded, whereupon then the inner reference paper is laminated on, that the folded edge sections of the outer reference paper to be covered with. The lamination the cover materials are made on the blanket using folder cover or book cover machines, the are equipped with press rollers.

After laminating the cover materials onto the Blankets made of cardboard or cardboard are often shown sections of bubbles in the cover material, the insufficient liability of the reference documents is due to the fact that that the carrier material often depends on the material a surface structure, e.g. in the form of Grooving or the like has, which has the consequence that the Spread adhesive mass before the lamination process only on the raised sections of the carrier material comes to rest, so that no sufficient Gluing and liability of the cover materials on the Carrier is reached. The non-glued sections the reference papers then stand out in sections, which leads to this blistering. The use of larger amounts of glue, however, leads to a Cost increase and also the glue during the pressing process of the reference papers pressed out the blanket in the side area. In addition, the edge bonds in particular are often difficult and produce inadequate results to lead. Also the use of coating compounds, around smooth support surfaces for application Creating the reference papers leads to an increase the manufacturing costs for the file folders. Also the production of folders with reference materials, which consist of plastic film is often included Difficulties connected, since often none sufficient gluing of the cover material to the Material, such as cardboard or cardboard, of the blanket is reached, so that here too a section Blistering and wave formation in the cover materials may occur. These section-by-section replacements of the reference material from the carrier leads to unusable File folders. Such blistering due to incorrect bonding serious impact, especially on the Bonding of plastic films with cardboard cuts.

Especially when exposed to higher temperatures there is a risk that the plastic film, if not properly glued, expands and bubbles form that also no longer recede. Add to that faulty blankets additional Disposal costs entail what, in particular the case with the ceilings is made up of two different components, for example Plastic and cardboard, put together; these materials are no longer separable and must therefore be used as Hazardous waste.

Especially with regard to the cost saving effects are the known file folders Mass consumer goods because of their importance are subject to extreme price pressure, so that ultimately any way to reduce manufacturing costs reduce, high importance is attached.

The object of the invention is to provide an inexpensive largely scrap-free manufacturing process of files according to the one described at the beginning Way of creating with the addition of gluing of the reference paper or film on a support a solid material, such as cardboard or cardboard, a mechanical Anchoring the cover materials with the Carrier material is made by reducing the committee in the manufacture of the Cover the file folder especially for blankets that are made up of two different components, e.g. Plastic and cardboard, ecological Aspects arise in particular in that the otherwise inseparable materials for hazardous waste disposal must be fed.

This task is accomplished with a procedure with the in Features specified claim 1 solved.

Accordingly, the invention is that the Blanket cut for the folder forming support with the outside paper laminated on the outside and the paper or foil blank laminated on the inside for mechanical fastening of the cover materials on the carrier with a calender two rollers is guided, of which at least one Roll is designed as an embossing roller. After that is the manufacturing process for blankets for file folders followed by an embossing calender.

The invention then consists in anchoring of reference material with the carrier material by embossing for the production of file folders.

By adding an additional embossing calender following the manufacture of the ceilings for file folders there is a consolidation and anchoring the reference materials with the material, like cardboard or cardboard, of the blanket cut, from which the folder is made. The outer cover material, which on the blanket is laminated, consists of paper, in particular Cloud marble paper, or another suitable material, whereby embossed or unembossed Reference material can be used, whereas the inner reference material that the so-called "Mirror" forms, from paper, plastic film, one plastic-coated paper or from other suitable materials can exist. Also in this case the cover material can be made smooth or be embossed.

The savings potential is essential, because what As for the cloud marble folder, it becomes common a cloud marble paper used that already on the part of the paper manufacturer in a separate Work process is shaped and thus also by the Procurement side is significantly more expensive than one unembossed cover material. Since the file folder or Ceiling production on later downstream Embossed calenders the entire blanket is embossed, can also embossed material according to the invention be used. By embossing the complete Ultimately, blankets are not just the cover material shaped, but also due to the corresponding Embossed printing of the blankets, i.e. the cardboard core, provided with a structure (formation of beads). This formation of beads inside the cardboard core leads to use cardboard of low thickness can be without the flatness of the ceiling or the dimensional stability of the finished file folder is impaired becomes.

