Abstract

The invention concerns a device and a method for dispensing parts (12) of a material to be distributed (23) on or into a moving printer carrier (15). The device comprises a dispensing cylinder (29) and a counter-cylinder (28). Between the dispensing cylinder and the counter-cylinder, a cut is performed using at least a cutting member formed on at least one of the two cylinders and rotating with said cylinder(s). The parts (12) are brought, by rotating the dispensing cylinder (29), on or in the printing carrier (15). The parts are quickly, accurately, easily and simultaneously dispensed, cut and the printing carrier (15) is precisely adjusted by virtue of the fact that the cutting member is in the form of a narrow cutting edge (25b). Said device and said method are suited, among others, for producing forms with integrated card, such that, for example, the laminated material (12) dispensed on the back of the form is arranged in such a way as to cover almost completely the card surface and its outer edge has a contour corresponding substantially to the cutting line (34) of the card.

Description

TECHNICAL AREA

The present invention relates to the field of form production. It concerns a Form with detachable card according to the preamble of claim 1.

In addition, the invention also relates to methods for manufacturing Such forms according to the preamble of the claim 5th

STATE OF THE ART

Forms of the type mentioned are known from WO 98/13213.

In the film and print carrier processing are often films or papers, in different shape and design on continuous tracks or in holes in these eingespendet. Especially in the labeling area, in the area of printed forms and in the field of printing Production of integrated cards is increasingly gaining importance for such processes. This is partly because the demand for different Print media qualities and properties on a form sheet under optimal Exploitation of various high-quality materials in customer circles is increasing.

For applying foils or papers to an endless web or to print carrier sheets usually find methods, as described for example in WO 97/16370 (Hunkeler AG) are described, application. The donor material is supplied in the form of a web and between the donation cylinder and one equipped with cross cutter Cutter cylinder cut to length. The resting on the donation cylinder parts are then transferred as a result of the rotation of the dispensing cylinder on the print carrier and stick to this over an adhesive layer. To the parts on the dispensing cylinders During the rotation, they are usually designed as suction cylinders. WO 97/16370 mentions as an alternative to this also holding the aufzuspendenden parts on the donation cylinder by electrostatic forces.

Often, the print media after the Aufspendung cut parts of a Donation material are additionally punched in the field of Aufspendung, so for example, in the production of integrated cards. This is usually done immediately after the Aufspendung in a subsequent operation, whereby the adjustment (Register control) between these two operations, especially at fast Make productions difficult. So usually the area of the donated is Materials generously designed to overlap the card to ensure that too relative shifts of the work always the card as a whole of the Overlapping is covered.

PRESENTATION OF THE INVENTION

The invention is inter alia the object of a form with herausrennbarer Map to provide, which in particular in terms of optical appearance of the card is improved. This task is at a Form of the type mentioned solved by in the characterizing part of claim 1 specified characteristics.

The layer material is therefore limited at least approximately by the punching line of the card and it is based on overlapping the feed over the punched card edge completely or essentially omitted. The map appears to the viewer in Form borderless and visually offers over the versions according to the state of Technique a much improved appearance.

Another object of the invention is to provide a method for To provide which the production of forms allowed according to the present invention. This further task is added solved a method of the kind mentioned through the im Characteristics of claim 5 specified characteristics.

In particular, the burrs directly on the cylinder surface (so-called. Rotary punches, cylinder whose cylinder jacket leaving the punching burrs something is milled down, i. the burrs are an integral part of the cylinder and unadjustable in Height and positioning) or preferably on one, on the cylinder surface In particular, formed magnetically adhering thin stamped sheet, so can the Dispensing process can be run at high speeds, without affecting the punching height or punching position often need to be readjusted. Accordingly, reduce this also the registration problems. Furthermore, the burrs, as they are not as Cross cutting blade are formed, curved, and in particular preferred be formed at least approximately self-contained lines forming. These Design allows, for example, the punching and donating parts whose Outside edges have any shape.

A preferred embodiment is characterized in that the donor material resp. the parts are punched and / or punched between the donation cylinder and a counter cylinder be and that then the parts by rotation of the dispensing cylinder on the Form be conveyed. It can also be provided that the form between the dispensing cylinder and a another counter cylinder out there and using at least one on the further counter-cylinder formed cutting edge is punched from below. To cut can thus be present on several cylinders, so that the parts and / or the Form from different sides on different outlines on and / or can be punched out. Such an arrangement is extremely flexible and allows the Application of extremely versatile shaped and punched dispensers.

Are cutting provided on the dispensing cylinder and are further both a Counter cylinder as well as another counter-cylinder of the type mentioned exists the special advantage that with these cutting both in the gap between the Donation cylinder and the counter-cylinder as well as in the gap between the Spendezlinder and can be punched the other counter-cylinder. It can therefore be used with these cutting edges Gap between the donation cylinder and the counter cylinder, e.g. from a donation material a part off or punched, this below according to the invention by the rotation of the dispensing cylinder and quasi-embedded in the cutting on the form and the Form in the gap between the dispensing cylinder and the other counter-cylinder the same also be punched as well as the same contour with this part of the donor side. On this way, the steps of the Aufspendes a Spendenaterialstücks on the form and punching the form in a combined step be summarized. The so combined donning and punching of the form is also referred to as "dispensing punching" in the following. That according to the invention On the back of the form located carrier material is in this process also punched.

