DE 100 08 216 A1 discloses a linearly arranged printing unit, one of which Plane through the axes of rotation of the cylinders and the paper web an obtuse angle lock in. The cylinders are mounted in linear guides in guides in the side frame.

From DE 198 03 809 A1 a printing unit is known, the forme cylinder on which Has a circumference in the circumferential direction and a plurality of pressure plates in the longitudinal direction. A transfer cylinder cooperating with the forme cylinder has one double the circumference and is in the circumferential direction with a printing blanket and in Longitudinal direction with two, but offset to each other in the circumferential direction Printing blankets executed.

JP 100 71 694 discloses printing group cylinders with four juxtaposed, and circumferentially offset channels. The printing unit cylinders point a so-called double extent.

CH 3 45 906 discloses a device for bumpless printing, whereby Impacts of four elevators arranged side by side on transfer cylinders double the circumference and joints of four lifts arranged side by side on one Forme cylinders of double circumference are arranged offset from one another.

A double printing unit is known from DE 198 15 294 A1, the rotation axes the printing unit cylinders are arranged in one plane. The cylinders have one four times the width of a newspaper page (double width) and a circumference of one height Newspaper page on. The transfer cylinders have endless sleeves, which are on the side are interchangeable through openings in the side wall.

From US 41 25 073 A printing unit cylinders of simple scope are known, which have a vibration damper. In the case of wider printing presses, the Forme cylinder a double circumference and two pressure plates arranged one behind the other on. Those arranged side by side in the longitudinal direction, receiving the pressure plates Channels are additionally offset from one another in the circumferential direction.

From DE 44 15 711 A1 a double printing unit is known, for the purpose Improving the print quality a plane perpendicular to the paper web to the two Rotation axes of the plane connecting the transfer cylinder by approximately 0 ° to 10 ° is inclined.

JP 57-131 561 discloses a double printing unit arranged in one plane Axes of the printing unit cylinders. The printing unit cylinders are in their phase arranged to each other that channels for fastening the lifts to each other, and in unroll the two printing units working together.

DE 34 12 812 C1 also discloses a double printing unit, the Cylinder axes are arranged in a common plane, which is against the plane the web to be printed runs inclined. Starting and stopping the Transfer cylinder takes place along an almost rectilinear direction of movement using double eccentrics.

EP 08 62 999 A2 discloses a double printing unit with two working together Transfer cylinders, which are used in the eccentric or Double eccentric bushes are stored. In another version, they are stored in levers, which are pivotally mounted eccentrically to the forme cylinder axis.

EP 10 75 945 A1 has a double printing unit arranged in one plane Axes of the printing unit cylinders are known, with several printing unit cylinders in carriages stored, and arranged for the purpose of putting on and off by means of a supporting wall Guide elements are designed to be mutually variable.

From DE 199 37 796 A1 printing unit cylinders are known which run along a linear travel are movable to put them on or off each other. A drive motor is assigned to each cylinder, which together with the cylinder is moved. The movement takes place in a direction parallel to one common level of the printing unit cylinder lies.

In US 58 68 071 A, for the purpose of turning the transfer cylinders on and off stored in slides, which are linear in the side frame along parallel Directions of movement in linear bearings having linear bearings are displaceable.

The invention has for its object a printing unit of a printing press and a To create a process for producing a printed product.

The object is achieved by the features of claims 1 or 10.

The advantages that can be achieved with the invention consist in particular in that Measures a printing press is created, which is compact, low-vibration and is robustly built, has a large variety of products, and is proportionate low manufacturing and maintenance requirements.

Minimizing the number of moving in normal operation and when setting up parts to be executed, e.g. B. the waiver of the movement of all cylinders, of Frame walls, bearings, etc., ensure the robust and inexpensive construction.

With the linear arrangement of the printing unit cylinders, i. H. the arrangement of the Rotation axes of the printing unit cylinders in the print-on position essentially in one Level, the cylinders support each other. This diminishes a relative Deflection of the cylinders. It is even a compensation of the bending line (static) of the Forme and transfer cylinder reachable to each other.

Because the elevators on the cylinders are not continuous over the length of the cylinders, but are held in circumferentially offset channels, a Channel blow when passing through the channel while rolling two together acting cylinder significantly reduced. In an advantageous embodiment, the channels are in the Case of two channels arranged side by side in the longitudinal direction by 180 ° to one another staggered.

The arrangement of the printing couple cylinders and the channels is particularly advantageous, that the offset channels of each cylinder in the area of the opposite lying, offset channel of the cooperating cylinder rolls. So one can Dynamic forces are balanced. With a fixed offset angle of 180 ° and linear arrangement of the cylinders lies for all production rates, i. H. Angular velocities, destructive interference before without an offset angle of Channels must be varied depending on the speed or frequency.

The arrangement of printing unit cylinders of simple scope is particularly advantageous for printed products of smaller and / or variable page size and / or for printing companies with limited space. Compared to producing the same product a double-size press (without gathering) is not a "double" Plate change required. In contrast to a double-size printing press in the collective operation it becomes possible to create an affair from two sides, and thereby creating increased flexibility in the printed product.

The design of all printing unit cylinders with a simple scope allows in comparison Printing units which have one or more cylinders of double circumference much more compact and lightweight design. Are also damaged Rubber blankets to be replaced are smaller and therefore less expensive

The use of printing blankets and printing plates allows the cylinders to be on both sides Stable to store, with a simple, robust and inexpensive construction of the Printing unit cylinder receiving side frame is made possible.

With regard to a robust and simple construction, it is also advantageous if the Parking the printing unit only the transfer cylinders are moved have to. The form cylinders can indeed be spaced apart for the purpose of adjustment Transfer cylinder and, if necessary, ink and, if available, dampening unit can be changed be stored, a turning on and off of the transfer cylinder from each other and from associated forme cylinders, however, is advantageously carried out solely by means of a Movement of the transfer cylinder.

The movement is linear by a specially selected movement in the area of the pressure point Arrangement of the cylinders enables and at the same time switch-on and switch-off devices or - Movements of the forme cylinders avoided. This also contributes to the robust and simple Execution at.

In one embodiment, the transfer cylinders are, for example, in carriages Linear guides mounted in or on the side frame, which move in allows substantially perpendicular to the plane of the cylinder axes. Are the guides on arranged specially designed inserts of the side frame, so the Tenon and enable the simple formation of an encapsulated lubricant space.

A special arrangement of the direction of movement enables fast and safe Parking the forme and impression cylinders as well as the web.

In another embodiment, the transfer cylinders are in levers for this purpose arranged which are pivotally mounted eccentrically to the forme cylinder axis. By the special position of the pivot points and the size of the eccentric (to the axis of rotation of the forme cylinder) in connection with the selected inclination to the plane of the A pressure-forming cylinder or between the web and the plane of the cylinder is a Fast parking of the assigned cylinders or clearing of the web possible. The operational starting and stopping is done only by means of the transfer cylinder, in a preferred embodiment by means of only one actuating movement.

