Abstract (en)
[origin: EP2578525A2] The device (1) has a nip (4) formed between a drum (2) and a tambour (3), where a portion of the tambour comprises circumferential grooves. A scraper (6) is arranged behind the nip at the drum, where a blower (8) is arranged behind the nip. The blower comprises multiple nozzles (11), where gas i.e. air, is injectable into the grooves through the nozzles. The blower is arranged co-axially to the tambour. The nozzles are alignable according to a position and nature of the grooves. The blower is adjustable in a blowing direction, and a control device (12) controls the blower. An independent claim is also included for a method for winding a fibrous material web i.e. paper or paperboard web.
