is operable and / or operated in two different operating modes. This is done in dependence on the incoming arch B, provided transport destination. In the first operating mode m1, z. As a storage mode m1, in which one or more sheets B from the first stack 1 1, z. B. Makulaturstapel are 1 1, to store the rotational speed of the drive 106 changes depending abzulegendem _β sheet at least once ν from a first velocity, _η effecting speed which z. B. as the speed of the incoming sheet substantially - ie with a maximum deviation of ± 10% - the above-mentioned conveying speed v32 corresponds to one of the

Storage speed v _from effective speed and back to essentially conveyor speed v32. If several successive sheets B _n sequentially store, so that this first operational mode m1 repeated as often as necessary so that the brake means 48, 49, that is to be deposited, the holding means 92, the speed v92 between conveying speed v32 v on depositing speed _from and back in time to the incoming and Sheet B _n changes.

When changing to storage speed v _ab , the speed v92 of the

Holding means 92 during the active contact with the conveyed sheet B preferably lowered to a speed v _from the z. B. at most 50%, advantageously less than 20%, preferably less than 10% of the conveying speed v32. Essentially the conveying speed v32 corresponding higher speed v92 of

Holding means 92 is in stationary operating situation about z. B. at least 4 m / s, for example in the range of 4 to 9 m / s, in particular in the range of 5 to 8 m / s. In contrast, the storage speed v _from z. B. at most 2 m / s, for example in the range of 0.5 to 2 m / s, in particular in the range of 0.7 to 1, 4 m / s.

The deceleration, ie the lowering of the speed v92 of the holding means 92 from the speed v92 corresponding to the conveying speed v32 to the depositing speed v _ab, takes place, for example, in the sheet path s only in a phase in which the front edge 109 of the sheet B to be deposited is _{n + 1} ; B _P only less than half an arc length from the escape s2 to the downstream stack trailing edge and the leading edge 1 1 1 of the sheet to be deposited B _{n + 1} ; B _P only less than half Arc length from the escape s1 to the upstream stack leading edge is removed.

In the second operating mode m2, z. B. a guide mode m2, in which one or more sheets B on the first stack 1 1, z. B. waste stack 1 1, or the

Dispensing stations I are to be carried away, the drive 106 over at least the entire phase of the contact between the braking device 48, 49, d. H. the holding means 92, and operated over the stack 1 1 and the dispensing station I wegzuführendem sheet B at a speed which at the holding means 92 a substantially the

Conveying speed v32 causes corresponding speed v92. If there is a constant conveying speed v32, this is likewise at least during o. G. Contact phase constant. This second operating mode m2 is basically independent of the presence or the specific embodiment of a first operating mode, but is of particular advantage in connection with an embodiment of a first operating mode set forth here.

In a preferred embodiment of the braking device 48; 49 are over appropriate

Switching means 107 clocked activatable and deactivatable retaining means 92 are provided. For clocking the switching means 107 is available, for example, with control means S107 in

Signal connection, which is designed and arranged to activate and deactivate the holding means 92 synchronized and / or to effect a correlation to a machine and / or printing material phase position Φ. In the case of two operating modes m1; m2, these differ, for example, not only in the phase-related velocity profile, but also in the switching profile for the wiring, d. H. Activation and deactivation of the holding means 92.

In the first operating mode m1, the holding means 92 is deactivated in the entire or at least part of the positive acceleration phase from the depositing speed v _down to the conveying speed v32. In the embodiment as suction elements 92 in this phase at least temporarily set the suction, ie the application of a Vacuum p ^" on the suction element 92 interrupted.

In the second operating mode m2, the activation of the holding means 92 over at least the entire phase of the contact between the braking device 48, 49, d. H. the

Holding means 92, and maintained over the stack 1 1 and the dispensing station I wegzuführendem sheet B. Preferably, the suction or the negative pressure p- remains maintained over the entire cycle. In the embodiment as suction elements 92, in at least this contact phase the suction remains switched on, ie the vacuum p ^{"is maintained} on the suction element 92. Preferably, the suction or the vacuum p ^" remains over the entire cycle from the entry of the sheet B _n to be transferred into the Area of the braking device 48; 49, in particular in the effective range of

Holding means 92, until the next sheet B _{n + 1} enters the area of the braking device 48; 49, in particular in the effective range of the holding means 92, turned on. Are several consecutive sheets B _{n + 1} ; B _{n + 2 can be} successively transferred, the suction or the negative pressure p ^" remain switched on over the duration of the relevant cycles.