By applying an embossing to the Cover materials coated cardboard supports or cardboard there is a high and additional solidification, especially in the high demands exposed edge areas of the lid blank, namely insofar as that on the Folded inner wall surface of the blank Edge sections of the outer cover material, together with the edge sections of the inner covering these Cutting with the material of the blanket solidified and anchored by the applied embossing being, the embossing down into the material the carrier is made of cardboard or cardboard. Thereby is an increased solidification of the edge areas of the Cover materials on the material of the blank reached. A reference material is thus anchored with the carrier material Embossing in the production of file folders.

It is therefore the use of non-embossed cover materials possible that when going through the Blanket cut through the embossing calender at the same time with the anchorage with the material of the Ceiling cut receives an embossing. With the used Only the upper roller can emboss calender be designed as an embossing roller; there is also Possibility to use only the lower roller as an embossing roller to train. In addition, both rollers of the Embossing calenders can be designed as embossing rollers.

The one used to make the file folder cover outer cover material can already be embossed be provided. Also the cover material for the mirror can be embossed or unembossed. In the Cases in which unstamped, i.e. a smooth Surface materials with reference will get this when going through the blanket through the embossing calender. In in those cases where those already shaped Reference materials will be received, they receive after the blanket has passed through the Embossing calender an additional embossing, at the same time the mechanical anchoring of the cover materials with the material of the carrier made of cardboard or Cardboard is reached.

The use of the Method according to the invention in cardboard supports and cardboard and also with bad papers Quality and with material-related surface structure shown. Missing adhesive sections of the cover materials be on the carrier by the Embossed anchor replaced. This thus reached enhanced adhesive effect plays a very significant Role in the much more difficult to glue Plastic films according to the invention also used as reference material for the cardboard blanks can be, especially in the games and areas where the outer cover material is turned inside, because here the Restoring forces of the film are particularly effective. This creates a full-surface attachment and system of the reference materials on the material of the Ceiling cut achieved.

The embossing calender used and the one thus achieved Embossing is such that it is also in the material of the Reaches and intervenes for the blanket cut, so that mechanical anchoring is achieved becomes. There is also an additional stiffening of the entire blanket, so that an improved Dimensional stability is obtained.

In addition, that by the inventive method Adhesives saved for the lamination process which lowers folder manufacturing costs can be.

The invention further relates to a folder that is produced by the method according to claim 1, and from a blanket of cardboard or cardboard, the one on its outer wall surface with a reference paper, like cloud marble paper, or another suitable one Cover material, and on its inner wall surface with Paper or plastic film is laminated, whereby for Formation of the file spine between two cover parts two parallel and spaced apart from each other Gelek or Folding grooves are formed, the side Limit the back of the folder. This File folder shows a blanket from a blank Cardboard or cardboard on which by means of an adhesive laminated reference paper and / or the paper or paper laminated by means of an adhesive Plastic film cutting for mechanical strengthening and anchoring with the material of the Ceiling cut with an embossing or with a additional embossing when using surface textured Reference papers or surface textured Paper or plastic film for the inner wall surface of the blanket, by means of one Provide calenders with at least one embossing roller is, whereby also for the external covering material Plastic film can be used.

The invention further relates to a use a blanket of cardboard or cardboard with laminated on both sides and by means of one Embossed calender solidified and with the material of the blanket mechanically connected or anchored reference papers or plastic films for Production of files with two cover parts, a back part formed between the cover parts, two formed between these and the cover parts Articulated or rabbet grooves and one on the inside arranged on one of the two cover parts Lever mechanism.

Advantageous embodiments of the invention are Subject of the subclaims. This is how the invention looks Process the use of an embossing calender before, one roller or both Rolling with one over the entire roll surface extending stamping structure are provided. For Formation of a folder cover with two folder cover parts and with one between the two folder cover parts lying back part with different finely tuned surface structures an embossing calender is used, the one roller or whose two rollers have a rotating, smooth surface Section of the width of the trainee Folder back part with missing embossing structure and two, on either side of this section with the missing embossed structure have an embossed structure so that a blank cover for a file folder is obtained at which the cover materials with the cardboard support or cardboard in the area of the lid parts to be trained of the folder with an additional embossing to establish the mechanical connection between the reference materials and the carrier is provided. File folders of high quality are thus obtained. Their manufacture is significant Cost savings connected.

