Description

The invention relates to a printing unit of a rotary printing press according to the preamble of claim 1.

From the WO 01/39974 A2 is a printing unit of a rotary printing press, in which the transfer cylinder has at least two in the longitudinal direction, ie seen in the axial direction of the transfer cylinder through channels. This creates a plurality of possibilities for the arrangement of elevators, for example blankets on the transfer cylinder. For double-wide pairs of cylinders with a transfer cylinder having a double circumference, several blankets are optionally circumferentially one behind the other and / or in the longitudinal direction next to each other or a channel at least partially covering and arranged continuously over the full circumference. This is to avoid that the transfer cylinder must be replaced with changing requirements of the respective format to be printed.

From the WO 2005/105447 A1 a web-fed rotary printing press is known, which is designed for printing substrate webs of different widths, wherein the respective different widths are provided by respectively different product formats, e.g. B. newspaper formats are conditional.

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

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular that different widths of substrate webs or different widths partial webs of the printing substrate webs can be printed without replacing the transfer cylinder in different modes of operation of the printing unit.

In particular, in one mode, newspaper pages of a particular format and in another mode, newspaper pages of a different format, or other printed products, such as magazines, may be printed.

A particularly preferred solution variant results when the transfer cylinder has a plurality of circumferentially offset channels for receiving at least one elevator, in particular a blanket, which extend in the axial direction of the transfer cylinder only over a partial length of the transfer cylinder, which seen in the axial direction adjacent channels preferably partially overlap in the axial direction. As a result, printing blankets can be arranged at different axial positions of the transfer cylinder in a structurally simple manner or blankets of different widths can be arranged at the corresponding or else at different axial positions of the transfer cylinder.

A further particularly preferred solution variant results according to an alternative embodiment, when the transfer cylinder has at least one channel for receiving the blankets, which extends in the axial direction of the transfer cylinder over at least substantially the entire length of the transfer cylinder, wherein the transfer cylinder in different modes of operation at least printing blankets partially different format. Also in this case can be arranged at different axial positions of the transfer cylinder printing blankets or different widths at the corresponding or at different axial positions of the Transfer cylinder can be arranged.

A further, particularly preferred solution variant results according to another alternative embodiment, when the transfer cylinder has at least two channels for receiving the blankets, which extend in the axial direction of the transfer cylinder over at least substantially the entire length of the transfer cylinder. Also in this case blankets can be arranged at different axial positions of the transfer cylinder in a structurally simple manner or blankets of different widths are arranged at the corresponding or at different axial positions of the transfer cylinder. In this solution variant, for example, a newspaper printing in variable web widths, a retail production and printing with panoramic printing forms are possible using one and the same transfer cylinder.

In a printing press not shown here, in particular rotary printing press one or more printing units 01 are arranged. The rotary printing machine can be, for example, a web-fed rotary printing press of a type known per se, in particular a newspaper printing machine which can have a plurality of printing towers, each with, for example, three-width printing units consisting of at least two printing units 01, d. H. designed for the printing of six printing pages arranged side by side in the axial direction. The individual printing units can be configured as satellite printing units, for example as nine-cylinder satellite printing units, or as printing units which can be operated in rubber-against-rubber printing, such as printing units. B. bridge printing units or H-printing units.

The printing unit 01 and the printing units 01 of the rotary printing machine webs 02 or printing material 02, for example, supplied paper webs 02 of rollers, not shown, for example, in a conventional manner on reel changer, and the printing material 02 can after passing through the printing units 01 a superstructure of Towers are fed, in which they z. B. cut on slitters and sub-webs possibly offset and / or are overthrown and ultimately either as a strand or as multiple strands can be fed to a folding structure.

The printing unit 01 comprises a printing cylinder 03, z. B. a forme cylinder 03, a printing cylinder 04, z. B. a transfer cylinder 04 and a printing cylinder 06, z. B. a counter-pressure cylinder 06, see. for example Fig. 1 , The printing substrate 02 is guided between the transfer cylinder 04 and the impression cylinder 06 and the transfer cylinder 04 forms with the an abutment performing impression cylinder 06 a pressure point. The impression cylinder 06 may be a satellite cylinder 06 of a satellite printing unit or a transfer cylinder 06 another, cooperating with the printing unit 01, otherwise not shown in detail printing unit 01 in a rubber-against-rubber be working pressure unit.

