• films or papers in various forms and designs, are often dispensed on endless webs or in holes in them.
• the labeling area in the area of form printing and in the Such integrated processes are becoming increasingly important in the production of integrated cards.

• WO 97/16370 (Hunkeler AG) are generally used to apply films or papers to an endless web or to print carrier sheets.
• the donation material is fed in the form of a web and cut to length between the donation cylinder and a counter cylinder equipped with a cross-cutting knife.
• the parts resting on the dispensing cylinder are then transferred to the printing medium as a result of the rotation of the dispensing cylinder and adhere to it via an adhesive layer.
• they are usually designed as suction cylinders.
• WO 97/16370 also mentions the holding of the parts to be dispensed on the dispensing cylinder by electrostatic forces.
• the print carriers must also be punched in the area of the cut, for example in the production of integrated cards. This usually takes place immediately after the application in a subsequent work step, whereby the comparison (register management) between these two work steps can be difficult, particularly in the case of fast productions.
• the area of the dispensed material is generously laid out overlapping the card to ensure that the card is always completely covered by the dispensing even in the event of relative shifts in the work steps.
• the invention is based inter alia on the task of providing a form with a removable and / or detachable card, which is improved in particular with regard to the visual appearance of the card.
• This object is achieved in the case of a form of the type mentioned at the outset in that the layer material essentially covers only the surface of the card and is arranged essentially in the same shape as the punched line of the card with respect to its outer edge.
• the layer material is therefore at least approximately delimited by the punching line of the card and there is no or no overlap of the dispensing beyond the punched card edge.
• the card can also be a so-called "butterfly card", which is characterized in that parts lying one above the other in the card are arranged side by side in or on the form.
• Another object of the invention is to provide an apparatus and a method which generally permits the simplified and more precise production of a print carrier which has been dispensed with a cut part of a donation material and optionally punched, but in particular also the production of a form according to the present invention ,
• This further object is achieved in a device and a method of the type mentioned at the outset in that the cutting edge is designed as a narrow punching ridge.
• Punching burrs are to be understood here to mean any type of cutting edge which is not designed in the form of cross-cutting knives embedded in the grooves of a cylinder. Using cutting edges designed as punch burrs instead of cross-cutting knives allows a significant increase in precision without any adjustment effort, especially with faster throughput speeds of the print carriers.
• the punch burrs directly on the surface of the cylinder (so-called rotary punching, cylinders, the cylinder surface of which is somewhat milled while leaving the burrs, ie the burrs are an integral part of the cylinder and cannot be adjusted in height and positioning) or preferably on one, on the surface of the cylinder in particular, magnetically adhering thin punched sheet, the dispensing process can be carried out at high speeds without the punch height or punch position often having to be readjusted. This also reduces the registration problems accordingly.
• the stamped burrs can be curved, and particularly preferably can be designed to form at least approximately self-contained lines.
• This design allows, for example, the punching out and dispensing of parts whose outer edges have any shape.
• a preferred embodiment is characterized in that the donation material, respectively. the parts are punched and / or punched out between the dispensing cylinder and counter cylinder and that the parts are then conveyed onto or into the printing medium by rotating the dispensing cylinder.
• the cutting edges required for punching can be arranged either on the dispensing cylinder or on the counter cylinder. It can also be provided that the printing medium is guided between the dispensing cylinder and a further counter cylinder and is punched there from above or below using at least one cutting edge formed on one of the two cylinders.
• Cutting edges can thus be arranged on each of the three cylinders mentioned, and cutting edges can also be present on a plurality of cylinders, so that the parts and / or the pressure carrier can be stamped and / or punched out from different sides along different contours.
• Such an arrangement is extremely flexible and allows the application of extremely versatile shaped and die-cut parts.
• cutting edges are provided on the dispensing cylinder and both a counter cylinder and a further counter cylinder of the type mentioned are also present, there is the particular advantage that with these cutting edges both in the gap between the dispensing cylinder and the counter cylinder and in the gap between the dispensing cylinder and the other counter cylinder can be punched. These cutting edges can therefore be used in the gap between the dispensing cylinder and the counter cylinder, e.g.
