Slitter-winder and a method for slitting and winding a fiber web

A method for slitting and winding a fiber web in a slitter-winder comprising an unwinding section, a slitting section and a winding section, the method comprising the steps of:

• unwinding a full-width thick fiber web having a basic weight of at least 200 g/m2 in the unwinding section and slitting and winding said thick fiber web into customer roll(s) in slitting and winding sections;
• wherein the full-width thick fiber web is alternating unwound in the unwinding section from a parent roll in a first unwinder and from a parent roll in a second unwinder;
• wherein a beginning end of a thick fiber web coming from the parent roll in the first unwinder is joined to an end of a thick fiber web coming from the parent roll in the second unwinder by a joining device to form a joint between the beginning end and the end;
• and
• cutting the thick fiber web comprising the joint by a cutting device and removing the joint from the winding section automatically.

A slitter-winder for fiber webs, wherein the slitter-winder is configured to unwind, slit and wind a thick fiber web having a basic weight of at least 200 g/m2 to customer rolls, the slitter winder comprising:

• an unwinding section having a first unwinder and a second unwinder for unwinding the thick fiber web from a parent roll comprising full-width thick fiber web, and a joining device for joining a beginning end of a thick fiber web coming from a parent roll and traveling in a machine direction in the first unwinder to an end of a thick fiber web coming from a parent roll in the second unwinder to form a joint;
• a slitting section after the unwinding section;
• and
• a winding section having a cutting device for forming a cut extending in a cross-machine direction perpendicular to the machine direction for cutting and removing part(s) of the thick fiber web comprising the joint from the winding section.
