Abstract

The invention relates to a method for determining a particular position of at least one type area on a web of material to be imprinted with at least one print image in a printing press, the at least one print image being printed on a usable area of the web of material, said usable area being defined by the relevant type area, the relevant position of the at least one type area being pre-established in a section of this web of material, this section being delimited by two delimitation lines that follow in succession at a distance from one another in the direction of transport of the web of material and that are oriented transversally to the direction of transport of the web of material, the relevant section being provided with a transverse fold running parallel to these delimitation lines at a pre-established position of a fold line between the two delimitation lines of said relevant section. Several such sections that follow in succession in the direction of transport of the web of material and that are each to be provided with a transverse fold are provided. In several of these sections, the relevant position of the at least one type area that is to be pre-established between the two respective delimitation lines is pre-established by open- or closed-loop control carried out by a control unit. For at least one of multiple successive sections, an existing deviation or an expected deviation of the position of the fold line of the transverse fold from a desired position is detected by a detection device that supplies data to the control unit. The open- or closed-loop control carried out by the control unit counteracts this detected deviation in such a manner that, for each particular section in which a deviation has been detected and/or for at least one section which follows this section, a relative position, which existed prior to this detected deviation, of the type area that is to be pre-established in the relevant section is restored to the desired position of the fold line of the transverse fold while taking into account a tolerance range which applies to this relative position.

Fig. 1 shows a section of a material web 01, z. As a paper web, in a printing machine, for. B. in a web press, especially in one

Web-fed rotary printing press, by means of at least one printing unit this

Printing machine consecutively sections with at least one print image 02, z. B. with a text or a graphic or an image, preferably in a tabloid production is printed. The tabloid production concerns a production format in which z. B. text lines of the print image 02, which in each case by z. Three parallel lines are indicated, at least in their main

Orientation in each case in the transport direction T of the web 01 extend. The at least one of the at least one printing unit printed on the web 01 print image 02 is within an i. d. R. rectangular sentence mirror 03 arranged. The type area 03 defines a usable area available for the at least one print image 02, wherein subsequently the position of the type area 03 is considered only with reference to the material web 01 to be provided with the at least one print image 02. The type area 03 is usually at all its i. d. R. four straight edges 04; 06; 07; 08 through bars 09; 1 1; 12; 13 limited, each web 09; 1 1; 12; 13 an i. d. R. unprinted distance a09; a1 1; a12; a13 between one of the edges 04; 06; 07; 08 of the type area 03 and a respective edge 04; 06; 07; 08 nearest boundary line 14; 16; 17; 18 of the respective type mirror 03 receiving portion 19 of the material web 01 forms, said portion 19 in

Transport direction T of the web moved by the printing press 01 has a constant length a19 at least for a specific production executed by the relevant printing press. In a continuous from the printing press

Therefore, a plurality of such sections 19 are lined up seamlessly. Two of the boundary lines 16; 18 are aligned parallel and in each case longitudinally to the transport direction T of the material web 01 and limit the respective section 19 through the respective edge of the material web 01st Two others

Boundary lines 14; 17 are also parallel, but each directed transversely to the transport direction T of the web of material 01 and limit the respective section 19 respectively in the transport direction T of the material web 01st In the following it is assumed that each of a section 19 limiting positions of each transverse to