By sucking over the entire cycle, in particular over the cycles of several sheets to be transferred, it is ensured that the sheet in the second

Operating mode m2, ie the guide mode m2, the sheet to be transferred B _{n + 1} detected and spans substantially without relative movement over the stack to be transferred 1 1, 12. This prevents or at least reduces a "break-in" of the sheet B _{n + 1} to be transferred into the storage chute of the stack 1 1 to be transferred, which allows transfer without sacrificing quality, which is particularly relevant for high-speed productions.

A suction air permanently switched on in the second operating mode m2 favors the earliest possible starting and holding of the trailing edge of the sheet B. For the two operating modes m1; m2 are, for example, in the control means S48; S49 two mutually different provisions for the generation of set values for the speed v92 of the holding means 92 held. The regulations include, for example, a dependency on the conveying speed v32 and can also be dependent on further influencing variables and by operating personnel

be parameterizable.

The regulations include each different

ToOrdnungsvorschriften between the current conveyor speed v32 and a setpoint or setpoint curve for the speed v92 of the holding means 92. For the ZuOrdnungsvorschrift the second mode of operation m2 is at least for the duration of contact with the sheet B a proportional to the conveying speed v32 correlated course of the holding means speed v92 and for the

For regulation of the first operating mode m1 within at least part of the duration of the contact with the sheet B at least one ramp with a relative to the conveying speed v32 sloping course of the holding means speed v92 provided.

B. by the correspondingly high-carrying support 36; 37 itself arranged on this sheet guide means, for. B. baffle is formed. For example, for the second operating mode in the dispensing station I in question, the carrying device 36; 37 by vertically positioning in a transport path near, z. B. the highest possible, location spent. In addition to this, before, during or after reaching this position, a named sheet guiding means can be set up or inserted.

As already indicated, the starting section 78 in the region of its upstream end has a run-on slope, preferably with a rounded edge 84, in particular upper edge 84. For this purpose, the conveyor system 21 facing, essentially flat guide surface 79 of the starting section 78 is in a downwardly bent, z. B. rounded starting surface 81 continues. Under the substantially flat guide surface 79 should be next to actually flat surfaces and slightly curved surfaces with a radius of curvature of z. B. throughout at least 1 000 mm, in particular at least 3000 mm, to be understood. The rounding of the edge 84 is z. B. in such a way that the edge 84 is rounded in such a way that a running in the transport direction vertical section considered course of the top between a first, lying in the region of the still flat or slightly inclined guide surface 79 point to a second point at which an inclination of the tangent to that at the first position is 45 °, at least a radius of 50 mm and / or that a course of the edge 84 between the end of the flat or at least substantially planar guide surface 79 and a perpendicular to the course of this plane calculated by 50 mm spaced point in the contact surface 81 at each point one

Radius of curvature of at least 5 mm, preferably of at least 10 mm, and preferably a maximum radius of curvature of z. B. 500 mm, in particular 200 mm. The radius of curvature here must not be constant in the considered section but can vary. An optionally mentioned rounded start-up surface 81 comprising legs can basically in the transverse direction, d. H. in the direction of the width of the delivery device, be continuous, partially interrupted or designed in several parts (see, for example, Fig. 8). The expression of the "plane guide surface" is intended to include below the above case of a slightly curved surface.

As "edge" 84 of the starting section 78 in the above sense, the upper corner region of the starting section 78 should be understood here, regardless of whether it is formed, for example, by the rounded corner of a solid component or, for example, by a bent-down metal sheet.

Preferably, in or before the vertical alignment of the contact surface 79 and below the given by the guide surface 79 height stop means 81 a

Anchoring device provided which for the in the first dispensing station I

to be deposited bow B limit the movement in the transport direction T. At these abutment means 82, the downstream stacking edge of the stack to be formed 1 1 is formed. In addition, movable stop means 83 may be provided, which by a drive means 64 with at least one drive means 99 in a first, z. B. active operating state beyond the given by the guide surface 79 height and in a second, z. B. inactive operating state below this level are arranged. In a little elaborate execution, several of the

Stop means 83 may be moved or moved together, for example via a connection or shaft. The starting section 78 can in the region of its guide surface 79 and / or in the region of its contact surface 81 and / or in the region of its rounded edge 84 air passage openings 68; 69, in particular blowing air openings 69 or

blown air passage openings 69, have.