In a third embodiment, the transfer cylinders are in double eccentric bushes stored, which at least in the area close to the pressure point an almost linear and Movement largely perpendicular to the plane of the cylinder axes.

Due to the elevators designed as so-called metal printing blankets on the Transfer cylinders will reduce the effective channel width, reducing excitation of vibrations further advantageously reduced and the non-printing area on the cylinders, d. H. the "white border" on the product or the waste paper is reduced.

One version of the printing unit with cylinders is particularly advantageous Scope and arrangement in one plane, with offset, but mutually channels rolling on one another, and with elevators designed as metal printing blankets on the transfer cylinders.

Especially for washing, changing lifts, etc. cylinders or rollers in printing units from the operating state "pressure on", d. H. a pressure on position against and against each other. The radial movement necessary for this the roller also contains a component of motion in the tangential direction, the Size of the structural design (eccentric, lever, linear guide, as well as their Angle to the nip point) of the adjusting device. Arises from the adjustment in Relative to the operating state, a speed difference on the effective Shell surfaces in the nip point, this implies due to the surface friction of the roller materials used a tangential friction force component which the Adjustment movement is opposite. This makes the adjustment movement inhibited, or their speed limited. This is particularly the case with Printing unit cylinders are important in the case of so-called "winders", since here the high occurring pressures also result in large frictional forces.

It is therefore advantageous in a method for turning cylinders on and off, one relative tangential velocity in the area close to the contact, d. H. in the field of Nip point of two cylinders or rollers working together, by deliberate, with the Movement correlated rotation or rotation of at least one of the cylinders involved or rolling is reduced. In addition to a reduction in the inhibition in the adjustment also an unnecessarily high load (friction, deformation) of the elevators and / or the Shell surfaces of the cylinders or rollers involved avoided.

Embodiments of the invention are shown in the drawings and are in following described in more detail.

A first printing unit 01 of a printing press, in particular one Rotary printing machine, has a first cylinder 02, z. B. a forme cylinder 02, and an assigned second cylinder 03, e.g. B. a transfer cylinder 03, (Fig. 1). In a print-on position AN, their axes of rotation define R02; R03 a level E.

The form cylinder 02 and the transfer cylinder 03 have in their circumference Circumferential direction on the lateral surface at least one fault, for. B. an interruption 04; 06 in the lateral surface effective when unrolling. This interruption 04; 06 may a joint of a leading and a trailing end of one or more Be elevators, for example, by means of magnetic force or cohesive on the Scope are arranged. However, it can also, as in the following Embodiments shown to channels 04; 06 or slots 04; 06 act, which pick up the ends of elevators. The following as channels 04; 06 designated faults are synonymous with other interruptions 04; 06 on the effective surface area, d. H. the outward-facing surface of the with elevators provided cylinder 02; 03.

The forme cylinder 02 and transfer cylinder 03 each have at least two channels 04; 06 (or interruptions 03; 04 etc.). These two channels 04; 06 are in Longitudinal direction of the cylinder 02; 03 in a row, and in the circumferential direction to each other staggered.

Assign the cylinders 02; 03 only a length L02; L03 on which essentially corresponds to two widths of a newspaper page, then only two are in relation to each other Channels 04; offset in the circumferential direction and arranged one behind the other in the longitudinal direction; 06 arranged.

Channels 04; 06 are on the two cylinders 02; 03 they arranged at Rotation of the two cylinders 02; 03 each on one of the channels 06; 04 of each other cylinder 03; 04 unroll. The offset of the channels is preferably 04; 06 each cylinder 02; 03 approx. 180 ° in the circumferential direction. Thus roll after 180 ° Rotation of cylinders 02; 03 at least one pair of channels 04; 06 on each other, while on a longitudinal section a of the cylinder 02; 03 the cylinders 02; 03 undisturbed roll on each other.

The transfer cylinder 01 of the first printing group 01 forms with a third cylinder 07; via a train 08; z. B. a printing material web 08, a printing point 09. This third Cylinder 07 can be used as a second transfer cylinder 07 (FIG. 1) or as a Impression cylinder 07 (Fig. 2), z. B. steel cylinder, or satellite cylinder 07 be executed. The axes of rotation R03 and R07 of those forming the printing point 09 Cylinder 03; 07 stretch a plane D in the ON position (see e.g. Fig. 6 or 13).

5, the axes of rotation R02; R03; R07 of the three interacting cylinder 02; 03; 07 during a print-on position ON in essentially in a common level E, which in this case is level D coincides, and run parallel to each other (see Fig. 5, 12). He knows Satellite cylinder 07 has two pressure points on its circumference, so preferably one second printing unit, not shown, also in the common plane E. arranged. However, it can also define its own level E, which also depends on the its assigned level D is different.

As shown in the embodiment of FIG. 1, it acts as the second Transfer cylinder 07 third cylinder 07 with a fourth cylinder 11, in particular a second forme cylinder 11 with an axis of rotation R11, together, and forms a second printing unit 12. The two printing units 01; 12 form one on both Pages 13 simultaneously printing unit 13, a so-called double printing unit 13th

5 all axes of rotation R02; R03; R07; R11 of the four cylinders 02; 03; 07; 11 during printing, d. H. in the pressure-on position AN in the common plane E or D and run parallel to each other. 6 and 13 shows a corresponding one Printing unit 13, wherein a pair of forme and transfer cylinders 02, 03; 11, 07 a plane E, and the transfer cylinder 03; 07 different from levels E. Form level D.

In the case of the double printing unit 13 (FIG. 1), the cylinders 07; 11 of the second Printing unit 12 channels 04; 06 with those described above for the first printing group 01 Properties with regard to the number and that of the offset to one another. Channels 04; 06 the four cylinders 02; 03; 07; 11 are now preferably arranged so that two Channels 04; 06 two interacting cylinders 02; 03; 07; 11 roll on top of each other.

The forme cylinder 02 and the transfer cylinder 03 have an advantageous design each a length L02; L03, which is four or more widths of a printed page, e.g. B. a newspaper page, e.g. B. 1,100 to 1,800 mm, in particular 1,500 to 1,700 mm and a diameter D02; D03, e.g. B. 130 to 200 mm, in particular. 145 to 185 mm, whose extent U corresponds essentially to the length of a newspaper page, in following "simple scope" (Fig. 3 and 4) ._ The device is also for other scopes advantageous in which the ratio between diameter D02; D03 and length L02; L03 the cylinder 02; 03 less than or equal to 0.16, in particular less than 0.12, or even is less than or equal to 0.08.