The printing unit 01 may be, for example, as a working in wet offset printing unit 01 and accordingly, the inking unit 03 may be associated with the forme cylinder 03 in a known per se and therefore not shown manner, an inking unit and a dampening unit. The forme cylinder 03 can be assigned to at least one elevator 07, for example a printing forme 07, and the transfer cylinder 04 can be assigned to at least one elevator 08, for example a blanket 08.

The printing unit 01 can be followed for certain applications, one or more, not shown drying equipment, wherein in one mode, the printing substrate 02 is passed through the drying device and in another mode, the printing substrate 02 is not passed through the drying device, the printing substrate 02 so the drying device is guided past or the drying web is moved out of the guideway of the printing material 02 out.

Depending on the requirements of the print formats and printing performance and according to the possibilities in the paper guide, the printing cylinder 03; 04; 06 different widths formed. For example, the printing cylinder 03; 04; 06 for the newspaper printing single, double or triple width, where simply the axial length of the respective bale of the corresponding printing cylinder 03; 04; 06 for two standing or lying sides, z. B. newspaper pages. In commercial printing, the width required for four horizontal or six vertical DIN A4 pages is referred to as double-wide. The sizes of the printing cylinder 03; 04; 06 are each carried out simply or twice, based on a wide variety of standing (broadsheet format) or horizontal (tabloid format) formats, for example, a standing or lying newspaper format. Advantageous constellations in newspaper printing are, for example, a double-sized circumference, ie two sides in the circumferential direction in the transfer cylinder 04, combined with a double or simple circumference of the forme cylinder 03, each double or triple wide.

In the case of the embodiments shown here Fig. 1 to 6 have the printing cylinder 03; 04; 06 each have twice the size and are each three times wide.

Fig. 1 shows a designed as a plate cylinder 03, occupied with printing plates 07 form cylinder 03 and a blankets 08 occupied with transfer cylinders 04. The forme cylinder 03 has two longitudinally, ie in the direction of the axis of rotation and circumferentially spaced channels 09; 11 for receiving the ends of at least one printing plate 07. The channels 09; 11 are arranged offset in the case of the embodiment in the circumferential direction by 180 ° or 90 ° and extend at least substantially over the entire axial length of the forme cylinder 03. The forme cylinder 03 is in the case of the embodiment with twelve printing plates 07 each of the same size occupied in each case six printing plates 07 in the axial direction of the forme cylinder 03 next to one another and in each case two printing plates 07 in the circumferential direction of the forme cylinder 03 are arranged one behind the other. The viewed in the axial direction width a1 of the printing plates 07 corresponds in the case of Fig. 1 the maximum possible width a1 of the printing plates 07, in which the forme cylinder 03 is covered over its entire axial length with printing plates 07 of the same format. Each printing plate 07 can each have a printed image of a stationary newspaper page, in particular broadsheet page.

The transfer cylinder 04 has three longitudinally, ie in the axial direction of the transfer cylinder 04 extending channels 12; 13; 14 for receiving the ends of each one of three blankets 08 on. Both ends of a blanket 08 are held in the case of the embodiment in each case in one and the same channel 12 or 13 and 14 respectively. The channels 12; 13; 14 extend seen in the axial direction only one Part length of the transfer cylinder 04. The channel 12 extends from an axial end of the transfer cylinder 04 away in the direction of the cylinder center over a length of more than one third of the cylinder length, but less than half the cylinder length. The channel 14 extends from the other axial end of the transfer cylinder 04 away in the direction of the cylinder center also over a length of more than one third of the cylinder length, but less than half the cylinder length. The channels 12; 13; 14 are arranged symmetrically with respect to the cylinder center. The arranged in the axial direction between the channel 12 and the channel 14 arranged central channel 13 is arranged centrally with respect to the cylinder center and has a length at least substantially equal to one third of the cylinder length. It follows that between the channel 12 and the central channel 13 on the one hand and the channel 14 and the central channel 13 on the other hand seen in the axial direction, a partial overlap of the channels 12; 13 or 14 is present. The channels 12; 14 on the one hand and the middle channel 13 on the other hand are thus unequal length, ie in the case of the embodiment, the two outer channels 12; 14 longer, for example by 10 to 30%, preferably by 15 to 25%, ie by about 20% longer than the central channel 13th