In a first preferred embodiment of the starting section 78, this comprises in the region of the rounded edge 84, d. H. in an upstream of the planar guide surface 79 subsequent curved surface portion 84, a

Blowing device with one or preferably a plurality of blown air openings 97. Die

Blasluftöffnungen 97 may be formed by round or preferably slot-shaped recesses 97 in a rounded edge 84 forming material portion 84, in particular sheet metal portion 84 and from the inside of the start-up section 78 ago, d. H. from the side of the material section 84 facing away from the printing material transport, be supplied with blast air. The blast air supply can be formed by an air box which adjoins the material section 84 on the inside.

In a preferred embodiment, the blast air supply is formed by a blowing air line 98 running on the inside of the material section in the transverse direction, the wall of which in turn comprises outlet openings arranged corresponding to the blown air openings 97. The blast air line 98 is preferably formed at least in the region of its side facing the material portion 84 with a corresponding to the inside of the material portion shape. For example, the blast air duct 98 is a blower tube having a circular outer peripheral cross section and the material portion 84 is at least in the region of its blast air duct 97

opposite section in cross-section circular arc. The blast air openings 97 provided in the material section 84 have, at least in a printing material sheet guided in the direction of movement over the starting section 84 extending direction on the opposite to the outlet openings larger opening cross section. This ensures, for example, a secure passage of air.

In a particularly advantageous development, the preferably tube-like blown air line 98 can be mounted pivotably about an axis extending in the transverse direction. This makes it possible to adjust the position of the blown air outlet along the sheet movement direction at least slightly, in particular with respect to the outlet openings in the above-described larger blown air openings 97.

The starting section 78 designed in this way can in principle be used independently of the design of the dispensing device 03 with a plurality of dispensing station I; II be provided in the region of a beginning of a sheet guiding elements comprehensive conveyor line.

However, this is preferably at the beginning of a between two dispensing stations I; II arranged conveyor line provided.

Conventionally, the sheet B, guided only at the front edge by the conveyor system 21 or the holding device 32, in particular the holding elements 56, sinks into the shaft of the overrun dispensing station I; II until it is in equilibrium with the forming at the bottom of natural air cushion. The continuation of the bowing on predominantly horizontal guideway can be crossed at the end of the

Dispensing station I; II - especially in certain operating situations with, for example, low stack level .- lead to a harmful level jump. In this case, the natural air cushion can not, the sheet B as a wing over this stage on the following sheet guide 47.5; 78, in particular run-up plate 78 to lift. Especially at higher speeds, it may come to a striking contact with damaging contact on the underside of the arc B.

The possible effects may be due to one or more of the aforementioned

Measures (rounding and / or blast air) avoided or at least mitigated become. Instead of or in addition to one or more of the named

Measures is in a particularly advantageous embodiment of the delivery device 03 and / or the sheet guiding device 47 and / or of a dispensing station I; II directly downstream sheet guiding element 47.5; 78, in particular one of a

Sheet guide 47.5 included or this upstream start-up section 78, this or this or at least the guided bow B facing

Guide surface 79 formed with at least its upstream end in the vertical position variable and / or stored. In particular, this sheet guiding element 47.5; 78 or this start-up section 78 by means of a controllable drive means 283 made variable in its vertical position.

At least the upstream end of the starting portion 78 is in height to the variable stacking level, d. H. the height of the uppermost sheet B in the stack 1 1; 12, adjustable. Preferably, this end - in particular via control means - automatically adjustable in height to the variable stack level. For this purpose, the drive means 283 comprised by the actuator, in particular its control unit or drive controller, is in signal connection to a vertical position of at least the end of the

Sheet guiding element 78 in dependence and / or correlates to the stack level adjusting control means.

The placement or the variation takes place at least within an operationally provided adjustment range, which extends from an upper layer L ₀ , in the continuous printing in already partially formed stack 1 1; 12 of a minimum height without further

Height variation of the starting section 78 is stored to reach the finish stack height, down to a lower layer Lu, in which z. B. is stored in production at the beginning of stacking (see, for example, Fig. 9a) and c). The latter is approached, for example, when the time of the process of the stacking table 36; 37 should be used at least in part until reaching the working height assumed above for the printing and / or if at the beginning of stacking the working height, ie that in the above-mentioned Continuing pressure level of the top sheet layer to be ideally taken, due to a limited travel for the stacking table 36; 37 is not accessible with low stack heights. The between these two layers L ₀ ; Although Lu located layers L _z (.. See, e.g., Fig 9b) can in principle be approached stationary in other specific operating situations or can be, or are, however, regularly on the way between the other two layers L _0; Only pass through dynamically. Of the

operatively provided adjustment range between the upper and lower layer L ₀ ; For example, Lu amounts to at least 50 mm, preferably more than 100 mm.