In an advantageous embodiment, each of the two cylinders 02; 03 two channels 04; 06 on, which each extend continuously over at least one length, which two Widths corresponds to a newspaper page (Fig. 3).

Each cylinder 02; 03 but also more than two channels 04; 06 may be arranged. In this case, two channels 04; 06 in alignment, or alternately. However, it can for example with four channels 04; 06 the two the end faces of the cylinders 02; 03 adjacent channels 04; 06 in a common escape, and the two "inside" lying channels 04; 06 in a common escape, but in the circumferential direction be arranged offset to the former (Fig. 4).

Are the interruptions 04; 06 actually as channels 04; 06 or slots 04; 06 executed, the channels 04; 06 something longer than the width or double the width of the printed page. Possibly. can two in Channels 04; 06 also slightly in the circumferential direction overlap. This is not the case in FIGS. 1 to 4, which are only shown schematically so detailed can be removed.

Particularly advantageous with regard to the excitation or damping by Vibration caused by channel impact is when the channels 04; 06 on the respective cylinder 02; 03; 07; 11 are offset from each other by 180 °. So they roll Channels 04; 06 between the forme cylinders 02; 11 and the transfer cylinders 03; 07 of the two printing units 01; 12 simultaneously and in the area of the same section in Longitudinal direction of the cylinder 02; 03; 07; 11 from; z. B. on the same page, e.g. B. a side I (Fig. 1, 3 and 4) of the double printing unit 13 in one stage of the cycle, and in the another phase on one side II, or with more than two channels 04; 06 per cylinder 02; 03; 07; 11, for example in the area of the center of the cylinder 02; 03; 07; 11th

Due to the offset arrangement of the channels 04; 06 and the unwinding of all channels 04; 06 in the manner described, and in addition, if necessary, the linear arrangement of all cylinders 02; 03; 07; 11 in a plane E, the excitation of vibrations is significantly reduced. Due to the synchronous and possibly symmetrical unwind on the two printing units 01; 12 there is a destructive interference of the suggestions, which when choosing the Offset of channels 04; 06 on the cylinders 02; 03; 07; 11 by 180 ° from the speed the cylinder 02; 03; 07; 11 or the frequency takes place independently.

Are the interruptions 04; 06 actually as channels 04; 06, they are in an advantageous embodiment with a small width gap, for. B. less than or equal to 3 mm, in the area of a lateral surface of the forme cylinder 02; 11 or transfer cylinder 03; 07 executed which ends of one or more elevators, for. B. one or several blankets, on the transfer cylinder 03; 07 or ends of one or several elevators, e.g. B. one or more printing plates on the forme cylinder 02; 11 receives. The elevator on the transfer cylinder 03; 07 is preferably a so-called Metal printing blanket, which on a metallic base plate has ink-bearing coating. In the case of Transfer cylinders 03; 07 for example by clamping and / or tensioning devices and in the case of forme cylinders 02; 11 by clamping devices in the channels 04; 06 held.

In each of the channels 06 of the transfer cylinder 03 there can be a single, continuous one Clamping and / or tensioning device or it can - in the case of more than one Newspaper page widths through continuous channels - several in a row in the longitudinal direction Clamping and / or tensioning devices can be arranged. The channels 04 of the forme cylinder 02, for example, also each have a single one or more Clamping devices on.

Preferably, the forme cylinder 02; 11 as well as in the Channels 06 of the transfer cylinder 03; 07 a "minigap technology" was used, being in a narrow channel 04; 06 with an inclined leading hooking edge leading end inserted, the elevator to cylinder 02; 03; 07; 11 wound up is, the trailing end also in channel 04; 06 is inserted, and the Anti-slip ends, e.g. B. by means of a rotatable spindle or pneumatic device to be clamped.

However, it can also be used both for the elevator on the forme cylinder 02; 11, as well as for the elevator of the transfer cylinder 03; 07 a as narrow slot 04; 06 executed channel 04; 06 arranged without a clamping device be the one that picks up the ends of the lifts. The ends are here, for example by their shape and / or the geometry of the slot in slot 04; 06 held.

The transfer cylinder 03; 07 have z. B. in an advantageous embodiment (Fig. 3) only two elevators offset in the circumferential direction from each other by 180 °, which each have at least one width, which two widths of a newspaper page equivalent. In this case, the elevators or channels 04 of the forme cylinders 02; 11 complementary to this and must either, as shown, two continuous, each a length of two newspaper page widths, channels 04, or in pairs Adjacent and aligned channels 04 each having a length of one Have newspaper page width. In the former case, each actually shows channel 04 executed interruption 04 of the forme cylinder 02; 11 in an advantageous embodiment two Clamping devices each have a length that is essentially a width of one Newspaper page corresponds to.

The forme cylinder 02; 11 are in an advantageous embodiment with four in the longitudinal direction Forme cylinder 02; 11 bendable lifts arranged side by side, which in Circumferential direction a length of slightly above the length of the printed image Newspaper page, and in the longitudinal direction have a width of about one newspaper page. When arranging continuous channels 04 and only one clamping device per channel 04; 06, which has a length of two widths on a newspaper page, is also possible lifts with a width of two newspaper pages, so-called panorama printing plates, raise.

For printing units 01; 12, for which a need of equipping with panoramic printing plates can be excluded, an arrangement can also be advantageous, the each to side I and the "outer" elevators adjacent to side II align and align the "inner" lifts with each other and to the former Are arranged offset by 180 ° (Fig. 4). This highly symmetrical arrangement leaves additionally reduce the risk of vibration excitation in level E or avoid which is caused by the non-simultaneous passage of channels 04; 06 on Side I and Side II can result. This also alternates between side I and side II alternating tensioning and relaxation of the web 08, and thereby caused Swinging of the web 08 can thereby be avoided.

The said arrangement of interruptions 04; 06 on the respective cylinder 02; 03; 07; 11 and between the cylinders 02; 03; 07; 11 and possibly the linear arrangement of the Cylinder 02; 03; 07; 11 are in training also particularly on cylinder 02; 03; 07; 11 to apply, which have a length L02; L03, which essentially the corresponds to six times the width of a newspaper page. However, it can be an advantage here be the transfer cylinder 03; 07 and / or the forme cylinders 02; 11 with one Diameter D02; Execute D03, which results in a scope that in corresponds essentially to twice the length of a newspaper page.

For a technically simple and robust design of the double printing unit 13, the Forme cylinder 02; 11 in an advantageous embodiment with respect to their axes of rotation R02; R11 fixed. For switching the printing units 01; 12 are the Transfer cylinder 03; 07 with respect to their axes of rotation R03; R07 movable executed and are simultaneously from the associated forme cylinder 02; 11 and from interacting transfer cylinder 03; 07 adjustable, or adjustable to this. In this version will only be in normal operation of the press Transfer cylinder 03; 07 moves while the forme cylinder 02; 11 in their fixed, if necessary previously adjusted position remain. For the purpose of adjustment, the forme cylinders 02; 11 however in appropriate devices, e.g. B. in eccentric or double eccentric bushings, in Linear guides or in levers.