• a part is punched out or punched out of a dispensing material, this is subsequently conveyed by the rotation of the dispensing cylinder and embedded in the cutting edges onto or into the printing medium and the printing medium in the gap between the dispensing cylinder and the other counter cylinder is also the same as the contour of this part of be punched on the donation side.

• the combined dispensing and punching of the print carrier in this way is also referred to below as "dispensing punching". Any donations already on one or both sides of the print carrier can also be punched during this process.
• a further embodiment is characterized in that at least one, but particularly preferably all of the cylinders are magnetic cylinders, that the stamping burrs are designed as stamping plates, which stamping plates are a base plate resting on the cylinder surface of the cylinder and at least one is essentially perpendicular to the base plate and with respect to the Include axis of the dispensing cylinder radially outwardly extending cutting line, and that the stamping plates are adhered to the magnetic cylinders by magnetic interaction.
• Such burrs allow the parts to be cut quickly and extremely flexibly, while at the same time requiring little adjustment of the machine.
• Another embodiment of the invention is characterized in that the dispensing cylinders are designed as suction cylinders and that the adhesion of the parts is effected during the rotation of the dispensing cylinder. It is also possible to fix the parts electrostatically to the dispensing cylinder.
• the cylinder surface of the dispensing cylinder is preferably electrostatically polarized in the direction of rotation of the dispensing cylinder substantially immediately before the parts are detected by a first sword electrode. It can also prove to be advantageous if a first sword electrode advances the dispensing material immediately before cutting Cutting agent is electrostatically polarized from the side of the self-adhesive layer. Or else the cylinder surface of the dispensing cylinder and the parts lying thereon in the direction of rotation of the dispensing cylinder can be electrostatically polarized essentially immediately after the parts have been gripped by a second sword electrode.
• An additional embodiment is characterized in that the punching plate has bores which are at least partially arranged over suction holes in a suction cylinder and which allow the formation of a negative pressure, the bores particularly preferably being arranged essentially directly in the direction of rotation of the dispensing cylinder behind a front cutting line and which furthermore preferably have a distance between the bore centers which is more than twice as large as the diameter of the bore.
• the dispensing part is captured by the dispensing cylinder immediately at the start of the punching process, and the spacing also allows any distance between the lateral cutting lines without the suction holes of the suction cylinder coming under the lateral cutting lines and thereby deforming them.
• the sheet is magnetically fixed to the dispensing cylinder, as is still preferred, and if the absorbent property of the dispensing cylinder, which is designed as a magnetic suction cylinder, is only used to hold the dispensing parts, there is the further advantage that the sheet does not fall off the roll when the suction pump is switched off.
• a further embodiment is characterized in that the dispensing material is at least partially coated with a self-adhesive layer on the lower side facing away from the dispensing cylinder, so that the parts remain adhering to the printing medium due to the adhesive effect of the self-adhesive layer.
• the dispensing material supplied as a web can be covered with a covering material on its side provided with the self-adhesive layer, this covering material can be provided with a separating layer on its side facing the self-adhesive layer, and the covering material together with the separating layer before or essentially during or else can be removed and removed from the self-adhesive layer of the donor web even after cutting.
• donation material can be easily supplied in roll form and dispensed with little technical effort, ie without in-line gluing or similar processes.
• the donation material can also be fed intermittently, the donation material essentially only then is transported when the first funds are about to cut a part and the part is captured by the donation cylinder.
• a backward step can also be installed, in which the web of donation material is transported somewhat backwards in the period in which no punching is carried out. In this way, the formation of unnecessarily much waste while at the same time simply dispensing can be avoided.
• the regression method can also be used in general to increase the positioning accuracy of the donated goods.
• the form according to the invention stands out as stated above; by the fact that the layer material essentially covers only the surface of the card and is arranged with its outer edge essentially in the same shape as the punched line of the card, i.e. that there is no or at least substantially no overlap of the dispensing beyond the punched card edge.
• a form can be produced in a particularly simple manner using one of the devices or a method described above, since these allow the die-cutting and dispensing to be carried out precisely.