This results in advantage also a significant mechanical engineering simplification in that instead of two, in the prior art always separate and usually also still on separate machine racks realized modules, namely a donor module on the one hand and a punching module on the other hand, only a single module needed which can be referred to as a "dispensing punch module". In addition, it eliminates this also guide elements for the continuous web (such as a turning module), as between The donation and the punching module have always been used. By the Summary of the functions Donations and punching in a module are won course also space and installation area; the space saving can in the direction of the Continuous run several meters.

Another embodiment is characterized in that at least one, but especially preferred all of the cylinders are magnetic cylinders that the punching burrs as Punching plates are formed, which punching plates on the cylinder surface of the Cylinder resting base plate and at least one substantially perpendicular to Base plate and with respect to the axis of the dispensing cylinder radially outwardly extending Cutting line, and that the punching plates by magnetic interaction the magnetic cylinders are adhered attached. Such burrs allow a fast and extremely flexible cutting of the parts with low adjustment of the Machine. In addition, they allow easy use of circulating Cutting lines, which, for example, when applying in the area to the Dimensions of an integrated card matched feeds proves favorable. Will continue to the zuzuschneidenden facing side edges of Punching burrs formed substantially perpendicular to the cylinder plane, so that the at Cutting resulting cut edges of the parts substantially perpendicular to the surface the parts are aligned, so can a sometimes occurring "bleeding" of for the Adhesion of the donor material on the print carrier used self-adhesive avoided Be: So there are no annoying glue residues in the edge area of the Aufspendung.

Another embodiment of the invention is characterized in that the Donation cylinders are designed as suction cylinders, and so that the adhesion of the parts during the rotation of the donation cylinder is effected. Also possible is the electrostatic fixing of the parts on the dispensing cylinder. Preference is given to the Cylindrical surface of the dispensing cylinder in the direction of rotation of the dispensing cylinder in substantially immediately prior to detecting the parts from a first sword electrode electrostatically polarized. It may also prove advantageous if a first Sword electrode the supplied donor material just before cutting through the Cutting agent is electrostatically polarized from the side of the self-adhesive layer. Or but it can be the cylindrical surface of the dispensing cylinder and the parts lying on it Rotation direction of the dispensing cylinder substantially immediately after the detection of the Parts of a second sword electrode are electrostatically polarized.

An additional embodiment is characterized in that the stamped sheet Has bores which at least partially via suction holes of a suction cylinder are arranged and which allow the formation of a negative pressure, wherein the Holes particularly preferably substantially immediately in the direction of rotation of the Dispensing cylinder are arranged behind a front cutting line and which continue preferably have a distance of the bore centers, which more than two times so big is like the diameter of the hole. So the donation part becomes immediately at the beginning the punching operation detected by the donation cylinder, and said spacing allows In addition, any distance between lateral cutting lines, without that Suction holes of the suction cylinder come to rest under the lateral cutting lines and thereby deforming them. If the sheet is still magnetically preferred as on Donation cylinder fixes and becomes the sucking property of to some extent as magnetic suction cylinder designed dispensing cylinder only for holding the dispensing parts used, so there is the further advantage that the sheet when switching off the suction pump does not fall off the role.

According to the invention, the donor material is on the lower side facing away from the dispensing cylinder at least partially with a Self-adhesive coated, so that the parts due to the adhesive effect of Self-adhesive layer stick to the form. Furthermore, as a train supplied donor material on its provided with the self-adhesive layer side einern Covering material should be covered, this cover material on its self-adhesive layer facing side be provided firmly connected to a release layer, and the Cover material together with the release layer before or substantially during or but also detached after cutting from the self-adhesive layer of the donor material web and be dissipated. Thus, donor material can be fed in a roll form in a simple manner and without much technical effort, i. without in-line gluing or similar Processes are being dispensed. The delivery of donor material can be done in most Cases also occur intermittently, the donor material substantially only is transported when the first means are about to cut a part and the part is detected by the donation cylinder. If necessary, a step backwards can also be installed in which the donor web is not punched in the non-punched something is transported backwards. Thus, the formation of unnecessary waste at the same time easy to be avoided. The regression process can also be beneficial used to increase the positioning accuracy of the donor in general become.

Further embodiments of the form and the method emerge from the dependent form and method claims.

