<p>A flexible mounting for use in the forming section of a twin forming fabric paper making machine consisting essentially of a base member (1) supported by the paper making machine structure (2) to which is attached a flexible C-shaped beam (3). The C-shaped beam (3) has one edge (4) attached to the base member (1), and a fabric contacting blade (13) attachment means (8) at the other edge. A pressurized loading tube (14) is located within the C-shaped beam (3) between the base member and the second edge of the C-shaped beam. When the pressurized loading tube (14) is loaded, the C-shaped beam (3) flexes thus allowing the blade (13) to move initially into contact with a forming fabric. As the pressurized tube is further loaded, the contact face (22) of the blade (13) 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 (81) whereby liquid accumulated upstream of the blade is vented downstream of the mounting.</p> |
