Hood with a differentiable drying flow for correcting the moisture profile of a papermaking sheet, and corresponding correction process

摘要

The invention relates to a hood 1 divided into a number of compartments 2, 3, 4, themselves comprising spaces for blowing hot air 2a, 2b, 2c, and suction spaces for recycling 2A, 2B etc. The blown air is modulated in temperature by batteries of electrical resistors R1, R2, R3. Obtaining a very high evaporation power without disadvantages. IMAGE