The form according to the invention is characterized, as stated above, in that the Layer material essentially exclusively covering the area of the card and with respect to its outer edge, substantially in line with the punching line of the card is arranged, i. that on an overlapping of the Aufspendung over the punched Card edge is completely omitted or at least substantially. Technically it is possible Such a form particularly simple with one of the devices described above or produce a method described above, as in these the most accurate Punching and Aufspendung can be easily realized. In addition, it can be with it previously applied on the form, if necessary also edged in the same shape, prints relatively light and without big ones Combine registration problems, which further enhances the visual effect.

WAYS FOR CARRYING OUT THE INVENTION

Figure 1 shows a simple schematic representation of a Aufspendmechanismus, in which parts 12 are detected by a dispensing cylinder 13, here designed as a suction cylinder, cut from at or in the donation cylinder 13 fixed cutting lines 25b, and then be aufgespendet on an endless track 15.

A donor material laminate 20 is inserted from a roll, which is one with a Self-adhesive layer 22 provided donor material 23 and on the self-adhesive layer 22nd applied cover material 24 with release layer 21 includes. The donor material 23 can while film, paper, or even a multilayer laminate of the be different materials. It is of course also possible, the donor material fed in unglued form and to some extent make an in-line gluing. But it turns out to be a lot easier for a lot of producers to do that Donate material just from role as glued donor material web supply and the Rolls from a company specializing in self-adhesive coatings allow.

In a first step, the cover material 24 is separated via suitable rollers 19 and dissipated. The remaining donor material 23 is then with its unprimed Side facing the dispensing cylinder 13 in the gap between the dispensing cylinder 13 and a counter-cylinder 10 out. The counter cylinder 10 can be partially in the zones, against which attached to the donation cylinder 13 cutting lines 25b during rotation of the two cylinders come to rest, be provided with counter plates 11. The parts 12 are so between counter cylinder 10 and donation cylinder 13 from the cutting lines 25b, which may be designed circumferentially or as a cross cutter, isolated. One optionally formed stamped grid 26 can be easily removed behind the gap. The supply of the donor material web 23 can also be designed intermittently, for example, by advancing only when the cutting lines 25b are in the process of tailor. Thus, the spacing of the attached parts 12 can be optimally adjusted and the waste of donor material 23 can be reduced. It could even be one Back step between each two feed movements are executed.

The concurrently with the fed endless web 15 at least at the moment of dispensing co-rotating suction cylinder 13 transports the parts 12 by its rotation on the Endless web, wherein the parts 12 during rotation by the sucking negative pressure at Stick cylinder 13. Advantageously, the suction cylinder 13 should be adjusted be that the suction in the donation area is interrupted briefly to ensure that the parts 12 are not on the cylinder after contact with the endless web 15 13 adhere to. During the dispensing, 25b will be at the same time as the punching line the endless web 15 on or punched out. This is done in counter-pressure against a Pressing roller 16. This gives rise to the possibility of those contour sections of the stocked up, in which this is desired, the blank of the parts 12 and the Punching the endless web 15 in the process of course natural given precision to one another. In this way, for example without large register settings from the endless web 15 new forms with integrated cards are produced, in which the material aufgespendete at least in areas practically exactly the same contour with the punching of the card is executed and on an optically unsightly overlap of the donor material on the punching lines addition can be dispensed with. It's not just more appealing products, it's what you get In addition, donation material 23 can be saved.

Most cutting tools for cutting parts of the prior art are cutting cylinders used in which knives are embedded in knife grooves. As a cutting cylinder acts according to the state of the art, not the dispensing cylinder, but the overhead one Counter cylinder, i. the attachment of the cutting means is reversed. The u.U. different speeds of donation cylinder and cutting cylinder, which itself additionally one of the conveying speed of the dispensing material 23rd may have different speed to adjust the length of the parts 12 have previously hold on to this technique. But such cutting cylinders have for in This embodiment described in which the cutting cylinder also at the same time donation cylinders are to be, a number of disadvantages: the in their height adjustable knives often need to be readjusted. For example, e.g. a readjustment of the Knife in the grooves needed when the speed of the process is changed, but also when the donor material 23 changes in thickness or composition. Moreover Of course, only knives can be arranged where in the Schneidzylindem Also grooves are provided, which limits the setting of cutting to length.

In addition, it turns out that the flow rate of such cutting cylinders is quite limited, which in connection with the sketched in Figure 2 Embodiment therefore particularly as limiting effect because with electrostatic Adhesion of the parts 12 on the dispensing cylinder actually higher throughput speeds would be possible.

