摘要： A flexible mounting for use in the forming section of a twin forming fabric paper making machine consisting essentially of a base member supported by the paper making machine structure to which is attached a flexible C-shaped beam. The C-shaped beam has one edge attached to the base member, and a fabric contacting blade attachment means at the other edge. A pressurized loading tube is located within the C-shaped beam between the base member and the second edge of the C-shaped beam. When the pressurized loading tube is loaded, the C-shaped beam flexes thus allowing the blade to move initially into contact with a forming fabric. As the pressurized tube is further loaded, the contact face of the blade is moved into further engagement with the forming fabric. In a preferred construction, the wrap angle of the fabrics at or about the blade leading edge can be minimized. The mounting thus can diminish wear of the fabric as it passes over the blade. The mounting also allows localized flexing in the blade to accommodate localized variations in conditions, such as variations in stock thickness. The mounting can also include vents whereby liquid accumulated upstream of the blade is vented downstream of the mounting.

摘要翻译： 一种用于双成型织物造纸机的成型部分的柔性安装件，其基本上由由构成柔性C形梁的造纸机结构支撑的基部构件组成。 C形梁具有连接到基座构件的一个边缘，以及在另一个边缘处的织物接触叶片附接装置。 加压加载管位于基体与C形梁的第二边缘之间的C形梁内。 当加载加压管被加载时，C形梁弯曲，从而允许叶片最初移动与成形织物接触。 当加压管进一步加载时，刀片的接触面进一步与成形织物接合。 在优选结构中，织物在叶片前缘处或周围的包角可以最小化。 因此，安装件可以减少织物在刀片上的磨损。 安装还允许在叶片中局部弯曲以适应条件的局部变化，例如坯料厚度的变化。 安装件还可以包括通风口，其中积聚在叶片上游的液体在安装件的下游排出。
