The invention has for its object to provide a printing unit of a printing press create.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular that by the Measures a printing machine is created, which compact, low vibration and robust, has a high production diversity, and a relative requires low manufacturing and maintenance costs.

Minimizing the number of moving in normal operation and during setup to be executed parts, z. B. the renunciation of the movement of all cylinders, from Frame walls, bearings, etc., ensures the robust and cost-effective design.

With the linear arrangement of the printing cylinder, d. H. the arrangement of Rotation axes of the printing cylinder in pressure-on position substantially in one Level, the cylinders support each other. This reduces a relative Bend of the cylinders. It is even a compensation of the bending line (static) of the Form and the transfer cylinder to each other achievable.

Since the elevators on the cylinders do not pass through the length of the cylinders, but held in channels offset in the circumferential direction is a Channel strike during the passage of the channel while rolling two together acting cylinder significantly reduced. In an advantageous embodiment, the channels are in Case of two longitudinally juxtaposed channels by 180 ° to each other staggered.

Particularly advantageous is the arrangement of the printing cylinder and the channels such, that the staggered channels of each cylinder in the area of opposite lying, offset channel of the cooperating cylinder rolls. So can one Compensation of dynamic forces done. With fixed offset angle of 180 ° and linear arrangement of the cylinders is for all production rates, i. H. Angular velocities, destructive interference before, without an offset angle of the Channels must be varied depending on the speed or frequency.

Particularly advantageous is the arrangement of printing cylinders simple scope for printed products smaller and / or variable page size and / or for printers with limited space. Compared to the production of the same product a double-circumference press (without collecting) is not a "double" Plate change required. Unlike a double-circumference printing press in collective mode, it becomes possible to create a page jump from two sides, and thereby producing increased flexibility in the printed product.

The construction of all printing cylinders with a simple scope can be compared to Printing units which have one or more double-circumference cylinders much more compact and lighter construction too. Also are damaged to be replaced blankets smaller and thus cheaper

The use of blankets and printing plates allows the cylinders on both sides Stable to store, with a simple, robust and cost-effective design of the Printing cylinder receiving side frame is possible.

Also, it is advantageous in terms of a robust and simple construction, if to Anund Turning off the printing unit only the transfer cylinders are moved have to. Although the form cylinder can for the purpose of adjustment at a distance to the assigned Transfer cylinder and possibly color and, if available, dampening changeable be stored, an on and off the transfer cylinder from each other and from the assigned form cylinders, however, advantageously takes place solely by means of a Movement of the transfer cylinder.

By a specially selected in the area of the pressure point movement is the linear Arrangement of the cylinder allows and at the same time on and off devices or Movements of the form cylinder avoided. This also contributes to the robust and simple Execution at.

In one embodiment, the transfer cylinders are, for example, in carriages in Linear guides mounted in or on the side frame, which movement in the essentially perpendicular to the plane of the cylinder axes. Are the guides on arranged specially designed inserts of the side frame, so shorten the Spigots and allow easy formation of an encapsulated lubricant space. A special arrangement of the direction of movement allows fast and safe Parking of form and impression cylinder as well as of the web.

In another embodiment, the transfer cylinders are for this purpose in levers arranged, which are mounted eccentrically to the forme cylinder axis pivotally. By the special position of the pivot points and the size of the eccentric (to the axis of rotation the forme cylinder) in conjunction with the selected inclination to the plane of the Pressure point forming cylinder or between the web and plane of the cylinder is a Quick shutdown of the associated cylinders or exemptions of the web possible. The operational starting and stopping takes place only by means of the transfer cylinder, in a preferred embodiment by means of only one adjusting movement.

In a third embodiment, the transfer cylinders are in double eccentric bushings stored, which at least in the area near the pressure point a nearly linear and allows largely perpendicular to the plane of the cylinder axes movement.

Due to the so-called. Metal blankets running lifts on the Transfer cylinders, the effective channel width is reduced, causing the excitation advantageously further reduced by vibrations and the non-printing area on the cylinders, d. H. the "white border" on the product or the paper waste is reduced.

