The invention is based on the object, a device for processing and / or To promote a railway.

This object is achieved by the features of claim 1.

An essential advantage achievable with the device or the method lies in this on the one hand that a lengthy adjustment at the beginning of production is eliminated. in the Contrary to attitudes, which only during the pressure admission means Control loop occurs, the amount of waste is significantly reduced.

A particular advantage of the invention is that it allows rapid adaptation to a Changing the web widths to be processed, as a user does not open each to be moved in adaptation to the web width Web editing tool must access individually.

Another time saving results when the control unit itself is set up necessarily correlated positions of the different Automatic editing tools from a small number of input parameters calculate and adjust. In the simplest case, it is sufficient to calculate this Positions to specify only the width of a web to be processed; the Control unit can from this specification the required positions of all Determine editing tools in a simple way on condition that a Reference line of all webs to be processed, z. B. a right or left margin or preferably the center line, regardless of their width in the device the same Takes position.

Because the required to adapt to a changed web width shifts some web editing tools are firmly correlated, the device can be Simplify by using an actuator to move multiple Web processing tools is used simultaneously.

Belongs to the web processing tools of the device according to the invention for example, at least one former. With a suitable choice of the reference line it can are sufficient if only one of two formers is displaceable; However, you choose what is preferred, the center line of the web to be processed as a reference line, so must at least both of two juxtaposed folders to be displaced.

To from a single output track in the inventive device several To produce partial webs, which are then fed to each individual formers can, the device according to the invention expediently at least one Knife for longitudinal cutting of the original web in partial webs. If more than one such knife is present, at least one of them must be displaceable.

The device may further comprise at least one interval cutting knife for page-wise Having slitting the web. If the material web is a printed paper web, in particular a newspaper, may be such Intermittent cutting knives are used to lift the web locally at the height of each second side to cut so z. B. a broadsheet signature with tabloid insert too to produce.

It is also advantageous if the device has a longitudinal cutting device has at least one knife, which also transverse to the direction of the web is preset to set the cutting line for the partial webs to be produced.

If in the device a cut into several partial webs original web is processed, so are train or Fangrollen as web processing tools expediently assigned to each of the sub-webs in the same way. It is therefore desirable that such roles also according to the width of the processing output track and the number of sub-tracks automatically by the Control unit can be positioned.

Turning bars can also be displaced by the control unit Processing tools are provided. As editing tools are here and in the following also Bahnleit-, Bahnantriebs- and / or web guide elements, such as z. As turner bars, pressure rollers and / or guide rollers understood.

To drive the displacement of the processing tools, the actuators preferably in each case a threaded spindle, and the displaceable Machining tool each have a sliding block, with such a Threaded spindle is engaged.

Advantageously, such a threaded spindle can have a plurality of sections which differ in sense of rotation and / or pitch, and the sliding blocks of several Machining tools of the same type are each in engagement with the various Sections of a same spindle coupled to the editing tools, but if necessary to move in different directions and / or speeds.

Fig. 1a shows a former arrangement, in the two paper webs 01, 02 next to each other via a roller 03 and then in two formers 06, 07 are performed. The formers 06, 07 are in a frame 04 parallel to the axis of the roller 03rd slidably mounted. An actuator for moving the former 06, 07 is formed by a parallel to the axis of the roller 03 threaded spindle 08, the two sections with having opposite slope, and a drive 11, z. B. electric motor 11, for rotational driving the threaded spindle 08. The drive 11 and the former 06; 07 moving gear can also be carried out in other ways. The formers 06, 07 are each provided with a sliding block 09, wherein the two sliding blocks 09 with different sections of the threaded spindle 08 are engaged, so that a rotation the threaded spindle 08, the former 06, 07 drives to opposite movements. An electronic control unit 10 or a system S mentioned below Presetting controls the electric motor 11 based on a user at the Control unit 10 entered (or the system S present) width of the Paper webs 01, 02. The information about the width of the control device 10 (resp. System S) in other ways, for. B. by reading a common value or one in a product planning system, a machine control, a Imposition scheme and / or a control station (denoted by P in FIG. 9) stored value.

A connected to the left former 06 frame 15 or frame 15 is used at the same time as a support for a bearing of the roller 03, so that the roller 03 every movement the Former 06 follows. The right side of the roller 03 is on a frame 04 fixed pin telescopic, z. B. via an axially displaceable bearing 25 (Fig. 1 b), displaceable. With the folding hopper 06, thus displacing the roller 03 and z. B. one on the roller 03 circumferential groove 20 (dashed line in Figure 1 b), which with a Knife for continuous or discontinuous longitudinal cutting as a cutting groove works together.

