Embodiment Construction

[0023] Figure 1 schematically shows the press section of a paper machine and two closed passage spaces 100A, 100B extending from the operating side HP of the machine to the driving side KP of the machine.

[0024] FIG. 2 is a cross-sectional view of the channel space 100 shown in FIG. 1 , and FIG. 3 is a longitudinal sectional view of the channel space 100 shown in FIG. 1 . The passage space 100 includes: a floor surface 101 , a ceiling surface 102 , a first side wall 103 , and a second side wall 104 . The vertical trapezoidal shape of the second side wall 104 is primarily determined by the space available at the installation location. The boxes 200A...200F are attached to the second side wall 104 of the passage space 100, and automatic equipment can be arranged in said boxes. The height h of the passage space 100 is formed such that an operator can walk upright in the space. The width 1 of the passage space in the longitudinal direction is instead formed such that the opera...

Abstract

The wet end of the paper machine comprises at least one passage space (100) which extends from a tending side (HP) of the machine to a drive side (KP) of the machine and is closed in a machine direction, and inside which operating staff can walk in an operating situation safely and protected from ambient conditions between the tending side (HP) of the machine and the drive side (KP) of the machine.

Description

technical field [0001] The invention relates to a paper or board machine. [0002] The device according to the invention relates to a passage space between the driving side and the tending side of a paper or board machine. [0003] In a preferred embodiment of the invention, the access space can also be formed in the automation space, thereby enabling the access space to be used for placing machine control system components or other equivalent components. In this regard, machine control systems include all systems related to the control of machines, such as machine control systems, process control systems, quality control systems, measuring systems and monitoring systems. Background technique [0004] In a paper or board machine in the art, maintenance and operating personnel are not able to safely walk between the drive side and the operating side of the machine at the wet end of the machine (forming and press sections) while the machine is in operation . For maintenance...