Transport direction T of the web 01 directed boundary lines 14; 17 are not changed in their respective distance from each other and thus the respective length a19 in the same production of successive sections 19 remains the same. By a successive at least along one of these in the transport direction T of the web of material 01 at a distance of length a19, transversely to the transport direction T of this Web 01 directed boundary lines 14; 17 executed separation process is the relevant of the boundary lines 14; 17 limited section 19 separated from the web 01. The separation process is carried out in particular in one of the printing machine associated folding apparatus 32 and consists for. In a cutting process wherein a cutting blade 41 arranged on a cutting cylinder 33 rotating during the production of the press concerned continuously sequentially separates one section 19 from the web 01 (FIG. 5). The along the transversely to the transport direction T of the web 01 directed boundary lines 14; 17 with the cutting blade 41 of the cutting cylinder 33 executed separation process is shown in Figure 1 by a these boundary lines 14; 17 respectively associated scissors symbol indicated. It is provided that preferably each separated from the web of material 01 section 19 at one between its two transverse to the transport direction T of the web of material 01 boundary lines 14; 17 fixed position with a parallel to these boundary lines 14; 17 extending transverse fold is provided, said transverse fold is indicated in Fig. 1 by the position of its fold line 21. The Querfalzung, ie the formation of a fold break along this fold line 21, takes place in a sequence of the production process after the executed separation process with a Querfalzeinrichtung preferably also in the folder 32nd

The proposed solution provides that the relevant position of the at least one directed between the two transverse to the transport direction T of the web 01 boundary lines 14; 17 set masking level 03 relative to the position of the between the two boundary lines 14; 17 transverse fold to be arranged, d. H. to its fold line 21, is set. When the position of the fold line 21 of the

Querfalzes changes, so should in dependence on this change in position in the relevant section 19 and the position of the at least one of the two above, this section 19 delimiting boundary lines 14; 17

arranged set mirror 03 can be changed, so that the position of the type area mirror 03 with respect to the position of belonging to this section 19 fold line 21 of the transverse fold remains unchanged.

This is illustrated by FIG. 2. Fig. 2 shows how Fig. 1 a web of material 01, which is continuously printed in sections in its transport direction T. The respective section 19 limiting, transverse to the transport direction T of the web 01 directed boundary lines 14; 17 are unchanged in their respective position in Fig. 2 with respect to their respective position in Fig. 1, because of the setting of the folding apparatus 32 arranged in the rotating cutting cylinder 33 together with his

Cutting knife 41 has not changed in this production performed by the printing press. The material web 01 is thus cut - as in the operating situation of FIG. 1 - in each case according to the length a19 for producing the individual sections 19. In contrast to FIG. 1, however, in FIG. 2, the position of the fold line 21 of the transverse fold has been changed by a distance x directed in the transport direction T of the material web 01, which is due to its cause, for example. B. in a desired during production or unintentionally changed setting of preferably in the folder 32nd

provided Querfalzeinrichtung may have. By changing the position of the fold line 21 of the transverse fold, both the distance a09, the width of the web 09, and the distance a12, which defines the width of the web 12, wherein these two webs 09; 12 here each with respect to the relevant section 19 form an Au ßensteg. The web 12 forms in the relevant section 19 a so-called puncture part, because in the region of this web 12 id R. several z. B. along a series arranged point needles of a folding device 32 arranged Punktur- and folding blade 34 attack and pierce the web of material 01 (Fig. 5), whereby 19 so-called punctures are formed on the relevant section. Since the at least one print image 02 associated with print area 03 has remained unchanged in its in the transport direction T of the web 01 extending length a03 in the above-described change in the position of the fold line 21 of the transverse fold, because in the relevant current production of Printing machine z. B. on the setting of the relevant print image 02 printing unit and also on the type 03 has not changed in itself, in the example shown in FIG. 2 compared to Fig. 1 of the web 09 belonging distance a09 has become wider by that measure how the distance a12 belonging to the bridge 12 has become narrower. The web 1 1, which forms a head land in the relevant section 19, as well as the web 13, which forms in the relevant section 19 a foot bridge, remain unaffected by the change in the position of the fold line 21 of the transverse fold.