Seen in the circumferential direction, the two outer channels 12; 14 offset from the central channel 13 by 180 ° or 90 °. In operation, the respective angular positions of the forme cylinder 03 and transfer cylinder 04 are correlated with each other so that the channels 12; 14 of the transfer cylinder 04 z. B. on the channel 11 of the forme cylinder 03 and the channel 13 of the transfer cylinder 04 roll on the channel 09 of the forme cylinder 03.

In the case of the embodiment according to Fig. 1 the format of all three printing blankets 08 is at least substantially the same, ie the measured in the axial direction width b1 of each blanket 08 is equal and corresponds on the one hand at least approximately one third of the axial length of the transfer cylinder 04 and on the other hand, the width of two printing plates 07th The width b1 of the blankets 08 corresponds in the case of the Fig. 1 the maximum possible width b1 of the printing blankets 08, in which the transfer cylinder 04 is covered over its entire axial length with equally wide blankets 08. Finally, the occupied with blankets 08 length of the transfer cylinder 04 corresponds to the width c1 of the printing substrate 02. As from Fig. 1 becomes clear, the middle blanket 13 covers the inwardly directed end portions of the two outer channels 12; 14th

In the case of in Fig. 1 shown first printing of the printing unit 01, the clamped on the transfer cylinder 04 blankets 08 or blankets 08 according to the maximum printable in the printing unit 01 format all a first width b1 according to the maximum printable format.

At the in Fig. 2 shown second mode of operation of the printing unit 01 a contrast smaller, especially narrower format is printed. In this case, forme cylinder 03 and transfer cylinder 04 of the first mode of operation are basically maintained, but differently occupied compared to the first mode of operation.

Again, the forme cylinder 03 is occupied for example with twelve printing plates 07a, which are now however narrower than in Fig. 1 shown printing forms 07 of the first mode of operation, that is, have a width a2 which is smaller than the width a1. The twelve printing plates 07a can each again z. B. have a printed image of a newspaper page standing, but now is narrower than in the case of the first mode of operation. The twelve printing plates 07a are arranged adjacent to one another on the forme cylinder 03, so that the two end sections of the bale of the forme cylinder 03 remain unoccupied. The occupied by printing plates 07a length of the forme cylinder 03 corresponds to the width c2 of the printing material 02 now used.

At the in Fig. 2 shown second mode of operation of the transfer cylinder 03 with three blankets 08a; 08b; 08c occupied, wherein the middle blanket 08b the two associated with middle printing plates 07a and the width b2 of the middle blanket 08b correspondingly corresponds to the width of two printing plates 07a. Immediately adjacent to the middle blanket 08b a blanket 08a and 08c is arranged on both sides, the width b3 is at least equal to the width b2 of the middle blanket 08b, in the case of the embodiment shown here, however, wider than this and also wider than the blankets 08th is and can extend to the respective associated axial end of the transfer cylinder 04.

In the alternative and preferred embodiment of the second mode of operation Fig. 3 , moreover, according to those of Fig. 2 corresponds, the transfer cylinder 04 is occupied with three blankets 08b each having the same width b2. From the above, it is clear that the two outer blankets 08a and 08c can basically each have a width which is between the width b2 of the middle blanket 08b and the width b3 according to FIG Fig. 2 lies.

How out Fig. 2 and 3 becomes clear, covers the blanket 08b in the second mode of operation, in contrast to the first mode of operation, the two outer channels 12; 14 of the transfer cylinder 04 is no longer. The two outer blankets 08a; 08c ( Fig. 2 ) or 08b; 08b ( Fig. 3 ) are with their inner edges at the inner ends of the outer channels 12; 14 arranged and cover the channel 13 partially ( Fig. 2 and 3 ). The position of the abutting edges of adjacent blankets 08b is offset in the second mode of operation in relation to the first operation according to the narrower format inwards.