Particularly advantageous is the one embodiment of the printing unit with cylinders simple Circumference and arrangement in one plane, with staggered, but mutually rolling on each other channels, and designed as metal blankets elevators on the transfer cylinders.

In particular, for washing, change of elevators, etc. have cylinders or rollers in printing units from the operating condition "pressure on", d. H. a pressure on position off and on again. The necessary radial movement The roll also contains a component of motion in the tangential direction, whose Size of the structural design (eccentric, lever, linear guide, and their Angle to Nippstelle) of the adjusting device depends. Arises by the adjustment in Regarding the operating condition a speed difference on the effective Lateral surfaces in the nip, this implies due to the surface friction of the Roll materials used a tangential Reibkraftkomponente which the Adjusting movement is opposite. The adjustment is thus thus inhibited or their speed is limited. This is especially true Printing cylinders in the case of so-called. "Winders" important because here from the high occurring pressures also result in large frictional forces.

Therefore, it is advantageous in a method for turning on and off of cylinders, a relative tangential velocity in the near-contact region, d. H. around Nip point of two cooperating cylinders or rollers, by conscious, with the Motion correlated rotation or rotation of at least one of the participating cylinders or rolls is reduced. In addition to a reduction of the inhibition in the adjustment is also an unnecessarily high load (friction, deformation) of the lifts and / or the The lateral surfaces of the cylinders or rollers involved avoided.

Embodiments of the invention are illustrated in the drawings and are in described in more detail below.

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 associated second cylinder 03, z. B. a transfer cylinder 03, on (Fig. 1). In a print on position AN, their axes of rotation define R02; R03 is a level E.

The forme cylinder 02 and the transfer cylinder 03 have on their circumference in Circumferential direction on the lateral surface at least one fault, z. B. an interruption 04; 06 in the effective at unwinding lateral surface. This interruption 04; 06 can an impact of a leading and a trailing end of one or more Lifts be, for example, by magnetic force or cohesively on the Scope are arranged. It may, however, also, as in the following in the Embodiments shown to channels 04; 06 or slots 04; Act 06, which pick up the ends of elevators. The following as channels 04; 06 designated disturbances are synonymous with other interruptions 04; 06 on the effective lateral surface, d. H. the outward-facing surface of the lifts 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.) on. These two channels 04; 06 are each in Longitudinal direction of the cylinder 02; 03 in a row, and in the circumferential direction to each other staggered.

Do the cylinders 02; 03 only a length L02; L03 on which essentially corresponds to two widths of a newspaper page, so only two to each other in Circumferentially offset and longitudinally successively arranged channels 04; 06 arranged.

The channels 04; 06 are so on the two cylinders 02; 03 arranged that they are at Rotation of the two cylinders 02; 03 each on one of the channels 06; 04 of each another cylinder 03; 04 unroll. Preferably, the offset of the channels 04; 06 each cylinder 02; 03 in the circumferential direction about 180 °. Thus, each roll to 180 ° Rotation of the cylinder 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 unroll.

The transfer cylinder 01 of the first printing unit 01 forms with a third cylinder 07; over a train 08; z. B. a printing substrate 08, a pressure point 09. This third Cylinder 07 can as a second transfer cylinder 07 (Fig. 1) or as a Impression cylinder 07 (FIG. 2), e.g. B. steel cylinder, or satellite cylinder 07th be executed. The axes of rotation R03 and R07 of the pressure point 09 forming Cylinder 03; 07 clamp in a pressure-on position AN a plane D (see, for example, Fig. 6 or 13).

In the embodiment of Figure 5 are the axes of rotation R02; R03; R07 of the three co-acting cylinder 02; 03; 07 during a pressure on position ON in essentially in a common level E, which in this case corresponds to the level D coincides, and parallel to each other (see Fig. 5, 12). Does the Satellite cylinder 07 on its circumference two pressure points, so is preferably a second, not shown, printing unit also in the common plane E arranged. However, it can also define its own level E, which is also defined by the their assigned level D is different.

