Description

The The invention relates to a device for processing a running Material web comprising a feed device for feeding the material web, a discharge device for discharging the web and a web turning station for turning the web on their way from the feeder to the discharge device, and a corresponding method for processing a material web.

devices of this kind are particularly in the field of papermaking or Processing is known to a running web of material or at least a processing station to transport. Should be in one first processing station on a first surface side of the web a coating applied or any other treatment be performed and should be in another processing station on the other surface side the web applied an order or other treatment to be applied, so often exists the need, the material web between the first and the second Turning processing station so that the surface to be treated the Material web in both processing stations same orientation having.

is as a processing station z. B. provided a curtain commissioned work, so in this processing station the web is in one to feed it horizontally that the surface side to be coated the material web faces upward, leaving a coating medium curtain under the influence of gravity down on the moving material web can fall. Should both sides of the material web by means of a Curtain commissioned to be coated, so the material web accordingly between the order stations in a web turning station be turned. Known railway turning stations have two intersecting Turning rods and a deflection bar, so that the material web around the first turning bar, then around the turning bar and subsequently led around the second turning bar and after such three times redirecting finally around 180 ° turns Railway turning station leaves.

Around in known devices for processing a moving web a retraction of the material web, for example after a web break or upon a restart of the device, to facilitate come Feeding arrangements with an endlessly circulating draw-in rope for Commitment. A leading end portion of the web is by means of a so-called kite rope coupled to the feeder rope, so that by movement of the pull-in rope, the end portion of the material web is drawn along the path of the material web.

The Feed rope is substantially straight through the device guided, from one processing station to the next, and so on. At each processing station or at deflection points of the material web, to which the path of the material web it differs from a simple, straightforward way, it is in known Devices required, the end portion of the web or to decouple the kite from the rope, by hand or by means of manually operated tools through the processing station or to thread the special paths of the material web and subsequently again to be coupled to the feeder rope. Especially in the field of known web turning station must conventionally the end of the Material web manually around the crossed turning bars and around the turning bar entrained and the turned material web must after leaving the Bahnwendestation be reconnected to the pull-in rope. This process is laborious and time consuming and limits the effectiveness of the device.

At the Handling with the material web end or with the kite rope during the threading in the turning station exists as well considerable risk of injury to the involved operators. Due to technical reasons this coupling and uncoupling and threading must be performed while the Einzugsseil is already driven, for example, a standing the Einzugsseils in a drying device and thus overheating to prevent the Einzugsseils. The operators are accordingly When pulling in the material web high stress and some danger exposed.

In front It is an object of the present invention to provide a Device for processing a running material web as well to provide a method of processing a moving web of material, with which an end portion of a web faster, easier and with significantly less risk for the operators involved in the device can be retracted.

These The object is achieved by a Device for processing a moving material web of the beginning solved kind, in which a retraction arrangement for retracting a leading End portion of the web along the path of the web is provided, wherein the collection arrangement at least one with a End section of the material web can be coupled, endlessly circulating pull-in rope and a rope guide assembly guiding the at least one pull-in rope having, wherein the cable guide assembly at least one of the turning device associated Seilumlenkabschnitt includes.

Accordingly, according to the invention the at least one pull-in rope is not rectilinear at the web turning station passed by, but with his rope guide arrangement with at least one of the turning device associated Seilumlenkabschnitt so guided, that one coupled to the at least one pull-in rope leading End section of the material web on the pull-in rope through the web turning station threaded is and thus the web on the path of the web is pulled through the web turning station. Accordingly is It no longer required the end section of the web before To decouple the web turning station from the feeder rope, the material web manually thread into the web turning station and then again to couple with the feeder rope. The dangers mentioned in the introductory part and difficulties for the affected operators are thus avoided or significantly reduced. Furthermore, the process of drawing the web after a Web break or a restart of the device much faster and thus be carried out more economically.

In the practical implementation, it will be mostly beneficial if the at least one turning device about which the material web respectively is driven at the feed speed and thus one Transport of the material web supported. So that will be at least a turning device preferably designed as a rotating roller, which is driven with the feed speed of the paper web. If several turning devices are present, then preferably several the turning devices, in particular all turning devices for a driven active transport of the web. By the drive the turning device can be too strong tensile stress of the material web through the pull-in rope and thus a tearing of the material web when pulling through the force of the pull-rope are prevented. Are advantageous for one uniform and secure web feed the drives of at least one turning device and the at least one feeder rope matched.

At This point should be noted that under a rope, in particular a pull-in rope or a coupling rope / band or kite rope, For the purpose of this application, any flexible, elongated connecting element to understand that for the transfer of tensile forces is suitable, in particular also a band, a chain, a thread, a hose or the like. In particular, in an advantageous embodiment the invention thought that several, z. B. two or three, Feeder cables are used, which run side by side. These embodiment is particularly advantageous when for coupling between the web and the multiple pull-in ropes a coupling tape or coupling rope used by a so-called "rope scissors" to the Retractable ropes is held. The coupling tape or coupling cable does not have to be knotted to the feeder rope, so that the Connection between material web and the several feed ropes can be made easier and faster.

