     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention concerns a coplanarly joined print carrier made from at least two laminar partial print carriers, wherein one of the partial print carriers has a paper layer. The invention also concerns a partial print carrier with a paper layer, as well as a method for making such a print carrier and partial print carrier. A print carrier or partial print carrier within the context of the present invention is understood to be a substrate, especially a sheet, web, or page-like substrate, which is printed and/or can be printed on one or both sides. The substrate can have a single or multiple-layer construction 
     2. Description of the Prior Art 
     Print carriers based on paper sheets are increasingly needed, which are improved by means of local affixed items, usually in conjunction with die-cutting, and which contain integrated cards or labels, for example. The affixed items generally involve laminates, which contain the plasticizing and adhesive layers required for the integrated cards or labels. As an example, reference may be made to WO 95/20493. 
     The affixed items cause local thickening of the printed carriers, which is not of any consequence for individual print-carrier sheets, but when placed in a stack, as it increases in height, it adds up and result in increasingly skewed stacking. 
     In order to avoid this skewed stacking, which prevents full loading of the magazines, various solutions have already been proposed: 
     One proposal according to DE 197 41 563 consisted of making a single print carrier with an integrated card, instead of local affixing, i.e., providing it with the layers needed for the integrated card over the entire surface. However, this solution could not be successful, due to the much larger quantity of costly material needed for this. Also, the print carriers in this embodiment are altogether quite rigid and heavy and can hardly be folded at all, due to the layers of film usually present. 
     A proposal according to WO 2005/100006 consisted of retaining partial affixing on part of the surface and preventing skewing of the sheets in the stack by means of increasing thickness deformations imprinted in the paper material. However, due to the high elasticity of paper, these deformations have shown themselves to be insufficiently stable over time. 
     A print carrier was proposed in WO 92/05036 in the form of a card laminate with a first card, made of paper, for example, and a second card, in which the second card is fastened at one segment of the first card incised under pressure and exhibits a surface which is coplanar with it, so that skewing cannot occur in the stack. However, it results from this that this proposal could not be successfully achieved because the impression in the paper material of the first card would break down over time, due to the high elasticity of paper, as was the case with the aforementioned deformations. 
     In WO 00/41895, a coplanarly joined print carrier made from at least two laminar partial print carriers, of the type mentioned at the beginning, was proposed, in which the partial print carriers are glued together at their contiguous edges with essentially no overlap. However, it was not possible to achieve a sufficient binding strength in practice, at least not at a reasonable cost. 
     SUMMARY OF THE INVENTION 
     The invention poses the problem of specifying a print carrier of the kind mentioned at the outset, in which both partial print carriers are robustly joined together coplanarly in a technically simple and systematically executed way and in which the partial print carrier comprised of the paper layer can simply consist of this paper layer and the other partial print carrier can consist, in particular, of a laminate suitable for integrated cards. 
     This problem is solved according to the invention by means of a print carrier with the features of patent claim  1 . The print carrier according to the invention is characterized by the fact that the thickness of the paper layer of one partial print carrier is therefore attenuated along one edge strip by removing a partial layer, that the other partial print carrier exhibits a lesser thickness along one edge strip than elsewhere, and that both partial print carriers are joined together along their two edge strips. 
     The two partial print carriers can be firmly joined together with their two edge strips, in particular by mutual overlap. In the area of overlap, a total thickness can be obtained in this way which is no greater than the thickness of the partial print carriers elsewhere. Alternatively, the two partial print carriers could also be joined together by their edge strips by bonding with at least one strip, in particular an adhesive strip, in which the thickness of the strip will be offset by the lesser thickness of the partial print carriers in the area of their edge strips, and likewise by means of at least one strip will in sum cause no increase in thickness besides, compared to the thickness of the individual partial print carriers. 
     According to a first preferred embodiment of the invention, the partial layer is removed from the paper layer by tearing it off. In this regard, the invention utilizes the knowledge that paper material can be split and that a strip with a partial layer of the paper material can, after making a suitable rip, be further torn off almost continuously at an extremely constant thickness. 
     Alternatively or in addition, the partial layer could be removed by an abrasion process, in particular by grinding or milling. 
     If the second print carrier is a multilayered card laminate with at least two layers that can be separated from each other, a strip can be removed from at least one layer of this laminate and thereby likewise obtaining a thickness reduction along an edge strip. 
     Preferably, the edge strip of the paper layer of one partial print carrier is delimited from the rest of the paper layer by a cut in the paper layer. The same holds true for the other partial print carrier, in particular if this is a laminate with at least two layers which can be peeled away from each other. 
     In a further preferred embodiment, the other partial print carrier is shorter in the direction of the edge strip than the partial print carrier containing the paper layer. This construction is then especially advantageous if the surfaces needed for an integrated card, for example, are less wide in the other partial print carrier, in particular it has to be only half as wide as the print carrier containing the paper layer and the other partial print carrier is moreover of an expensive laminate. 
     Both partial print carriers can be joined with each other by an adhesive strip, which is provided with a transponder. A transponder could also be contained in an adhesive strip, which is glued along a strip of a print carrier attenuated by removing a partial layer. 
     One object of the invention is a partial print carrier with a paper layer for making a print carrier according to the invention, in which the thickness of the paper layer is attenuated along an edge strip by removing a partial layer. Preferably, the partial layer of the paper layer is removed by tearing it off. Alternatively or in addition, the partial layer could be removed by an abrasion process, in particular by grinding or milling. 
     The partial print carrier can be provided with an adhesive layer covered by a peel-off covering layer at the edge strip of the paper layer. 
     Moreover, an object of the invention is a method for making a print carrier or a partial print carrier according to the invention, in which the partial layer is removed from the paper layer by tearing it off along the edge strip. 
     Preferably, the partial layer of the paper layer is torn off with an adhesive strip. Critical to the resultant thickness here of the partial layer are the tear conditions. Preferably, the adhesive strip is pulled off, along with the partial layer of the adhering paper layer, using a roller. In continuous production, with the paper web and the adhesive strip in the form of continuous webs, the two webs are passed across two rollers that wind against one another. Due to the tear conditions which are very uniform here, corresponding, rather, to a lifting off, a very uniform thickness can be attained for the partial layer and, thus, also for the remaining layer of the paper layer along the edge strip. Above all, the thickness of the partial layer can be influenced here by the choice of diameter for the roller(s). 