The following is with reference to 4 to 6 A second embodiment of the invention is described. The printing unit 01 shown here differs from the printing unit 01 Fig. 1 to 3 in particular in that on the transfer cylinder 04 instead of the three mutually offset channels 12; 13; 14 now a single, over the entire axial length of the transfer cylinder 04 continuous channel 16 to Receiving the ends of the blankets 08 is provided. The blankets 08 are thus not spanned in the case of this embodiment offset from each other on the transfer cylinder 04.

In the case of the first mode of operation of the second embodiment Fig. 4 extend the elevators 07 and 08 respectively over the entire axial length of the forme cylinder 03 and the transfer cylinder 04 and the printing unit 01 prints on the printing substrate 02 of the width c1 thus again the largest possible format. Regarding the details will refer to the description in connection with Fig. 1 Referenced.

In a second mode of operation of the second embodiment according to Fig. 5 are the printing cylinder 03; 04 in turn occupied with respect to the first operation narrower elevators 07a and 08b, preferably of equal width. With the exception of the angular orientation of the two outer blankets 08b corresponds to the occupancy of those according to Fig. 3 , Also in the case of this embodiment, the two outer blankets 08b could be made wider than the middle blanket 08b, for example as wide as the two outer blankets 08a and 08c according to FIG Fig. 2 ,

According to the embodiments described above, at least one blanket 08b is thus used in the second mode of operation, whose width b2 is smaller than the width b1 of the corresponding blanket 08 in the first mode of operation.

Another approach is that in the second mode, are printed at the smaller formats, the number of blankets 08, with a corresponding broadening of the blankets 08 to achieve the required overall width, is reduced, in particular by one is reduced.

This further approach, which may possibly be combined with the first approach, is in the case of Fig. 6 selected. In the alternative training shown here the second mode of operation of the printing unit 01 according to Fig. 4 is the transfer cylinder 04 now occupied only with two blankets 08d, which are clamped in the case of the embodiment symmetrically to the center plane of the transfer cylinder 04 and adjacent to each other on the transfer cylinder 04. The width b4 of each blanket 08d is three times the width a2 of the printing forms 07a. The axial, in this case the axially central position of the joint between the two blankets 08d corresponds to the axial, in this case axially central position of the joint between the two central printing plates 07a.

The two blankets 08d could in principle be wider than in Fig. 6 shown and a maximum width corresponding to half the axial length of the bales of the printing cylinder 03; 04; 06 have. Preferably, both blankets 08d have the same width.

While according to the above embodiments, the forme cylinder 03 with elevators 07; 07a, etc. are each occupied the same format, in a manner not shown here also assignments with different formats are possible, as will be explained below with reference to some examples. Likewise, it is not necessary that the elevators 07; 07a, etc. are always symmetrically arranged with respect to a press center axis, in particular applications asymmetrical arrangements of the printing plates or printed images may be appropriate, cf. also below.

The following will be on FIGS. 7 and 8 Referenced. Insofar as reference is made in this connection to the elevators 07 and 08 according to the first mode of operation, the corresponding situation also applies to the elevators 07a; 08a; 08b; 08c and 08d of the second mode of operation.

Elevators 07; 08 on forming and transfer cylinder 03; 04 of the printing unit 01 are as in Fig. 7 shown schematically preferably designed as flexible plates, wherein the elevator 08 (preferably a multilayer blanket 08, eg a so-called metal blanket 08) designed as a blanket 08 is designed with an elastic and / or compressible layer 22 (dashed) arranged on a dimensionally stable carrier plate 23 (eg metal plate) is (in Fig. 7 are the only the metal blanket 08 concerned reference numerals connected by dashed lines). A plate-shaped printing plate 07 and a support plate 23 for a blanket 08 is usually made of a flexible, but otherwise dimensionally stable material, for. B. of an aluminum alloy, and has two opposite, in or on the printing cylinder 03; 04 to be fastened ends 24; 26 with a material thickness of z. B. 0.2 mm to 0.4 mm, preferably 0.3 mm, said ends 24; 26 for training as suspension legs 24; 26 each along a bending line with respect to the extended length I of the elevator 07; 08 at an angle α; β are bent between 40 ° and 140 °, preferably 45 °, 90 ° or 135 ° ( Figure 7 ). A leading end 24 is, for example, at an acute angle α of 40 ° to 50 °, in particular 45 °, and a trailing end 26 at an angle β of 80 ° to 100 °, in particular 90 °, folded. If in the circumferential direction of the printing cylinder 03; 04, in particular of the transfer cylinder 04, only a single elevator 08 is applied, the length I of the elevator 08 corresponds almost to the circumference of this printing cylinder 04.