In a preferred embodiment the web turning station has two intersecting turning devices and a deflecting device to the material web about a first the turning devices, then to the deflection and subsequently to guide the second of the turning devices. Such, in itself known material web guide has the advantage that the direction and orientation of the supplied and dissipated Material web relatively freely selectable are, in particular such that supplied and discharged material webs in Essentially parallel to each other and running in the same direction. According to the invention the intake assembly of this embodiment a cable guide arrangement with at least one of the first turning device associated Seilumlenkabschnitt, one of the second turning device associated Seilumlenkabschnitt and one of the deflection associated Seilumlenkabschnitt on. In this way, the pull-in rope is assigned to the deflection points the web so led in the web turning station that one with the feeder rope coupled end portion of the web on the pull-in rope in the web turning station automatically threads. The most difficult and for the affected operators also dangerous manual retraction the material web between the crossed turning devices and Thus, the diverter can safely, quickly and reliably automatically carried out become.

Preferably is the end portion of the web by means of a coupling rope / bands can be coupled to the draw-in rope. Here comes especially a kite band or kite rope with the tip of a triangular kite is connected, with an opposite Long side of the Kite with a leading, running across the web Edge of the end portion of the web is connected. Through a such kite rope in conjunction with a kite can be a traction in a conventional manner evenly over the entire width of Material web are introduced into the web.

The entry of the material web into the web turning station with the help of the feeder rope is difficult because of such a coupling rope / bands, especially kite rope, since the coupling rope / band is stretched from the feeder rope to the axial center line of the web and thus extends at an angle to the feeder rope, so that at the turnstile len both the pull-in rope and the coupling cable / band running away from it and tape and the material web connected thereto must be deflected. At the same time, however, the pull-in rope and the material web can not be deflected onto one and the same roller or roller, since the material web must be transported at the latest in normal operation at a much higher speed than the pull-in rope.

Around Nevertheless, an automatic retraction of the end portion of the web also along a complicated path through the Bahnwendestation too enable, is in a further embodiment the invention provides that the cable deflection section has a delivery side, at which he slipping the coupling rope / bands of the Seilumlenkabschnitt in a direction transverse to the direction of the pull-in rope and a Movement of the coupling rope / band in one direction to the axial one Center line of the path of the material web allowed. In operation can thus the pull-rope continuously safely deflected in the Seilumlenkabschnitt while the Coupling rope / band only a small distance at the Seilumlenkabschnitt is diverted and then slides from the Seilumlenkabschnitt to the material web longitudinal center to run.

Around a reliable one Slipping of the coupling rope / bands from the Seilumlenkabschnitten to support, It is proposed that at an operating time on an Seilumlenkabschnitt deflected coupling cable / band of the Seilumlenkabschnitt to the material web end at an angle inclined to a deflection plane the Seilumlenkabschnitts runs. The tendency is to choose that the coupling rope / band to the delivery side of the Seilumlenkabschnitts slides down. Such a tendency is thereby in practice corresponding arrangement and orientation of Seilumlenkabschnitts be realized in relation to the material web. In other words Slipping of the coupling rope / band from the Seilumlenkabschnitt support when the discharge side of the Seilumlenkabschnitts to the material web out points or at least a piece is arranged inclined in the direction of the material web, since the coupling cable / band strives to slide off towards the web center.

alternative or additionally Slipping of the coupling rope / band from the Seilumlenkabschnitt achieved or supported by that the discharge side of the Seilumlenkabschnitts substantially perpendicular or at an angle points down to the ground. The coupling rope / band slips then under the influence of gravity, so to speak of the Seilumlenkabschnitt from. It may also be helpful already, the delivery side of the Seilumlenkabschnitts to orient essentially in a horizontal direction, so that the gravity of slipping the coupling rope / bands at least does not counteract. Slipping of the coupling rope / bands can then be achieved, for example, by the fact that the delivery side the material web faces.

One reliable Slipping of the coupling rope / bands from the Seilumlenkabschnitt can further supported by it be that the Seilumlenkabschnitt, with respect to a through the Deflected rope defined deflection plane, on one side of the deflection plane having a delivery track which causes slippage of the coupling rope / band from the cable turning portion in a direction transverse to the running direction of the feeder rope allows or supported. Such a delivery path can be achieved by a flattening of the cable deflection section, preferably rope gentle without sharp edges, be formed.

alternative or additionally Slippage of the coupling rope / band is toward the delivery side supported thereby, that on the other side of the deflection plane provided a blocking means which is a sliding of the coupling rope / bands of the Seilumlenkabschnitt counteracts in a direction transverse to the direction of the pull-in rope. The blocking agent may in particular prevent during the Operation due to vibrations or due to a temporary Lose the coupling rope / band the coupling rope / band to the "wrong" side slides off the Seilumlenkabschnitt, d. H. not from the delivery side, which would lead to that the coupling rope / band gets caught on the device and the ongoing collection process disturbed becomes.

In a particularly simple and reliable working embodiment is the Seilumlenkabschnitt or at least one of Seilumlenkabschnitte by a pulley with a trough for guiding the feeder rope or formed the coupling rope / bands. The track of the pulley can then between two surrounding walls be defined what different height above the bottom of the trough exhibit. In this way, a auflaufendes on the pulley Coupling rope / band, which initially is guided in the trough, slightly over the lower of the two circumferential walls leave the trough and slide off the pulley. An expiration of the coupling rope / bands over the higher Wall is made more difficult. The lower wall then forms one Abgabekahn or a discharge side, while the higher wall is a blocking agent represents.

In a preferred variant of the embodiment described above, the lower wall of the cable pulley merges into an axis of rotation of the pulley substantially to the concentric-cylindrical discharge surface. The coupling rope / band can then after leaving the trough on the low re wall be supported a distance on the centric-cylindrical discharge surface before it completely slides off the pulley.