It turns out that the above problems can be effectively resolved by: as donor cylinder 13, a magnetic cylinder is used, on which punching plates 25, in Figure 1 e.g. in transverse cutting line, or else in circumferential cutting line, magnetic are adhesively applied. The punching plates 25 consist of a base plate 25a, which adapts to the cylindrical surface in its rounding, and which on the Cylinder surface rests, so that a good magnetic adhesion of the punching plate 25 on the Magnet cylinder 13 is possible, and a cutting line 25b extending thereon. Most will be like this a punching plate 25 made by a sheet of, for example, about 0.5 mm thickness below Omission of the cutting line 25b to a thickness of, for example, about 0.1 mm is etched down. Thus, the resulting base sheet 25a has a thickness of about 0.1 mm, and the cutting line 25b protrudes 0.4 mm beyond the base plate 25a. The Cutting line 25b is also ground after etching for sharpening. Such Punching sheets are used in labeling technology for the stamping of labels, there but only under conditions in which the good to be cut and the Magnet cylinder rotate at the same speed, thus dislodging the punching plates 25 can hardly occur on the magnetic cylinder. In addition, in the labeling technology The pre-processing and subsequent Aufspendung fundamentally different approach. In a first operation is a donation material laminate, off-line, respectively printed and punched out, leaving only the labels on the cover, the Punching grid, on the other hand, is removed. In a next step, the on the Covering adhesive labels passed over a sword, the cover material separated and donated.

The use of the cutting technique with magnetic cylinder 13 and punching plates 25 for Cutting or punching and donating parts 12 and endless web 15 or Print carrier sheet proves to be surprisingly easy. To stick the parts 12 to avoid punching sheet edges, may also preferably a roller of porous Foam are provided. This roller is soaked with silicone oil and runs with the Magnetic cylinder 13 in an exposed position with such that the punching plates 25 at Circulation of the magnetic cylinder 13 are each wetted with silicone oil. It is important that only the cutting lines 25b, but not the base plates 25a in contact with the Foam roller come, otherwise the parts 12 u.U. be provided with silicone oil, which can disturb the subsequent processing. The use of magnetic cylinders 13 is independent of speed and material, stable and no readjustment necessary. she can be used in this application both as suction and in electrostatic Use fixation technique. In addition, with magnetic cylinders can easily high Speeds are driven, the cutting process is therefore no longer rate-determining. While cross-cutting knife according to the prior art usually are not able to produce thick materials of more than 0.1 mm at high Speeds to cut (a problem, especially with polyester films occurs), punching plates 25 can also be used without problems at thicknesses of up to 0.2 mm become. Magnet cylinder 13 with punching plates 25, both in the accuracy of a few Thousandths of a millimeter are available as state of the art, thus permitting the application of the Cutting to length of supplied laminate gives higher precision, stability and longer life Machine and thus higher efficiency of the process.

Another particular advantage of using punching plates 25 of the type described is that in a simple way any stamping can be realized because the Line guidance of the cutting lines on the stamping plates, of course, is freely selectable.

Unless there is flexibility in terms of punching and its location in the concrete Use case does not matter, could of course also for the donation cylinder Cylinders are used, in which the desired cutting lines on the type of Punching plates, but incorporated directly into their surface (e.g., CNC milled Rotary punches).

Also could be used such cylinders, which partially only with magnetic surfaces are equipped, but otherwise at least one non-magnetic steel surface exhibit. Depending on the task, these cylinders could be used for magnetic attachment of punching plates and / or (without counter plates) are used directly as counter-cylinder.

Figure 2 shows a schematic representation of a Aufspendemechanismus with electrostatic adhesion of the parts 12 on a dispensing cylinder 29. As above in Figure 1 described a donor material laminate 20 is introduced from a roll, which with a a self-adhesive layer 22 provided donor material 23 and a on the Self-adhesive layer 22 applied cover material 24 with release layer 21 includes. The Donor material 23 can again slide, paper, or even again multilayer laminate of various materials. The cover material 24 is first removed and rolled up and the donor material 23 with exposed Self-adhesive layer 22 is detected by a tension roller 17 and the pressure roller 18 and clocked. For exact timing of the donor material web 23 may continue a first Photo mark reader 27 may be provided, which on the donor material 23 existing Photo stamps read and these with corresponding photo marks, which from a second, are read on the endless web 15 arranged photo mark reader 31, coordinates. In addition, in the case of the separation of parts 12 over the entire width of the Donor material web 23 as well as the rotational speed of the dispensing cylinder 29 and so that the separation length can be optimally adjusted. The donor material 23 is after the Pull roller 17 is guided between the dispensing cylinder 29 and a counter-cylinder 28.

The dispensing cylinder 29 may optionally be coated with a dielectric layer be. This layer can be made of a non-metallic material such as lacquer, ceramic, synthetic resin or other plastic. Particularly good adhesion values, for example, with a Polyester film of a thickness of 50 microns and a Acrylatdispersionskleberschicht of 20 microns reached. The dielectric layer may additionally be prior to receiving the parts 12 of FIG electrostatic polarization of an additional sword electrode (note here but that from this the danger of injury by one as a result of Potential difference between earth and cylinder 29 possible spark jump at Touching the cylinder 28 after turning off the machine). Before the Cutting the parts 12, the donor material web 23 of the self-adhesive layer having electrostatically polarized side from a first sword electrode 30, and after receiving the parts 12 by the donation cylinder 29 after a partial Rotation of the dispensing cylinder 29 is electrostatically fixed a second time, with a second sword electrode 32. The first and the second sword electrode act thereby rectified polarizing, and the second sword electrode thus acts adhesion reinforcing. Voltages of approx. 15 kV are used. These electrostatic polarization is sufficient to keep the parts 12 from picking up to delivery to adhere well to the donut cylinder 29 on the endless web 15. Self-made Papers or laminates, which for better printability a much shorter cooldown have the electrostatic charge, so can be easily aufgegespendet. In particular, the fact that not the aufzuspendende material, but permanently the Donation cylinder 29 is electrostatically polarized, allows a better transport of conductive donor materials.