• FIG. 1 shows a simple schematic representation of a dispensing mechanism, in which parts 12 are gripped by a dispensing cylinder 13, here designed as a suction cylinder, cut to length by cutting lines 25b fixed on or in the dispensing cylinder 13, and then dispensed onto an endless web 15.

• the dispensing material 23 can be film, paper, or even a multi-layer laminate made of a wide variety of materials. It is of course also possible to supply the donation material in a non-glued form and to some extent to carry out an in-line gluing. However, it has proven to be much easier for a large number of producers to simply supply the donation material from a roll as a glued donation material web and to have the rolls delivered by a company that specializes in coating with self-adhesive.
• the covering material 24 is separated and removed via suitable rollers 19.
• the remaining donation material 23 is then guided with its unglued side facing the donation cylinder 13 into the gap between the donation cylinder 13 and a counter cylinder 10.
• the counter cylinder 10 can be provided with counter plates 11 in regions in the zones against which the cutting lines 25b attached to the dispensing cylinder 13 come to rest when the two cylinders rotate.
• the parts 12 are thus separated between the counter cylinder 10 and the dispensing cylinder 13 by the cutting lines 25b, which can be designed all around or as cross cutters. Any lead frame 26 that may arise can be easily removed behind the gap.
• the supply of the dispensing material web 23 can also be designed intermittently, for example by only advancing when the cutting lines 25b are about to be cut.
• the suction cylinder 13 which co-rotates with the fed continuous web 15 at least at the moment of dispensing, transports the parts 12 through its rotation onto the endless web, the parts 12 sticking to the cylinder 13 during the rotation due to the suction vacuum.
• the suction cylinder 13 should advantageously be set such that the suction effect is briefly interrupted in the area of dispensing, in order to ensure that the parts 12 do not stick to the cylinder 13 after contact with the endless web 15.
• the continuous web 15 is also punched or punched out simultaneously with the punching line 25b.
• cutting cylinders are usually used for cutting parts to length, in which knives are embedded in knife grooves. According to the prior art, it is not the dispensing cylinder that acts as the cutting cylinder, but rather the counter cylinder located at the top, ie the attachment of the cutting means is interchanged.
• such cutting cylinders have a number of disadvantages for the task described in this exemplary embodiment, in which the cutting cylinders are also intended to be dispensing cylinders at the same time: the height-adjustable knives often have to be readjusted. For example, readjusting the knives in the grooves is necessary if the speed of the process is changed, but also if the dispensing material 23 changes in thickness or composition.
• knives can only be arranged where there are grooves in the cutting cylinders, which limits the setting of the cutting to length.
• the throughput speed of such cutting cylinders is quite limited, which has a limiting effect in connection with the exemplary embodiment outlined in FIG. 2, because higher throughput speeds would actually be possible with electrostatic adhesion of the parts 12 to the dispensing cylinder.
• stamping plates 25 consist of a base plate 25a, which adapts to the cylindrical surface in its rounding, and which rests on the cylinder surface, so that good magnetic adhesion of the stamping plate 25 to the magnetic cylinder 13 is possible, and a cutting line 25b running thereon.
• a stamped sheet 25 is usually produced by etching a sheet of, for example, approximately 0.5 mm thick, leaving out the cutting line 25b, to a thickness of, for example, approximately 0.1 mm.

• Such punched sheets are used in label technology for punching labels, but only under conditions in which the material to be cut and the magnetic cylinder rotate at the same speed, so that the punched sheets 25 can hardly move on the magnetic cylinder.
• pre-processing and subsequent application are fundamentally different. In a first step, a donor material laminate is printed and punched out, so to speak, off-line, with only the labels remaining on the cover material, but the leadframe being removed. In a next step, the labels adhering to the cover material are passed over a sword, separated from the cover material and dispensed.
• a roller made of porous foam can preferably also be provided.

It is important that only the cutting lines 25b, but not the base plates 25a, come into contact with the foam roller, since otherwise the parts 12 may be provided with silicone oil, which can interfere with the subsequent processing.