     Another object of the invention is a method for making a print carrier or a partial print carrier according to the invention, in which the partial layer of the paper layer is removed along the edge strip by abrasion, in particular by grinding and/or milling. 
     As a result, the edge strip of the paper layer exhibits a smooth edge facing the rest of the paper layer, it is delimited by a cut in the paper layer, before removing the partial layer. The depth of the cut should correspond here to roughly the desired thickness of the partial layer. 
     Provided that the second print carrier is a multilayered laminate, the edge strip on it can likewise be delimited from the rest of the laminate before peeling off at least one layer by means of a cut in the laminate. The depth of the cut should correspond to at least the desired thickness of the partial layer. 
     A glued join is preferred for connecting the two partial print carriers along their two edge strips, with the two edge strips overlapping, in which, also preferably, if necessary, an adhesive layer is transferred dry from one carrier to one of the two edge strips. This has an advantage over a wet application of the adhesive layer, in that the adhesive layer is immediately available for gluing both partial print carriers and does not have to be dried first. A hot glue could also be considered, or a connection using an already existing coating by pressing the two webs together. 
     Finally, the method of the invention is preferably a continuous method, in which the two partial print carriers are present as webs and are processed, preferably at the same time, for example, by running off a roller. In addition to their being joined together, the two partial print carriers could also undergo further processing steps in the same run, such as, for example, printing or die-cutting, and finally separation. 
     In a further method according to the invention, two outer and one middle partial print carriers are used for the essentially waste-free manufacture of a print carrier, with the other partial print carrier shorter in the direction of the edge strip than the partial print carrier containing the paper layer, in which both outer partial print carriers each contain a paper layer and each is attenuated in thickness along an edge strip by removing a partial layer and in which the middle partial print carrier exhibits a lesser thickness along two facing edge strips than the thickness elsewhere. The outer partial print carriers are each bonded along their edge strips to one of the edge strips of the middle partial print carrier. Then the partial print carriers so connected are passed by means of an edge strip alternately facing one another and in between the middle partial print carrier crossing a parting line separates into at least two of the print carriers.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1   g ) shows a print carrier A/B of two laminar partial print carriers A and B, joined coplanarly with mutual overlapping. The partial print carrier A consists of a single ply or layer  1  of paper. The partial print carrier B is a laminate with roughly corresponding thickness, made up of three layers  2 ,  3 , and  4 , in which layers  2  and  4  can likewise be a paper layer or a film layer and layer  3  is a so-called peelable adhesive layer, which allows the layer  2  to be separated from it and it thereby remains behind on layer  4 . 
     For the purpose of their coplanar joining, the partial print carriers A and B are each attenuated in thickness along an edge strip  5  or  6  by removing a strip-like partial layer  7  from the partial print carrier A and a strip-like layer  8  from partial print carrier B. To facilitate this and to obtain a neat boundary for the edge strips  5  and  6 , the partial print carriers A and B can be provided with cuts  9  and  10  beforehand.  FIGS. 1   a ) and  1   b ) show the two partial print carriers A and B in their original state, but already provided with such cuts  9  and  10 .  FIG. 1   c ) shows the strip-like partial layer  7  of paper layer  1  along the cut  9  of paper layer  1  and is thus represented as separated from partial print carrier A, whereby the separation is achieved by tearing it off, with fraying of the paper material.  FIG. 1   d ) shows the strip-like layer  8  along the cut  10  separated from partial print carrier B, whereby part of layer  2  is formed and is separated from the peelable adhesive layer  3 . Then, on at least one of the attenuated edge strips  5  and/or  6 , here edge strip  6  of partial print carrier B, an adhesive  11  is applied as a strip, as  FIG. 1   e ) shows. As represented in  FIG. 1   f ), the two partial print carriers A and B are finally glued together at their edge strips  5  and  6 , mutually overlapping so that they come to lie essentially coplanar, as  FIG. 1   g ) shows. With suitable attenuation of the two partial print carriers A and B, possibly allowing for the thickness of the glue  11 , the same thickness is obtained, at most, in their area of overlap  5 / 6  as the two partial print carriers each have, as this is preferred. The print carrier A/B, which is assembled from the two partial print carriers A and B, then likewise exhibits an essentially consonant thickness over its entire surface. 
       FIG. 2   a ) shows a device for making a print carrier A/B according to  FIG. 1  in a continuous process using partial print carriers A and B, which are present as continuous webs and are unwound from feed rollers  20  and  21 .  FIG. 2   b ) shows plan views of the webs A and B running through the device of  FIG. 2   a ).  FIG. 2   c ) represents a section through the finished print carrier A/B. 
     From the feed roller  20 , web A is taken to a first die-cut unit  1  with a die-cut cylinder  22  underneath and a opposing cylinder  23  on top, in which it runs onto the opposing cylinder  23  in the die-cut unit The die-cut cylinder  22  is provided with at least one rotating cutting edge to produce the cut  9  of  FIG. 1  as the web A runs through the gap between the two cylinders  22  and  23 . Ahead of this gap in the direction of rotation, a roller  24  rests against the die-cut cylinder  22 , whereby a first adhesive strip K 1 , with a supporting film layer and an adhesive layer, which is pulled off a roller  25 , is transferred onto the die-cut cylinder  22  with the adhesive layer pointing outward. At the same time, a cover for the adhesive layer on the roller  24 , such as one in the form of a silicone paper S 1 , is pulled off the adhesive strip K 1  on the roller  24  and passes to a roller  26 , onto which it is wound. The adhesive strip K 1  comes in contact with the web A in the gap between the two cylinders  22  and  23 , and there it is glued firmly to it under pressure. Subsequently, carrying along with it a partial layer of the paper layer of web A, as will be further explained below, it runs further around the die-cut cylinder  22  as far as a deflection roller  27 , by which it is carried away from the die-cut cylinder and fed to a wind-up roller at  28 . 
