Definitions

  • the invention relates to a method for feeding a material web, in particular a paper or board web, on a spool, in particular on an empty or teilbewickelten drum, wherein first a AufzhoustMail the web over a peripheral region of a carrier drum in a reject container, in a resolver or on a Conveyor belt is guided.
  • the invention relates to a winding machine for carrying out the method according to the preamble of claim 16.
  • Such a listing of a material web on a spool is required, for example, at the beginning of a new winding process with a new, still unwound spool ("empty bambour") or to continue an already started winding process after an unwanted or induced web break with an already partially wound spool.
  • the resulting problem with such a method is that the Aufzhoust Shape or the material web has the tendency to unintentionally perform themselves before the cutting on the drum ("self-performance").
  • self-performance of the leader strip or web is influenced by various factors, such as the nip geometry, the surface shape or the proportion of open areas, the reference hardness, the nip force and the paper property.
  • this problem increasingly occurs at high web speeds.
  • the tambour upstream carrier drum is designed as an evacuated drum, in the drum so a negative pressure is generated, which acts via corresponding openings in the drum on the web and this holds on the drum.
  • a self-performance of the web on the spool can be largely avoided. Due to the negative pressure in the carrier drum, however, the decrease of the web for discharge into the reject container is made more difficult.
  • the perforated jacket having a perforated jacket and / or provided with circumferential grooves is sucked from the outside in its part of the circumference not looped by the perforated support band and the material web.
  • this device can also avoid a self-performance of the material web on the spool, but the perforated support belt is subject to wear and must therefore be replaced at certain time intervals.
  • the suction of the more expensive in the production cost of the carrier drum with a perforated shell and / or with circumferential grooves increased running costs associated with it.
  • German Offenlegungsschrift DE 198 48 806 A1 directed.
  • This document discloses a method for applying a material web to a spool, in which the beginning of the material web to be fed is connected upstream of a spool Drum guided around and before being fed onto the spool of a preparation station such as a rejects dissolver is supplied. In this case, the material web is kept away from the tambour by means of blown air before being placed on the drum.
  • Disclosed is also an apparatus for carrying out the method with a transverse to the web running direction Blasbalken with at least one outlet opening for the blown air, means for supplying blown air to the blowing bar and control means for controlling the introduction of blown air.
  • the invention is therefore based on the object , a method of the type mentioned in such a way that the AufzhoustMail is first performed reliably and controlled to the reject container, in the resolver or on the conveyor belt and that a Daufch the same on the spool regardless of the respective Position is prevented as much as possible, without thereby complicating the web removal of the drum before the drum.
  • a suitable winding machine for carrying out the method should be specified.
  • the medium may be a liquid, a mixture of liquids, a gas, a mixture of gases, a condensing gaseous medium, in particular steam, and the like.
  • This inventive method ensures that the Aufzhoust Shape stabilized, that is reliably and controlled over the partial circumference of the carrier drum is performed. This increases the overall reliability and consequently the runability of the winding machine. Furthermore, the transfer time of the material web is reduced to the spool and scrap production is largely avoided. There is also the possibility of retrofitting existing winding machines without much effort, the installation and operating costs are low, both new installations and retrofits.
  • the introduction of the at least one medium is preferably carried out in two ways: the carrier drum is sprayed in the area in which the AufzhoustMail runs up on them, at least during the leadership of the AufzhoustMails or the AufzhoustMail is sprayed at least during its leadership over the peripheral region of the carrier drum. Both possibilities fully provide the advantages mentioned above.
  • the at least one medium is applied or applied with at least one preferably controllable spray device which comprises at least one, preferably a plurality of spray nozzles. This provides the advantage of increased process reliability with ideal introduction of the at least one medium.
  • the release strip is preferably detached from the carrier drum by means of at least one scraper which can preferably be adjusted, in particular by a blade scraper and / or air scraper, which can be applied to the carrier drum constantly or only during the threading.
  • the scraper can also be provided with a collecting tray.
  • the first possibility is characterized in that during the guidance of the AufzhoustMails over the peripheral region of the carrier drum of the reel is applied to the carrier drum with formation of a nip between the carrier drum and the spool, that then drove the AufzhoustMail to a desired width of the web wide is and then that the web is severed and started with the winding of the web on the spool to a winding roll.
  • the second possibility is characterized in that during the guidance of the AufzhoustMails over the peripheral region of the carrier drum it is driven wide to a desired width of the web, that thereafter the drum is applied to the carrier drum in forming a nip between the carrier drum and the drum and that then the material web is severed and started with the winding of the web on the spool to a winding roll.
  • Both options have in common that they allow a fast and process-safe AufGermanvorgang the web on the spool at the lowest possible reject rates and also favor.
  • the spreading of the leader strip to a desired width of the material web is preferably carried out by means of at least one lace cutter and the desired width of the material web is generally the entire web width.
  • the cutting of the material web takes place only after it meets at least one desired quality feature and / or production feature.
  • Desired quality features of the web are, for example, the Surface roughness, the shrinkage transverse profile and the fiber orientation, whereas desired production characteristics of the web are, for example, the web speed, the web width or the production quantity.
  • a winding machine with the characterizing features of claim 16 is proposed.
  • at least one, preferably a plurality of spray nozzles having and preferably controllable / sprayable spray device is provided which introduces at least one medium between the carrier drum and the Aufzhoust Shape at least during the leadership of the AufzhoustMails on the peripheral region of the carrier drum.
  • the medium may be a liquid, a mixture of liquids, a gas, a mixture of gases, a condensing gaseous medium, in particular steam, and the like.
  • the at least one spray device is preferably arranged in such a way that the carrier drum is sprayed with at least one medium at least during the guidance of the leader strip in the region in which the leader strip runs onto it and / or that the leader strip is sprayed over the peripheral region at least during its guidance Carrying drum is sprayed with at least one medium.
  • the spray device preferably comprises at least one feed line, a shut-off device, a volume adjuster and a plurality of spray nozzles.
  • the winding machine further preferably comprises at least one preferably engageable scraper, in particular a blade and / or air scraper for releasing the AufzhoustMails of the carrier drum, wherein it has a scraper width which is at least equal to the width of the AufzhoustMails or at least equal to the width of the carrier drum is.
  • the winding machine described below is generally for winding a running fibrous web, such as a paper or board web used.
  • the winding machine can be arranged at the end of a machine for producing or finishing a moving fibrous web to wind the finished running fibrous web to a winding roll. But the winding machine can also be used to roll finished winder rolls. Purely by way of example, it is assumed that this is a winding machine for winding a continuous fibrous web.
  • FIG. 1 shows a schematic and perspective view of a winding machine 1 for winding a material web 2 on a spool 3. It includes a designated as Anpresstrommel or support roller carrier drum 4, which is either rigidly mounted or along an imaginary means of a pressing device, not shown, and which is driven by a drive, not shown, in particular a center drive.
  • the different storage and movement types for the carrier drum 4 are particularly in the European Patent Application EP 0 941 955 A2 disclosed; its content is hereby made the subject of this description.
