| 摘要 |
The invention relates to a process and arrangement for the circulating oil lubrication of the drying section of a paper or cardboard machine. Pressurised lubricant is fed through a bearing of a drying cylinder 7 to both lubricate and cool the bearing. Compressed air is fed to the pipelines 8, 9, 10, 11 of the circulating oil lubrication system in the opposite direction to the direction of the circulating oil lubrication, so that moist vapour occurring in the cover A of the drying section is prevented from getting into the circulating oil lubrication system. <IMAGE>