     The adhesive strip K 1  is so proportioned in width and so oriented relative to the web A and the cutting edge  22 . 1  making the cut  9  in it ( FIG. 3   a )) that it comes to lie between one of the side edges of web A and the cut  9 , and preferably the space between them is also essentially filled. In particular, it fits tightly against the cutting edge  22 . 1  on the die-cut cylinder  22 . 
     While now, since the adhesion of the adhesive layer of the adhesive strip K 1  to the paper material of web A is chosen to be greater than the internal strength of the paper material, it tears this up or frays it in the direction of travel on the aforesaid edge strips  5 , so that a partial layer of the paper layer corresponding to the partial layer  7  of  FIG. 1  remains stuck to the adhesive strip K 1  on the die-cut cylinder  22 , while web A besides runs further around the opposing cylinder  23 . The partial layer  7  torn off by the adhesive strip K 1  and stuck to it is wound up, together with the adhesive strip K 1 , onto the roller  28 . The specific tearing conditions can be kept exactly constant in the procedure described, so that an approximately constant tear depth results, with a correspondingly constant attenuation of web A along its edge strip  5 . 
     Therefore, three processes take place at nearly the same time in the gap between the two cylinders  22  and  23 : the production of the cut  9  for a straight boundary at the edge strip  5  being attenuated, the application of the adhesive strip K 1 , and the tearing off of the partial layer  7  with the adhesive strip K 1 . 
     Web A with its attenuated edge strip  5  is then passed around various deflection rollers, including a second die-cut unit II, as is described below. 
     The second die-cut unit II contains a die-cut cylinder  30  on top and an opposing cylinder  31  underneath. This second die-cut unit II receives the web B fed from the feed roller  21  such that it runs onto the opposing cylinder  31 . The die-cut cylinder  30 , like the die-cut cylinder  22 , is provided with at least one rotating cutting edge ( 30 . 1  in  FIG. 3   b )) to make the cut  10  of  FIG. 1  as web B runs through the gap between the cylinders  30  and  31 . Because of the cut  10 , the strip-like layer  8  of  FIG. 1   d ) is cut free and can then be pulled around the die-cut cylinder  30  besides from the rest of web B and can be wound up on a roller  32 . 
     Web B with its thus attenuated edge strip  6  is then passed to a station III, at which an adhesive corresponding to the adhesive  11  of  FIG. 1   e ) is applied in a strip to the attenuated edge strip  6 . The adhesive  11  is applied dry by means of a pair of rollers  33 ,  34 , using pressure, and is at the same time passed from a feed roller  35 , on which it is arranged between two covering layers of silicone paper S 2  and S 3 . One of these covering layers, S 2 , is, prior to applying the adhesive layer  11 , pulled off it by a roller  36  running against the roller  33  and is wound onto a roller  37 . The other covering layer, S 3 , is pulled off it by a roller  39  only after applying the adhesive  11  to web B and is wound onto a roller  38 . The adhesive  11  then lies exposed on the top side of web B at its edge strips  6 . In order for the adhesive  11  to be separated in the proper sequence from the covering layers S 2 , S 3 , its adhesion with respect to the covering layer S 2  must be clearly less than with respect to the covering layer S 3 . 
     At another station IV with two press rollers  40  and  41 , web A and web B are brought together and glued to each other with the adhesive  11 , under pressure, overlapping their two attenuated edge strips  5  and  6 , as is also evident from  FIG. 2   c ). It is important that the pressure be exerted by the rollers  40 ,  41  in the overlap area, for which a so-called final adjustment is provided there. It can be seen from  FIG. 2   a ) how web A passes around the press roller  40  and is joined to web B. In  FIG. 2   b ), it can be seen that the two webs A and B have been moved laterally relative to one other by means of the device, so that both their attenuated edge strips arrive at station IV with the press rollers  40  and  41  with precisely the desired mutual overlap and are pressed together. 
     As a result, a print carrier A/B has already been finished according to the present invention, albeit in the form of a continuous web, which is wound onto a roller  46  and could be made available for further continuous processing, for example at a print shop. But in practice, there is an increasing need for single sheets that can be handled by sheet printers. For that reason, a third die-cut unit III is also provided in the device of  FIG. 2   a ), with a die-cut cylinder  42  and an opposing cylinder  43 , in which there is at least one cutting edge on the die-cut cylinder  42  that is oriented transverse to the direction of travel of the web A/B, for cutting single sheets to length from the web A/B. Reference  44  depicts a device for picking up and stacking the single sheets and  45  a stack of sheets. The sheets can have typical formats such as A4 or letter size. 
       FIGS. 3   a ),  b ) and  c ) clarify the situation at the three die-cut cylinders  22 ,  30  and  42  in the die-cut units I, II and III, in which the individual figures each show a longitudinal section through the die-cut cylinder and in which the sectional planes are each chosen as indicated by dashed lines, as in  FIG. 2   a ). 
       FIG. 3   a ) shows the situation at die-cut cylinder  22  of the first die-cut unit I. The sectional plane is here chosen to be slightly slanted, so that it cuts the upper edge of the die-cut cylinder  22  shortly after the gap between it and the opposing cylinder  23 , which is represented only in  FIG. 2   a ). The cutting edge rotating at the die-cut cylinder  22  to produce the cut  9  in web A is indicated as  22 . 1  and is composed of a thin die-plate, which is held magnetically on the die-cut cylinder  22 . The die-cut cylinder  22  is moreover, like the other die-cut cylinders as well, incidentally constructed as a magnetic cylinder. The adhesive tape K 1 , as already described, passes to the die-cut cylinder  22  so that it fits tightly against the cutting edge  22 . 1 . In the gap between the die-cut cylinder  22  and the opposing cylinder  23 , the cutting edge  22 . 1  penetrates into web A. The adhesive strip K 1  is also glued here under high pressure to web A. At almost the same time, the tearing and separation of the partial layer  7  from web A begins in the gap, while the adhesive strip K 1  with the partial layer  7  adhering to it continues to run through some rotational angle on the die-cut cylinder  22 , while web A rotates around the opposing cylinder  23  and, past the gap, is removed from the adhesive strip K 1  and the partial layer  7 , as can be seen in  FIG. 3   a ). 