The change shown in FIG. 2, in particular displacement of the position of the folding line 21 of the transverse fold, preferably results in the folding apparatus 32

printed product to be produced at an overfold or Nachfalz, in which the type area 03 is moved toward towards the relevant section 19 to be attached punctures out, unless countermeasures are taken. Related to an originally z. For example, if the position of the fold line 21 of the transverse fold (FIG. 1) is arranged exactly in a middle of the length a19 of the section 19, which position is preferably set as a desired position, a negative compensation is required in the example shown in FIG 2, the position of the fold line 21 of the transverse fold in the relevant section 19 changed by the distance x to its original position. However, it is also a contrary to the transport direction T of the web 01 directed change in the position of the fold line 21 of the transverse fold by a distance y possible (Fig. 4), this change, in particular displacement of the position of the fold line 21 of the transverse fold then in the preferably in Folder 32 to be produced printed product leads to a lower fold or prefold, in which the type area 03 is moved from being attached to the relevant section 19 punctures away. In this second case is based on an originally z. B. positioned exactly in the middle of the length a19 of the section 19 position of the fold line 21 of the transverse fold (Fig. 1) a positive compensation required to return the distance y changed position of the fold line 21 of the transverse fold to its original position. According to the invention, it is provided that during a displacement of the Position of the fold line 21 of the two transverse to the transport direction T of the web of material 01 directed boundary lines 14; 17 transverse fold to be arranged by the distance x; y in the direction of one of these two boundary lines 14; 17 the relevant position of the at least one between the two boundary lines 14; 17

To be defined set level 03 in particular by a changed setting in the printing image 02 printing unit each in the same direction as the

Displacement of the position of the fold line 21 of the transverse fold is shifted, wherein in the displacement of the position of the fold line 21 of the transverse fold, the relevant position of the at least one set mirror 03 is preferably displaced by an equal amount in the same direction as the displacement of the position of the fold line 21 of the transverse fold , The respective displacement of the position of the fold line 21 of the transverse fold is preferably carried out starting from the setpoint position determined for the fold line 21. When the fold line 21 of the transverse fold assumes its desired position, the respective webs forming an outer web are 09; 12 preferably formed the same width. A changed one

Production setting z. B. in the folder 32 is thus z. B. in the printing unit of the printing machine to the effect that with respect to the respective section 19 of the relevant production to

printing material web 01, the position of the set mirror 03 relative to the position of the relevant section 19 associated fold line 21 of the transverse fold remains unchanged. This fixed relation between the position of the set mirror 03 and the fold line 21 of the transverse fold according to the invention by a corresponding one of

Control unit also be maintained or at least restored when reversed to the previously described example causally a the arrangement of the print image 02 in the respective section 19 relevant setting z. B. changes in the printing unit of the printing press and then a position of the fold line 21 of the transverse fold production adjustment z. B. in the folder 32 is adapted. In the case of an existing or an expected deviation of the position of the fold line 21 of the transverse fold from its desired position, the control or regulation executed by the control unit can therefore be applied to the printing unit the printing press and / or on the press associated with the folder 32 act.

Fig. 3 also shows a printed material web 01 as in Figure 1, but with the difference that within a same between adjacent boundary lines 14; 17 formed portion 19 in the transport direction T of the web 01

next to each other several, z. B. two type mirrors 03 are arranged, each of these typesetting 03 each having a in the transport direction T of the web 01 extending length a03, wherein the respective length a03 of different typesetting levels 03 may also differ from each other. Thus are in the

concerned, provided in the printing machine with at least one print image 02 section 19 of the web 01 at least two typesetting 03 arranged or at least this section 19, wherein at least one first set mirror 03 at a first position in a first region between in the transport direction T of the web 01 first boundary line 17 of the respective section 19 and the position of the fold line 21 of the transverse fold and at least one second masking mirror 03 at a second position in a second region between the position of the fold line 21 of the transverse fold and in the transport direction T of the web 01 second

Limit line 14 of this section 19 are arranged or are. FIG. 4 shows the section 19 of the material web 01 shown in FIG. 3 with a changed position of the fold line 21 indicating the transverse fold, wherein both typesetting elements 03 are displaced away from punctures to be attached to the respective section 19. Between each of the fold line 21 facing edge 24; 26 of the respective typesetting mirror 03 is in each case a web 22; 23, which is in each case referred to as a gutter, wherein between the one of the fold line 21 facing edge 24 is a distance a22 and between the other of the fold line 21 facing edge 26 a distance a23. These distances a22; a23, each having a respective width of the respective webs 22; 23 define, remain unchanged in a change in the position of the transverse fold indicating fold line 21. The relevant position of the at least one between the two transverse to