• magnetic cylinders 13 are stable regardless of speed and material and no readjustment is necessary. In this application, they can be used both as suction cylinders and in electrostatic fixing technology. In addition, high speeds can be achieved with magnetic cylinders without any problems, so the cutting process is no longer speed-determining. While cross-cutting knives according to the prior art are usually not able to cut thick materials of more than 0.1 mm at high speeds (a problem that occurs particularly with polyester films), punched sheets 25 can also be used without problems with thicknesses of up to 0.2 mm become.
• punched sheets 25 of the type described Another particular advantage of using punched sheets 25 of the type described is that any punching shapes can be implemented in a simple manner because the lines of the cutting lines on the punched sheets can of course be freely selected.

• FIG. 5 shows dispensing mechanisms in which the covering material 24 is only removed after the parts 12 have been cut to size, and in this respect the aforementioned problem and the need to equip device elements with adhesive surfaces are avoided from the outset. In this case, however, it must be ensured, if necessary by additional measures, that the parts 12 to be dispensed can be removed safely and easily from the covering material 24 and from any lead frame 26 after being cut to be able to be taken over by the dispensing cylinder. As such an additional measure, the donor material laminate is temporarily pre-separated in the example of FIG. 5 in order to reduce the adhesion between its layers before cutting. In FIG.
• the donor material laminate 23 is first rolled off a roll 66 in a supply loop 75, then is gripped by two feed rolls 72.
• the covering material web 24 is now separated from the dispensing material web 23 and only returned to the dispensing material shortly before or in the gap between the counter cylinder and the dispensing cylinder under the influence of a first air nozzle 69.
• the covering material web 24 is pulled off directly behind the gap under the influence of a second air nozzle 70 and the part 12 is transported from the dispensing cylinder onto the web 15.
• the adhesion to the donation cylinder is again effected by means of electrostatic adhesion.
• a dielectric film 76 can be inserted between the cutting lines 25b, as indicated in FIG. 5b).
• the mechanism in FIG. 5c) does not require a pre-separation.
• a separating lip 82 is arranged here directly behind the gap, which guides the covering material 24 around a sharp edge, so that the parts 12 can be removed more easily.
• this underside of the separating lip is also provided with a soft, brush-like or fur-like coating, by means of which the punched-out parts 12 are held in contact with the dispensing cylinder, but which coating, on the other hand, can avoid the stamping plate 25 and its cutting lines.
• a so-called air brush 81 can be used to support the detachment of the parts 12.
• the air brush 81 is designed as a roller, the axis of which runs parallel to the axes of the cylinders and extends at least across the width of the parts 12.
• the high-speed (up to approx. 5000 rpm) roller is covered with bristles made of preferably adhesive-repellent material, such as nylon, Teflon or coated metal.
• a brush housing 83 is also arranged on the side facing away from the gap.
• the channeling effect of this brush housing 83 when rotating in the same direction, leads to the rotation of the cylinder 28 to form an air jet, which supports the detachment of the parts 12 from the covering material 24.
• a separating roller can also be used at the corresponding point, e.g. has a diameter of 12 mm and e.g. is built up from a shaft with a diameter of 10 mm with slide bushes with a wall thickness of 1 mm each. This separation roller is then adjusted as close as possible to the punching plate and avoids the friction of a separation blade.
• an endless web is not fed, but instead, according to the prior art, paper sheets are continuously removed from a sheet stack 84, processed, and then deposited in another sheet stack 85.
• the individual sheets are guided between the two stacks 84 and 85 by two tractors 73.1 and 73. 2, the first tractor 73.1 transferring the sheets seamlessly to the second tractor 73.2 in such a way that the sheets, when removed from the second tractor 73.2. are also kept for a short time by the first tractor, so that they are always clearly guided and are never loose.
• the dispensing cylinder 29 and the pressure roller 16 do not have a guiding or transport function here, which goes beyond the taking of the sheets through the punching plate, in particular in the presence of transverse cutting lines.
• the single sheet transport device is also functional and can be used if a simultaneous punching together with a dispensing process should be avoided in individual cases.
• An alternative support for the detachment of the covering material 24 is shown in FIG. 5d).
