Definitions

  • the invention relates to a method in connection with a slitter-winder of a fibrous web for attaching the end of the web of each web roll to the surface of the roll, in which method the web rolls are wound supported by at least two lower support elements, and in which, during winding, the web is brought onto the roll via the first support element and, upon completing the winding, each of the completed rolls is transferred by a pushing device.
  • the invention also relates to an arrangement in connection with a slitter-winder of a fibrous web for attaching the end of web rolls to the surface of each roll, which arrangement comprises two support elements arranged to support the web rolls from below, and a web roll removal device arranged to receive the web rolls from the second support element, and a pushing device arranged to push each web roll of a web roll group simultaneously in the machine direction, and a web end attachment unit for attaching the end of the web to the web roll.
  • paper is manufactured in machines, which together constitute a paper-manufacturing line, which can be hundreds of metres long.
  • Modern paper machines can produce over 450 000 tons of paper per year.
  • the speed of the paper machine can exceed 2000 m/min and the width of a paper web can be more than 11 metres.
  • the manufacture of paper takes place as a continuous process.
  • the paper web completing in the paper machine is wound by a reel-up around a reeling shaft, i.e. reel spool, into a parent roll, the diameter of which can be even more than 5 meters and weight more than 160 tons.
  • the purpose of winding is to modify the paper web manufactured as planar into a more easily processable form.
  • the continuous process of the paper machine breaks for the first time and shifts into periodic operation. This periodicity is tried to be made with efficiency as good as possible in order not to waste already done work.
  • the web of the parent roll produced in paper manufacture is so-called full-width and even more than 100 km long so it must be slit into partial webs with suitable width and length for customers and wound into so-called customer rolls before shipping from the paper mill.
  • This slitting and winding up of the web takes place, as known, in an appropriate separate machine, i.e. a slitter-winder.
  • a slitter-winder From prior known art are known different types of slitter-winders; in king roll slitters, partial web rolls are wound on two king rolls and, in center drum winder, the web rolls are wound supported from their centres.
  • a full-width parent roll is unwound, the web is slit on the slitting section into several narrower partial webs, which are wound up on the winding section around winding cores, such as spools, into customer rolls.
  • winding cores such as spools
  • the slitter-winder is stopped and the web rolls, i.e. the so-called set is removed from the machine. Then, the process is continued with the winding of a new set.
  • the station needs a separate mobile beam, onto which the taping- or gluing device is attached. Further, the frame structure of the beam is needed.
  • WO2007/060293 A2 discloses a method in connection with a slitter-winder of a fibrous web for attaching the end of the web of each web roll to the surface of the roll, in which method the web rolls are wound supported by at least two lower support elements, and in which, during winding, the web is brought onto the roll via the first support element and, upon completing the winding, each completed roll is transferred by a pushing device, whereby in transfer, the support of the roll shifts away from said first support element onto the second support element and the web travelling from the first support element onto the web roll is cut.

  • rolls having yet greater diameters can be processed.
  • the roll is transferred by the pushing device such that, first, the centre of gravity of the roll passes in the machine direction the apex of the second support element, and the web travelling from the first support element onto the web roll is cut, after which the roll is transferred such that its centre of gravity once again passes in the machine direction the apex of the second support element, and the web end attachment unit is brought into its operating position such that it can deliver the adhesive material to the surface of the roll.