Basically, on one or both sides beyond these two limits (layer L ₀ and layer Lu) beyond layers be mitfahrbei, which, however, are approachable, for example, for set-up or maintenance or other non-operational actions.

The start-up section 78 is designed and / or supported by the said variability in such a way that it also reduces levels which are lower than the maximum or in-progress stack level, the current stack level with the, preferably horizontal, sheet guide level higher for this case, ie.

The control means S83 (S86) may be part of a higher-level machine control or else provided in a decentralized manner and, if necessary, connected to such.

The switching of the stop means 83; 86 takes place z. B. depending on whether a printing material B in the upstream dispensing station I; II, or should be forwarded to another dispensing station II or a sample sheet removal.

In the case of the abovementioned blowing device integrated in the region of the edge 84, for example, an activation and deactivation of a blast air supply takes place as a function of whether a printing material sheet B in the upstream dispensing station I; II, or else to another dispensing station II or a sample sheet withdrawal

Delivery station II or a donor site are transferred. Such

Holding device is z. B. in the event of an intentional re-storage of another sheet B on the stack 1 1, 12 of the upstream discharge station I at least for the time required for this from the movement path of the sheet B removable. By such a holding device entrainment already filed bow B can be prevented, but at least made difficult.

When filing change from the first to a subsequent stack 1 1; 12, z. B. the

Makulaturstapel 1 1 on the good sheet stack 12, the necessary for filing on the first stack 1 1, the sheet B catching stop means 83 are brought out of trajectory of the sheet B in order for the transfer of printing material B, z.

Form "buoyant" Ries and by the fluidic forces of, for example, designed as a gripper carriage 32 holding devices 32, which promote the bow B at full speed, a Trift arises, which can lead to entrainment of the ream or single arch B at the end.

In order to be able to counteract this, one or more stops 83 - as in the first embodiment set forth above - be embodied and movably mounted so that they are in the active state, ie. H. in an active position, in the trajectory of the printing material B are B and this with the leading bow ends facing side, z. B. a stop surface, are effective as a front stop, and in the inactive state, d.

In addition to this, one or more of the movable stop means 83 is associated with a holding means 299 forcibly moved with the movement of the stop means 83 and protruding beyond the stop face in the direction of the incoming printing material sheet 83 in at least one inactive position of the stop means 83 Retains the uppermost substrate sheet B in the region of its downstream edge from being lifted off and entrained by the printing material sheet B to be transferred. Preferably, the holding means 299 comes in the active position of the associated stop means 83 downstream and / or above the movement path of the printed material to be dispensed to the stack 1 1 sheet B and in inactive position of the associated stop means 83 below the path of movement over the stack 1 1 away to be further promoted Substrate sheet B and above the uppermost substrate sheet B of the stack 1 1 to lie.

The stop means 83 associated holding means 299 thus stops at inactive Stop means 83, the uppermost layer of the stack 1 1 down against a lifting and / or entrainment by subsequently to be transferred to printing material B. In this case, the holding means 299 in holding position actually or almost, z. B. with a maximum of one

B. correspond to a length, with which viewed in plan view, the retaining means located in holding position 299 and the stack floor plan at the downstream end of the stack 1 1 in the transport direction T overlap.

The assignment of the holding means 299 can be implemented in a preferred embodiment such that an upper part of the stop means 83, which is in an inactive position, comprises the holding means 299 which reaches upstream over the stack edge. Alternatively, a holding means 299- rigid or via a mechanical coupling - be so connected to the stop means 83, so forced by movement of the stop means 83, the required movement of the holding means 299 takes place and / or conversely with movement of the holding means 299 the relevant movement of the stop means 83rd

Preferably, the stop means 83 as in the active position of the approaching printing material B serving as a front stop stop 83 is formed - especially in the region of its inactive position upper end - for holding down the topmost stack layer as holding means 299 upstream of the stop surface 302 and rising the protrusion 299 in the manner of a retaining finger which is bent upward upstream, comprises at least one retaining means 299 at its downstream end. The hold-down projection 299 or holding finger can also be referred to as a cover mark 299.