To form a folder cover with two folder cover parts and with one between the two Folder cover parts with different back sections coordinated surface structures, is according to another embodiment used an embossing calender, one of which Roller or its two rollers three side by side have lying circumferential sections, of which the middle section is one of the width of the folder back part has the appropriate width, and the lying on both sides of the middle section Sections correspond to the widths of the folder cover parts, the parts corresponding to the folder cover Roll sections with a coarse stamping structure and the middle roller section with a fine embossed structure.

Back and lid parts are in one piece via joint or Folding grooves 30, 30 'connected to each other. In the back part 12 is a reinforced grip hole 13 educated. On the inner wall surface 11a of the rear A parting device 20 is arranged in the cover part 11, attached to the rear cover part 11 is.

This aligning device 20 is a lever mechanism with lockable, the file to be filed, with perforations provided document receiving brackets 21, 21, each bracket 21, 22 a two-part Form with fixed stirrup legs 21a, 22a and pivotable by means of the tilting mechanism Bow legs 21b, 22b, the fixed Bow legs 21a, 22a and the pivotable Bow legs 21b, 22b together with the tilt mechanism are arranged on a base plate 25, which in turn is attached to the rear cover part 11 is.

The line-up device 20 is a two- or multi-ring rocker arm mechanism or as a two- or multi-ring tear mechanism trained, with multi-ring mechanisms, e.g. from eighteen or twenty-three Rings exist, can be used. Depending on The arrangement of the folder 100 is the line-up device 20 on the inner wall surface 11a of the rear cover part 11 or on the inner wall surface of the back part 12 attached. Back and lid parts 10,11,12 of the folder 100 consist of a blanket 40 made of cardboard or cardboard (Fig. 8). This blanket 40 of cardboard or cardboard is on the outside with a reference paper 50, e.g. a cloud marble paper, and on the inside with paper or a plastic film 55 laminated.

There are two in the front cover part 10 of the folder 100 Slots 15a, 15b to expand the capacity provided, in which the bracket 21, 22 of the Engage the lever mechanism of the aligning device 20 (Fig. 1 to 3). Over the bottom edges of the two Slots 15a, 15b each have a raster cam 15a ', 15b 'above, towards the slot Surface formed as an increasing sliding surface is to create a detachable connection between the lever mechanism and to reach the front cover part 10, which prevents the two cover parts 10, 11 automatically set up sideways.

The two joint or fold grooves 30, 30 ', the between the back part 12 and the two back parts 10, 11 run, are due to material deformation, e.g. trained by pressure. By this material deformation during the formation of the joint or fold grooves 30, 30 'arise on the Inside the folder bead-like reinforcements, whereas groove-shaped grooves on the outside are trained.

The blank that forms the ceiling of file folder 100 made of cardboard, cardboard or another suitable Material is on its outer wall surface 46 provided with the reference paper 50. Instead of Reference paper 50 may also use other reference materials are used, including those with or without Embossing. Cloud marble paper is preferred used. This reference paper 50 is in itself known manner on the blanket 40 and namely laminated onto the outer wall surface 46 thereof. Across from the dimensions of the blanket 40 is dimension the reference paper 50 so that the 40 protruding edge sections over the blanket 51 of the reference paper 50 on the inner wall surface 45 of the blanket folded and be connected to the blanket 40. On these inner wall surfaces 45 of the blank blank 40 becomes a paper blank or foil blank 55 laminated on the folded edge sections 51 of the reference paper 50 also covers (FIGS. 4 and 8).

Fig. 4 shows schematically the course for the production a ceiling of a file folder 100 with the individual process stages A to G. in stage A from a blanket 40 of cardboard or cardboard, it doesn't matter whether the blanket is cut 40 lying in the longitudinal or transverse direction through the individual manufacturing and processing stages is passed through. This blanket 40 has the required dimensions for the Production of file folder 100 on. In stage B the reference paper 50 is placed on the blanket 40 laminated by means of a folder or Book cover machine 60 with the two press rollers 61, 62, after laying on the reference paper 50 an adhesive application on the blanket 40 is done. The dimensions of the reference paper 50 are larger than the dimensions of blanket 40, so that protruding edge sections 51 can be obtained (level C). After this Laminating the reference paper 50 onto the outer wall surface of blanket 40 are the protruding ones Edge portions 51 of the reference paper in Direction of arrow X on the inner wall surface of the blank 40 folded (level C). The one so prepared Blanket blanket 40 is shown in level D. In stage E is then on the inner wall surface of the Ceiling blank a blank 55 made of paper or Laminated with foil or another suitable material, after applying a glue. Around Applying the blank 55 becomes the prepared one Blanket 40 turned according to level D, what by the arrow X1 is indicated.