Transport direction T of the web 01 directed boundary lines 14; 17 set level mirror 03 relative to the position of the between the two

Boundary lines 14; 17 to be arranged transverse fold is z. B. determined that the relevant position of the at least one typeset mirror 03 is determined by an adjustment of a circumferential register on a printing unit of the printing machine at least one print image 02 in the respective type area 03 producing printing cylinder.

The respective circumferential register for determining the respective position of the at least one set mirror 03 and the position of the folding line 21 indicating the respective section 19 are preferably defined by data obtained from a control unit belonging to the printing press, e.g. As a control center of the printing press, in a virtual, preferably electronic lead of this printing press are communicated. An aforementioned negative or positive compensation of a change in the position of the transverse fold indicating folding line 21 is z. B. carried out in that at least a part of the determination of the respective circumferential register and / or the position of the transverse fold indicating folding line 21 required data z. B. be acted upon by the belonging to the printing machine control unit with at least a corresponding increment. This increment changes the respective position of the at least one set mirror 03 as well as the position of the fold line 21 indicating the transverse fold corresponding to the relevant section 19, preferably in a sum of predetermined steps with a minimum step size of z. B. 0.5 mm. For setting longer distances x; y are correspondingly many steps each with the minimum step size required. The maximum adjustment is in the range of z. B. 10 mm to 20 mm, preferably at about 15 mm. By imprinting a corresponding increment on the data communicated in the master axis, the data printed in the printing press with at least one printed image 02 or at least to be printed with type 03 with respect to a cutting position of the material web 01 with respect to their transport direction T either forward or backward, wherein the respective cutting position by the respective position of the transverse to

Transport direction T of the web 01 directed boundary lines 14; 17 is fixed and i. d. R. is not changed. The data defining the circumferential register and / or the position of the transverse fold data z. B. set by the control unit supplied production data.

Fig. 5 illustrates in a schematic representation by way of example, as the relevant position of the at least one directed between the two transversely to the transport direction T of the web 01 boundary lines 14; 17 set set level 03 relative to the position of the fold line 21 of the between the two boundary lines 14; 17 transverse fold z. B. in conjunction with a in the printing press

existing automatic cut register control can be set. In the example shown in FIG. 5, in at least one printing unit of the

Printing machine with at least one print image 02 provided web of material 01 in its transport direction T z. B. via a stationary guide roller 27 and a variable position register roller 28 and a hopper roller 29 a former 31 is fed, by means of which the web 01 is folded longitudinally, after which this web 01 introduced into a folder 32 and other devices of the folder 32 is supplied. In the folder 32 z. B. at least one cutting cylinder 33, a Punktur- and folding blade 34 and a jaw cylinder 36 is arranged, wherein in a Nipp between the cutting cylinder 33 and the Punktur- and folding blade 34, a section 19 after the other from the run into the folder 32 and z. B. already longitudinally folded web of material 01 are separated. This separation method is z. B. executed after each full revolution of the cutting cylinder 33. The separated from the web 01 sections 19 are on the circumference of the Punktur- and folding blade 34 by means arranged there holding elements, in particular

Pointing needles, held and during a rotation of this puncture and Folding blade 34 passed to the jaw cylinder 36, wherein z. B. with the transfer of the relevant section 19 from the Punktur- and folding blade 34 to the jaw cylinder 36 Querfalzung of the relevant section 19 is executed. From the jaw cylinder 36 from the individual reach now at least once also cross-folded portions 19 z. B. via a tape guide to a delivery of the folder 32, where they z. B. are tapped as finished printed products or at least can be tapped.