The transfer cylinder 03; 07 can, as in FIGS. 5 to 7 schematically, as well as in 8 to 11 shown in more detail, along a linear travel path 16, or how in Fig. 12 and 13 schematically and in Fig. 14 and 15 shown in more detail along a curved path 17 to be movable. Travel 16 and 17 and the Transfer cylinder 03; 07 in a print-down position AB are in FIGS. 5, 6 and 12 shown in dashed lines.

In a further embodiment, not shown, the adjustment path 16; 17 through the Storage of the transfer cylinder 03; 07 in eccentric bushings, not shown, especially in double eccentric bushings. With double eccentric bushings in the area of the pressure-on position AN an essentially linear adjustment path 16, in the of Pressure area 09 further away, however, a curved travel path 17 if necessary generate which faster or larger parking of the transfer cylinder 03; 07 of the cooperating transfer cylinder 07; 03 as from the assigned Forme cylinder 02; 11 or vice versa allowed. Also for the use of eccentrics the storage on side I and on side II of the double printing unit 13 is advantageous.

The following (FIGS. 5 to 11) are exemplary embodiments for the printing group 01; 12 set out, wherein at least one of the transfer cylinders 03; 07 along a linear Travel 16 is movable (Fig. 5):

The linear travel 16 takes place by means of linear guides not shown in FIG. 5, which are arranged in or on the side frame, also not shown in FIG. 5. The bearings in a linear guide are made for the robust and low-vibration Construction preferably on side I and on side II of the double printing unit 13.

In Fig. 5 the course of the web 08 is the one in the print-on position ON Pressure point 09 shown. The level E of the double printing unit 13 (Fig. 5) or respective printing group 01; 12 (Fig. 6) and the plane of web 08 intersect advantageous embodiment at an angle α of 70 ° to 85 °. Assign the Transfer cylinder 03; 07 has a circumference which is approximately one Newspaper page corresponds, the angle α z. B. about 75 ° to 80 °, preferably about 77 °; have the transfer cylinder 03; 07, however, has a scope which is roughly the same Corresponds to the length of two newspaper pages, the angle α z. B. 80 to 85 °, preferred approx. 83 °. This choice of the angle α contributes to the safe and fast on the one hand Clearing the web 08 and / or the parking cylinder 03; 07 from each other with minimized travel 16 and minimizes negatives Influences on the printing result, which by the measure of a partial wrapping the or the transfer cylinder 03; 07 is significantly influenced (duplication, Lubrication etc.). With an optimized arrangement, the required linear travel 16 is everyone Transfer cylinder 03; 07 less than or equal to 20 mm for the on / off of the Transfer cylinder 03; 07 to each other / for an exemption from the web 08 in an imprint operation, however, up to 35 mm.

If the axes of rotation R02; R03; R07 from form, transfer and Impression cylinder 02; 03; 07 in plane E (Fig. 5) forms the direction of the linear Travel 16 with the plane E, which coincides here with the plane D, an angle δ, which is essentially 90 °. The direction of the linear travel path 16 also forms a plane of the incoming or outgoing web 08 in the region of an obtuse angle β an angle γ between path 08 and plane E. In the case of a straight run of the web 08 applies β = 180 ° - α, where γ z. B. is 5 to 20 °, in particular 7 to 13 °. The dull one Angle β is then with linear printing unit 01 and web 08 running straight ahead preferably at 95 ° to 110 °.

In the event that only one of the form and the associated transfer cylinder 02, 03; 11, 07 determine the plane E in the position of engagement (FIG. 6), the angle γ is between Travel 16 and the level of the web 08 preferably greater than or equal to 5 °, z. B. between 5 ° and 30 °, especially between 5 ° and 20 °. The angle γ is in particular for forme cylinder 02; 03; 07; 11 simple circumference greater than or equal to 10 °. The angle γ is, however, limited in such a way that the angle δ between that in the direction Forme cylinder 02; 11 facing part of level E and the direction of the parking path 16 is at least 90 °. So is a quick and safe parking of the Transfer cylinder 03; 07 simultaneously from the web 08 and the assigned Forme cylinder 02; 11 guaranteed.

The relationships mentioned are for "non-straight" run of web 08 below Taking into account the obtuse angle between path 08 and level E apply accordingly.

Regardless of the relative course of the path 08, the direction of the travel path 16 (in the direction of the cut-off) is selected such that an angle ϕ between the plane D and the travel path 16 in the direction of the cut-off is at least 90 ° and at most 120 °, in particular from 90 ° to 115 ° lies. However, the angle ϕ is again limited in such a way that the angle δ is at least 90 °.

The double printing unit 13 is multiple, as shown in FIG. 7, for example twice, in a printing unit 19, e.g. B. a so-called. H-printing unit 19, in a common Side frame 20 can be used. In Fig. 7 was on the separate designation of the Upper double printing unit 13 similar parts for the one below Double printing unit 13 omitted. If all cylinders 02; 03; 07; 11 with one The extent, which essentially corresponds to the length of a newspaper page, can be assumed Installation space, d. H. save at a height h of the printing unit 19. Of course, this applies also for individual printing units 01; 12, for double printing units 13 and for other types configured printing units, which several printing units 01; 12 have. The priority can, however, instead of a saving in height h with an improved Accessibility of cylinders 02; 03; 07; 11, e.g. B. for changing lifts, Cleaning work and washing, maintenance etc., lie.

The pressure on or off position ON; AB is for clarification in all figures shown exaggerated. Fig. 7 indicates the transfer cylinder 03; 07 in one second possible position along the linear travel path 16, here for example the upper double printing unit 13, e.g. B. for the printing form change in the Print-down position AB (solid), and the lower double printing unit 13, z. B. to continued pressure, is operated in the pressure-on position ON (solid).

In an advantageous embodiment, each of the printing units 01; 12 at least one own drive motor 14, indicated only by dashed lines in FIG. 7, for the rotary drive of cylinders 02; 03; 07; 11 on.

In an embodiment shown schematically in FIG. 7 (above) this can be done by a single one Drive motor 14 for the respective printing group 01; 12, which in this case is in a advantageous embodiment first on the forme cylinder 02; 11 drives, and from there via a mechanical drive connection, e.g. B. spur gears, timing belts, etc. on the Transfer cylinder 03; 07 is driven. However, it may be due to lack of space Because of the torque flow can also be advantageous from the drive motor 14 to the Transfer cylinder 03; 07 and from there to the forme cylinder 02; 11 to drive.