However, the blank 40 turns not required if other feeders for the blank 55 to a blanket 40 are used. Laminating the blank 55 made of paper or film of a calender 70 with the rollers 71 and 72. Die Rolls 61, 62 and 71, 72 of the two calenders 60, 70 are designed as smooth rollers.

After the exit from the calender 70 is the Blanket cut 40 on both sides with cover material 50, 55 provided (level F). The one so prepared Blanket blank 50 then passes through another Calender 80, which is designed as an embossing calender and the rollers are designated 81 and 82. Should the ceiling cut with the laminated cover materials subjected to embossing on both sides then the two rollers 81, 82 of the Calender 80 formed as embossing rollers, the The surface structure of the two rollers is then formed in this way is that the embossing down into the material of blanket 40 takes place. But should only be embossed on one side, then is the corresponding roller 81 or 82 of the calender 80 designed as an embossing roller. The end product is then obtained in level G. Here is the blanket cut with its two laminated cover materials embossed on both sides. The reference papers and / or cover foils are by means of embossing with the material of the blank firmly connected and anchored, whereby by the Embossing both cover materials with a surface structure are provided. With the used Embossing calender 80 is a roller made of embossing roller and heated, while the counter roll as smooth roller is formed so that an embossing is achieved with raised patterns, this Embossing right into the base material of the blank 40 extends. Also both rollers 81, 82 can be designed as heatable embossing rollers be.

The blanket received in level G for the file folder is then with the joint or fold grooves 30, 30 ' Mistake. Trained on the inner wall surface of the rear The part of the cover then becomes the line-up device 20 applied. The training then takes place the grip hole 13 and the slots 15a, 15b.

Fig. 8 shows an enlarged vertical section Section one for manufacturing of the folder according to the previous procedure Blanket made using the embossing calender embossments obtained are indicated at 90. These embossments 90 extend from the reference materials into the material from which the Beam or blanket cut exists.

Should the blanket 40 with the laminated Cover materials 50, 55 on one or both sides over the entire surface then be one of the two Rolls 81, 82 or both rolls 81, 82 of the calender 80 with one over the entire roll surface extending stamping structure. This imprint then extends over the back part of the folder to be trained later. The The direction of feed of the cover part to the calender 80 takes place in the direction of the arrow Y (FIG. 5).

On the other hand, should be on the carrier of the blank 40 laminated cover materials 50, 55 only in the area of the lid parts to be trained 10, 11 of the folder can be embossed, then one of the reels or both reels 81, 82 of the calender 80 so designed that this Rolls for embossing a surface structure only in those areas that have the areas capture the cover parts 10, 11 later of folder 100 form. The middle section 80b, which is the width of the future back part 12 is then with a smooth surface provided, while the two adjoining laterally Sections 80a of the rolls of the calender 80 to form an embossing with corresponding Surface structures are provided (Fig. 6).

On the other hand, should the back part 12 of the file folder 100 with a fine embossing, then they are Rolls 81 and / or 82 of the embossing calender 80 with one middle section 40b provided for training embossed surface structure has, whereas the two side sections 80a also for training, e.g. one larger embossing with the corresponding surface structures are provided, which extend over the circumference of the roller extend so that then when passing on both sides or only on one side with cover materials 50 and / or 55 coated supports of the Blanket blank 40 provided with embossing in this way are that e.g. the coinage for the area of Cover parts 10, 11 have a coarser structure, than the surface structure in the area of the back part 13.

The invention is not limited to that in the Drawing and embodiment described above. The manufacturing process for the ceiling of the File folder can also be prescribed Procedures differ and are performed, however it is essential that an embossing calender follows is with which the on the carrier of the blanket blank laminated cover materials by means of applied Not embossed with the material of the carrier only glued but also additionally anchored are. The material used for the ceiling cut for the File folder and its strength is chosen so that after the Embossing the material does not deform.