Establishing the respective cutting position, which the respective position of the transverse to the transport direction T of the web 01 directed boundary lines 14; 17

match, z. B. an automatic cut register control is used, which at least one positionally fixed in the transport direction T of the web 01, on the

Material web 01 directed detection device 37, wherein the z. B. formed as a camera or a scanner detection device 37 is arranged in particular in the region between the registration roller 28 and the funnel inlet roller 29 and at least one on the surface of the web 01 z. B. registered in a printed image 02 register mark and a signal corresponding to this detection of a z. B. electronic control unit 38, wherein this control unit 38 executes at least the cut-off register control in this example. This control unit 38 then controls, depending on the detection of the at least one register mark, the execution of the cutting process 33 to be performed by the cutting cylinder. For this purpose, this control unit 38 outputs a signal z. B. to the effective virtual printing axis in the printing press, which is indicated in Fig. 5 by an output 39 to the control unit 38, from which leading axis and a drive for the rotation of the

Cutting cylinder 33 and a drive for the rotation of Punktur- and

Folding blade 34 and a drive of the relevant at least one print image 02 in the respective type area 03 producing printing cylinder of a printing unit of the printing press are controlled. Since the distance between the position of the registration of the registration mark and the cutting position of the cutting cylinder 33 a is constant from the machine design known machine size, can be with knowledge of a current transport speed of the web 01 and a time for a registered register mark z. B. by means of the control unit 38 readily calculates at what time the separation process is carried out by the cutting cylinder 33. The cutting cylinder 33 is then adjusted by a provided by the virtual lead axis, acting on the relevant drive signal in its rotation angle and thus in its circumferential register such that it executes exactly at the calculated time at the correct position for the supplied material web 01 the separation process. In this way, in this example, the respective cutting position is determined in particular in relation to the respective position of the at least one set level mirror 03 arranged in the respective section 19 or at least one printed image 02 contained therein.

To control the cutting cylinder 33 is an angular position z. B. from the

Rotation axis z. B. detected by means of a preferably optoelectronic encoder, said encoder provides in particular digital data. The respective angular position of the cutting cylinder 33 is always at a certain, predetermined

Reference position referenced. With reference to this reference position becomes the one

Angle position of the cutting cylinder 33 is fixed, in which the cutting blade 41 of this cutting cylinder 33 is preferably directed orthogonal to the perimeter of the Punktur- and folding blade 34 and able to carry out the separation process. It is envisaged that z. B. after each full revolution of the cutting cylinder 33 exactly generates a reference position indicating its reference position and to a the

Cutting cylinder 33 associated control device 42 is passed, this

Control device 42 z. B. with the control unit 38 of the cut register control and / or with a control unit for an actuator of the in Fig. 5 indicated by a double arrow position variable register roller 28 is in a data connection. The control device 42 also has an input 43, to which a control unit 42 is supplied with a signal or at least can be fed, which Signal indicates a current actual position for the transverse fold indicating fold line 21. This the current actual position of the fold line 21 indicating signal is z. B. from a an angular position of the Punktur- and folding blade 34 or the

Falzklappenzylinders 36 detecting rotary encoder generates and / or there on the

tapped encoder.

Although the automatic cut register control can ensure that the at least one arranged in the relevant section 19 type set 03 as centrally as possible between the two transverse to the transport direction T of the web 01 boundary lines 14; 17 is arranged, because the respective cutting position at which the cutting cylinder 33 in cooperation with the Punktur- and folding blade 34 performs the separation process, due to at least one registered register mark is adaptable. However, such a cut-off register control has no possibility of automatically reacting to a change in the position of a fold line 21 belonging to the relevant section 19 and indicating a transverse fold. Therefore, it is provided that the relevant position of the at least one set mirror 03 is determined in relation to the position of the fold line 21 by an adjustment of a circumferential register, said circumferential register z. B. to a certain

Angular position of the relevant at least one print image 02 in the respective type area 03 producing printing cylinder of a printing unit of

Press or to a certain angular position of the cutting cylinder 33 or a certain angular position of the Punktur- and folding blade 34 relates. The drives driving these cylinders in rotation are each connected to the virtual leading axis of the printing press and are controlled or regulated by data or signals communicated on this leading axis.