With a high degree of flexibility in the various operating situations such as Production printing, registration, elevator change, washing, web feed etc. Printing unit 01; 12 in a version of its own, and of the other drives mechanically independent drive motor 14 per cylinder 02; 03; 07; 11 (Fig. 7, below).

The type of drive from FIG. 7 (top and bottom) are each shown as examples and thus apply to the other example.

In an advantageous embodiment, the drive motor 14 is coaxially driven between axis of rotation R02; R03; R07; R11 and motor shaft, if necessary with an angle and / or offset compensating clutch, explained in more detail below. He can, if one "With moving" of the drive motor 14 or a flexible coupling between the Drive motor and the cylinder 02 to be moved if necessary; 03; 07; 11 can be avoided should, however, also be done via a pinion.

A first exemplary embodiment for realizing the linear adjustment path 16 by means of 8 and 9.

The pin 23 of at least one of the transfer cylinders 03; 07 are for example in bearing housings 24 designed as slides 24 are rotatably supported in radial bearings 27 (in 8 and 9 only the arrangement in the region of an end face of the cylinders 02; 03; 07; 11 ) Shown. The bearing housing 24 or slide 24 are in linear guides 26 movable, which are connected to a side frame 27.

The linear guides 26 are for the linear arrangement of the double printing unit 13 in advantageous embodiment almost perpendicular to the plane E or D, d. H. δ = 90 ° (see Fig. 5), oriented. In a preferred embodiment, each bearing housing 24 or Carriage 24 provided two linear guides 26 which run parallel to each other. The linear guides 26 of two adjacent transfer cylinders 03; 07 run preferably parallel to each other.

The linear guides 26 can directly in an embodiment, not shown Walls of the side frame 27, in particular on walls of openings in the Side frame 27 may be arranged, which is almost perpendicular to the end face of the cylinder 02; 03; 07; 11 run.

In the exemplary embodiment according to FIGS. 8 and 9, the side frame 27 has an opening an insert 28, e.g. B. a so-called. Bell 28 on. The linear guides 26 are on or in this bell 28 arranged.

In an advantageous embodiment, the bell 28 has an area which is in the direction Cylinder 02; 03; 07; 11 emerges from the alignment of the side frame 27. The Linear guides 26 are arranged in or on this area of the bell 28.

The distance between the two opposite side frames 20 (only one shown) is oriented i. d. Usually the broadest aggregate, e.g. B. on the wider inking unit 21, and usually causes a correspondingly longer pin on the cylinders 02; 03; 07; 11. Advantageous at the above The arrangement is that the pins of the cylinders 02; 03; 07; 11 can be kept as short as possible.

In one development, the bell 28 has a cavity 29, which at least is partially arranged at the level of the side frame 20. In this cavity 29 are, as shown schematically in Fig. 9, the rotary drives of the cylinders 02; 03; 07; 11 with the pins of the cylinders 02; 03; 07; 11 connected.

Particularly advantageous when driving cylinders 02; 03; 07; 11 (see e.g. Fig. 11) can also drive connections such. B. cooperating drive wheels 30, be accommodated in this cavity 29. On the transfer cylinder 03; 07 can in advantageous embodiment (Fig. 9) with drive motor 14 fixed to the frame between Transfer cylinder 03; 07 and drive motor 14 an angle and offset compensating clutch 61 may be arranged to the on and off movement of the Transfer cylinder 03; 07 to compensate. This can be a double joint 61 or in an advantageous embodiment as an all-metal coupling 61 with two torsionally rigid but axially deformable plate packs are executed. The all-metal clutch 61 can at the same time compensate for the offset and the resulting change in length. It is essential that the rotary movement is transmitted without play.

In particular in the case of the coaxial drive of the forme cylinder 02; 11 has the Drive of the forme cylinder 02; 11 between pin 51 and drive motor 14 a Coupling 62, which for adjusting the side register at least one axial Relative movement between cylinder 02; 11 and drive motor 14 takes. Too too Manufacturing tolerances and any necessary movements of the forme cylinder 02; 11 to To accommodate adjustment purposes, the clutch 62 is at least a slight angle and offset compensating clutch 62 executed. This is also more advantageous Design as an all-metal coupling 62 with two torsionally rigid but axially deformable Lamella packs executed. The linear movement is due to the axial direction positively connected to the pin 51 or a shaft of the drive motor 14 Lamella packs added.

If lubrication, for example a lubricant or oil chamber, is required, then the Cavity 29 can be limited in a simple manner by means of a cover 31 (dashed) without that this increases the width of the machine or from the side frame 20 protrudes. The cavity 29 can then be encapsulated.

The arrangement of the bell 28 thus shortens the length of the pins, which is a reduction which results in vibration and enables a simple and variable construction, which are suitable for a wide variety of drive concepts, and for more extensive ones Identical construction the change between the concepts - with or without Drive connections, with or without lubricant, with or without additional Couplings - allowed.

The drive of the respective bearing housing 24 or slide 24 in the linear guides 26 takes place in the embodiment shown schematically in FIG. B. by means of linear Drives 32, e.g. B. each a screw 32, z. B. a threaded spindle, which of an electric motor, not shown, is driven. The electric motor can do this be controllable with respect to a rotational position. To limit the travel in the ON position can be a fixed but adjustable stop for the bearing housing 24 be provided.

The drive of the bearing housing 24 can also be done by means of a lever mechanism respectively. This can also be done by means of an electric motor or at least be driven by a pressure medium cylinder. Will the Lever mechanism by means of one or more pressurizable medium Cylinder driven, so the arrangement is the actuating movement on the two sides I and II synchronizing synchronous spindle is an advantage.

The connection of the transfer cylinder 03; 07 to the side frame 20 or the bell 28 is designed as follows in the exemplary embodiment according to FIG. 9: The bell 28 has supporting walls 33 on both sides of the slide 24 to be guided, which one of the two corresponding parts of the linear guide 26. this part can possibly already be part of the support wall 33, or incorporated into this. The other corresponding part of the linear guide 26 is arranged on the slide 24 or incorporated into it or having it. In an advantageous embodiment, the Carriage 24 through two such, on two opposite sides of the carriage 24 arranged linear guides 26 out.

The on the support walls 33 (or without bell 28 directly on the side frame 20) arranged parts of the guides 26 thus include the arranged between them Carriage 24. The active surfaces of the side frame 20 or the bell 28 connected parts of the linear guide 26 have in the facing the pin 23 Half space. To reduce the friction between the interacting parts of the Guides 26 are in an advantageous embodiment bearings 34, z. B. linear bearing 34, In particular, roller bearing cages 34 that enable a linear movement are arranged.