As shown in the embodiment of FIG. 1, acts as the second Transfer cylinder 07 running third cylinder 07 with a fourth cylinder 11, in particular a second forme cylinder 11 having an axis of rotation R11, together, and forms a second printing unit 12. The two printing units 01; 12 form one on each Pages simultaneously on the web 08 printing unit 13, a so-called. Double printing 13th

In Fig. 5 are all rotation axis R02; R03; R07; R11 of the four cylinders 02; 03; 07; 11 during printing, d. H. in the print-on position AN in the common plane E or D and run parallel to each other. Fig. 6 and 13 shows a corresponding Printing unit 13, wherein in each case a pair of forming and transfer cylinders 02, 03; 11, 07 a plane E, and the transfer cylinder 03; 07 different from the E planes 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 the above for the first printing unit 01 described Characteristics regarding the number and the offset to each other. The channels 04; 06 the four cylinders 02; 03; 07; 11 are now preferably arranged so that in each case two Channels 04; 06 two cooperating cylinder 02; 03; 07; 11 roll on each other.

The forme cylinder 02 and the transfer cylinder 03 have an advantageous embodiment each a length L02; L03 on which four or more widths of a printed page, z. B. a newspaper page, z. B. 1100 to 1800 mm, in particular 1500 to 1700 mm and a diameter D02; D03, z. B. 130 to 200 mm, in particular. 145 to 185 mm, whose circumference U corresponds substantially to a length of a newspaper page, in following "single circumference" (Figures 3 and 4). Also for other sizes is the device advantageous in which the ratio between diameter D02; D03 and length L02; L03 of the cylinder 02; 03 is 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 which each extend continuously over at least one length, which two Widths of a newspaper page corresponds (Fig. 3).

It can per cylinder 02; 03 but also more than two channels 04; 06 be arranged. In this case, two channels 04; 06 in a flight, or in each case be arranged alternately. It can, however for example, four channels 04; 06 the two the end faces of the cylinder 02; 03 adjacent channels 04; 06 in a joint escape, and the two "inside" lying channels 04; 06 in a joint flight, but in the circumferential direction offset from the former (FIG. 4).

Are the interruptions 04; 06 actually as channels 04; 06 or slots 04; 06 executed, as shown schematically in Figures 1 to 4 channels 04; 06 something be longer than the width or double width of the printed page. Possibly. can two in Longitudinally adjacent channels 04; 06 also slightly in the circumferential direction overlap. This is not the only schematically illustrated Figures 1 to 4 removed in such detail.

Particularly advantageous in terms of the excitation or damping of Channel shock induced vibrations is when the channels 04; 06 on the respective cylinder 02; 03; 07; 11 are offset by 180 ° to each other. That's how they roll Channels 04; 06 between the forme cylinders 02; 11 and the transfer cylinders 03; 07 the two printing units 01; 12 at the same time and in the same section in Longitudinal direction of the cylinder 02; 03; 07; 11 off; z. B. on the same page, z. B. a page 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 more than two channels 04; 06 per cylinder 02; 03; 07; 11, for example in the region of the center of the cylinder 02; 03; 07; 11th

Due to the staggered arrangement of the channels 04; 06 and the unrolling 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 unwinding at the two printing units 01; 12 a destructive interference of the suggestions takes place, which in the choice of the Offset of the 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 running, so they are in an advantageous embodiment with a gap of small width, z. B. less than or equal to 3 mm, in the region of a lateral surface of the forme cylinder 02; 11 or transfer cylinder 03; 07 executed, which ends of one or more elevators, z. B. one or several blankets, on the transfer cylinder 03; 07 or ends of one or several elevators, z. B. one or more printing plates on the forme cylinder 02; 11 receives. The elevator on the transfer cylinder 03; 07 is preferably as so-called. Metal printing cloth running on a metallic base plate having ink-carrying coating. The folded ends are in the case of Transfer cylinders 03; 07 for example by clamping and / or clamping 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, a single, continuous Clamping and / or clamping device or it can - in the case of several Newspaper page widths through channels - in the longitudinal direction one behind the other Clamping and / or clamping devices may be arranged. The channels 04 of the forme cylinder For example, 02 also each have a single, or more Clamping devices on.

