Definitions

  • the invention relates to a method for transferring a preferably over a portion of a winding roller material web, in particular a paper or board web, on a forming a nip with the winding roller new winding core, in particular an empty bobbin, preferably in at least one edge region of the web at least one transfer strip is formed by means of at least one before the nip in the direction of the web arranged separating device, preferably a cross-cutting device.
  • the invention also relates to a winding machine for carrying out such a method with at least one separating device, preferably a cross-cutting device.
  • Such methods of transferring a web of material are used, for example, in the area of a reel of a paper or board making machine, a coater, a slitter or an equivalent machine to the web without interrupting the manufacturing process, that is, without switching off the paper or board machine, one after the other on several empty hubs, which are also referred to as empty cores, or to spool the material web, that is, after a demolition of the paper or board web or after starting the paper or board machine to wind on a preferably empty core.
  • German Offenlegungsschrift DE 42 08 746 A1 discloses a method for changing bobbins, in which a material web supplied continuously to a winding roller is transferred to a new bobbin (empty bobbin) that is in contact with the winding roller.

  • the transfer strip is on the upper side, that is provided on the empty bobbin side facing, by means of a Klebstoffzu fürvoriques with an adhesive medium and adhered to the surface of the empty beater. The transfer operation is completed by the movement of the two cutting devices in the direction of the respective web edge.
  • the adhesive medium has the ability to completely and reliably tear through the transfer strip at the latest when leaving the nip.
  • a disadvantage of this method is the design complexity and the extremely large number of components and groups. Also the temporal synchronization and Reproducibility of the individual process steps represent an uncertainty factor in the transfer of paper webs. The process is also absolutely unsuitable for transferring paper webs with high tensile strength, such as plastic sheets and cardboard.
  • German patent application cited above dispenses with the use of mechanical circular knives, which in practice bring many disadvantages, and instead provides the water jet as a separation medium, with which the material web can be cut both before and directly on the winding roller.

It is envisaged that in a peripheral region of the paper web, a high-strength separating belt, the length of which is a multiple of the material web width, so directly into the nip can be introduced that its beginning connects to the new hub. Thereafter, the separating tape winds spirally on the new hub, wherein it tears the entire web at the same time and transferred to the new hub.
  • US Pat. No. 4,444,362 A discloses a method in which, in principle, no transfer strip is present, since the web start is completely formed by the cross-cutting devices before the winding roller.

  • the question also arises as to how the "bound to nothing" web start can reliably be transported to the nip and listed on the new winding core.

  • a means used to form the new web start has a smaller width than the width of the material web.
  • the agent causes edge-side joining of the material web to the winding core, wherein the material web is subsequently separated by the action of shearing forces when creating a new web start.
  • German Offenlegungsschrift DE 42 08 746 A1 further discloses a method and a device for changing bobbins, in which a continuously fed to a reeling drum web is wound onto a new bobbin.
  • the following method steps are provided: bring the new spool, which is held with one arm in a waiting position, in contact with the reeling drum; Cutting the middle part of the web with two Cutting devices along two approximately parallel cutting lines in the direction of travel of the web at a location which lies above the reeling drum in the direction of travel of the web; Supplying an adhesive in a region between the cutting lines and adhering the adhesive to a surface of the new coil; and moving the two cutters toward the respective web ends to cut the web into a triangular shape.