The two parts of the two guides 26 in the ideal state allow movement of the slide 24 only with a degree of freedom as a linear movement. For this is the entire arrangement in a perpendicular to the axis of rotation R03; R07 and perpendicular to Direction of movement of the carriage 24 lying direction against each other essentially tensioned without play. For example, the part of the guide close to the forme cylinder points (in Fig. 9 with larger dimensions) on a clamping device, not shown.

The carriage 24 mounted in the manner described has, for. B. on a radial after Inside facing side of the transfer cylinder 03; 07 facing Recess, the radial bearing 27 receiving the pin 23.

In a second, and in particular with regard to the installation space and a robust one Construction advantageous embodiment (Fig. 10 and 11), have the active surfaces of the parts of the linear guide 26 connected to the side frame 20 or the bell 28 in the half-space facing away from the pin 23. For this purpose, these parts of the Linear guide on one connected to the bell 28 (or the side frame 20) Carrier 36 arranged. The carriage 24 has the parts associated with it Linear guide 26 in a side frame 20 or bell 28 facing Recess on. These parts can be arranged in the recess as components, or but already in the carriage 24 in an inwardly facing surface of the recess be incorporated. As in the exemplary embodiment according to FIG. 9, the carriage 24 has a to the transfer cylinder 03; 07 facing recess in which the radial bearing 27 for receiving the pin 23 is arranged. In the present embodiment a running surface for rolling elements of the radial bearing 27 designed as a rolling bearing 27 already incorporated in an inward surface of the recess.

The parts of the guides 26 arranged on the slide 24 thus comprise the carrier 36, or the parts arranged on the carrier 36, on the side frame 20 or on the bell 28 of the guides 26.

At least one of the two the transfer cylinder 03; 07 assigned carrier 36 has in an advantageous embodiment an oriented in the direction of movement of the slide 24, Elongated hole not visible in the figures for carrying out the linear movement Pin 23 on. This elongated hole is also not at least partially aligned with one visible, arranged in the bell 28 (or in the associated side frame 20) Long hole. These slots are from the pin 23 or one with the pin 23rd connected shaft, which is used for the rotary drive of the Transfer cylinder 03; 07 with a drive wheel 30 (see FIG. 9) or the Drive motor 14 is in drive connection.

The drive of the carriage 24 can be one of those already in the first embodiment mentioned way. Fig. 11 shows the execution of a as a lever mechanism executed actuating means. The carriage 24 is articulated via a coupling 37 with a lever 38 connected, which around a substantially parallel to the axis of rotation R03; R07 the transfer cylinder 03; 07 extending axis is pivotable. in the Embodiments are for synchronizing the actuating movement of both Transfer cylinder 03; 07 the coupling 37 of the two adjacent carriages 24 for the interacting transfer cylinder 03; 07 with the three-arm lever 39 executed lever 38 articulated. The lever 38 is driven by means of at least one actuator 39, e.g. B. by means of one or by means of two (as in FIG. 10) cylinder 39 pressurizable with pressure medium. When actuating actuator 39 and Swiveling the lever 38 in one direction (here clockwise), the two transfer cylinders 03; 07 with their axes of rotation R03; R07 to level E brought, at the same time to each other and to the respective plate cylinder 02; 11 be employed. By turning in the other direction, the Transfer cylinder 03; 07 from each other and from the associated forme cylinders 02; 11th

In particular in the event that the actuator 39 is pressurizable Cylinder 39 is designed, the arrangement of stops 41 is advantageous against which the respective slide 24 is placed in the ON-ON position. These attacks are adjustable to adjust the end position for the transfer cylinder 03; 07 to enable in which their axes of rotation R03; R07 to lie in level E. come. The system becomes very rigid when the slide 24 hits the stop 41 or the stops 41 (two in FIG. 10) are pressed with great force.

As in the present case, the carriages 24 of the two neighboring ones Transfer cylinder 03; 07 placed over a common actuating means, so it is in Further development of the exemplary embodiments is advantageous if the adjusting means between the respective slide 24 and the first common part of the actuating means at least in flexible limits. For this purpose, each coupling 37 has the type of A strut 42, e.g. B. a plate spring assembly 42. During pressure on position To the spring assembly 42 of the one transfer cylinder 03; 07 is compressed is the other transfer cylinder 07; 03 associated spring assembly 42 under Tensile stress.

To synchronize the linear movement of both sides of the transfer cylinder 03; 07 is a shaft 43, z. B. a synchronous shaft 43, with the on both sides of the Transfer cylinder 03; 07 arranged adjusting means in connection. To this end is in the example the shaft 43 with the two, each a side frame 20 on side I and II assigned levers 38 rotatably connected. This also represents the Pivot axis for the lever 38.

An adjusting device can be used for the exemplary embodiments in FIGS be provided, which, especially during assembly and / or when Configurations and / or conditions have changed, a basic setting for the Distances of the axis of rotation R02; R03; R07; R11 enables. Individuals can do this the cylinder 02; 03; 07; 11, e.g. B. the forme cylinder 02; 11, possibly in an eccentric bushing be stored. At least one of the transfer cylinders 03; 07 can Adjustment can be adjustable in a radial direction. For example, the Side frame 20 or the bell 28 associated parts of the linear guides 26 or Carrier 36 in elongated holes sufficient for adjustment purposes with the side frame 20 or the bell 28 may be connected. Also an eccentric and lockable bearing of the radial bearing 27 in the carriage 24 is possible.

The following (FIGS. 12 to 18) are exemplary embodiments for the printing group 01; 12 set out, wherein at least one of the transfer cylinders 03; 07 along one Curved travel 17 is movable (Fig. 12):

In the lever 18 shown schematically in FIG. 12, one of the transfer cylinders 03 pivoted about a pivot axis S. The pivot axis S is here z. B. in the level E. The lever 18 has a length between the storage of the Axis of rotation R03; R07 of the transfer cylinder 03; 07 and the pivot axis S which is larger than the distance of the axis of rotation R03; R07 des Transfer cylinder 03; 07 from the axis of rotation R02; R11 of the assigned Forme cylinder 02; 11 in print-on position ON. This means that it is switched off simultaneously of cooperating transfer cylinder 03; 07 and the associated Forme cylinder 02; 11, and vice versa for starting.

However, the pivot axis S can in particular also, as described in more detail below, in otherwise eccentric to the axis of rotation R02; R11 of the assigned Forme cylinder 02; 11, e.g. B. at a distance from the plane E. The Storage in a lever 18 is preferably carried out on side I and on side II of the Double printing unit 13.