The presence of the sword electrodes 30 and 32 offers no user-friendly Disadvantages, since all trimming omitted. The arrangement of the electrodes 30 and 32 is uncritical when the magnetic cylinder 29 is electrically isolated and thus at the moment of Can take place no derivation of the charges (the cutting lines 25b should never touch the counter cylinder 28 anyway). Likewise, care must be taken that no other grounded machine parts so close to the dispensing cylinder 29 or the Sword electrodes 30 and 32 come to rest, that is a derivative of the charges can take place. It is important, of course, that when you turn off such a system the electrostatic charges are dissipated immediately.

The electrostatic adhesion of the parts 12 on the dispensing cylinder 29 can of course be effected in many ways. This is the case, for example, with certain donor materials the polarization of the parts occurring when removing the covering material sufficient. On the other hand, it is also possible to isolate the donation cylinder 29 and under tension and replacing the sword electrodes 30 and 31 with grounding contacts. alternative can also be the counter-cylinder 28 used as a sword electrode or grounding. The Size of the dispensing cylinder 29 is to be chosen so that the maximum dispensing length with Reserve between cutting line and Aufspendelinie on the circumference of the dispensing cylinder 29th Takes place.

On the continuous web 15, or the continuously supplied form sheet can already applied or donated before the donations considered here are located. So, to follow the example of integrated card forms, even before the upper side of a simple foil 43 which is considered here on the underside a carrier material 44, covering the area of the card, be applied, and in the case of the dispensing of the top-side film, the continuous web 15 and the carrier material 44 be punched. If you put the cutting and the donation of the upper Aufspendung 43 accordingly, so integrated cards can be produced, which in optical extremely appealing way on the top side only covering the area of the card from one Slide 43 are covered. Such a novel, surprisingly simple, and for the end user pleasantly intuitive integrated maps with just just the area of the map Covering dispensers are also known per se with sequential methods, e.g. under Use of the latest laser technology for cutting the continuous web can be produced. The above described method proves but just for this new design of the integrated Cards because of the omission of the otherwise especially in fast runs difficult relative adjustment of the individual dispensing and punching steps (registration) as particularly suitable.

In the examples of FIGS. 1 and 2, the cover material 24 has been removed from the donor material 23 each deducted and removed before cutting the parts 12. Especially if the cutting of the parts 12 cutting with the retention of a punched grid 26, this is an advantage because then the corresponding layers are safe and clean separate from each other. However, this comes by pulling off the Covering material 24 exposed self-adhesive layer 22 inevitably in contact with subsequent device parts such. B. the pressure roller 18 and the counter cylinder 10th in Fig. 1. So that the donor material does not stick to these elements, they must be equipped with dehäsiven surfaces. Corresponding surfaces are in the state of Technology known and are available in principle.

FIG. 5 shows dispensing mechanisms in which the covering material 24 only after the Cutting the parts 12 removed and thus the aforementioned problem and the Need to equip device elements with dehasive surfaces from is avoided in the first place. However, this must be done, if necessary by additional measures, ensure that the parts 12 aufzuspendenden after cutting safely and easily from the cover material 24 and from any punched grid 26 solve to to be taken over by the donation cylinder at all. As such additional measure in the example of Fig. 5, the donation material laminate in order Reduce the adhesion between his layers before cutting temporarily pre-separated. In FIG. 5 a), the dispensing material laminate 23 accordingly only becomes one Stock loop 75 unrolled from a roller 66, then taken by two feed rollers 72. Before cutting, the covering material web 24 is now removed from the donor material web 23 separated and only shortly before or in the gap between counter cylinder and donation cylinder again returned to the donor material under the influence of a first air nozzle 69. To the cutting through the cutting plates 25 is immediately behind the gap the Abdeckmaterialbahn 24 withdrawn under the influence of a second air nozzle 70 and the Part 12 transported from the donation cylinder on the web 15. The liability on the Dispensing cylinder is again in this embodiment by means of electrostatic Liability causes. For better adhesion of the parts 12 in the punching plates 25 during the Rotation transport can, as indicated in Figure 5b), a dielectric film 76 between the cutting lines 25b are let in.