Preferably, both in the channels 04 of the forme cylinder 02; 11 as well as in the Channels 06 of the transfer cylinder 03; 07 used a "minigap technology", being in a narrow channel 04; 06 with inclined leading edge leading end inserted, the elevator on the cylinder 02; 03; 07; 11 wound up is, the trailing end also in the channel 04; 06 is inserted, and the Ends against slipping, z. B. by means of a rotatable spindle or a 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 designed as a metal blanket elevator of the transfer cylinder 03; 07 as narrow slot 04; 06 executed channel 04; 06 arranged without clamping device be, which receives the ends of the lifts. The ends are here, for example by their shape and / or the geometry of the slot in the slot 04; 06 held.

The transfer cylinder 03; 07 have z. B. in an advantageous embodiment (FIG. 3) only two, circumferentially offset by 180 ° to each other elevators, which each have at least one width, which two widths of a newspaper pages equivalent. In this case, the elevators or channels 04 of the forme cylinder 02 run; 11 Complementary to this and must either, as shown, two continuous, respectively a length of two newspaper page widths having channels 04, or in pairs adjacent and aligned channels 04, each with a length of one Have newspaper page width. In the former case, each actually has channel 04 executed interruption 04 of the forme cylinder 02; 11 in an advantageous embodiment two Clamping devices each have a length which is substantially one width of a Newspaper page corresponds to.

The form cylinder 02; 11 are in an advantageous embodiment with four in the longitudinal direction of Forme cylinder 02; 11 juxtaposed bendable elevators occupied, which in Circumferential direction a length of slightly over the length of the printed image of a Newspaper page, and in the longitudinal direction have a width of about one newspaper page. In the arrangement of continuous channels 04 and only one clamping device per channel 04; 06, which has a length of two widths of a newspaper page, so it is possible elevators with a width of two newspaper pages, so-called panoramic printing plates, raise.

For printing units 01; 12, for which a need of setting up with panoramic printing plates can be excluded, can also be an arrangement of advantage, the each to the side I and the adjacent to the side II "externa ßeren" elevators with each other and the "inner" elevators are aligned with each other and the former 180 ° are arranged offset (Fig.4). This highly symmetrical arrangement leaves In addition, reduce the risk of vibration excitation in the plane E or avoid, which is due to the non-simultaneous passage of the channels 04; 06 on Page I and page II. Also mutually on page I and page II alternately tensioning and relaxing the web 08, and thereby causing it Swinging the web 08 can be avoided.

The said arrangement of the 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 Cylinder 02; 03; 07; 11 are in development also particularly on cylinder 02; 03; 07; 11 to apply, which has a length L02; L03, which is essentially the six times the width of a newspaper page. This can be an advantage be, the transfer cylinder 03; 07 and / or the forme cylinder 02; 11 with one Diameter D02; D03 to perform, which has a scope in the substantially twice the length of a newspaper page.

For a technically simple and robust execution of the double printing unit 13, the Forme cylinder 02; 11 in an advantageous embodiment with respect to their axes of rotation R02; R11 firmly arranged. To turn on and off 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 cooperating transfer cylinder 03; 07 abstellbar, or adjusable to this. In This version are in normal operation of the printing press only the Transfer cylinder 03; 07 moves while the forme cylinder 02; 11 in their fixed, possibly remain previously adjusted position. For the purpose of adjustment, the forme cylinder 02; 11 however in corresponding devices, eg. B. in eccentric or Doppelexzenterbuchsen, in Linear guides or levers to be stored.

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

In another embodiment, not shown, the travel 16; 17 by the Storage of the transfer cylinder 03; 07 in eccentric bushes, not shown, especially in double eccentric bushings. With double eccentric bushes can be in the area of the pressure-on position AN a substantially linear travel 16, in the of the Pressure point 09 more distant range, however, if necessary, a curved travel 17th generate, which a faster or greater shutdown of the transfer cylinder 03; 07 from the cooperating transfer cylinder 07; 03 as from the assigned Forme cylinder 02; 11 or vice versa. Also for the use of eccentrics is the storage on page I and on page II of the double printing 13 advantage.