       FIG. 3   b ) shows the situation at the die-cut cylinder  30  of the second die-cut unit II. Once again, the sectional plane is here chosen to be slightly slanted, so that the lower edge of the die-cut cylinder  30  is cut by it soon after the gap between it and the opposing stacking the single sheets and 45 a stack of sheets. The sheets can have typical formats such as A4 or letter size. 
       FIGS. 3   a ),  b ) and  c ) clarify the situation at the three die-cut cylinders  22 ,  30  and  42  in the die-cut units I, II and III, in which the individual figures each show a longitudinal section through the die-cut cylinder and in which the sectional planes are each chosen as indicated by dashed lines, as in  FIG. 2   a ). 
       FIG. 3   a ) shows the situation at die-cut cylinder  22  of the first die-cut unit I. The sectional plane is here chosen to be slightly slanted, so that it cuts the upper edge of the die-cut cylinder  22  shortly after the gap between it and the opposing cylinder  23 , which is represented only in  FIG. 2   a ). The cutting edge rotating at the die-cut cylinder  22  to produce the cut  9  in web A is indicated as  22 . 1  and is composed of a thin die-plate, which is held magnetically on the die-cut cylinder  22 . The die-cut cylinder  22  is, moreover, like the other die-cut cylinders as well, incidentally constructed as a magnetic cylinder. The adhesive tape K 1 , as already described, passes to the die-cut cylinder  22  so that it fits tightly against the cutting edge  22 . 1 . In the gap between the die-cut cylinder  22  and the opposing cylinder  23 , the cutting edge  22 . 1  penetrates into web A. The adhesive strip K 1  is also glued here under high pressure to web A. At almost the same time, the tearing and separation of the partial layer  7  from web A begins in the gap, while the adhesive strip K 1  with the partial layer  7  adhering to it continues to run through some rotational angle on the die-cut cylinder  22 , while web A rotates around the opposing cylinder  23  and, past the gap, is removed from the adhesive strip K 1  and the partial layer  7 , as can be seen in  FIG. 3   a ). 
       FIG. 3   b ) shows the situation at the die-cut cylinder  30  of the second die-cut unit II. Once again, the sectional plane is here chosen to be slightly slanted, so that the lower edge of the die-cut cylinder  30  is cut by it soon after the gap between it and the opposing cylinder  31 , which is represented only on  FIG. 2   a ). The cutting edge rotating at the die-cut cylinder  30  to make the cut  10  in web B is indicated as  30 . 1  and is again composed of a thin die-plate, held magnetically on the die-cut cylinder  30 . The strip-like partial layer  8  of web B, cut free by means of the cut  10 , is pulled off web B, while it runs further on the die-cut cylinder  30  through some angle of rotational, during which web B leaves the gap between the die-cut cylinder  30  and the opposing cylinder in a straight line. 
     In the embodiment examples described so far, the edge strips  5  and  6  of the two partial print carriers A and B are each oriented straight and parallel to one another, both as to their outer edges as well as the cuts  9  and  10 . As a result, two hinge areas occur on the finished print carrier A/B, indicated as G 1  and G 2  in  FIG. 1   g ), along which both partial print carriers A and B can be rolled against one another with little resistance. For many applications, this may be insignificant or even advantageous, but for others it may in comparison be undesirable. In the latter case, the hinge effect can be avoided to a large extent by means of a reciprocal gear-tooth construction of the two partial print carriers along their edge strips  5  and  6  and a bend-resistant connection produced. It is sufficient for this for example, to construct the two edge strips  5  and  6  as reciprocally undulating in opposite directions, to be precise, in terms of their outer edges as well as the cuts  9  and  10 , as is represented in  FIG. 2   b ′), where the cuts are indicated as  9 ′ and  10 ′. What is more, the cutting edges on the die-cut cylinders  22  and  30  must be constructed as correspondingly undulating, as  FIGS. 3   a ′) and  3   b ′) show and where the corresponding cutting edges are indicated as  22 . 1 ′,  22 , 2 ′,  30 . 1 ′, and  30 . 2 ′. The cutting edges  22 . 2 ′ and  30 . 2 ′ are required here, in addition, to cut the outer edges of webs A and B in an undulating pattern, whereby cutting waste results. The two cutting edges  22 . 1 ′ and  22 . 2 ′ on the die-cut cylinder  22  can at the same time be used to advantageous to cut out, for example, with straight edges, from the adhesive strip K 1  fed from the roller  25 , an adhesive strip K 1 ′ exactly matching in wavy contour, whereby again, cutting waste will naturally result here, but it can be removed along with the covering S 1 . 
     The thickness of the partial layer  7  tom away from the paper layer of the partial print carrier A to attenuate its edge, and as a result the measure of this attenuation, depend on the quality of the paper used as well as, in part, on the rate of tearing, but above all on the angle of tear, whereby the thickness decreases as the tear angle becomes larger. The depth of the cut  9  plays practically no role in this connection. A sharp-edged separation of the partial layer  7  will occur even if the depth of the cut  9  is somewhat less than the thickness of the partial layer  7 . The adhesion of the adhesive strip K 1  used in the device of  FIG. 2   a ) to the paper surface plays no essential role in the thickness of the partial layer  7 , as long as this adhesion is just large enough. 
     In the device of  FIG. 2   a ), the tear angle is determined, on the one hand, by the diameter of the die-cut cylinder  22  and on the other hand by that of the opposing cylinder  23 . These diameters typically amount to 110-150 mm for the die-cut cylinder  22  and 60-140 mm for the opposing cylinder  23  and thus are relatively large, which yields a relatively small tear angle and a large thickness of the partial layer  7  torn off, which is usually favorable in practice. If, however, one wishes to reduce this thickness, the modified die-cut unit I′ can be used, for example, as represented in  FIG. 2   d ). With this, the web A and the adhesive strip K 1  with the attached partial layer  7  are separated from one another onto a pair of rollers  29  with distinctly smaller diameter, arranged behind the die-cut cylinder and opposing cylinder. 