The mechanism in Figure 5c) waives a pre-separation. For a safe separation will be Here, however, immediately behind the gap, a separating lip 82 is arranged, which is the Covering material 24 leads around a sharp edge, so that the parts 12 easier to peel off. The Separating lip 82 preferably has a bending radius of approximately 130.degree. R = 1 mm and is curved on its donor cylinder 29 facing bottom formed, so that between her and the donation cylinder a uniformly wider Gap results. Further, this bottom of the release lip is still soft, brush or provided fur-like coating through which the punched parts 12 in contact with the donation cylinder are held, which coating on the other hand but the Punching plate 25 and its cutting lines can dodge. To support the replacement the parts 12 may find a so-called air brush 81 application. The air brush 81 is as Roller formed whose axis is parallel to the axes of the cylinder and itself extends at least over the width of the parts 12. The high-speed operated (up to approx. 5000 RPM) roller is filled with bristles of preferably adhesive repellent material such as e.g. Nylon, teflon or coated metal. On the side facing away from the gap In addition, a brush housing 83 is arranged. The channeling effect of this Brush housing 83 leads to rotation in the same sense to the rotation of the cylinder 28 to Forming an air jet, which the detachment of the parts 12 from the cover material 24th supported.

Instead of a separating lip can also be a separation roller at the appropriate location can be used, which e.g. has a diameter of 12 mm and e.g. from one Shaft with 10 mm diameter with attached sliding bushes, each with 1 mm wall thickness is constructed. This separation roller is then adjusted as close as possible over the punching plate and avoids the friction of a separating sword.

In this embodiment, moreover, not an endless web is fed, but it According to the prior art, paper sheets are continuously passed through a sheet stack 84 removed, processed, and then deposited in another stack of sheets 85. The Guiding the single sheet is done between the two stacks 84 and 85 by two Tractors 73.1 and 73. 2, with the first tractor 73.1 seamlessly connecting the bow to the second Tractor 73.2 passes, such that the bow, when from the second tractor 73.2. detected be held even for a short time by the first tractor, so they always clearly managed and never loose. The dispensing cylinder 29 and the pressure roller 16 here comes to no leadership or transport function to take over the Arch through the punching plate, especially in the presence of transverse Cutting lines goes out. The single sheet transport device is so far as well functional and usable when simultaneous punching together with a Dispensing should be waived in each case once.

An alternative support for the detachment of the cover material 24 is shown in FIG. 5 d). shown. Here the material after cutting only a little on the cylinder 29th along and then around a separating lip with a much higher deflection angle (up to 180 °). Although this arrangement has an ev. Better separation characteristic than the above; as a result of the initial guidance around the donation cylinder, even at intermittent feeding of the donor material web but unused sections between two parts 12, which affect the utilization of the donor material and to lead to increased waste. By one between two feeding steps with the Dispense material web suitably executed backward step, however, this disadvantage can be remedy.

FIG. 6 shows a preferred embodiment of the cutting lines 25b of punching plates 25, which is capable of leakage of self-adhesive 60 after application of the laminate to prevent the endless track. Figure 6a) shows the conditions in the gap between Counter cylinder 28 and dispensing cylinder 29, Figure 6b) that during dispensing on the Endless web 15. This happens such that the inner edges of the cutting plate perpendicular to the base plate 25a are executed, and only the outer edges are chamfered. So Also, the side edges of the part 12 are perpendicular and at oblique edges Occurring superficial presence of self-adhesive is thus avoided.

FIG. 9 describes the gap conditions in a donation according to FIG. 2. From the lower one Side is here before a multilayer substrate 33 applied, stamped and Donated is only from above. It may be the substrate 33, for example, a Material act, as described in EP 836953 and as in the production of in forms integrated maps application finds.

The described method can also be applied if the parts 12 are not of the Donation cylinder 29 are cut to length or cut, but also when the parts 12th for example, supplied in label form or another already tailored form become. For example, on a Abdeckmaterialbahn 24 in tailored form supplied parts 12 can, as shown schematically in Figure 10, from the Covering web 24 are peeled off via a separating lip 82. In this case, the parts 12 in inserted on the dispensing cylinder 29 punching plate 25 is inserted, and then from the cylinder 29 by punching the endless web 15 aufgespendet on selbige. In relation to the balance between peeling of the parts 12 and rotation of the dispensing cylinder 29 proves Such a method is relatively uncomplicated, especially when the parts 12 at a circumferential cutting line of the punching sheet automatically captured to some extent and adjusted that way.

It should also be mentioned that in all embodiments of the described devices the so-called gap dimension, i. the shortest distance between the individual rollers preferably should be adjustable to different material thicknesses with respect to the Print carrier and / or the donor material process and, of course, the respective to be able to adjust the desired punching depths. Where three rollers cooperate, e.g. in Fig. 1, the dispensing cylinder 13, its counter-cylinder 10 and the pressure roller 16, is Preferably, the middle roller (in Fig. 1 of the dispensing cylinder 13) fixedly mounted and this opposite the two outer rollers (in Fig. 1, the counter-cylinder 10 and the Pressure roller 16) mounted eccentrically adjustable.

