Description

The The invention relates to a method for transferring a running material web, in particular a fibrous web, to a new winding core, wherein the material web preferably over a peripheral region of a preferably displaceable and with a to be produced winding roll a winding gap forming carrier drum guided and then on a winding core is wound to the wound roll to be produced, wherein the new hub preferably immediately before reaching a predetermined Wickelrollendurchmessers in the looped by the web Peripheral region of the carrier drum to the same with training a new winding nip is brought and wherein the web after Training the new winding nip between the new hub and the carrier drum is severed by means of at least one separating device and an adhesive medium between the layers of the web is introduced by means of at least one applicator device.

Farther The invention relates to a winding machine according to the The preamble of independent claim 9, in particular for carrying out the inventive Method is suitable, and a winding core according to the The preamble of independent claim 15, in particular to Implementation of the method according to the invention suitable is.

Such transfer procedures and winding machines are used, for example, in paper or board production used to make the finished and running paper or board web without interrupting the manufacturing process, that is without switching off the paper or board machine, one after the other several hubs, which are also referred to as empty hulls, to wind up bobbins. Also, they can serve to wrap an already finished wound roll.

there must be taken care of by the severing the material web resulting new beginning of the material web process reliable, fast and fed virtually neutral to the new hub to make a new roll on this afterwards. Further it is of importance, both in terms of cleanliness and the Runnability of the winding machine that the last layers of the on the produced winding roll wound-up material web endverklebt become. The Endlagenverklebung is the emergence of a disturbing Fetzenflugs avoided during braking of the produced winding roll, at least but noticeably reduced. And moreover, the number of loose outer layers, which assume a value of up to 50 loose outer layers can significantly reduced on the produced winding roll.

An aforementioned method for transferring a running material web, in particular a fibrous web, to a new winding core is known, for example, from the German publication DE 100 85 234 T1 known. In this method, the adhesive or the like is applied to the surface of the finished roll. While the range and amount of application will ensure that the final layers of webs wound onto the formed reel are ideally end-bonded, the amount of adhesive required is very large. The disclosed method thus entails the disadvantage of an extreme consumption of adhesives and thus very high operating costs.

Farther is provided in one embodiment that the adhesive immediately before the winding nip between the carrier drum and the to be produced wound roll on the surface of the produced Winder is placed. For this purpose, a the adhesive applying Part of a collection device, in particular a so-called gooseneck attached. Does it come in this embodiment now to a unexpected material web tear, so the adhesive can on the surface of the Carrying drum, which then disadvantageously is contaminated. The elimination of this contamination is in the Usually a usually long-lasting production loss entail.

Furthermore, from the German Offenlegungsschrift DE 103 09 049 A1 a method for transferring a moving material web known. In this method, the material web is separated by a single parting line and during the separation of the material web, an adhesive is applied to the material web, by means of which the material web is connected to a new winding core. In this case, the adhesive is applied to the material web in an area at least partially sweeping over the parting line. The applied adhesive can in this case cause a final layer bonding of the last material web layers on the wound roll produced, this Endlagenverklebung due to the successful passage of the adhesive through the new winding nip formed by the new winding core and the winding drum probably no large and thus sufficiently process-safe bonding will effect. Consequently, the last material web layers, at least during braking of the produced winding roll can loosen again and thereby possibly cause a disturbing shred flight.

Furthermore, from the German patent application DE 103 43 448 A1 a method for preparing a winding of a moving material web on a winding drum for further processing known. In this process, at least an adhesive region is produced on the outer layer by means of at least one application device. The applicator is located in the vicinity of the winding drum, so in the free train of the web in front of the winding drum. This site of action of the applicator requires on the one hand increased investment and operating costs, on the other hand, the gluing possibilities and variants are very limited due to the limited space available. Furthermore, in this method, the formation of the free train in the material web, so the resolution of the formed between the winding drum and the carrying drum winding nip of disadvantage. This release of the winding gap provides the risk of air pockets between the individual layers of the web and the non-maintenance of the "wrapped" web tension during the transfer process. Thus, the use of an expensive and elastic coating having Luftabquetschwalze is essential.

And from the German utility model DE 20 2004 009 144 U1 is a winding machine for transferring a moving material web known. In this case, it is provided that at least one adhesive arrangement in the direction of travel of the material web is arranged immediately after the discharge point of the material web from a carrier drum. Also in this disclosed winding machine turn out the disadvantages just mentioned, so increased investment and operating costs, limited adhesive options and variants and possible use of an expensive Luftabquetschwalze.

It So is the object of the invention, both a method and a Winding machine of the aforementioned types in such a way, that the aforementioned disadvantages of the prior art noticeable reduced, preferably even completely avoided. In particular, the external matters committee should also be reduced and achieved a high-quality construction of the winding roll become. In addition, the best conditions for an optimal Runnability and favorable investment and process costs be given.

Further should also be a hub of the type mentioned in such a way developed be so that he in particular to carry out the inventive Method is suitable.

These The object is achieved in a method of the type mentioned in the present invention, that the adhesive medium in the direction of the web before the new, between the new hub and the reel drum trained winding nip on the top and as at least one strip on the material web by means of the at least one application device is applied so that it is the new winding nip in one Passes through area in which the new hub with at least one radially arranged on the circumference recess is, wherein the at least one recess is vorgese hen, in that the adhesive medium applied to the web of material passes through the new winding nip untouched.

The inventive object is in this way completely solved.

By the combination of the characteristic features, so the upper side Applying at least one strip of the adhesive Medium on the web and the provision of at least one the circumference radially arranged recess on the new hub, the possibility is created that on the material web applied adhesive medium the new winding nip untouched passes. Thus, only small Quantities of adhesive medium virtually lossless to an effective Endverklebung the last layers of the wound roll produced contribute coiled material web. The term "strip" defines in this case only a maximum area or a form of the applied adhesive medium; so can the adhesive medium, for example, as one skilled in the art known "caterpillar" are applied.

moreover is the application of the adhesive medium in the direction of travel the web before the new, between the new hub and the winding drum formed winding nip of process technology Advantage. So on the one hand between the winding roll and the Carrying drum trained winding nip can not be opened on the other hand, there is sufficient space for the application of the adhesive medium.

there it is of particular advantage if the adhesive medium in front of the circumferential area of the carrier drum, which is looped around by the material web the material web is applied. Because this can be complete Avoid that adhesive medium on the surface the carrying drum can get, whether due to an unexpected Material web break or due to a wrong control of Applicator.

The adhesive medium generally results in an adhesion comprising adhesive forces at the contact surfaces of two different or the same substances by molecular forces. The substances may be in solid or liquid state. In the field of adhesives, the adhesion of adhesive layers to the adherend surfaces is understood to be adhesion. The processes of adhesion are not fully understood. They are particularly difficult, because the dependencies between the adhesive systems and the different Fügeeteiloberflä are very complex.

So can in the context of the present invention, the adhesive Medium water, a preferably water-soluble liquid adhesive, especially starch, a two-component adhesive, a hot melt adhesive (Hotmelt) or one example by UV radiation activatable Be adhesive. Of course, the adhesive can Medium but also a preferably water-soluble adhesive tape, in particular a ready-made adhesive strip or a punched out Be adhesive tape rondelle.

In a first preferred embodiment, the adhesive Medium in at least two, preferably more and preferably equally distributed, in particular symmetrically to the center of the web arranged strips applied to the web. So can the process reliability with regard to the final bonding of the last one Layers of wound on the produced winding roll material web be substantially increased and a possible web width Endverklebung produced without any disadvantages in terms of winding technology become.

In order to also a sufficient adhesion between the last layers the wound on the produced wound roll web is prepared, the adhesive medium as at least a strip with a strip width in the range of 1 to 50 mm, preferably from 1 to 30 mm, in particular from 1 to 5 mm, to the Applied material web. Moreover, a generated for This strip width required recess width still no "suppression" and Thus, no core committee in the first layers of the new Winding core wound material web. The maximum allowed, yes harmless recess width depends in for the person skilled in the known manner of the material web type, the winding core diameter and the winding roll diameter.

The Adhesive medium can be used in different time periods and -dauern and strip-like in various application locations be applied to the web. This is how it is done at least during and / or in the region of the transection the web as at least one strip on the web applied. If the adhesive medium, for example, temporally significantly before the material web is severed onto the same applied, so is just over several layers away one Endblattverklebung the web on the wound roll to be produced generated. Moreover, by an exact determination of the Time ranges and durations on the one hand and the place of application on the other hand an optimal Endblattverklebung and a safe transfer the material web on the new hub due to the temporary Use of the adhesive medium can be achieved.

In Another preferred embodiment is in a first step before applying the adhesive medium the position of at least one attached to the new hub Recess determined by means. In a second Step then becomes the adhesive medium as at least one Strip in the area of at least one determined and on the new winding core attached recess on the web applied. This procedure ensures that the spatial coordination between the place of application of the adhesive Medium and attached to the new hub core recess continuously given and thus any operational tolerances, manufacturing tolerances, such as an axial clearance in the new hub, and different Conditions, such as different tolerances in the reel magazine, with the transport rails or with the transport levers, no negative Influence the procedure.

The Position of at least one attached to the new hub Recess is preferably by means of at least one optical, capacitive or inductive sensor, since these types of sensors in similar Use cases in the field of a winding machine already have proven to be best.

Of the corresponding sensor is of course connected to an evaluation unit, in turn with the control unit for the Winding machine is connected. The control unit for The winding machine can in turn optionally with a parent System, such as a process control system for the machine for producing the fibrous web to be connected.

In It depends on the realized wrapping concept also possible that before the formation of the new winding nip between the new hub and the carrier drum to be produced Winder from the carrier drum when the winding gap is released and moved away when forming a free train in the web becomes. Thus, the new hub along a larger Peripheral area of the carrier drum in forming the new winding nip is brought. However, that could be disadvantageous necessary use of an expensive Luftabquetschwalze.

Furthermore, the material web is severed by means of the at least one separating device arranged in the region or after the application position of the adhesive medium, preferably a cross-cutting device, in particular a water-jet cross-cutting device. Such a separator generally ensures good to very good release properties, such as separation speed, release quality and the like. Depending on the number of separating devices, different separating contours can be realized: a dividing line across the width of the web, two dividing lines preferably crossing in the middle region of the material web and extending to the opposite web edge or two spaced apart from each other in the middle region of the material web and extending to the same web edge dividing lines.

The The object of the invention is in a winding machine of the aforementioned type according to the invention thereby solved that the at least one order device for the adhesive medium is provided so as to provide the Adhesive medium in the direction of the material web in front of the new, formed between the new hub and the carrier drum Winding nip on the top and as at least one strip on the web applies so that it passes through the new winding nip in an area in which the new hub with at least one at the periphery radially arranged recess is provided, wherein the at least a recess is provided such that the on the material web applied adhesive medium the new winding nip untouched passes.

These winding machine according to the invention is suitable in excellent manner for carrying out the inventive Method, so that ultimately the aforementioned invention Benefits arise. The term "strip" defines this only a maximum area or a shape the applied adhesive medium; so can the adhesive Medium, for example, as a known to the expert "bead" applied become.

In a first preferred embodiment, the new Winding core according to the applied strips of adhesive Medium at least two, preferably several and preferably equally distributed, in particular symmetrically arranged to the middle of the material web Recesses on. So can the process security regarding the Endverklebung the last layers of the wound roll produced wound material web are substantially increased and a as far as possible web-wide final bonding without any winding technological Disadvantages are generated.

And depending on the stripe width of the corresponding Strip of adhesive medium, the at least one at the new hub attached recess a recess width in the range of 1 to 50 mm, preferably 1 to 30 mm, in particular from 1 to 5 mm. Moreover, such generates Aussparungsbreite still no "suppression" and Thus, no core committee in the first layers of the new Winding core wound material web. The maximum allowed, yes harmless recess width depends in for the expert known manner also of the web type, the Core diameter and the winding roll diameter from.

Further has the at least one attached to the new hub and a recess having recess in a preferred Embodiment a recess depth in the range of 0.1 to 10 mm, preferably from 0.1 to 7 mm, in particular from 0.1 to 5 mm, wherein the recess bottom preferably with a coating, in particular a silicone or Teflon coating is provided. With such a coating is a possible, however avoided unwanted bonding to the new hub. As a general rule the recess depth should be such that the local order of the adhesive medium finds enough "ground clearance". With regard to the cost of the new hub you will strive to get along without a coating of the recess floor. However, a coated recess base reduces the required Recess depth considerably. Thus, the recess in the winding core for example, completely with the described coating be filled, so that ultimately no recess is available.

In Another preferred embodiment is preferred in the area of the new, with the carrier drum a new winding nip forming winding core at least one means for determining the position of the at least one attached to the new hub Recess provided. The at least one application device for the adhesive medium is then preferably at least a device positionable such that the adhesive Medium as at least one strip in the region of at least a determined and attached to the new winding core recess the material web is applied. This procedure ensures that that the spatial coordination between the place of application of the adhesive medium and attached to the new hub Recess is continuously given and thus any operational Tolerances, manufacturing tolerances and other conditions no can exert a negative influence on the winding machine.

The device for determining the position of the at least one recess attached to the new winding core preferably comprises at least one optical, capacitive or inductive sensor, since these types of sensors have already proven their worth in similar applications in the area of a winding machine. The corre sensor is of course connected to an evaluation unit, which in turn is connected to the control unit for the winding machine. The control unit for the winding machine can in turn optionally be connected to a higher-level system, such as a process control system for the machine for producing the fibrous web.

The inventive object is in a winding core of the aforementioned type according to the invention thereby solved that the main body with at least one is provided on the circumference radially arranged recess which a Saw width in the range of 1 to 50 mm, preferably 1 to 30 mm, in particular from 1 to 5 mm, and a recess depth in the range of 0.1 to 10 mm, preferably from 0.1 to 7 mm, in particular of 0.1 to 5 mm.

This inventive winding core is suitable in excellent Way to carry out the inventive Method, so that ultimately the aforementioned invention Benefits arise.