Around a slipping or jumping out of the coupling rope / bands on the the delivery side opposite side of the pulley effectively prevent the pulley on the side of the higher wall a rollover protection disk wear. This rollover protection disk has an even larger radius on as the higher one Wall, and can thus even at temporary occurrence of a lot in the coupling rope / band a jumping off of the coupling rope / bands from the pulley in the opposite direction to the discharge side prevent. The rollover protection disk can be provided as a separate disc or in one piece with the higher wall be educated. Alternatively, the rollover protection can also even the higher one Form wall, leaving the trough of the pulley between the rollover protection disc and the lower circumferential wall is defined. For a particularly reliable effect has the rollover protection disk a diameter that is at least twice as large as we the diameter of the track of the pulley.

A Pulley acting as Seilumlenkabschnitt the invention is preferably on the part of the higher Wall, d. H. flying on the opposite side of the delivery side, d. H. only one-sided, stored. Accordingly, the rotation axis the pulley connected only on one side with the device while the Release side of the pulley remains free and thus slipping the Coupling rope / bands without the risk of obstruction with bearing or fasteners allowed.

Basically it is possible the device according to the invention to realize so that the pull rope pretty much the way the material web follows through the web turning station, so that the material web end on the pull-in rope in the path of the material web is withdrawn. However, the inventors are at a surprising Effect encountered, the occurs when the cable guide assembly the pull-in rope leads in such a way, that the pull-in rope and the material web at an inlet point of Bahnwendestation and at an outlet point of the Bahnwendestation each parallel to each other, but the cable guide on the web turning station is designed such that a path of the material web is shorter by the web turning station from the inlet point to the outlet point as a path of the pull-in rope from the inlet point to the outlet point. It has been observed that with such a special cable guide during the Drawing in the material web a tensile force drop in the tension of the coupling rope / bands, d. H. a temporary loose in the coupling rope / band, occurs, and that by this loss of traction or these lots slipping of the coupling rope / bands caused by the Seilumlenkabschnitt or supported.

Of the Drop in traction hangs together with that before and after the Bahnwendestation the Feed rope and the material web coupled thereto at the same speed move parallel to each other (the pull-in rope pulls the material web). On the one hand leads then the running path difference according to the invention between draw-in rope and material web within the web turning station that for a long time Path guided Retractable rope - up related to the path of the material web - slower than the material web, so that the tensile force in the coupling rope / band, which the pull-in rope connects to the material web, temporarily decreases.

Especially that is true loose coupling rope / band almost independently from a Seilumlenkabschnitt when the discharge side of the Seilumlenkabschnitts inclined downward is. But also on horizontal or even upwardly directed Seilumlenkabschnitten leads one Lose occurring to the fact that the guided on the pull rope coupling rope / tape beats and of the Seilumlenkabschnitt abspringt.

Of the The difference in travel between the material web and the pull-in rope should be but not too big, so that the traction force does not lead to a too high voltage peak when catching up the lots, z. B. by brief acceleration of the feeder rope, leads, which could otherwise result in a web break.

In a further preferred embodiment, it is provided that the infeed rope adjoins and parallel to a longitudinal edge of the web path at an entry point of the web transfer station, that the infeed rope in the passage between entry point and exit point crosses the center line of the path of travel of the material web and that the infeed rope a / the outlet point of the web turning station of the other longitudinal edge of the web adjacent and parallel to this. Accordingly, in this embodiment, the pull-in rope to run at the inlet point next to one of the longitudinal edges, while it runs at the outlet point next to the other longitudinal edge of the web. However, since the material web is turned between inlet point and outlet point in the web turning station, this embodiment achieves the effect that the pull-in rope runs before and after passing the web turning station on the same side of the axis of the web path. This has considerable structural advantages result, since the cable guide of the pull-in rope can be arranged in sections before and after the web turning station on the same side of the longitudinal axis of the web path and also a renewed side change of endless Einzugsseils before re-reaching the entry point is not necessary. Furthermore, the pull-in rope is accessible to operators for the purpose of coupling and uncoupling the coupling rope / band from the same side of the device. These effects are particularly effective when the cable guide assembly leads the pull-in rope such that a path of the pull-in rope at the inlet point of the web turning station and a path of the pull-in rope at the outlet point of the web turning station substantially lie on a common line.

The embodiment described above, in which the draw-in rope crosses the center line of the path of travel of the material web, However, at the same time achieves the further effect that the path of the Einzugsseils from the inlet point to the outlet point is longer than the corresponding Path of the material web, as the pull rope not only along the Material web path from the inlet point to the outlet point runs, but about that also traverse the web from one longitudinal edge to the opposite longitudinal edge got to. However, this will happen simultaneously and without additional constructive effort of the effect described in more detail above a temporary reduction in traction in the coupling rope / band, allowing the coupling rope / bands to slide off the pulleys supports becomes.

A structurally simple realization to achieve a path difference between web and rope and if necessary to guide the Via rope the centerline of the web can be achieved when the Roping arrangement the pull rope leads in such a way that a path of the pull-in rope at the at least one turning device and / or at the deflection parallel and adjacent to a deflection of this Facility, that is So a piece far at this deflection area along, runs. In particular, it is possible Parts of the cable guide arrangement with parts of the turning device or deflection or fasteners to do this as an assembly.

If Furthermore, at least one Seilumlenkabschnitt the cable guide assembly one on the axis of the at least one turning device and / or the Bearing roller bearing mounted, so can space and constructive Effort can be saved, since the role with the turning or deflecting device executed as an assembly can be. The role may be a known pulley.