• the material is first guided along the cylinder 29 and then around a separating lip with a much higher deflection angle (up to 180 °).
• this arrangement has a possibly better separation characteristic than the above;
• a backward step suitably carried out with the dispensing material web between two feeding steps.
• FIG. 6 shows a preferred embodiment of the cutting lines 25b of punched sheets 25, which is able to prevent self-adhesive 60 from flowing out after the laminate has been applied to the continuous web.
• 6a) shows the conditions in the gap between counter cylinder 28 and dispensing cylinder 29, FIG. 6b) those during the dispensing onto the pressure carrier 15. This is done in such a way that the inner edges of the cutting plate are made perpendicular to the base plate 25a and only the outer edges are chamfered. In this way, the side edges of part 12 also become vertical and the superficial presence of self-adhesive which occurs in the case of oblique edges is thus avoided.
• FIG. 7 shows the analog gap ratios and the punching plates 25 (here also with back pressure lines 25c) in the case of a window covering as has already been described in detail in FIG. 4.
• FIG. 8 describes the conditions in the case of a punching dispensing from above and a punching from below.
• the lower dispenser 33 has already been dispensed before the upper film is dispensed, and the two die cuts are congruent, leaving a residual thickness for holding the die cut in the print carrier 15.
• FIG. 9 describes the gap ratios in the case of a dispensing according to FIG. 2.
• a multi-layer carrier material 33 is previously applied from the lower side, punched and dispensed only from above.
• the carrier material 33 can be, for example, a material as described in EP 836953 and as is used in the production of cards integrated in forms
• the method described can also be used if the parts 12 are not cut or cut to size by the dispensing cylinder 29, but also if the parts 12 are supplied, for example, in the form of a label or another form already cut.
• the parts 12 fed in a cut form for example on a cover material web 24, can, as schematically illustrated in FIG. 10, be peeled off from the cover web 24 via a separating lip 82.
• the parts 12 are inserted into the punching plate 25 arranged on the dispensing cylinder 29 and then dispensed from the cylinder 29 by punching the endless web 15 onto the same.
• a method proves to be relatively uncomplicated, in particular if the parts 12 are automatically captured to a certain extent with a circumferential cutting line of the punching sheet and thus adjusted.
• the so-called gap dimension i.e. the shortest distance between the individual rollers should preferably be adjustable in order to process different material thicknesses with regard to the print carrier and / or the dispensing material and of course also to be able to adjust the punching depths desired in each case.
• the middle roller in Fig. 1 the dispensing cylinder 13
• the middle roller is preferably mounted stationary and this opposite the two outer rollers (in Fig. 1 the counter cylinder 10 and the pressure roller 16) Eccentrically adjustable.
• FIG. 11 a shows a perspective view of a section through a form with an integrated card, in which the card dispenser 12 on the top is designed to have the same contour as the outer line of the card. On the underside there is an overlap of a carrier material to keep the punched card in the form. It is easy to see how the shape-matched dispensing leads to a visually and tactile appealing and intuitive product, which usually does not require further identification of the card outline and removal aids.
• FIG. 11 b) shows the corresponding view of an integrated card donated on both sides, as can be produced, for example, with a device according to FIG. 3 and similar to FIG. 8.
• the map is identical in shape to the final map in both sides Form designed and is held in the form by a residual thickness left at die cuts 41 and 42.
• FIG. 12 a shows a form with an integrated butterfly card, in which a laminate designed with the same contour as the outer line of the unfolded card is dispensed from one side. Again, this results in an optically and tactile extremely pleasant and intuitive product, since there are no overlapping donations.
• the laminate is provided with a self-adhesive layer 60 on its side facing the form, and can therefore be used directly from the roll, e.g. after covering a covering material applied thereon are fed in as punching material, punched and dispensed.
• a film layer 62 is arranged above the self-adhesive layer 60, which in turn is provided on the upper side with a siliconization 61. On top of this siliconization there is in turn a self-adhesive layer 60 and a film layer 62 that closes on the top side, optionally printable or already printed. If the dispensing laminate is to be supplied from a roll without covering material, the film layer 62 on the top side can also be treated or coated in such a way that the laminate is on itself can be wound up.