To the relevant position of the at least one between the two

Boundary lines 14; 17 to be defined set level 03 relative to the position of the between these two boundary lines 14; 17 transverse fold to be arranged is determined, for. B. the reference position of the cutting cylinder 33 indicating reference pulse manipulated by an original value of this reference pulse is applied with a corresponding increment and then the increment of the changed reference pulse instead of the original reference pulse z. B. to the control unit 38 of the cut register control and / or to the control unit for the actuator of the position variable register roller 28 and / or to the control unit for the

at least one print image 02 in the respective type area 03 producing printing cylinder of the printing unit of the printing press is passed. That the

The original value of the reference pulse added increment changes the

Reference position of the cutting cylinder 33 such that this reference position is assigned to a different than the original angular position of the cutting cylinder 33. The supply of the modified reference pulse z. B. to the control unit 38 of

Cut register control and / or to the control unit for the actuator of

position variable register roller 28 and / or to the control unit for the

At least one print image 02 in the respective type area 03 producing printing cylinder of the printing unit of the printing press has the consequence that these control units in the respective control or control carried out by them incorporate the modified reference pulse, whereby the respective control or

Control takes into account the changed position of the fold line 21 of the transverse fold.

The increment added to the original value of the reference pulse is preferably signed to perform positive or negative compensation as needed. In the example described above, the reference pulse indicative of the reference position of the cutting cylinder 33 forms at least part of the data required for setting the respective circumferential register and / or the position of the fold line 21 indicating the transverse fold. The increment represents a rotation angle by which the reference position of the cutting cylinder 33 is changed from an original position for this reference position along a circumferential line of this cutting cylinder 33, so that the reference position of the cutting cylinder 33 is assigned to a different than the original angular position. A full one

Rotation of the cutting cylinder 33 is in several, z. B. divided into one thousand, two thousand or more angle sections, wherein the original position of the

Reference to be added increment represents a rotation angle, which preferably comprises a plurality of vorgenanten angle sections. If the increment is not automatically added to the original value of the reference pulse, then

be provided or that the increment at a belonging to the printing press control station, in particular at one displayed on a monitor

Screen mask, entered and / or changed. A value for the increment is z. B. depending on z. B. of the respective production, d. H. The production data on which this production is based is automatically proposed or at least selectable from a list of values.

This results in a summary of a method for determining a respective position of at least one print area 03 on a in a printing machine with at least one print image 02 to be printed web 01, wherein the at least one print image 02 on one of the respective type 03 mirror useful area of the web 01 is printed, wherein the relevant position of the at least one set mirror 03 is set in a portion 19 of this material web 01, said portion 19 of two in the transport direction T of

Material web 01 at a distance successive, transverse to the transport direction T of the web 01 directed boundary lines 14; 17 is limited, wherein the relevant section 19 at one between its two boundary lines 14; 17 fixed position of a fold line 21 with a parallel to these boundary lines 14; 17 extending transverse fold is provided, wherein in the transport direction T of

Material web 01 consecutively several such each provided with a transverse fold portions 19 are provided, wherein in several of these sections 19, the relevant position of the at least one between the respective two

Boundary lines 14; 17 set level 03 to be defined by one of a Control unit is established at least one of a plurality of successive sections 19 with a data supplied to the control unit 37 detecting an existing or expected deviation of the position of the folding line 21 of the transverse fold of a

Target position is detected, wherein the executed by the control unit or control, in particular a circumferential register of acting on the web 01 or sections 19 cylinder counteracts this detected deviation such that at that portion 19, where the deviation was detected, and / or at at least one section 19 following this section 19 a respective existing before this deviation relative position of the set in the relevant section 19 set level 03 to the desired position of the fold line 21 of

Querfalzes taking into account a valid for this relative position

Tolerance range is restored.