Also in FIGS. 12 and 13 is the course of the web 08 through the ON in the print-on position located printing point 09 shown. The plane E of the double printing unit 13 (FIG. 12) or the respective printing group 01; 12 (Fig. 13) and cut the plane of the web 08 here also in an advantageous embodiment at an angle α of 70 ° to 85 °. Point the transfer cylinder 03; 07 has a circumference which is approximately one Newspaper page corresponds, the angle α z. B. about 75 ° to 80 °, preferably about 77 °; have the transfer cylinder 03; 07, however, has a scope which is roughly the same Corresponds to the length of two newspaper pages, the angle α z. B. 80 to 85 °, preferred approx. 83 °. Here, too, this choice of the angle α contributes to the safe and quick release the web 08 and / or the parking cylinder 03; 07 from each other minimized travel 16 at. On the other hand, it minimizes negative influences on the Printing result, which is determined by the extent of partial wrapping of the Transfer cylinder 03; 07 is significantly influenced (duplication, lubrication etc.)

The double printing unit 13 (here in a linear design) is multiple, as in FIG. 14 shown for example twice, in a printing unit 19, for. B. the so-called H-printing unit 19, can be used in the common side frame 20.

B. a one or multi-part coupling 46, for example via a lever or toggle mechanism 46, causes the transfer cylinder 03; 07 simultaneously from or to the associated forme cylinder 02; 11 and from or to each other Transfer cylinder 07; 03. The toggle mechanism 46 is articulated with the lever 18 and connected to a pivot point fixed to the frame. Advantageously double acting pressure medium cylinder acts z. B. on a movable joint of the Toggle mechanism. The axes of rotation R02 remain for this process; R11 the Forme cylinder 02; 11 at rest. So that the movement of the two arranged on the front Lever 18 per transfer cylinder 03; 07 takes place synchronously, the adjusting means 44 can the two adjusting means 44 connecting shaft 47, z. B. have a synchronous shaft 47 or be connected to one. To the desired, e.g. B. linear arrangement of Cylinder 02; 03; 07; 11, a stop 48 is provided for each lever 18, which is preferably adjustable.

The eccentricity e-S of the pivot axis S to the axis of rotation R02; R11 des Forme cylinder 02; 11 is between 7 and 15 mm, in particular about 9 to 12 mm. The Eccentricity e-S is in the position of the transfer cylinder 02; 03; 07; 11, d. H. the Axes of rotation R03; R07 are in the above Level D, oriented so that an angle ε-S between the plane D of the cylinder 03; 07 and the Connection plane V of the pivot axis S and the axis of rotation R02; R11 between 25 ° and 65 °, advantageously between 32 ° and 55 °, in particular between 38 ° and 52 °, the pivot axis S preferably in the range of an obtuse angle β between level D and the incoming or outgoing web 08, and further from the printing point 09 is spaced as the axis of rotation R02; R11 of the associated forme cylinder 02; 11th With vertical, and, except for one possibly caused by partial wrapping Offset, straight web run and an angle of 77 ° between the plane D and the plane Bahn 08, the eccentric e-S z. B. an angle of 12 to 52 °, advantageously 19 to 42 °, in particular 25 to 39 ° to the horizontal H.

Ideally, d. H. with never changing conditions and tolerance-free production, the arrangement as described so far is sufficient without further adjustment mechanisms Requirements for starting and stopping the printing units 01; 12 or des Double printing unit 13.

However, to compensate for any manufacturing tolerances that may arise and / or a Basic settings for the elevators, substrates, etc. are other Adjustment options given for adjustment purposes:

The axis of rotation R02; R11 of the forme cylinder 02; 11 is adjustable, e.g. B. also eccentric to its attachment to the side frame 20, here to a bore 49, stored.

The aforementioned statements on the drive and for moving the Transfer cylinder 03; 07 and the execution of the lever 18 or the Linear guide 26 are equally applicable to printing units in which the cylinders 02; 03; 07; 11 do not all have the same circumference or diameter (FIG. 19). So can the forme cylinder or cylinders 02; 11 a scope U have which in the circumferential direction a pressure side, for. B. the long side of a Newspaper page, has (in the following "simple scope"). The one working together Transfer cylinder 03; 07 z. B. a circumference or diameter, which an integer multiple (greater than 1) that of the forme cylinder 02; 11 corresponds, d. H. he has z. B. a scope of two or even three printed pages in Newspaper format (or adapted to other formats accordingly).

If the printing point is 03; 07 and a z. B. as Satellite cylinder 07; 03 executed impression cylinder 07; 03 formed, so can also forme and transfer cylinder 02; 11; 03; 07 have a simple scope and the associated impression cylinder 07; 03 be made many times larger.

The training mentioned also advantageously increases Rigidity of the printing unit reached. This is particularly beneficial in connection with Cylinders 02; 03; 07; 11, which have a length that is at least four or even six standing printed pages, especially newspaper pages, corresponds.

With the measures set out in the exemplary embodiments, it is possible to: Printing unit 01; 12 with long, slim cylinders 02; 03; 07; 11, which is an above Have a ratio of diameter to length of approx. 0.08 to 0.16, robust and to build or operate with low vibrations, while at the same time requiring little effort Space, operation and frame construction is required. This applies in particular to Forme cylinders 02, 11 "simple circumference", d. H. with a newspaper page on the circumference, however, double the width, i. H. with four newspaper pages on the length of the cylinder 02; 03; 07; 11th

In the exemplary embodiments mentioned, at least one of the is advantageous Transfer cylinder 03; 07 adjustable so far that the retracted web 08 during of the printing operation by means of other printing units without contact through the printing point 09 is feasible.

The cylinders 02; 03; 07; 11 can be used for all exemplary embodiments as described either in pairs or individually, each with its own drive motor 14 be driven. For special needs, for example for only one-sided Imprinter operation or just the need to change the relative Angular position of the forme cylinder 02; 11 to each other, a drive is also possible, wherein one of the forme cylinders 02; 11 of a printing group 01; 12 its own drive motor 14, and the remaining cylinders 02; 03; 07; 11 of the printing group 01; 12 a common Have drive motor 14. A configuration of four or five cylinders 02; 03; 07; 11 with three drive motors 14 can be advantageous: in the case of a double printing unit 13 z. B. each have a drive motor 14 on the forme cylinder 02; 11 and a common one for the Transfer cylinder 03; 07; in the case of a five-cylinder or satellite printing unit, e.g. B. per pair of forme and transfer cylinders 02; 03; 07; 11 one and for the Satellite cylinder has its own drive motor 14.

As exemplified above in FIGS. 11 and 17, the four cylinders 02; 03; 07; 11 each in pairs by a drive motor 14 depending on the requirement of Forme cylinder 02; 11 or from the transfer cylinder 03; 07 ago driven by rotation. The drive wheels 30 each forming a transmission between the forme cylinder 02; 11 and the respectively assigned transfer cylinder 03; 07 each form with the assigned drive motor 14 a drive connection. The two pairs of Drive wheels 30 are preferably arranged relative to one another in such a way that they disengage stand, for example, by axially offset arrangement, d. H. in two Drive levels.