In principle, the movement of the stop means 83 can be effected by pivoting, wherein z. B. contrary to the above embodiment, the pivoting for taking the retreat position not downstream, but takes place in the upstream direction. In this case, by the upwardly pivoted stop means 83, for example, hold down the topmost stack sheet. The movement can also take place on any other movement path, provided that the stop means 83 and the retaining means 299 assigned to it assume the positions defined above.

In a preferred embodiment, however, the stop means 83 is arranged and / or stored such that the movement of the retaining means 299 comprising

Lifting means 83 is rectilinear, in particular on a substantially

vertical line, d. H. a maximum of 5 °, in particular by a maximum of 2 °, preferably by a maximum of 1 ° from the vertical deviating direction. Preferably, the movement of the abutment means 83 is guided, so that the or at least one point of the holding surface facing the sheet B to be held is subjected to an exact straight guide.

Preferably, the stop means 83 is arranged and / or stored such that the holding means 299 in the retraction movement in the entire operating range, the z. B. from an upper layer, in which an incoming sheet B is trapped or is to be, to a lower layer in which an incoming sheet B can happen and the upper stack sheet is held down, the stack floor plan in the region of the downstream end stack never leaves completely, ie always one in plan view og overlap between holding means 299 and stack floor plan remains. The retraction movement ends, for example, in contact or at least - in the above sense - close to the contact with the top sheet B of the stack 1.

As already stated above, for moving all, one group or preferably of the single stop means 83; In principle, the drive means 99 may be configured as desired, but is preferably designed as a cylinder-piston system 99, in particular as a pneumatic cylinder 99, which can be acted upon with pressurized fluid.

On the stop means 83 engages over a perpendicular to the direction of movement defined by the linear guide 297 pivot axis 301, a gear member 292, z. B. a coupling 292 at. Spaced from this pivot axis 301 engages over a further, parallel to the first pivot axis 301 extending second pivot axis 298 another gear member 296, z. B. a crank 296, on the coupling 292. The crank 296 is mounted on a frame 303 about one of the first two pivot axes 301; 298 parallel pivot axis 304 pivotally mounted.

Rotary drive of the crank 296 or engaging a drive means 99 at a point spaced from the pivot axis 304 point of the crank 296. In these cases, the above-mentioned guidance of the stop means 83 would be at two spaced apart in the direction of movement advantage.

In a preferred embodiment, multiple or significantly coupling in the direction of movement with the linear guide 297 can be dispensed with, in that the coupling 292, when moved by the crank 296, is defined in a coupling-fixed point spaced from the second pivot axis 298

Movement curve is forced. The coupling-resistant second attack point can

basically in the two first pivot axes 298; 301 connecting

The coupling 292 or the continuation of this section is in this spaced coupling-fixed point via a likewise to the first and second pivot axis 301; 298 parallel further, z. B. fourth pivot axis 306 pivotally mounted.

As mentioned above, the drive center 99 could basically act directly on the crank 296, but here preferably acts on the coupling 292, in particular on the coupling 292 extending section 307. The attack takes place z. B. via a likewise to the first and second pivot axis 301; 298 parallel further, z. B. fifth pivot axis 308 between the second and the fourth pivot axis 298; 306th

Preferably, the attack of the drive takes place on the coupling 292 or the coupling 292 extending portion 307 at a distance from the second pivot axis 298, which is less than half the distance between the first and second pivot axis 301; 298 corresponds. Due to these length ratios, we enable a translation of a short Antriebsmittelhubes in a large adjusting movement.

The attacking on the stop means 86 transmission can - such. As shown in Fig. 14 and Fig. 15 - be designed and arranged such that the pivot axes 298; 301; 304; 306; 308 extend perpendicular to the transport direction T. However, it may alternatively be designed and arranged rotated by 90 °, so that the pivot axes 298; 301; 304; 306; 308 in the transport direction T run.

Actuating means 196 '; 197 '; 198 '; 199 '; 21 1 '; 212 '; 213 '; 214 '; 216; 217; 218; 219; 221; 222; 223; 224; 226; 227,228; 229; 231; 233; 234; 235; 236; 237; 238; 240; 241; 242 provided by its operation via a first signal connection 257; 261 an actuator 63; 106; 147; 202, z. B. drive means 63; 106; 147; 202 or pressure control valve 124 to a setting device 49; 52; 103; 139 of the second delivery station II; I and via a second signal connection 258; 262 an actuator 63; 106; 147; 202; 124, z. B. drive means 63; 106; 147; 202 or pressure control valve 124 a functional of

the institution concerned 49; 52; 103; 139 of the second delivery station II; I corresponding device 48; 51; 103; 139 of the first delivery station I; II adjustable or adjustable, in particular mitgestellt or can be set.