Basically, the folded ends 24; 26 of elevators 07; 08 now each in a on the circumference of the respective printing cylinder 03; 04 in the longitudinal direction axially parallel, slot-shaped opening 28 can be inserted (see. Fig. 8 ), the ends 24; 26, for example, be held by their shape, friction or deformation. However, they can also be fixed in addition by means of spring force, by pressure medium or by an effective during operation centrifugal force operable means. The slot-shaped openings 28 for pressure plates 07 arranged side by side in the axial direction on the forme cylinder 03 corresponding to the channels 09; 11 (cf. Fig. 1 to 6 ) Are in an advantageous embodiment in each case in an escape, z. B. as a continuous slot-shaped opening 28, while the corresponding openings 28 for on the Transfer cylinder 04 juxtaposed blankets 08 also continuously (see. 4 to 6 ) Channel 16 or not continuously, but each other in the circumferential direction may be preferably offset by 180 ° (see. Fig. 1 to 3 ) Channels 12; 13; 14th

The following to the ends 24; 26 of the elevator 07 and to the holding device 29; 31 (cf. Fig. 8 ) in the channel 09; 11 of the forme cylinder 03 described applies in an advantageous embodiment substantially on the channel 12; 13; 14; 16 of the transfer cylinder 04 to. Therefore, in parentheses, the corresponding reference numerals in FIG Fig. 8 also cited for the transfer cylinder 04.

In an advantageous embodiment of the forme cylinder 03, as in the Fig. 1 to 6 are shown in the forme cylinder 03 two channels 09; 11 is provided, which extend continuously in the axial direction of the printing cylinder 03 in the bale. Below a lateral surface 21 in the interior of the printing cylinder 03 (04) arranged, z. B. as circular holes running channel holes 27 have a narrow, slot-shaped opening 28 to the outer surface 21 of the printing cylinder 03 (04). A slot width s28 of the opening 28 on the printing cylinder 03 (04) in the circumferential direction is less than 5 mm and is preferably in the range of 1 mm to 3 mm.

The folded ends 24; 26 of the elevator 07 (08) are now each in one of the circumferentially axially parallel openings 28 can be inserted and are, at least the trailing end 26, by a arranged in the channel bore 27 holding device 29; 31 fixable.

The holding device 29; 31 here has at least one clamping piece 29, z. B. clamping element 29 and a spring element 31 ( Fig. 8 ). The not shown right angle beveled trailing suspension legs 26 (see Fig. 7 ) preferably arrives at a wall of the opening 28 that is essentially complementary to the fold Appendix and is pressed there by the clamping piece 29 by a force exerted by the spring element 31 on the clamping piece 29 force. The acute-angled bent leading suspension leg 24 (see Fig. 7 ) preferably abuts a wall of the opening 28 that is substantially complementary to this fold and that forms a hooked edge or nose with the jacket surface 21 at an acute angle α 'of 40 ° to 50 °, in particular 45 °. To release the clamping of the trailing end 26, an adjusting means 32 is provided in the channel bore, which counteracts the force exerted by the spring element 31 on the clamping piece 29 in its operation force and the clamping piece 29 pivots away from the wall or the end 26.

In an advantageous embodiment, in each channel bore 27 of the printing cylinder 03; 04 not only a clamping piece 29, but are axially adjacent a plurality of clamping pieces 29 in the manner of segments, each with at least one spring element 31 is arranged. For example, in several sections, each one elevator 07 (08) may be assigned to each section, several, z. B. three or six, such clamping pieces 29, wherein centrally between the clamping elements 29 of each section, here between the third and the fourth clamping element 29 of each section, each a register stone can be arranged. The register stone or Passerstift z. B. in a groove of a base in the axial direction manually adjustable and adjustable. The index block can also be shown in an unillustrated development via an axially guided in a freely remaining cavity of the channel bore 27 and the fitting element actuation device, for. B. a motor-driven threaded spindle, be axially movable.