In the following (Figures 5 to 11) are embodiments of the printing unit 01; 12 set forth, wherein at least one of the transfer cylinder 03; 07 along a linear Travel path 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 in Fig. 5 also not shown side frame.

The bearings in a linear guide are made for the robust and low-vibration Construction preferably on page I and on page II of the double printing unit 13.

In Fig. 5, the course of the web 08 is located by the in-pressure ON position Print point 09 shown. The plane E of the double printing unit 13 (FIG. 5) or of the respective printing unit 01; 12 (FIG. 6) and the plane of the web 08 intersect in FIG advantageous embodiment at an angle α of 70 ° to 85 °. Assign that Transfer cylinder 03; 07 on a circumference, which is the length of about one Newspaper page corresponds, so the angle α z. B. about 75 ° to 80 °, preferably about 77 °; have the transfer cylinder 03; 07 but on a circumference, which in about the Length of two newspaper pages corresponds, so the angle α z.

B. linear bearing 34, in particular arranged a linear movement enabling rolling bearing cages 34.

The two parts of the two guides 26 leave a motion in the ideal state of the carriage 24 with only one degree of freedom as a linear movement. For this is the entire arrangement in a direction perpendicular to the axis of rotation R03; R07 and perpendicular to Movement direction of the carriage 24 lying direction against each other substantially tensioned free of play. Thus, for example, the respective formzylindernahe part of the leadership (In Fig. 9 with larger size) on a tensioning device, not shown.

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

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

The arranged on the carriage 24 parts of the guides 26 so include the carrier 36, or the parts arranged on the carrier 36, on the side frame 20 or on the bell 28 the guides 26.

The carriage 24 is articulated via a coupling 37 with a lever 38 connected, which about a substantially parallel to the axis of rotation R03; R07 the transfer cylinder 03; 07 extending axis is pivotable. in the Embodiment are for synchronizing the adjusting movement of both Transfer cylinder 03; 07, the coupling 37 of the two adjacent carriages 24 for cooperating transfer cylinder 03; 07 with the here as three-armed lever 39 executed lever 38 hinged. The drive of the lever 38 takes place by means of at least one actuator 39, z. By means of one or by means of two (as in FIG. 10) Cylinder 39 which can be acted upon with pressure medium. When operating the actuator 39 and Pivoting the lever 38 in one direction (clockwise here), the both transfer cylinders 03; 07 with their axes of rotation R03; R07 into the level E brought, while at the same time to each other and to the respective forme cylinder 02; 11 be employed. By pivoting in the other direction is the parking of the Transfer cylinder 03; 07 from each other and from the associated form cylinders 02; 11th

In particular, for the case that the actuator 39 as acted upon with pressure medium Cylinder 39 is executed, the arrangement of stops 41 is advantageous against which the respective carriage 24 is set in the pressure-on position AN. These attacks are made adjustable to adjust the end position for the transfer cylinder 03; 07 to allow in which their axes of rotation R03; R07 lie in the plane E come. The system becomes very stiff when the carriage 24 against the stop 41, or the stoppers 41 (in each case two in FIG. 10) is pressed with great force.

Are, as in the present case, the carriage 24 of the two adjacent Transfer cylinder 03; 07 put over a common adjusting means, so it is in Development of the embodiments of advantage when the actuating means between the respective carriage 24 and the first common part of the actuating means at least in narrow limits is compliant.

B. a synchronous shaft 43, with the on both sides of the Transfer cylinder 03; 07 arranged adjusting means in connection. To this end In the example, the shaft 43 with the two, one side frame 20 on page I and II associated levers 38 rotatably connected. This represents here the same time Swivel axis for the lever 38.

