摘要： A dry end of a paper machine located in a paper machine room, comprising a drying cylinder (1; 32) for drying a paper web (5), a hood (2) covering the drying cylinder, and a reel-up (6) for winding the dried paper web into a roll. According to the invention a cover (9) is arranged after the drying cylinder and adapted to extend from the hood to at least the reel-up and to define thereunder a covered space (23) above and on the sides of the web so that the covered space is effectively isolated from the paper machine room. The invention also relates to a method of reducing dust spreading out from the dry end. The method comprises the steps of: providing a cover (9) extending from the hood (2) to at least the reel-up (6); defining by the cover thereunder a covered space (23) for keeping the dust within this space (23); and preventing the dust from spreading from the covered space (23) into the paper machine room.
