Secure reliable tail threading at the press section
EV Threading Roll SP™ is a tail treading roll that improves tail threading from the press center roll to a separate press. The threading roll presses the tail against the press felt.
EV Threading Roll SP is installed to a separate press, above a press felt and very close to a suction transfer roll. The threading roll rotates on crawling speed during normal run to prevent contamination.
During tail threading, the speed of the threading roll is increased close to normal running speed and the roll is lowered towards the press felt. This creates a nip when the tail is pressed to the press felt.
The threading roll is lifted up to a stand-by position to crawling speed after the tail threading.
- Highly improved tail threading at press section