The Retractable rope is preferably by a separate drive device driven to move. In particular, this drive device independently from the drive of the feeder, the removal device or the web turning station of the material web provided. Furthermore, can the speed of the feeder rope preferably by a control device to be controlled. In this way, the pull-in rope with a Feeding speed to be moved, which is used to retract the web is suitable while it in the normal operation of the device, for example, clearly reduced speed is constantly being moved. Especially then when the pull-in rope also passes through a drying device is by a continuous, slow movement of the Einzugsseils a Excessive heating of the draw-in rope inside the drying device prevented. In other devices, the movement of the feeder rope be completely stopped in normal operation of the device.

In a further embodiment The invention provides that the control device an acceleration means for temporarily accelerating the movement of the pull-in rope a speed above a normal feed speed includes. By temporary acceleration of the feeder rope can a temporary one Traction force reduction occurring in the coupling rope / band or in the pull-in rope or a lot in the coupling rope / band are compensated again, around the necessary to retract the web traction on the coupling rope / band rebuild. In particular, a loss of traction or a lot due to the sliding action described above in more detail of the coupling rope / bands of the at least one Seilumlenkabschnitt can be compensated by such an accelerator again.

To the temporary acceleration, the feed rope still a certain Time with the increased Speed be moved until the desired tensile force in the coupling rope / band or is restored in the pull-in rope, if the desired Traction not already during of acceleration. After that, the speed of the Retraction rope reduced to the normal retraction speed, for example, using a braking means for braking the Movement or alone by reducing the driving force, so that the speed of the intake rope due to the friction in the cable guide falls back to the normal feed speed.

The device according to the invention operates particularly comfortably when the control device is set up to detect the occurrence of a reduction in the tensile force on the coupling cable or on the draw-in cable and to temporarily accelerate the draw-in cable when the reduction in tensile force occurs. Alternatively or additionally, the Control means are adapted to detect the occurrence of a running path difference or a running speed difference between the pull-in rope and the material web and to temporarily accelerate the pull-in rope after occurrence of the difference. In this way, a fully automatic feed operation can be realized.

When another possibility it is conceivable that the control device, the position of the coupling rope / bands at any time of the drawing process knows and due to the the rope guide fixed path differences between endless rope and material web the speed of the pull-in rope according to a pre-set program dependent controlled by the path difference. An automatic operation is then also possible without continuous measurement of feedback values.

to increase the flexibility or as a particularly simple variant is also conceivable that the accelerating agent manually, for example, over one Push-button switch, can be actuated is.

The Advantages of the device according to the invention come especially to bear, if the device at least one Commissioned work, in particular curtain applicator, for applying a Having coating on the web. So z. B. in the direction of travel the web both before and after the Bahnwendestation respectively arranged at least one commissioned work, especially curtain commissioned work be so that it is possible is to coat both sides of the web through the commissioned work.

in the Area of the web turning station, it may be preferred, the material web contactless support and divert by the at least one turning device and / or the deflection produce an air cushion. Also not one or not yet not yet complete dried web can then without damaging the still wet job turned in the turning station.

In a preferred embodiment for contactless guide the material web is provided that the outer surface of the at least one turning device and / or the deflection device a plurality of air outlet openings and the device comprises a setting means for selectively opening or Shut down has at least one selection of the air outlet openings. The air-emitting air outlet openings the turning device or deflection can then to the position or adapted to the width of the material to be transported web be, by only the covered by the material web air outlet openings open and all other air vents are closed. In this way, the compressed air is used particularly effectively. To the closure not needed Air outlet openings the adjustment means may comprise a cover film, in particular a magnetic film, include, with which optionally at least one selection of the air outlet openings can be covered. Such a cover sheet can be provided inexpensively be and take care of a reliable one Closure of the air outlet openings. A magnetic foil may interact with one made of ferromagnetic Material formed deflection or turning device a Ensure particularly secure hold of the cover foil.

In a further preferred embodiment invention, the device has a bypass track guide, to the web with constant orientation of the feeder to the discharge device respectively, d. H. So without turning, the material web either via the web turning station or over the bypass track guidance is transportable. Depending on the application, then the material web can be with or without turning from the feeder transport to the discharge device.

Around also to facilitate the pulling into the bypass track, is in a further embodiment the invention provided that the collection arrangement set up for it is, the material web either in the web turning station or in the Bypass web guide collect.

To Another aspect of the invention is the above-mentioned task solved by a method of processing a traveling web, comprising the steps: Feeding the web, turning the web by the web is guided by at least one turning device, and discharging the Material web, wherein the process involves a process of retracting a leading End portion of the web along the path of the web comprising the steps of: coupling an end portion the web with an endless circulating feeder rope, wherein the feeder rope is associated with at least one of the turning device Led Seilumlenkabschnitt is, driving the feeder rope to the web around the first Feed turning device around, decoupling the end portion the web of the feed rope.

preferred embodiments This method is given in the accompanying subclaims.

By the method according to the invention, the technical effects and effects he aims, as have been explained above for the corresponding devices according to the invention as well as special embodiments of the devices according to the invention. Reference is expressly made to the corresponding description of the invention.

It should be noted is at this point that the inventive device and the inventive method For particularly simple implementation or cost-effective conversion by a combination of per se known in the art Individual components according to the above instructions according to the invention can be realized. Thus, in particular, the feeding device be known per se Abrollung, the discharge device can on be known reeling, the turning devices can by Known turning bars are provided and as a deflection it is possible to use a web guide roll known per se.