The adjusting means 32 is designed in the illustrated embodiment for the forme cylinder 03 such that when actuated the holding device (s) 29; 31, ie all the clamping pieces 29 are closed or solved simultaneously over the length of the sections. In the case of the transfer cylinder 04 this applies to holding device (s) 29; 31 of the The adjusting means 32 is in this case for the forme cylinder 03 than at least over the length of the sections provided there, and extending for the transfer cylinder 04 as at least over the length of the sections provided here, extending in the channel bore 27 and with pressure medium operable reversibly deformable hollow body 32, z. B. as a hose 32, executed. This hose 32 is according to Fig. 8 with the clamping pieces 29 acting together in the channel bore 27 so arranged that he the self-locking the holding device 29; 31 counteracts closing spring elements 31 when actuated. He is then passed through the areas of possibly existing passer elements.

As can be seen from the comments related to Fig. 1 to 6 results, the printing unit having 01 printing press is able, without replacing the transfer cylinder 04 two (or more) different formats F1; F2, where F1 is the larger (wider) format. The corresponding widths of the respective associated printing material web 02 are c1 and c2. The respective printing substrate 02 is optionally cut into partial webs after printing and fed to a folding structure 33. In Fig. 9 are two different web widths c1 and c2 of the printing substrate 02 together with a folding structure 33 shown schematically. Also, an imaginary printing machine center axis M is indicated. In the Fig. 9 not shown) elevators 07; 07a; 08; 08a; 08b; 08c; 08d are preferably arranged symmetrically to this printing press center axis M. The printing substrate 02 passes through the printing units 01 regardless of the width c1; c2 also preferably symmetrical to this printing press center axis M.

The folding structure 33 comprises in the case of the embodiment according to Fig. 9 three juxtaposed former 41; 42; 43, corresponding to three from the printing substrate 02 to be cut (not shown here) partial webs, the funnel tip of the central former 42 on the printing machine center axis M is arranged. The positions of the two outer formers 41; 43 is, as indicated by the double arrows, variable to the respective format F1; F2 or the assigned width c1; c2 be adapted to the printing substrate 02 or the partial webs produced therefrom.

In the 10 and 11 are schematically advantageous occupancies and configurations of elevators 07; 08 etc. for a wider substrate web 02 ( Fig. 10 ) and for a narrower printing substrate 02 ( Fig. 11 ). The elevators 07 shown; 08 etc., however, do not correspond to a top view, but rather a complete development of the respective printing cylinder 03; 04. The arrangement after Fig. 10 corresponds to the first embodiment according to Fig. 1 in the first mode of operation and the arrangement according to Fig. 11 according to the first embodiment Fig. 2 in the second mode of operation.

As well as z. In Fig. 1 shown, all (here twelve) printing plates 07 can be formed and arranged as a single printing forms. However, it is also possible to use combinations of individual printing forms and larger-format printing forms, eg. B. panoramic printing plates 07b rest, as in Fig. 10 illustrated by an example right below, which then, for example, twice the width of the width a1 of the printing plates 07 have.

Fig. 12 shows a variant too Fig. 11 , ie the second mode of operation with the narrower format F2, wherein the forme cylinder 03 in addition to printing plates 07a of the smaller size F2 and also printing plates 07c a larger width with the format F3, z. B. can carry twice the width.

Fig. 13 shows a further variant in which the forme cylinder 03 is occupied at its one (left) half with the printing plates 07a of the format F2 and at its other (right) half asymmetrically with printing plates 07d; 07a; 07e each different Formats F4; F2 or F5. Accordingly, partial webs 02a; 02b; 02c cut with different widths c2a; c2b or c2c. The corresponding cutting lines S1; S2 are not symmetrical to the printing press center axis M. At least one of the three formers 41; 42; 43 (here at 42 and 43), the folding plane does not coincide with the center of the associated partial web 02a; 02b and 02c (here 02b and 02c) together so that the resulting longitudinally folded sub-string 02b; 02c has unequal leg lengths. Elevators 08a; 08e; 08f all have different widths corresponding to the width c2a; c2b; c2c of the partial webs 02a; 02b and 02c on.