Also rigid with the former 06, z. B. on the frame 15, is connected Intervallschneidmesser 05 or Skip Slitter 05, which is mounted above the roller 03. The Intervallschneidmesser 05 has a rotating interrupted blade, with the Folding line of the former 06 aligned and alternately on the paper web 01 printed pairs of printed pages each alternately intersects a pair and that others left uncut. When the uncut side pairs are around Broadsheet pages with transverse to the conveying direction lines and the sliced around tabloid sides whose rows are oriented in the conveying direction, so can be from the paper web 01 in a connected, not shown Folder in a simple way a signature with a deposit in half the page size produce.

In Fig. 1 b is the setting of the former 06, 07 for the processing of two Paper webs 12, 13 shown opposite to the paper webs 01, 02 of FIG. 1 a are narrower by a value d. The center line M, at which the tracks 12, 13 touch, has the same position with respect to the frame as the center line M between the Webs 01, 02 in Fig. 1a. To adjust the former 06, 07 for processing such narrow paper webs 12, 13 is via the electric motor 11, the threaded spindle 08 rotated, so that the former 06, 07 each shifted by d / 2 to the center line M out become.

In an advantageous modification or development is with the former 06; 07 - in addition to or instead of the connection to the knife 05 - one of the funnel tip downstream driven roller 30 together or simultaneously with the Forming hopper 06; 07 laterally movable. For this purpose, the former 06; 07 preferably over a common frame 15 connected to a bearing of the roller 30. at Moving the former 6, 07, the roller 30 is moved simultaneously. The roller 30 is designed either as a driven transfer roller 30, via which a the former 06; 07 leaving strand is guided and undergoes a change in direction. In others Execution, the roller 30 as z. B. single motor driven tension roller 30 a Zugwalzengruppe be executed, against which a pressure roller 35 is adjustable. In In this case, the entire train group 30, 35 with the former 06; 07 connected.

Of course, could be a former arrangement of the type shown in Fig. 1a, 1 b also three or more formers for processing a corresponding number of Partial webs have. If three parallel partial webs are to be processed and their Center line M regardless of the width of the webs always the same position in terms of the frame has, so are the two outer formers when changing the width of the To move sub-webs by d each by d, while the middle former remains unshaken. In the case of four partial webs, the displacement d / 2 is correspondingly for the two middle and 3d / 2 for the two outer, etc.

In an advantageous embodiment, it is for presetting the printing press (see FIG. 9). provided that the controller 10 and the drive 11 for the described movement the former funnel 06; 07 is in signal communication with the system S. Based on Production data (eg the web or partial web width b; b ') is the current position of the Forming former 06; 07 with a predetermined or predefinable for this production situation compared and, if necessary, a corresponding movement via setting commands to the relevant Drive 11 causes. Depending on the web or sub-web width and / or location whose center is the former 06; 07 (or the funnel tip) to be positioned laterally. Of the Forming hopper 06; 07 is z. B. Positioned such that the partial web 02; 05 in the center of the Funnel tip on the relevant former 06; 07 runs up. Preset values can be tabulated for the various productions, or it can be found in the System a calculation based on the by the web widths and the lateral offset resulting railways instead.

Fig. 2a shows a catching roller arrangement as a further example of Web processing tools of a device according to the invention. These Fang roller assembly consists of a roller 14, which in operation of a catching, is wrapped in the figure, not shown paper web, a plurality of rollers 16, a plurality of sliding blocks 18, 19, 21, a guide rail 17, a threaded spindle 22nd and one of the already mentioned control unit 10 (or system S) controlled Electric motor 23.

The roller 14 is rotatably mounted in the frame 04. Parallel to the roller 14 is the Guide rail 17 mounted in the frame 04. On the guide rail 17 are several Sliders 18, 19 arranged displaceably. A central to the roller 14 arranged Slider 21 is fixedly arranged on the guide rail 17. The sliding blocks 18, 19 and 21 each carry a rotatably mounted roller 16. The rollers 16 press against the Roller 14 and roll against this. Since the rollers 16 only rotate in one direction are designed to prevent them from running back around the roller 14 Paper web in case of a paper web break.

The threaded spindle 22 pierces the frame 04 on one side and protrudes at this point out of frame 04 It is parallel to the roller 14 and the guide rail 17 aligned. The threaded spindle 22 has two different Thread sections with different directions of rotation, which by a threadless Section are separated. On this threadless section is the sliding block 21 arranged. The two threaded sections have slopes that run along one Longitudinal axis of the threaded spindle 22 proportional to the distance from the sliding block 21st increase. The sliding blocks 18, 19 are left with the seen from the sliding block 21 from or right threaded section not about an internal thread with several Windings engaged - such would be due to the variability of the slope stuck stay, but over a single narrow pin, which on a small Peripheral portion of the threaded spindle 22 engages in the thread on the off the frame 04 protruding end portion of the threaded spindle 22 engages the Electric motor 23 to the threaded spindle 22 at.