The The present invention will be described below with reference to preferred embodiments with reference to the attached Drawings explained. Show it:

2 a detail of the device according to the invention for illustrating a coupling between a pull-in rope and a material web end,

3 a perspective view of a web turning station according to a first embodiment of the invention,

4 a perspective view of a web turning station according to a second embodiment of the invention,

5 a cross-sectional view of a first embodiment of a pulley of a web turning station according to the invention, and

6 a cross-sectional view of a second embodiment of a pulley of a web turning station according to the invention.

In 1 is with the reference numeral 10 in general, a device for processing a moving paper web 12 designated. The paper web has a first surface side 12a and an opposite second surface side 12b on. Both surface sides 12a . 12b the paper web 12 should in the device 10 coated with application medium.

The paper web 12 is from an unwinding 14 in a horizontal plane continuously fed so that the first surface side 12a pointing substantially vertically upwards and the second surface side 12b pointing substantially vertically downwards. After unrolling the paper web passes through a first curtain commissioned work 16 , which is a first application medium in the form of a free-falling curtain 18 on the first surface side 12a applying. Subsequently, the paper web 12 by a first drying device 20 in which the applied layer is dried.

In the apparatus of the embodiment, not only the surface side is intended 12a , but also the opposite surface side 12b the paper web 12 coated with application medium, in particular by means of a second curtain applicator 22 , So also the second curtain commissioned work 22 with a free-falling application medium curtain the coating on the surface side 12b can make the paper web 12 before entering the second curtain commissioned work 22 in a railway turning station 24 be turned so that when entering the second curtain-commissioned work 22 the not yet coated surface side 12b essentially perpendicular to the top, while passing through the first commissioned work 16 coated surface side 12a pointing down.

After coating the second surface side 12b through the second curtain commissioned work 22 the paper web is in a second drying device 26 dried again. After leaving the second drying device 26 the paper web is on a reel 28 rolled up.

Is a turning of the web before reaching the second curtain applicator 22 not wanted, because about the first and second commissioned work 16 and 22 both the coating on the same surface side 12a or only one of the curtain commissioned works 16 . 22 to perform a coating, so can the web 12 optionally by a bypass track guide 25 be guided, which the Bahnwendestation 24 bypasses and thus transports the paper web without changing the orientation to the second curtain commissioned work.

To a leading end portion of the paper web after a web break or when restarting the device 10 from the unwinding 14 in the path of the device until reeling 28 to retract, the device has 10 an intake arrangement with an endlessly circulating draw-in rope 30 on. The pull rope 30 runs in association with the path of the paper web through the first commissioned work 16 , the first drying device 20 , the railway turning station 24 or the bypass track guide 25 , the second curtain commissioned work 22 and finally through the second drying device 26 and is powered by a drive and tensioning device 32 back to the first curtain commissioned work 16 guided. In a manner to be described in more detail later, the pull-in cable is driven by the drive and tensioning device 32 driven to a revolving motion with variable speed.

2 shows in more detail an example for establishing a coupling between the pull-in rope 30 and the paper web 12 , In a manner known per se, on a straight and substantially perpendicular to the longitudinal center axis M of the paper web 12 extending end edge 12c the paper web 12 a long edge of a kite 34 attached. The Dragon 34 is preferably formed by a sturdy leather triangle. For attachment between kite and end edge 12c the paper web 12 An adhesive tape or other suitable compound can be used.

While one edge of the triangular kite 34 with the end edge 12c the paper web 12 is connected to the opposite tip 36 of the kite, which is approximately on an extension of the longitudinal center axis M of the paper web 12 lies, a kite rope 38 attached, which is formed for example as a textile tape. For a reliable operation of the device has a kite rope with a length which is at least twice as large as the width of the paper web 12 , proved useful.

The kite rope 38 is made by suitable coupling means with the pull-in rope 30 coupled, for example, manually tied by an operator to the feeder rope / knotted. By the in 2 Pictured coupling between pull rope 30 and paper web 12 may be a pulling force exerted by the pull-in rope in the paper web 12 be initiated without the paper web 12 Too much stress and the risk of tearing the paper web would exist.

Alternatively to the in 2 illustrated coupling are other ways of connection between pull-rope 30 and paper web 12 conceivable, for example, by the use of several pull-in ropes next to each other. In this case, the coupling usually takes place no longer by Anknoten the kite rope, but by pinching the kite rope between the Einzugsseilen in a rope scissors instead. A similar reverse arrangement releases the kite rope before reaching the reel. A rope scissors can also be used with more than two pull-in ropes by the dragon belt is clamped between at least two of the pull-in ropes.

According to the invention, the feed arrangement of the device 10 set up the paper web 12 not only by the commissioned works 16 . 22 and the drying facilities 20 . 26 but also in the web turning station 24 threading. To explain this intake arrangement is hereinafter on 3 and 4 Referring to which two variants of the web turning station 24 illustrate with associated intake arrangements. Both 3 and 4 illustrate embodiments in which the material web 12 by means of two crossed turning bars 40 . 42 (Turning devices) and a deflection bar 44 (Deflecting) is turned over a total of three times, so that the paper web 12 , which at the entry point A of the web turning station 24 so enters, that the first surface side 12a facing up and the second surface side 12b points downwards, at the exit point B of the web turning station 24 so expires that the first surface side 12a points down and the second surface side 12b points upwards. Both at inlet point A and at outlet point B, the paper web runs 12 each in a horizontal plane. In 3 and 4 is the first surface side 12a by a dash pattern and the second surface side 12b illustrated by a circular pattern.

It should be noted is that under the inlet point or outlet point in the sense of this Register a position along the path of the web or of the pull-in rope, and not necessarily one geometric point. For example, if it is said that material web and infeed rope at the entry or exit points move the web turning station parallelel to each other, then this should parallelism for one Point of the pull-in rope and a point of the center axis of the material web apply, using both points on a common orthogonal to Parallel direction, d. H. at the same height in the direction of the paper web and the Einzugsseils lie.

To allow the direction of travel of the paper web 12 before and after the Bahnwendestation 24 is equal, the paper web becomes 12 in the Bahnwendestation 24 first at a 45 ° to the direction of the paper web 12 inclined horizontal turning bar 40 Guided, leaving the paper web 12 turned and their direction is changed by about 90 °. Subsequently, the paper web 12 around the turning bar 44 guided so that it is turned again and their direction of rotation is rotated by 180 °. The deflection bar 44 is approximately parallel to the direction of the paper web 12 in the inlet and outlet point A, B (main direction of the paper web 12 ), but laterally offset. Finally, the paper web 12 around the second turning bar 42 guided around, which are crossed by about 90 ° below the first turning bar 40 and thus inclined by about -45 ° to the direction of the paper web 12 runs, so the paper web 12 is turned for the third time and their path is again changed by 90 ° and finally again the direction of the paper web 12 at the entry point A occupies.

If, instead of turning bars or deflecting bars, other turning devices or deflecting devices are used which do not have a substantially elongate shape, the statements made here for the orientation and arrangement of the turning bars or deflection bars relate to the orientation and arrangement of the elongate deflection surfaces of such turning devices or deflection devices at which the material web is deflected. Such a deflection surface is in 3 by way of example with the reference numeral 45 characterized.

The turning bars 40 . 42 as well as the deflection bar 44 are arranged in three different horizontal planes, wherein the planes of the rods have such distances from one another that the from the inlet point A to the first deflecting rod 40 extending paper web section of the first turning bar 40 to the deflection bar 44 extending paper web section of the turning bar 44 to the second turning bar 42 extending paper web section and that of the second turning bar 42 extending to the exit point B paper web section all substantially in horizontal planes.

According to the invention, the pull-in rope 30 also in the area of the web turning station 24 led to the paper web 12 after a web break or when restarting the machine in the web turning station 24 threading. The variants of the 3 and 4 differ in the course of the feeder rope 30 ie in the arrangement of the pull-in rope 30 leading rope guide.

In the first embodiment according to 3 the rope pulls in 30 at the inlet point A initially parallel next to a first longitudinal edge 46 the paper web 12 and is - viewed in the direction of the paper web or the feeder rope - first by a first role 48-1 diverted, then runs next to the first turning bar 40 parallel to the turning bar to the opposite second longitudinal edge 50 the paper web 12 and will be there on a second roll 48-2 redirected again. Thus, the pull rope crosses 30 at the first turning bar 40 the first surface side 12a the paper web 12 that is, it crosses the longitudinal center line M of the paper web 12 Finally, in the further course in the vicinity of the second longitudinal edge 50 through the web turning station 24 to run.

From the second roll 48-2 the rope pulls in 30 parallel to the second longitudinal edge 50 to the deflection bar 44 on which there is a pulley 66 is diverted. The pulley 66 is concentric on the deflection bar 44 stored, sitting in particular on the same rotary shaft, but is independent of the deflection rotatable, so that the pulley 66 and the turning bar 44 can rotate at different speeds.

The pull rope 30 then runs parallel to the second longitudinal edge 50 to the second turning bar 42 and is there by a third and a fourth role 48-3 . 48-4 around the second turning bar 42 guided around to finally parallel to the second longitudinal edge 50 to run out through the outlet point B.

The embodiment according to 4 differs from the variant of the 3 among other things, that the pull-rope 30 about roles 48'-1 . 48'-2 . 48'-3 and 48'-4 until the second turning bar 42 in the neighborhood and parallel to the first longitudinal edge 46 is guided and only at the second turning bar 42 the paper web 12 crossed. In the embodiment of 4 the pull-in rope runs 30 in particular parallel next to the second turning bar 42 from the first longitudinal edge 46 to the second longitudinal edge 50 , where it is the longitudinal center axis M of the paper web 12 crossed. The pulley 66 ' sits in comparison to the embodiment according to 4 according to the other end of the deflection bar 44 ,

In principle, it would also be possible for the pull-in rope 30 the paper web 12 crosses at another point on the way between inlet point A and outlet point B, however, the embodiments are according to 3 and 4 considered particularly advantageous because the leadership of the feeder rope on the one hand in association with one of the turning bars 40 . 42 can take place and at the same time an oblique crossing of the web, for example, at an angle of 45 ° to the longitudinal central axis M, prevents too abrupt or excessive drop in traction in the kite.

Each of the roles 48-1 to 48-4 respectively. 48'-1 to 48'-4 for deflecting the Einzugsseils may preferably according to one of the following two, with reference to 5 and 6 detailed examples of roles 48a and 48b be executed.

The inventors have found that the automated web feed according to the invention in principle also using a known pulley 48a can be realized, as for example in 5 shown in cross section. Such a pulley 48a has a pivot 52 , a roller body rotatably mounted thereon 54a and a pivot 52 on a device fixed section holding holder 57a on. The reel body 54a is with a rotation axis X encircling track 56a formed in which the feed rope 30 expires and is diverted. The trough 56a is between two surrounding walls 58a . 58a defines which are both the same height h above the bottom of the trough 56a exhibit.

In 5 is also the dragon rope with dashed lines 38 indicated, which at a connection point 60 with the pull rope 30 connected is. Depending on the mounting of the roller 48a relative to the path of the paper web 12 that is, depending on the orientation of the rotation axis X with respect to the paper web, the kite rope runs 38 at a certain angle α to the pull-in rope 30 , Will now be the feed rope 30 continue in the direction of an arrow E in 5 The point of connection also reaches this point 60 the gutter 56a and the kite rope 38 begins, in the trough 56a also to thread. Because, however, the kite rope 38 at an angle α to a through the course of the feeder rope 30 on the roll 48a Defined deflection U of the role 48a runs, the kite rope runs 38 not completely in the trough 56a but slides over the boundary wall 58a away from the role 48a from. Thus, the kite rope 38 on the pull-in rope 30 also about the role 48a be pulled away.

A reliable and smooth sliding of the kite rope can by one or more of the features of the invention of the role 48b according to 6 be achieved. The role 48b this variant differs from the role 48a of the 5 first in that it is mounted in a different orientation to the device. In 6 it can be seen that a holder 57b above a reel body 54b is arranged so that a free side of the roll 48b points down to the ground. Already by such an orientation is a slipping of the kite rope 38 from the trough 56b supported downwards through the delivery side by gravity. The effect of the gravity support occurs to a lesser extent, even if the axis of rotation X is not perpendicular, but inclined at an angle to the vertical, provided that the discharge side of the roll points down.

Furthermore, a slipping of the kite rope 38 out of the trough 56b in the example of 6 supported by the fact that the boundary wall 58c on the delivery side of the roll 48b a lower height u above the bottom of the trough 56b has as the height h of the opposite boundary wall 58b on the part of the owner 57b , In particular, the boundary wall 58c flattened and goes into a concentric with the axis of rotation X extending, cylindrical discharge surface 62 over, whose height u above the bottom of the trough 56b also smaller than the height h of the opposite boundary wall 58b , Through the delivery area 62 is also during the descent of the kite rope 38 a defined leadership of the kite rope 38 allows.

As particularly reliable has a height u the flatter wall 57c between about 0 and 20 mm, preferably about 10 mm. Also, a substantially completely flattened wall or a variant in the gutter 56b only on the side opposite the delivery side by a wall 58b is limited and unlimited on the delivery side or directly into a delivery area 62 goes over, has proved to be suitable and thereby particularly easy to manufacture possibility for carrying out the invention.

The role 48b the in 6 shown embodiment also has on the side of the higher boundary wall 58b ie on the part of the holder 57b , a rollover protection disk 64 on, which has a much larger radius than the trough 56b , preferably more than twice the radius. The rollover protection disk 64 prevents even with jerky movement of the feeder rope as well as in the occurrence of a loose in the kite rope 38 a jump off the kite rope 38 to the holder 57b out. A loose or beating kite rope can thus only to the delivery area 62 out of the role 48b slide.

Referring again to 4 and 5 It should be noted that in the web turning station according to the invention 24 . 24 ' each of the roles 48-1 to 48-4 such as 48'-1 to 48'-4 is formed or oriented so that at least one of the features described above, the sliding of the kite rope 38 out of the trough 56 allow or support, preferably several such features, is / are met.

In the embodiment according to 3 are preferably all roles 48-1 to 48-4 in the in 6 shown type with delivery area 62 and rollover protection 64 fitted. Further, the first role 48-1 and the second role 48-2 so oriented that you holder 57 each is disposed at an upper position and its discharge surface 62 pointing downwards. A slipping of the kite rope 38 is thus supported by gravity.

Further, the roles 48-3 and 48-4 arranged horizontally, ie their axes of rotation lie in horizontal planes, wherein the axes of rotation in each case approximately perpendicular to the incoming in the rollers feeder rope 30 run. Besides, the roles are 48-3 or 48-4 so oriented that their delivery pages 62 each to the paper web 12 towards, more precisely to the adjacent second longitudinal edge 50 clues. With In other words, with respect to a deflection plane U, by the deflected on the roller feeder rope 30 is defined, the delivery side 62 arranged on the same side as the adjacent portion of the second longitudinal edge 50 the paper web 12 or an upstream of the roll 48-3 respectively. 48-4 running section of the paper web 12 while the respective holder 57 the role 48-3 respectively. 48-4 is arranged on the other side of the deflection plane. In this way, the kite rope can also run on the rollers 48-3 respectively. 48-4 Slightly slide off the rollers over the delivery sides of these rollers, leaving the kite rope 38 through the roles 48-3 respectively. 48-4 essentially not hindered.

In the embodiment according to 4 are the first role 48'-1 and the second role 48'-2 comparable to the third and fourth roles 48-3 and 48-4 the embodiment according to 3 arranged, ie with a substantially horizontal axis of rotation and with the material web facing discharge side 62 , The third and fourth roles 48'-3 and 48'-4 On the other hand, they are arranged such that their holders 57 are each arranged at a lower position and their delivery sides 62 each directed upward. Both roles 48'-3 and 48'-4 each have a rollover protection 64 on. At these roles 48'-3 and 48'-4 will be a detachment of the kite rope 38 from the running channel of the roles significantly by the path difference between the path of the feeder rope 30 and the path of the paper web 12 caused. Due to a resulting relative speed between the pull-in rope 30 and paper web 12 it comes to a brief beating or jumping the feeder rope, which has been found that by this irregular movement, the pull-in rope 30 from the roles 48'-3 . 48'-4 jumps upwards. This effect may also be due to a rebound of the beating feeder rope 30 from the rollover protectors 64 due.