     Due to the measures described above, the thickness of the partial layer  7  can be adjusted relatively precisely to the respective desired value, particularly in the 20-120 μm range where, for example, a thickness of 25 μm is suitable for paper with a density of 80 g/m 2  and a thickness of 50 μm is suitable for paper with a density of 120 g/m 2 . For paper with density greater than 140 g/m 2  and over 185 μm thick, the thickness of the partial layer  7  can be as much as 100 μm. 
     The laminate used in  FIGS. 1-3  for the partial print carrier B and the web B is specially suited to making integrated cards, in particular if the layer  2  is sufficiently thick, rigid, and thus self-supporting. The device of  FIG. 2   a ) also allows, based on, the die-cut units which there anyway, just such integrated cards to be produced, at least in the laminate of web B in layer  2  in the same run as the bonding of the two webs A and B. What is more, it is sufficient in principle to provide the die-cut plate in the die-cut cylinder  30  with an additional rotating cutting edge, as represented in  FIG. 3   b ) and  FIG. 3   b ′) and indicated as  30 . 3 , and with this to cut into web B on the side of the layer  2  down to the depth of the peelable adhesive layer  3 . The cards thus cut out along their perimeter from layer  2  are indicated by  12  in  FIG. 2   b ) and  FIG. 2   b ′) and the corresponding cut in layer  2  by  13  in  FIG. 3   b ) and  FIG. 3   b ′). The integrated cards  12  are held on web B and in the finished print carrier A/B by the peelable adhesive layer  3  on layer  4 , but they can also be detached from layer  4  by virtue of the separation properties of the peelable adhesive layer  3  and removed from the print carrier A/B. 
     On the die-cut cylinder  42  of the third die-cut unit III of the device of  FIG. 2   a ), a die-plate could be provided, as represented in  FIG. 3   c ), for example, with a rotating cutting edge  42 . 1 , whereby this cutting edge  42 . 1  could cut out individual print-carrier sheets from the web A/B, by producing a die-cut grid (rather than cutting the web to length and crosswise). Alternatively or also in addition, a rotating cutting edge  42 . 2  could be used to cut into layer  4  of web B. This would be of interest, for example, within the contours of integrated cards  12  produced in layer  2  of web B, as represented by a dashed line in  FIG. 2   b ) or  FIG. 2   b ′) and indicated by  14 , because a layer would thereby be produced that would accompany the integrated cards  12  at their removal from the print carrier, which could, for instance, be provided with a previously applied imprint 
     In the embodiment examples described above, the partial print carriers A and B were joined together coplanarly with a mutual overlap of their two attenuated edge strips  5  and  6 .  FIG. 4   a )- c ) shows basically how this might be possible without any mutual overlap of these edge strips, in contiguity, by using one strip  15  or two strips  15  and  16 , whereby the strip or strips each bridge the contiguous area The total thickness, consisting of the residual thickness of the two edge strips and the thickness of the strip or strips, shall further correspond roughly to the thickness of the two partial print carriers A and B. In particular, the strips  15  and  16  can be adhesive strips. 
     The partial print carriers A and B are not further specified as to their construction in  FIG. 4 . Actually, there could be a single paper layer in both of the partial print carriers. One or both partial print carriers could also be a multilayered laminate, such as, for example, that represented for partial print carrier B in  FIG. 1  and used to make integrated cards in  FIGS. 2 and 3 . 
     A plastic film, in particular in layer  2 , for example, made of polyester with a thickness in the range of 75-250 μm could be used in the multilayered laminate, as is represented for partial print carrier B in  FIG. 1  and is used to make integrated cards in  FIGS. 2 and 3 . The peelable adhesive layer could exhibit a thickness in the range of 3-10 μm, and the layer  4  could be a carrier layer with a thickness of 23-36 μm. In this case, there would result a total thickness for the partial print carrier B, and thus, preferably, also for the paper material of the partial print carrier A, between 101-296 μm. The paper material preferred to be used would be one having a large volume and low weight, i.e., a low density. 
     The two edge strips  5 ,  6  could, in particular for a bond with mutual overlap, exhibit a width between 3-12 mm, but preferably between 4-8 mm. 
     In  FIGS. 5-8 , further selected examples of the layer construction for the two partial print carriers A and B are clarified, on the one hand their bonding as facilitated according to the invention and on the other hand the manufacture of various integrated products, where the partial print carrier A in  FIGS. 5-7  again consists respectively of only a single paper layer, while the partial print carrier B is respectively a multilayered laminate. 
     In  FIG. 5 , partial print carrier B exhibits the following layered construction from top to bottom: a first film covering-layer  50 , a first adhesive layer  51 , a paper layer  52 , a second adhesive layer  53 , a second film covering layer  54 , a peelable adhesive layer  55 , and a carrier layer of paper or film  56 . Along one edge strip, a strip with the layers  50 - 54  is removed from the peel adhesive layer  55  and is glued together there with an attenuated edge strip of the partial print carrier A by means of an adhesive  57 , with overlap. Due to a rotating die-cut  58 , extending from the first film covering-layer  50  down to the peelable adhesive layer  55 , an integrated card  59  is cut free in the partial print carrier B, which, by virtue of the separation properties of the peelable adhesive layer  55 , can be removed and is shown as removed in  FIG. 5   b ). The card  59  exhibits, as is often the case with such cards today, a paper core  52  with plasticizing on both sides by means of the film covering-layers  50  and  54 . 
     In  FIG. 6 , the partial print carrier B exhibits, from top to bottom, a layer  60  consisting of paper, for example, an adhesive layer  61 , a silicone parting layer  62 , and a carrier layer  63  of paper or film. Along one edge strip, a strip with the layers  62  and  63  is removed from the adhesive layer  61  and glued there with overlap an attenuated edge strip of the partial print carrier A, using the adhesive of the adhesive layer  61 . Due to a rotating die-cut  64  in the layer  60 , an integrated self-adhesive label  65  reaching down to the parting layer  62  is cut flee in the partial print carrier B, which can be removed due to the separation properties of the parting layer  62 , and is represented as removed in  FIG. 6   b ). 