If the catching roller arrangement shown for a narrower width paper web is to be used, the sliding blocks 18, 19 along the guide rail 17th shifted, as shown in Fig. 2b. In this case, the threaded spindle 22 via the drive 23rd turned. Due to the different sense of rotation of the two with the sliding blocks 18 and 19 engaged threaded portions move at a rotation of the Threaded spindle 22, the sliding blocks 18 from the left and the sliding blocks 19 from the right on the central sliding block 21 too. The movement of the sliding blocks 18, 19 takes place synchronously, however, as a result of changing along the longitudinal axis of the threaded spindle 22 Slopes of the threaded portions are the paths that the sliding blocks 18, 19 and thus the rollers they drive are 16, proportional to their distance from middle sliding block 21. Depending on the width of the paper web to be processed, the Sliders 18, 19 via a corresponding rotation of the threaded spindle 22 more or less close to the sliding block 21 steplessly move, and the Fangrolle so that set any paper web widths. The sliding blocks 18, 19 can before a Displacement can be arbitrarily placed on the spindle 22; the ratio of their distances remains with a shift.

It would also be conceivable to have two threaded sections, each over their length to provide a constant slope. This is sufficient for a roller assembly with no more than three sliding wheels 16. In the case of a larger number of rollers, as in As shown in Fig. 2b, the distance between the two left sliding blocks 18 (and also between the right sliding blocks 19) remain constant during a shift and Distance ratios would change with a shift.

Another possibility would be for each of the four sliding blocks 18, 19 one own threaded section with specific pitch provided. The variability of Web widths to which the Fangrollenanordnung is adjustable, but then by Restricted that the sliding blocks - at least those with an internal thread several turns are coupled to the spindle - the threaded sections with the for their thread can not leave appropriate pitch,

It could also be several threaded spindles, each with two sections of opposite be provided with the same pitch, the respective sliding blocks of each other with respect to the Bear center line M mirrored opposite roles. These threaded spindles are expediently identical to each other. To different shifts To reach the coupled to them rollers, the threaded spindles of a common electric motor via a gearbox with each adapted Gear ratio driven, or each threaded spindle has its own Electric motor provided by the control unit individually according to the required Shift is controlled.

In the manner just described can also Zugrollenanordnungen for processing paper webs with different widths adjustable execute there Zugrolleanordnungen principle a similar to Fangrollenanordnungen structure exhibit. Such default values can be tabulated for the various Productions are stored, or it is in the system S under a calculation Use of the web widths and the lateral offset to be obtained.

FIG. 3a shows a longitudinal cutting device 71 of a superstructure 67 (FIG. 9). The Longitudinal cutting device 71 is adapted to an incoming web in a plurality Partial webs, e.g. cut longitudinally two partial webs. There are two Guide rails 24 arranged in parallel in the frame 04. A paper web 26 is passed between the two guide rails 24. Two carriages 27 are on the two guide rails 24 slidably held. They are mirror images of each other executed and mounted. Each carriage 27 carries a rotating knife 28 with vertical to the paper web 26 aligned cutting edge and one with the knife 28th cooperating counter-pressure roller 29 (counter knife). Between the carriages 27 there is another knife 32, which is also perpendicular to the paper web 26th stands, and a cooperating with this counter-pressure roller 31. The paper web 26th is the knives 28, 32 and counter-pressure rollers 29, 31 in four sub-webs cut. A parallel to the guide rails 24 threaded spindle 33 has two Thread sections with different directions of rotation and the same pitch, of which each engaged with one of the carriages 27. An end portion of the threaded spindle 33 protrudes from the frame 04 on one side. At this end portion is a drive 34, z. B. electric motor 34, for rotational driving of the threaded spindle 33 is provided. The single knife 28; 32 or counter knife can also be together by a different type of drive 34 or by individual drives per knife or knife pair be drivable.

If the longitudinal cutting device described a paper web 36 with a narrow width Cut into four sub-webs, as shown in Fig. 3b, the threaded spindle 33rd rotated by the electric motor 34. Since the carriage 27 on different Threaded portions of the threaded spindle 33 with different rotation and the same Slope engaged, causes the rotation of the threaded spindle 33 that the Carriage 27 to each other equal distances to each other or to the central blade 32 to move. The rotation of the threaded spindle 33 is continued until the Distance between two knives 28, 32 one quarter of the width of the narrow paper web 36 corresponds.

The operation of the motor 34 is controlled by the control unit 10 (or system S) (Figure 1a). controlled or predetermined, the positions of the knife 28 based on a user widths set or automatically detected by sensors (not shown) cutting web or the partial webs resulting from the cutting.

In the case of several knife units (pairs of knives 28, 32 and counter knife 29) may e.g. all individually driven and / or individually on / off.

The axial positioning or at least presetting of the machine control is preferably automatically based on the intended for printing width of Track and the product-specific cut lines or from a control panel made manually. This is done, for example, before the production start of the system S (from the machine control or a corresponding software program) the current setting to the preset values required for the planned production checked and / or a default by acting on the drive 34 (or the Drives 34). Such default values can be tabulated for the be deposited in different productions, or it can be found in the system S one Calculation using the through the web widths and the to be obtained lateral offset instead.
