HOOD FOR A WIRE PART AND FOR A PRESS SECTION

摘要

The invention concerns a hood for a wire part and/or for a press section in a paper/board machine, comprising walls and a ceiling (10, 20), which form a closed hood around the wire part and/or the press section, air-conditioning being arranged in connection with the hood. The hood walls (10, 20) are composed of outer and inner walls, so that between them there is an air duct for passing a replacement air flow into the interior of the hood towards a substantial middle area of the paper machine through openings that have been made into the inner wall, the replacement air keeping the interior of the hood substantially dry and clean. The walls (10, 20) of the hood comprise a vertical side wall at the driving side, which wall is preferably fixed, and a tending-side vertical side wall and a ceiling, which have been formed as a single wall, which is preferably L-shaped and displaceable. The displaceable hood wall (10, 20) at the tending side is composed of two parts, so that the first hood wall (10) is placed on the wire section (110) and the second hood wall on the press section (120), which wall parts can be displaced apart from the wire part and the press section in opposite directions.