When setting the at least one first dispensing station I; II and one of the first

Dispensing station I; II in the transport path downstream downstream second discharge station II; I comprehensive delivery device 03 for the delivery of printing material B is to adjust or correct the bowing and / or -abläge in the second

Dispensing station II; I at least one adjustable with respect to an adjustment or correction of the sheet guide and / or -abläge in the second delivery station II devices 48; 49; 51; 52; 103; 139 set and adjusted, and wherein as a result of and / or with the placement or setting of this device 49; 139 of the second dispensing station II also setting or setting a functional of the device concerned 49; 52; 103; 139 of the second delivery station II corresponding device 48; 51; 103; 139 of the first

Dispensing station I; II takes place. When setting and / or setting a second delivery station II attributable device 49; 52; 103; 139, a correlated setting and / or setting, ie "matching", of the corresponding means 48, 51, 103, 139 of the first one takes place

Dispensing station II. Collecting can basically be done simultaneously or possibly also with a time delay.

As a result, settings in the first dispensing station I; II, which is less visible than the second or last of the dispensing stations I; II, hit simultaneously with the second.

The pairwise affected devices 48; 49; 51; 52; 103; 139 may in principle be executed differently and / or geometrically arranged, wherein when placing the entrained size then the specific execution

is taken into account. Preferably, the devices 48 to be interposed are; 49; 51; 52; 103; 139, at least what the mechanism of the part size X91 to be provided; v _a b>;139; Y201, executed in the same way. As a result, no complex relationships are to be taken into account when setting but, if desired, at most an absolute and / or an offset proportional to the height of the manipulated variable.

In an advantageous development, when setting one or more of the adjustable devices 48; 49; 51; 52; 103; 139 of the rear and second delivery station I; II setting of the corresponding device 48; 49; 51; 52; 103; 139 of the first delivery station I; II using deposited rules and / or functions, which here z. B. is generally referred to as deposited context 256. This relationship 254 is, for example, in circuit and / or

Data processing means 254 deposited and can be designed as a tabular or functional rule 256.

The context 256 or the provision 256 is set up in particular and programmed, a measure of the setting of the first dispensing station I associated device 48; 103; 139 based on the stored relationship 256 from the in the device 49; 103; 139 to determine the second delivery station II to measure and the drive of the first delivery station I; II institution 48; 49; 51; 52; 103; 139, ie directly to the drive means 63; 106; 147; 202 or the control means S63 associated therewith; S106; S147; S202 (see eg

Fig. 51).

Such a modification of the value over one of a 1: 1 application

different context 256 - z. B. over an absolute and / or an offset proportional to the height of the control value - is preferably when setting or setting formatrelevanter, d. H. to be adapted to the respective format devices 103; 48; 49, z. B. in the lateral positions of the side stop device 103 and when setting the at least one braking device 91 in the transport direction T. It is from

particular advantage, if the placement of the device concerned 103; 48; the first delivery station I; II is done so that the setting there is an oversize in the format compared to that setting at the first dispensing station I; II for the actual format effected. Although this may suffer from the stack quality, it reduces the risk of a disruption during storage.

In contrast, for predominantly transport-relevant, d. H. the movement of the sheets B concerning means 48; 49; 139; 51; 52, z. B. for setting the

Depositing speed v _ab at the braking device 48; 49 and / or the setting of the blowing intensity at the blowing device 51, 52 and / or the release location at the

Release device 139 and / or the placement of the blowing devices 1 13q- at least as far as the target result to be achieved - in a 1: 1-Bezierung stand. In this case, the connection 256 can directly map the 1: 1 relationship or an optionally

take into account the required correction due to different conditions in the design. It is particularly advantageous to use this procedure, which comprises a modification, when the second or rear delivery stations II; I supplied delivery stations I; II only serves to store waste paper. In this case, for example, less high demands are placed on the stack quality and the location of the single sheet determining devices 48; 103 can be adjusted in a more generous way. One opposite to the actual and / or the second delivery station I; II set format larger format set for the first

Dispensing station I; II reduces the risk of stoppers, the bow falls with greater certainty without getting stuck on the stack 1 1.