• the dispensed part 12 is now punched from the upper side along the line to be folded between the two parts lying next to one another in the form with a perforation punch 87 up to the height of the siliconization 61, and from the bottom side along the dotted line (punch 34) to punched in at the height of the upper self-adhesive layer 60.
• the two parts lying next to one another can preferably be removed from the form on the right, the left part and the onion ring on the left between the siliconization 61 and the upper self-adhesive layer 60 16st, and the coupon 15.1 on the right being detached from the form.
• FIG. 12 c) shows an exemplary embodiment of a butterfly card stamped with the same contour and with the same laminate as in FIG. 12 a), but in which there is no onion ring.
• the punching must be carried out differently. Essentially congruent with the perforation punch 87, a punch is made from below between the two parts up to a maximum of the surface of the upper self-adhesive layer 60.
• FIG. 12e A very simple variant of an integrated, contour-locking butterfly card is outlined in FIG. 12e).
• a simple laminate consisting of a self-adhesive layer 60 and a film layer 62 is dispensed.
• the print carrier 15 In order to keep the left part of the card detachable, however, the print carrier 15 must be provided with a siliconization 93 in this area before it is applied. The punching is carried out according to FIG. 12c), and again a card 88 is created around a coupon 15.1 after removal and folding.
• the stamping plate has bores 100 which are provided to hold the stamped part 12 on the dispensing cylinder 13.
• the stamping plate 25 rests on a suction cylinder 13 which has suction bores 102.
• the plate 25 can either be held on the cylinder 13 by further suction bores, not shown in the figure for the sake of simplicity, or the suction cylinder 13 can at the same time be designed as a magnetic cylinder.
• Magnetic cylinders usually have a structure that also enables suction bores 102 to be made subsequently: the magnetic material elements are usually embedded in segments and in rows parallel to the axis of the cylinder in the cylinder jacket of a full cylinder.
• non-magnetic strips of the solid cylinder material which are wide enough to make suction bores 102, usually remain on the surface of the cylinder without having to drill the mostly brittle magnetic material.
• the combination of a magnetic suction cylinder, the absorbent property is used essentially only for adhesion of the diecut 12, and its magnetic property is used to hold the sheet 25 on the cylinder surface has the advantage, among other things, that the punched sheet 25 still when the vacuum pump, which generates the negative pressure, is still switched off sticks to the cylinder 13.
• the punching plate 25 has a base plate 25a on which a cutting line 25b is arranged. Viewed in the direction of rotation 101 of the dispensing cylinder 13, there is thus a front cutting edge 25b1, which acts first on the dispensing material 23 during the punching process, a rear cutting edge 25b2, which only engages at the end when the punched part is almost completely cut out, and lateral cutting edges 25b3 and 25b4. It has proven to be particularly advantageous to arrange the bores 100 in a row as close as possible immediately behind the front cutting edge 25b1, since the punched part 12 is then immediately caught by the negative pressure at the start of the punching process and is very efficiently detached from any covering material which may be present can. The time-consuming pre-separation of dispensing material and cover material before punching between dispensing cylinder 13 and counter cylinder 28 is then unnecessary.
• the stamping plate 25 should of course be arranged on the dispensing cylinder in such a way that the suction holes 102 and the bores 100 lie one above the other.
• the two bores 100 and 102 also have the same diameter d with the same spacing D, or else the bores 100 are smaller than the suction bores 102.
• the suction cylinder does not have individual bores, but rather suction slots arranged parallel to the cylinder axis , If a suction hole 102 of the cylinder 13 comes immediately below the cutting line 25b3 or 25b4, this can lead to an irregularity in the cutting height of the cutting line and negatively influence the punching (a typical sheet has a base thickness of approx.
• FIG. 14 shows a device in which the donor material laminate 20 is transported intermittently and in which a withdrawal or regression of the donor material laminate can be carried out in a controlled manner between two feed steps in each case.
• the withdrawal or regression serves to further minimize the waste on the donor material web 23, which is caused by the unused areas (webs) between two diecuts.