       FIG. 7  shows that a laminate with a wear layer  70 , corresponding in construction to the laminate of the partial print carrier B of  FIG. 6 , could also be used to make, for instance, a folded card  71  which is not sticky on the outside, which after folding together and gluing its parts  72  and  73 , exhibits more than twice the thickness of the layer  70 . The layer  70  here could advantageously be a relatively thick film layer. 
       FIG. 8  shows an embodiment in which the partial print carrier A is also a multilayered laminate and has, besides an upper paper layer  80 , an adhesive layer  81  and a carrier layer  82  of tear-resistant film. This construction has the special advantage that no extra adhesive strip is needed to tear off a partial layer of the paper layer  80  in order to attenuate it at the edge, because such is already there, due to the layers  81  and  82 . It is sufficient to provide the partial print carrier A with a cut, after which the partial layer of the paper layer  80  can be torn off immediately with the integrated adhesive strip. 
     The partial print carrier of  FIG. 8  exhibits the reverse sequence of layers to that of  FIG. 6  or  7  with the layers  83 - 86 , where layer  86  is a transparent film layer. To attenuate the margin of the partial print carrier B, a strip with the layers  83  and  84  is removed, in which layer  84  is a parting layer that can be readily detached from the adhesive layer  85 . The adhesive of this adhesive layer is immediately used to bond the two partial print carriers A and B, so that, again, no extra glue is needed. 
     From the construction described above, a flip card  90 , for example, can be produced, in which an imprint  91  previously applied to the paper layer  80  of the partial print carrier A is arranged, protected under a transparent film layer. For this, a first partial card  87  is cut free in the partial print carrier A by a first die-cutting, in which, however, it is still held in the partial print carrier A by means of individual webs in the carrier layer  82 . A second partial card  88  is cut free in the partial print carrier B by a second die-cutting, which is likewise still held in the partial print carrier B by means of individual webs in the layer  86 . To make the flip card, in a first step, the part indicated as  89 , containing the layers  83  and  84 , is removed from the partial print carrier B, whereby the underlying are an of the adhesive layer  85  is uncovered. In a second step, the partial print carrier B is folded around the bonding area on the partial print carrier A like a hinge, whereby the exposed adhesive layer  85  comes in contact with the surface of the partial card  87  provided with the aforesaid imprint  91  and can be glued to it. In a third step, the finished flip card  90  can be removed from the print carrier A/B by breaking the aforesaid webs. 
     Print carriers A/B according to the invention are ultimately required, for their use according to the specification, in the form of individual sheets, in which the form as are most commonly A4 at 297×210 mm or letter size at 297×216 mm. Insofar as a simple integrated card or label is merely available here in the partial print carrier B in the usual check format of 85×54 mm, these are half as wide as the partial print carrier B, even if these are arranged at the short end of the A4 or letter format. More than half of the considerably more expensive materials for partial printing carried B are not taken advantage of in this case, compared with partial print carrier A.  FIG. 2   b ) shows this case. In contrast, a construction, as shown in  FIG. 9   a ) and in which partial print carrier B extends over only half the short end of the print-carrier sheets or partial print carrier A is fully taken advantage of in practice.  FIG. 9   b ) shows the same print-carrier sheets simply folded together, whereby only the half-wide partial print carrier B is supported and protected by the full-width partial print-carrier A and in this case is without problems, for example, in being able to be inserted in an envelope. 
     Hereinafter a method is explained with which print-carrier sheets  92  of the type in  FIG. 9   a ) can be efficiently and in a practically waste-free manner produced in a continuous process. In this method, three partial print-carrier webs A 1 , A 2 , and B 1  operate at the same time, in which the partial print-carrier webs A 1  and A 2  are arranged on either side of the partial print-carrier web B 1  and with it are each joined coplanarly in a manner described according to the invention as a three-part print carrier A 1 /B 1 /A 2 . 
     The method can be executed with a device corresponding to  FIG. 2   a , with die-cut units I, II, and III, whereby additional units simply have to provided for supplying and connecting the third partial print-carrier web A 2  to the partial print-carrier web B 1 . The unwinding of the partial print-carrier web A 2  can occur on the same line as for the partial print carrier A 1 . The attenuation of the edge strips, the different die-cut units, and the adhesives must be doubled.  FIG. 9   c ) shows plan views of the webs A 1 , A 2 , and B 1  in a run through units I-IV of a correspondingly constructed device. The middle web B 1  is, for example, a multi-layer laminate according to that of  FIG. 5 , which is especially suited to manufacture integrated cards  12 . Both of the outer partial print carriers A 1 , A 2  can be paper webs.  FIGS. 9   d ) and  e ) show the resulting three-part print-carrier web A 1 /B 1 /A 2  respectively in section C 1 -C 1  of  FIGS. 9   c ) and C 2 -C 2  of  FIG. 9   f ). 
     Print-carrier sheets  92  corresponding to  FIG. 9   a ) lie in pairs in the three-part print-carrier web A 1 /B 1 /A 2  oriented oppositely. The parting line  93  between the facing print carrier  92  runs alternately along the outer edges of the middle partial print carrier B 1 , as is indicated in  FIG. 9   e ) and in between crosswise through the middle partial print carrier B 1 . By means of appropriate trimmings and die-cuts of the print-carrier web A 1 /B 1 /A 2 , the print-carrier sheets  92  are obtained from the print-carrier web A 1 /B 1 /A 2  corresponding to  FIG. 9   a ). 
       FIG. 9   f ) shows a plan view of the print-carrier web A 1 /B 1 /A 2  in a run through a die-cut unit V of the same device. In this die-cut unit V, for example, by means of one of the die-plates arranged on a magnetic cylinder, individual print-carrier sheets  92  corresponding to  FIG. 9   a ) are cut out in pairs from the running web A 1 /B 1 /A 2 , in which the parting line  93  between the facing print carriers exhibits the shape of a right-angled curve, as has already been mentioned, running alternately along the outer edges of the middle partial print carrier B 1 . These are represented in  FIG. 9   f ) as dashed hidden lines. At the same time, the print-carrier sheets  92  in the die-cut unit III are also cut in the desired format (die-cut lines  94 ), in which a die-cut grid arises. By turning each print-carrier sheet  92  in each pair of sheets contained, all the print-carrier sheets  92  can be brought to cover one another and be stacked respectively with the partial print carrier B 1 , for example, at the lower right. 
