The invention relates to a reel-up 3 for receiving and winding into a roll 4 a paper web W that arrives from a drying cylinder 2 in a paper making machine and which drying cylinder 2 is located upstream of the reel-up 3 and which paper web W follows a path of travel from the drying cylinder 2 to the reel-up 3. The reel-up 3 comprises a rotatably mounted reel spool 5 onto which a paper web W can be wound to create a paper roll 4 of increasing diameter and an endless flexible belt 6 mounted for rotation along a predetermined path of travel such that the flexible belt 6 forms a loop. The flexible belt 6 is positioned adjacent to the reel spool 5 to engage the paper web W against the reel spool 5 during winding. The reel-up 3 is 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 belt 6 where the paper web W meets the flexible belt 6 such that a wedge-shaped space WS is formed between the flexible belt 6 and the paper web W. From the point of contact P, the paper web W will be carried by the flexible belt 6 to the reel-spool 5. According to the invention, the reel-up 3 further comprises an air deflector 8 for diverting or evacuating air away from the wedge-shaped space WS formed between the flexible belt 6 and the paper web W. The invention also relates to a method of reeling a paper web.
A reel-up (3) for receiving and winding into a paper roll (4) a paper web (W) that arrives from a drying cylinder (2) in a paper making machine and which drying cylinder (2) is located upstream of the reel-up (3) and which the paper web (W) follows a path of travel from the drying cylinder (2) to the reel-up (3), the reel-up (3) comprising:
