Definitions
- the invention relates to a method for transferring a material web, in particular a paper or cardboard web, preferably running over a partial area of a winding roller, to a new winding core.
- the invention relates to a method for transferring a material web, in particular a paper or cardboard web, preferably running over a partial region of a winding roller, to a new winding core, in particular an empty drum, which forms a nip with the winding roller, preferably in at least one edge region of the Material web is formed at least one transfer strip by means of at least one separating device, preferably a transverse separating device, arranged in front of the nip in the running direction of the material web.
- the invention also relates to a device for carrying out such a method with at least one separating device, preferably a transverse separating device.
- the invention also relates to a respective winding machine for carrying out such methods.
- Such methods for transferring a material web are used, for example, in the area of a reeling device of a machine for paper or cardboard production, a coating machine, a slitter winder or an equivalent machine, in order to successively move the material web without interrupting the production process, i.e. without switching off the paper or cardboard machine on several empty winding cores, which are also referred to as empty reels, or sporadically around the material web, i.e. after an tore the paper or cardboard web or after starting the paper or cardboard machine to wind up on a preferably empty winding core.
- a middle part of the material web a so-called transfer strip
- the transfer strip is provided on the top side, that is to say on the side facing the empty reel, with an adhesive medium by means of an adhesive supply device and is glued to the surface of the empty reel.
- the transfer process is completed by the movement of the two cutting devices in the direction of the respective web edge.
- This method therefore presupposes that the adhesive medium has the ability to tear through the transfer strip completely and reliably at the latest when it leaves the nip.
- US Pat. No. 5,954,290 A also discloses a device for transferring a running paper web to a new winding core. It is provided that a high-strength separating tape, the length of which is a multiple of the width of the material web, can be inserted directly into the nip in an edge region of the paper web in such a way that its beginning connects to the new winding core. The separating tape then spirals onto the new winding core, tearing through the entire web of material at the same time and transferring it to the new winding core.
- German patent specification DE 35 15 519 C2 describes a method in which a transfer strip is formed, but its connection to the preceding web is completely separated before the nip.
- the question also arises here how the web "bound to nothing" can be reliably transported to the nip and performed on the new winding core?
- the object of the present invention is therefore to provide a method and a winding machine of the type mentioned at the outset which enable an optimal transfer of a running material web to a new winding core with high process reliability, process efficiency and low investment and process costs and the disadvantages of the known state of the art avoid technology entirely.
- the method should be able to be used for all known types of reeling devices and a wide range of material webs equally.
- this object is achieved in a method in that at least one initial separating piece is introduced between the material web and the winding roller in such a way that an area of the introduced initial separating piece is not covered by the material web such that the in- itial separating piece after reaching the nip formed by the winding roller and the new winding core is at least temporarily connected to the new winding core in the uncovered area, and that at the latest at the point of run-off of the material web from the new winding core, at least separation of the material web is effected by the initial separating piece and / or is made possible, as a result of which a new web start which is bound to the initial separating piece and the new winding core is formed.
- the defined and safe formation of a new, bound web start ensures an absolutely clean start of the wrap, which is one of the most important prerequisites for an optimal wrap build-up and a small amount of rejects.
- the process which comprises just a few process steps, achieves the highest reproducibility and the associated reliability when transferring running material webs at extremely low investment and process costs.
- At least one initial separating piece is introduced at least in an edge region of the material web. And that an area of the respectively inserted initial separating piece is not covered by the material web, that the initial separating piece is connected to the new winding core after reaching the nip, that at the latest at the point of departure of the material web from the new winding core, the material web is essentially completely through the respective initial separating piece is severed, whereby a new, to the ini tial separator and the new winding core bound web start is formed.
- the width of the beginning of the web transferred to the new winding core is preferably increased by means of the separating device in such a way that the entire material web is transferred to the new winding core.
- the at least one initial separating piece according to the invention can also be introduced in any area of the material web to be transferred to a new winding core.
- the introduction of the initial separator is therefore not limited to the at least one edge area.
- Another area can be, for example, in the middle of the material web, the material web preferably having to be processed accordingly in advance.
- the object is achieved in a winding machine in that at least one dispensing device for introducing at least one initial separating piece is arranged between the material web and the winding roller in such a way that the initial separating piece can be introduced essentially directly or indirectly between the material web and the winding roller ,
- the winding machine in at least one edge region of the material web, there is at least one dispensing device, by means of which at least one initial separating piece can be inserted between the material web and the winding roller, that the respective initial separating piece can then be connected to the new winding core in its area not covered by the material sheet after the nip has been reached, that the material web can be connected through the initial separating piece forming a new web start bound to the initial separator and the new winding core and that the width of the respective new web beginning can be changed by means of the separating device in such a way that the entire material web can be transferred to the new winding core.
- This variant is particularly advantageous for relatively wide or thick material webs, for example cardboard webs. In this way, the tendency to form a conical coil, which is generally undesirable, is minimized. Due to the fact that the respective separating devices and dispensing devices can also be used independently of one another for transferring the material web, this configuration of the winding machine provides system-related redundancy and, as a result, optimum process reliability.
- the arrangement of the at least one dispensing device according to the invention for introducing at least one initial separating piece between the material web and the winding roller is, however, not only restricted to the at least one edge region of the material web.
- the dispensing device can also be introduced in any area of the material web to be transferred to a new winding core.
- the introduction of the initial separator is therefore not limited to the at least one edge area.
- Another area can be, for example, in the middle of the material web, the material web preferably having to be processed accordingly in advance.
- the previously specified object is achieved in a method in that at least one opening, in particular a slot or an insertion surface is produced in the area of the material web, preferably by means of a first separating device, that in the area of the insertion area at least one initial separating piece is introduced between the material web and a winding roller such that an area of the introduced initial separating piece does not separate from the material web is covered that the initial separating piece is at least temporarily connected to the new winding core after reaching a nip formed by the winding roller and the new winding core, and that at the latest at the point of run-off of the material web from the new winding core, a separation of the material web by the initial separating piece is effected and / or made possible, whereby at least two new web beginnings bound to the initial separating piece and the new winding core are formed.
- the defined and safe formation of at least two new, bound web starts ensures an absolutely clean winding start, which is one of the most important prerequisites for an optimal winding build-up and a small amount of rejects.
- the process which comprises just a few process steps, achieves the highest reproducibility and associated reliability when transferring running material webs to new winding cores at extremely low investment and process costs.
- the introduction surface in the area of the material web is preferably generated by means of a first separating device by producing at least one discharge strip. The generation of such an insertion surface creates, among other things, the technological advantage that the initial separating piece can be transferred to the new winding core better and more reliably because of the larger surface.
- the introduction surface is created in the middle of the material web and / or that at least one introduction surface is created in the central region of the material web lying between the two edge regions and / or that at least one introduction surface, preferably two introduction surfaces, in the is generated in both edge areas of the material web.
- the generation of the at least one insertion surface depends fundamentally on the respective application, but each individual configuration has certain advantages, such as, for example, avoiding a so-called winding carrot.
- the at least one stripping strip having a strip width in the range from 10 mm to 250 mm, in particular from 25 mm to 100 nm, is produced by means of a first separating device, such as a cutting element that has been tried and tested in practice, the strip width in turn being dependent on the respective application.
- the discharge strip by means of at least one discharge device having a negative pressure of 0.01 bar to 0.2 bar, preferably 0.05 bar to 0.1 bar, directly after it Generation is dissipated.
- a negative pressure of 0.01 bar to 0.2 bar preferably 0.05 bar to 0.1 bar
- directly after it Generation is dissipated.
- an initial separating piece is used, which is provided in the area not covered by the material web with means with which at least a temporary, at least temporarily, sufficient when the nip formed by the winding roller and the new winding core is reached by the initial separating piece fixed connection between the initial separator and the new winding core is established.
- an adhesive, vulcanization, Velcro fastener, suction button, form-fit, frictional or welded connection or a magnetic or electrostatic connection with the new winding core is produced.
- All of these resources have in common that they are characterized by a good cost-benefit ratio and also have above-average process reliability.
- an initial separating piece which has at least one adhesive area in the area covered by the material sheet, in order to establish at least one temporary connection between the material sheet or between the new beginning of the sheet and the initial separating piece.
- an initial separating piece with a thickness in the range from 0.5 mm to 0.05 mm, preferably in the range from 0.25 mm to 0.1 mm, is preferably used. This thickness ensures that there are no markings in the material web due to the initial separator.
- an initial separating piece designed as a shaped piece which consists of a plastic, a metal, a textile material, a tear-resistant fibrous material, in particular paper, or at least one material combination.
- This shaped piece makes the handling of the initial separating piece much easier, but without negatively influencing the transfer of the running material web to a new winding core.
- the initial separator can also be designed as a preferably easily detachable part of a carrier.
- the initial separating piece can be attached to at least one carrier by means of a relatively easily detachable connection between the material web and the winding roller, the ideally after the nip leaving the nip, the at least one carrier is neither carried with the new web start nor with the new winding core ,
- the initial separating piece is provided with means for punching, cutting, perforating or embossing the material web, with which the material roll is weakened or even severed by the new winding core at the latest at the point of run-off of the material web.
- the initial separating piece is introduced essentially directly between the material web and the winding roller by means of at least one dispensing device.
- the initial separating piece is introduced essentially directly into the nip by means of at least one dispensing device, or it is introduced indirectly between the material web and the winding roller by means of at least one dispensing device, or it is first applied on the underside of the material web and then introduced by means of the material web between the material web and the winding roller or it is first applied to the outer surface of the winding roller in the case of a temporary connection and then introduced by means of the winding roller between the material web and the winding roller, the temporary connection being made by means of at least one adhesive surface, by means of electrostatic forces magnetic forces, by means of vacuum application of the winding roller, by means of Velcro or by means of at least one suction button coupling. All of these locations and options mentioned have the aim of transferring the running material web to a new winding core as quickly and reliably as possible.
- the widths of the web starts transferred to the new winding core are advantageously increased by means of a second separating device in such a way that the entire material web is transferred to the new winding core.
- the second separating device is moved in a plane approximately parallel to the material web relative to the material web, preferably to the ' ⁇ esi essentially perpendicular to the running direction of the material web, so that oblique separating lines are generated.
- At least at the part of the material web that is at least a part of the material web is substantially completely cut through by the initial separating piece by the initial separating piece. At least at the part of the material web, at least a part of the material web is preferably substantially completely cut through at the point of departure of the material web along a separation contour specified by the initial separating piece.
- the object is achieved in a winding machine in that a first separating device for creating at least one opening, in particular a slot or an insertion surface, is arranged in the region of the material web and in that at least one dispensing device for introducing at least one initial separating piece between the Material web and the winding roller is arranged such that the initial separator in can be introduced substantially directly or indirectly between the material web and the winding roller.
- the delivery devices are arranged such that the initial separating piece is first applied to the underside of the material web and can then be inserted between the material web and the winding roller by means of the material web, or that the initial separating piece is first applied to the outer surface of the winding roller with a temporary connection and can then be introduced between the material web and the winding roller by means of the winding roller.
- the initial separating piece has at least one adhesive area in the area that is both covered and not covered by the material web. This creates the possibility that the initial separating piece enters into an ideal connection both with the material web and with the outer surface of the new winding core.
- the initial separating piece has at least one separating contour in the area covered by the material web, which is preferably designed neither in the running direction nor transverse to the running direction of the material web.
- This separation contour favors the actual separation process and thus increases process reliability for transferring the running material web to a new winding core.
- the initial separator ideally has a thickness in the range from 0.5 mm to 0.05 mm, preferably in the range from 0.25 mm to 0.1 mm, and is in the form of a molded part made of a plastic, a metal, or a textile material , a tear-resistant fibrous material, in particular paper, or from at least one Material combination formed, is formed as part of a carrier and / or is attached to at least one carrier before being introduced between the material web and the winding roller by means of a relatively easily detachable connection.
- These possible properties of the initial separator mentioned also favor the actual cutting process and thus increase the process reliability for transferring the running material web to a new winding core.
- the first and / or the second separating device are in the region of the winding roller and / or in the direction of travel of the material web in front of the winding roller in the region of a free path and / or in the direction of travel of the material web in an area in which the material web has at least one roller upstream of the winding roller touched, arranged.
- first and / or the second separating device are arranged on the top and / or bottom of the material web and they are arranged in a common assembly with preferably common components.
- the second separating device is arranged in the areas of the material web which are not part of the beginning of the web and are to be separated.
- the initial separator forms the last device and / or the last element - as seen in the direction of travel of the material web - for separating and / or transferring the material web to the new winding core.
- the object is achieved in a method in that at least one initial separating piece is introduced directly or indirectly between the at least one transfer strip and the winding roller by means of at least one dispensing device in such a way that an area of the inserted initial separating piece is not covered by the transfer strip that after the nip formed by the winding roller and the new winding core has been reached, the initial separating piece is at least temporarily connected to the new winding core in the uncovered area, and that at least at the point at which the material web runs off from the new winding core, the initial separating piece at least separates the transfer strip and / or is made possible, as a result of which a new path start which is bound to the initial separating piece and the new winding core is formed.
- the defined and safe formation of a new, bound web start ensures an absolutely clean start of the wrap, which is one of the most important prerequisites for an optimal wrap build-up and a small amount of rejects.
- the process which comprises only a few process steps, is the most reproducible and therefore connected reliability achieved when transferring running material webs with extremely favorable investment and process costs.
- a transfer strip is formed by means of at least one separating device known from the prior art and arranged in front of the nip in the running direction of the material web, preferably a transverse separating device, that For each transfer strip, an initial separator between the transfer strips and the winding roller is introduced directly or indirectly by means of a dispensing device in such a way that an area of the respectively inserted initial separator is not covered by the transfer strip, so that the initial separators are connected to the new winding core after reaching the nip at the latest at the point of flow of the material web, the transfer strips are essentially completely severed by the respective initial separating pieces from the new winding core, as a result of which a new, each initial separating piece, to the initial separating piece and the new winding core bound web start is formed and that the width of the web beginning transferred to the new winding core is increased by means of the separating device such that the entire material web