• Another function is to control brand entry. This is about positioning a branded donation as precisely as possible on a print carrier.
• the dispensing material 20 in the device of FIG. 14 is gripped and transported by a roller 66 by a driven guide roller pair 105. Behind it is a supply loop 75 of material 23, which is terminated by a pair of standing brush rollers 122.
• the brush rollers 122 are pressed against one another and bring about a slight braking of the dispensing material laminate. The braking force is dimensioned so that it only allows further transport when a punching process is in progress. This results in an intermittent feed.
• the brush rollers 122 are followed by a pair of retraction rollers 123a, b, the design and function of which will be described specifically.
• a guide roller 107 which guides the web 23 at a certain angle ⁇ between the dispensing cylinder 13 and the counter cylinder 28, where it is punched.
• the guide roller 107 can be used to influence how long the negative pressure can be built up through the bores 100, for example when using a punched sheet according to FIG. 13. If the angle ⁇ is set small, the web 20 runs tangentially with the dispensing cylinder 13 for a little longer and there is more time to build up negative pressure. Behind the pair of cylinders 13 and 28, the punched laminate is first passed over a separating roller 121 to separate the parts to be dispensed, as has already been described above in connection with FIG. 5.
• the remaining covering material which possibly also carries a lead frame, runs over a deflection roller 108, is then guided in turn into a transport loop 75 by two pairs of rollers 109 and 110, and then rolled up on roll 111.
• the first pair of rollers 109 is set so that it only transports the web when the punching process is in progress, but not in the other periods, i.e. the braking force of the brush rollers 122 is just so great that the lead frame grinds between the rollers 109 or the rollers 109 do not rotate at all, as long as the transport of the web is not additionally supported by the punching process.
• the two transport loops 75 are necessary so that the unwinding from the roll 66 and the winding onto the roll 11 1 cannot interfere with the intermittent feeding process.
• sensors 120 can also be provided, which detect the length of the transport loops and with whose signal, for example, the input roller pairs 105 or the output roller pairs 110 can be controlled.
• a highly sensitive, so-called dancer system could also be used, as is shown above the corresponding transport loop 75 or, for example, also in FIG. 3 and is referred to there as transport storage device 36 and 37, respectively ,
• the above-mentioned retraction rollers 123a and 123b are shown in an enlarged view in FIG. 15. They each turn against the direction of advance of the dispensing material laminate 20 and each have a radial elevation 124a or 124b on a circle segment of approximately 45 ° (corresponding to an arc length of, for example, approximately 50 mm), with which they come into contact with the dispensing material laminate 20 , Only if and as long as both radial elevations 124a and 124b are in contact with the dispensing material web 23 at the same time, is it clamped (clamping phase, angle ⁇ ) and is moved back a certain distance against its direction of advance.
• the length of this backward step can advantageously be changed.
• the lower retraction roller 123b is set in uniform rotation synchronously with the dispensing cylinder 13, while the upper retraction roller 123a, on the other hand, is somewhat accelerated or braked between two clamping phases.
• the measurement signal of an optical sensor 125 which is arranged behind the pair of cylinders 13, 28 and detects the resulting web widths, can be used as the control signal for this.
• control of a brand retraction works in a corresponding manner, namely by means of at least one stepped back step, but in this case the control signal is preferably obtained with an optical sensor 126, which is arranged in front of the cylinder pair 13, 28, because the stamps are usually stamped out with the punching.
• the following designs or procedures are preferred: Applying the print (if provided) to the print carrier in the first step. Then the punching is first carried out in such a way that the punching line is drawn a little tighter than the printed contrast line; This is so that the removed card does not receive any stripes with, for example, a contrasting color on its edge. Only then is it dispensed, the part dispensed being chosen to be slightly smaller or larger, but preferably the same size as the area framed by the punching line.
• the donated item slightly smaller than the punching line to prevent narrow strips (so-called angel hair) from the edge of the dispensed part from being cut off, which, for example, when using the forms in a printer could cause problems.
• the card defined by the punched line
• this problem would also be tolerable, provided that the strips separated on the edge remain connected to the protruding corners.