Fig. 6 is not shown in this figure). The forme cylinder 03 is symmetrically assigned to the printing machine center axis M as an example of an alternative assignment with eight large-format printing forms 07f of a format F5. In the illustrated second mode of operation, a central section of the printing material web 02 takes place in two partial webs 02d; 02e along the main cutting line S3, and in addition, the partial webs 02d; 02e are cut along side cutting lines S4 and S5, so that four partial trench width partial webs arise, which in the two, this second mode of operation associated with the former 42; 46 come in.

For the first mode of operation, in which the transfer cylinder 04 is occupied by three blankets 08, or for an alternative second mode of operation, in which the transfer cylinder 04 with three blankets, z. B. 08b, is another group of three formers 41; 42; 43 provided, for example, also in the printing machine center axis M above or below the from the formers 44; 46 existing group may be arranged, both groups depending on the mode of operation are alternatively controlled.

The assignment of the forme cylinder 03 with printing plates 07 can according to Fig. 15 or 17 correspond, so twelve printing plates 07, arranged in two rows on the circumference with six printing plates 07 side by side. The transfer cylinder 04 is occupied in this embodiment with two blankets 08h, each extending at least substantially over the entire axial length of the transfer cylinder 04 and over each half the circumference of the transfer cylinder 04 and the ends 24; 26 (cf. Fig. 7 ) are respectively fixed in the channels 17 and 18.

Another mode of operation of this embodiment shows Fig. 20 in connection with a double printing unit 49, wherein both pairs of cylinders 47; 48 are shown in the same occupied (which is not essential). The assignment of the transfer cylinder 04; 04 with blankets 08h corresponds to that according to Fig. 19 , the form cylinder 03; 03 are now, however, each occupied by a single printing forme 07h, which may extend at least substantially over the entire length of the respective forme cylinder 03 and which extends at least substantially over the entire circumference of the respective forme cylinder 03 and with its two ends 24; 26 (cf. Fig. 7 ) is held in one and the same channel 09 of the forme cylinder 03. The other channel 11 of the forme cylinder 03 is covered by the printing forme 07h.

A further embodiment or mode of operation of a printing unit 01 is shown in FIG Fig. 21 shown by a double printing unit 49. That in the Fig. 21 shown on the right Cylinder pair 47 has a different assignment or mode of operation than the pair of cylinders 48 shown on the left. In the case of both cylinder pairs 47; 48 or printing units 47; 48 is the respective transfer cylinder 04 with two blankets 08g occupied with a width of at least substantially corresponding to half the length of the transfer cylinder 04 and a length of at least substantially corresponding to the circumference of the transfer cylinder 04. The occupancy of the transfer cylinder 04 thus corresponds to that Fig. 15 ,

After the measured width in the axial direction of the bearer rings 51 at the forme cylinder 03 of the printing unit 47 is greater than the width of the bearer rings 52 in the forme cylinder 03 of the printing unit 48, the assignable with printing plates axial length at the printing unit 47 is smaller than the printing unit 48, or, different expressed, the width of the bearer rings 51; 52 is to be occupied with elevators 07 length of the corresponding pressure cylinder 03; 04 adapted.

The forme cylinder 03 of the printing unit 47 can be covered with a total of twelve printing plates 07 of the same format, namely in each case six printing plates 07 side by side in two rows one behind the other. The forme cylinder 03 of the printing unit 48 may also be occupied with a total of twelve printing plates 07, namely six printing plates 07 side by side in two rows one behind the other, but now have the z. B. internal printing plates 07 on the one hand and the z. On the other hand, for example, on both sides of the forme cylinder 03, two outer printing plates 07i of a larger format and between these outer printing plates 07 a total of eight internal printing plates 07 arranged.

The in connection with the embodiments according to Fig. 15 to 21 described printing units 01; 47; 48 may be designed in particular for use in web-fed rotary printing presses designed at least for, among other things, newsprint. According to a preferred embodiment, the formats used or insertable or the corresponding printing group cylinders 03; 04; 06 on a newspaper page a width of 12 "and a length of 21" tuned. A corresponding web-fed rotary printing press, which is preferably designed as a 6/2 printing press, in which therefore the printing cylinder 03; 04; 06 (at least) have a length of six pages and a circumference of two sides, therefore, must preferably be able to process a printing substrate 02 a width of 72 ".