The design of the co-operating drive wheels (30) can be advantageous here. between forme and transfer cylinder 02, 03; 11, 07 each with one Straight toothing in order to move one of the two cylinders 02; 03; 07; 11 enable, but without changing the relative position in the circumferential direction. The latter also applies to a possibly arranged pinion between the drive motor 14 and the Drive wheel of the forme cylinder 02; 11 when the pair on the forme cylinder 02; 11 not is coaxially driven. For this purpose, a cooperating pair of links in the Drive connection between drive motor 14 and forme cylinder 02; 11 straight teeth and axially movable against each other to the axial movement of the Forme cylinder 02; 11 without ensuring twisting at the same time. The in Fig. 9 and 11 drive situations shown in each case are shown on the two Versions for the realization of the linear movement to be transferred alternately.

The drive motors 14 are of an advantageous design for all the cases mentioned arranged fixed to the frame. Should the cylinder 02; 03; 07; 11 driving drive motor 14 deviating from this, however, be arranged in a cylinder-fixed manner, so it can during the Actuating movement and / or adjustment of the cylinder 02; 03; 07; 11 in a variant also on a corresponding (or the same) tour or corresponding lever, e.g. B. carried on an outside of the side frame 20 become.

In particular in the embodiment with a drive motor 14 which is fixed to the frame and which is based on the transfer cylinder 03; 07 (the individually or in pairs driven cylinders 02; 03; 07; 11), it is advantageous, as shown in Figs. 9 and 16, for example, the angle and To arrange offset compensating clutch 61. As in Figs. 9, 11 and 16 illustrated by way of example, has a coaxially driven forme cylinder 02; 11 the drive the coupling 62 described between the pin 51 and the drive motor 14.

The drive motor 14 is advantageous as an electric motor, in particular as Asynchronous motor, synchronous motor or as a DC motor.

In an advantageous development is between each of the drive motors 14 and cylinder 02 to be driven; 03; 07; 11 a gear 63 is arranged. This gear 63 can be connected to the drive motor 14 attachment gear 63, z. B. a Planetary gear 63 be. However, it can also be designed as a different one Reduction gear 63, e.g. B. from pinion or belt and drive wheel.

A single encapsulation of each gear 63, z. B. as individually encapsulated Attachment gear 63. The lubricant spaces thus generated are spatially limited and prevent pollution of neighboring machine parts and contribute to Increase in product quality. In the case of using the bell 28 (Fig. 11) can the gears between the form and transfer cylinders 02, 03; 07, 11 in the cavity 29 arranged, and be encapsulated as a lubricant chamber to the outside.

However, it is generally regardless of the design as single or in pairs Driven cylinder 02; 03; 07; 11 advantageous, the drive units each encapsulated, d. H. each with its own lubricant chamber. One of the above single encapsulation, for example, extends around the paired drive of two Cylinders 02, 03; 11, 07 or - especially in the case of the bell described above 28 - around both couples. A bell 28 can also be used for a pair of two cylinders 02; 03; 07; 11 be executed. The latter is, for example, in the sense of a Modularization is an advantage.

In a further development of the exemplary embodiments, it is advantageous if that too respective forme cylinder 02; 11 assigned inking unit 21 and, if available, the assigned dampening unit 22 from one, from the drive of the printing unit cylinder independent drive motor is driven in rotation. In particular, it can Inking unit 21 and any existing dampening unit 22 each have their own Have drive motor. In the case of an anilox inking unit 21, the anilox roller, and in the case of a roller inking unit 21, the distributor cylinder or cylinders can be used individually or be driven in groups by rotation. Also the distribution cylinder or cylinders Dampening unit 22 can be rotated individually or in groups his.

The execution of the cylinder 02; 03; 07; 11 double width and - at least the forme cylinders 02; 11 - with "single scope" enables in contrast to printing presses with double Scope and simple width a significantly higher product variability. The maximal The number of possible printed pages is the same, but in the case of single-width Printing units 01; 12 double scope in the collection plant in two different "Books" or "booklet". In the present case the double-wide printing units 01; 12 After printing, the (double-wide) webs 08 become longitudinal cut. In order to achieve a maximum stapling strength, one or more Partial webs in the so-called folded superstructure or reversible deck guided one above the other and z. B. on folded into a booklet using a folder without a collection company. Are such strengths not necessary, some partial webs can be overlaid, others however be guided together on a second former and / or folder. It can but also two products of the same thickness without being transferred to two folders be led. There is therefore a variable strength of two different products. In the case of a double folder or two folders, there are at least two Depending on the arrangement, the two booklets or Products next to or on top of each other to one side of the printing press, or to the on both sides.

The double-width printing press of simple size has a high degree of variability especially in the grading of the possible page numbers in the product, in the so-called "Escapade". While the strength per booklet (layer) for the printing press with double Scope and simple width in the collection operation (i.e. maximum product strength) only can be varied in steps of four printed pages, the double width described Printing machine of simple scope a "fling" from two sides (z. B. in Newspaper printing). The product strength and especially the "distribution" of the printed pages on different issues of the overall product or products is considerably more flexible.

After the web 08 is cut lengthwise, the partial web is either on one different folding former and / or folder for the corresponding partial web led, or it is turned to the escape of the latter. I.e. in the second The partial web falls before, during or after turning, but before merging with the "straight tracks", brought into the correct longitudinal or cutting register. This is in dependence on the channels 04; 06 one Cylinder 02; 03; 07; 11 in an advantageous embodiment by appropriate execution of Turning decks (e.g. preset distances between the bars or the path sections) considered. The fine adjustment or control is made with the travel ranges of the Cutting register regulation for the relevant partial web and / or partial web strand made to partial lanes of two different running levels if necessary to bring each other in register.

The forme cylinder 02; 11 is now in the circumferential direction with and in the longitudinal direction At least four standing printed pages can be loaded in broadsheet format (Fig. 20). Alternatively, this forme cylinder 02; 11 also optionally in the circumferential direction with two and in the longitudinal direction with at least four lying printed pages in tabloid format (Fig. 21) or in the circumferential direction with two and in the longitudinal direction with at least eight standing printed pages in book format (Fig. 22) or in the circumferential direction with four and in Longitudinal direction with at least four lying printed pages in book format (Fig. 23) by means of one and its longitudinal direction in the circumferential direction of the forme cylinder 03 at least one flexible printing plate that can be arranged on this.

By means of the double-width printing press and at least the forme cylinders 02; 11 simple scope are thus depending on the occupancy of the forme cylinder 02; 11 with lying Tabloid pages or standing newspaper, especially broadsheet pages, with lying or standing book pages different products depending on the used Width of the web 08 can be produced:
