The arrangement includes a holding point adapted prior to the last nip and a cutting device. The arrangement further includes a support device adapted at the holding point for supporting the tail during cutting.

Arrangement in tail threading in a multinip calender of a paper machine

In the method for threading a tail ( ) of a paper or board web through a paper or board machine or a section thereof, or through an aftertreatment machine for paper or board or a section thereof, the tail ( ) is prevented from wandering onto the same line with a tail carrier means ( ), such as threading ropes, upstream of the draw point of the tail. The tail ( ) is guided towards the centre line of the machine by subjecting the tail to an effect of force which tends to move the tail towards the centre line of the machine.