     It would also be possible to simply undo the three-part print-carrier web A 1 /B 1 /A 2  in the die-cut unit III along the parting line  90  into two opposing webs A 1 /B 1  and B 1 /A 2  a and to wind these up, for example, for further continuous processing later. Likewise it would be possible to lengthen the print-carrier sheets without outside cuts by simple cross-cutting of the web in pairs. 
     The method described above, besides the fact that it allows for practically waste-free manufacture of print-carrier sheets according to  FIG. 9   a ), is also for that reason highly efficient, because the print-carrier sheets according to  FIG. 9   a ) always occur in pairs. A pair-wise production of “normal” print-carrier sheets, for example according to  FIG. 2   b ) is, in contrast, not so readily possible, because the printing or web-finishing machines, as are usually used in the manufacture and processing of print carriers according to the invention, exhibit a standardized width of only 520 mm. This is not sufficient to allow for running two webs with a width corresponding to the height of an A4 format next to each other. In the method described for manufacture of a three-part print-carrier web A 1 /B 1 /A 2  of a print carrier according to  FIG. 9   a ), however, parts of the middle web B 1  are attached at the parting along the parting line  93  alternating the two outer webs A 1 , A 2 . The finished two-part print carrier A 1 /B 1 , A 2 /B 1  can consequently exhibit a total height corresponding to the height of the A4 format, although the three-part print carrier A 1 /B 1 /A 2  exhibits a clearly smaller width, in particular a width of less than 520 mm. 
       FIG. 10   a ) shows a further print-carrier sheet  100  in plan view according to the invention, in which the partial print-carrier B extends only over half of the short end of the print-carrier sheet or the partial print carrier A. A folding card B is integrated here into the partial print carrier B, parts of which are indicated as  102  and  103 . Above part  102  of the folding card  101  there runs, parallel to the overlapping edge strips of parts A and B, moreover, as an optional addition, a magnetic tape for information storage. Also, these print-carrier sheets can be manufactured with the method described above out of a three-part print-carrier web, in which even reading and writing on the magnetic tape  104  could already occur on the running print-carrier web. 
     The layered construction of the print carrier  100  is apparent from  FIG. 10   b ). With the partial print carrier A, a simple, edge-attenuated paper layer can be handled, as is further represented. The partial print carrier B is a multilayer laminate and exhibits, from top to bottom, a layer  105 , made of a synthetic film, for example, an adhesive layer  106 , a layer  107  made of paper, for example, a further adhesive layer  108 , a silicone parting layer  109 , and a carrier layer  110  made of paper or film, for example. Along an edge strip of the partial print carrier B is a strip with layers  109  and  110  of the adhesive layer  108  removed and the partial print carrier B is glued overlapping there with an attenuated edge strip of the partial print carrier A by using the adhesive of the adhesive layer  108 . By means of a web-less rotating die-cut  111  in the layers  105 ,  106 , and  107 , extending downward maximally to a carrier layer  110 , the folding card  101  is cut free relative to the outside perimeter of their two parts  102  and  103  and can be removed from the partial print carrier B due to the separation properties of the parting layer  109 , as  FIG. 10   c ) shows. 
     Along the bonding line between the two parts  102  and  103  of the folding card  101  a further die-cut line  112  is available as a folding aid, which is executed in the layer  105  as a fully penetrating cut, in the layer  107  in contrast as a perforation with webs, and/or in this layer as an end not fully severed. Both parts  102  and  10  thus simply hang together above the layer  107  and in this also above only individual webs and/or above a certain residual thickness. This is recognizable in  FIG. 10   d ), where the cut line of the picture is selected in the area of a die-cut web  113  between the two parts  102  and  103 . 
       FIG. 10  shows the finished folding card  101 , folded together and glued, relative to its parts  102  and  103 . Here the layers forming, which originate from the layer  105 , external and therefore the covering layers of the folding card  101 , have no bonding to one another. Their encircling smooth and web-less cut edge in essence defines the outer contour of the folding card  101 . The inner webs  113  between the layers serving as the core layers of the folding card, which originate from the layer  107 , are in contrast barely recognizable and are practically unnoticeable by touch. The folding card  101  thus gives as a whole, in spite of the webs  113  present, the impression of a generally web-free card. This is particularly pronounced if the covering layers are of a relatively thick and rigid film and the core layers are of a thinner paper layer in comparison. For machine reading and writing of the magnetic tape  104 , a certain rigidity should be available anyway in the finished folding card  101 . 
       FIG. 11   a ) shows a print carrier A/B of two laminar partial print carriers A and B, joined coplanarly with mutual overlapping, similar to the print carrier A/B of  FIG. 1   g ). The partial print carriers A and B are not further specified as to their construction in  FIG. 11 . Actually, there could be a single paper layer in both of the partial print carriers. One of the partial print carriers could also be a multilayered laminate, such as, for example, that represented for partial print carrier B in  FIG. 1  and used to make integrated cards in  FIGS. 2  and  3 . 
     Both partial print carriers A and B in  FIG. 11   a ) are attenuated on an edge and are mutually overlapping and coplanarly joined together at their edge strips  205  and  206  by means of a special double-sided adhesive strip  210 . The double-sided adhesive strip  210  exhibits two outer adhesive layers  211  and  212  and in between a supporting layer  213 , which can be a simple film layer. 
     A transponder can be used as supporting layer  213  to provide the print carrier A/B of  FIG. 11   a ) with additional functionality and thereby with a added value. Transponders, which are also called RFID-tags, are passive memory chips without own power supply but with an antenna for wireless coding with information respectively for wireless reading of Information stored in the chip. Such transponders are usually constructed by several thin film layers laminated to each other (not shown in  FIG. 11 ) and can, according to prior art, be produced sufficiently thin, as well as in the form of strips with e.g. a width of only 10 mm and a length of approximately 100 mm, to be suitable for the present application. A partly or even complete typographical production is possible. 
     A strip-like transponder  213  is provided between and covered from both sides and protected by the two edge strips  205  and  206 , wherein the print carrier of  FIG. 11   a ) is printable on its entire surface from both sides. The transponder  213  between the two edge strips  205  and  206  does not provoke a local larger thickness of the print carrier A/B, as compared to a print carrier where the transponder would be glued like a label onto the print carrier or laminated in between two layers as it is common according to the prior art. In the later case the transponder should have the same area as the entire print carrier or compensating layers should be laminated together with and next to the transponder to avoid the difference in thickness. Both would not be very economical. The same would apply to laminating a transponder between to paper layers of the same size in the area of an attenuated strip in one of or both paper layers. 
     The print carrier of  FIG. 11   a ) can be produced with the device of  FIG. 2   a ), provided that a laminate e.g. according to the partial print carrier B of  FIG. 1  is used as web B. If a mere paper web should be used as web B then, to obtain an attenuated edge strip, a die-cut unit should be used for the second die-cut unit II, which is constructed like the first die-cut unit I. The transponder  213  would then be applied with pressure onto the attenuated edge strip  6  like the adhesive  11  of  FIG. 2   a ) in station III through the roller pair  33 ,  34 , and the transponder would be fed as endless web from a feed roll  35 , on which it is arranged between the two adhesive layers  211  and  212  as well as two covering layers of silicone paper S 2  and S 3 . 
     In order that the transponder comes to lie correctly in the sheets produced in die-cut unit V, it must be suitably dimensioned with respect to its length and set in correctly. The insetting can be obtained by means of a so-called insetting group (not shown), which is arranged between the feed roll  35  and the roller pair  33 ,  34  and through which the transponder web can be slightly more or less stretched if required. For the insetting, the transponder web must be provided with insetting marks. 
     In case that the transponder should be incorporated in print carrier sheets  92  of the type of  FIG. 9   a ) with a A4 or letter size format, the length of the transponder should correspond only to half the width of the print carrier sheet so that one transponder is placed per print carrier sheet. 
       FIG. 11   b ) shows an embodiment according to the one of  FIG. 4   a ), wherein here the two edge strips  205  and  206  do not mutually overlap and are joined together with an adhesive strip  215 . The adhesive strip  215  comprises a covering layer  216  in particular of paper, an adhesive layer  217  as well as a transponder  218  in between these two layers according to the one in  FIG. 11   a ). Here, the transponder  218  is also integrated in the print carrier A/B in a covered manner and does not provoke a local larger thickness of the print carrier. 
     The print carrier of  FIG. 11   c ) is a modification of the print carriers of  FIG. 11   b ), wherein here an adhesive strip according to the adhesive strip  215  with transponder  218  of  FIG. 11   b ) is glued only along the attenuated edge strip  205  of the partial print carrier A. 
     This embodiment is suitable if a partial print carrier A should be provided with a transponder without thickening and the partial print carrier B would not be of additional use. The adhesive strip  215  containing the transponder could also be seen as a special kind of partial print carrier B, which merely lacks a thickened part. 
     The print carrier of  FIG. 11   d ) is a modification of the print carrier of  FIG. 11   c ), wherein here an adhesive strip according to the adhesive strip  215  with transponder  218  of  FIG. 11   b ) is glued along an attenuated strip  221 , which is not an edge strip anymore, of only one print carrier D of a paper layer  220 . The attenuation along the strip  221  can be produced by tearing off a strip-like partial layer e.g. after previously providing the print carrier D with two parallel cuts, as already described e.g. for the attenuated edge strips  5 ,  6 . 
     The examples explained above are in no way to be understood as conclusive. Rather, they merely clarify that the present invention can be applied with a plurality of differently constructed partial print carriers and that within the framework of the present invention, even the most diverse integrated products can be made as a result. 
     In order to avoid skewing in the stack, the two partial print carriers joined together should have the same thickness whenever possible. However, certain thickness differences can be tolerated. The resultant planar position for a thickness difference of up to at least +/−5% will be sufficient for most applications. 
     Integrated cards, folding cards, or labels typically exhibit dimensions of 55 to 85 mm, so that the partial print carrier B preferably used for their manufacture can exhibit a width of 80 mm. If the partial print carrier B in a print carrier A/B according to the invention, for example, is arranged in the format of an A4 sheet along one of its short sides, the partial print carrier A will definitely have a height of more than 200 mm, so that the partial print carrier A, which can be made of an economical paper material, will constitute the largest part of the surface of the print carrier A/B. 
     In all the embodiment examples described above, the differentiation along the edge strip of the partial print carrier B, if this is a multilayered laminate, could also be achieved by measures other than attenuation by removing individual layers, in particular, when making the laminate itself. 
     In the method explained with the aid of  FIG. 2  and  FIG. 9 , print carriers A/B with integrated card according to the invention could be made in a single run, whereby the method and the device used for it have to be modified somewhat according to the layered construction of the partial print carrier used. So, for example, to make the print carrier of  FIG. 8 , no extra adhesive strip K 1  or any adhesive  11  is needed. Also, an adhesive could already be present in web A, and after exposing this adhesive, only a small uncoated strip would have to be applied. If need be, tearing off the partial layer of the paper layer can also be done entirely without the aid of an adhesive strip. It would also be possible to use the first die-cut unit of  FIG. 2  exclusively with its additional units and to simply create a paper web attenuated at its edge in a single run, which could even be delivered to another manufacturer as starting material for further processing later. This attenuated paper web could also be already provided along its attenuated edge strip with an adhesive layer covered by a detachable covering layer. 
     What has been described above are preferred aspects of the present invention. It is of course not possible to describe every conceivable combination of components or methodologies for purposes of describing the present invention, but one of ordinary skill in the art will recognize many further combinations and permutations of the present invention are possible. Accordingly, the present invention is intended to embrace all such alterations, combinations, modifications, and variations that fall within the spirit and scope of the appended claims.
