Abstract
The invention relates to a reel-upfor receiving and winding into a rolla paper web W that arrives from a drying cylinderin a paper making machine and which drying cylinderis located upstream of the reel-upand which paper web W follows a path of travel from the drying cylinderto the reel-up. The reel-upcomprises a rotatably mounted reel spoolonto which a paper web W can be wound to create a paper rollof increasing diameter and an endless flexible beltmounted for rotation along a predetermined path of travel such that the flexible beltforms a loop. The flexible beltis positioned adjacent to the reel spoolto engage the paper web W against the reel spoolduring winding. The reel-upis arranged to receive the paper web W at the end of a path of travel of the paper web W which ends in a point of contact P with the flexible beltwhere the paper web W meets the flexible beltsuch that a wedge-shaped space WS is formed between the flexible beltand the paper web W. From the point of contact P, the paper web W will be carried by the flexible beltto the reel-spool. According to the invention, the reel-upfurther comprises an air deflectorfor diverting or evacuating air away from the wedge-shaped space WS formed between the flexible beltand the paper web W. The invention also relates to a method of reeling a paper web.