For the embodiments of Figures 8 to 11 may be an adjustment be provided, which, in particular during assembly and / or when Configurations and / or conditions have changed, a default setting for the Spacings of the axis of rotation R02; R03; R07; R11 allows. For this purpose, individual the cylinder 02; 03; 07; 11, z. B. the forme cylinder 02; 11, possibly in an eccentric bushing be stored. Also, at least one of the transfer cylinder 03; 07 can to Adjustment be adjustable in a radial direction. For example, the Side frame 20 and the bell 28 associated parts of the linear guides 26 or Carrier 36 in sufficient for adjustment purposes oblong holes with the side frame 20th or the bell 28 may be connected. Also an eccentric and lockable storage the radial bearing 27 in the carriage 24 is possible.

The lubricant spaces thus generated are spatially limited and prevent the pollution of adjacent machine parts and contribute to Increasing the quality of the product. In the case of using the bell 28 (Fig. 11) the transmission between the forming and transfer cylinders 02, 03; 07, 11 in the cavity 29 arranged, and be encapsulated as a lubricant space to the outside.

However, it is generally considered to be single or pairwise regardless of the design Powered cylinder 02; 03; 07; 11 of advantage, the drive units each specifically encapsulated, d. H. to run with its own lubricant space. An o. G. individual encapsulation extends, for example, to the pairwise drive of two Cylinder 02, 03; 11, 07 or else - especially in the case of the bell described above 28 - around both pairs. A bell 28 may also each be for a pair of two cylinders 02; 03; 07; 11 executed. The latter is, for example, in the sense of a Modularization of advantage.

In development of the embodiments, it is advantageous, although the respective form cylinder 02; 11 associated inking unit 21 and, if available, the associated dampening unit 22 of one, from the drive of the printing cylinder independent drive motor is rotationally driven. In particular, that can Inking unit 21 and any existing dampening unit 22 each have their own Drive motor have. It may in the case of Aniloxfarbwerks 21 the anilox roller, and In the case of a roller inking unit 21, the one or more distribution cylinders may or may be separate or groupwise rotationally driven. Also, the or the distribution cylinder of a Dampening units 22 can or can be driven individually or in groups in a rotary manner be.

The execution of the cylinder 02; 03; 07; 11 double-width and - at least the forme cylinder 02; 11 - with "single circumference" allows in contrast to printing machines with double Scope and simple width significantly higher product variability. The maximal Although the number of possible print pages is the same, in the case of single widths Printing units 01; 12 double circumference in collective operation in two different "Books" or "stapling". In the present case, the double-wide printing units 01; 12 simple extent, the (double width) tracks 08 after printing along cut. To achieve a maximum stitching strength will be one or more Partial webs in the so-called. Falzoberbau or turning tail over each other and z. B. on a folder without collecting operation folded into a booklet. Are such stapling strengths not required, some partial webs can be superimposed, others, however be performed together on a second hopper and / or folder. It can but also two products of the same strength without transfer to two folders led. A variable strength of two different products is thus given. Are in the case of a double folder or two folders at least two Depending on the order, the two booklets or Products side by side or on top of each other to one side of the printing press, or to the be led on both different sides.

A high variability has the double-width printing machine simple scope especially in the gradation of possible page numbers in the product, in the so-called. "Escapade". While the thickness per booklet (lay) for the printing machine with double Scope and simple width in collective operation (ie maximum product strength) only can be varied in steps of four printed pages, leaves the double-width described Printing machine simple circumference an "infidelity" from two sides (eg Newsprint) too. The product strength and in particular the "distribution" of the printed pages to different folders of the total product or products is considerably more flexible.

After the web 08 is cut longitudinally, the partial web is thus either on a to the corresponding part web different former and / or folder led, or she is turned on the flight of the latter. Ie. in the second Case will be the sub-web before, during or after turning but before merging with the "straight lines", brought into the correct longitudinal or cutting register. This is in dependence of circumferentially offset channels 04; 06 one Cylinder 02; 03; 07; 11 in an advantageous embodiment by corresponding embodiment of Turning corners (eg preset distances of the bars or the path sections) considered. The fine adjustment or regulation is with the positioning of the Cut register control for the relevant partial web and / or partial web strand made to partial webs of two different levels if necessary match each other.
