Papermaking industry drying and processing arrangement with heated cylinder, includes outer pressure hood comprising assembly of cells with individually-controlled heating fluid connections

摘要

The pressure hood (4) comprises individual cells (13). These extend along the run of the web and lie adjacently together. Each cell has individual connections for supply and return of fluid. The pressure and temperature of the fluid are used as control parameters for individual cells. Moisture, roughness, strength and/or shrinkage behavior of the fibrous web are controlled. There are supports (10, 11, 12) below the cylinder (3), comprising one or more support rollers (10, 11), a pressure shoe (12) and/or a support belt.