In addition to Figures 2 and 9, Figure 11 shows a perspective view of a Cut through a form with integrated map, where the top side Ticket Dispatch 12 is designed in the same contour with the outline of the card. On the Underside is a carrier material overlapped around the punched card To hold the form. It is easy to see how the same-sized Aufspendung to a optically and tactually appealing and more intuitive product leads, with the most to one further identification of the card outline and to dispense with removal aids can.

Another preferred embodiment of a stamping sheet is outlined in FIG. The punching plate has bores 100, which are provided to the punched 12th hold on the dispensing cylinder 13. The punching plate 25 rests on a suction cylinder 13, which has suction holes 102. The plate 25 can either further, in the Figure simplified for simplicity not shown suction holes held on the cylinder 13 be, or the suction cylinder 13 may be formed simultaneously as a magnetic cylinder. Magnetic cylinders usually have a structure that also has a subsequent attachment of Suction holes 102 allows: The magnetic material elements are namely mostly segmentwise and in rows parallel to the axis of the cylinder in the cylinder jacket of a Fully cylinder let in. In this case, remain parallel to the axis of the cylinder on the cylinder surface mostly non-magnetic strips of solid cylindrical material which are wide enough are to attach suction holes 102 without the most brittle magnetic material to have to drill. The combination of a magnetic suction cylinder whose absorbent property is used essentially only for the adhesion of the diecut 12, and its magnetic property for holding the sheet 25 on the Is exploited cylinder surface, u.a. the advantage that the punching plate 25th even when switching off the vacuum pump, which generates the negative pressure, still on the cylinder 13 remains liable.

The punching plate 25 has, as described above, a base plate 25a, on which a cutting line 25b is arranged. In the direction of rotation 101 of the dispensing cylinder thirteenth considered there is thus a front cutting edge 25b1, which on the donor material 23rd the punching process acts first, a rear, cutting edge 25b2, which only on End when the diecut is almost completely cut out, and lateral Cutting edges 25b3 and 25b4. It proves to be particularly advantageous, the holes 100th in a row as close as possible immediately behind the front cutting edge 25b1 to arrange, because then the punching 12 immediately at the beginning of the punching process from the vacuum is detected and very efficiently replaced by any existing cover material can. It is unnecessary then the costly pre-separation of donor material and Cover material before punching between donation cylinder 13 and counter cylinder 28th

Of course, the punching plate 25 should be arranged as possible on the dispensing cylinder be that the suction holes 102 and the holes 100 come to lie one above the other. Optimally, the two holes 100 and 102 also have the same Spacing D a same diameter d, or the holes 100 are smaller than the suction holes 102. It is also conceivable that the suction cylinder is not has individual holes, but arranged parallel to the cylinder axis suction slots. If a suction hole 102 of the cylinder 13 immediately below the cutting line 25b3 or 25b4, this can lead to an irregularity in the cutting height of the cutting line lead and negatively affect punching (a typical sheet has a base thickness of about 0.1 to 0.14 mm, and a punching height above the base plate of 0.4 to 0.48 mm). Around To prevent this, it is advantageous to the series holes 100 with a diameter d to to space the distance D, and to make sure that D at least twice as large is like d. So are any distances between the two lateral cutting edges 25b3 and 25b4 possible and also can prevent the suction holes at transversely moving the sheet 25 by mistake directly under the punching lines come lie. Typically, the holes 100 are in a row about 1 mm behind the arranged front cutting edge 25bl, have a diameter of d = 4mm and are spaced by about D = 13 mm apart. To be as efficient and fast as possible Training the negative pressure and thus to promote the suction, it may be also prove useful, not for the liability of the dispensing parts 12 used Apply suction holes 102 or otherwise compact them.

Figure 14 shows an apparatus in which the dispensing material laminate 20 is intermittent transported and in which a further retreat or step back of the Dispensing material laminate controlled between each two feed steps is executable. The withdrawal or regression serves on the one hand, the waste on the donor material web 23 to further minimize the unused areas (lands) between each two diecuts is caused. Another feature is controlling a Brand feeder. This is about a donation provided with brands as possible to be positioned exactly on a print carrier.

The donor material laminate 20 is used in the apparatus of FIG. 14 by a roller 66 of FIG a driven guide roller pair 105 detected and transported. Behind it is a supply loop 75 of the material 23, which of a pair of stationary brush rollers 122 is ended. The brush rollers 122 are pressed against each other and cause a slight braking of the donor material laminate. The braking force is dimensioned so that they just one further transport allowed when a punching process is running. This results in a intermittent feed. To the brush rollers 122 closes a pair of Retraction rollers 123a, b, whose training and function will be described specifically. Subsequently, a guide roller 107 is present, which the web 23 in a specific Angle α between the dispensing cylinder 13 and the counter-cylinder 28 leads, where they punched becomes. With the guide roller 107 can be influenced how long, for example. when using a Punching plates according to FIG. 13, the negative pressure through the holes 100 are constructed can. If the angle α is set small, then the web 20 runs tangentially with it for a little longer the donation cylinder 13 with and there is more time to build vacuum. Behind the cylinder pair 13 and 28, the stamped laminate for separating the aufzuspendenden parts initially passed over a separating roller 121, as described above in Connection with Fig. 5 has already been described. From there runs the remaining Covering material, which optionally also carries a stamped grid, via a guide roller 108, is then guided by two pairs of rollers 109 and 110 in turn in a transport loop 75, and then rolled up on the roll 111. The first pair of rollers 109 is like this adjusted so that it only transports the web when the punching process is in progress, but not in the other periods, i. the braking force of the brush rollers 122 is just so large that the lead frame between the rollers 109 passes through or the rollers 109 do not rotate at all, as long as the transport of the web is not also from the Punching process is additionally supported. The two transport loops 75 are there necessary for the unwinding of the roller 66 and the reel on the roller 111 the Intermittent feeding process can not interfere. With advantage can also still Sensors 120 may be provided which detect the length of the transport loops and with whose signal is e.g. the input roller pairs 105 and the Ausgangsrollenpaare 110 controlled can be. Instead of the two pairs of rolls 109 and 110 and between them forming transport loop 75 could also be a highly sensitive, so-called Dancer system are used, as it is above the corresponding transport loop 75th or approximately also shown in FIG. 3 and designated there as a transport memory 36 or 37.

The aforementioned retraction rollers 123a and 123b, Fig. 15 in an enlarged view. she rotate the feed direction of the dispensing material laminate 20 respectively and point each on a circle segment of about 45 ° (corresponding to an arc length of, for example, about 50 mm) has a radial increase 124 a and 124 b, with which they with the Donation material laminate 20 come into contact. Only if and as long as both radial Elevations 124a and 124b are in contact with the donor material web 23 at the same time, this is clamped (clamping phase, angle β) and opposite to their feed direction a moved back a certain distance. By changing the relative rotational position of the two Retraction rollers 123a and 123b can be used to advantage the length of this step back change. Thus, e.g. the lower retraction roller 123b is synchronous in uniform rotation are added to the donation cylinder 13, while the upper retraction roller 123 a with a servo motor between two clamping phases in contrast somewhat accelerated or slowed down. As a control signal for this purpose, the measurement signal of an optical sensor 125 are used, which is arranged behind the cylinder pair 13, 28 and which resulting web widths detected.

Quite correspondingly, namely by at least one controlled back step controlling a Markeneinzugs works, but in this case the control signal bevozugt won with an optical sensor 126, which in front of the cylinder pair 13, 28 is arranged, because when punching the stamps are usually punched out with.

In the following we will return to forms with edge-free, integrated cards become. As described above, such forms or cards can be used in particular by donations and punching in the same operation (dispensing) with produce high precision. As already mentioned, such forms can be basically but also sequentially regarding the steps donations and punching produce, if only the Registration is sufficiently well controlled. A similar problem with the Incidentally, registering occurs when it comes to the donation and / or a Punching relative to an already existing on the print substrate, structured and possibly even to place an optically effective contrast line forming imprint as accurately as possible.

The register problems mentioned so far have led to more or less broad Overlap margins of at least 3 mm and more at least with respect to Donation material were provided. Using in particular the above Devices and methods, even if they are not directly the so-called. Spendestanzen However, it has been shown that these problems occur even at high Controlling processing speeds and economically at least so far Let that be a significant difference to the normal user of the forms a form produced by means of dispensing deashing is not readily apparent. Also when donation punching yes, if necessary, the problem remains a prior, structured imprint as accurately as possible, but this problem is possibly avoidable, a preprinted donor material is used. The tolerance limit, only below of which one is inclined to speak of a border-free map, is likely at about 1 mm lie. In general, however, efforts will be made to reduce the tolerances below one half a millimeter.

As far as in a sequential donations and punching and possibly also sequential attachment a contour-matched imprint with tolerances (for example of the order of a half Millimeters or less) are the following training or procedures prefers:

Applying the imprint (if provided) to the print substrate in the first step. thereupon is first punched in such a way that the punching line is pulled slightly tighter than the printed contrast line; this so that the detached card at its edge no stripes with e.g. receives a contrasting color. Only then donated, with the aufgespendete Part slightly smaller or larger, but preferably the same size as that of Stanzline framed area is selected.

If it is to be donated first and then punched, it is an advantage, the donation slightly smaller than the punching line to avoid, from the edge of the On narrow part, narrow strips (so-called angel hairs) are separated, the When using the forms for example in a printer problems could. If, however, for example, the map (defined by the punching line) with rounded corners and the attached part with sharp, overhanging corners Performs, this problem would be tolerable, provided that the edge separated strips with stay connected to the protruding corners.

Finally, it should be noted that as far as in the above description certain features or configurations related to and within the framework of specific embodiments are described, which should not mean that they are only so applicable. Rather, one skilled in the art will recognize that they are readily available and possibly with advantage in other of the described examples used or with these can be combined.