Preferably, with the printing units 01; 46; 47 equipped web-fed rotary printing press designed so that on both sides of six times the width of a supernatant of 2 "for so-called" popups "is provided, so that in this case a total web width of 76" at a circumference of the printing cylinder 03; 04; 06 or the pressure plate (s) 07 of 42 "results.

Furthermore, preferably, the production of the with the printing units 01; 46; 47 equipped web-fed rotary press from newspaper printing to retail; This also includes odd-numbered page numbers in width and variable page widths, so that for this operation in the width (ie seen in the axial direction) continuous blanket 08h is required, as for example in Fig. 20 is shown.

The printing unit 01 (or 47, 48) according to Fig. 15 to 21 allows a variety of different operations, resulting in a very flexible printing operation. For example, the following modes of operation are possible:

According to Fig. 15 and 16 in which two half-width Ganzgegenes blankets 08g on the Transfer cylinders 04 are clamped, for example, newspaper productions with variable web width or newspaper productions on the one hand and other printed products such. B. magazines on the other hand be driven. The printing plates 07 can be 12 "printing plates.

Two other alternative modes of operation with two half-width full-circumference blankets 08g shows Fig. 21 , wherein on the forme cylinder 03 of the printing unit 47 shown on the right, twelve standard 12 "printing plates 07 for a conventional newspaper production with a width of a printing substrate 02 of 72" can be placed and on the forme cylinder 03 of the printing unit 48 shown on the left eight standard 12 " -Druckplatten 07 in the middle and two 14 "wide printing plates 07i on the sides for a production with popups, so with a width of a substrate 02 of 76".

The printing plates 07 may in turn be 12 "printing plates, the printing plates 07g (see printing unit 48 in FIG Fig. 18 ) Panoramic printing plates 07g.

According to Fig. 19 and 20 in which two full-width half-circumference blankets 08h are clamped onto the transfer cylinder 04, for example, again a newspaper production can be run with 12 "printing plates 07, cf. Fig. 19 , which can later be converted to a variable retail production, cf. Fig. 20 with printing plate 07h.

The blanket holding devices, for. B. holding devices 29; 31 (cf. Fig. 8 ) or other holding devices or closures are in a known per se and therefore not shown manner, in particular so partially formed and actuated that they can hold and tension the different widths blankets, in particular two half-width Ganzumfangs blankets 08g, three one-third full-circumference printing blankets 08 or two full-width half-circumference blankets 08h.

The in connection with the embodiments according to Fig. 15 to 21 used printing blankets 08, etc. preferably have a dimensionally stable, elastically deformable support plate 23 in particular of metal, cf. also Fig. 7 and related description, so they are preferably designed as metal blankets 08 and so on. The carrier plate 23 preferably has a thickness of at least 0.25 mm, in particular a thickness of at least 0.28 mm. In particular, even when the printing press is driven in retail mode, it is preferable to provide that the two printing blankets 08h arranged successively in the circumferential direction on the transfer cylinder 04 from the same batch or from the same batch, but in the production of the blankets 08h consecutively are cut to ensure a uniform printing operation.

The printing plates 07, etc. used may be printing plates 07 etc. with a thickness of, for example, 0.4 mm. Accordingly, the forme cylinder 03 may have an undercut for 0.4 mm thick printing plates 07, etc. For a newspaper production, broadsheet page sized half circumference plates as well as panorama plates 07g may be used. For a retail production, as stated above, very wide Ganzumfangs printing plates 07h are clamped. Here, the unoccupied and covered by the pressure plate 07h channel 11 can be left without change and without filler, since in a retail production through the second channel 17 of the transfer cylinder 04 is prevented that plate fractures arise there.

As is apparent from the above, the transfer cylinder 04 according to one aspect of the invention in the longitudinal direction in the first and / or second operation, two blankets 08g and in the circumferential direction in each case a blanket 08g on ( Figure 15 . 16 and 21 ).
