摘要： An elongated planar or profiled component for a manufacturing machine of a fibrous cellulosic web, such as paper, board or tissue web, is at least partially formed from a composite material having a continuous polymer matrix, and reinforcing inorganic fibers embedded in the continuous polymer matrix. The continuous polymer matrix is biodegradable and the reinforcing inorganic fibers are biodegradable glass fibers. A method is disclosed for recycling elongated planar and/or profiled components used for manufacture of a fibrous web.

摘要： A sheet manufacturing apparatus includes a first transport unit, a second transport belt disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, a suction chamber positioned in an inner side of the second transport belt and configured to create suction inside the suction chamber to suck the web onto the second transport belt, and a current plate positioned inside of the suction chamber to adjust an air current. The current plate has a plurality of holes, and is spaced apart from a surface of the second transport belt such that the air current is diffused between the current plate and the surface of the second transport belt to achieve a uniform suction force in a width direction of the second transport belt.

摘要： A nonwoven fibrous mat or web forming or treating system is disclosed comprising a movable, permeable wire or belt for carrying the fibrous mat or web over at least one suction tube assembly comprising a primary suction tube having a suction slot at the top of the primary suction tube and an exit tube communicating with the primary suction tube mounted beneath the permeable belt to have the suction slot on or close to the bottom surface of the movable belt. The suction slot is at least 3.6 meters long and up to more than 5.3 meters long, and the exit tube of the suction tube assembly communicates with the primary suction tube through an opening in the primary suction tube, the opening being generally centered around a centerline of the suction slot. This primary suction tube assembly provides a more uniform suction distribution along the suction slot and reduces fouling of the suction slot compared with previous suction tube assemblies.

摘要： In a twin wire former, white-water withdrawal means (20) for withdrawing white water (15) dewatered to the opposite side of a roll is arranged to the upstream side of a pressure element (30) to suppress the interference of the dewatered white water (15) with the pressure element (30). This renders it possible to prevent damage to the pressure element (30) that is caused by a collision with white water (15) during dewatering and to manufacture defect-free paper that has even dispersion of fibers.

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。

摘要： A foil blade for use in dewatering devices found in a web forming section of a papermaking machine is described. The improved foil blade according to the present invention is easily installed into and removed from such dewatering devices. The improved foil blade of the present invention is rigidly mounted within the same dewatering devices such that the foil blade does not rotate or change geometry during a papermaking process as a wire or fabric having a stock mixture thereon travels over the foil blade. The improvement resides in providing a loaded clamping assembly for the foil blade. In one embodiment, according to the present invention, the loaded clamping assembly comprises a pneumatic load air tube to rigidly secure the foil blade to a dewatering device in a web-forming section of a papermaking machine. The foil blade being firmly clamped in position by way of the loaded air tube, cannot rotate or change geometry during operation. The loaded clamping assembly further includes a pneumatic unload air tube to unclamp the foil blade from the dewatering device allowing the foil blade to be easily slipped in and out in the cross-machine direction of the papermaking machine. In another embodiment of the present invention, the load air tube is replaced with a spring loaded clamp. In yet another embodiment of the present invention, the load air tube is replaced with a cam operated load mechanism. The loaded clamping assemblies can be arranged in pivoting clamp styles or a sliding clamp style as will be further described herein.

摘要： A suction box for use in a press arrangement in a machine for producing a paper or cardboard web. The suction box includes at least one suction side suctioning the fibrous pulp sheet onto a transport side of at least one felt belt. The suction box further includes at least one non-suction side and at least one slit. A vacuum is created by having air blown out of at least one slit. The vacuum occurs along the felt belt in a run direction of the felt belt. The slit is positioned at an edge of at least one non-suction side of the suction box. The suction box may be disposed on an exit side of a press slit of the press arrangement. The press slit is adapted to treat the fibrous pulp sheet. At least one felt belt is guided, simultaneously with the fibrous pulp sheet, through the press slit. Upon exiting the press slit, the fibrous pulp sheet is suctioned onto at least one felt belt by the suction box.