It should be noted that at an outer end portion of the turning bar 44 respectively 44 ' rotatably mounted pulley 66 respectively. 66 ' also forms a Seilumlenkabschnitt, on which the feed rope 30 is deflected by 180 °. Also the pulley 66 respectively. 66 ' has a raceway for guiding the feeder rope 30 on, wherein a boundary wall of the trough on the side of the paper web 12 such a height above the bottom of the trough that the entering into the trough dragon rope 38 can slide off the trough to move towards the paper web. In particular, again on the side of the paper web, the height of the boundary wall of the trough is lower than on the opposite side of the trough.

The following is a brief operation of the device shown in the figures when drawing a paper web 12 after a web break or at a restart of the device described. In the area of unwinding 14 becomes the paper web 12 over the kite rope 38 on the pull-in rope 30 attached, for example, knotted. That through the drive and tensioning device 32 driven pull rope 30 then pulls the paper web 12 over the kite rope 38 through the device 10 and thread the paper web 12 in their path. In the area of the Bahnwendestation 24 it comes at the described points where the path of the feeder rope 30 from the path of the paper web 12 deviates (especially on the turning bars 40 . 42 ) to a temporary relative movement between the paper web 12 and rope 30 leading to a temporary reduction in traction in the kite rope 38 in other words, a lot in the kite rope 38 , leads. This traction reduction helps or causes the kite rope to slide 38 from the roles 48-1 to 48-4 . 48'-1 to 48'-4 . 66 . 66 ' in the manner detailed above. The pull rope 30 on the other hand, it is continuously guided safely in the runways of the rollers.

After the slipping of the kite rope 38 To compensate for a tensile force reduction or lots that have occurred in the kite rope and bring the kite rope back to the tension necessary for the infeed, the drive and tensioning device has 32 ( 1 ) on an acceleration device, which is the feed rope 30 accelerated for a short period of time or moved at increased speed until the desired tension in the kite rope 38 is restored. The drive and tensioning device 32 can for this purpose have a Aufholtaster with which the speed of the feeder rope can be raised manually for a short time to a value above the speed of the paper web. After releasing the button, the rope speed drops again to the speed of the paper web or is braked by a brake.

The web speed of the paper web of interest here is the speed suitable for drawing in the paper web, which z. B. between about 20 to 90 m / min and thus is typically significantly lower than the normal operating speed of the paper web. About the drive and tensioning device 32 can the speed of the feeder rope about a ramp to z. B. 10 to 20% relative to the speed of the paper web to be raised.

Thus, the Einziehvorgang can be visually monitored by an operator and the Aufholtaster accordingly can be operated as needed, the Aufholtaster should be an "on-site button", the user at a safe distance from the device, however, in observation position for Device is arranged.

Alternatively, the temporary acceleration of the feeder rope can be done automatically via a control circuit, wherein a measured tension in the kite rope 48 or in the pull-in rope 30 before or in the web turning station 24 or a measured power consumption in the drive and tensioning device 32 is used as a controlled variable.

After the paper web 12 through the web turning station 24 was retracted, the paper web 12 at a constant speed through the remaining stations of the device 10 until reeling 28 drawn. At this point, the kite rope is decoupled from the drawstring, the kite becomes off the paper web 12 separated and the paper web is on the reel 28 rolled up. The pull rope 30 runs over the drive and tensioning device 32 back to the section between unwinding 14 and first commissioned work 16 , The paper web is then completely in the device 10 retracted and the transport speed of the paper web 12 can be increased to operating speed to accommodate normal operation (double-sided coating and drying). During operation, the feed rope becomes 30 at low speed continuously through the device 10 circulated to prevent excessive heating of the feeder rope 30 in the drying facilities 20 . 26 to prevent.

It should be added that the turning bars 40 . 42 . 40 ' . 42 ' as well as the deflection rods 44 . 44 ' preferably for non-contact deflection of the paper web 12 are formed. For this purpose, the rods on their surface on air outlet openings in 4 at reference numerals 70 are indicated. The through the air outlet openings 70 escaping compressed air creates an air bed on the surface of the rods 40 . 42 . 40 ' . 42 ' . 44 . 44 ' leaving a space between paper web 12 and rod surface upright.

To the operation of the turning bars 40 . 42 . 40 ' . 42 ' or the deflection bar 44 . 44 ' to different paper webs 12 To be able to adapt to different width, are in outer sections of the rods, the air outlet openings 70 each covered by magnetic films, which only in 4 at the rear end of the turning bar 42 ' is shown. In fact, preferably have all turning and turning bars 40 . 42 . 40 ' . 42 ' . 44 . 44 ' in each case at both end portions of such magnetic films, to optionally an unnecessary number of air outlet openings 70 cover or expose. These magnetic foils 72 are easy to put on or take off manually and leave only those air outlets 70 free from a paper web 12 actually be swept over.

It should also be added that all the principles described above concerning the guidance of the feeder rope, the formation of Seilumlenkabschnitte, the sliding of the coupling or Drachenbands the control of the drive and tensioning device and in general the assisted threading of a material web also for the Bypassbahnführung 25 ( 1 ) are applicable, if there are turning or turning points there.

The Commissioned works can as a "slot The "-Autragswerke be formed, which a coating medium via a slot nozzle as a curtain fall onto the web, or "Slide Die" jobs can be used, which the application medium from the edge of a sloping plane as a curtain drop. The commissioned works can also optionally for a Single order or for be set up a multiple order.
